Description

  The present invention relates to a technique for controlling the progress of a baseball game in which a batter character hits a ball object thrown by a pitcher character.

  Conventionally, a baseball game in which an outer frame indicating a strike zone is displayed on a display screen and a batter character strikes a ball object thrown by a pitcher character aiming at the strike zone is known (for example, Patent Document 1). In such a baseball game, the strike zone ball determination is determined simply by looking at the positional relationship between the strike zone and the passing position of the ball object, and whether the pitched ball object is a strike or a ball. The criteria for judging whether or not there was a fixed one.

  By the way, in actual baseball, the judgment of the strike zone is performed by the referee, but in reality, each referee has a slight strike discrepancy. For example, it may be mentioned that the course is sweet or strict in each course such as raising and lowering the strike zone. Highly sweet referees make a decision that captures the higher strike zone wider than the normal strike zone, and if the referee is highly demanding, the decision is taken to capture the higher strike zone narrower than the normal strike zone. Do.

  Therefore, a pitcher with excellent ball control power may take a strategy of seeing the habit of the referee, assuming the strike zone set by the referee, and throwing the ball at the limit of the assumed strike zone.

  In addition, a batter with excellent eye selection predicts that if a ball is thrown on a course in a strike zone where the judgment of the referee is severe, it would normally be judged as a strike if the ball is overlooked. For the time being, you may go to the bat and take a strategy of foulball.

  And such a player's strategy is one factor that excites the baseball game.

JP 2007-222398 A

  However, in the conventional baseball game, there is no game that takes the above-mentioned referee's habit into consideration when determining the strike zone. Therefore, the player cannot take the strategy described above according to the referee's habit, as in an actual baseball game.

  An object of the present invention is to make a game device, a game control program, and a game control method capable of realizing a baseball game full of reality and reflecting the habit of referee existing in real baseball in the progress of the game. Is to provide.

  (1) A game apparatus according to an aspect of the present invention is a game apparatus that executes a baseball game in which a batter character strikes a ball object thrown by a pitcher character, and is in the vicinity of the outer periphery of a strike zone that is set in advance in the game space Conscious information storage means for preliminarily storing consciousness information indicating a course perceived by the referee character, and an outer frame side of the strike zone corresponding to the course indicated by the consciousness information is set as the attention side, and the attention side In order to determine whether or not the ball object has passed in the vicinity, a determination area setting means for setting a determination area outside and inside the strike zone on the basis of the attention side, and the ball object passes through the determination area Counting means, and based on the count value by the counting means, the attention The and a size changing means for changing the size of the strike zone by causing the outer or sliding inside the strike zone.

  A game control program according to another aspect of the present invention is a game control program for causing a computer to execute a baseball game in which a batter character hits a ball object thrown by a pitcher character, and is preset in a game space. In a region near the outer periphery of the strike zone, consciousness information storage means for preliminarily storing consciousness information indicating the course that the referee character is aware of, and the outer edge of the strike zone corresponding to the course indicated by the consciousness information are set as attention sides. And a determination area setting means for setting a determination area outside and inside the strike zone with reference to the target side in order to determine whether or not a ball object has passed near the target side, and the determination area Counting means for counting the number of times the ball object has passed, and the cow Based on the count value by preparative means, it causes a computer to function the target edge as the size changing means for changing the size of the strike zone by causing the outer or sliding inside the strike zone.

  The game control method according to still another aspect of the present invention is a game control method in which a game device executes a baseball game in which a batter character hits a ball object thrown by a pitcher character. In a region in the vicinity of the outer periphery of the strike zone set in advance in the space, the game apparatus has a consciousness information storage means for preliminarily storing consciousness information indicating a course conscious of the umpire character, and the game device corresponds to the course indicated by the consciousness information In order to determine whether the outer edge of the strike zone is the target side and determine whether or not the ball object has passed near the target side, the determination is made outside and inside the strike zone based on the target side. A determination area setting step for setting an area, and a count of the number of times the ball object has passed through the determination area. Comprising a counting step of bets, based on the count value of said count step, and the size changing step of changing the size of the strike zone by sliding the attention sides outside or inside of the strike zone.

  According to these configurations, the consciousness information indicating the course that the referee character is conscious of (for example, the outer side of the strike zone) is stored in advance in the region near the outer periphery of the strike zone. Then, the side of the outer frame of the strike zone corresponding to the course indicated by the consciousness information is set as the attention side for the referee character. Then, determination areas for determining whether or not the ball object has passed near the attention side are set outside and inside the strike zone with the attention side as a reference. Then, the number of times the ball object has passed through this determination area (each of the outside and inside) is counted, and the side of interest is slid outside or inside the strike zone according to the count value, and the size of the strike zone is changed.

  Here, the consciousness information indicating the course that the umpire character is conscious of is information indicating a concept introduced in order to artificially reflect the umpire of the umpire in actual baseball on the game. Specifically, the referee's trap that is the subject of this configuration is simply sweet at the outside corner (if the judgment is subtle, it tends to be judged as a strike), and is stricter (if the judgment is subtle, It is not a single kite that tends to be judged as a ball), but which course is more conscious. For example, if there is a strong awareness of the outside angle, if there are many balls outside the strike zone (ball judgment), the consciousness is attracted to them and the strike zone is slightly expanded outward (attention) Move side out). Conversely, if there are many balls inside the strike zone (strike determination), the consciousness is attracted to them and the strike zone is slightly narrowed inward (moves the attention side inward).

  In other words, in this configuration, when the ball concentrates on a region (attention side) where the consciousness of the referee character is strongly directed, the size of the strike zone is set to change according to the concentration method.

  In addition, since this consciousness information sets information specific to each referee character to be prepared, the referee changes for each game of the game, and the change of the strike zone is different. Can enjoy. Alternatively, instead of assuming a plurality of referee characters, it is possible to simply change consciousness information at random for each game of a game and store the consciousness information in the consciousness information storage means.

  In addition, when the player operates the pitcher character, the strike zone can be expanded by aiming at the outer determination area and throwing the ball object. On the other hand, when the ball object passes the inner determination area, the strike zone becomes narrower. Since there is a possibility, it becomes necessary to pay attention to the pitching, and the game performance is improved accordingly.

  For example, when the player operates the pitcher character, if the strike zone is enlarged and the ball object is thrown while aiming at only the outside determination area, the ball is advanced and disadvantageous to itself. Also, if the ball object is thrown while aiming only at the outside determination area, there is a possibility that the pitching becomes monotonous and hits and home runs occur frequently, which is disadvantageous to itself.

  Accordingly, the player is required to throw the ball object into the outer determination area and the inner determination area in consideration of his / her own profit and disadvantage, and can provide an unprecedented interest to the player.

  Further, when the player is a batter character, the following measures can be taken to avoid the expansion of the strike zone. That is, when there are many balls (ball determination) just outside the strike zone, the consciousness of the referee character is attracted to them, and the strike zone slightly expands outward. In order to avoid this, it is conceivable to suppress the number of balls counted outside the strike zone by fouling the ball object for the time being. However, on the other hand, if you are confident in determining the ball course, the ball object thrown outside the strike zone is a ball that has been determined to be a ball, so you can aim for the foreball.

  As described above, according to this configuration, it is possible to cause various psychological bargaining, and it is possible to progress the game based on a strategy that also considers the judgment by the referee, which could not be realized in the conventional baseball game. A highly entertaining baseball game filled with

  Although the referee character may be displayed on the screen, it is not always necessary to display the screen because the influence on the strike zone is reflected in the game.

  (2) The determination area setting means sets a determination area outside the strike zone as an outside determination area with the attention side as a reference, and sets a determination area inside the strike zone as an inside with the attention side as a reference. Set as a determination area, the counting means counts the number of times the ball object has passed through the outer determination area and the number of times the ball object has passed through the inner determination area, respectively, and the size changing means When one of the number of outside passes and the number of times of passing inside reaches the first threshold value, if the number of times of passing outside is larger than the number of times of passing inside, the target side is slid toward the outside of the strike zone. If the strike zone is increased and the number of inside passes is greater than the number of outside passes, Reducing the strike zone by sliding attention sides inside the strike zone is preferred.

  According to this configuration, with respect to the determination area, the area outside the strike zone is set as the outer determination area with the target side as a reference, and the inner area is set as the inner determination area. Then, the number of times the ball object has passed in each of the inside determination area and the outside determination area is counted, and the number of outside passes and the number of inside passes are counted. Then, when the outer side determination area first reaches the first threshold value, the attention side is slid toward the outside of the strike zone, and when the inner side determination area reaches the first threshold value first, the attention side is the strike zone. Strike zone is changed toward the inside.

  As described above, according to the present configuration, the determination of the expansion or reduction of the strike zone is based on the premise that “one of the number of outside passes and the number of inside passes has reached the first threshold value”. For example, it is possible to avoid dizzying changes such as changing the strike zone only when the first ball passes through the determination region, and it is possible to change the strike zone at an appropriate timing. Furthermore, instead of simply changing the strike zone by the number of outside passes or the absolute number of inside passes, “if the number of outside passes is larger than the number of inside passes, the target side is slid toward the outside of the strike zone. By increasing the strike zone and the number of inside passes is greater than the number of outside passes, slide the attention side to the inside of the strike zone. Thus, the strike zone is changed and the influence of the consciousness of the referee character can be appropriately reflected.

  (3) It is preferable that the size changing means sets the sliding amount of the attention side based on a difference between the outer passage count and the inner passage count.

  According to this configuration, the sliding amount of the target side is set according to the difference between the number of outside passes and the number of inside passes. Therefore, when the player operates the pitcher character, if he simply wants to expand the strike zone, the ball will be expanded most widely by continuously throwing the ball outside the strike zone until the first threshold is satisfied. However, if it is necessary to pitch inward by bargaining with the batter, the amount of expansion will be reduced. In other words, even if the player intends to expand the strike zone, the player will be bound by pitching, and complicated strategy is required, so that the fun as a game is improved.

  (4) In the size changing unit, when one of the outer passage count and the inner passage count reaches the first threshold value, a difference between the outer passage count and the inner passage count is equal to or less than a second threshold value. In this case, it is preferable not to slide the attention side.

  According to this configuration, when the difference between the outer passage count and the inner passage count is not so large, the attention side is not slid. By providing such a setting, an unnatural strike zone change in the following count can be avoided. For example, assuming that the first threshold is 15 balls, and the number of outside passes and the number of inside passes are both 14 balls, if the next ball passes the outside determination area, the number of outside passes is 15 balls. In order to satisfy the first threshold value, the strike zone increases outward. However, when compared in terms of the number of balls, the number of outside passes is 15 balls and the number of inside passes is 14 balls, and the strike zone varies widely although it is not so different, which is unnatural. Therefore, as in this configuration, the above situation can be avoided if the strike zone is changed only when the difference between the number of times of passing outside and the number of times of passing inside exceeds the second threshold value. For example, if the second threshold is set to 10 balls, in the above example, the strike zone changes because the number of outside passes is 15 balls and the number of inside passes is 4 balls (the difference between them is 11 balls) A reasonable balance.

  In addition, as a player who operates the pitcher character, it is impossible to slide the attention side unless the ball objects of the outer determination area and the inner determination area are thrown away with the intention to slide the attention edge. As a result, the game performance is improved accordingly.

  (5) It is preferable to further comprise a notifying means for notifying the course indicated by the consciousness information.

  According to this configuration, since the course that the referee character is aware of is notified to the player, the player can recognize the course that the referee character is aware of, that is, the referee character's habit.

  (6) It is preferable that the notification means notifies the course indicated by the consciousness information by displaying the strike zone on a display screen of a display device so that the concentration becomes lighter toward the attention side.

  According to this configuration, since the strike zone is displayed in gradation so that the density becomes lighter toward the attention side, the player can recognize the course conscious of the referee character from the density of the density.

  (7) The size changing unit determines the position of the attention side when one of the outer passage number and the inner passage number reaches the first threshold value, and the notification unit includes the size changing unit. When the position of the attention side is fixed, the attention side is preferably displayed as a line segment.

  According to this configuration, after the attention side is determined, the position is displayed as a line segment, so that the player can clearly recognize the outer edge of the strike zone. Even if a ball object is thrown on, it can be recognized that the attention side cannot be slid.

  (8) When the consciousness information indicates a plurality of courses, the determination area setting unit sets the outer frame sides of the strike zone corresponding to each course as attention sides, and individually determines the determination regions for each attention side. The counting means individually counts the number of times the ball object has passed in each determination area, and the size changing means can change the strike zone by sliding each attention side individually. preferable.

  According to this structure, it can be taken into the game that the umpire character is conscious of a plurality of courses. In this case, the above processing is executed for each attention side corresponding to each course, and the size of the strike zone is changed. Therefore, it is possible to express the individuality of the referee character from the variation of the course, and it is possible to further enhance the interest of the game.

  (9) Preferably, the counting means does not perform the counting operation when the batter character hits the ball object even when the ball object passes through the determination area.

  According to this configuration, when the player is on the attacking side, a foul ball is used as the ball object thrown in the strike zone marginal determination region, thereby preventing variation in the size of the strike zone. Therefore, it is possible to provide the attacking player with an opportunity to make a new strategy, and to enhance the interest of the game.

  According to the present invention, it is possible to provide a technique for realizing a highly interesting baseball game by reflecting the referee's habit in the progress of the game.

  Hereinafter, a game device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a game device according to one embodiment of the present invention. In the following description, a home video game apparatus configured by connecting a home video game machine to a home television will be described as an example of the game apparatus, but the present invention is not particularly limited to this example. The present invention can be similarly applied to a portable game device or mobile phone in which a monitor is integrated, or a personal computer that functions as a game device by executing a game control program according to the present invention.

  The game device shown in FIG. 1 includes a consumer game machine 100 and a television 200. The home-use game machine 100 is loaded with a computer-readable recording medium 300 on which a game program is recorded, and the game program is appropriately read to execute the game.

  A consumer game machine 100 includes a CPU (Central Processing Unit) 1, a bus line 2, a graphics data generation processor 3, an interface circuit (I / F) 4, a main memory 5, a ROM (Read Only Memory) 6, and an expansion circuit 7. , Parallel port 8, serial port 9, drawing processor 10, audio processor 11, decoder 12, interface circuit (I / F) 13, buffers 14 to 16, recording medium drive 17, memory 18, and controller 19. The television 200 includes a television monitor 21, an amplifier circuit 22 and a speaker 23.

  The CPU 1 is connected to the bus line 2 and the graphics data generation processor 3. The bus line 2 includes an address bus, a data bus, a control bus, and the like. The CPU 1, interface circuit 4, main memory 5, ROM 6, decompression circuit 7, parallel port 8, serial port 9, drawing processor 10, audio processor 11, decoder 12 And the interface circuit 13 are connected to each other.

  The drawing processor 10 is connected to the buffer 14. The audio processor 11 is connected to the buffer 15 and the amplifier circuit 22. The decoder 12 is connected to the buffer 16 and the recording medium drive 17. The interface circuit 13 is connected to the memory 18 and the controller 19.

  The television monitor 21 of the television 200 is connected to the drawing processor 10. The speaker 23 is connected to the amplifier circuit 22.

  In addition, when the game apparatus is configured with a personal computer, a workstation, or the like as a core, the television monitor 21 or the like corresponds to a computer display. In addition, the decompression circuit 7, the drawing processor 10, the audio processor 11, and the like are respectively provided on a part of the game control program data recorded on the recording medium 300 or on hardware on an expansion board installed in an expansion slot of the computer. Correspond. The interface circuit 4, the parallel port 8, the serial port 9, and the interface circuit 13 correspond to hardware on an expansion board mounted in an expansion slot of the computer. The buffers 14 to 16 correspond to the storage areas of the main memory 5 or the expansion memory, respectively.

  Next, each component shown in FIG. 1 will be described. The graphics data generation processor 3 serves as a coprocessor for the CPU 1. That is, the graphics data generation processor 3 performs coordinate conversion and light source calculation, for example, calculation of a fixed point format matrix or vector by parallel processing.

  The main processing performed by the graphics data generation processor 3 includes predetermined data based on the coordinate data, movement amount data, rotation amount data, and the like of each vertex in the two-dimensional or three-dimensional space of the image data supplied from the CPU 1. There are processing for obtaining address data of the processing target image on the display area and returning it to the CPU 1, processing for calculating the luminance of the image according to the distance from the virtually set light source, and the like.

  The interface circuit 4 is used for an interface of a peripheral device such as a pointing device such as a mouse or a trackball. The main memory 5 is composed of a RAM (Random Access Memory) or the like. The ROM 6 stores program data serving as an operating system for the game device.

  The decompression circuit 7 performs decompression processing on a compressed image compressed by intra coding conforming to the MPEG (Moving Picture Experts Group) standard for moving images and the JPEG (Joint Photographic Experts Group) standard for still images. The decompression processing includes decoding processing (decoding of data encoded by VLC: Variable Length Code), inverse quantization processing, IDCT (Inverse Discrete Cosine Transform) processing, intra image restoration processing, and the like.

  The drawing processor 10 performs a drawing process on the buffer 14 based on a drawing command issued by the CPU 1 every predetermined time T (for example, T = 1/60 seconds in one frame).

  The buffer 14 is constituted by a RAM, for example, and is divided into a display area (frame buffer) and a non-display area. The display area is composed of a development area for image data to be displayed on the display surface of the television monitor 21. The non-display area is composed of storage areas such as data for defining a skeleton, model data for defining polygons, animation data for causing the model to move, pattern data indicating the contents of each animation, texture data, and color palette data.

  Here, the texture data is two-dimensional image data. The color palette data is data for designating a color such as texture data. The CPU 1 records these data in the non-display area of the buffer 14 in advance at a time from the recording medium 300 or in a plurality of times according to the progress of the game.

  The drawing command includes a drawing command for drawing a stereoscopic image using a polygon and a drawing command for drawing a normal two-dimensional image. Here, the polygon is a polygonal two-dimensional virtual figure, and for example, a triangle or a quadrangle is used.

  A drawing command for drawing a stereoscopic image using polygons is polygon vertex address data indicating the storage position of polygon vertex coordinate data on the display area of the buffer 14, and the storage position of the texture to be pasted on the polygon 14 on the buffer 14. Is performed on each of the color address data indicating the storage position on the buffer 14 and the color data indicating the texture brightness.

  Among the above data, the polygon vertex address data on the display area is converted by the graphics data generation processor 3 by performing coordinate conversion of the polygon vertex coordinate data in the three-dimensional space from the CPU 1 based on the movement amount data and the rotation amount data. It is replaced with polygon vertex coordinate data in two dimensions. The luminance data is determined by the graphics data generation processor 3 based on the distance from the position indicated by the polygon vertex coordinate data after the coordinate conversion from the CPU 1 to the light source virtually arranged.

  The polygon vertex address data indicates an address on the display area of the buffer 14. The drawing processor 10 performs a process of writing texture data corresponding to the display area range of the buffer 14 indicated by the three polygon vertex address data.

  An object such as a character in the game space is composed of a plurality of polygons. The CPU 1 stores the coordinate data of each polygon in the three-dimensional space in the buffer 14 in association with the corresponding skeleton vector data. When the character is moved on the display screen of the television monitor 21 by an operation of the controller 19 to be described later or when the viewpoint position where the character is viewed is changed, The following processing is performed.

  That is, the CPU 1 obtains the graphics data generation processor 3 from the three-dimensional coordinate data of the vertices of each polygon held in the non-display area of the buffer 14, the skeleton coordinates, and the rotation amount data. Polygon movement amount data and rotation amount data are given.

  The graphics data generation processor 3 sequentially obtains the three-dimensional coordinate data after moving and rotating each polygon based on the three-dimensional coordinate data of the vertex of each polygon and the movement amount data and rotation amount data of each polygon.

  Of the three-dimensional coordinate data of each polygon thus obtained, the coordinate data in the horizontal and vertical directions are supplied to the drawing processor 10 as address data on the display area of the buffer 14, that is, polygon vertex address data.

  The drawing processor 10 writes the texture data indicated by the texture address data assigned in advance on the display area of the buffer 14 indicated by the three polygon vertex address data. As a result, on the display screen of the television monitor 21, an object in which textures are pasted on a large number of polygons is displayed.

  A drawing command for drawing a normal two-dimensional image indicates vertex address data, texture address data, color palette address data indicating the storage position on the buffer 14 of color palette data indicating the color of the texture data, and luminance of the texture. This is performed on the luminance data. Among these data, the vertex address data is obtained by the coordinate conversion of the vertex coordinate data on the two-dimensional plane from the CPU 1 by the graphics data generation processor 3 based on the movement amount data and the rotation amount data from the CPU 1.

  The audio processor 11 stores ADPCM (Adaptive Differential Pulse Code Modulation) data read from the recording medium 300 in the buffer 15, and the ADPCM data stored in the buffer 15 becomes a sound source.

  Also, the audio processor 11 reads ADPCM data from the buffer 15 based on, for example, a clock signal having a frequency of 44.1 kHz. The audio processor 11 performs processing such as pitch conversion, noise addition, envelope setting, level setting, and reverb addition on the read ADPCM data.

  When the audio data read from the recording medium 300 is PCM (Pulse Code Modulation) data such as CD-DA (Compact Disk Digital Audio), the audio processor 11 converts the audio data into ADPCM data. Further, the processing for the PCM data by the program is directly performed on the main memory 5. The PCM data processed on the main memory 5 is supplied to the audio processor 11 and converted into ADPCM data. Thereafter, the various processes described above are performed, and sound is output from the speaker 23.

  As the recording medium drive 17, for example, a DVD-ROM drive, a CD-ROM drive, a hard disk drive, an optical disk drive, a flexible disk drive, a silicon disk drive, a cassette medium reader, or the like is used. In this case, as the recording medium 300, a DVD-ROM, a CD-ROM, a hard disk, an optical disk, a flexible disk, a semiconductor memory, or the like is used.

  The recording medium drive 17 reads image data, audio data, and program data from the recording medium 300 and supplies the read data to the decoder 12. The decoder 12 performs error correction processing by ECC (Error Correction Code) on the reproduced data from the recording medium drive 17 and supplies the data subjected to the error correction processing to the main memory 5 or the audio processor 11.

  For example, a card-type memory is used as the memory 18. The card type memory is used for holding various game parameters at the time of interruption, such as holding the state at the time of interruption when the game is interrupted.

  The controller 19 is an operation device used by the player who is an operator to input various operation commands, and sends an operation signal corresponding to the operation of the player to the CPU 1. The controller 19 includes a first button 19a, a second button 19b, a third button 19c, a fourth button 19d, an up key 19U, a down key 19D, a left key 19L, a right key 19R, and L1 buttons 19L1, L2. A button 19L2, an R1 button 19R1, an R2 button 19R2, a start button 19e, a select button 19f, a left stick 19SL and a right stick 19SR are provided.

  The up direction key 19U, the down direction key 19D, the left direction key 19L, and the right direction key 19R are used, for example, to give the CPU 1 a command for moving a character or cursor up, down, left, or right on the screen of the television monitor 21. .

  The start button 19e is used to instruct the CPU 1 to load a game program from the recording medium 300. The select button 19f is used to instruct the CPU 1 to make various selections related to the game program loaded from the recording medium 300 to the main memory 5.

  The buttons and keys of the controller 19 except for the left stick 19SL and the right stick 19SR are turned on when pressed from the neutral position by an external pressing force, and return to the neutral position when the pressing force is released. It consists of an on / off switch that turns off.

  The left stick 19SL and the right stick 19SR are stick-type controllers having almost the same configuration as a so-called joystick. This stick-type controller has an upright stick, and can be tilted over a 360 ° direction including front, rear, left and right with a predetermined position of the stick as a fulcrum. The left stick 19SL and the right stick 19SR are connected to the CPU 1 via the interface circuit 13 using the values of the x-coordinate in the left-right direction and the y-coordinate in the front-rear direction as the operation signals according to the tilt direction and tilt angle of the stick. To send.

  The first button 19a, the second button 19b, the third button 19c, the fourth button 19d, the L1 button 19L1, the L2 button 19L2, the R1 button 19R1, and the R2 button 19R2 are added to the game control program loaded from the recording medium 300. It is used for various functions accordingly.

  Next, a schematic operation of the above game device will be described. When the recording medium 300 is loaded in the recording medium drive 17, when a power switch (not shown) is turned on and the game apparatus is turned on, the recording medium 300 is based on the operating system stored in the ROM 6. The CPU 1 instructs the recording medium drive 17 to read the game program from. As a result, the recording medium drive 17 reads image data, audio data, and program data from the recording medium 300. The read image data, audio data, and program data are supplied to the decoder 12, and the decoder 12 performs error correction processing on each data.

  The image data that has been subjected to error correction processing by the decoder 12 is supplied to the decompression circuit 7 via the bus line 2. The image data that has been subjected to the expansion processing described above by the expansion circuit 7 is supplied to the drawing processor 10, and is written into the non-display area of the buffer 14 by the drawing processor 10. The audio data that has been subjected to the error correction processing by the decoder 12 is written into the buffer 15 via the main memory 5 or the audio processor 11. Program data that has been subjected to error correction processing by the decoder 12 is written into the main memory 5.

  Thereafter, the CPU 1 causes the game to proceed based on the game control program stored in the main memory 5 and the content instructed by the player using the controller 19. In other words, the CPU 1 appropriately performs control of image processing, control of sound processing, control of internal processing, and the like based on content that the player instructs using the controller 19.

  As image processing control, for example, the calculation of the coordinates of each skeleton or the calculation of the vertex coordinate data of polygons from the pattern data corresponding to the animation instructed to the character, the obtained three-dimensional coordinate data and the graphics data of the viewpoint position data Supply to the generation processor 3, issue of a rendering command including address data and luminance data on the display area of the buffer 14 obtained by the graphics data generation processor 3 are performed.

  As control of audio processing, for example, issue of an audio output command to the audio processor 11, specification of level, reverb, etc. are performed. As control of the internal processing, for example, calculation according to the operation of the controller 19 is performed.

  Next, the game executed based on the game program recorded on the recording medium 300 will be described. The game in this embodiment is based on a baseball game.

  FIG. 3 is a screen diagram for explaining an outline of the baseball game executed by the game device according to the present embodiment. In this baseball game, the batter character CL1 hits the ball object BL thrown by the pitcher character CL2 in the game space which is a virtual three-dimensional space. Specifically, as shown in FIG. 3, this baseball game is a baseball game in which the pitcher character CL2 throws the ball object BL and the batter character CL1 returns the ball object BL with the bat object BT.

  In this baseball game, when the player is on the attack side, the player operates the controller 19 to move the meet cursor K displayed in the outer frame WK indicating the strike zone on the display screen, so that the ball object BL moves to the home base. When the vicinity is reached, the meat cursor K is positioned on the ball object BL and a batting command is input. Then, the bat object BT is displayed as a swing, and the ball object BL is hit back.

  In this baseball game, the strike zone is not fixed at the start of the game, and after the game is started, the strike zone is determined by the processing described later, and then the strike zone is displayed in the outer frame WK as shown in FIG. Is done.

  Next, main functions of the game apparatus when a baseball game is played using the game apparatus configured as described above will be described. FIG. 2 is a main functional block diagram of the game apparatus shown in FIG.

  As shown in FIG. 2, the game device functionally includes an operation unit 410, a display unit 420, a program execution unit 430, a data storage unit 440, and a program storage unit 450.

  The operation unit 410 includes the controller 19 and the like, and receives various inputs necessary for the game to progress by the player. In the present embodiment, when the player is on the attack side and the game apparatus is on the defensive side, the operation unit 410 moves the move cursor for moving the meet cursor and the hit command for determining the hit timing of the ball object. Is entered. When the player is on the defensive side and the game device is on the attacking side, the operation unit 410 causes the pitcher character to start a pitching operation and a course setting command for setting the course of the ball object. Accept.

  The display unit 420 includes the television 200 shown in FIG. 1 and displays various images under the control of the program execution unit 430.

  The program execution unit 430 includes the CPU 1 and the graphics data generation processor 3 shown in FIG. 1, and the like. The program execution unit 430 includes a game progress control unit 431, a determination region setting unit 432 (an example of a determination region setting unit), and a count unit 433 (a count unit). An example), a size changing unit 434 (an example of a size changing unit), a strike zone display unit 435 (an example of a notifying unit), an impact determining unit 436, and an impact power setting unit 437.

  The game progress control unit 431 is for progressing the baseball game. Specifically, when the player is on the attack side, the game progress control unit 431 causes the pitcher character displayed on the display unit 420 to perform a pitching action at a predetermined timing, sets the trajectory of the ball object, The ball object is moved and displayed on the display unit 420 according to the set trajectory.

  Further, when the player is on the defensive side, the game progress control unit 431 causes the pitcher character displayed on the display unit 420 to perform a pitching operation when a pitching start command is input from the player to the operation unit 410. The trajectory of the ball object is set in accordance with the course setting command input to, and the ball object is moved and displayed on the display unit 420 according to the set trajectory.

  The determination area setting unit 432 sets the outer frame side of the strike zone corresponding to the course indicated by the consciousness information stored in the consciousness information storage unit 441 as the attention side, and whether the ball object has passed near the attention side. In order to determine whether or not, a determination area is set outside and inside the strike zone with reference to the target side. Here, the strike zone is a rectangular area set in advance at a predetermined position in the game space.

  FIG. 4 is a diagram showing a virtual three-dimensional space (game space) in which a baseball game is developed by the game device according to the embodiment of the present invention. 4 indicates a direction parallel to a straight line L3 connecting the center O2 of the pitcher mound and the center O3 of the home base HB in the virtual three-dimensional space, and indicates the traveling direction of the ball object BL. In addition, y indicates a vertical direction, and x indicates a direction orthogonal to the vertical direction and the traveling direction. Here, the xz plane is parallel to the ground surface ES, and the x and z coordinates define each position of the ground surface ES. The vertical direction is a direction orthogonal to the ground surface ES. In the present embodiment, y increases as the distance from the ground surface ES increases. Further, z increases from the center O2 of the pitcher mound toward the center O3 of the home base HB. Further, x is, for example, + on the left side and-on the right side when viewed in the + z direction. The origin of the x, y, and z axes is assumed to be at the center O2.

  The strike zone SZ is a rectangular area that is set on a movable area SF that is a plane that passes through the center O3 and is parallel to the xy plane, and is surrounded by an outer frame WK. The game space is set based on the strike zone.

  The center OS of the strike zone SZ is located a predetermined distance away from the center O3 in the + y direction, and corresponds to the middle of the strike zone.

  The meat cursor K moves on the movable area SF in accordance with the movement command input to the operation unit 410. However, this is only an example, and the meet cursor K may be moved on a plane slightly shifted in the z direction from the movable area SF. As the size of the movable area SF, a size slightly larger than the size of the strike zone SZ can be adopted. A pitcher character CL2 and a batter character CL1 shown in FIG. 3 are arranged on the ground surface ES. A catcher character and a referee character are arranged on the + z side from the home base HB.

  If the pitcher character CL2 is thrown to the right, for example, a point SP separated by a distance dL in the −x direction from a point SP ′ that is H (O) away from the center O2 in the y direction is the release of the ball object BL by the pitcher character CL2. It becomes a point.

  FIG. 5 is a diagram for explaining the processing of the determination area setting unit 432. In FIG. 5, among the four sides W1 to W4 constituting the outer frame WK, the side W4 is set as the target side. Further, the outer frame WK shown in FIG. 5 indicates the outer frame WK when viewed from the referee character side, that is, the outer frame WK in the −z direction view shown in FIG. Then, the determination area setting unit 432 sets the side W4 as the attention side CW from the consciousness information, sets the determination area D1 outside the strike zone SZ with the attention side CW as a reference, as the outer determination area D12, and the attention side The determination area D1 inside the strike zone SZ is set as the inner determination area D11 with reference to CW.

  Consciousness information is information indicating the concept introduced in order to artificially reflect the referee's habit in real baseball on the game, and information indicating the course that the referee character is aware of in the area near the outer periphery of the strike zone It is. As consciousness information, for example, there are high, low, left, and right. Here, the area in the vicinity of the outer periphery refers to a frame-shaped area that extends between the outer side and the inner side of the strike zone, which gives the outer frame WK some thickness. The higher, lower, left, and right consciousness information indicates that the umpire character is conscious of the higher, lower, left, and right courses of the strike zone when viewed from the character.

  In addition, the attention side is associated in advance with each of the high, low, left, and right indicated by the consciousness information. That is, higher consciousness information is associated with side W1, lower consciousness information is associated with side W2, left consciousness information is associated with side W3, and right consciousness information is associated with side W4. Yes.

  Therefore, the determination area setting unit 432 sets the side W1 as the attention side when the consciousness information indicates high, sets the side W2 as the attention side when the consciousness information indicates low, and the consciousness information indicates the left The edge W3 is set as the attention side, and when the consciousness information indicates the right, the side W4 is set as the attention side.

  As shown in FIG. 5, the length L1 of the inner determination area D11 is determined based on the size of the ball object, and for example, a length about twice the diameter of the ball object can be adopted. it can.

  Similarly to the inner determination area D11, the length L2 of the outer determination area D12 is determined based on the size of the ball object. For example, the same length as the width L1 is adopted.

  The widths L1 and L2 may be different from each other, for example, the length may be appropriately changed according to the referee character. In this case, the identification information of the referee character may be associated with the consciousness information in advance, and the lengths of the widths L1 and L2 may be associated in advance. In addition, a form in which the referee character is not changed may be adopted. In this case, for example, the consciousness information may be changed randomly or by player setting for each game.

  Note that the determination area D1, the inner determination area D11, and the outer determination area D12 illustrated in FIG. 5 are not displayed on the display unit 420. The outer frame WK is not displayed on the display unit 420 until the strike zone is determined.

  In addition, the consciousness information may indicate two or more courses. FIG. 6 is a diagram showing a determination area D1 that is set when the consciousness information indicates two courses. In FIG. 6, the consciousness information is high and right. Here, the height corresponds to the side W1, and the right corresponds to the side W4. Therefore, the determination area setting unit 432 sets the determination area D1 with the side W1 as a reference, and sets the determination area D1 with the side W4 as a reference.

  The determination area D1 with the side W1 as a reference and the determination area D1 with the side W4 as a reference may have the same size or different sizes. In this case, the width L1 and the width L2 of the determination area D1 with the side W1 as a reference and the widths L1 and L2 of the determination area D1 with the side W2 as a reference may be associated in advance with the consciousness information. In FIG. 6, as in FIG. 5, the determination area D1 and the like are not displayed.

  Returning to FIG. 2, the counting unit 433 counts the number of times the ball object has passed through the determination area D1. Here, the counting unit 433 counts the number of outside passes that the ball object has passed through the outside determination area D12 and the number of inside passes that the ball object has passed through the inside determination area D11.

  Further, when two or more determination regions D1 are set by the determination region setting unit 432, the count unit 433 individually counts the number of times of passing outside and the number of times of passing inside in each determination region D1. For example, when two determination areas D1 are set as shown in FIG. 6, count processing is separately performed on the determination area D1 set on the side W1 and the determination area D1 set on the side W4.

  Note that the counting unit 433 does not perform the counting process when the ball object is hit by the batter character even when the ball object passes through the determination area D1. As a result, when the player is on the attacking side, the ball object thrown at the edge of the strike zone is changed to a foul ball, thereby preventing fluctuation of the strike zone, that is, a strike or ball or a ball with a delicate course is cut. You can make a strategy that you did not have in the traditional baseball game.

  The size changing unit 434 changes the size of the strike zone SZ by sliding the target side CW to the outside or the inside of the strike zone SZ based on the count value by the count unit 433.

  Here, the size changing unit 434 moves the attention side CW to the outside of the strike zone when one of the outer passage count and the inner passage count reaches the first threshold and the outer passage count is larger than the inner passage count. Increase the strike zone by sliding towards it.

  On the other hand, when one of the number of outside passes and the number of inside passes reaches the first threshold and the inside pass count is larger than the outside pass count, the size changing unit 434 directs the attention side CW to the inside of the strike zone. To reduce the strike zone.

  For example, if the first threshold value is 15, in FIG. 5, when the ball object passes 15 times in the inner determination area D11 before the outer determination area D12, the side W4 that is the attention side CW is on the left side. Translated to narrow the strike zone.

  Further, when the ball object passes through the outer determination area D12 15 times before the inner determination area D11, the side W4 that is the target side CW is translated to the right side, and the strike zone is widened.

  In addition, the size changing unit 434 sets the slide amount of the attention side CW based on the difference between the number of outside passes and the number of inside passes. FIG. 7 is a diagram illustrating a state in which the attention side CW is slid. In FIG. 7, when the number of outside passes first reaches the first threshold first, and the difference between the number of outside passes and the number of inside passes is Δk, the slide amount Δx of the target side CW is based on the value of the difference Δk. It is determined.

  In this case, a function for linearly increasing the slide amount Δx as the difference Δk increases may be determined in advance, and the slide amount Δx may be determined using this function.

  Then, as shown in FIG. 7, the size changing unit 434 translates the target side CW by the slide amount Δx toward the outside of the strike zone SZ. Thereby, the strike zone SZ increases. In FIG. 7, the side W4 that is the target side CW is slid rightward by the slide amount Δx. Therefore, the strike zone SZ is wider in the right direction than the initial strike zone SZ. As the maximum value of the slide amount Δx, for example, the width L2 of the outer determination area D12 may be adopted.

  On the other hand, when the number of times of inner passage first reaches the first threshold value, the slide amount Δx is obtained from the difference Δk between the number of times of inner passage and the number of times of outer passage, and the target side CW can be translated toward the inside of the strike zone SZ That's fine. Note that, for example, the width L1 of the inner determination area D11 may be adopted as the maximum value of the sliding amount Δx to the inside of the strike zone SZ of the attention side CW.

  In addition, when one of the number of outside passes and the number of inside passes reaches the first threshold, and the difference Δk between the number of outside passes and the number of inside passes is less than or equal to the second threshold, The CW may not be slid.

  For example, if the number of outside passes first reaches the first threshold value and the difference Δk at that time is equal to or less than the second threshold value, the attention side CW is not slid outside the strike zone SZ. Further, if the number of times of inner passage first reaches the first threshold value and the difference Δk at that time is equal to or smaller than the second threshold value, the attention side CW is not slid to the inner side of the strike zone SZ.

  By doing so, the difference between the number of times of inner passage and the number of times of outer passage is not significant, and it is possible to prevent the strike zone from changing against the player's intention.

  Here, for example, 10 (pieces) can be set as the second threshold. In addition to the difference in the number, a ratio of the numbers can be adopted as the second threshold value. In this case, for example, the ratio of the side with a large number of passes and the side with a small number of passes may be set to 2: 1.

  Further, when two or more attention sides CW are set, the size changing unit 434 individually calculates the slide amount Δx of each attention side CW, and individually slides each attention side CW according to the calculated slide amount Δx. Let

  For example, consider a case where the sides W1 and W4 are set as the target side CW as shown in FIG. In this case, in the determination area D1 set in the side W1, when the difference Δk is larger than the second threshold when the number of inner passages or the number of outer passages exceeds the first threshold, the side W1 is in the strike zone SZ. If the difference Δk is larger than the second threshold at the time when the number of inner passages or the number of outer passages exceeds the first threshold in the determination area D1 set to the side W4 by sliding inward or outward, the side W4 is It is slid inside or outside the strike zone SZ.

  Returning to FIG. 2, the strike zone display unit 435 notifies the player of the course indicated by the consciousness information of the referee character. Specifically, the strike zone display unit 435 notifies the course indicated by the consciousness information by displaying the strike zone SZ on the display unit 420 using a grayscale image whose density becomes lighter toward the target side CW.

  When the position of the attention side CW is determined by the size changing unit 434, the strike zone display unit 435 displays the attention side CW as a line segment, thereby determining the position of the attention side CW in the strike zone SZ. This is notified to the player.

  FIG. 8A shows a strike zone SZ that is displayed when the side W4 is the target side CW, as shown in FIG. FIG. 8B shows the strike zone SZ displayed after the size of the strike zone SZ in FIG. 8A is determined.

  In the case of FIG. 8A, the strike zone SZ is displayed as a grayscale image whose transparency increases from the side W3 toward the side W4. Note that the transparency is constant even in the vicinity of the side W3 having the lowest transparency, and therefore the ball object passing near the side W3 can be seen through. That is, the strike zone SZ is displayed like a cloud until the size is determined. Various colors such as white and gray can be adopted as the color of the strike zone displayed like a cloud.

  Such a display of the transparent strike zone can be easily realized by combining the image data of the grayscale image representing the strike zone SZ and the background image data using, for example, an α blending technique.

  As shown in FIG. 8A, since the transparency near the side W4 is high, the referee character is aware of the side W4 and can recognize that the size of the side W4 may vary. .

  In FIG. 8A, the grayscale image display range is within the strike zone SZ. However, the present invention is not limited to this, and the grayscale image display range may be determined so as to protrude somewhat from the strike zone SZ. In addition to the grayscale image, the outer frame WK of the strike zone SZ may be displayed with a dotted line. In this case, the player can be notified more clearly that the size of the strike zone SZ has not been determined.

  FIG. 9A shows a strike zone SZ displayed when the two sides W1 and W4 are the target side CW as shown in FIG. FIG. 9B shows the strike zone SZ displayed after the position of the side W1 is fixed, and FIG. 9C shows the strike zone SZ displayed after the position of the side W4 is fixed. Yes.

  In the case of FIG. 9 (A), the strike zone SZ is displayed as a grayscale image whose transparency is high for a while as it goes from the side W3 to the side W4 and becomes transparent for a while as it goes from the side W2 to the side W1. . That is, the strike zone SZ is displayed by a grayscale image whose transparency increases for a while as it goes from the lower left vertex of the strike zone SZ to the upper right vertex.

  Therefore, the player recognizes that the umpire character is aware of the side W1 and the side W4 by visually recognizing the strike zone SZ in FIG. 9A, and the two sides may change. Can do.

  Summarizing the above, the strike zone display unit 435 displays the grayscale image that is gradation-displayed so that the transparency decreases for a while from one target side CW toward the side opposite to the target side as many as the number of the target side CW. The strike zone SZ is displayed by superimposing.

  In FIG. 8A, since the target side CW is one of the sides W4, when the position of the side W4 is determined by the size changing unit 434, the strike zone SZ is determined. Therefore, as shown in FIG. 8B, the display mode of the strike zone SZ is switched from the grayscale image to the outer frame WK. For convenience of explanation, in FIG. 8B, the size of the strike zone SZ is not changed compared to that in FIG. 8A, but when the attention side CW is slid by the size changing unit 434, the size is changed accordingly. Thus, the size of the strike zone SZ changes as compared to FIG.

  On the other hand, in FIG. 9A, since there are two attention sides CW and the timing of determining the slide amount of each attention side CW is different, the display mode of the strike zone SZ is different from the case of FIG. Switching method is different.

  In FIG. 9A, it is assumed that the position of the side W1 is first determined among the attention side CW. In this case, as shown in FIG. 9B, line segments indicating each of the three sides W1 to W3 excluding the side W4 whose position is not fixed are displayed. At this time, the display of the gray image whose transparency decreases for a while as it goes to the sides W1 to W2 is terminated, and only the display of the gray image whose transparency decreases for a while as it goes to the sides W4 to W3 is continued.

  Accordingly, the player can recognize that the position of the side W1 has been determined. When the position of the side W4 that is the remaining attention side CW is determined, the display of the grayscale image is terminated, and the line segment of the side W4 is displayed. Then, as shown in FIG. 9C, the strike zone SZ is displayed only by the outer frame WK.

  Thereby, the player can recognize that the size of the strike zone SZ has been determined.

  Returning to FIG. 2, the hit determination unit 436 receives the ball command by the batter character according to the hit input signal output from the operation unit 410 when the hit command is input from the player in order to hit the ball object to the batter character. The hit timing of the object is determined, and when the ball object overlaps the meat cursor at the determined hit timing, it is determined that the batter character was able to hit the ball object.

  FIG. 10 is a diagram when the virtual three-dimensional space shown in FIG. 4 is viewed from the x-axis direction. As shown in FIG. 10, the hit determination unit 436 causes the batter character to start swinging the bat object from the time when the hit command is input to the operation unit 410, and continues until the bat object reaches the movable area SF. The time when the time has passed is determined as the hitting timing. If the ball object BL and the meat cursor K overlap at the hitting timing, it is determined that the ball object BL has been hit by the batter character.

  However, in this case, the difficulty level of the game becomes extremely high, and there is a possibility that the game is not interesting. Therefore, in the present embodiment, for example, at the hitting timing, the z component of the ball object BL is a distance in the −z direction from the movable area SF by a distance d1 and a distance in the + z direction from the movable area SF. If the extension line of the ball object BL exists at a position apart from d2 and intersects with the meat cursor K on the movable area SF, it is determined that the ball object BL and the meat cursor K overlap. May be.

  Here, as an extension line of the ball object BL, for example, a straight line extending from the center of gravity G1 of the ball object BL in the direction of the speed of the ball object BL when the hitting timing is determined can be employed.

  Alternatively, when the z component of the ball object BL exists between a position that is a distance d1 away from the movable area SF and a position that is a distance d2 away from the movable area SF at the hitting timing, A movable area SF ′ parallel to the movable area SF passing through the center of gravity G1 is set, the meat cursor K on the movable area SF is projected onto the set movable area SF ′, and the projected meat cursor K and the ball are projected. When the object BL overlaps, it may be determined that the ball object BL and the meet cursor K overlap.

  As d1 and d2, the same distance as the z component length of the strike zone from the movable area SF, or a distance obtained by adding or subtracting some margin can be used.

  Returning to FIG. 2, when the hit determining unit 436 determines that the ball object BL and the meat cursor K overlap at the hit timing, the hit power setting unit 437 sets the hit power for hitting the ball object BL. To do.

  Here, the hitting power setting unit 437 sets the hitting power larger as the passing position of the center of gravity G1 of the ball object BL with respect to the meet cursor K is closer to the center of gravity of the meet cursor K at the hitting timing. In this embodiment, the initial velocity V0 of the ball object BL can be adopted as the hitting power, and the hit determination unit 436 determines the magnitude and direction of the reference initial velocity Vref that is predetermined for the ball object BL. By correcting, the initial velocity V0 of the ball object BL is obtained.

  FIGS. 11A to 11C are diagrams showing a calculation process of the initial velocity V0 of the hit ball object BL. As shown in FIG. 11A, it is assumed that the center of gravity of the region where the ball object BL and the meat cursor K overlap is a point P4 (u, v). However, u is a coordinate axis passing through the center O1 of the meet cursor K and parallel to the x axis, and v is a coordinate axis passing through the center O1 and parallel to the y axis.

  In this case, the impact power setting unit 437 obtains the distance ds between the point P4 and the center O1, obtains a correction coefficient β for setting the reference initial speed Vref to be smaller as the distance ds increases, and uses the correction coefficient β as a reference. By multiplying the initial speed Vref (β · Vref), the magnitude of the reference initial speed Vref is corrected, and the magnitude of the corrected reference initial speed Vref may be set as the magnitude of the initial speed V0 of the ball object BL. .

  The hitting power setting unit 437 may output the correction coefficient β, input the distance ds, and calculate the correction coefficient β using a predetermined function in which the correction coefficient β increases as the distance ds decreases. .

  Next, a method of calculating the direction of the initial velocity V0 of the ball object BL by the hitting power setting unit 437 will be described with reference to FIGS. As shown in FIG. 11B, the striking power setting unit 437 has a predetermined reference direction Dref indicating the direction of the initial speed Vref, as shown in FIG. 11B, in accordance with the value of v at the point P4 shown in FIG. The pitch angle θ is corrected, and the corrected pitch angle θ in the reference direction Dref is set as the pitch angle of the initial speed V0.

  Specifically, the striking power setting unit 437 sets the correction amount in the reference direction Dref to 0 when v at the point P4 is located on the u-axis, and sets v of the point P4 when v at the point P4 is positive. Depending on the value, the pitch angle θ in the reference direction Dref is rotated clockwise by a predetermined angle. When v at the point P4 is negative, the pitch angle θ in the reference direction Dref is counterclockwise according to the value of v at the point P4. What is necessary is just to rotate a predetermined angle.

  Note that the pitch angle θ of the reference initial speed Vref is set in a counterclockwise direction with respect to the z axis.

  Further, if u at the point P4 is positive, the striking power setting unit 437 sets the yaw angle θ2 in the reference direction Dref as a reference with respect to the z axis according to the value of u at the point P4 as shown in FIG. As shown in FIG. 4, the rotation is performed by a predetermined angle in the clockwise direction (+ θ2 side), and the yaw angle θ2 in the reference direction Dref after the rotation is set as the yaw angle of the initial speed V0.

  On the other hand, if u at the point P4 is negative, the striking power setting unit 437 rotates the yaw angle θ2 in the reference direction Dref counterclockwise (−θ2 side) based on the z axis according to the value of u at the point P4. The yaw angle θ2 in the reference direction Dref after the rotation is set as the yaw angle of the initial speed V0.

  In addition, as shown in FIG. 10, the hitting power setting unit 437 is located at the hit timing where the center of gravity G1 of the ball object BL is shifted from the movable area SF in the z direction. The yaw angle θ2 in the reference direction Dref shown in FIG. 11C is rotated according to the amount of deviation.

  Specifically, when the batter character is a right batter, if the center of gravity G1 of the ball object BL is located on the −z direction side from the movable area SF in FIG. 10, it is determined that the batter character has rushed. The Then, according to the distance d between the center of gravity G1 of the ball object BL and the movable area SF, the yaw angle θ2 shown in FIG. 11C is rotated counterclockwise by a predetermined angle with respect to the z axis.

  On the other hand, when the batter character is a right batter, if the center of gravity G1 of the ball object BL is located on the + z direction side from the movable area SF, it is determined that the batter character is delayed. Then, according to the distance d, the yaw angle θ2 shown in FIG. 11C is rotated clockwise by a predetermined angle with respect to the z axis.

  When the batter character is a left batter and rushes, the yaw angle θ2 shown in FIG. 11C is rotated clockwise by a predetermined angle according to the distance d, and when the batter is delayed, the yaw angle θ2 is a distance. Depending on d, it is rotated counterclockwise by a predetermined angle.

  Returning to FIG. 2, the data storage unit 440 includes, for example, the main memory 5 and functions as a consciousness information storage unit 441 and an image storage unit 442. The consciousness information storage unit 441 stores the consciousness information described above.

  The image storage unit 442 stores image data necessary for realizing the baseball game. For example, the image storage unit 442 stores image data of a defensive character, a batter character, a bat object, a baseball field background image, a pitcher character, and the like. To do. Here, as the image data of the background image of the baseball field, for example, image data created in advance by projecting a virtual three-dimensional model created in advance in a virtual three-dimensional space from a predetermined viewpoint can be adopted. .

  The program storage unit 450 includes, for example, the recording medium drive 17 and includes a computer-readable recording medium 451. The recording medium 451 is composed of the recording medium 300 and stores a game control program according to the present invention. When the game control program is read from the recording medium 300 and the game control program is recorded in the main memory 5, the main memory 5 functions as the program storage unit 450.

  FIG. 12 is a flowchart showing processing when the game apparatus moves the ball object according to the embodiment of the present invention. FIG. 13 is a flowchart subsequent to the flowchart shown in FIG. In the following flowchart, a case where there is one attention side CW will be described as an example.

  First, in step S1, the game progress control unit 431 reads out image data such as the batter character CL1, the bat object BT, the background image of the baseball field, the pitcher character CL2, and the fielder character from the image storage unit 442, and displays it on the display unit 420. Display and make initial settings. In this case, an image as shown in FIG. 3 is displayed on the display unit 420, for example. At this stage, the outer frame WK shown in FIG. 3 is not displayed on the display unit 420.

  Next, the determination area setting unit 432 reads the consciousness information stored in the consciousness information storage unit 441, identifies the attention side CW among the four sides of the outer frame WK according to the read consciousness information, and identifies the identified attention side The determination area D1 is set with reference to CW (step S2). In this case, for example, as shown in FIG. 8A, the determination region D1 is set in the attention side CW.

  Next, the strike zone display unit 435 displays, on the display unit 420, a grayscale image whose transparency decreases in the direction from the target side CW toward the side opposite to the target side CW according to the target side CW set in step S3. The strike zone SZ is displayed (step S3).

  Next, when the player is on the attack side, the pitcher character starts pitching when a predetermined timing comes, or when the player is on the defense side, when a pitching start command is input by the player (step S4).

  At this time, the game progress control unit 431 changes the display mode of the pitcher character CL2 so that the pitcher character CL2 throws the ball object BL. In addition, the game progress control unit 431 sets the trajectory of the ball object BL based on the ability information of the pitcher character CL2, and moves and displays the ball object BL on the display unit 420 according to the set trajectory.

  Next, as described above, the hit determination unit 436 determines whether or not the batter character CL1 has hit the ball object BL (step S5). When it is determined that the batter character CL1 has hit the ball object BL (YES in step S5), the hitting power setting unit 437 sets the hitting power of the ball object BL as described above (step S6). Then, the game progress control unit 431 sets the trajectory of the ball object BL according to the hitting power of the ball object BL set by the hitting power setting unit 437, and the ball object BL is displayed on the display unit 420 according to the set trajectory. Move and display.

  In this case, for example, the game progress control unit 431 corrects the ball trajectory serving as the reference of the ball object BL according to the magnitude and direction of the initial velocity V0 of the ball object BL, which is the hitting power, thereby reducing the trajectory of the ball object Just decide.

  On the other hand, when it is determined in step S5 that the batter character CL1 has failed to hit the ball object BL (NO in step S5), the counting unit 433 determines whether or not the ball object BL has passed the determination area D1. (Step S7).

  In this case, the counting unit 433 determines that the ball object BL has passed the determination area D1 if at least a part of the ball object BL overlaps the determination area D1.

  It is also assumed that the ball object BL passes over the attention side CW and passes through both the inner determination area D11 and the outer determination area D12. In this case, for example, if the center of gravity G1 of the ball object BL passes through the inner determination area D11, the counting unit 433 determines that the ball object BL has passed through the inner determination area D11, and the center of gravity G1 passes through the outer determination area D12. If so, it is determined that the ball object BL has passed the outside determination area D12.

  When it is determined that the ball object BL has not passed the determination area D1 (NO in step S7), the process returns to step S4, and when it is determined that the ball object BL has passed the determination area D1 ( If YES in step S7), the process proceeds to step S8.

  That is, when the ball object BL does not pass the determination area D1, the counting process by the counting unit 433 is unnecessary, and the process returns to step S4.

  Next, in step S8, the counting unit 433 increments the number of times of inner passage when the ball object BL passes the inner determination area D11, and increases the outer count when the ball object BL passes the outer determination area D12. Increase the number of passes by one.

  Next, the size changing unit 434 calculates a difference Δk between the number of outside passes and the number of inside passes when the number of outside passes is equal to or greater than the first threshold (YES in Step S9). If the difference Δk is equal to or greater than the second threshold (YES in step S10), the slide amount Δx of the attention side CW is obtained according to the difference Δk, and the attention side CW is directed to the outside of the strike zone SZ by the slide amount Δx. To determine the position of the target side CW (step S11).

  On the other hand, when the difference Δk is less than the second threshold (NO in step S10), the size changing unit 434 determines the position of the attention side CW without sliding the attention side CW (step S12).

  If the number of outside passes is not equal to or greater than the first threshold (NO in step S9), but the number of times of inner passage is equal to or greater than the first threshold (YES in step S13), the size changing unit 434 It is determined whether or not the difference Δk between the number of times of passing inside and the number of times of passing outside is equal to or greater than a second threshold (step S14). If the difference Δk is equal to or larger than the second threshold (YES in step S14), the size changing unit 434 obtains the slide amount Δx corresponding to the difference Δk, and moves the attention side CW by the slide amount Δx inside the strike zone. Slide toward (step S15).

  In step S14, when the difference Δk is less than the second threshold value (NO in step S14), the size changing unit 434 determines the position of the attention side CW without sliding the attention side CW (step S16). .

  If NO is determined in step S13, that is, if neither the number of outside passes or the number of inside passes is equal to or greater than the first threshold, the process returns to step S4.

  In step S <b> 17, the strike zone display unit 435 displays the target side CW and the remaining three sides whose positions have been determined as line segments, and switches the display mode of the strike zone SZ from the grayscale image based on transparency to the outer frame WK.

  Thereby, the player can recognize that the strike zone SZ has been established. Thereafter, the game proceeds in the strike zone SZ determined until one game is over. When one game is over, the strike zone returns to the initial state before the change.

  By the way, in this embodiment, once the strike zone is determined (changed), the subsequent pitching does not affect the size of the strike zone after the change. This is because if the strike zone changes too frequently, the gameability will be impaired, and even in an actual game, the judgment tendency of a strike zone of a game will not always fluctuate throughout the game. This is to reflect the tendency in the game because it tends to be confirmed at the beginning.

  When there are two or more attention sides CW, the processes of steps S4 to S17 are individually executed for each attention side CW, and the position of the attention side CW is sequentially determined.

  As described above, according to the game device, when a certain number of ball objects BL are thrown in the vicinity of the attention side CW corresponding to the course of the strike zone SZ that the referee is aware of, it is induced. It is possible to realize a game effect as if the umpire character slides the side of interest and changes the strike zone SZ.

  Thereby, it is possible to incorporate the referee's habit into the game as in an actual baseball game. Further, when the player operates the pitcher character CL2, the player can change the size of the strike zone SZ by throwing a ball object in the vicinity of the attention side corresponding to the course that the referee character is aware of. Strategy of the game can be made to be advantageous. As a result, it is possible to develop a strategy that could not be established in a conventional baseball game, and to advance the game, thereby further increasing the interest of the game.

  In addition, the following aspect can be employ | adopted for this invention.

  (1) When starting one game, the player may select a favorite referee character. In this case, when the player selects a favorite professional baseball team, one referee character may be selected from a plurality of referee characters. The referee character here is not the jury but the main referee.

  In this case, the identification information of the referee character and the consciousness information of the referee character may be associated with each other and stored in advance in the consciousness information storage unit 441.

  (2) In the above description, the strike zone SZ is displayed as a transparent grayscale image until the strike zone SZ is determined. However, the present invention is not limited to this. For example, the attention side CW is displayed with a dotted line, and the remaining sides are displayed. You may display with a solid line. Here, when there are a plurality of attention sides CW, when the position of a certain attention side CW is determined, the attention side CW after the determination is a solid line, the attention side CW whose position is not determined is a dotted line, and the attention side The sides other than CW may be displayed with solid lines.
