Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing device, and more particularly to a game device.

[0002]

2. Description of the Related Art In recent years, many types of image processing devices called 3D game devices have been proposed. This image processing device defines various characters in a virtual space formed by a computer, and implements image processing such as capturing operation information from a player via a peripheral device such as a joystick and moving the character. . As a result of this image processing, an image viewed from a viewpoint from a three-dimensional virtual space called a virtual camera is displayed to the player via the television monitor.

As an example of such an image processing device, there is a game device that competes for superiority or inferiority of a character displayed on the screen (for example, "House of the Dead" manufactured by Sega Enterprises). In this game device, the player shoots an enemy (zombie) and moves forward while the virtual camera moves along a predetermined course in the three-dimensional space. This enemy has several weak points, and if you hit the weak points, the damage points will be added, and if the specified value is exceeded, the shot enemy will fall. Further, the time when the player should defeat the enemy is set in advance, and if the player cannot defeat the enemy within a predetermined time limit, the player is attacked by the enemy and the damage points of the player are increased. It was

Further, in this game device, when the player turns on the trigger of the gun directed to the screen, the timing until the gun detects a scanning line on the screen is calculated, whereby the coordinates on the screen where the muzzle is facing are calculated. Is calculated to determine whether or not the character has landed.

[0005]

However, this kind of image processing apparatus has the following problems.

First, in the conventional game device, the time when the player should defeat the enemy is set in advance, and if the player cannot defeat the enemy within a predetermined time limit, the player is attacked by the enemy. The player is disadvantaged because the damage points of the player increase. However, if the player defeats the enemy within the time limit, no particular consideration is given to the player's advantage. For example, even if the player defeats the enemy within a predetermined time or defeats the enemy within a predetermined time, there is no influence on the game development or the result. Therefore,
There has been a problem that a player who is skilled in shooting technology and can defeat an enemy within a limited time has less motivation to capture a game.

Secondly, in the conventional game device, in the conventional game device, there is little consideration for realistically determining whether or not the enemy has been hit. Therefore, the player cannot have a strategy of shooting an enemy while grasping the type and nature of the weapon, and it cannot be said that the game characteristics unique to the gun shooting game are sufficiently provided.

In this embodiment, the case where the game device according to the present invention is applied to a so-called arcade game type gun shooting game will be described. However, the present invention is not limited to this, and can be applied to game software for home-use game machines.

[Block Diagram of Game Device] FIG. 1 is a block diagram showing an embodiment of a game device of an arcade game type gun shooting game according to the present invention. This game device has, as basic elements, a game device body 10, an input device 11, a TV monitor 13, and a speaker 1.
It is equipped with 4.

The input device 11 is a shooting weapon such as a gun, a shotgun or a machine gun for shooting an enemy appearing in the game. In this embodiment, a shotgun is used as a weapon used by the player. The shotgun includes a light-receiving element that reads a scanning spot (light spot of an electron beam) at a landing point on a TV monitor, and a trigger switch that operates in response to a trigger operation of the shotgun. The signals of the detection timing of the scanning spot and the trigger timing are sent to an interface 106 described later via a connection cord. The TV monitor 13 displays an image of the game development situation, and a projector may be used instead of this TV monitor.

It may also include communication media (Internet, various personal computer communication networks).

The CPU 101 has a ROM 102 for storing a predetermined program and the like via a bus line, a RAM 103 for storing data, a sound device 104, an input / output interface 106, a scroll data operation device 107,
It is connected to the co-processor 108 and the geometallizer 110. The RAM 103 functions as a buffer, and writes various commands to the geometallizer 110 (display of objects, etc.), matrix writing at the time of conversion matrix calculation, and the like.

The input / output interface 106 is connected to the input device 11 (shotgun). From the detection signal of the scanning spot from the shotgun 11, the trigger signal indicating that the trigger of the shotgun has been triggered, the current coordinates (X, Y) position of the scanning electron beam on the TV monitor, and the position of the target, Whether or not, the place of impact,
The number of shots and the like are determined, and various flags corresponding to the RAM 103

The sound device 104 is connected to the speaker 14 via the power amplifier 105, and the sound device 1
After the power amplification of the acoustic signal generated in 04, the speaker 1
Given to 4.

The CPU 101 is the ROM 10 in this embodiment.
2 based on a program built in 2, game terrain development, terrain data from the ROM 109, or shape data from the shape data ROM 111 (“objects such as enemy characters” and “landscapes, buildings, indoors, underpasses, etc.”) 3D data) such as "game background" and the like, and performs situation setting of a 3D virtual space, shooting processing for a trigger signal from the input device 11, and the like.

Various objects in the virtual game space are
After the coordinate values in the three-dimensional space are determined, the transformation matrix for transforming the coordinate values into the visual field coordinate system and the shape data (building, terrain, indoors, laboratory, furniture, etc.) are stored in the geometallizer 110. It is specified. The terrain data ROM 109 is connected to the co-processor 108, and therefore terrain data such as a predetermined moving course of the camera is passed to the co-processor 108 (and the CPU 101). In addition,
The processor 108 performs a hit determination of shooting, a deviation between a camera line of sight and an object, a control calculation of a line of sight movement, and the like, and at the time of this determination and calculation, mainly performs a floating point calculation. ing.
As a result, the co-processor 108 executes the hit determination of the object and the calculation of the moving position of the line of sight with respect to the arrangement of the object, and the result is calculated by the CPU 10.
It is designed to be given to 1.

The geometallizer 110 is a shape data ROM.
111 and the drawing device 112. Shape data
In the data ROM 111, polygon shape data (buildings consisting of vertices, walls, corridors, rooms, terrain, background, hero,
3D data for allies and multiple types of enemies (eg zombies)
Data is stored, and this shape data is passed to the geometallizer 110. Geometallizer 110 is CPU1
The shape data specified by the conversion matrix sent from 01 is perspective-transformed to obtain the data converted from the coordinate system in the three-dimensional virtual space to the visual field coordinate system.

The drawing device 112 pastes a texture on the transformed shape data of the visual field coordinate system to create the frame buffer 1.
Output to 15. In order to paste this texture, the drawing device 112 is connected to the texture data ROM 113 and the texture map RAM 114 as well as to the frame buffer 115. In addition,
The polygon data refers to a data group of relative or absolute coordinates of each vertex of a polygon (polygon: mainly a triangle or a quadrangle) composed of a set of a plurality of vertices. The terrain data ROM 109 stores polygon data set relatively coarsely, which is sufficient for the camera to move in the virtual space according to the game story. On the other hand, the shape data ROM 111 stores polygon data that are more precisely set with respect to the shapes forming the screen such as the enemy and the background.

The scroll data calculation unit 107 calculates the data of the scroll screen such as characters, and the calculation unit 107 and the frame buffer 115 pass through the image synthesizing unit 116 and the D / A converter 117. To reach the TV monitor 13. As a result, the polygon screen (simulation result) such as the object (enemy) and the terrain (background) temporarily stored in the frame buffer 115 and other character information (for example, the life count value on the player side, the damage point, etc.) The scroll screen and the scroll screen are combined according to the specified priority, and the final frame image data is displayed.
Is generated. This image data is the D / A converter 117.
Is converted into an analog signal and sent to the TV monitor 13.
Images of the shooting game are displayed in real time.

[Overall Game Flow] Next, the overall game flow will be described with reference to FIG. This figure is a flowchart for explaining the outline of the game, and is roughly divided into a moving mode and a game mode. In the moving mode (S10), the virtual camera moves in the virtual game space formed in the computer system according to a pre-programmed game story, and various situations are displayed on the screen.

When the virtual camera moves to the pre-programmed enemy appearance point, the enemy is displayed on the screen (S2
0), shift to a game mode for developing a shooting game (S30). In the game mode, the player
You can move forward by moving while shooting the enemy. When the player kills the enemy, the camera moves again according to the pre-programmed game story and can move to another situation (S40; Ye.
s), it is possible to further develop the game (S1)
0-S30).

When the enemy cannot be destroyed and the hero loses the enemy or clears the last game (S4
0; No), the end of the game is determined. For example, when the damage of the main character is small (S50; No), it is possible to return to the game mode of another situation (S10 to S30) or the lost game mode. If the game parameters such as the time-up of the time set in the so-called game section and the damage value satisfy the game end condition, the game ends (S50; Y).
es).

[Game Mode] Next, the flow of processing in the game mode will be described with reference to FIG. FIG. 3 is a flowchart illustrating the processing in the game mode (S30). When the virtual camera moves in the virtual space and an enemy appears, the enemy appearance means performs a process of causing the type and number of enemies preprogrammed in the scene to appear (S3).
02). It should be noted that for the process of causing the enemy to appear, for example, a known technique such as Japanese Patent Laid-Open No. 10-165547 can be used.

With the appearance of the enemy, the virtual camera control means
The moving speed of the virtual camera is changed according to the distance between the virtual camera (viewpoint) and the enemy (S304). The process of controlling the moving speed of the virtual camera will be described later with reference to FIGS. Further, the gazing point of the virtual camera is also changed according to the distance between the virtual camera (viewpoint) and the enemy (S304). This processing will be described later with reference to FIG.

Further, the player can shoot (shoot) the appearing enemy. When the enemy is shot, the shooting result determination means determines the shooting result (S306). First, it is judged whether or not the shooting hits the enemy (hit judgment)
However, the hit flag is set to the enemy hit by the shooting, and then the damage value and the damage progress value by the shooting are calculated. The hit determination and the calculation of the damage value are performed by making use of the characteristics of the shotgun, and the details of these processes will be described later with reference to FIGS.

When the enemy disappears by shooting, the enemy moving means performs the moving process of the enemy so as to advance the enemy behind to the vacant position or the disappeared position (S308). In addition,
Regarding the movement processing of the enemy, the above-mentioned JP-A-10-1655 is used.
Known techniques such as Japanese Patent No. 47 can be used.

Thereafter, it is determined whether the game is continued. If the battle is not over yet due to the enemy remaining (S310; Yes), it is determined whether or not the enemy appears based on the program of the game story (S).
312). If an enemy should appear (S312; Ye
s), an enemy appears (S302). When the enemy is not made to appear (S312; No), the process proceeds to the determination of the shooting result for the remaining enemies (S306), and step 3
08 to step 310 are repeated. When the end of the game is determined (S310; No), the process returns to step 40.
Then, it is determined whether to return to the movement mode for moving to the next game scene (S40) or whether the game is over (S50).

[Movement of Virtual Camera] Here, an improvement relating to the movement of the virtual camera by the virtual camera control means will be described. The virtual camera is a viewpoint in the three-dimensional virtual space, and an image viewed from this viewpoint is displayed to the player via the monitor. In traditional games, when the virtual camera moves to a pre-programmed enemy appearance point,
The virtual camera has stopped moving. Therefore, the player
When an enemy appeared (when they came to a certain place), they stopped there and were shooting the enemy. The moving speed of the virtual camera was constant.

On the other hand, in this embodiment, since the moving speed of the camera is changed according to the distance between the camera and the enemy, the speed with which the player defeats the enemy affects the progress of the game. For example, the moving speed of the camera is changed so that the moving speed of the camera decreases as the distance between the camera and the enemy becomes shorter. As a result, the faster the player defeats the approaching enemy (the farther away from the player), the faster the game progresses, and as a result, a high score can be obtained. On the other hand, the slower the player defeats the enemy, the slower the game progresses, and thus the higher score cannot be obtained. That is, even when the enemy is defeated within the time limit, the speed of defeating the enemy makes a difference in the game development and the result. Also,
Since the player grasps and shoots the enemy coming toward the destination while moving to the destination, the player can enjoy the game while being tense.

Next, the relationship between the movement of the virtual camera and the enemy will be described with reference to FIG. As shown in the figure, the virtual camera advances on a predetermined orbit at a predetermined speed and angle. The virtual camera has a distance at which the player senses the enemy and a distance for changing the moving speed of the player according to the distance to the enemy (enemy sensing distance). For example, when an enemy comes within this enemy detection distance, the moving speed of the virtual camera becomes slow. The moving speed of the virtual camera gradually decreases as the enemy approaches the virtual camera,
The movement of the virtual camera stops when the enemy approaches a certain distance. As shown in the same figure, the enemy detection distance is a camera normal speed movement area in which the virtual camera moves at a normal speed, a camera low speed movement area in which the virtual camera moves at a low speed, with the position of the virtual camera as the center. The virtual camera is divided into three areas, namely, a camera movement stop area where movement of the virtual camera stops. Each division is
It is classified by the distance from the position of the virtual camera.

When the enemy is in the camera normal speed movement zone,
The player is still far away from the enemy, and the moving speed of the virtual camera does not change and the normal speed is maintained. When the enemy enters the camera low-speed moving area, the distance at which the player feels that he has to defeat the enemy, and the moving speed of the virtual camera becomes slower than the normal speed. Furthermore, when the enemy enters the camera movement stop zone, the danger that the player will be defeated by the enemy increases, and the movement of the virtual camera stops. Note that the categories that determine the moving speed of the virtual camera are not limited to the above three categories. These categories can be appropriately set according to the difficulty level of the game and the like.

Next, the flow of processing for changing the moving speed of the virtual camera according to the distance to the enemy will be described with reference to FIGS. 5 and 6A and 6B. FIG. 5 is a flowchart for explaining the process of controlling the virtual camera (S304 in FIG. 3). FIG. 6A is a diagram showing the relationship between the enemy detection distance and the position d of the enemy closest to the virtual camera. FIG. 6B is a diagram for explaining an equation for obtaining the acceleration.

First, the position d of the enemy closest to the virtual camera is obtained (S304a). As shown in FIG. 6A, the camera movement stop section is within a range of 2.5 m to the virtual camera position, and the camera low-speed movement section is 10 m from the virtual camera position.
Within the range (excluding the camera movement stop section), the camera normal speed movement section is set in a range 10 m or more away from the position of the virtual camera. Next, it is determined whether or not the position d is within the camera movement stop area (304b), and when it is determined that the position d is within the camera movement stop area (S304).
b; YES), the acceleration in the camera movement stop area is calculated (S304c). The acceleration can be calculated by the formula shown in FIG.

Next, when it is determined that the position d is not within the camera movement stop area (S304b; NO), it is determined whether or not it is within the camera low speed movement area (304d), and the camera low speed movement is performed. If it is determined to be within the ward (S304
d; YES), and calculate the acceleration of the camera low-speed moving area (S304c). On the other hand, when it is determined that the camera is not in the low-speed camera movement zone (S304d; NO), the acceleration of the camera movement stop zone is calculated (S304f).

Based on the acceleration calculated above, the moving speed s of the virtual camera is calculated (S304g), and it is determined whether the calculated moving speed s is less than 0 (S304).
h). When the calculated moving speed s is less than 0 (S304h; YES), 0 is set to the moving speed s (S304i). On the other hand, when the calculated moving speed s is not less than 0 (S304k; NO), it is determined whether the calculated moving speed s is larger than 1, and when it is larger than 1 (S304k; YES). ), 1 is set to the moving speed s.

In other words, the position d of the virtual camera (the distance between the virtual camera and the character) is first calculated. Next, the area including the position d is determined, and the acceleration of the virtual camera is calculated based on the area including the position d.
Then, the moving speed of the virtual camera is calculated based on the acceleration.

When a plurality of characters are defined (appearing) in the virtual space, the moving speed of the virtual camera may be returned to normal when all the characters are destroyed. Specifically, it is determined whether or not the characters appearing in the virtual space have been wiped out. When it is determined that the virtual camera is completely wiped out, the moving speed of the virtual camera is set to the normal speed.

Further, the advancing direction of the virtual camera and the story progression of the game change (or enter another branch prepared in advance) according to the time from the appearance of the enemy character in the virtual space until the enemy character is completely destroyed. You may do it. Specifically, the time from when the enemy character appears in the virtual space until it is completely destroyed is measured. Depending on the measured time, the moving direction of the virtual camera or the story progress of the game is selected.

According to the above, the moving speed of the virtual camera is
It changes according to the distance between the virtual camera and the enemy, and the moving speed becomes slower as the distance to the enemy gets closer. Therefore,
If the player defeats the enemy while the distance to the enemy is long, the moving speed of the virtual camera does not slow down. That is, the faster the player defeats the enemy, the faster the game progresses, and as a result, the higher score can be obtained.

Further, by changing the moving speed of the virtual camera according to the distance to the enemy, it becomes possible to produce a tense atmosphere. For example, when the target enemy comes from the back of the screen, the player (virtual camera)
Moving to a destination. When the enemy is far from the player, the player's movement speed does not change in particular, so that the player feels as if he or she prefers to proceed to the destination. However, as time passes and the enemy approaches the player, the player's movement speed decreases,
The player recognizes that he is in a fighting position with the enemy and feels nervous. Finally, when the enemy comes within a certain distance, the player stops moving and keeps that position until the end of the battle with the enemy. The player defeats the enemy with the sense of urgency that he might be defeated. In this way, the movement of the player and the movement of the enemy are intertwined with each other, so that a more tense atmosphere can be produced.

[Focusing Point of Virtual Camera] By the way, the virtual camera moves in the three-dimensional virtual space according to the program,
As shown in FIG. 7, the line of sight of the camera is set so as to face a certain point (gazing point) in space, and an image is formed so that the gazing point is at the center of the display screen. The gazing point is controlled according to the situation of the enemy in the line-of-sight direction of the virtual camera. In this control, the speed at which the gazing point follows the enemy is changed based on the distance between the virtual camera and the enemy. More specifically,
The gazing point is controlled so that when an enemy enters the enemy-sensing distance, the enemy follows the enemy, and as the distance from the enemy decreases, the speed of following the enemy increases.

An example of controlling the gazing point based on the distance between the virtual camera and the enemy will be described with reference to FIG. The gazing point of the virtual camera is preset according to the program. Therefore, when an enemy enters the enemy detection distance (enemy 1 in the figure), the virtual camera's gazing point will follow the enemy,
Since the enemy is still far away, the gazing point slows down the speed at which the enemy follows. Further, when the enemy approaches the virtual camera (enemy 2 in the figure), the speed at which the gazing point follows the enemy is set to be high. And
When the enemy approaches a certain distance (enemy 3 in the figure), the speed at which the gazing point follows the enemy becomes maximum.

In other words, first, the gazing point setting means sets the gazing point of the virtual camera. Next, an enemy for which the gazing point of the virtual camera should be set is selected. The enemy selects an enemy that is within the enemy detection distance and is closest to the virtual camera. Then, the speed at which the gazing point is moved is determined according to the position of the enemy, and the gazing point is moved at the determined speed.

[Shotgun Shooting Result Judgment Processing] Next, an improvement in shooting result judgment processing when a player shoots an enemy will be described. In this embodiment,
The weapon possessed by the player is set to a shotgun. Therefore, it is desirable to determine the result of the shooting so that the effect of the shooting that takes advantage of the characteristic of the shotgun that “the bullet spreads over a wide area” is obtained. The characteristics of this shotgun are, for example, that if it is fired at a nearby object, the bullet will land with a high density in a narrow area, and it will exert sufficient power, while if it is fired at a distant object, the bullet will spread and spread over a wide range. Although it hits, it can be understood that the density is low and sufficient killing ability cannot be obtained.

Therefore, in this embodiment, from the viewpoint of changing the damage given to the enemy according to the distance to the enemy, and from the viewpoint of changing the effective range of the bullet (power of the bullet) according to the distance to the enemy, The damage done to the enemy by the shooting is decided based on the viewpoint that the damage done to the enemy is also changed depending on the landing point within the effective range.

FIG. 8 is a diagram showing an example of the relationship between the distance of an enemy and the power of a bullet. As shown in the figure, the power of the bullet and the effective range of the bullet are set so as to change according to the distance to the enemy. For example, the power of a bullet is 100 pt when the distance to the enemy is 3 m, while it is 6 at 5 m.
It is reduced to 30pt at 0pt and 7m. On the other hand, the effective range of the bullet is 20 cm when the distance from the enemy is 3 m, whereas it is expanded to 60 cm at 5 m and 70 cm at 7 m. FIG. 9 is a diagram showing an example of the relationship between the effective range of bullets and the power of bullets. As shown in the figure,
The power of the bullet is set so that the point of impact of the bullet decreases as the distance from the point targeted by the player (the center of the concentric circle) increases, and the damage to the enemy is reduced. An example of the relationship between the distance to the enemy and the effective range of the bullet is shown in FIG.

The shooting result of the player based on such setting will be described with reference to FIGS. 8 and 9. The player shoots an enemy (for example, head) when the enemy approaches within 3 m. For example, 100pt of damage can be given. On the other hand, when the enemy is 5 m, even if the same head is shot, only 60 pt of damage can be done. However, the effective range of the bullet is 20 cm at 3 m, but it has expanded to 50 cm at 5 m, so the possibility of hitting the head increases, and at the same time as other parts of the head, It also hits the chest and shoulders and is likely to cause damage. However, when aiming at the center of the head, the impact on the chest is outside the range of 100% of the power of the bullet, 80%
On the other hand, aiming at the neck can damage the head and chest with 100% attack power. In this way, depending on the distance to the enemy,
Since the effective points to aim at will also change, it is expected that you will be able to capture the characteristics of the shotgun before shooting, which can increase the fun of the game.

Next, the flow of processing when the player shoots an enemy will be described. FIG. 11 is a flowchart illustrating the processing in the shooting result determination processing (S306 in FIG. 3). First, when a player shoots an enemy, the hit determination means performs hit determination processing to determine whether or not the bullet has hit the enemy (S306a). The hit determination process will be described later in detail with reference to FIGS. A hit flag is set for the enemy determined to have hit the bullet in the hit determination processing.

Next, with respect to the enemy for which the hit flag is set, the calculating means for calculating the damage performs the damage processing for calculating the damage due to the shooting (S306b).
The damage processing will be described later in detail with reference to FIGS. Further, the calculation means for calculating the degree of damage performs damage processing for determining the damage degree of the enemy according to the result of damage shooting and visually expressing it (S306c). The damage process will be described later in detail with reference to FIG.

[Hit Determination Process] Next, the flow of the hit determination process when the player shoots an enemy will be described with reference to FIG. FIG. 12A is a flowchart illustrating the flow of the hit determination process. When the player shoots (S306a1; YES), the coordinates of the enemy are converted into a coordinate system having the player's position as the origin and the shooting direction vector as the Z axis (S306a2).

Then, the radius DR, which is the effective range (spread spread) of the bullet at the enemy's Z position, is obtained (S3
06a3), the distance L, which is the distance from the enemy's Z axis, is obtained (S306a4). And the radius R of the enemy's ball collision
Is calculated (S306a5), and based on the radius DR, the distance L, and the radius R, it is determined whether or not the enemy has landed (S30).
6a6). Specifically, the radius R and the radius DR are greater than the distance L.
Or the total value of the radius R and the radius DR is equal to the distance L, it is determined that the bullet has hit the enemy (S306a6; YES). On the other hand, when the total value of the radius R and the radius DR is smaller than the distance L (S306a6; NO), it is determined that the bullet has not hit the enemy (S306a7).

When hitting an enemy, the cross section of the conical collision of the shotgun at the Z position of the enemy is divided into a predetermined number (for example, 16) to determine which part the enemy occupies (S306a8). ). FIG. 12B shows
It is a figure which shows a mode that the cross section of a conical collision is divided | segmented into the parts 1-16.

When the processes of S306a1 to S306a8 are performed for all the appearing enemies (S306a9), the enemies are rearranged according to the Z position (S306a10), Z
The portion hitting the conical collision from the front of the shaft is filled (S306a11). It is determined whether or not the enemy has filled at least one of the portions 1 to 16 (whether or not the empty portion has been filled) (S306a12). If not, a hit flag is set for the enemy. Not set (S306a13). On the other hand, if it is filled,
A hit flag is set for the enemy (S306a1).
4). That is, when the hit portion is already filled with other enemies, it is determined that the bullet is out and the hit flag is not set.

The processes of S306a1 to S306a14 are repeated until the hit determination process is completed for all the enemies.

According to this, it becomes possible to perform the hit determination in the case of the shotgun without performing the hit determination of the vector and the ball collision a plurality of times.

[Damage Processing] Next, the flow of damage processing for calculating the damage given to the enemy in response to the shooting by the player will be described with reference to FIG. FIG.
3 is a flowchart illustrating a flow of damage processing. It should be noted that the enemy's body has a predetermined part (for example, a head
(Arms, legs, chest, etc.) are set, and for each part,
Predetermined parts (for example, “shoulder / upper arm / lower arm / hand” for “arm”) are set in advance. The hit flag set in the hit determination process described in FIG. 12A can be used to determine whether or not the bullet hits each part of the enemy's body.

First, it is determined whether or not the hit flag is set for a predetermined part (S306b1), and if the hit flag is set, the part closest to the impact point is selected (S306b2). Next, the effective range of the shotgun at the hit point is specified (S306b).
3) Calculate the distance from the central trajectory for the selected part (S306b4). Then, the damage rate is calculated based on the distance from the central trajectory (S306b).
5).

This damage rate can be calculated by a calculation formula as shown in FIG. 13 (B). In the formula, the minimum damage rate (MAX_DAMAGE_RATE)
Is the percentage of the power of the bullet at the position farthest from the landing within the range of the shot, for example, 0.1 is set. In addition, the range of maximum damage to the maximum hit radius (MAX_DAMAGE_RADIUS_RATE) is the percentage that determines the range where the same power should be maintained from the center of the shot range. As a result, a certain range from the landing point is formed to maintain the same power. Damage range (SHOT
_GUN_RADIUS) is the range where the power of the shotgun at the hit point is effective, and the range of shots. The distance from the central trajectory (HIT_LEN) is the distance between the central trajectory and the enemy and is the number obtained by subtracting the radius of the ball collision of the enemy.

When the damage rate is calculated in S306b5, the damage table shown in FIG. 14 is referred to, and the damage value determined by the distance to the enemy and the part part is specified (S306b6). FIG. 14 is a diagram showing an example of the structure of the damage table. The damage table stores the damage value for determining the damage value of the landed enemy. In the figure, it is assumed that the average physical strength value of the enemy is set to 200 points. As shown in the figure, the damage value is set in correspondence with the distance between the player and the enemy and the hit portion. The physical strength value of the enemy is calculated by adding a subtraction process of the damage depending on the distance from the impact point to the damage value.

For example, when the distance to the enemy is 3 m or less and the part is the arm, the damage value given to the enemy is "30" points. The damage value given to the part is calculated by multiplying the damage rate by the damage value (S306b7).

When the damage values have not been calculated for all parts, the damage values are calculated for other parts in the same manner (S306b8; NO). On the other hand, when the calculation of the damage value is completed for all the parts, the total damage value of the parts is calculated by summing the damage values of the parts. That is, the sum of the damage values of the respective parts becomes the damage given to the enemy and is subtracted from the physical strength value of the enemy. When the physical strength value after the subtraction is equal to or less than the predetermined value, the enemy disappears from the screen.

FIG. 15 is a diagram showing an example of a hit image of an object (enemy). In the figure, short distance and long distance,
The effective range of the bullet when it hits the same place is a dotted circle, and the damage is indicated by ☆. When hitting at a short distance as shown in FIG. 15 (A), the abdomen is hit, and there are few hit parts, but each part is greatly damaged. Further, as shown in FIG. 15 (B), when hitting at a long distance, although it is hit in a wide range over the whole body, it can be seen that each part receives little damage. According to the above, the moving speed of the virtual camera changes based on the distance between the virtual camera and the character, while the amount of damage caused by the shooting to the character changes based on the distance between the virtual camera and the character. Therefore, "If you attract and shoot the enemy, you can hit the enemy with high power,
"Enemy One" can be defeated quickly, but the movement speed itself becomes slow. Therefore, if the number of enemies is large, even if the power of shooting is small, it is possible to attack a wider range by intentionally shooting from a distance, so in the end, it may wipe out the enemies faster and proceed faster. You can make players feel the conflict such as, and increase the fun of the game.

[Damage Processing] Next, the flow of damage processing for displaying the damage state of the enemy in response to the shooting by the player will be described. The damage processing visually expresses how much damage the enemy has received in response to the shooting by the player. The damage (damaged state) is added to the damage progress value given to the enemy each time the enemy hits, and is displayed according to the added result. The damage progress value given to the enemy by landing is set by the distance to the enemy. Specifically, the closer the distance to the enemy is, the larger the damage progress value is. The farther the enemy is from, the smaller the damage progress value is. Is set.

Here, the enemy has damage parts for expressing damage (damaged state) according to a predetermined stage,
It is prepared for each part. For example, with regard to the chest part of the body of the enemy A, there are five stages of damage parts (0 →
1 → 2 → 3 → 4). These damaged parts are set so that the degree of damage increases as the stages progress. For example, stage 0 is undamaged, stage 1 is part of the chest with blood, stage 2
Indicates a state where a part of the chest is killed, stage 3 indicates a state where the entire chest is killed, and stage 4 indicates a state where the chest is separated. The damage stage and expression can be set differently depending on the type of enemy.

FIG. 16 is a flow chart for explaining the flow of the damage processing. The hit flag set by the hit determination process described with reference to FIG. 12 can be used to determine whether or not the bullet hits each part of the enemy's body.

First, it is determined whether or not the hit flag is set for a predetermined part (S306c1), and if the hit flag is set (S306c1: YE).
S), for the part, select the part closest to the impact point (S306c2). Then, referring to the damage progress value table shown in FIG. 17, the damage progress value is specified based on the distance to the enemy (S306c3).

FIG. 17 is a diagram showing an example of the structure of the damage progress value table in which the damage progress value is set according to the distance to the enemy. As shown in the figure, the damage progress value of a part A of a certain part is set such that the damage progress value is larger as the distance to the enemy is shorter and the damage progress value is smaller as the distance to the enemy is farther. . In the figure, only the damage progress value of the part A (for example, the upper arm of the arm) is displayed. Descriptions of other parts (for example, lower arm of arm) and other parts (for example, head) are omitted.
Similarly, the damage progress value is set.

Next, when the damage progress value is specified, it is added to the damage progress value of the part stored in the predetermined storage area (S306c4). That is, when the part has already been impacted, the damage progress value due to the current impact is added to the damage progress value due to the impact, and the total value of the damage progress values is increased. The parameter of the display damage part is referred to based on the damage progress value after the addition, and the display damage part to be displayed as a result of the shooting is specified (S306c).
5).

More specifically, the display damage part is specified by the expression "display damage part = part damage progress value / 10 (round down)." For example, when the distance from the enemy at the time of impact is 8 m, the damage progress value of the part is "7" and "7/10 = 0 (round down)", so the damaged part is "0". Stages are displayed. Further, when the landing is performed at the same distance, the damage progress value is “7 + 7 = 14”, which is “14/10 = 1 (rounding down fractions)”, so that the damage parts are displayed in the “1” stage. .

On the other hand, when the distance from the enemy at the time of impact is 3 m, the damage progress value of the part is "15",
Since it is "15/10 = 1" (fractions are rounded down), the damage parts at the "1" stage are displayed. further,
When landing at the same distance, the damage progress value is “15 + 1
5 = 30 ", and" 30/10 = 3 (round down) "
Therefore, the damage parts are displayed in the "3" stage. As described above, when the distance at the time of landing is short, the state of damage becomes strong with a small number of times of landing.

[Second Damage Processing] Next, the second damage processing performed by the shooting on the enemy (character) will be described. Here, of the entire effective range of the shooting (damage range), the ratio occupied by the range where the damage range and the collision range of the enemy contact (hit judgment part) (hereinafter,
It is called the "first contact ratio". ) Is calculated, and the damage value is calculated according to the calculated ratio. Specifically, the damage value is calculated by multiplying the damage value of the damage range by the first contact ratio. Below, FIG.
Will be specifically described.

FIG. 18 is a diagram for explaining the second damage processing. In FIG. 6A, the damage range includes 100% of the hit determination portion. The enemy's damage is calculated by the formula “enemy's damage value = damage value × first contact ratio (%)”. Therefore, when the damage value is set to 100, the enemy's damage value is "damage value (100) x first contact ratio (100
%) = 100 ”, so 100 is obtained.

In FIG. 9B, the damage range includes 50% of the hit determination portion. If the damage value is set to 100, the enemy's damage value is "damage value (1
00) × first contact ratio (50%) = 50 ”, and therefore 50. Note that the fact that the damage range includes 50% of the hit determination portion also means that the enemy collision range and 50% of the damage range overlap.

Next, another example of the second damage processing will be described. In another example, the ratio of the area (hit determination part) in which the damage range and the enemy collision range contact each other to the entire enemy collision range (hereinafter referred to as “second
Contact rate ”. ) Is calculated, and the damage is calculated based on the calculated second contact ratio. Specifically, the damage value is calculated by multiplying the damage value of the damage range by the second contact ratio. Below, FIG.
A specific description will be given using (C) and (D).

In FIG. 9C, 100% of the hit determination portion is included in the entire enemy collision range. The damage value of the enemy is calculated by the formula “damage of the enemy = damage value × second contact ratio (%)”. Therefore, when the damage value given to the entire damage range is set to 100, the enemy's damage value is "damage value (10
0) × contact ratio (100%) = 100 ”, so 1
It becomes 00.

On the other hand, in FIG. 6D, 50% of the hit determination portion is included in the entire enemy collision range. Therefore, the damage value given to the entire damage range is 1
If set to 00, "damage value (100) x
Depending on the contact ratio (50%), the enemy's damage value is 50
Becomes In addition, the fact that 50% of the hit determination portion is included in the entire collision range of the enemy means that the collision range of the enemy and 50% of the damage range overlap with each other.

Next, a method of calculating the area (hit determination portion) where the damage range and the enemy collision range contact each other will be described with reference to FIG. First, as shown in (E) of the same figure, the damage range is subdivided into a grid pattern of predetermined intervals. Then, the number of grids overlapping the collision range is calculated. Finally, in the case of the first contact ratio, the ratio of the lattices in the overlapping portion to the number of lattices in the entire damage range is calculated. The second contact rate is
Calculate the ratio of overlapping grids to the number of grids in the entire collision area.

As another example, the damage range and the collision range are projected on a virtual image for judgment (not displayed), and the number of pixels in the overlapped virtual image is counted. Good.

The area of the overlapping portion and the damage value do not have to correspond exactly, and for example, when "the overlapping portion is 1% or more and less than 10%", "damage is 10%".
% "And" overlapping portion is 10% or more and less than 30% "," damage is 30% ".

Further, the damage range is not limited to the circular shape, and an oval shape or a polygonal shape can be appropriately set. Further, by using it together with other damage processing, it is possible to execute the further divided damage processing.

Next, description will be made regarding a case where the enemy, which is the target of the shooting, is a humanoid and the impact on the enemy is calculated by the second damage processing. FIG. 19 is a diagram illustrating the second damage process when the enemy is a humanoid.

As shown in FIG. 19A, when the damage range overlaps the enemy's waist or higher, about 80% of the entire damage range overlaps the enemy's collision range (judgment of hitting the damage range). 80% of the portion is included). If the damage value given to the entire damage range is set to 100, the enemy's damage value is
"Damage value (100) x first contact ratio (80%) =
It becomes 80 by "80".

When the damage determination is performed for each part, the area occupied in the damage range is calculated for each part, and the damage value is calculated based on the total area. For example, if your arms and head are 10%, your hips are 20%, and your chest is 30%, the damage value for each is 20 for both arms, 10 for your head, 20 for your hips, and 30 for your chest. "20 + 10 + 2
0 + 30 = 80 ”gives 80.

When the damage range overlaps with one arm as shown in FIG. 11B, about 1 of the entire damage range is included.
It is determined that 0% overlaps the collision range of the enemy. When the damage value is set to 100, "damage value (100) x first contact ratio (10%) = 10"
Gives an enemy damage value of 10. If the damage determination is performed for each part, the damage value for the arm is 10.

When the damage range overlaps both feet as shown in FIG. 10C, about 4 out of the entire damage range is detected.
It is determined that 0% overlaps the collision range of the enemy. When the damage value is set to 100, "damage value (100) x first contact ratio (40%) = 40"
As a result, the enemy's damage value becomes 40. When the damage determination is performed for each part, the damage value is 40 for both feet, and the damage value is 20 for the right foot and the left foot.

When the damage range overlaps with two enemies as shown in FIG. 9D, the calculation is performed for each enemy. First, since the damage range of the enemy A overlaps with one arm, it is calculated that about 10% of the entire damage range overlaps with the collision range of the enemy. On the other hand, for the enemy B, since the damage range overlaps with the upper body, about 50% of the entire damage range is calculated to overlap with the enemy's collision range. Damage value is 100
In the case of the enemy A, the damage value of the enemy A is 10, which is “damage value (100) × first contact ratio (10%) = 10”. For the enemy B, "damage value (100) × first contact ratio (50%) = 50", the enemy damage value is 50. As a result, "enemy B is enemy A
It's located a little farther back than it, but the more damage it receives, the more damage it does. "

As described above, by finely correlating the contact area between the damage range and the collision range of the enemy with the damage value given to the enemy, it is possible to determine the damage more realistically and fairly. For example, "aim so that more enemies are included in the effective range of the bullet",
It becomes possible to provide the gamers with a game characteristic unique to a shooting game, such as "aim to hit a stronger enemy more heavily".

It is also possible to combine the second damage processing and the first damage processing. [Other Embodiments] In the above embodiments, the case where the present invention is applied to a gun shooting game has been described, but the present invention is not limited to this and can be applied to other types of games. For example, a plurality of characters are defined in the three-dimensional virtual space, the first character (eg, enemy character) operates according to a predetermined program, and the second character (player character) is operated by the player. A case of a game that operates according to information will be described.

In this case, in the control processing of the virtual camera, the position of the player character is adopted instead of the position of the virtual camera, and the moving speed of the virtual camera is changed based on the distance between the player character and the enemy character. You may control to. Further, in the process of changing the moving speed of the gazing point of the virtual camera, similarly, the speed at which the gazing point of the virtual camera follows the enemy character is controlled so as to be changed based on the distance between the player character and the enemy character. May be.

In the damage calculation process, the effective range of attack by the player character can be applied instead of the effective range of shooting. In this case, the damage given to the enemy character is the distance between the player character and the enemy character, the effective range of the attack that changes according to the distance between the player character and the enemy character, and the distance of the enemy character from the center of the effective range of the attack. , May be used to calculate the damage. It should be noted that even when the player character (teammate character) is attacked, it can be calculated by the same method.

Furthermore, in the second damage calculation process, the damage may be calculated in accordance with the ratio of the range in which the effective range of the attack and the collision range of the enemy character contact in the effective range of the attack. Good.

Further, the damage calculation process can be applied to a game in which a player damages an object placed in the virtual space. Specifically, the position information of the character that moves according to the operation of the player and the position information of the object are acquired. The distance between the character and the object is acquired based on these position information, and the size of the hit determination area is determined based on this distance. When it is determined that the hit determination area and the object are in contact with each other, the amount of damage to the object is generated based on the distance between the character and the object. Then, the object is damaged based on the generated damage amount.

[0118]

According to the present invention, the faster the enemy is defeated, the more advantageously the game can be developed. Therefore, the game result suitable for the skill of the player can be obtained. Further, according to the present invention, the result of the shooting is determined by the configuration according to the characteristics of the gun, so that the player can enjoy the game with a strategy that takes the characteristics of the gun into consideration. Further, according to the game device of the present invention, it is possible to determine a more realistic and fair damage by finely associating the result of shooting with the damage value given to the enemy.
