Description

  The present invention allows a computer to set a game space having gravity in a predetermined direction, and causes a damaged character that has received given damage to float while falling in the game space, and then returns to a return posture. The present invention relates to a program for performing control to be performed.

  In video games, when a character composed of a model having a joint structure (hereinafter simply referred to as a character) is operated, it is generally controlled according to a motion prepared in advance for each operation. However, since only one motion pattern can be expressed with one motion, a plurality of motions are often prepared for each motion in order to enable various expressions.

  As control of a character based on motion, a technique for controlling the speed of an object moving motion in accordance with an operation timing is known. Specifically, for example, in a tennis game, when the player (character) swings a tennis racket by an operation input (swing operation), if the operation timing is faster than the appropriate timing, the operation speed is reduced. (Slow speed) and fast (high speed) when slow (for example, Patent Document 1).

In a ball game system game such as baseball, a technique for correcting motion based on a deviation of a character's posture at the time of catching the ball and the positional relationship of the ball is also known. Specifically, for example, in a baseball game, when a fielder (a character) performs a catching action to catch a ball, according to the difference between the position of the glove when the fielder catches the field by the motion group and the arrival position of the ball Thus, the position of the globe in the motion based on the motion group is corrected (for example, Patent Document 2).
Japanese Patent Laid-Open No. 13-029654 JP-A-14-052422

  By the way, in a battle scene in an RPG (role-playing game), an action game, or the like, a character (damaged character) damaged by an attack performs a so-called “defeated action (defeated motion)” corresponding to the received damage. Basically, the “done action” is an action of falling (landing) after being blown after receiving damage. Depending on the damage received, for example, the attitude when landing is different and the attitude in the air is different. There are various patterns such as different or different heights and distances.

  Then, after performing the “defeated operation”, it is common to perform an operation (return operation) for returning to the battle again from the state (posture) at the time of landing. That is, it is necessary to prepare a motion for performing the return operation for each state (posture) when landing. Therefore, the more the state (posture) at the time of landing is, the more motion is required. As a result, the amount of data required for the expression of “behavior motion” and the motion associated therewith is enormous. The problem of becoming occurred.

  In view of the above circumstances, an object of the present invention is to make it possible to express a so-called “defeated motion” and a motion associated therewith in a battle scene with a smaller amount of data.

In order to solve the above problem, the first invention is:
Control that causes a computer to set a game space having gravity in a predetermined direction, causes a damaged character that has received given damage to float while falling in the game space, and then displaces it to a return posture. A program for making it happen,
An aerial movement control means (for example, an aerial movement control unit 234 in FIG. 9) that controls the movement of the damaged character in the air so that the aerial trajectory and the dwell time differ according to the received damage;
An attitude that controls the aerial attitude so that the attitude of the damaged character during the movement control by the aerial movement control means is changed to the aerial attitude and the attitude at the time of landing of the damaged character by the movement control is always a constant attitude. Control means (for example, the air attitude control unit 236A in FIG. 9),
A return control means (for example, a return motion control unit 240 in FIG. 9) that performs control for displacing the damaged character to the return posture after the damaged character has landed by movement control by the aerial movement control means;
As a program for causing the computer to function.

In addition, the ninth invention,

It is a game device provided with.

  According to the first or ninth invention, when the character to be damaged is floated in the game space (in the air) and dropped, and then displaced to the return posture, the aerial trajectory and the hover time are in accordance with the received damage. While moving differently, the aerial posture can be changed so that the posture at the time of landing always becomes a constant posture.

  Therefore, in the so-called “defeated movement” where the damaged character that has received damage is floated and dropped, the landing posture can always be a constant posture, so the motion after landing, that is, the landing posture Only one motion is required for displacing from the return posture to the return posture. As a result, it is possible to reduce the amount of data required to express the “behavior operation” and the operation associated therewith. Also, since the aerial trajectory and flight time can be changed according to the damage received, for example, the more you receive more damage, the higher the distance you fly, the more “done” action that does not increase the amount of data. It can be expressed.

The second invention is the program of the first invention, wherein

The aerial attitude can be controlled to be the final attitude. Therefore, by setting the final posture of the reference motion to an appropriate landing posture, the landing posture can be always set to this landing posture.

A third invention is the program of the second invention, wherein

  According to the third aspect, the same effect as the second aspect can be obtained, and the change speed of the aerial posture can be varied so that the posture of the damaged character at the time of landing becomes the final posture of the reference motion. . Therefore, by changing the change speed of the air attitude, the attitude at the time of landing can always be a constant attitude regardless of the flight time. Specifically, the landing posture can be made the final posture of the reference motion by increasing the change speed of the air posture as the hover time is slower and as the hover time is shorter.

  According to the fourth aspect of the invention, the same effect as the second aspect of the invention can be obtained, and after the character to be damaged is turned by the number of times based on the flight time based on the turning motion included in the reference motion, the reference motion is Can be changed from the reference posture to the landing posture based on the landing motion included in the. Further, the turning speed can be varied so that the landing posture becomes the landing posture. Therefore, since the turn can be performed by the number of times based on the flight time, for example, the longer the flight time, the greater the number of rotations can be made. Further, since the turning speed can be varied, the posture at the time when the turning is completed can always be set as the reference posture.

A fifth invention is the program of the fourth invention, wherein
The computer is configured to determine the number of times the damaged character is turned based on a turning time obtained by removing the time required for the landing posture change control by the landing posture control unit from the hover time. Make it work

  According to the sixth or tenth aspect of the present invention, when the character to be damaged is floated in the game space (in the air) and dropped, and then displaced to the return posture, the aerial trajectory and the hover time are in accordance with the received damage. While moving differently, the aerial posture can be changed at a predetermined speed according to a predetermined reference motion. In addition, when the landing posture does not become a predetermined posture, the aerial trajectory and / or the flight time can be changed so as to be a predetermined posture.

  That is, by changing the aerial trajectory and / or the flight time, the landing posture can always be a predetermined posture. Therefore, in the so-called “done action” in which the damaged character that has received damage is floated and dropped, the attitude at the time of landing can always be a constant attitude, so the action after landing, that is, the attitude at the time of landing Only one motion is required for displacement to the return posture. As a result, it is possible to reduce the amount of data required to express the “behavior operation” and the operation associated therewith. Also, since the aerial trajectory and dwell time can be changed by the damage received, the expression of “behavior movement” corresponding to the damage, such as flying more and more, the more data is received, for example, the more damage is received It becomes possible without.

  According to the seventh aspect of the invention, the character in the game space is moved in a predetermined trajectory according to the load on the character for a predetermined time, and at the end of the movement, the moving character is always kept constant. The posture of the character can be changed.

  Therefore, for example, when applied to a damaged character that has received a given damage while the game is in progress as a character, in a so-called “defeated action” in which the damaged character is floated and dropped, the posture at the end of movement, that is, the landing posture is set. Since it can always be constant, less motion is required to perform the operation after landing. Also, in this case, the received damage becomes a load on the character, and the trajectory can be changed according to the received damage, so for example, the more damage is received, the higher it is and the farther it is In addition, it is possible to express “behavioral behavior” without increasing the amount of data.

Therefore, according to the seventh aspect, by causing the computer to read the information stored in the information storage medium and executing the arithmetic processing, the same effects as in any one of the first to seventh aspects are achieved. be able to.

  According to the present invention, a so-called “defeated action” and an accompanying action in a battle scene can be expressed with a smaller amount of data.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In the following, a case where an RPG (role playing game) is executed in a home game device will be described, but the application of the present invention is not limited to this. Further, in each drawing, a character model having a joint structure (hereinafter referred to as “character”) is shown in a simplified manner as appropriate, but actually has a joint structure similar to that of a human being as shown in FIG. Or may have other complex structures.

Has been. The game controller 1110 is for a player to input a game operation, and outputs an operation signal corresponding to the operation to the main body device 1100. The player enjoys a role-playing game (RPG) by operating the game controller 1110 while viewing the game screen displayed on the display 1200.

[First Embodiment]
First, the first embodiment will be described.

<Principle>
In RPG, a player moves a player character that is an operation target within a game stage set by placing various objects such as a background and characters in a virtual three-dimensional space (game space), and generates various events. The game progresses by clearing. Then, a 3DCG image of the game space viewed from a virtual camera CM set to follow a given viewpoint, for example, a player character, is displayed on the display 1200 as a game screen.

  Here, the game space is defined by an XYZ orthogonal coordinate system in which the XZ plane is a horizontal plane, and positions, vectors, and the like described later are expressed in this XYZ coordinate system unless otherwise specified. Further, the game space is assumed to be a gravity field in which gravity acts vertically downward (Y-axis negative direction) as in the real space.

  In RPG, when a player character encounters an enemy character while moving on the game stage, the player character enters a battle mode and starts a battle with the enemy character.

  FIG. 2 is a schematic view of the game space in the battle mode. In the figure, a character CA and a character CB are fighting. Each of the characters CA and CB performs an attacking action such as singing attack magic, punching or kicking, slashing with a weapon (sword, etc.), or singing defensive magic, and has a defense posture to protect itself. Take a defense action against an opponent character's attack, such as taking an armor (shield). When the characters CA and CB are damaged by the attacking action of the opponent character, the life point (life value) is lowered according to the magnitude of the received damage. Then, the character whose life point is “zero (0)” first becomes “losing” and the battle ends.

  In the battle mode, a character (hereinafter referred to as “damaged character”) DC that has been damaged by the attack of the opponent character performs a so-called “defeated action” corresponding to the received damage. The present embodiment is characterized by the control of this “defeated operation”.

  In the “defeated action” in the present embodiment, the damaged character DC is launched upward and floats in the air, and then falls due to the action of gravity acting on the game space. FIG. 4A shows a state where the character CA attacks the character CB. That is, the character CB is the damaged character DC. As shown in FIG. 5B, the character CB, which is the damaged character DC, is launched obliquely backward by this attack and floats in the air, and then falls (lands) on the ground.

  At this time, the damaged character DC is controlled to always land in the same posture. Here, control is performed so as to land in a supine posture (a supine posture), but any posture such as a prone posture or an upside down posture (a posture landing from the head) may be used. Also, the height in the air where the damaged character DC is launched and the distance to the landing position vary depending on the damage received.

This will be specifically described.
In the control of the performed action, first, as shown in FIG. 3, an initial velocity vector V0 is set as a driving force for causing the damaged character DC to rise in the air. The initial velocity vector V0 is determined by the attack vector F and the weight W of the damaged character.

  The attack vector F is a vector representing the magnitude (strength) and direction of the attack by the attacking character (attack character; character CA in FIG. 2). The magnitude of the attack vector F is determined by the attack ability and level such as the power of the attack character, the type of attack used, and the like. The larger the attack vector F, the more damage is given to the damaged character DC.

  The direction of the attack vector F is basically set as the direction from the attacking character to the damaged character DC. For example, when a kick is performed to kick up from below, the direction of the attack vector F is substantially vertically upward. It is set appropriately according to the type of attack used.

  The direction of the initial velocity vector V0 is set substantially parallel to the direction of the attack vector F. This is to express a situation in which the damaged character DC is blown backward due to damage.

  The magnitude of the initial velocity vector V0 is set as a value obtained by correcting a value proportional to the magnitude of the attack vector F with the weight W of the damaged character DC. This is to express a situation in which the damage character DC is higher and more distant as the damaged character receives more damage or the weight W of the damaged character is lighter.

Specifically, as shown in the following equation (1), the magnitude | F | of the attack vector F is multiplied by a predetermined coefficient k, and the ratio of the weight W of the damaged character DC to the predetermined reference weight Wb. It is set as a value multiplied by ΔM (= Mb / M).
| V0 | = k × ΔM × | F | (1)
However, k ≧ 0.

  When the initial velocity vector V0 is set, a trajectory (air trajectory) AR in which the damaged character DC moves in the air is calculated based on the initial velocity vector V0.

  FIG. 4 is a diagram for explaining calculation of the aerial trajectory AR. In the figure, the position of the representative point of the damaged character DC is treated as a mass point for the sake of simplicity of explanation. As shown in the figure, when the initial velocity vector V0 (Vx0, Vy0, Vz0) is given to the damaged character DC at the damaged position (attack position) P0 (X0, Y0, Z0), the physical law is obeyed. Exercise as follows.

That is, the velocity vector V (Vx, Vy, Vz) of the damaged character DC t seconds after receiving the damage is given by the following equations (2a) to (2c).
Vx = Vx0 (2a)
Vy = Vy0−g × t (2b)
Vz = Vz0 (2c)
Where g is the acceleration of gravity acting on the game space.

From the expressions (2a) to (2c), the position P (X, Y, Z) after t seconds of the damaged character DC is given by the following expressions (3a) to (3c).
X = Vx0 × t + X0 (3a)
Y = Vy0 × t- (g × t 2) / 2 + Y0 ··· (3b)
Z = Vz0 × t + Z0 (3c)

  That is, the trajectory in the game space that can be taken by the damaged character DC is defined by the equations (3a) to (3c). And the position (landing position) Pf (Xf, Yf, Zf) where the to-be-damaged character DC lands is calculated by obtaining the intersection of this trajectory and the terrain object. Accordingly, the portion from the attack position P0 to the landing position Pf in the trajectory defined by the equations (3a) to (3c) is the aerial trajectory AR of the damaged character DC. That is, the aerial orbit AR draws a parabola.

  Subsequently, a time required for the damaged character DC to move along the aerial trajectory AR, that is, a time required for reaching the landing position Pf from the attack position P0 (arrival time) Tf is calculated. That is, in the expressions (3a) to (3c), the time t at which P (X, Y, Z) = Pf (Xf, Yf, Zf) is the dwell time Tf. For example, when the place where the battle is performed is flat (flat ground), the time t at which Y = Y0 in the equation (3b) is the flight time Tf.

When the airborne time Tf is calculated, the number of frames (the number of airborne frames) Nf corresponding to the airborne time Tf is calculated. As shown in the following equation (4), the number of stray frames Nf is calculated by multiplying the stray time Tf [second] expressed in seconds by the number of drawing frames FN per second.
Nf = Tf × FN (4)

For example, when an image is drawn at a rate of 60 frames per second, the number of stray frames Nf is given by the following equation.
Nf = Tf × 60 (4a)

  Hereinafter, Nf frames corresponding to the flight time Tf are collectively referred to as “flying frames”. In addition, the n-th frame among these stagnant frames is referred to as “frame F (n)”. However, n = 1, 2,..., Nf. The first frame F (1) is referred to as “first frame F (1)”, and the Nf-th frame F (Nf) is referred to as “final frame F (Nf)”.

  As described above, when the aerial trajectory AR and the aerial frame number Nf are calculated, the behavior of the damaged character DC is controlled based on the calculated aerial trajectory AR and the aerial frame number Nf. In the present embodiment, “movement” and “posture” which are components of the operation are controlled independently.

(1) Control of “Movement” “Movement” of the damaged character DC in the struck action is controlled along the calculated aerial trajectory AR. Specifically, as shown in FIG. 5, the position P (X, Y, Z) of the damaged character DC is calculated according to, for example, equations (3a) to (3c) for each frame during the flight time Tf. . The damaged character DC is placed at the calculated position P (X, Y, Z). In this way, the damaged character DC is controlled to “move” along the aerial trajectory AR from the attack position P0 to the landing position Pf over the flight time Tf.

(2) Control of “Position” On the other hand, the “posture” of the damaged character DC in the beating action is controlled according to a predetermined aerial posture motion. The air attitude motion is a time series of the attitudes of the damaged character DC in the air, and represents a change in attitude with respect to time t.

  FIG. 6 is a diagram illustrating an example of an aerial posture motion. The aerial posture motion is composed of a plurality of consecutive frames (M frames) with the posture in battle (battle posture) that is the posture at the start of the beat operation as the top frame and the landing posture as the final frame. The intermediate frame is set so as to gradually change from the posture of the top frame to the final frame posture (final posture).

  According to the figure, the top frame (# 1) of the aerial posture motion is a standing posture because the character is fighting in a standing posture (standing posture). Further, the final frame (#M) is in the supine posture in order to land in the supine posture. The intermediate frames (# 1 to # (M-1)) are set to a posture in the process of gradually falling backward from the standing posture to become a supine posture.

  Such an aerial posture motion is applied to the aerial frame. At this time, the first frame (# 1) and the last frame (#M) of the aerial posture motion are applied to the first frame F (1) and the last frame F (Nf) of the aerial frame, respectively. The postures in the intermediate frames F (2) to F (Nf-1) excluding the first frame F (1) and the last frame F (Nf) are determined based on the relationship between the number of frames and the number of frames. Calculation is performed by interpolating the frames (so-called intermediate frames), or the frames themselves are applied (hereinafter simply referred to as “interpolation”). The interpolation processing can be realized by using a known interpolation calculation such as linear interpolation or spline interpolation.

  FIG. 7 is a diagram illustrating an application example of the aerial posture motion. In the same figure, (a) and (c) show the attitude in the aerial frame to which the aerial attitude motion is applied, and (b) shows the aerial attitude motion itself. More specifically, (a) shows a case where the number of aerial frames Nf is smaller than the number M of frames in the aerial posture motion (Nf = Nf1 <M), and (c) shows a frame in which the aerial frames number Nf is in the aerial posture motion. The case where it is larger than the number M (Nf = Nf2> M) is shown.

  As shown in the figure, in both cases (a) and (c), the final frames F (Nf1) and F (Nf2) are in the supine posture. In other words, the posture in the final frame F (Nf) is always a supine posture, regardless of the number of stray frames Nf (that is, the length of the stray time Tf). At this time, the “posture” of the damaged character DC in the air changes faster as the number of frames Nf is smaller (that is, the flight time Tf is shorter), and the number Nf of frames is longer (that is, the flight time Tf is longer). ) It changes slowly.

  Therefore, the performed action of the damaged character DC whose “movement” and “posture” are controlled is as shown in FIG. That is, the damaged character DC moves in the air so as to draw a parabola while gradually falling backward from the standing posture at the attacked position P0 where the damage is received, and lands at the landing position Pf in a supine posture.

  As described above, in the operation to be performed, the number of frames in the airspace Nf, that is, the number of frames required to land, is calculated, and the airframe motion determined in advance is applied to the airframes having the airframe number Nf. The “posture” of the character DC in the air is controlled. Therefore, regardless of the aerial trajectory AR and the flight time Tf, it is possible to land the damaged character DC in a constant posture (here, the posture on the back).

  When the operation is completed, a return operation is subsequently performed. In the return motion, the damaged character DC returns (displaces) from the posture at the end of the beat motion (that is, the landing posture) to the predetermined return posture at the position where the beat motion ends (that is, the landing position Pf). Perform the action. Here, in order to continue the battle, an operation is performed in which the player gets up from the landing posture, which is the landing posture, and returns to the standing posture, which is the fighting posture.

  By the way, as described above, in the performed operation, the landing is always controlled in the same posture. That is, the posture at the end of the beat operation is always the same. For this reason, at least one pattern is sufficient for the return motion for controlling the return operation. That is, it is a pattern that rises from the supine posture that is the landing posture and returns to the standing posture.

<Functional configuration>
FIG. 9 is a block diagram showing a functional configuration in the first embodiment. According to the figure, the first embodiment functionally includes an operation input unit 10, a processing unit 20, a storage unit 40, an image display unit 72, and a sound output unit 74. The

  The operation input unit 10 receives an operation instruction from the player and outputs an operation signal corresponding to the performed operation to the processing unit 20. This function is realized by, for example, a button switch, lever, dial, mouse, keyboard, various sensors, and the like. In FIG. 1, the game controller 1110 corresponds to this.

  The character data 54 is data relating to a character model having a joint structure appearing in the game, and is prepared for each character.

According to the figure, the character data 54 stores a model (54a), a joint structure (54b), a weight (54c), a position (54d), and a posture (54e) in association with each other. .

  The model (54a) stores data for modeling the character in the game space. Further, texture data to be mapped is also stored here.

  The joint structure (54b) stores data on the joint structure of the character layered. Specifically, as shown in the figure, in the case of a character imitating a human being, the character is represented by the torso, head, upper right arm, right forearm, right hand, left upper arm, left forearm, left hand,. The head is connected to the body with the neck joint (joint a), the upper right arm is connected to the right shoulder joint (joint b), and the left upper arm is connected to the left shoulder joint (joint e). Further, the upper right arm is connected to the upper right arm by the right elbow joint (joint c), and the connection at the joint of each part is hierarchized and stored.

  Note that the aerial posture motion data 56A and the return motion data 58 can be applied to all characters by preparing only one type each if all characters appearing in the game have the same joint structure. However, for example, when a character imitating a human and a character imitating a bird appear, the joint structure differs between the human and the bird. It is necessary to prepare the motion data 58. Then, when controlling the performed action and the return action, the aerial posture motion data 56A and the return motion data 58 corresponding to the type of the character to be damaged DC are used.

<Process flow>
FIG. 14 is a flowchart showing a flow of processing related to “defeated operation” in the first embodiment. This process is realized when the damaged character control unit 220A executes the damaged character control program 420A of the storage unit 40. Since other game processes are publicly known, description thereof is omitted here.

  According to the figure, first, the done action control unit 230A controls the done action of the damaged character DC. That is, the frame number calculation unit 232 calculates an attack vector F based on the type of attack received (for example, punch or kick), and the initial velocity based on the attack vector F and the weight W of the damaged character DC. A vector V0 is set (step S11). Next, the trajectory in the game space that can be taken by the damaged character DC when the current position of the damaged character DC is set to the attack position P0 and the calculated initial velocity vector V0 is given at the attack position P0 is calculated (step S12). .

  Subsequently, the frame number calculation unit 232 determines the terrain of the place where the battle is being performed with reference to the stage data 52, and calculates the landing position Pf by obtaining the intersection of the determined terrain and the calculated trajectory ( Step S13). Then, the time required to move along the trajectory from the attack position P0 to the landing position Pf, that is, the hovering time Tf is calculated, and the number of hovering frames Nf corresponding to the hovering time Tf is calculated (step S14).

  Thereafter, the loop A process is executed for each frame during Nf frames corresponding to the calculated number of stray frames Nf.

  In the loop A, the aerial movement control unit 234 calculates the position P of the damaged character DC in the next frame according to the equation (3) based on the attack position P0 and the initial velocity vector V0, for example (step S15). In addition, the aerial posture control unit 236A performs an interpolation calculation based on the aerial posture motion data 56A to calculate the posture of the damaged character DC in the next frame (step S16).

  Next, the aerial movement control unit 234 places the damaged character DC at the calculated position P, and the aerial posture control unit 236A performs control so that the posture of the damaged character DC is calculated (step S17). ). Thereafter, the image generation unit 32 generates an image based on the virtual camera CM set in the game space and causes the image display unit 72 to display the image (step S18). Then, loop A ends.

  When the loop A ends, the return motion control unit 240 subsequently controls the return motion of the damaged character DC based on the return motion data 58 (step S19). Then, when the control of the return operation is finished, this process is finished.

<Action and effect>
As described above, in the first embodiment, the control of the “defeated movement” in the battle scene is performed as follows. That is, the initial velocity vector V0 is set based on the attack vector F received by the damaged character DC and the weight W of the damaged character DC. Next, an aerial trajectory AR and a landing landing position Pf on which the damaged character DC moves are calculated based on the initial velocity vector V0, and it is necessary to move from the attack position P0 to the landing position Pf along the aerial trajectory AR. The flight time Tf and the flight frame number Nf corresponding to the flight time Tf are calculated. Then, the damaged character DC is controlled to “move” along the calculated aerial trajectory AR from the attack positions P0 to Pf over the dwell time Tf, and to the Nf frame corresponding to the dwell time Tf. “Attitude” is controlled by applying aerial attitude motion.

  Therefore, the damaged character DC can always be landed in the same posture (here, the supine posture) irrespective of the received damage, that is, the aerial trajectory AR, the flight time Tf, and the like. That is, since the posture at the end of the beating operation, that is, the landing posture is always the same posture, only one motion is required for controlling the “return operation” performed following the beating operation. As a result, it is possible to reduce the amount of data required to express the “behavior operation” and the operation associated therewith.

  In addition, since the aerial trajectory AR and the flight time Tf are calculated based on the received attack vector F, for example, the more the damage is received (the greater the amount of damage), the higher the flying distance is. In addition, it is possible to express “behavioral behavior” without increasing the amount of data.

[Second Embodiment]
Next, a second embodiment will be described.
In the second embodiment, the same elements as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

<Principle>
The second embodiment is different from the first embodiment in that the damaged character DC performs an operation of moving while rotating (rotating) in the air as a defeated operation. That is, the applied aerial posture motion is different from that of the first embodiment. In addition, it is the same as that of 1st Embodiment by the point controlled to always land with the same attitude | position.

  FIG. 16 is a diagram illustrating an example of an aerial posture motion in the second embodiment. As shown in the figure, the aerial posture motion in the second embodiment is composed of (A) a turning posture motion and (B) a landing posture motion.

  The turning posture motion is a motion for causing the damaged character DC to perform a turning motion that turns in the air, and is composed of a total of M1 frames. That is, in the turning posture motion, the battle posture which is the posture at the start of the beat operation is set as the top frame (# 1), and gradually changes from this posture to turn to the top frame (# 1) again. The posture of the return process is set. Also, the posture of the last frame (# M1) is set one step ahead (one frame before) to return to the posture of the top frame (# 1) in consideration of consistency when rotating a plurality of times. In the same figure, the standing posture is the top frame (# 1), and the posture is set so that it turns to fall backward from this posture, and again comes back one step before returning to the standing posture at the last frame (# M1). ing.

  The landing posture motion is a motion for performing a landing motion for landing on the character to be damaged DC, and is composed of a total of M2 frames. That is, in the landing posture motion, the posture following the last frame (# M1) of the turning posture motion is set as the first frame (# 1), and the landing posture is set as the final frame (# M2). # 2 to # (M2-1)) are set so as to gradually change from the landing posture as the top frame (# 1) to the landing posture as the final frame (# M2). In this figure, the standing posture is set to the top frame (# 1), and the posture is set to fall back from this posture and to be the supine posture that is the landing posture in the final frame (# M2).

  In the second embodiment, such an aerial posture motion is applied to a staying frame. Specifically, as shown in FIG. 17, the turning posture motion is applied to the N1 frames from the first frame F (1) to the N1th frame F (N1) among the stagnant frames made up of Nf frames, and the following ( The landing posture motion is applied to N2 (= Nf−N1) frames from the (N1 + 1) th frame F (N1 + 1) to the last frame F (N). However, 1 <N1 <Nf.

In the present embodiment, the number of first half frames (hereinafter referred to as “turning frames”) N1 to which the turning posture motion is applied (the number of turning frames) N1 and the latter half frames (hereinafter referred to as “the turning frames”). The number of landing frames (referred to as “landing frames”) (the number of landing frames) N2 is determined by the following equations (5a) and (5b).
N2 = M2 (5a)
N1 = Nf−N2
= Nf-M2 (5b)

  That is, the landing posture motion is applied to the M2 frame in the latter half equal to the number of frames of the landing posture motion among the aerial frames composed of Nf frames, and the turning posture is applied to the remaining (Nf-M2) frames excluding this landing frame. Motion is applied.

(A) Application of Turning Posture Frame When applying the turning posture frame, first, the number of times (the number of turns) R that the damaged character DC is turned in the air is calculated. Specifically, the rotation frame number N1 is calculated by dividing the rotation frame motion frame number N1 by the rotation posture motion frame number M1. Here, when it is not divisible (the division result does not become a natural number), a value (natural number) obtained by rounding off the first decimal place of the division result is set as the rotation number R. Instead of rounding off, the first decimal place may be rounded up or down.

  For example, when the frame number M1 of the turning posture motion is “10”, if the turning frame number N1 is “20”, the turning number R is calculated as “2 (= 20/10)”. If the number N1 is “25”, the number of rotations R is calculated as “3” by rounding off the first decimal place of the division result (2.5 = 25/10).

When the number of turns R is calculated, a turn application posture motion corresponding to the number of turns R is generated. Specifically, in order to rotate the damaged character DC by the number of rotations R in the rotation operation, the rotation posture motion is connected by the number of rotations R as shown in FIG. Therefore, the frame number MR of the rotation application motion to be generated is given by the following equation (6).
MR = M1 × R (6)
In the drawing, the case where the number of rotations R is “2” is shown. Therefore, the number of frames MR of the rotation application posture motion generated in this case is “M1 × 2”.

  Then, this turning application posture motion is applied to the turning frame. At this time, the first frame (# 1) and the last frame (#MR) of the rotation application posture motion are applied to the first frame F (1) and the frame F (N1), respectively.

  FIG. 19 is a diagram illustrating an application example of the turn application motion, and illustrates a case where the turn number R is “2” (R = 2). In the same figure, (a) shows the turning applied posture motion itself, and (b) shows the posture in the turning frame to which the turning applied posture motion is applied.

  Thus, in the turning operation, the character to be damaged DC is controlled to turn by the number of turns R. The speed at which the posture changes in the turning operation changes depending on the number of turning frames N1 and the number of turns R. In other words, if the number of turn frames N1 is the same, the change is faster as the turn number R is larger, and the change is slower as the turn number R is smaller. If the number of rotations R is the same, the change is slower as N1 is larger, and the change is faster as N1 is smaller. Further, the posture of the damaged character DC at the end of the turning motion is the posture of the last frame (# M1) of the turning posture motion.

(B) Application of landing posture motion The landing posture motion is applied to the landing frame. At this time, since the number of landing frames N2 and the number of landing posture motion frames M2 are equal, each frame of the landing frame and each frame of the landing posture motion have a one-to-one correspondence. That is, the first frame (# 1) and the last frame (# M2) of the landing posture motion coincide with the frame F (N1 + 1) and the last frame F (Nf). And the speed of the posture change in the landing motion is always constant.

  Accordingly, the action of the damaged character DC whose “movement” and “posture” are controlled in the second embodiment is as shown in FIG. That is, the character to be damaged DC moves in the air while drawing a parabola while rotating backward or one turn from the attack position P0, and lands at the landing position Pf in a supine posture.

<Functional configuration>

  The number-of-turns calculation unit 238 calculates the number of turns R for turning the damaged character DC in the air. Specifically, first, the number of turning frames N1 and the number of landing frames N2 are calculated according to the equations (5a) and (5b) based on the number of stray frames Nf calculated by the frame number calculation unit 232 and the number of frames M2 of the landing posture motion. calculate. Next, the rotation number R is calculated by dividing the calculated N1 by M1.

  In FIG. 21, the aerial posture control unit 236 </ b> B controls the “posture” of the character to be damaged DC in the beating action. Specifically, first, a turn application posture motion is generated based on the turn number R calculated by the turn number calculation unit 238. That is, as shown in FIG. 18, the rotation posture motion is connected by a number equal to the number of rotations R to generate a series of motions. The generated turn application posture motion is stored in the turn application posture motion data 68.

  FIG. 23 is a diagram illustrating an example of a data configuration of the turning application posture motion data 68. According to the figure, the turn application posture motion data 68 stores a frame number (68a) and a set character posture (68b) in association with each frame constituting the turn application posture motion. ing. As shown in the figure, since the rotation application posture motion is data generated by connecting the rotation posture motions corresponding to the number of rotations R if the number of rotations R is 2 or more, the same data for each M1 frame. The content (posture) appears repeatedly.

  Then, the aerial attitude control unit 236B applies the rotation application attitude motion based on the rotation application attitude motion data 68 to the N1 frames from the first frame F (1) to the frame F (N1) among the aerial frames composed of Nf frames. To do. At this time, the frame F (1) and the frame (N1) are applied so that the top frame (# 1) and the last frame (#MR) of the rotation application posture motion match.

  Also, the landing posture motion based on the landing posture motion data 564 is applied to the N2 frames from the frame F (N1 + 1) to the final frame F (Nf). At this time, it is applied so that the top frame (# 1) and the last frame (# M2) of the landing posture motion coincide with the frame F (N1 + 1) and the last frame F (Nf).

Yes. That is, data for M2 frames, which is the number of frames of the landing posture motion, is stored.

<Process flow>
FIG. 25 is a flow chart for explaining the flow of processing related to the beating operation in the second embodiment. This process is realized when the damaged character control unit 220B executes the damaged character control program 420B of the storage unit 40.

  According to the figure, first, the done action control unit 230B controls the done action of the damaged character DC. That is, the frame number calculation unit 232 calculates an attack vector according to the type of attack received, and sets an initial velocity vector V0 based on the attack vector F and the weight W of the damaged character DC (step S31). Next, the trajectory in the game space that can be taken by the damaged character DC when the current position of the damaged character DC is set to the attack position P0 and the calculated initial velocity vector V0 is given at the attack position P0 is calculated (step S32). .

  Subsequently, the frame number calculation unit 232 determines the terrain of the place where the battle is being performed with reference to the stage data 52, and calculates the landing position Pf by obtaining the intersection of the determined terrain and the calculated trajectory ( Step S33). Then, the time required for moving along the trajectory from the attack position P0 to the landing position Pf (dwelling time Tf) is calculated, and the number of remaining frames Tf corresponding to the dwelling time Tf is calculated (step S34). .

  Next, the number of turns calculation unit 238 calculates the number of turned frames N1 and the number of landing frames N2 according to the equations (5a) and (5b) based on the calculated number of stray frames Nf. That is, the landing frame number N2 is set equal to the landing posture motion frame number M2, and the turning frame number N1 is set to a number obtained by subtracting the landing frame number N2 from the remaining frame number Nf (step S35).

  Then, the rotation number calculation unit 238 calculates the rotation number R based on the calculated rotation frame number N1 and the rotation posture motion frame number M1. That is, the turning frame number N1 is divided by the turning posture motion frame number M1. If it is not divisible, a value (natural number) obtained by rounding (or rounding up / down) the first decimal place of the division result is set as the number of rotations R (step S36).

  Subsequently, the aerial posture control unit 236B generates a rotation application posture motion by connecting a number of rotation posture motions equal to the calculated number of rotations R into a series of data (step S37).

  Thereafter, the loop B process is executed for each frame for N1 frames corresponding to the calculated number N1 of rotating frames.

  In the loop B, the aerial movement control unit 234 calculates the position P of the damaged character DC in the next frame (step S38). In addition, the aerial posture control unit 236B performs an interpolation operation based on the turning applied posture motion data 68 to calculate the posture of the damaged character DC in the next frame (step S39).

  Next, the aerial movement control unit 234 arranges the damaged character DC at the calculated position P, and the aerial posture control unit 236B performs control so that the posture of the arranged damaged character DC is calculated. (Step S40). Thereafter, the image generation unit 32 generates an image based on the virtual camera CM set in the game space and causes the image display unit 72 to display the image (step S41). Then, loop B ends.

  When the loop B ends, the process of the loop C is subsequently executed for each frame for N2 frames corresponding to the number of landing frames N2.

  In the loop C, the aerial movement control unit 234 calculates the position P of the damaged character DC in the next frame (step S42). Further, the aerial posture control unit 236B calculates the posture of the damaged character DC in the next frame based on the landing posture motion data 564 (step S43).

  Next, the aerial movement control unit 234 arranges the damaged character DC at the calculated position P, and the aerial posture control unit 236B performs control so that the posture of the arranged damaged character DC is calculated. (Step S44). Thereafter, the image generation unit 32 generates an image based on the virtual camera CM set in the game space and displays it on the image display unit 72 (step S45). Then, loop C ends.

  When the loop C ends, the return motion control unit 240 subsequently controls the return motion of the damaged character DC based on the return motion data 58 (step S46). Then, when the control of the return operation is finished, this process is finished.

<Action and effect>
As described above, in the second embodiment, the control of “defeated movement” in the battle scene is performed as follows. That is, the number of stagnant frames Nf is calculated as in the first embodiment. Next, the number of turning frames (turning frame number) N1 for making a turning operation and the number of landing frames (landing frame number) N2 for making a landing operation are determined among the staying frames composed of the number of staying frames Tf. The number of times (the number of rotations) R that the damaged character DC is rotated in the rotation operation is calculated. Then, a turn application posture motion obtained by connecting the turn posture motion by the number of rotations R is applied to the turn frame composed of the N1 frame, and the landing posture frame is applied to the landing frame composed of the N2 frame. The “posture” of the damage character DC is controlled.

  Therefore, the damaged character DC can always be landed in the same posture (here, the supine posture) irrespective of the received damage, that is, the aerial trajectory AR, the flight time Tf, and the like. That is, since the posture at the end of the beating operation, that is, the landing posture is always the same posture, only one motion is required for controlling the “return operation” performed following the beating operation. As a result, it is possible to reduce the amount of data required to express the “behavior operation” and the operation associated therewith.

  In addition, since the aerial trajectory AR and the flight time Tf are calculated based on the received attack vector F, for example, the more “damaged operation” corresponding to the damage, such as the greater the damage, the greater the distance, It can be expressed without increasing the amount of data. Furthermore, by rotating at the number of rotations R corresponding to the dwell time Tf during the movement in the air, it is possible to give diversity to the expression of “defeated movement”.

[Modification]
The application of the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

(A) In the above-described embodiment, the attitude change speed in the air is constant. In the above-described embodiment, the dwell time Tf is calculated based on the set initial velocity vector V0, and the dwell frame composed of Nf frames corresponding to the calculated dwell time Tf. By applying the aerial posture motion to the position, the posture (landing posture) at the time of landing of the character DC to be damaged is always set to a constant posture (vertical posture). That is, although the change speed of the air attitude is varied, it may be constant and the attitude at the time of landing may be always constant by changing the dwell time Tf.

Specifically, for example, in the second embodiment, the number of revolving frames N1 is changed to the number of revolving frames N1 ′ according to the following equation (7).
N1 ′ = M1 × R (7)
That is, the turning frame number N1 is changed to a multiple of the frame number M1 of the turning posture motion.

  Then, the turn application posture motion is applied to the frame having the turn frame number N1 ′. Accordingly, the frames F (1) to F (N1 ′) of the turning frame correspond to the frames (# 1) to (#NR) of the turning application posture motion on a one-to-one basis. For this reason, the changing speed of the posture of the damaged character DC in the turning motion is always constant.

At this time, the “movement” of the damaged character DC is controlled as follows.
(A-1) Do not change the aerial trajectory AR For example, the position P of the damaged character DC in each frame (frames F (1) to F (N1)) when moved by the number of turning frames N1 before the change. By interpolating, the position P ′ in each frame (frames F (1) to F (N1 ′)) when moving with the changed number of rotation frames N1 ′ is calculated. In this case, the aerial trajectory AR does not change, and the speed of “movement” of the damaged character DC changes.

(A-2) Change the aerial trajectory AR Or, according to the following equation (8), calculate the number Nf ′ of stray frames after the change.
Nf ′ = N1 ′ + N2 (8)
Next, an idle time Tf ′ corresponding to the changed number of idle frames Nf ′ is calculated according to the following equation (9).
Tf ′ = Nf ′ / FN (9)
However, FN is the number of drawing frames per second.

  Subsequently, a trajectory that draws a parabola and passes through the attack position P0 and the landing position Pf, and a trajectory in which the time required to move from the attack position P0 to the landing position Pf along the trajectory is the dwell time Tf ′. calculate. A portion of the trajectory from the attack position P0 to the landing position Pf is set as a new aerial trajectory AR, and the damaged character DC is “moved” along the aerial trajectory AR.

(B) In the case where the damage is received again during the “defeated movement” Further, in the above-described embodiment, the damaged character DC moving during the “defeated movement”, that is, moving in the air, takes damage again. Applicable when received. In this case, as shown in FIG. 26, the damaged character DC again sets the initial velocity vector V0 ′ corresponding to the damage by setting the damaged position Pd as the new attack position P0 ′. To do. Based on the reset initial velocity vector V0 ′, the aerial trajectory AR ′ and the number of stray frames Nf ′ are recalculated, and thereafter, the “movement” and “posture” of the damaged character DC are controlled based on this. To do.

(C) Damaged character DC
Further, in the above-described embodiment, the case where the two characters CA and CB battle each other has been described. However, the present invention is not limited to the case where they are directly engaged, but is attacked (fired) by a gun or the like from a distant character, for example. The same applies to a character that has received some external damage, such as a case where the user has mine buried in the ground. Further, the damaged character DC is not limited to a character such as a human but can be similarly applied to an object such as an automobile or an airplane. In this case, for example, the present invention can also be applied to a case where two airplanes collide (air collision).

(D) Game Device to be Applied In the above-described embodiment, the case where the present invention is applied to a home game device has been described. However, not only the home game device 1000 shown in FIG. The present invention can be similarly applied to various devices such as a portable game device and a large attraction device in which a large number of players participate.
