(Outline of Shooting Game) An outline of the shooting game of the present embodiment will be described with reference to FIGS.
As shown in FIG. 3, the scene of the shooting game is displayed on the screen of the shooting game. A part of the gun 20 holding the character is displayed on the screen, and the gun 20 is displayed in the scenery.
Is displayed.

The character is a joystick 11a
Is operated by the trackball 11b. As shown in FIG. 4, the moving direction of the character is instructed by the joystick 11a. When the joystick 11a is moved backward, the character moves forward, and when the joystick 11a is moved forward, the character moves backward, and the joystick 1
When the character 1a is tilted left, the character runs left, and when the joystick 11a is tilted right, the character runs right.

The direction of the character is indicated by the trackball 11b. As shown in FIG. 5, when the trackball 11b is turned backward, the character faces upward, the aim is upward, and the camera is upward. When the trackball 11b is turned to the front, the character faces down, the aim is down,
The camera faces down. When the trackball 11b is turned to the left, the character turns left and turns left, the aim turns left, and the camera turns left. When the trackball 11b is turned right, the character turns right and turns right, the aim turns right, and the camera turns right.

The player operates the joystick 11a and the trackball 11b to move the character, and controls the direction of the character to turn the character in any direction. The character is facing the gun 20
, And a sighting frame 22 is displayed in front of it.

When the bullet is fired by pressing the operation button 11e, the bullet flies toward the center of the aiming frame 22. If the target object such as the enemy character is stopped, the target object is captured in the aiming frame 22 and can be hit by hitting the target.

When an object such as an enemy character is moving, the position where the object is predicted to be present when a bullet arrives is determined in consideration of the moving direction, speed, and distance of the object. You need to aim and fire a bullet. A player's skill is to accurately predict the position of such an object and shoot. It is also an important skill to move the character when the enemy fires a bullet so that the enemy performs a movement contrary to the prediction of the opponent player. Players compete for such skills and enjoy shooting games.

(Beginner Mode) In the shooting game described above, the movement and direction of the character can be freely controlled by making full use of the joystick 11a and the trackball 11b, and sometimes the character can be jumped up using the jump button 11c. It is possible, and the degree of freedom of operation by the player is high, so that advanced operation is possible. However, since there is too much freedom in operation, the operation is very difficult for a beginner, and the character cannot be operated as desired.

For this reason, in this embodiment, a beginner's mode, ie, a beginner's auto aiming mode, is provided to compensate for the lack of skill of a beginner and to make it easier to hit a target.

In the beginner mode of the present embodiment, the following is performed so that the operation can be performed more easily.

First, the aiming frame is enlarged. FIG.
As shown in the figure, a vertically long frame 2 is formed so as to be entirely larger than the original aiming frame 22 so as to include the entire enemy character.
It is set to 4.

Second, when the bullet is fired, the aiming frame 24
If there is an enemy character 26 within the enemy character, the firing angle is corrected to make it easier to hit. This correction control will be described with reference to the flowchart in FIG. 7 and the display screen example in FIG.

First, the player operates the joystick 11a.
It is assumed that the operation button 11e is pressed and the trigger is pulled (step S10). Next, it is determined whether there is an enemy character in the field of view shown in FIG. 8 (step S11). If the enemy character is not in the field of view, a bullet is fired toward the center of the aiming frame 24 as usual (step S1).
6).

If there are a plurality of enemy characters in the field of view, the enemy character closest to the center of the aiming frame 24 is set as the shooting target (step S12). If there is only one enemy character in the field of view, that enemy character is the target. In the example of the display screen of FIG. 8, the enemy character 26 is the target.

Next, it is determined whether or not the object is within the aiming frame 24 (step S13). Object is aiming frame 2
If not, the bullet is fired toward the center of the aiming frame 24 as usual (step S16).

When the object is within the aiming frame 24,
An angle correction value is calculated from the position, the moving speed, the moving direction of the object, the own position, and the speed of the bullet so as to hit the “expected position of the object when the bullet arrives” (step S1).
4). Subsequently, a bullet whose angle has been corrected is fired in the calculated direction (step S15).

This angle correction is a correction to hit the enemy character if the state at the time when the player pulls the trigger does not change as it is. If the player is a skilled player, he or she will fire a bullet after predicting that fact, and the game apparatus will automatically correct this. After the player triggers, the moving enemy character stops moving,
If the state changes by changing the moving direction, etc.,
The bullet does not hit the enemy character, and the enemy character can escape from the bullet.

Next, a specific example of calculation of the angle correction will be described. The XYZ coordinates of the position of the enemy character are (px0,
py0, pz0), the XYZ speed of the enemy character is (vx, vy, vz), the XYZ coordinates of the own position are (px1, py1, pz1), and the magnitude of the bullet speed of the weapon being used is v And X at the intersection of the bullet and the enemy character
The YZ coordinates are (px, py, pz), and the intersection time is t. Enemy character is position (px0, py0, pz0)
From (sx, sy, sz).

The equation of the intersection and the straight line in the direction of movement of the enemy character is: (px-px0) / vx = (py-py0) / vy = (p
y-py0) / vy = t. Therefore, the following equation is satisfied: px = px0 + (vx × t) py = py0 + (vy × t) pz = pz0 + (vz × t)

The equation of the intersection, the position of oneself, and the velocity of the bullet is given by √ ((px-px1) 2+ (py-py1) 2+ (pz-pz
1) 2) = v × t

When these equations are expanded by t, a quadratic equation for t is obtained. The solution of this quadratic equation is t = (− b ± √ (b2-4ac) / 2a, where a = vx2 + vy2 + vz2 b = 2 (px0 × vx + py0 × vy + pz0 × vz−px1 × vx−py1 × vy
−pz1 × vz) c = px02 + py02 + pz02-2 (px0 × px1 + py0 × py1 + p
z0 × pz1).

The coordinates (px, py, pz) of the intersection are calculated from the intersection time t thus obtained. The coordinates (px, py, pz) of the intersection and the own position (px1, py
1, pz1), the firing angle of the bullet is calculated.

When the enemy character is moving quickly or shooting an enemy in a short distance, the correction angle obtained by the above calculation may be significantly different from the angle to which the player is facing, and may be unnatural. If the bullet is fired at the angle corrected by the calculation as it is, the bullet may be fired right next to or after itself. Since this is unnatural, the firing angle is limited so that the bullet is fired only in front of the player.

Third, when an enemy character 26 as an object enters the aiming frame 24, the sensitivity of the trackball 11b is reduced. Thus, once an enemy is captured in the aiming frame 24, the careless operation of the trackball 11b makes it difficult for the enemy character 26 to easily come off the aiming frame 24. It is desirable to lower the sensitivity by about 5% to 90% as compared with the sensitivity when no object is in the aiming frame 24.

Regarding this trackball sensitivity correction,
This will be described with reference to the flowchart of FIG. First, it is determined whether there is an enemy character in the field of view (step S2).
0). If the enemy character is not in the field of view, the moving amount of the aim (character direction) based on the moving amount (rotation speed) of the trackball 11b does not change as usual (step S24).

When there are a plurality of enemy characters in the field of view, the enemy character closest to the center of the aiming frame 24 is set as the shooting target (step S21). If there is only one enemy character in the field of view, that enemy character is the target. In the example of the display screen of FIG. 8, the enemy character 26 is the target.

Next, it is determined whether or not the object is within the aiming frame 24 (step S22). Object is aiming frame 2
If it is not within the range 4, the amount of movement of the aim (character direction) by the amount of movement (number of rotations) of the trackball 11b does not change as usual (step S24).

When the object is within the aiming frame 24,
The moving amount of the aim (the direction of the character) based on the moving amount (the number of rotations) of the trackball 11b is made smaller than usual (step S23).

As described above, when the enemy character is within the aiming frame 24, the sensitivity of the trackball 11b is reduced so that the trackball 11b is not easily removed from the aiming frame 24 even if the trackball 11b is carelessly operated. I have to.

As a method of detecting the operation amount of the trackball 11b, the number of rotations of the trackball 11b may be detected, or the rotation speed of the trackball 11b may be detected.

Fourthly, the movement of the trackball 11b in the vertical direction is restricted. Moving the character's viewing angle upwards will see the sky, and moving it downwards will see the ground. For beginners, there is little discomfort in moving left and right viewing angles, but strong discomfort is seen in moving up and down viewing angles. Moreover, there is less need to fire at the sky or at the ground. Therefore, restrictions are placed on the movement of the vertical viewing angle. Specifically, the operation can be performed up to a range of ± 22.5 degrees with respect to the horizontal plane, but the visual movement is not performed any more. In the ordinary expert mode, the range with respect to the horizontal plane is from ± 45 degrees to ± 6 degrees.
Visually move within a range of 7.5 degrees.

Fifth, during the movement of the character, the vertical viewing angle is forcibly set toward the ground. As described above, for a beginner, there is a sense of discomfort in moving the visual angle up and down, but maintaining the visual angle in the up and down direction during movement is more uncomfortable.
It is difficult to intuitively move while looking up or down. Therefore, when the character is moved by operating the joystick 11a, the vertical viewing angle is automatically reset to a direction that matches the inclination of the moving ground. That is, on a horizontal ground, the direction is horizontal, but on a slope, the direction matches the angle of the slope. This means that when you move, you ’ll always point along the moving ground,
Subsequent viewing angle operations can also be easily performed.

(Display of Smoke Image by Plate Polygon)
A method of displaying an image of smoke using a plate polygon will be described with reference to FIGS.

In a 3D game that draws in real time, in order to express effects such as smoke, water, flame, and spark, an expression method using a plurality of plate polygons obtained by pasting a texture on a plate polygon is often used. I have. This is because considering the performance of hardware, the number of polygons per effect can be reduced, and the amount of data and the time required for drawing can be reduced, so that the power of hardware can be saved.

However, when expressing an effect that is long connected from any direction, such as smoke from a rocket, a small number of plate polygons do not appear to be connected depending on the direction. For this reason, smoke is drawn by using a large number of plate polygons using a large amount of hardware power or a polygon model using many polygons, or the smoke is cut off by a small number of plate polygons by saving hardware power. I have no choice but to draw.

The present embodiment provides a method for expressing connected smoke by using a small number of plate polygons from any direction. As a result, the connected smoke can be expressed clearly from any direction while saving the power of the hardware.

FIG. 10 shows a plate polygon showing a smoke object. As shown in FIG. 10A, the plate polygon 30 has, for example, a square outer shape, and a smoke texture 32 is affixed thereto. The plate polygon 30 is
As shown in FIG. 10 (b), they are arranged at the designated coordinates of the global coordinates in the designated direction.

FIG. 11 shows a conventional method for displaying an image of smoke.
This will be described with reference to FIG. The conventional smoke image display method includes three steps. In the first step, a position P on the trajectory of the bullet just before the smoke comes out and where the smoke is displayed is set (FIG. 11A). In the next second step, the center of the plate polygon 30 is set at the set position P where smoke appears (FIG. 1).
1 (b)). In the next third step, the plate polygon 30 is rotated so as to face the camera viewed by the player (FIG. 11C).

The smoke expressed by such a conventional method is as shown in FIG. When expressing the smoke of the high-speed rocket 40, the installation intervals of the plate polygons 30 are widened, and as shown in FIG.

A method for displaying an image of smoke using plate polygons according to the present embodiment will be described with reference to FIG. The smoke image display method according to the present embodiment includes five steps. In the first step, a position P on the trajectory of the bullet just before the smoke comes out and where the image is displayed is set (FIG. 12).
(A)). In the next second step, the setting position P where smoke appears
Is set to the center of the plate polygon 30 (FIG. 12).
(B)).

In the next third step, the plate polygon 30 is rotated to match the direction of the trajectory of the bullet with the direction of the Z axis of the plate polygon 30 (FIG. 12 (c)). By applying a scale proportional to the speed of the bullet in the direction of the Z-axis of the polygon 30, a prismatic display virtual frame 34 terminated by plate-like end surfaces 34a and 34b is set (FIG. 12D). .

In the next fifth step, the plate polygon 30 is rotated so that the plate polygon 3 is rotated in the rectangular display virtual frame 34.
0 is directed to the direction of the camera, that is, the direction of the viewpoint (FIG. 12 (e)). Thereby, the plate polygon is expanded and contracted so as to be maximum in the display direction.

The smoke expressed by the image display method of this embodiment is as shown in FIG. When expressing the smoke of the high-speed rocket 40, even if the intervals between the plate polygons 30 are widened, as shown in FIG. Will be displayed as

As described above, according to this embodiment, the polygons are calculated in real time using the plate polygons, and the polygons are arranged along the moving direction, and are expanded and contracted so as to be maximized when viewed from the display direction. Even if displayed from the direction, it is possible to display the movement trajectory of naturally connected smoke and the like.

(Game Continuation End Method) Next, a game continuation end method will be described with reference to FIG. 14 and FIG.

In the conventional game continuation ending method, a continuation screen for displaying “continue” or the like is displayed for a certain period of time after the game is over, and when a coin is inserted during that time, the game continuation processing is performed. If there is no insertion, the game is over. The player determines whether or not to continue the game while the continuable screen is displayed.

In recent years, competitive games have become popular, and among them, competitive games in which several players participate. After such a fighting game is over, despite the fact that all players are willing to continue, but one of the players is not ready for coins, etc. In some cases, they could not participate in subsequent games.

On the other hand, when the player is ready, there is also a demand that the player wants to make the display of the continuation possible screen as short as possible and restart the game as soon as possible.

The game continuation ending method according to the present embodiment is as follows.
The display time of the continuation screen can be shortened or lengthened by the player's button operation.
The game continuation ending method according to the present embodiment will be described with reference to the flowchart in FIG. 14 and the display screen example in FIG.

When the game is over, the continuation possible screen is displayed as shown in FIG. 15B through the display of the game over screen (step S30) shown in FIG. 15A, and a continuation timer (not shown). ) Is set to an initial value, for example, 10 seconds (step S31). On the continuation possible screen, for example, "Continue ..." is displayed, and below that, the remaining number of continuation timers, which is the display time of the continuation possible screen, is displayed in seconds. FIG. 15B shows that the continuation time is 10 seconds.

Next, it is determined whether or not the operation button has been pressed (step S32). If the operation button has not been pressed, it is determined whether one second has elapsed (step S33). If one second has elapsed, one second is subtracted from the continuation timer (step S34). If one second has not elapsed, the process returns to step S32.

Next, it is determined whether or not the continuation timer has expired (step S35). If the continuation timer has expired, a game over process is immediately performed (step S36). If the continuation timer has not timed out, it is determined whether or not there has been a continuation instruction from the player such as coin insertion (step S37). If a continuation instruction has been given, a game continuation process is performed (step S38).

If it is determined in step S32 that the operation button has been pressed, it is determined whether the operation button has been repeatedly hit (step S39). If the operation button is repeatedly hit, 3 seconds are subtracted from the continuation timer (step S40), a continuation possible display screen as shown in FIG. 15C is obtained, and the process proceeds to step S35.

When the operation buttons are not repeatedly hit,
It is determined whether or not the operation button has been pressed for a predetermined time (step S41). If the operation button has not been pressed for a certain period of time, the process returns to step S32.

If the operation button has been pressed for a certain period of time, a predetermined number of seconds, for example, 10 seconds, is added to the continuation timer (step S42), and the continuation possible screen shown in FIG.

Subsequently, it is determined whether one second has elapsed (step S43). If one second has elapsed, one second is subtracted from the continuation timer (step S44). 1
If not, the process returns to step S42.

Next, it is determined whether or not the continuation timer has expired (step S45). If the continuation timer has expired, a game over process is immediately performed (step S46). If the continuation timer has not timed out, it is determined whether or not there has been a continuation instruction such as coin insertion from the player (step S47). If a continuation instruction has been given, a game continuation process is performed (step S48).

After adding 10 seconds to the continuation timer in step S42, the process may return to step S32. However, in the present embodiment, the processing after step S43 is performed without returning to step S32 after step S42. When the processing returns to step S32, the display of the continuable screen is allowed to be extended without limitation by the operation of the player. As a result, a specific player unduly occupies the game machine, which is not desirable. Therefore, in the present embodiment, there is a limitation that only one operation can be postponed for 10 seconds.

In the above embodiment, the continuous display time is shortened by repeatedly pressing the operation button, and the continuous display time is increased by continuously pressing the operation button.
Other operation modes may be used. In short, the continuous display time may be lengthened or shortened by operating the operation buttons in different operation modes.

As described above, according to the present embodiment, the duration of the display that can be continued after the game is over can be freely controlled for a short time or a long time by the operation of the player. But
Even if you want to continue the game but wait for your opponent to prepare, you can respond flexibly.

The present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the present invention is applied to a game machine installed in a game center or the like, but may be applied to a home game machine. Further, the program for realizing the game according to the above embodiment is provided by the ROM, but may be provided by another information storage medium. As an information storage medium, in addition to a memory card or the like supplied from the outside, a memory inside the game device or an HDD
Or other information storage media. Further, not only a rewritable information storage medium but also a non-rewritable information storage medium such as a CD-ROM may be used. Further, another information medium may be used.
The information medium referred to here is a medium on which information is recorded by some physical means, and allows an information processing apparatus such as a game apparatus to execute a predetermined function, for example, a game program. Things.

Examples of the information medium include a CD-R, a game cartridge, a floppy disk, a magnetic tape, a magneto-optical disk, a CD-ROM, a DVD-ROM, and a DVD-ROM.
It includes a RAM, a ROM cartridge, a RAM memory cartridge with a battery backup, a flash memory cartridge, a nonvolatile RAM cartridge, and the like. Also, communication media such as a wired communication medium such as a telephone line and a wireless communication medium such as a microwave line are included. The Internet is also included in the communication medium mentioned here.

In the above embodiment, the present invention is applied to a game device. However, the present invention can be applied to control of a game or the like in another electronic device such as a personal computer.
