Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a video game device capable of executing a so-called 3D game in which a virtual three-dimensional space is projected on a display screen of a display device, and a program for controlling the video game device. It relates to a recording medium.

[0002]

2. Description of the Related Art In recent years, a so-called 3D game in which a virtual three-dimensional space is projected on a display screen of a display device has been actively developed, and is gaining popularity among players.

[0003] Among such 3D games, in a game in which a player character attacks or acquires an enemy character or an item, etc., the game progresses, it is difficult for the player character to find the enemy character or an item. Naturally necessary for progress.

However, in a virtual three-dimensional space, an investigation target, such as an enemy character or an item, exists at a position behind, behind, up, down, left or right of the player character, and the investigation target is in the field of view of the player character. If not, the player character cannot find the investigation target.

[0005] For this reason, in the conventional 3D game, the survey target is arranged within the field of view of the player character. As a result, the degree of freedom in game production is reduced, and the free idea of the game creator is restricted, which may hinder the surprisingness of the game and maximize the interest of the player. There was a problem that it was not possible to provide a game that caused the game to run.

Therefore, in a 3D game in which at least a part of the player object is projected on the display screen of the display device, when a specific operation button is operated by the player, the player object is moved to the non-player in the three-dimensional virtual space. 2. Description of the Related Art There has been proposed a video game apparatus in which an image of a player object is displayed on a display screen of a display device from an obliquely rear side of the player object (see JP-A-11-128533).

However, in such a conventional video game device, at least a part of the player object is projected on the display screen of the display device when the player object faces the non-player object. When employed in a game, the player has a problem that the player object on the display screen becomes an obstacle, and the interest of the game is reduced. That is, in a scene where the player object aims at the non-player object and shoots, the player's own emotion is the player object, and when the player object is projected on the display screen, the player himself becomes virtual. This impairs the empathy of being faced with the non-player object in the three-dimensional space, or even hinders the shooting, and rather impairs the interest of the game.

[0008]

That is, image data of a three-dimensional object such as a character is processed by a CPU 5 having a function as a geometry engine and a rendering engine, and a RAM 6 having a function as a frame buffer.
The signal is supplied to the composite video signal generation circuit 10 via the interface circuit 8. As a result, the composite video signal generation circuit 10 generates a composite video signal for driving the display device 2 based on the image data from the CPU 5 and supplies it to the display device 2. Thus, an image for one frame or one field is displayed on the display screen of the display device 2. By repeating such processing every 1/30 seconds or 1/60 seconds, a moving image of the 3D shooting game is displayed on the display screen of the display device 2.

Further, the CPU 5 generates sound data such as voice guidance, music, and sound effects of the game in conformity with the display contents on the display screen of the display device 2.
The sound data is supplied to the sound signal generation circuit 9 via the interface circuit 8. Thereby, the sound signal generation circuit 9 generates a sound signal based on the sound data, and drives the speaker 3 with the sound signal.

On the other hand, when the gun-type controller 4 is operated by the player, an operation signal corresponding to the operation content is supplied from the gun-type controller 4 to the CPU 5 via the interface circuit 8. That is, when the player pulls the trigger 21, the trigger switch 14 is turned on. When the player presses the first push button 22, the first push button switch 15 is turned on. When the player presses the second push button 23, the second push button switch is turned on. Since 16 is turned on, each operation signal is supplied to the CPU 5. When the player points the muzzle 25 of the gun-type controller 4 to the display screen of the display device 2, the display device 2
The light emitted from the display screen is detected by the photo sensor 13 and the photo sensor 13 is turned on, so that a detection signal from the photo sensor 13 is supplied to the CPU 5 via the interface circuit 8. The CPU 5 monitors the operation signal from the gun-type controller 4, analyzes the meaning of the operation signal by using the determination result, and executes processing such as changing the progress of the game based on the analysis result. .
Further, the CPU 5 operates the trigger 21 of the gun-type controller 4.
Then, the aiming position at the time when is drawn is determined, and whether or not an enemy character is present at the aiming position on the display screen of the display device 2 is determined, and a hit or miss process is performed.

That is, the CPU 5 and the composite video signal generation circuit 10 constitute video signal generation means for generating a video signal for displaying a moving image on the display screen of the display device.

The gun-type controller 4 has a plurality of operation units, and constitutes operation means for outputting an operation signal according to an operation of the operation unit by the player.

The CPU 5 operates based on a video game program, and controls the video signal generation means in response to an operation signal from the operation means, thereby displaying a video of the game on the display screen of the display device. Control means are realized.

The first push button 22 constitutes an operation unit for moving a viewpoint for moving to an investigation object which is not currently in the field of view of the player character.

The second push button 23 constitutes a reset operation section for returning the viewpoint of the player character from the survey target to the normal viewpoint.

The ROM 7 has a display device having a display screen, a video signal generating means for generating a video signal for displaying a moving image on the display screen of the display device, and a plurality of operation units.

A recording medium is stored which stores a program including a viewpoint moving program for moving the viewpoint of the player character to a research target not currently in the field of view of the player character.

FIG. 4 is a flow chart for explaining the procedure of the trigger processing by the CPU 5. Referring to this flow chart, a change in the progress of the game when the player operates the trigger 21 of the gun-type controller 4 will be described. I do. Note that the trigger processing belongs to the main routine, and is executed not every fixed time but every sufficiently short time as compared with the time when the trigger 21 of the gun-type controller 4 is operated by the player.

First, the CPU 5 determines whether or not the trigger switch 14 is turned on (S1). That is, it is determined whether or not the player has pulled the trigger 21 of the gun-type controller 4.

If the trigger switch 14 is on (S
1: YES), the CPU 5 determines whether or not the photo sensor 13 is on (S2). That is, if the player is aiming the gun-type controller 4 at the display screen of the display device 2, the light emitted from the display screen turns on the photosensor 13, so that the player displays the muzzle 25 of the gun-type controller 4 on the display screen. Find out if you're going to. The determination as to whether or not the photo sensor 13 is on is continued for a time of, for example, about 1/30 second or 1/60 second. That is, a raster for projecting an image on the display screen of the display device 2 scans one screen in 1/30 second when not using interlaced scanning, and 1/60 second when employing interlaced scanning. To determine whether or not the aiming position of the gun-type controller 4 exists on the display screen, such a time is required. If there is a possibility that it is difficult to distinguish between light emitted from the display screen and light emitted from indoor lighting fixtures or the like, the display screen of the display device 2 is displayed at the moment when the player operates the trigger 21. May be configured to flash to maximize brightness.

If the photo sensor 13 is on (S2:
YES), the CPU 5 determines the aiming position of the gun-type controller 4 (S3). That is, when the player pulls the trigger 21 of the gun-type controller 4, it is checked which position on the display screen of the display device 2 the muzzle 25 is facing.

The aiming position on the display screen of the display device 2 is determined, for example, when the photo sensor 13 is turned on while the trigger switch 14 is on, the vertical counter 11 and the horizontal counter 12 of the composite video signal generating circuit 10 are turned on. This can be realized by reading the count value. Since the principle is well known, the detailed description is omitted. However, the count value of the vertical counter 11 indicates the vertical raster position of the display screen, and the count value of the horizontal counter 12 indicates the horizontal raster position of the display screen. Therefore, the position of the raster at which the photo sensor 13 is turned on can be known from these count values. Since the position of this raster is the position where the muzzle 25 of the gun-type controller 4 is directed, that is, the aiming position, the aiming position can be determined.

Then, the CPU 5 determines whether or not an enemy character exists at the aiming position (S4). That is, it is determined whether or not the trigger 21 has been pulled with the muzzle 25 facing the enemy character.

If an enemy character is present at the aiming position (S4: YES), the CPU 5 executes a hitting process (S5) and terminates this routine. The hit processing is
This processing is performed when a bullet or the like hits an enemy character by shooting. For example, a moving image of the enemy character being shot and falling is displayed on the display screen of the display device 2.

In step S4, if no enemy character exists at the aiming position (S4: NO), the CPU 5
However, it performs a missing process (S6) and terminates this routine. The miss processing is processing when a bullet or the like does not hit an enemy character due to shooting, for example,
The number of bullets filled in the gun of the player character is reduced.

In step S2, if the photo sensor 13 is not turned on (S2: NO), it means that the aim of the gun type controller 4 has deviated from the display screen of the display device 2, and the process proceeds to step S6. Of course, when the trigger 21 is pulled in a state where the aim of the gun-type controller 4 is out of the display screen of the display device 2, the routine may be ended without executing the out-of-process.

In step S1, the trigger switch 1
If the switch 4 is not turned on (S1: NO), it means that the trigger 21 has not been pulled, so this routine ends.

FIG. 5 is a flow chart for explaining the procedure of the push button processing by the CPU 5. Referring to this flow chart, the game when the player operates the first push button 22 or the second push button 23 of the gun type controller 4 will be described. The change of the progress status will be described. Note that the push button processing belongs to the main routine, and is not performed at regular time intervals, but for a sufficiently short time as compared with the time when the first push button 22 or the second push button 23 of the gun-type controller 4 is operated by the player. It is executed every time.

First, the CPU 5 determines whether or not the first push button switch 15 is turned on (S11). That is,
It is checked whether or not the player has pressed the first push button 22 of the gun-type controller 4.

If the first push button switch 15 is turned on (S11: YES), the CPU 5 determines whether or not the survey target exists at a position outside the field of view of the player character (S12).

Now, as shown in FIG. 6, a player character 32 is placed inside a room 31 forming a virtual three-dimensional space.
, An enemy character 33 and an item 34, and a door 35 is provided in the room 31. Then, it is assumed that the player character 32 faces the direction of the door 35 and an image as shown in FIG. 7 is projected on the display screen of the display device 2. The viewpoint of the player character 32 in this state is set as a normal viewpoint.
In this normal viewpoint, the enemy character 33 that is the object to be investigated is
Since the item and the item 34 are not in the field of view of the player character 32, the survey target exists at a position not in the field of view of the player character.

If the object to be investigated exists at a position outside the field of view of the player character (S12: YES), C
The PU 5 moves the viewpoint of the player character 32 to the research object having the highest priority (S13). Here, the priority of the enemy character 33 is set to first and the priority of the item 34 is set to second, so that the viewpoint of the player character 32 moves to the enemy character 33 and the display screen of the display device 2 Displays an image as shown in FIG. Therefore, the player character 32 can find the enemy character 33 that has not been in the field of view so far, and can aim and attack the enemy character 33 as shown in FIG. In addition, the name of the survey target that is not in the field of view of the player character 32,
The priority order is stored in the RAM 6 according to the situation of the scene in the process in which the CPU 5 reads the program stored in the ROM 7 into the RAM 6 and advances the game.

Then, the CPU 5 deletes the priority order of the survey target subject to the viewpoint movement (S14), and terminates this routine. That is, the priority of the enemy character 33 is deleted from the RAM 6. This is because the viewpoint of the player character 32 moves to the item 34 as shown in FIG. 9 the next time the player presses the first push button 22. Of course, instead of deleting the priority, the flag may be turned on or off.

In step S12, if there is no survey object at a position not in the field of view of the player character (S12: YES), the CPU 5 returns the viewpoint of the player character 32 to the normal viewpoint (S15). End the routine.

In step S11, if the first push button switch 15 is not turned on (S11: NO), the CPU
5 determines whether the second push button switch 16 is on (S16). That is, it is determined whether or not the player has pressed the second push button 23 of the gun-type controller 4.

If the second push button switch 16 is turned on (S16: YES), it means that the second push button 23 as the reset operation section has been pressed, so that step S
Proceed to 15.

If the second push button switch 16 has not been turned on (S16: NO), it means that both the first push button 22 and the second push button 23 have not been pressed, and this routine ends.

Thus, every time the player presses the first push button 22, the image projected on the display screen of the display device 2 is
The state shown in FIG. 7, the state shown in FIG. 8, and the state shown in FIG. 9 are cyclically switched. When the image projected on the display screen of the display device 2 is in the state shown in FIG. 8 or FIG.
Pressing 3 switches to the state shown in FIG. of course,
If the player character 32 attacks and defeats the enemy character 33 or obtains the item 34, the player character 32 or the enemy character 33 does not exist. Therefore, even if the first push button 22 is pressed, the player character 3
The second viewpoint remains the normal viewpoint.

As described above, not only the whole body of the player character 32 but also a part of the player character 32 is not displayed on the display screen of the display device 2 as a moving image of the game. In a scene such as shooting with an aim, impairment of empathy that the player himself is facing the enemy character 33 in the virtual three-dimensional space,
Furthermore, it does not interfere with shooting. In addition, when the player operates the first push button 22, the viewpoint of the player character 32 is moved to an investigation target such as the enemy character 33 or the item 34 which is not currently in the field of view of the player character 32. There is no such thing as reducing the degree and restricting the free idea of the game creator and hindering the unexpectedness of the game. As a result, it is possible to maximize the interest of the player.

Further, since the gun-type controller 4 is provided with the second push button 23 for resetting, the player can easily return the viewpoint of the player character 32 to the normal viewpoint whenever necessary. This is particularly useful when there are an extremely large number of investigation objects that are not in the field of view of the player character 32.

In the above embodiment, every time the player presses the first push button 22 of the gun-type controller 4, the viewpoint of the player character 32 is changed to the enemy character 33.
Or the item 34, but the gun-type controller 4 is provided with a push button for each type of object to be investigated. For example, different push buttons are used for moving the viewpoint to the enemy character 33 and for moving the viewpoint to the item 34. May be configured to be pressed.

Although the operation for moving or turning the player character 32 has not been described in the above embodiment, for example, the player character 32 is quickly pressed twice by pressing the first push button 22 twice.
The player character 32 retreats by continuously pressing the first push button 22 for a predetermined time, and the player character 32 quickly presses the second push button 23 twice.
The player character 32 may turn left by continuing to press the second push button 23 for a predetermined time. Needless to say, the player character 32 is not displayed on the display screen of the display device 2 during the movement or turning of the player character 32, and an image reflected in the field of view of the player character 32 is displayed on the display screen of the display device 2.
Note that a push button different from the first push button 22 and the second push button 23 may be provided on the gun-type controller 4 to move or turn the player character 32.

In the above-described embodiment, the gun-type controller 4 is provided as the operating means. However, other controllers may be provided as the operating means.

In the above embodiment, the case where a so-called shooting game is executed has been described. However, the present invention can of course be applied to a case where another 3D game is executed.
