DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shooting game apparatus, and more particularly to a shooting game apparatus that shoots a target on a display using a shooting device and a hit determination method thereof.

[0002]

2. Description of the Related Art Conventionally, there has been known a game apparatus which calculates a game screen in which a three-dimensional shooting object space is viewed from a viewpoint position of a virtual player and displays this on a display. ing. In this game device, each time the player shoots at a target displayed on the display, a hit determination is made based on the landing position.

However, in the conventional game apparatus, the hit determination is performed by equally treating both a stationary object and a moving object constituting a three-dimensional object space. For this reason, when trying to make an accurate hit determination, the calculation load for that becomes extremely large, and when the calculation load is reduced, the accuracy of the hit determination decreases, and the fun as a shooting game decreases. There was a problem that it would.

For example, based on a relative positional relationship between a polygon constituting a stationary object and a moving object in a three-dimensional object space and a virtual bullet fired from a shooting device, which polygon the flight line of the bullet intersects with is determined. Therefore, when the hit determination method for specifying the hit target is used, the hit determination operation is performed based on the relative positional relationship between the virtual bullet and all polygons every 1/60 second when the screen is updated. It must be made. Therefore, there is a problem that the calculation load for the hit determination becomes extremely large.

[0005] Further, data in an object space that can be viewed from the viewpoint position of the player is projected on a perspective projection surface of the viewpoint coordinate system as data for hit determination, and a hit target is determined based on the data and the impact position on the screen. In the case of using the method of performing the hit determination operation to specify, apart from the perspective projection conversion work for preparing the game screen, the work for preparing the hit determination data must be performed every 1/60 second. Therefore, there is a problem that the calculation load becomes extremely large.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and an object of the present invention is to determine a hit on a target existing in a three-dimensional shooting object space.
An object of the present invention is to provide a shooting game device that can be accurately performed with a small calculation load, and a hit determination method thereof.

[0007]

In order to achieve the above object, the invention of claim 1 calculates a game screen in which a three-dimensional shooting object space is viewed from a viewpoint position,
Image display means for displaying on a display, a shooting device for shooting on the display, a landing position detection means for detecting a landing position of the shooting on the game screen, and hit determination for a target based on the landing position. Hit discrimination means to be performed,
Wherein the hit discriminating means outputs first detection data including depth information from a predetermined viewpoint position to a hit position of the hit target for a stationary object in the object space. First detection means for performing a hit determination to perform a hit determination, and outputting a second detection data including depth information from a predetermined viewpoint position to a hit position of the hit target for a moving object in the object space. Second detecting means for performing the operation, the first and second detecting means
Based on the depth information of the detection data of, the determination means to determine the closer to the predetermined viewpoint position as a hit target,
The first detection unit is a storage unit that stores hit determination screen data composed of dot data including depth information from the predetermined viewpoint position to a stationary object in the object space, and a storage unit that corresponds to the landing position. Information detecting means for performing a hit determination for obtaining depth information of the hit target up to the impact position based on the dot data.

According to a sixth aspect of the present invention, there is provided a method for determining a hit of a shooting game apparatus which determines a hit on a target based on a landing position on a game screen as viewed from a viewpoint position in a three-dimensional shooting object space. A first step of performing a hit determination for outputting a first detection data including a depth information from a predetermined viewpoint position to a hit position of a hit target for a stationary object in the object space; A second step of performing a hit determination to output second detection data including depth information from a predetermined viewpoint position to a hit position of a hit target for the moving object, and the first and second detection data And a third step of determining, based on the depth information of the object, a point closer to the predetermined viewpoint position as a hit target. Based on a preliminary step of previously creating hit determination screen data composed of dot data including depth information from a point position to a stationary object in the object space, and a hit based on the dot data corresponding to the landing position. And detecting a depth information of the target object up to the landing position.

Here, either of the first and second steps may be performed first, but it is preferable to perform both in parallel and simultaneously in order to improve the efficiency of determination.

According to the present invention, a hit determination is performed separately for a stationary object and a moving object, so that an accurate hit determination can be performed with a small calculation load.

That is, in the present invention, a game screen in which the three-dimensional shooting object space is viewed from a predetermined viewpoint position is displayed on the display.

When the player shoots at a target while watching the game screen displayed on the display, a hit determination for the target is performed based on the impact position on the game screen.

At this time, the first detecting means outputs first detection data including depth information from a viewpoint position to a hit position of a hit target for a stationary object in the object space.

The second detection means outputs second detection data including depth information from a predetermined viewpoint position to a hit position of a hit target for a moving object in the object space.

[0015] Then, the determination means determines, based on the depth information of the first and second detection data, the one closer to the predetermined viewpoint position as the hit target.

As described above, according to the present invention, the stationary object and the moving object constituting the object space are separated from each other, and the hit judgment is performed for each of them, so that the characteristics of the stationary object and the moving object are considered. Accurate hit determination can be performed with a small calculation load.

That is, in the present invention, for a stationary object constituting the object space, dedicated hit discrimination screen data is prepared in advance and stored in the storage means.
The hit determination screen data is composed of a plurality of dot data, and each dot data represents depth information from a viewpoint position to the stationary object when a stationary object in the object space is viewed from a predetermined viewpoint position. It is structured as data that includes.

The dot data may be set in accordance with the required hit determination resolution. For example, the dot data may be set so as to correspond to each pixel of the display on a one-to-one basis, or one dot data may be set for a plurality of adjacent pixels. Further, when the impact position can be detected more accurately than each pixel unit (for example, when the impact position can be detected with an accuracy of 1/2 pixel), for example, one-half pixel is adjusted in accordance with the detection accuracy. It may be set in the ratio of the number.

The information detecting means obtains depth information of the hit target up to the landing position based on the dot data corresponding to the landing position.

In this manner, the hit determination for a stationary object is basically performed by referring to the hit determination screen data based on the impact position, so that the determination operation is extremely simple.

Further, in the present invention, hit determination for a moving object in the object space is performed completely separately from a stationary object constituting the object space. Therefore, the determination target is extremely limited. Even if the hit determination is performed based on the relative positional relationship between the virtual trajectory and the moving object in the object space, for example, the moving object in the object space may be viewed from the viewpoint. Perspective transformation on the screen of the coordinate system,
Even when making a hit determination, the calculation load is extremely reduced. Then, as a result of the hit determination for the moving object, depth information from the predetermined viewpoint position to the impact position of the hit target is output as the second detection data.

The judging means compares the depth information of the first detection data for the stationary object with the depth information of the second detection data for the moving object, and determines the one closer to the viewpoint position as the hit object. Can be determined.

As described above, according to the present invention, the object to be judged is divided into a stationary object and a moving object, as compared with the conventional hit judgment method in which the hit judgment is performed on all the objects constituting the three-dimensional object space by the same method. By adopting a configuration in which data for hit determination is prepared in advance for stationary objects,
The calculation load for hit determination can be significantly reduced, and accurate hit determination can be performed.

According to a second aspect of the present invention, in the first aspect, the dot data includes ancillary data representing a property of a stationary object, and the information detecting means corresponds to an impact position of the hit target. The detected depth information and the accompanying data are detected and output, and a landing effect adapted to the properties of a stationary object is performed.

According to a seventh aspect of the present invention, in the sixth aspect, in the preliminary step, the dot data includes ancillary data representing a property of a stationary object, and in the detecting step,
On the basis of the dot data corresponding to the landing position, depth information and additional data corresponding to the landing position of the hit target are detected and output.

Here, the additional data includes:
For example, the stationary object may be configured to include data such as a broken object, a falling object, or an explosive, or may be configured to include data indicating a type of a bounce sound. Good.

As described above, according to the present invention, by forming the dot data including the additional data representing the properties of the stationary object, it is possible to perform a landing effect suited to the properties of the stationary object using the additional data. it can. For example, for each stationary object, by configuring the dot data to include incidental data such as whether the stationary object falls down, breaks, or explodes, when the stationary object is hit, A game effect such as destroying, defeating, or exploding a stationary object can be performed.

According to a third aspect of the present invention, in the second aspect, when the first detection means lands on a predetermined stationary object, the first detection means converts dot data corresponding to the landing position for hit determination for the next and subsequent hits. The image processing apparatus further includes means for switching the included depth information to depth information of a stationary object existing in the depth of the hit target.

According to an eighth aspect of the present invention, in the seventh aspect, in the first step, when a landing is made on a predetermined stationary object, the landing data is included in dot data corresponding to the landing position for the next and subsequent hit determinations. The depth information is switched to depth information of a stationary object existing behind a hit target.

According to the present invention, when a landing is made on a predetermined stationary object, the depth information included in the dot data corresponding to the landing position for the next and subsequent hit determinations is replaced with the stationary information existing behind the hit determination object. Switch to object depth information. By doing so, for example, when a plurality of stationary objects are present before and after when viewed from the viewpoint position, the situation where the stationary object in front is destroyed and the stationary object can be seen behind it is accurately recognized,
A hit decision can be made.

At this time, it is preferable that the additional data of each dot data include data indicating whether or not the hit target disappears before and after the event of being hit. By doing so, it is possible to easily select the depth information to be used by referring to this data. Further, when such additional data cannot be used and the stationary object disappears after a predetermined event, the depth information included in the dot data is updated each time. May be.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the storage means stores the hit determination screen data for each predetermined shooting point set in a three-dimensional shooting object space. The information detection means stores the hit determination using hit determination screen data corresponding to a shooting point.

According to a ninth aspect of the present invention, in any one of the sixth to eighth aspects, in the preliminary step, the hit discrimination screen data is set for each predetermined shooting point set in a three-dimensional shooting object space. Create
In the detection step, the hit determination is performed using hit determination screen data corresponding to a shooting point.

When the shooting game is configured to shoot at predetermined shooting points while moving along a predetermined movement path in the three-dimensional game space, each shooting point is set. The hit discrimination screen data may be prepared and stored every time. In this manner, even when there are a plurality of shooting points, it is possible to accurately determine a hit at each shooting point.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the hit discrimination screen data is formed as data of an area larger than the display, and the information detecting means includes the viewpoint position and the viewpoint. Based on direction,
A hit area is determined by specifying a use area of the hit discrimination screen data.

According to a tenth aspect of the present invention, in any one of the sixth to ninth aspects, in the preliminary step, the hit discrimination screen data is formed as data of an area wider than a display. A use area of the hit determination screen data is specified based on a viewpoint position and a viewpoint direction, and the hit determination is performed.

As described above, by forming the hit discrimination screen data as data of an area wider than the display, the surrounding area of the hit discrimination screen data is changed based on the viewpoint position and the viewpoint direction in the three-dimensional object space. It is possible to make a hit judgment while doing so. Thereby, even when the player shoots at a predetermined shooting point, for example, looking up or down, or looking left and right, or shooting while moving up, down, left, right, etc., the hit determination is reduced. It can be performed accurately with a calculation load.

[0038]

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory perspective view showing the appearance of a shooting game apparatus to which the present invention is applied. In this shooting game apparatus, a display 12 is provided inside a housing 10 toward a player P. The display 12 is of a raster scanning type, and in this embodiment, a CRT is used.

A gun case 14 is provided on the front of the housing 10.
Is provided to accommodate the gun 20. The gun 20 is configured to be connected to a circuit inside the housing 10 via a cable. Housing 10
A coin insertion slot 16 is provided below, and when a player inserts a coin and presses a start button 18, a shooting game is started.

The player P can enjoy the shooting game by aiming the gun 20 at the targets displayed one after another on the game screen and operating the trigger button.

Further, in the shooting game apparatus of the present embodiment, a foot-operated input unit 30 is provided at a position connected to the lower part of the front surface of the housing 10 so that the player can operate the foot with the foot. The foot operation type input unit 30 allows the player to selectively input an attack state and a defense state by operating the pedal 32 in accordance with the progress of the game.

The game played by the game device of this embodiment is composed of all three stages, and each stage is composed of four areas. There are 4 shooting points in this area
When each point is cleared, it moves to the next shooting point and continues the game. Then, a time limit is set for each of these areas, and if all shooting points are cleared within the time limit, the area is cleared, the game can be continued in the next area, and if it cannot be cleared, the game is over.

The player has a certain number of lives, and loses one life when attacked by an enemy character which is also a target, and the game is over even if all lives are lost.

FIG. 2 shows an example of a shooting three-dimensional game space (object space) of the embodiment. At this shooting point, a wooden box 340 is shaded by a player battle position 310, and the player is in a wooden box 340. The setting is such that a shooting battle is performed with the enemy character while hiding behind the enemy character to avoid bullets.

However, since the real player is separated from the virtual three-dimensional game space where the enemy character displayed on the screen exists, the shooting player of this embodiment places the virtual player in the game space ( (It does not appear on the game screen.) By inputting the attack state and the defense state from the foot-operated input unit 30, the player operates the position of the virtual player in the attack or defense state to fight the enemy character. In the game screen, a visual field image of the virtual player is displayed.

FIG. 7 shows the principle of image synthesis of the game screen. Specifically, as shown in the figure, the polygons constituting the display object 600 are represented by a world coordinate system (XW, Y
(W, ZW) to perform an operation for placement on the game stage. Next, for each display object 600, a process of coordinate-converting a polygon constituting the display object 600 into a viewpoint coordinate system (XV, YV, ZV) based on the viewpoint 300 is performed. After that, window wing processing such as clipping processing is performed, and projection conversion processing to the screen coordinate system (XS, YS) is performed. Then, based on the obtained image information in the screen coordinate system, a scene of the three-dimensional game space viewed from the viewpoint 300 is displayed as an image on the display 12 as a game screen.

When the game is started, a screen showing a bird's-eye view of the shooting point is displayed on the game screen as a view image of the virtual player. The viewpoint 302 of the virtual player gradually moves from the bird's-eye view position where the shooting point can be seen to the player battle position 310 when a gun battle is performed.
A visual field image of the virtual player during that time is displayed. In addition,
During this movement, the non-combat state in which neither the player nor the enemy character 330 can attack is set.
Inputs from the gun 20 and the foot-operated input unit 30 are not accepted.

When the movement is completed, the virtual player 30
0 is positioned in a defensive state at the player battle position 310 behind the wooden box 340, and the battle starts.

FIGS. 3A to 3C are side views showing the positional relationship of the virtual player 300 in the virtual three-dimensional game space. FIG. 3A shows a defense state, and FIG. 3C shows an attack state. 3 (B) shows the intermediate state.

In the defense state, the virtual player 300 has a positional relationship as shown in FIG. 3A with respect to the wooden box 340, and the virtual player 3 shown in FIG.
A game screen which is a view image viewed from the viewpoint position 302 of 00 is displayed as shown in FIG.

When the battle starts, the enemy character 330, which can be seen from the gap in the wooden box, starts shooting, but if the player is instructing a defense state (a state in which the foot-operated input unit 30 is not depressed), The virtual player 300 is shown in FIG.
Since it is hidden behind a wooden box as shown in (A), it is possible to protect itself from the attack of the enemy character 330. In other words, in the defense state, the player is not attacked by the enemy character 330, but cannot attack the enemy character 330. However, there is a limit to the time given for one play,
The player has to defeat the enemy character 330 from behind a wooden box in order to aim for an opportunity for the enemy character 330 to attack. Then, when the player steps on the foot-operated input unit 30 with any foot, the virtual player 300 goes out of the shade to take an attacking posture and is positioned as shown in FIG. 3C.

At this time, the viewpoint position 3 of the virtual player 300
02 is a virtual player 30 in FIG.
The camera continuously moves from the 0 viewpoint position 302 to the viewpoint position 302 of the virtual player 300 shown in FIG. Therefore, the screen on the display is displayed so as to continuously change from the game screen shown in FIG. 4 in the defense state to the game screen shown in FIG. 5 in the attack state.

In the offensive state, the player is the enemy character 3
Although the enemy character 330 can attack the virtual player 300 from the enemy battle position 320, the virtual player 300 is configured to be damaged if hit. Therefore, in order to avoid the attack of the enemy character 330, when the player stops stepping on the foot-operated input unit 30, the defense state is established again.

As described above, in the shooting game apparatus of the present embodiment, the player can enjoy shooting in a gun battle while properly using an attack state and a defense state according to the battle situation in the game space.

FIG. 8 is a functional block diagram of a shooting game apparatus according to an embodiment of the present invention.

The shooting game device of this embodiment is
The game PCB 40 is formed so as to calculate a game screen in which moving targets having an attacking ability appear one after another in accordance with a predetermined game program, and to display it on the display 12.

The game PCB 40 is a game calculation unit 110 that calculates a three-dimensional shooting game space (object space) according to a predetermined game program.
And the game space (object space) and the viewpoint position 302
The image synthesizing unit 120 is configured to display a game screen viewed from the screen on the display 12 and an audio synthesizing unit 130 that synthesizes and outputs an audio signal according to the game development to the speaker 50.

The game calculation unit 110 of the embodiment includes a landing position detection unit 140 and a hit determination unit 160, and is configured to start a game based on a signal from the operation unit 11 such as the start button 18. I have.

When the player shoots the target with the gun 20, the impact position detection section 140 detects the impact position on the game screen. Then, when the hit determination unit 160 determines that the impact position matches the target position and determines that the bullet has hit, a screen in which the bullet hits the target is displayed as an image, and the player visually checks whether or not the target hits the target. You can enjoy it.

Next, a description will be given of a configuration in which the impact position detecting section 140 detects the impact position on the display 12 when the trigger 26 of the gun 20 is operated.

A light receiving portion is formed on the barrel of the gun 20. That is, the barrel of the gun 20 has a hollow shape, a lens 22 at the tip of the barrel, and a light receiving sensor 24 at the back.
Is provided, and the light 210 from the barrel direction is received by the light receiving sensor 24.
It is configured to detect by using.

The light receiving sensor 24 is connected to the display 12
, A detection area 200 having a diameter of about several cm is provided. When the raster scanning of the display 12 passes through the detection area 200, the light receiving sensor 24 outputs a detection pulse to the game calculation unit 110.

When the player aims at the target and operates the trigger 26, the trigger signal is transmitted to the game operation unit 1
Then, the game calculation unit 110 sends flash screen data so that the image synthesis unit 120 flashes the display 12 for position detection at the next inter. The light receiving sensor 24 outputs a detection pulse when the raster scanning on the display 12 is performed with a light amount equal to or more than a certain amount. Since the landing position detection unit 140 performs the position calculation in response to the detection pulse, when the display 12 is flashed for position detection, when the flash screen is displayed, the landing position detection unit 140 detects the light from the light receiving sensor 24. Based on the horizontal and vertical raster scanning positions at the time of pulse input, X and Y coordinates representing the landing position on the screen are detected.

The hit judging section 160 judges whether or not the landing position matches the hit area of the target, and performs a game effect for hitting or a game effect for missing.

The hit judging section 160 of this embodiment performs such a hit judgment separately for a stationary object and a moving object constituting the game space, and makes a final hit judgment based on each hit judgment result. Is configured. As a result, the load of hit determination can be significantly reduced without lowering the accuracy of hit determination.

Hereinafter, the configuration for performing the hit determination will be described in detail.

FIG. 9 is a specific functional block diagram of the hit judging section 160 of the embodiment, and FIG. 10 is a flowchart showing the operation thereof.

When the game is started, the impact position detecting section 140 determines whether or not there is a shooting operation by the player until the game ends, and when the shooting operation is performed, the impact position is determined as described above. Is detected (steps S10, S12, S14).

The hit determination unit 160 performs a hit determination on a stationary object in the game space, and outputs the determination result as first detection data (step S16). The unit 170 performs a hit determination on a moving object in the game space, and outputs the determination result as second detection data (step S1).
8) Moving object hit check section 180 configured as above
And the hit target is specified based on the first and second detection data, and the determination result is output (step S2).
0) and a final determination unit 190 configured as described above.

Each of the hit check sections 170 and 180
Is configured to output data including depth information (Zv-axis information in the viewpoint coordinate system) from the viewpoint position to the impact position of the hit target. That is, when a stationary object and a moving object are present at the landing position, depth information (Zv axis information) of the stationary object at the landing position is used as the first detection data.
Is output, and the depth information (Zv-axis information) of the moving object at the landing position is output as the second detection data.

The depth information does not need to be the Zv axis information itself in the viewpoint coordinate system, and it is possible to determine which of the landing positions of the stationary object and the moving object is closer to the front along the Zv axis in the viewpoint coordinate system. Information is fine. For example, it may be divided into several zones along the Zv axis of the viewpoint coordinate system, and which zone each landing position belongs to may be used as depth information.

The final determination section 190 determines whether the first and second
Based on the depth information of the detected data, the object closer to the viewpoint is determined and output as the hit object.

In the present embodiment, the hit check unit 170 for the stationary object stores the hit check table memory 17.
2 and an information detection updating unit 174.

The table memory 172 stores hit determination screen data at each shooting point described above. The hit discrimination screen data is formed so as to correspond one-to-one with the game screen displayed on the display, and includes a plurality of dot data corresponding to each pixel on the display.

That is, when the virtual player is in an attacking state at each shooting point, when a stationary object in the game space is viewed from the viewpoint position, the distance between the viewpoint position and each stationary object (Zv axis information) Each of the dot data is prepared in advance as data including.

The information detecting / updating unit 174 stores the table memory 17 based on the impact position on the display.
2, the dot data of the corresponding pixel is read out, and this dot data is used as the first detection data in the final determination section 190.
Output to

In this way, a hit determination on a stationary object constituting the game space can be accurately performed with a small number of calculations.

In particular, in this embodiment, the viewpoint position and direction of the player in the attack state at each shooting point are fixed. Therefore, the hit determination screen data may be formed so as to coincide with the area of the game screen displayed on the display, thereby reducing the data amount of the hit determination screen data prepared for each shooting point. can do.

The moving object hit check unit 180
Each time a landing position is detected, a hit determination is performed on a moving object existing in the game space, in this embodiment, the enemy character 330, and the determination result is output as the above-described second detection data. If there is no moving object at the landing position, the data of the loss is output as the second detection data.

The hit judgment on the moving object can be made by using various methods as needed. For example, a trajectory position in the three-dimensional game space is calculated from a landing position on the display, and a landing position in the game space is specified based on a relative position between the trajectory position and the moving display object. Then, depth information obtained by viewing the landing position from the viewpoint position may be output as second detection data.

Further, the moving display object in the game space may be perspectively transformed on the projection plane, and the second detection data may be calculated and output using the depth information included in the transformed data.

In the conventional detection method, such a hit discrimination operation for a moving display object is performed not only for a moving object but also for all display objects including a stationary object. Performing such a hit discrimination in synchronization with the screen update every 1/60 second places an excessive burden on the CPU. In contrast,
In the present embodiment, the hit determination using the conventional method may be performed only for the moving display object. In the present embodiment, in particular, only the enemy character 330 moves among the display objects constituting the game space. Since it becomes a display object, the amount of calculation can be greatly reduced.

When the outlier data is output as the second detection data, final determination section 190 outputs the first detection data as hit check data. If the second detection data is not outlier data, the depth information included in the first and second detection data is compared, and data having a small depth information (data representing a display object close to the viewpoint position) is selected. , And outputs the detected data as hit check data. That is, when the bullet shot by the player hits the enemy character 330, whether or not there is a stationary object serving as an obstacle in front of the enemy character 330 is output from the static object hit check unit 170. 1
Is determined based on the depth information of the detected data. And
If there is no stationary object in the foreground, second detection data indicating that the shot bullet hits the enemy character 330 is selectively output from the final determination unit 190. For example, as shown in FIG. 3C, the moving object (the enemy character 330
If there is an obstacle 344 such as a wall in front of a),
First detection data indicating that the shot has hit an obstacle is selectively output from the final determination unit 190. Further, when the shot bullet does not hit the enemy character 330 and a miss is output as the second detection data, the first detection data indicating that the shot hit a stationary object is selectively output as it is. Become.

FIG. 6 shows a specific configuration of each dot data stored in the table memory 172. Each dot data has 12 bits of depth information (Zv
Axis information) and 4-bit accompanying data.

The accompanying data is configured as data representing the properties of a stationary object. For example, the information includes information such as whether the stationary object is broken, falls, explodes, or the like. It also includes data that specifies the sound of a moving object. Further, if necessary, before and after the event (the bullet), it may be formed so as to include data indicating that the impact position and the stationary object around it disappear. In this case, when the event occurs, based on this data,
The depth data included in the dot data is used by switching to new data for subsequent hit determination. That is, when an event occurs and the hit determination is completed, the depth data of the dot data is switched to the depth data of a stationary object existing behind the hit target and used thereafter. In this case, the data switching may be performed programmatically by the updating unit 174 with reference to the accompanying data, and the depth data included in the dot data stored in the table memory 172 may be updated each time. It may be.

As described above, by configuring the dot data stored in the table memory 172 so as to include the accompanying data, the first detection data selectively output from the final determination unit 190 includes the accompanying data. become. For this reason, it is possible to perform a landing effect in accordance with the properties of the stationary object, and to reflect the effect on the game screen on the display and the audio output output from the speaker (step S22).

The present invention is not limited to the above-described embodiment, but can be modified within the scope of the present invention.

FIG. 11 shows another example of the present invention. In the game device of the embodiment, the hit determination screen data is created and stored in accordance with the size of the game screen at each shooting point.
