Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a game device and an information storage medium.
[0002]
[Background Art and Problems to be Solved by the Invention]
Recently, game devices that display underwater conditions such as fishing, lure fishing and scuba diving on the screen are gaining popularity. In such a game device, an image of an extraordinary sight of fish and other creatures swimming around in the sea will delight the player.
[0003]
In general, there are a school of fish swimming around in the sea, and in a game device that displays an image of the sea, displaying such a school of fish can provide a more realistic and high-quality image expression.
[0004]
When controlling a moving object that acts as a group like a school of fish, there is a method of expressing the movement of the group by completely controlling each moving object constituting the group. When expressing the movement of a group by this method, it is necessary to calculate the movement motion for all the moving objects belonging to the group, and the calculation amount becomes enormous. In particular, in the case of a game apparatus that generates an image of a school of fish whose movement changes in real time due to an input or other factors, an increase in calculation load also causes other processing to be pressed. Such a situation can be avoided if high-performance hardware is prepared, but the cost increases.
[0005]
Also, if the movement of the group is simplified, only unnatural, monotonous and realistic image expression can be achieved. Nowadays, the quality of the game image is also a major factor that affects the fun of the game. Unnatural, monotonous and realistic game images cause the fun of the game itself to be halved.
[0006]
The present invention has been made in view of the problems of the conventional game device as described above, and an object of the present invention is an image that realistically represents various movements of a moving object that moves in a group. It is an object of the present invention to provide a game device and an information storage medium that can generate the information in real time with a small calculation load.
[0007]
[Means for Solving the Problems]
A game apparatus according to the present invention is a game apparatus in which a plurality of moving objects moving in an object space are displayed, and a group movement content calculating means for calculating movement contents of the plurality of moving objects moving in a group And an image generating means for generating in real time an image including a plurality of moving objects that move in groups based on the moving contents, wherein the group moving contents calculating means reads one moving object in the group as a reader A reader determination means for determining the movement content of the leader mobile object, and a movement content determination means for determining the movement content of the leader mobile object, so that other mobile objects belonging to the group follow the leader based on the movement content of the leader And a moving content determining means other than the leader for determining the moving content.
[0008]
The information storage medium according to the present invention is characterized by including information necessary for realizing the above means.
[0009]
In the present invention, when a group is expressed, a leader who is a representative of the group is determined, and others follow the leader, so that the expression of the group can be effectively reproduced with a small calculation load. For example, it is possible to generate an image including a group in real time with a small calculation load by changing the movement of the reader in accordance with situations such as various external factors and temporal factors. Therefore, it is possible to provide a game apparatus and an information storage medium that can display a group movement in real time without using other processing without using high-performance hardware.
[0010]
The game device of the present invention is characterized in that the leader determining means changes the leader at a predetermined timing.
[0011]
The information storage medium according to the present invention is characterized by including information necessary for realizing the above means.
[0012]
By changing the leader at a predetermined timing as in the present invention, it is possible to express various movements of a group that does not simply follow the head. According to the present invention, it is possible to generate an image of a group that performs a variety of realistic movements with a small calculation load.
[0013]
The predetermined timing may be, for example, when a predetermined time has elapsed or when a predetermined positional condition is satisfied.
[0014]
Which mobile object the leader is to be selected may be determined randomly or according to a certain rule.
[0015]
In the game device of the present invention, the movement content determination means other than the leader determines the timing of the change in the movement direction and / or direction of the other mobile object belonging to the group as the distance between the other mobile object and the leader. It is characterized by including the means to delay based on.
[0016]
The information storage medium according to the present invention includes information necessary for realizing the above means.
[0017]
For example, when one of the movement direction and the direction of the leader changes, it is desirable to delay the timing for changing one of the movement direction and the direction of the moving object as the distance from the leader increases.
[0018]
Here, the moving direction means the traveling direction of the moving object, and the direction means the direction in which the moving object is arranged, and how much it is rotated from the reference state. To do.
[0019]
By simply following the leader, the mobile objects belonging to the group only move in parallel with the movement of the leader. However, according to the present invention, since the tracking is delayed according to the position, it is possible to generate a more natural and realistic group of motion images.
[0020]
In the game device of the present invention, the movement content determination means other than the leader keeps the movement so that the distance between the moving object belonging to the group and the other moving object closest to the moving object is a predetermined distance. It includes means for correcting at least one of the moving direction and direction of the body object.
[0021]
The information storage medium according to the present invention includes information necessary for realizing the above means.
[0022]
If the movement contents of other moving objects are determined only by the relationship with the leader, the other moving objects may come too close to each other and may stick or overlap. According to the present invention, such a situation can be prevented by correcting at least one of the moving direction and the moving direction and direction of the moving object based on the relationship with the closest other moving object.
[0023]
Moreover, since the correction is performed based on the relationship with the closest moving object, the sticking prevention process can be efficiently performed with a small calculation load.
[0024]
In the game apparatus of the present invention, the movement content determining means other than the leader includes means for correcting at least one of the other moving object speed and acceleration based on the distance between the other moving object belonging to the group and the leader. It is characterized by including.
[0025]
The information storage medium according to the present invention includes information necessary for realizing the above means.
[0026]
According to the present invention, it is possible to more naturally express an operation in which a moving object or the like that is too far from a leader approaches the leader.
[0027]
The game apparatus according to the present invention is characterized in that the leader movement content determining means determines the movement content of the leader based on at least one of the movement content and position of the target object in the object space.
[0028]
The information storage medium according to the present invention includes information for realizing the above means.
[0029]
For example, if the target object is a moving object, the movement content of the leader may be determined so as to follow it. In addition, when the target object is a stationary object, the movement content may be determined so that the leader can look around it.
[0030]
Further, the target object does not necessarily need to be an object existing in the object space, and may be, for example, a virtual camera or a coordinate point representing a simple position.
[0031]
In the game device and the information storage medium of the present invention, the moving object is a fish object.
[0032]
According to the present invention, various realistic fish school images can be generated in real time with a small calculation load.
[0033]

[0052]
The processing unit 100 includes a game calculation unit 110.
[0053]
Here, the game calculation unit 110 receives coins (price) acceptance processing, game mode setting processing, game progress processing, selection screen setting processing, and processing for determining the position and direction of a moving object (boat, fish, character, etc.). , Processing to determine the viewpoint position and line-of-sight direction, processing to reproduce the motion of the moving body, processing to place an object in the object space, hit check processing, processing to calculate game results (results), game space where multiple players are common Various game calculation processes such as a process for playing the game or a game over process are performed based on operation information from the operation unit 130, information from the memory card 180, a game program, and the like.

[0054]
The game calculation unit 110 includes a group movement content calculation unit 120 that calculates the movement contents of a plurality of moving objects that move in groups.
[0055]
The group movement content calculation unit 120 includes a leader determination unit 122 that determines one mobile object in the group as a leader, a reader movement content determination unit 124 that determines the movement content of the mobile object of the leader, A moving content determination unit 126 other than the leader that determines the moving content so that other moving objects belonging to the group follow the leader based on the moving content.
[0056]
That is, in the present embodiment, the operation of the fish school is controlled by determining one fish in the fish school as a leader, determining the movement contents of the leader, and based on the movement contents of the leader, other fish belonging to the fish school. The movement is determined so that the fish follows the leader.
[0057]
FIG. 4 is a diagram for explaining the relationship between the movement of the school of fish and the movement of the leader.
[0058]
In the present embodiment, one fish belonging to the fish school 230 is determined as the leader 240, and fish other than the leader belonging to the fish school (hereinafter referred to as other fish) are controlled to swim around the leader. Therefore, if the movement direction of the leader is 250, the school of fish 230 moves in the same direction as the leader in principle. However, the shape of the entire group and the direction of movement of individual fish seem to be irregular at first glance due to the change processing of the leader, the processing of delaying the follow-up behavior of other fish, and the processing of preventing other fish from sticking together. This is a realistic representation of the diverse movements of the school of fish that exist.
[0059]
FIG. 5 is a flowchart for explaining an outline of the control of the present embodiment.
[0060]
First, in this embodiment, the leader is determined (steps S10 and S20), and the operation of the leader is determined (step S30). Then, the operation of another fish belonging to the school of fish is determined based on the operation of the leader (steps S40 and S50). When the movement of each individual is determined for the movement of the leader, the movement of each individual is determined based on only the relationship with the leader in principle. That is, for example, each individual determines the movement contents of each individual based on movement information such as the position, speed, acceleration, movement direction (traveling direction), and direction of the leader.
[0061]
By doing in this way, the expression of a group can be effectively reproduced by following a leader with a small calculation load compared with the case where it controls individually for each individual of a group.
[0062]
The leader determining unit 122 performs processing necessary for changing the leader at a predetermined timing. As a result, various movements of the group that do not simply follow the head can be expressed. For example, when changing the direction of movement of a school of fish, simply changing the direction of movement of the leader will cause other fish to draw the same movement trajectory as the leader. However, if the direction of movement is changed by changing the leader, it is possible to represent more diverse and realistic group movements.
[0063]
FIGS. 6A to 6D are diagrams for explaining the movement of the school of fish accompanying the leader change. FIG. 6A is a diagram showing a state where the school of fish is moving in the direction of 340 with 320 as a leader. Since other fish belonging to the school of fish follow the leader, they move along the same movement trajectory as the leader moves in parallel. Here, it is assumed that the leader is changed to 330 and the direction of the leader is changed as shown in FIG. Then, as shown in FIGS. 6C and 6D, the other fish belonging to the group gradually turn toward the new leader 330, and the entire group moves in the direction of 350. As described above, according to the present embodiment, it is possible to express in real time the operation of a school of fish following a small fish that behaves suddenly with a small calculation load.
[0064]
In addition, for example, even when the leader is configured to follow a predetermined target, it is possible to express various groups of operations by changing the leader. For example, when the direction and moving direction of the leader are determined by the direction from the leader to the target, the moving direction and direction of the fish belonging to the group can be changed by changing the leader. By changing the leader in this way, diverse and realistic group movements can be realized more easily.
[0065]
Note that the timing of changing the leader may be, for example, when a predetermined time has elapsed or when a predetermined positional condition is satisfied. Which mobile body the leader is to be selected may be determined randomly or according to a certain rule.
[0066]
The leader movement content determination unit 124 also performs processing for determining the movement content of the leader based on at least one of the movement content and position of the target object in the object space.
[0067]
For example, as shown in FIG. 2, a school of fish 210 that follows the movement of the lure appears in the game image of the present embodiment. In the present embodiment, the school of fish following the movement of the lure is expressed by determining the movement of the leader based on the position and speed of the target object.
[0068]
The movement content determination unit 126 other than the leader is necessary for delaying the timing of the change of at least one of the movement direction and direction of the other mobile object belonging to the group based on the distance between the other mobile object and the leader. Also perform the processing.
[0069]
FIGS. 7A, 7B, and 7C are diagrams for explaining how fish belonging to a group follow in a delayed manner according to the distance from the leader.
[0070]
As shown in FIG. 7A, when the leader fish 410 changes the traveling direction and direction, in this embodiment, the other fish belonging to the group do not change the direction at the same time as the leader. First, the traveling direction and direction are changed so that the other fish 420 and 430 within the first distance (L1) from the leader follow the leader. Then, the timing and direction are changed so that the fish 440, 450, and 460 within the second distance (L2) from the leader follow the leader with a slight shift in timing. In this embodiment, since the fish is directed in the traveling direction, the traveling direction matches the direction.
[0071]
In this way, it is possible to express how the movement of the leader propagates from the side closer to the leader, and it is possible to express a more natural and realistic group.
[0072]
In addition, the movement content determination unit 126 other than the leader moves the moving object so that the distance between the moving object belonging to the group and the other moving object closest to the moving object maintains a predetermined distance. Also, a process for correcting at least one of the orientations is also performed.
[0073]
Further, the movement content determination unit 126 other than the leader also performs a process of correcting at least one of the other moving object speed and acceleration based on the distance between the other moving object belonging to the group and the leader.
[0074]
Next, a control example of the operation of the fish school according to the present embodiment will be described with reference to FIGS.
[0075]
In the present embodiment, the following processing is performed for each frame to control the operation of the fish school.
[0076]
The loop processing for each group in steps S110 to S360 is performed for the number of fish schools. These processes include a process related to the leader (steps S120 to S140), a process related to other than the leader (steps S200 to S270), and a process for determining the final position, direction and speed of each fish belonging to the group (step S300 to step S300). S340) and the like.
[0077]
First, in the processing related to the leader, the position coordinate and speed of the target object (hereinafter referred to as the target) are received, the distance from the leader to the target is generated for each pattern, and the direction to the target is set as the target direction of the leader (step S120). .
[0078]
In this embodiment, there are a lure following type and a specific area excursion type as behavior patterns of a school of fish. The lure following fish school follows the lure as a target object, and the specific area migratory fish school slowly migrates in a narrow area around a predetermined coordinate. In the present embodiment, the content of movement of the leader is determined for each pattern. The target direction is a reference value when determining the moving direction (traveling direction) and direction of each fish.
[0079]
Next, change the leader. In the present embodiment, the leader is changed when the current leader is within a certain distance from the target object and a certain time has elapsed (steps S130 and S140). Then, along with the change of the leader, the target direction of the leader is changed, and the group internal time is reset (step S140). The group internal time is a count value that is reset every time the leader is changed.
[0080]
In the process related to other than the leader, the intra-group loop process of steps S200 to S270 is performed for the number of fish belonging to the school of fish.
[0081]
First, if the fish is not a leader, the smallest one of the distances from itself to other fish is obtained. Further, a distance from the user to the leader is generated, and the direction to the leader is set as the target direction of the user (step S220).
[0082]
If the distance to the leader is close, a value (weight) obtained by multiplying the distance to the leader by a coefficient is generated, and the target direction of the player is made the same as the target direction of the leader (steps S230 to S240).
[0083]
Next, a process for preventing sticking between fish other than the leader is performed. If the distance to the leader is outside a certain range and the distance to the nearest other fish is closer than your body length, the distance from you to the nearest other fish is generated, and the nearest other fish A direction obtained by adding 180 degrees to the rotation component of Y among the above directions is set as a target direction (steps S250 and S260). In the present embodiment, the direction to the target and the reader has rotation components with respect to the three axes.
[0084]
In the process of determining the final position, direction and speed of each fish belonging to the fish school, the intra-group loop process of steps S300 to S340 is performed for the number of fish belonging to the fish school.
[0085]
First, delay processing of other fish's following behavior is performed. Other fishes slightly move their own moving direction (traveling direction) toward their target direction only when the group internal time exceeds their own weight (steps S310 to S320). In the present embodiment, the traveling direction is changed gradually in a plurality of times with the traveling direction toward the target direction.
[0086]
Then, based on the speed or acceleration of the reader, its own speed or acceleration is obtained, and the speed is corrected according to the distance from the reader (step S330). In this way, the speed can be increased so that other fish that are too far from the leader do not move unnaturally. Further, the current position is obtained from the speed, the traveling direction, and the previous position (step S330).
[0087]
Then, after the intra-group loop for each fish is completed, the group internal time is added (step S350), and the group-specific loop is terminated (step S360).
[0088]
