Description

  The present invention relates to a character group movement control program, a storage medium, and a game device, and in particular, a character group movement control that causes a player to directly intervene a group (group) in a three-dimensional space to express group movement and battle realistically. The present invention relates to a 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 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 a 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 the 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.
Japanese Patent No. 3163696 JP 2002-66131 A JP 2004-62676 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 a problem that characters do not spread during movement or the entire group is not displayed. This is because it becomes 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.

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 that moves based on the specified force, specific force acting means that applies a specific force to each character so that each character expresses a natural movement during the movement of the group including the leader at predetermined time intervals, the specific force Based on the above, the position calculation storage means for calculating and storing the latest position of each character, and the group display means for displaying the group including the leader on a display device.
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 ally agent characters is based on input information from an input device Group movement battle means for moving to the enemy group area and fighting, front formation means for forming the front of the leader group so that the enemy group does not pass during the battle between the leader group and the enemy group, It is made to function as an enemy ally group display means for displaying the group including the leader and the enemy group on a display device.

  The character group movement control program, the storage medium, and the game device of the present invention can display the whole without greatly disturbing the group's formation, and at the same time can appropriately express the situation where the overtaking and arrangement in the formation are switched, The movement and battle of complex groups centering on the leader character can be enjoyed dynamically by intuitive and easy-to-understand operations, and can be expressed more realistically.

The present invention realizes the purpose of dynamically enjoying the movement and battle of a complex group centered on a leader character by an intuitively easy-to-understand operation by causing the player to directly intervene the group.

Group movement battle means for moving to an enemy group area and fighting based on input information from the input device 10, so that the enemy group does not pass (intersection) during the battle between the leader group and the enemy group It functions as a front line forming means for forming a front line of a group with a leader, and as an enemy team group display means for displaying the group with a leader and the enemy group on a television monitor 8 as a display device.

  Furthermore, the program for controlling the video game of this embodiment causes the CPU block 54, which is the computer, to fight based on the input information from the input device 10 after the leader-entered group enters the enemy group. It is made to function as a friendly agent moving means for moving the remaining friendly agents.

  In addition, the program for controlling the video game of this embodiment sets a virtual boundary line behind (behind) the enemy group in the CPU block 54 which is a computer, and may be the remaining ally agent (group). ) Functions as an ally agent wrapping means that automatically wraps the remaining ally agent behind the enemy group when the imaginary boundary is exceeded.

  Furthermore, the program for controlling the video game of this embodiment uses the CPU block 54, which is the computer, to search for an enemy that the leader character searches for in the same manner as the other ally agent characters during the battle after the movement of the group including the leader. Function as a means.

Has the ally agent Kaikomi means to wrap around to the back, and the enemy ally collective display means to be displayed on the television camera 8 as a display device and the enemy population and the leader entering the population, the.

  That is, in this embodiment, a program for controlling a video game inputs a group containing a leader formed by including a CPU block 54, which is a computer, in a three-dimensional virtual space including a leader character in an agent group composed of a plurality of agent characters. A group moving means that moves based on input information from the device 10, a specification that applies a specific force to each character so that each character expresses a natural movement during the movement of the group with a leader every predetermined time Function as force acting means, position calculation storage means for calculating and storing the latest position of each character based on the specific force, group display means for displaying the group with a leader on a display device, or As a function, the leader character is moved to the center of gravity of the agent group. Zehnder moving means, to function as a. As a result, during the movement of the group including the leader, the repulsive force, the cohesive force, and the movement described above as the specific force so that all characters can express a natural movement every predetermined time (frame). Power is added.

  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 where the repulsive force is not generated 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. 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 part, 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 causes the CPU block 54, which is the computer, to function as leader moving means for moving the leader character to the center of gravity of the agent group.

  That is, as shown in FIG. 12, 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, as shown in FIG. 13, the center of the agent group is provided with a center of gravity, and the position and direction of the camera are automatically adjusted so that the center of gravity is at the center of the screen on which the center of gravity is displayed. The cohesive force (2) is applied as a force toward the center of gravity so that the position coincides with 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 to move 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)

14A and 14B, the agent character x is moving at a speed υ in the υ direction, and the speed υ in the υ 'direction (center of gravity), as shown in FIGS. 14 (A) and 14 (B). When 'is given, if a force is applied in the υ'-υ direction, it can move in the υ' direction.
Here, (υ′−υ) / dt = α is an acceleration, that is, a force directed toward the center of gravity in the case of mass 1. Further, the acceleration α does not face the center of gravity (ν ′ is the direction of the center of gravity and the direction of υ′−υ). This is different from the fact that the cohesive force (that is, acceleration) in (2) is directed to the center of gravity.

  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, during the battle of the agent group, as shown in FIGS. 15 and 16, the movement force (see FIG. 11) that moves forward in the above (3) and the avant-garde soldier of the enemy group in the above (1) Since the repulsive force acts on the group, the force of both (1) and (3) above will cause the group to be crushed and gradually spread to the left and right (especially rear guard soldiers) Therefore, the center of gravity is set for the group, and the cohesive force of (2), which is the force toward this, is applied to each character to prevent diffusion. Avant-garde soldiers who are fighting on the front line are basically processed with priority to battle, and the movement in the left-right direction of the movement force (3) above does not work (the left analog stick 50 is used). Do not move even if you tilt it sideways).

  Furthermore, the program for controlling the video game of this embodiment inputs a group with a leader formed by including a CPU block 54, which is a computer, by including a leader character in an agent group composed of a plurality of friendly agent characters in a three-dimensional virtual space. Group movement battle means for moving to an enemy group area and fighting based on input information from the device 10, the leader so that the enemy group does not pass (interlace) during the battle between the group with the leader and the enemy group It functions as front forming means for forming the front of the incoming group, and enemy friendly group display means for displaying the leader containing group and the enemy group on the television camera 8 as a display device.

  That is, as shown in FIG. 17, first, an agent character other than the user character that exists within a predetermined radius (for example, 5 m) at a viewing angle θ (for example, 90 degrees) is searched.

  Next, if the other agent character in front closest to you is an enemy agent character, the player character enters the battle state, and if not, the other agent character in front of you If the agent character is an ally agent character, the state shifts to the support state, and if not, there is no other agent character in front of him, so the state is left in the moving state.

  Here, the support state may be a method of increasing the character variables such as the attack power / defense power of the avant-garde characters in the battle state existing on the front line. In this embodiment, however, A state of waiting on the spot so that an agent character of the enemy group does not enter between each character.

  In this program processing, whether or not each character is in battle is determined by referring to a state variable stored in the RAM 62 and updated from time to time. The

  According to the above explanation, as a result, a group like the front is formed. Thus, in practice, local control is given to each agent character. As a result, the process of creating a global structure is generally called “emergent control”. The purpose of the above processing to process the front line in this way is to prevent a battle.

  In the conventional method, after the battle starts, both enemies and allies are in a turbulent state of war, so even if the process can be designed so that the group can be operated up to that point, the player will then You will not know if you are operating (units). In other words, the original form of the group (unit) is lost.

  On the other hand, if the front line of the fighting avant-garde soldiers is formed in the battle state and the rear-guard soldiers located behind (behind) turn around the cover, the mass of the group (unit) Will be clearly visible.

  When an attack button (for example, □ button 20) is pressed, the player performs an attack such as swinging down the sword only of the front guard soldiers in the group (group) currently operated. Motion is displayed.

  More specifically, an agent character in a state where there is no friendly agent character in front of his / her own eyes (the enemy agent character may or may not be present) swings the sword by pressing the □ button 20. In this case, the first row does not necessarily shake the sword. This is illustrated in FIG.

  In addition, the program for controlling the video game of this embodiment causes the CPU block 54 that is the computer to fight based on input information from the input device 10 after the leader-entered group enters the enemy group. Functioning as a ally agent moving means for moving no remaining ally agent, or setting a virtual boundary line behind the enemy group, and when the remaining ally agent crosses the virtual boundary line, the remaining The ally agent is made to function as a ally agent wrapping means for automatically wrapping the ally agent back to (behind) the enemy group.

  That is, as shown in FIG. 19, (a) on the right side and (b) on the upper side show that when the left analog stick 50 is tilted in the order of rightward and upward (or the cross direction button set 36 is in order of rightward and upward). The direction of the force acting on the rear guard soldier, that is, the moving direction is shown.

  Also, as shown in FIG. 20, after tilting the left analog stick 50 and (a) and (b), it is necessary to operate the left analog stick 50 in the downward direction. If it is necessary, the downward movement (that is, the escape) of the group main body currently in battle is overlapped and processed.

  At this time, since it is not desired to move the collective body, the downward operation of the left analog stick 50 remains the operation of moving the collective main body. Do not need. That is, an appropriate virtual boundary line is provided so as to pass behind the enemy group or inside the enemy group, and the rear guard soldier moves and exceeds the virtual boundary line by the operation of the left analog stick 50 in the direction (b). If it happens, it will automatically go behind or to the side of the enemy group and move toward the center of gravity of the enemy group (after that, it will be in a battle state).

  Here, the virtual boundary line is, for example, a line perpendicular to the line connecting the center of gravity of both the enemy group and the ally agent group, and a straight line passing through the back of the enemy group from the ally agent group body, Or, although it is not behind the enemy group, it is a line perpendicular to the line connecting the center of gravity of both, and is a straight line passing through the center of gravity of the enemy group, etc., and automatic wraparound to the extent that a certain attack is possible is possible As long as it is behind the enemy group or a line passing through the inside of the group, it may be a curved line.

  As another method for preventing diffusion of agent characters, for example, a process of preparing a virtual frame as a group shape and preventing it from protruding from the virtual frame is conceivable. However, with this method, it is difficult to move (turn around) only a part of the group that is not currently fighting.

  Therefore, the program for controlling the video game of this embodiment sets a virtual boundary line behind (behind) the enemy group for the CPU block 54, which is a computer, until the remaining ally agents cross the virtual boundary line. After the movement, it is made to function as a ally agent wrapping means for automatically wrapping the remaining ally agents behind (behind) the enemy group. For the force that circulates behind (behind) the enemy group, apply the formula of the force that acts on the leader character of [Equation 5] and [Equation 6] to each agent that wraps around, so that the platoon center of gravity is the enemy platoon center of gravity. Replace it with and act as “force to force each agent toward the center of the enemy platoon”.

  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.

  Then, after setting the wraparound virtual boundary line in the step 612 or after the platoon is stopped in the step 614, a platoon movement speed setting subroutine is executed (step 616) (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 in this embodiment can display the whole without greatly disturbing the group's formation, and at the same time express the state that the overtaking and arrangement within the formation are moderately switched. In addition, it is possible to dynamically enjoy the movement and battle of a complex group centered on a leader character by an intuitively easy-to-understand operation, and to make it more realistic.

  As a result, in this embodiment, the movement of the group can be directly intervened by the operation of the input device 10 while the movement (group) including the leader starts or moves. The operation of the input device 10 is to input the moving direction by tilting the left analog stick 50 or pressing the cross direction button set 36. Thereby, the movement of the group (group) (for example, cavalry) including the leader character can be expressed realistically. The above three forces (repulsive force, cohesive force, and moving force) always act on each character during the movement of this group, and the latest position is calculated every predetermined time (frame). It is possible to express the natural movement of the flock that does not greatly disturb the formation, although it is scattered in the formation of the leader group.

  By the way, when the group including the leader moves, the leader character is positioned at the center of the group. For example, if the character located at the head of the flock is moved to the left or right as the leader character like a flock of real birds, the leader character may be changed along with the change of the head.

  However, in this embodiment, since group movement / group battle between agent characters (soldier characters) based on the command of a specific leader character is assumed, the leader character is determined depending on the state of the group (group) with the leader. Not expected to change. For this reason, even if the leader character is at the center of the group (group) including the leader, it is not changed to be the leader character due to the above-described concept of the center of gravity.

  In addition, during the battle start / combat of the group including the leader, the front of each character in battle is formed. The left analog stick 50 (or the cross direction button set 36) is tilted upward and the group including the leader starts to move upward, then encounters an enemy group and starts a battle. Continue fighting as long as you keep pushing up. At this time, a hidden front of the agent character (avant-garde soldier) in battle is formed, and the enemy character group is prevented from passing (intersecting). On the other hand, when the left analog stick 50 is tilted downward, the group starts to escape. In this regard, in a one-on-one battle, it is a normal process, but in the case of a group, the process becomes complicated.

  Furthermore, after the leader-entered group enters the battle, the remaining friendly agent group that is not in battle can be operated. When the leader group is not in battle, the agent character behind (the rear guard soldier) is in a support state to stand by on the spot and keep the formation from breaking down significantly (so that the enemy agent character does not enter between them) When there is an input operation of the input device 10, it is possible to wrap behind the enemy group (backward).

  A virtual boundary line is set near the rear (rear) of the enemy group, and the player operates the left analog stick 50 and moves until the remaining ally agent group moves beyond the boundary line. You can even get behind the enemy group (back).

  Further, in the battle after the movement of the group including the leader, the leader character can search for an enemy (search for an enemy in the field of view not in battle and approach it) in the same manner as other teammate agent characters.

  In the present invention, the leader character can be located behind the agent group.

  Allowing a player to directly intervene a group can also be applied to other game devices.
