Description

  The present invention relates to a game apparatus, a game apparatus control method, and a program that are suitable for easily understanding a direction in a virtual space.

  A game in which a player moves his / her body and plays is widespread in amusement halls and the like. For example, Patent Document 1 discloses a dance game device that guides the timing of stepping and the like, and allows a player to experience a dance sensation by stepping on a step in time with music. In recent years, there are dance games that require not only steps but also movements using the entire body such as arms and legs. In such a game, in general, in order to make it easier for the player to understand the direction and timing of moving his arms and legs, a character who dances with an exemplary choreography is displayed on the screen.

Japanese Patent No. 3003851

  However, conventionally, the direction in which the character is projected is fixed in one direction, and it may be difficult for the player to see depending on the action of the character. For example, when a character punches or kicks forward, it may be difficult for the player to discern the movement because the player's body appears with his hands and feet superimposed on the character's body. On the other hand, if the direction in which the character is projected is simply changed to make the movement of the character easier to see, there is a problem that it becomes difficult to know in which direction the original direction has been changed.

  SUMMARY OF THE INVENTION The present invention solves the above-described problems, and an object thereof is to provide a game device, a game device control method, and a program suitable for making it easy to grasp the direction in the virtual space.

  A game device according to a first aspect of the present invention includes a display unit, a moving unit, and a sign unit, and is configured as follows. Hereinafter, a dance game in which steps are taken according to the direction indicated by an object moving in the screen will be described as an example.

  The display unit displays on the screen an image representing a state in which the character placed in the virtual space is viewed from the viewpoint placed in the virtual space.

  Here, the character is, for example, a character that is placed in a virtual space and dances by taking exemplary steps. The viewpoint is, for example, the position of the virtual camera arranged in the virtual space. The display unit displays an image on which the state of the character dancing with the virtual camera is photographed.

  The moving unit moves the viewpoint in the virtual space.

  For example, when the virtual camera is arranged at a predetermined position in the forward direction of the character, the moving unit moves the position of the virtual camera from the position in the forward direction of the character to the position in the direction of the right side of the character.

  The sign unit places the sign at a sign position determined relative to the character in the virtual space before the moving unit moves the viewpoint, and moves the viewpoint after the moving unit moves the viewpoint. Erase from within.

  The sign position determined relative to the character is, for example, the position of the chest in the forward direction of the character that is a predetermined distance away from the character in the virtual space. The sign is, for example, an arrow-shaped object indicating the forward direction of the character. For example, the sign unit places an arrow-shaped object on the character's chest before the virtual camera moves, and erases the arrow-shaped object after the virtual camera moves.

  According to the present invention, the player can immediately and easily recognize the change of the viewpoint of the virtual camera and the direction of the character in the virtual space after the change due to the movement of the sign. As described above, when the body is moved by imitating a character, it becomes easy to recognize the action of the character. In particular, it is possible to realize a game device that can effectively assist the player's play by introducing the movement of the above-mentioned signs in a scene where it is difficult to determine the movement of the limbs or the like only by looking at the character from one direction. .

  The moving unit may move the viewpoint instantaneously.

  For example, the moving unit instantaneously moves the virtual camera from the forward direction of the character to the right side surface of the character.

  According to the present invention, in a rhythm game in which timing is important, the direction in which the virtual space is projected can be changed in time for the required action.

  In addition, the sign unit places the sign in the virtual space only before the first time when the viewpoint should move, and erases the sign from the virtual space only after the second time from the time when the viewpoint moves. You may make it do.

  For example, the first time is 2 seconds and the second time is 1 second. In this case, the sign unit places an arrow-shaped object when it is two seconds before the time when the virtual camera is moved by the moving unit, and the arrow-shaped object is displayed for one second from the time when the virtual camera is moved. Display the object. Then, after one second has elapsed from the time when the virtual camera is moved, the sign unit deletes the arrow-shaped object from the virtual space.

  According to the present invention, since the sign is displayed for a predetermined time before and after the change of the direction in which the virtual space is projected, the player can grasp the direction before the change.

  The sign position may be determined relative to the front foot of the character.

  For example, the sign displayed before and after the movement of the viewpoint is displayed at the front foot of the character.

  According to the present invention, the sign can be displayed so that the movement of the character's leg or arm is not hidden by the sign.

  A game apparatus control method according to a second aspect of the present invention is a control method executed by a game apparatus including a display unit, a moving unit, and a sign unit, and is configured as follows.

  In the display step, the display unit displays an image representing a state in which the character placed in the virtual space is viewed from the viewpoint placed in the virtual space.

  In the moving process, the moving unit moves the viewpoint in the virtual space.

  In the labeling process, before the moving unit moves the viewpoint, the labeling unit arranges the label at a label position determined relative to the character in the virtual space, and after the moving unit moves the viewpoint, Erase the sign from the virtual space.

  A program according to another aspect of the present invention is configured to cause a computer to function as the game device and to cause the computer to execute the control method.

  The program of the present invention can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, it is possible to provide a game device, a game device control method, and a program suitable for making it easy to grasp the direction in the virtual space.

(Outline configuration of information processing device)
First, a typical information processing apparatus in which the game apparatus according to the embodiment is realized will be described. In the following, in order to facilitate understanding, an embodiment in which the present invention is realized using an information processing device for games will be described, but the embodiment described below is for explanation, It is not intended to limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

  FIG. 1 is a schematic diagram showing a schematic configuration of a typical information processing apparatus 100 that performs the functions of the game apparatus according to the embodiment of the present invention by executing a program. Hereinafter, a description will be given with reference to FIG.

  The information processing apparatus 100 includes a central processing unit (CPU) 101, a read only memory (ROM) 102, a random access memory (RAM) 103, an interface 104, a controller 105, an external memory 106, and an image processing unit 107. A DVD-ROM (Digital Versatile Disc ROM) drive 108, a NIC (Network Interface Card) 109, an audio processing unit 110, and a mat type controller 111.

  The CPU 101 controls the overall operation of the information processing apparatus 100, is connected to each component, and exchanges control signals and data. Further, the CPU 101 uses arithmetic operations such as addition / subtraction / multiplication / division, logical sum, logical product, etc. using an ALU (Arithmetic Logic Unit) (not shown) for a storage area called a register (not shown) that can be accessed at high speed. , Logic operations such as logical negation, bit operations such as bit sum, bit product, bit inversion, bit shift, and bit rotation can be performed. In addition, the CPU 101 itself is configured so that saturation operations such as addition / subtraction / multiplication / division for multimedia processing, vector operations such as trigonometric functions, etc. can be performed at a high speed, and those provided with a coprocessor. There is.

  The ROM 102 stores an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, the program stored in the DVD-ROM is read to the RAM 103 and the CPU 101 starts execution. The The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for game progress and chat communication. Further, the CPU 101 provides a variable area in the RAM 103 and performs an operation by directly operating the ALU on the value stored in the variable, or temporarily stores the value stored in the RAM 103 in the register. Processing is performed on the register, and the result of the operation is written back to the memory.

  The controller 105 is connected via the interface 104. The controller 105 receives an operation input performed when the player executes the game.

  The external memory 106 is detachably connected via the interface 104. The external memory 106 stores rewritable data indicating game play status (past results, etc.), game progress data, chat communication log (record) data in the case of a network match, and the like. The The player can store these data in the external memory 106 as appropriate by inputting an instruction via the controller 105.

  The image processing unit 107 processes the data read from the DVD-ROM by an image arithmetic processor (not shown) included in the CPU 101 or the image processing unit 107, and then processes the processed data on a frame memory ( (Not shown). The image information stored in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor connected to the image processing unit 107. Thereby, various image displays are possible.

  Further, the image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed.

  In addition, when the virtual space is configured in three dimensions, polygon information that is arranged in the three-dimensional space and to which various texture information is added is rendered by the Z buffer method, and a predetermined viewpoint position is used. It is also possible to perform a high-speed execution of a calculation that obtains a rendering image obtained by looking down at a polygon arranged in the virtual space in the direction of a predetermined line of sight.

  Further, the CPU 101 and the image arithmetic processor cooperate to draw a character string as a two-dimensional image in the frame memory or draw it on the surface of each polygon according to the font information that defines the character shape. It is.

  The DVD-ROM mounted on the DVD-ROM drive 108 stores a program for realizing the game and image data and sound data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 108 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  The NIC 109 is used to connect the information processing apparatus 100 to a computer communication network (not shown) such as the Internet, and is based on the 10BASE-T / 100BASE-T standard used when configuring a LAN (Local Area Network). Or modems that connect to the Internet using telephone lines, ISDN (Integrated Services Digital Network) modems, ADSL (Asymmetric Digital Subscriber Line) modems, and cables that connect to the Internet using cable television lines A modem or the like, and an interface (not shown) that mediates between them and the CPU 101 are configured.

  The audio processing unit 110 converts audio data read from the DVD-ROM into an analog audio signal, and outputs the analog audio signal from a speaker or headphones connected thereto. Further, under the control of the CPU 101, sound effects and music data to be generated during the progress of the game are generated, and sound corresponding to this is output from a speaker or headphones.

  When the sound data recorded on the DVD-ROM is MIDI (Musical Instrument Digital Interface) data, the sound processing unit 110 refers to the sound source data included in the sound data and converts the MIDI data into PCM (Pulse Code Modulation) data. Convert. If the compressed audio data is in ADPCM (Adaptive Differential PCM) format or Ogg Vorbis format, it is expanded and converted to PCM data. The PCM data can be output by performing D / A (Digital / Analog) conversion at a timing corresponding to the sampling frequency and outputting it to a speaker. As the audio data, it is possible to use MP3 (MPeg audio layer-3) data or the like in which PCM data obtained by digitizing audio waveform data is compressed to reduce the size. Also, like MIDI (Music Instruction Data Interface) data, data that defines the pitch, tone length, volume, and timbre type is prepared, and the sound source waveform data prepared in advance is selected and transformed accordingly. May be adopted.

  The mat type controller 111 is connected via the interface 104. In the present invention, it is also possible to connect a plurality of mat type controllers 111 to the information processing apparatus 100. The mat-type controller 111 receives an operation input performed by the player when playing the game. FIG. 2 is an explanatory diagram showing the appearance of the mat type controller 111. Hereinafter, the mat type controller 111 will be described with reference to FIG.

  FIG. 2 is a schematic view of the mat-type controller 111 when the mat-type controller 111 installed on the floor is viewed from directly above. In a predetermined area of the mat-type controller 111, a button 111L for receiving an input for instructing “left” from the player, a button 111R for receiving an input for instructing “right” from the player, and a button for receiving an input instructing “up” from the player 111U, a button 111D for receiving an input indicating “down” from the player, a button 111Y for receiving an input indicating approval of a predetermined operation from the player, and a button 111N for receiving an input indicating rejection of the predetermined operation from the player, respectively. Has been placed. The player can press the buttons 111L, 111R, 111U, 111D, 111Y, and 111N at an arbitrary timing. The CPU 101 determines whether or not the buttons 111L, 111R, 111U, 111D, 111Y, and 111N are pressed.

  In the present embodiment, the mat-type controller 111 includes six buttons 111L, 111R, 111U, 111D, 111Y, and 111N. However, the number of buttons is not limited to six, and may be five or less or seven or more. Good.

  Moreover, it is good also as operation input of a game play by catching the motion of the whole body of a player by using an infrared camera etc. instead of the mat type | mold controller 111. FIG.

  In addition, the information processing apparatus 100 uses a large-capacity external storage device such as a hard disk so as to perform the same function as the ROM 102, the RAM 103, the external memory 106, the DVD-ROM mounted on the DVD-ROM drive 108, and the like. You may comprise.

  The information processing apparatus 100 described above corresponds to a so-called “consumer video game apparatus”, but the present invention can be realized as long as it performs image processing to display a virtual space. Therefore, the present invention can be realized on various computers such as a mobile phone, a portable game device, a karaoke apparatus, and a general business computer.

  For example, a general computer includes an CPU, a RAM, a ROM, a DVD-ROM drive, and an NIC as in the information processing apparatus 100, and an image processing unit having a simpler function than the information processing apparatus 100. In addition to having a hard disk as an external storage device, a flexible disk, a magneto-optical disk, a magnetic tape, and the like can be used. Further, not the controller 105 but a keyboard or a mouse is used as an input device.

  Hereinafter, a schematic configuration of the game apparatus according to the embodiment realized in the information processing apparatus 100 will be described with reference to FIGS. A DVD-ROM storing a game program and data is loaded into the DVD-ROM drive 108 and the information processing apparatus 100 is turned on to execute the program, thereby realizing the game apparatus according to the embodiment. Is done. In the following embodiments, it is assumed that the game device executes a dance game shown below.

(Outline of the game)
First, a dance game related to a game image generated by the image generation device of each embodiment will be described.

  In the game image of the dance game of FIG. 3, a plurality of types of target objects MO1 to MO4 are synchronized with the rhythm of the musical piece to be played, along the moving lane La (lane corresponding to the type of object) from below. It shows how they appear sequentially, move upwards, and then disappear. The target objects MO1 to MO4 represent arrow symbols in different directions. The target object MO1, which is a right-pointing arrow symbol, instructs the player to take a step in the right direction. Similarly, the target object MO2 that is a downward arrow symbol indicates a step backward, the target object MO3 that is an upward arrow symbol is forward, and the target object MO4 that is a left arrow symbol indicates a left step. To do. These target objects MO1 to MO4 appear from the lower end (starting point) of the moving lane La, move upward in the moving lane La, and disappear at the upper end (ending point) of the moving lane La.

  In addition, in the game image of the dance game, determination objects HO1 to HO4 having the same shape as the target objects MO1 to MO4 are displayed fixed to a predetermined area (determination area HA). The player is required to take a step in the direction indicated by the target objects MO1 to MO4 at the timing when the target objects MO1 to MO4 completely overlap the determination objects HO1 to HO4 (hereinafter referred to as “overlap timing”). That is, it is required to press the button 111R at the timing when the target object MO1 completely overlaps the determination object HO1 (overlap timing). Similarly, pressing the button 111D is required when the target object MO2 completely overlaps the determination object HO2, and pressing the button 111U when the target object MO3 completely overlaps the determination object HO3. It is required to press the button 111L at the timing when the target object MO4 is completely overlapped with the determination object HO4.

  When the player steps in the direction indicated by the target objects MO1 to MO4 at the overlapping timing (the buttons 111L, 111R, 111U, and 111D are pressed), the score is added. For example, as shown in “123400” in FIG. Each score is displayed on the screen. On the other hand, if there is no input by the player at the overlapping timing, or if the step is not taken in the direction indicated by the target objects MO1 to MO4, no score is obtained or the score is subtracted. Note that a higher score may be obtained as the error between the timing of stepping and the overlapping timing is smaller.

  In the game image, a character 300 and a mat-type controller 400 are displayed. The character 300 dances an exemplary dance while stepping in overlapping directions in the directions indicated by the target objects MO1 to MO4. In the present embodiment, the character 300 dances so as to have a mirror image relationship with the player, but is not limited thereto. For example, the character 300 displayed in the game image may move in the same direction as the player with his back to the player.

(Outline configuration of game device according to embodiment)
As shown in FIG. 4, the game device 200 according to the embodiment includes a display unit 201, a moving unit 202, and a sign unit 203.

  The display unit 201 displays an image representing a state in which a character placed in the virtual space is viewed from a viewpoint placed in the virtual space.

  Here, it is assumed that the viewpoint is the position of the virtual camera arranged in the virtual space. For example, the display unit 201 displays an image (FIG. 6) that shows a state viewed in the direction 801 from the virtual camera 701 arranged in the forward direction of the character 300 in FIG. 5.

  In the present embodiment, the CPU 101 and the image processing unit 107 cooperate to function as the display unit 201.

  The moving unit 202 moves the viewpoint in the virtual space.

  For example, the moving unit 202 moves the position of the virtual camera 1 second before the movement so that the movement of the character is easy to see according to the game program. For example, as shown in FIG. 5, the arm 301 of the character 300 is moved by a movement distance 501 in parallel with the ground of the virtual space. In this case, the moving unit 202 changes the position of the virtual camera 701 to the position of the virtual camera 702 one second before the time when the arm 301 is moved so that the movement of the arm 301 can be easily seen. Then, the display unit 201 displays an image (FIG. 9) showing a state seen from the virtual camera 702 in the direction 802 on the screen.

  The moving unit 202 may instantaneously move the viewpoint (the position of the virtual camera). In this case, for example, if the display unit 201 displays a frame image (FIG. 6) showing a state seen from the virtual camera 701, the next frame shows a state (FIG. 9) seen from the virtual camera 702. The display unit 201 displays the image of FIG. That is, when the moving unit 202 instantaneously moves the viewpoint, the image in FIG. 6 is instantaneously changed to the image in FIG. 9.

  In the present embodiment, the CPU 101 and the image processing unit 107 cooperate to function as the moving unit 202.

  The sign unit 203 arranges the sign at a sign position determined relative to the character in the virtual space before the moving unit 202 moves the viewpoint, and after the moving unit 202 moves the viewpoint, Is deleted from the virtual space.

  Here, it is assumed that before the moving unit 202 moves the viewpoint, for example, it is a first time before the time when the viewpoint should move. In addition, it is assumed that the time after the moving unit 202 moves the viewpoint is after the second time from the time when the viewpoint moves. Hereinafter, the first time is “2 seconds” and the second time is “1 second”.

  In addition, the sign position determined relative to the character is used as the front foot of the character.

  For example, the time when the moving unit 202 moves from the position of the virtual camera 701 to the position of the virtual camera 702 (that is, the time one second before the time when the arm 301 starts to be moved by the moving distance 501). Thus, the sign unit 203 arranges the sign 601 in the virtual space. The display unit 201 displays the game image (FIG. 7) on which the sign 601 is arranged on the screen. Here, the sign 601 indicates the forward direction of the character at the present time, and is displayed so as to be superimposed on the matting controller 400.

  The sign unit 203 places the sign 601 in the virtual space for one second after being moved from the position of the virtual camera 701 to the position of the virtual camera 702 by the moving unit 202. The display unit 201 displays a game image (FIG. 8) including a sign 601 representing a state viewed from the virtual camera 702 on the screen.

  Then, one second after moving from the position of the virtual camera 701 to the position of the virtual camera 702, the sign unit 203 deletes the sign 601 from the virtual space. The display unit 201 displays a game image (FIG. 9) representing a state viewed from the virtual camera 702 from which the sign 601 has been deleted on the screen. Then, the position of the virtual camera is moved at a time one second before the time when the arm 301 is moved by the moving distance 501, and the sign 601 is erased one second after the movement, so that the sign 601 is erased simultaneously, The arm 301 of the character 300 moves by a moving distance 501.

  Further, for example, as shown in FIG. 10, it is assumed that the character 300 is facing leftward when viewed from the virtual camera 701 and the arm 302 of the character 300 is moved by a movement distance 502 parallel to the ground of the virtual space. Then, for example, the moving unit 202 changes the position of the virtual camera 701 to the position of the virtual camera 703 one second before the time when the arm 302 is moved so that the movement of the arm 302 can be easily seen.

  In this case, the sign unit 203 places the sign 602 at the front foot of the character 300 at a time point that is 2 seconds before the time when the position of the virtual camera is moved, and the display unit 201 moves in the direction 801 from the virtual camera 701. An image showing the appearance (FIG. 11) is displayed. For one second after the position of the virtual camera is moved by the moving unit 202, the sign unit 203 places the sign 602 in the virtual space. The display unit 201 displays a game image (FIG. 12) that includes a sign 602 and represents a state viewed from the virtual camera 703. After 1 second, the sign unit 203 erases the sign 602 from the virtual space, and the display unit 201 displays an image from which the sign 602 has been erased.

  In the present embodiment, the CPU 101 and the image processing unit 107 cooperate to function as the sign unit 203.

(Operation of Game Device According to Embodiment)
Hereinafter, operations performed by each unit of the game apparatus 200 according to the present embodiment will be described. When the game apparatus 200 is powered on, the CPU 101 starts the control process shown in the flowchart of FIG.

  The display unit 201 displays an image of the virtual space including the character from the initial position of the viewpoint on the screen (step S101).

  For example, if the initial position of the viewpoint is the position of the virtual camera 701 (FIG. 5), the display unit 201 displays, for example, the image shown in FIG. 6 on the screen.

  Next, the CPU 101 determines whether the current time is the time to move the viewpoint (hereinafter referred to as “viewpoint movement time”), the time before the viewpoint movement time, or the time after the viewpoint movement time. Judgment is made (step S102).

  When the CPU 101 determines that the current time is a time before the viewpoint movement time (step S102; before the viewpoint movement time), the label unit 203 determines whether or not it is a first time before the viewpoint movement time. (Step S103).

  When it is determined that the sign unit 203 is the first time before (step S103; Yes), the sign unit 203 places the sign at the sign position in the virtual space (step S104).

  Information on the image on which the sign is arranged by the sign unit 203 is stored in a frame memory or the like included in the image processing unit 107. The image processing unit 107 waits for clearing the queue or performing another process until a vertical synchronization interrupt occurs (step S105).

  When a vertical synchronization interrupt occurs, the image processing unit 107 converts image information stored in the frame memory into a display signal, and the display unit 201 displays the image on a monitor connected to the information processing apparatus 100 ( Step S106).

  For example, when the sign unit 203 determines that the time is a first time (for example, 2 seconds) before the viewpoint movement time, the sign unit 203 places the sign 601 in the virtual space, and before the viewpoint is moved. Information of an image (for example, FIG. 7) in which the sign 601 is arranged is stored in the frame memory. When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 7 on the screen based on the information of the image.

  On the other hand, when the sign unit 203 determines that it is not the first time before the viewpoint movement time (step S103; No), the process proceeds to step S105.

  For example, when the time is 3 seconds before the viewpoint moving time, information on an image (for example, FIG. 6) that is an image before the viewpoint is moved and that does not have a sign is stored in the frame memory. . When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 6 on the screen based on the information of the image. Alternatively, when the time is one second before the viewpoint movement time, information on an image (for example, FIG. 7) that is an image before the viewpoint is moved and on which the sign is arranged is stored in the frame memory. . When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 7 on the screen based on the information of the image.

  When the CPU 101 determines that the current time is the viewpoint movement time (step S102; viewpoint movement time), the moving unit 202 moves the viewpoint in the virtual space (step S107). Then, the process proceeds to step S105.

  For example, when the CPU 101 determines that the current time is the viewpoint movement time, the moving unit 202 moves the virtual camera 701 to the virtual camera 702 as shown in FIG. Then, information of an image of the virtual space viewed from the virtual camera 702 (for example, FIG. 8) is stored in the frame memory. When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 8 on the screen based on the information of the image.

  When the CPU 101 determines that the current time is later than the viewpoint movement time (step S102; after the viewpoint movement time), the label unit 203 determines whether or not the second time has elapsed since the viewpoint movement time. (Step S108).

  When the sign unit 203 determines that the second time has elapsed from the viewpoint movement time (step S108; Yes), the sign unit 203 deletes the sign from the virtual space (step S109). Then, the process proceeds to step S105.

  For example, when the sign unit 203 determines that the second time (for example, 1 second) has elapsed from the viewpoint movement time, the sign unit 203 erases the sign 601 from the virtual space, and the image after the viewpoint is moved. And the information of the image (for example, FIG. 9) from which the sign 601 has been deleted is stored in the frame memory. When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 9 on the screen based on the information of the image.

  On the other hand, if it is determined that the labeling unit 203 has not passed the second time from the viewpoint movement time (step S108; No), the process proceeds to step S105.

  For example, when the time is 0.5 seconds after the viewpoint movement time, information on the image after the viewpoint has been moved and on which the sign is arranged (for example, FIG. 8) is stored in the frame memory. Is done. When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 8 on the screen based on the information of the image. Alternatively, when the time is 2 seconds after the viewpoint movement time, information on the image after the viewpoint is moved and the sign is deleted (for example, FIG. 9) is stored in the frame memory. . When the vertical synchronization interrupt occurs, the display unit 201 displays the image of FIG. 9 on the screen based on the information of the image.

  According to the present embodiment, before and after the direction in which the virtual space is projected changes, the player can grasp which direction is the direction before the change by arranging the sign at the relative position from the character. In addition, since the direction in which the virtual space is projected is changed instantaneously, it is possible to keep up with the required action in a rhythm game in which timing is important. In addition, by placing a sign at the front of the character, it is possible to prevent the movement of the character from being hidden by the sign.

  In the present embodiment, the time before the moving unit 202 moves the viewpoint is the first time before the time when the viewpoint should move, and the time when the viewpoint moves after the moving unit 202 moves the viewpoint. However, the present invention is not limited to this. For example, suppose that the moving unit 202 moves the viewpoint before the predetermined operation in order to make the predetermined operation easy to see. In this case, the time before the moving unit 202 moves the viewpoint may be when the operation immediately before the predetermined operation is started. Further, the time after the moving unit 202 moves the viewpoint may be the time when the predetermined operation is completed after the viewpoint is moved.

  For example, it is assumed that the arm 301 is moved by the movement distance 501 after the leg 303 (FIG. 6) is moved from the button 111U in front of the mat controller 400 to the center of the mat controller 400. In this case, the time before the moving unit 202 moves the viewpoint is when the leg 303 is released from the button 111U. Also, after the moving unit 202 moves the viewpoint, the time point when the arm 301 reaches the end point of the moving distance 501.

  In this embodiment, the sign position determined relative to the character is the front step of the character, but is not limited thereto. For example, as shown in FIG. 14 (before the viewpoint is moved) and FIG. 15 (after the viewpoint is moved), a sign 603 may be arranged on the front chest of the character.

  According to the present invention, it is possible to provide a game device, a game device control method, and a program suitable for making it easy to grasp the direction in the virtual space.
