Description

  The present invention relates to a character group movement control program, a storage medium, and a game device, and in particular, a character that allows a player to directly intervene a group (group) in a three-dimensional space to realistically represent group movement and battle. The present invention relates to a group movement control program, a storage medium, and a game device.

  Some home video games control movement of a leader character and an agent group (group) composed of a plurality of agent characters following the leader character in a three-dimensional virtual space.

Conventionally, in the character group movement control, when another character exists in the first area, the acceleration for moving away from the other character by a predetermined distance and the leader character in the second area are followed. When there is another character that moves, the acceleration for adjusting the speed and direction of movement of the other character is a total acceleration obtained by adding each component of x, y, z in the three-dimensional virtual space, Some move each character to a target point. As a result, each character can move while changing the speed and direction according to the movement situation of other characters existing in the first or second area, and the movement movement of each character can be expressed realistically. I am letting.
In the character group movement control, a plurality of game characters are specified as specific game characters or specified when none of the first button to the fourth button for instructing the direction is pressed on the input device. The first character is moved discretely from the first region, and when the first button is pressed, the game character is moved so as to be concentrated in the vicinity of the specific game character or the specific second region. As a result, in the three-dimensional virtual space, after being separated from the specific game character or the specific first area, the first game character is different from each other in the direction toward the specific game character or the specific second area. It is possible to simultaneously specify each direction and an operation start instruction by one button operation with the buttons, thereby improving the operability with respect to the movement of a plurality of game characters and reducing the burden on the signal processing unit. Further, when any one of the second button to the fourth button is pressed, a plurality of game characters are moved together in the designated direction designated by the second button to the fourth button. Without specifying this group, the second button to the fourth button can be used as buttons for instructing the original direction, and this group can be moved. The moving operability of the can be improved. Furthermore, if the input device has a cross direction button set composed of up, down, left, and right, the first button is a down button, and the second to fourth buttons are up, left, and right buttons. Since the lower button of the cross direction button set coincides with the feeling of gathering to the player from its physical arrangement position, the lower button is a button for gathering to a specific game character. It is easy to understand, and the upper left and right buttons can be used as the original direction instruction buttons of the cross direction buttons.
Furthermore, in the character group movement control, the computer is provided with a model data providing means for applying motion data of a non-displayed 3D polygon model that operates in a 3D virtual space. Some of them function as athletic performance imparting means for imparting athletic performance to the associated character and as position calculating means for calculating the position of the character in the three-dimensional virtual space. Thereby, motion performance is imparted so that a plurality of characters constituting the group follow the vertices of the non-displayed three-dimensional polygon model, and it is not necessary to prepare a motion for each character, thereby simplifying the processing. At the same time, it is possible to express a movement like a single creature while taking a complex group shape throughout the character.
Furthermore, the character group movement control is a formation control for a battle of a group character displayed in a three-dimensional virtual space and in which a group of a plurality of characters forms an enemy friendly formation and battles each other. In some cases, the player is selected from a group of predetermined formations, and the player can intervene by operating the cross direction button set of the input device, and is divided into a plurality of small groups each having a specific formation. As a result, a plurality of characters form a formation, the situation of the entire group can be grasped by the formation, and the player can intervene for a small group having a specific formation, and a plurality of characters for each small group Can intervene about. Here, when there is no intervention to a specific platoon leader by the player's input device, the formation similar to the alignment state is maintained, and when intervention to a specific platoon leader is made, there is an intervention. The platoon changes direction of movement in response to the intervention, and the other platoons maintain the formation. Therefore, the formation of the entire unit is changed by the player's intervention.
Japanese Patent No. 3163696 JP 2002-66131 A JP 2004-62676 A JP 2002-143555 A

  However, conventionally, in the character group movement control, the inventions described in Patent Document 1 and Patent Document 3 described above do not allow the player to directly intervene the movement of the group (group), but automatically by the computer. However, since the group is moved and processed, it is suitable for watching and enjoying the strategy, but it is not suitable for enjoying the movement of the group and intervening directly in the battle scene.

  In the invention described in Patent Document 1, each character group moves while changing the speed and direction while keeping distance from each other while following the leader character. It can change, and natural movement can be expressed, but since there is no concept of the center of gravity, the characters behind the group (behind) greatly diffuse in some cases, and the entire group may not appear on the screen there were. On the other hand, in the invention described in the above-mentioned Patent Document 3, each character follows each vertex of the non-displayed whole polygon model, so that each character does not diffuse greatly and the shape of the formation is changed. However, each character has its original alignment position in the platoon (that is, the vertices specific to the character that is the target of movement), so it is basically arranged in the platoon. There was no change, and it could not be said that the movement was rich in change.

  Furthermore, in the invention described in Patent Document 2, the group can be directly operated by the cross direction button set. However, basically, it is described in Patent Document 1 that follows the leader character. Therefore, the operation that can be advanced and stopped straight across the entire group was the limit. As in the above, there is no concept of the center of gravity, so there remains the problem that characters do not spread during movement or the entire group is not displayed. Therefore, it is difficult to grasp the situation of the diffused character in the program processing, and it becomes difficult to perform operations as a group from the outside.

  Furthermore, in the invention described in Patent Document 4 above, a plurality of platoons move as a whole while maintaining their formation so that the group (group) does not protrude from the virtual frame representing the formation while moving. However, unless the player chooses one of the platoons and intervenes, it simply moves to maintain the formation, so it becomes awkward and lacks realism. In addition, this method has a drawback that once a battle is entered, each character spreads into a battle state and can no longer be processed as a separate group. In this regard, it is possible to think that after two or more groups are mixed, it is possible to combine them, but in actual battles, it is unnatural that your platoon leader is changed during battle, It was desirable to be able to handle each platoon), and improvement was desired.

The present invention is a program for controlling a video game, wherein a group including a leader formed by including a computer in a three-dimensional virtual space including a leader character in an agent group composed of a plurality of agent characters is used as input information from an input device. Group moving means for moving based on the above, a team member following means for following a group of leader agents other than the group of leaders while the group of leaders is moving, the group of leaders and the team of teammates It functions as a group display means for displaying a group on a display device.
A program for controlling a video game, wherein a group including leaders formed by including a computer in a three-dimensional virtual space including a leader character in a team of friendly agents consisting of a plurality of agent characters is based on input information from an input device Group movement battle means for moving to the enemy group area and fighting, and after the start of the battle with the leader group, the team member movement to move another team member group behind the leader group in the direction of the enemy group And means for displaying the group including the leader, the enemy group, and the friend agent group on a display device.

  The character group movement control program, the storage medium, and the game device of the present invention find an agent group of a friend who is not being operated by a player, and another agent group (including a group with a leader being operated by the player) ahead. If this happens, this agent group on the back is made to follow another agent group on the front (or a group with a leader), and if an enemy group is found, the agent group on the back will fight. As described above, autonomous behavior within an appropriate range is allowed. For example, when the player finds a group including a leader who is intervening, the player performs a follow-up action according to the intervention operation, and the player is intervening the leader. The agent group on the back is automatically turned around from the back of the enemy group toward the center of gravity of the enemy group and the enemy group in battle It can, thus, the movement and combat of complex populations, it is possible to entertain the dynamic by intuitively easy to understand operation, it is possible to express in more realistic.

The present invention realizes the purpose of dynamically enjoying the movement and battle of a plurality of groups by an intuitively easy-to-understand operation by causing the player to directly intervene each group.
Embodiments of the present invention will be described in detail and specifically with reference to the drawings.

  1 to 18 show an embodiment of the present invention.

  In FIG. 15, reference numeral 2 denotes a home video game device (hereinafter referred to as “game device”) on which a video game is executed.

  In the game apparatus 2, a game apparatus body 4 is connected to a TV monitor 8 as a display apparatus having a built-in speaker 6 and an input device 10 such as a controller pad. The game apparatus body 4 has a medium reading unit 14 (see FIG. 18) into which a recording medium 12 such as a CD-ROM or DVD can be mounted. By attaching the recording medium 12 to the medium reading unit 14, the game program and game data recorded on the recording medium 12 are automatically loaded into a storage memory (RAM) in the game apparatus body 4. The television monitor 8 displays a group (group) on the game based on input information from the input device 10. The input device 10 is for moving a group (group) or the like on the game.

  As shown in FIG. 16 and FIG. 17, the input device body 16 of the input device 10 has a start button 18 for starting a game, a game character, and a selection inquiry from the game device body 4 as an operation unit. □ button 20, Δ button 22, ○ button 24, x button 26, cross button set 36 composed of ↑ button 28, → button 30, ← button 32, and ↓ button 34, Various buttons such as a select button 38, an R1 button 40, an R2 button 42, an L1 button 44, an L2 button 46, two right and left analog sticks 48 and 50, and an analog mode switch 52 are arranged. The right analog stick 48 has a function of changing the rotation (viewpoint / direction) of the camera so as to change the position where the group (group) sees on the screen. The left analog stick 50 designates the movement direction of the group (group). The □ button 20 causes an attack such as shaking the sword of each character.

  As shown in FIG. 18, the game apparatus body 4 includes a CPU block 54 that controls the entire apparatus as a computer for executing a video game program. The CPU block 54 includes an SCU (System Control Unit) 56 that mainly controls data transfer with each unit in the game apparatus body 4, a CPU (Central Processing Unit) 58 that operates with a high-speed clock as a central processing unit, and a game apparatus. A ROM (Read Only Memory) 60 in which basic control operations of the main body 4 are stored, a RAM (Random Access Memory) that functions as a work area for the CPU 58 and temporarily stores game programs and various data recorded in the recording medium 12 62 and an internal bus 64 connecting them.

  An external bus 66 is connected to the SCU 56. The external bus 66 includes an input receiving unit 68 that receives input from the input device 10 and transfers input information to the CPU block 54, and a sub CPU (not shown) that reads a game program recorded on the recording medium 12 and reads the CPU program. 54. Image processing that includes a medium reading unit 14 such as a CD-ROM drive that transfers to 54, a CPU and VRAM that perform graphic processing, performs light source processing according to information sent from the CPU block 54, and performs rendering processing in a three-dimensional field The unit 70 and a sub CPU (not shown) are provided, and are connected to an acoustic processing unit 72 that processes acoustics such as back music and battle sounds. The input receiving unit 68 is connected to the input device 10. A television monitor 8 is connected to the image processing unit 70. The sound processing unit 72 is connected to the speaker 6 built in the television monitor 8.

  The program for controlling the video game of this embodiment is a program for controlling the video game, and includes a CPU block 54 as a computer in an agent group consisting of a plurality of agent characters in a three-dimensional virtual space. Group movement means for moving the formed leader-containing group based on input information from the left analog stick 50 of the input device 10, and during the movement of the leader-containing group, another team member agent group other than the leader-containing group is transferred to the leader It functions as an ally agent group following means for following the incoming group, and a group display means for displaying the leader-containing group and the ally agent group on the television monitor 8 as a display device.

During the movement of a group with a leader, the repulsive force, the cohesive force, and the moving force are specified as the following specific powers so that all characters can express natural movement at each predetermined time (frame). Is added.
(1) A repulsive force (a force in the diffusion direction) that is a force for avoiding a collision with another character.
(2) Cohesive force (force to gather together) that is the force toward the center of gravity of the agent group (group: unit).
(3) A moving force that is a force for moving each character in a specified direction by specifying an operation unit of the input device 10 or a program.

  Here, the predetermined time (frame) is a time unit of image processing, and is a so-called “frame” at the time of drawing. In this embodiment, the time for one frame is a vertical blanking interrupt (Vsync) that is called on the program once every 1/60 seconds (16.6 milliseconds) that coincides with the vertical blanking cycle of the television monitor 8. 2 times (1/30 seconds).

  In the above repulsive force (1), as shown in FIG. 8, for example, the repulsive force for the agent character A is in the range of a circle having a radius of about 3 m, for example, centered on the position of the agent character A. A repulsive force is generated against the agent character. This repulsive force is generated separately for each agent character.

In this case, the position of one agent character is a, the position of the other agent character is b, the repulsive force generation limit distance (the distance at which the repulsive force does not occur if it is further away) is d, and the maximum repulsive force Assuming that f is f, the following is obtained.
[Equation 1]
1 = | a−b |
v = (ab) / 1
Repulsive force = v * f * max (d-1, 0) / d
Here, v is a unit vector from a to b (only has a direction and has a size of 1). The part of f * max (d-1, 0) / d is as shown in FIG. Here, | a−b | is the absolute value of (a−b). Further, max (d−1, 0) means that the larger value of (d−1) and (0) is selected. At this time, as shown in FIG. 9, the repulsive force and the distance may change at a constant ratio, but for example, the repulsive force is changed so that the repulsive force increases more rapidly as the distance is shorter as a quadratic function. May be.

  In the cohesive force of (2) above, as shown in FIG. 10, the collective center of gravity here is the so-called mass center of gravity, and the horizontal component (x, z) coordinates of each agent character are set for each component. Add and average the coordinate values. The vertical component y is the height of the ground surface. That is, the center of gravity does not necessarily coincide with the center of a simple outer frame having a shape such as a rectangle or a circle including each agent character. For simplicity, the processing may be performed at the center of such an outer frame. However, for example, when there is one character that is far from a dense portion, the center of gravity of the flock is dense. Since it is desirable to be closer to the part that is doing, the original concept of center of gravity should still be used.

In this case, when the position of the agent character A is a, the center of gravity of the group is c, and the magnitude of the maximum cohesive force is f, the following is obtained.
[Equation 2]
v = (c−a) / | c−a |
Cohesive force = v * f

Further, in the above moving force (3), as shown in FIG. 11, for example, when the left analog stick 50 of the input device 10 is tilted obliquely left frontward as the designated direction, the current speed of the agent character is v0. Suppose that the designated moving speed is v1, the time required to change from v0 to v1 is dt, and the maximum acceleration that can be generated is acc.
[Equation 3]
v = (v1-v0) / dt
Movement force = v / | v | * min (| v |, acc)
Here, v / | v | is a unit vector. v is the acceleration. By means of min (| v |, acc), the acceleration v is prevented from exceeding the maximum acceleration acc.

  Here, in the equation of motion F = mα (F: force, m: mass, α: acceleration), the mass m of the agent character is assumed to be 1 in the three-dimensional virtual space of the game in this embodiment, and the force = Calculate considering acceleration.

  For each coordinate component (x, y, z), the forces (1) to (3) above, that is, the acceleration are obtained, and these are added for each coordinate component to obtain the total acceleration. The latest speed and the latest position of each character are calculated using Equation 4], and the latest speed and the latest position are stored in the RAM 62. It is assumed that the initial speed (that is, 0), the designated moving speed (v1 of the moving force in (3) above) and the position (coordinate values in the aligned state) before the character starts moving are given in advance. .

  Using the equation (4) below, which represents the equation of motion using the Euler method, using the velocity V0 and the position P0 immediately before (at the previous frame) at which the current total acceleration α is given, The current speed V1 and position P1 are calculated for each (x, y, z) component.

In [Equation 4] of the following mathematical formula, Δt represents the time (1/30 seconds) from the previous frame time to the current frame time, and the previous speed V0 and position P0 are stored in the RAM 62. Has been.
[Equation 4]
V1 = V0 + α · Δt
P1 = P0 + V0 · Δt + 0.5 · α · Δt2

  This is obtained for each agent character, and the agent character is drawn at the latest position P1 obtained by [Equation 4] of the above equation.

  Accordingly, the repulsive force (1) and the cohesive force (2) are contradictory, and the forces (1) to (3) change for each frame. Since the center of gravity slightly swings, the cohesive force toward the center of gravity of (2) also swings. As a result, the group can feel shaking and noisy.

  In addition, the program for controlling the video game of this embodiment may cause the CPU block 54, which is the computer, to function as a leader moving means for moving the leader character to the center of gravity of the agent group.

  That is, if the leader character is the head, the entire agent group may not be displayed (does not appear) on the screen. Also, when considering a situation where a warrior (leader character) actually moves leading an agent group, it is better for the military commander to place an escort around and take command at the center rather than at the head of the group. It is also considered realistic.

  Therefore, in this embodiment, the center of the agent group is provided with a center of gravity, and the position and direction of the camera are automatically aligned so that the center of gravity is displayed at the center of the screen, and the position of the leader character matches the center of gravity. As described above, the cohesive force (2) described above is applied as a force toward the center of gravity, and a special force (a force that causes a later-described leader character toward the center of gravity) is applied to the leader character.

  In the initial state (alignment state before the start of movement), the position of each agent character of the agent group is determined to be arranged such that the shape of the agent group is a rectangle or the like, but once the movement is started, The above three forces work while changing variously for each frame, and a specific position is determined and displayed. For this reason, the shape of the entire agent group and the positional relationship / arrangement order of each character are not constant, and can represent movements that are rich in changes like an actual group.

  At this time, there is a character running at the head of the agent group, but this character is not a so-called leader character, and a force (cohesive force of (2) above) acting toward the leader character existing at the center of gravity of the agent group is working. .

  In addition to the above three forces, the following force is applied to the leader character for each frame, and the total acceleration with the above three forces is obtained. Similarly, the above formula of the Euler method is used. [Equation 4] is used to calculate the latest speed and the latest position and store them in the RAM.

In other words, in the force that moves the leader character toward the platoon center of gravity, the position of the agent character (here, the leader character) is p, the current speed of the agent character is v0, the maximum acceleration that can be generated is acc, Assuming that the position is c, the movement speed of the platoon center of gravity is v1, and the relative speed when approaching the platoon center of gravity (= the speed of the agent character viewed from the platoon center of gravity) is f (1), the following is obtained.
[Equation 5]
f (l): When 0 ≦ 1 <d, v * 1 / d
When d <1, v
Here, v is the maximum relative speed, d is the distance at which the approach speed starts to be decelerated, and 1 is the distance between the agent character and the platoon center of gravity.

If the time required for the relative speed to reach f (1) is dt, the time is as follows.
[Equation 6]
v2 = v0−v1
1 = | cp |
v3 = (cp) / 1
v4 = ((v3 * f (1))-v2) / dt
Force directed to the platoon center of gravity = v4 / | v4 | * min (| v4 |, acc)

  However, at this stage, the direction of the agent character is not yet considered, and the agent character is grasped as a particle (mass point) having no direction. This is because the agent character also has a direction, so expressing an instantaneous change in the reverse direction becomes unnatural, and it is necessary to express the state of gradually changing the direction.

  For this reason, in this embodiment, in order to change the direction of the agent character for each frame, particle control with direction is executed by adding direction control to particle (mass point) control for the agent character. With respect to this, by using a known method (for example, Japanese Patent Application Laid-Open No. 2004-62676, which is Patent Document 3 described above), the agent character can be rotated and expressed in a direction corresponding to the traveling direction. Become.

  Further, the program for controlling the video game according to this embodiment has an input device that includes a group including leaders in which a CPU block 54 as a computer is included in an agent group composed of a plurality of agent characters in a three-dimensional virtual space. Group moving means for moving based on input information from 10; ally agent group following means for following other ally agent groups other than the leader-containing group during movement of the leader-containing group; the leader-containing group and the ally The agent group is caused to function as group display means for displaying on the television monitor 8 as a display device. In this case, to cause the team of agent agents that are the other agent groups to follow the group including the leader is to move and stop the other team of agent agents simultaneously with the group including the leader.

  In this case, there are two methods for moving the leader-containing group (units): a method of directly operating with the left analog stick 50 as a first method, and a method of automatically moving a target point by deciding a target point. There is a way.

  As shown in FIG. 12, the first method can be performed only for a unit as a group including a leader that can be operated by a player (hereinafter referred to as a corps head unit). The movement is the second method described above.

  As shown in FIG. 12, when the leader group is the “corporate head unit” and the other friendly agent unit is the “escort unit”, the guard unit moves with the center of gravity of the corps head unit as a target. Therefore, when the corps head unit moves, the escort unit also moves at the same time, and when the escort unit starts moving toward its center of gravity, and the corps head unit stops, the target becomes immobile, so the escort unit also Stop. At this time, if the movement to the target of the escort unit is permitted, it will "just overlap" with the corps head unit, so if the escort unit approaches a certain distance from the corps head unit, the movement of the escort unit will be stopped .

  Specifically, if the escort unit is a “direct attack unit”, the distance is within 20 m, and if it is a “long range attack unit”, the center of gravity is located within a distance of 30 m. Furthermore, it is assumed that the escort unit does not approach the corps head unit any further. After that, if the corps head unit resumes movement and the distance of 20-30 m or more is opened again, the escort unit also resumes movement toward the corps head unit.

  The recording medium 12 records a program that causes the game apparatus 2 to function as the group movement unit, the teammate agent group tracking unit, and the group display unit.

  The game apparatus 2 that controls the video game of this embodiment moves a group containing leaders formed by including a leader character in an agent group composed of a plurality of agent characters in a three-dimensional virtual space based on input information from the input device. Group moving means, and during movement of the leader-containing group, a friendly agent group following means for causing the other team members other than the leader-containing group to follow the leader-containing group, the leader-containing group, and the friendly agent group Group display means for displaying on a television monitor 8 as a display device.

  The program for controlling the video game in this embodiment is a group including leaders formed by including a CPU block 54 as a computer by including a leader character in a three-dimensional virtual space and a team of agent agents composed of a plurality of agent characters. Group movement battle means for moving to and fighting the enemy group area based on the input information, and after starting the battle with the leader group, other friendly agent groups behind (behind) the leader group are assigned to the enemy group. It functions as an ally agent group moving means for moving in the direction, and an enemy ally group display means for displaying the group including the leader, the enemy group, and the ally agent group on a television monitor 8 as a display device.

  For example, in the operation of the rear escort unit when an operable corps head unit starts a battle, the unit has data of “attack target” in addition to “movement target”. When an enemy group is found within a certain range of the Corps Corps (view range: for example, 30 degrees forward, 30m radius or within a circle of 40m radius), or Corps Corps When the battle starts, the enemy group is set as the “attack target”. Basically, the action of attacking the “attack target” is given priority over the action toward the “movement target”.

  That is, as shown in FIG. 13, when the corps head unit starts the battle, if the rear escort unit is a long-range attack unit, the “attack target (mostly fighting against the corps head unit” The attack begins. If the back (rear) escort unit is a "direct attack unit", it will approach as far as the attack hits (= until it touches the enemy unit). At this time, the process toward the “attack target” is prioritized over the above-described “process that prevents the corps head unit from approaching further”.

  In addition, the program for controlling the video game according to the present embodiment, the CPU block 54 as the computer, after the battle of the leader-containing group is started, the other ally agent group behind the leader-containing group is transferred to the leader-containing group. In order not to overlap with each other, it is made to function as a ally agent group wrapping means for turning around from the left and right of the group including the leader.

  In this case, as described above, if you overlap with your corps head unit before heading for the “attack target”, the back (rear) escort unit will bend around from either the left or right side so as not to interfere. take. Specifically, for example, as shown in FIG. 14, when there is an ally corps head unit in the fan shape with a radius of 30 m in front of the escort unit, first, it is about 90 degrees rightward (or leftward). Move and then move forward to get behind the enemy group (unit). If there is another escort unit ahead, it will be turned around in the same way.

  Further, the program for controlling the video game according to this embodiment provides the CPU block 54 as the computer with a virtual boundary line behind the enemy group after the start of the battle with the leader group, When another ally agent group exceeds the virtual boundary line, the other ally agent group is caused to function as a ally agent group centroid moving means for automatically moving to the centroid of the enemy group.

  In this case, as shown in FIG. 14, when a virtual boundary line is provided behind the enemy unit and the escort unit moves and crosses the virtual boundary line, the escort unit is automatically moved toward the center of gravity of the enemy unit. You may make it turn. Note that the movement of the escort unit is automatically performed. This is because, for example, a numerical value corresponding to the input value when the corps head unit that can be operated by the player moves by input from the left analog stick 50 is set as a program, for example. In the RAM 62, it is prepared in advance, or from the position relationship with the front corps head unit, those numerical values (for example, about 5 m from the end of the front corps head unit (or enemy unit) laterally) The numerical value that realizes the movement that turns toward the center of gravity of the enemy unit when it moves forward and moves beyond the virtual boundary line behind the enemy unit by calculation, etc. The movement can be expressed in the same way as the corps head unit while reading. In this case, it is processed as the moving force (3) above.

  In addition, in the above, a specific calculation formula for the wraparound after the boundary line is, for example, an expression of “the force that moves the leader character toward the platoon center of gravity” in [Expression 5] and [Expression 6] (this In this case, the force for moving each agent character of the platoon to be turned toward the enemy platoon's center of gravity is obtained), the Euler's formula of [Equation 4], and a known method (for example, Japanese Patent Application Laid-Open No. 2004-62676, which is the above-mentioned Patent Document 3) By using the method described in Japanese Patent Publication No. Gazette, it is possible to express smooth wraparound while rotating the agent character in a direction corresponding to the traveling direction. Furthermore, in this case, if considered in units of platoons instead of each agent, the formulas of [Equation 5] and [Equation 6] are applied as “the force that turns the center of gravity of the platoon to be turned toward the center of gravity of the enemy platoon” You may make it act uniformly on each agent of the platoon that wraps around the required force.

  In addition to the above-described means, the recording medium 12 can be used to store the game apparatus 2 in the collective movement battle means, the friendly agent group movement means, the enemy friendly group display means, the friendly agent group wrapping means, and the friendly agent. A program is recorded that also functions as a collective centroid moving means.

  The game apparatus 2 for controlling a video game according to this embodiment uses an enemy group based on input information from an input device in a leader-containing group formed by including a leader character in an agent group composed of a plurality of agent characters in a three-dimensional virtual space. Group movement combat means for moving to a group area and fighting, and after the start of the leader group, teammate agent group movement means for moving other team agent groups behind the leader group in the direction of the enemy group , After the start of the battle with the leader group, ally agent group wrapping means for wrapping other team agent groups behind the leader group from the left and right of the leader group so as not to overlap the leader group. After the start of the battle with the leader group, a virtual boundary behind the enemy group A ally agent group centroid moving means for automatically moving the other ally agent group to the centroid of the enemy group when another ally agent group other than the leader group exceeds the virtual boundary line And an enemy ally group display means for displaying the group including the leader, the enemy group and the ally agent group on a television monitor 8 as a display device.

  Next, with regard to the operation of the game apparatus 2 of this embodiment, referring to the flowcharts of FIGS. 1 to 7, after the group of players (leader group: ally unit) moves, the computer (CPU block 54) side The case of fighting with a group (enemy group: enemy unit) will be described.

  Note that it is assumed that the game program and game data in which the recording medium 12 has already been inserted are stored in the RAM 62 in the CPU block 54 and the initial setting process has been performed in the game apparatus body 4. In addition, in order to simplify the description, in the flowcharts of FIGS. 1 to 7, the operations of the group of players are mainly described, and the description is omitted because the same processing is performed for the group of computers. did.

  As shown in the flowchart of FIG. 1, when the program starts (step 102), first, initialization is performed (step 104). The initial setting in this step 104 is that each platoon is in a movement stopped state, and the barycentric coordinates of each platoon are set. In other words, all the data such as the velocity / acceleration of all the agent characters are set to 0, facing north (example), the movement stop state of the agent characters, and polygon data are loaded. The movement stop state is a state of movement or stop.

  Then, after this initial setting, it is determined whether or not an interrupt has occurred (step 106). As described above, this time interval is a time of one frame corresponding to two vertical blanking interruptions in this embodiment.

  If step 106 is NO and no interruption has occurred, main processing is performed (step 108).

  In the main process in step 108, for example, the input information received by the left analog stick 50 and transferred after reception by the input receiving unit 68 is temporarily stored in the RAM 62 and updated as needed. Other processing for input information by pressing other buttons and processing such as sound processing for causing the sound control unit 72 to synthesize game sound effects are also executed here.

  On the other hand, if step 106 is YES and an interruption has occurred, a subroutine for group movement battle processing is executed (step 110).

  Then, after the main processing at step 108 or after execution of the group movement battle processing subroutine at step 110, it is determined whether or not the end button of the input device 10 is pressed (step 112). If step 112 is NO and the end button is not pressed, the process returns to step 106. On the other hand, if step 112 is YES and the end button is pressed, the program ends. Step 114).

  In the group movement battle processing subroutine in step 110 of FIG. 1, as shown in the flowchart of FIG. 2, one platoon state variable for each platoon and one agent state variable for each agent character are prepared in the RAM 62. Yes.

  As shown in the flowchart of FIG. 2, when the program starts (step 202), it is first determined whether or not all platoons are finished (step 204).

  If step 204 is NO and all platoons have not ended, an agent processing subroutine is executed (step 206), and a platoon processing subroutine is executed (step 208). return.

  On the other hand, if step 204 is YES and all platoons have been completed, a full screen display process is performed for characters that can be displayed in the screen frame (step 210), and the program is returned (step 212). .

  In the agent processing subroutine in step 206 of FIG. 2, when the program starts (step 302), as shown in the flowchart of FIG. 3, first, it is determined whether or not all agent characters have ended (step 304).

  If this step 304 is NO and all the agent characters have not ended, the agent state processing subroutine is executed (step 306), then the repulsive force is calculated (step 308), and the above ( The cohesive force of 2) is calculated (step 310), and it is determined whether the agent character is in a battle state (step 312).

  If this step 312 is NO and the agent character is not in a battle state, it is determined whether or not the player is operating the platoon (step 314). This step 314 is YES and the player is operating the platoon. In this case, the moving speed of the agent character is set from the inclination value of the left analog stick 50 (step 316).

  On the other hand, if step 314 is NO and the player is not operating the platoon, the moving speed of the agent character is set from the moving speed of the platoon (step 318).

  After setting the moving speed of the agent character in the step 316 or the step 318, the moving force (3) is calculated (step 320).

  After calculating the moving force in step 320, a gravity force processing subroutine is executed (step 322), the total acceleration is calculated (step 324), and the latest speed and the latest position of each character are calculated. Is stored in the RAM (step 326), and body orientation processing is performed (step 328), and the process returns to step 304.

  If step 312 is YES and the agent character is in a battle state, an agent battle process is executed (step 330). Here, for example, when the □ button 20 is pressed, only the agent character in battle starts the attack action, the enemy agent character damage process, and conversely, the enemy agent character attacks. Damage processing, defense processing, and the like when it is received are executed, and then the total acceleration is calculated in step 324.

  On the other hand, if step 304 is YES and all the agent characters have been completed, the program is returned (step 332).

  In the agent status processing subroutine in step 306 of FIG. 3, the agent status variable is changed as shown in FIG.

  As shown in the flowchart of FIG. 4, when the program is started (step 402), first, an agent character that is in front of you is searched (step 404), and whether an enemy group (enemy agent character) is found. Is determined (step 406).

  If this step 406 is NO and no enemy group has been found, it is determined whether or not an ally agent group has been found (step 408).

  If this step 408 is YES and a team of friendly agents is found, it is determined whether or not the platoon is in a battle state (step 410).

  If this step 410 is YES and the own agent group (platoon) is in the battle state, it enters the support standby state (step 412).

  If step 408 is NO and no friendly agent group has been found, or if step 410 is NO and your platoon is not in combat, there is no agent character in front of you. The movement is stopped (step 414).

  If step 406 is YES and an enemy group (enemy agent character) is found, a battle state is set (step 416).

  Then, after each processing of step 412, step 414 or step 416, the program is returned (step 418).

  In the subroutine of gravity force processing in step 322 in FIG. 3, when the program starts (step 502), as shown in FIG. 5, it is first determined whether or not the character is a leader character (step 504).

  If this step 504 is YES and the character is a leader character, the force toward the center of gravity of his platoon (a group of friendly agents) (the force obtained by the above equations [Equation 5] and [Equation 6] Is a force that is directed toward the center of gravity of the platoon, which is different from the cohesive force of (2) above (step 506).

  If step 504 is NO and the character is not a leader character, it is determined whether or not the position of the agent character exceeds the virtual boundary line (step 508).

  If this step 510 is YES and the position of the agent character exceeds the virtual boundary line, the force toward the center of gravity of the enemy platoon (enemy group) is calculated (step 510). Strictly speaking, the force is directed toward the center of gravity of the enemy platoon in the same manner as above.

  Then, after calculating the force to be directed toward the center of gravity of the platoon in step 506, after calculating the force to be directed toward the center of gravity of the enemy platoon (enemy agent group) in step 510, the step 508 is performed. If NO and the position of the agent character does not exceed the virtual boundary line, the program is returned (step 512).

  The platoon processing subroutine in step 208 of FIG. 2 includes an updated portion of the platoon state variable, as shown in the flowchart of FIG.

  As shown in the flowchart of FIG. 6, when the program starts (step 602), first, the center of gravity coordinates of its own platoon are calculated (step 604), and it is determined whether or not all agent characters are present (step 606).

  If this step 606 is NO and not all agent characters, it is determined whether or not the agent character is in a battle state (step 608). If this step 608 is NO and the agent character is not in a battle state, the above step is performed. Return to 606.

  If step 608 is YES and the agent character is in the battle state, the platoon is set in the battle state (step 610), and a wraparound virtual boundary line is set (step 612).

  On the other hand, if step 606 is YES and all agent characters are present, the platoon is placed in a stopped state (step 614). Here, this state is entered when there is no agent character in the battle state.

  After setting the virtual boundary line of the wraparound in the step 612, or after setting the platoon to be stopped in the step 614, a subroutine for setting the platoon movement speed is executed (step 616), and the program (Step 618).

  In the flowchart of FIG. 6, when any agent character enters the battle state, the state variable of the platoon to which the agent character belongs is changed to the battle state, and the boundary line of the wraparound to the enemy platoon (enemy group) is shown. Set and remember. When any agent character is no longer in a battle state, the platoon is changed to a movement stop state.

  In the subroutine of the platoon movement speed setting process in step 616 of FIG. 6, when the program starts (step 702), as shown in the flowchart of FIG. 7, first, the closest front of one's ally platoon (ally agent group). A search is made for another enemy platoon (enemy group) located in (step 704), and it is determined whether an enemy platoon (enemy group) has been found (step 706).

  If this step 706 is NO and no enemy platoon has been found, it is determined whether an ally platoon has been found (step 708).

  If this step 708 is YES and a friendly platoon is found, it is determined whether or not this friendly platoon is in a battle state (step 710).

  If this step 710 is YES and the friendly platoon is in a battle state, it is determined whether or not the enemy platoon has crossed the virtual boundary line (step 712).

  If this step 712 is YES and the ally platoon has crossed the virtual boundary line, the moving speed toward the center of gravity of the enemy platoon (around) is set (step 714).

  On the other hand, if step 706 is YES and an enemy platoon is found, a moving speed / direction approaching the enemy platoon is set (step 716).

  If step 708 is NO and no ally platoon is found, the moving speed and direction for deceleration stop are set (step 718).

  If step 710 is NO and the ally platoon is not in a battle state, the moving speed and direction following the ally platoon are set (step 720).

  If step 712 is NO and the friendly platoon does not exceed the virtual boundary line, the moving speed / direction toward the enemy platoon is set (step 722). The vicinity of the enemy platoon is, for example, a position 5 m on the boundary line from the position of the rightmost agent character of the enemy platoon.

  Then, after completion of the various settings in steps 714 to 722, the program is returned (step 724).

  As a result, the character group movement control program, the storage medium, and the game apparatus of this embodiment include an agent group that is not being operated by the player, or another agent group that is in front of the player group (including a group with a leader that is being operated by the player). If the enemy group is found, the agent group of the rear side is followed by the agent group (or leader group) of the front side. For example, when a player finds a group with a leader who is intervening, the player performs a follow-up action according to the intervention operation, Spontaneously wraps behind the enemy group from behind the enemy group toward the center of gravity of the intervening leader group and the enemy group in combat In it is possible to fight back. This makes it possible to display the whole without greatly disturbing the group's formation, and at the same time express the situation where the overtaking and placement within the formation are moderately changed. Can be enjoyed dynamically by an intuitive and easy-to-understand operation, and can be expressed more realistically.

  Further, in the input device 10, for the operation of the analog stick, not the button, the movement of the finger between the buttons is eliminated, the left analog stick 50 is moved straight in the tilted direction, and the finger is moved in another direction without releasing the finger. When tilted, complex operations such as the entire group starting to rotate around are possible.

  In addition, other friendly agent groups (eg, rear infantry groups) other than the operating group (eg, cavalry group) follow (move simultaneously and stop simultaneously), keeping the distance between the centers of gravity constant. Can keep.

  In the present invention, the ally platoon acting autonomously may be displayed on the selection screen so that the player can select it. Thereby, it becomes possible to make the other platoon of liking follow the platoon in which the player is intervening.

  It is also possible to position the leader character behind the agent group.

  Allowing the player to directly intervene each group can also be applied to other devices.
