Description

  The present invention relates to a program or the like for causing a computer to generate an image of a game space and controlling the progress of the game.

  Currently, in 3D games, there is a demand for the generation of more realistic game images in order to improve the player's virtual reality. As a technology that meets this demand, for example, an integrated model of an airplane is assembled into a group of subparts. There is known a technology that expresses how this airplane breaks by replacing the subpart configuration model by and dropping each subpart. At this time, a more realistic destructive expression is realized by substituting different sub-part configuration models depending on the degree of destructiveness. Moreover, it becomes possible to implement | achieve with a small processing load by replacing | excluding only the site | part destroyed in the integral formation model by the subpart structure model (for example, refer patent document 1). In addition, a technique is known in which an object that simulates a building is configured by a plurality of display elements that resemble block blocks, and these display elements are separated and dropped to realize the expression of the collapse of the object (for example, , See Patent Document 2).

Japanese Patent No. 3245142 JP 2000-113225 A

  However, in the technique of the above-mentioned patent document 1, the airplane etc. which fly in the air are object, The destruction is expressed because the replaced subpart falls by the dead weight etc., for example. Similarly, in the technique of the above-described Patent Document 2, the display element is separated and dropped to express destruction. For this reason, for example, it is not suitable for an expression that an object is blown up and fragments are scattered.

  The present invention has been made in view of the above circumstances, and an object thereof is to realize a realistic expression of destruction of an object by a new method.

The first invention for solving the above-described problems is
A program for causing a computer to generate an image of the game space and controlling the progress of the game (for example, the game program 410 in FIG. 16),
A moving force imparting region (at least one of a given moving speed, moving acceleration, and moving force (hereinafter collectively referred to as “moving force”) for giving each fragment object in the fragment object group ( For example, after generating the destructive force field 80 in FIG. 16, the moving force applying region control means (for example, the destructing control unit 215 in FIG. 16; step B13 in FIG. B47),
Scattering control means (for example, a destruction control unit 215 in FIG. 16) that performs a control to impart a moving force to each of the fragment objects and to scatter based on the movement force application area that is inflated by the movement force application area control means. 41, steps B19 and B27) of FIG.
As a program for causing the computer to function.

In addition, the sixteenth invention
After generating a moving force applying region for applying a given moving force to each fragment object in the fragment object group, a moving force applying region control means (for example, the destruction shown in FIG. 16) performs control for expanding the moving force applying region. Control unit 215),
Scattering control means (for example, the destruction control unit 215 in FIG. 16) that performs a control of applying a moving force to each of the fragment objects and causing them to scatter based on the moving force applying area that is inflated by the moving force applying area control means. When,
Is a game device (for example, the game device 1000 of FIGS. 1 and 16).

  According to the first or sixteenth aspect, the moving force is applied to each of the fragment objects of the fragment object group and scattered based on the expanding moving force applying region. Thus, a new expression of destruction of the object is realized such that the moving force is applied to each of the fragment objects based on the expanding moving force applying region and controlled so as to be scattered.

The second invention is the program of the first invention,
The moving force applying area control means causes the computer to function to control the moving force applying area to be extinguished or reduced after being inflated to a given size or from the occurrence to a given elapsed time. It is a program for.

  According to the second aspect of the present invention, the movement force applying region is extinguished or reduced after being expanded from a given size or occurrence until a given elapsed time has elapsed. As a result, when a certain amount of time has elapsed since the generation of the moving force application region, the expansion is terminated, and the moving force applied to each fragment object is reduced or zero, and the destruction ends.

The third invention is the program of the first or second invention,
The scattering control unit is a program for causing the computer to function so as to apply a moving force in the expansion direction at the position of the moving force applying region to a fragment object positioned in the moving force applying region.

  According to the third aspect of the invention, the moving force in the expansion direction at the position is applied to the fragment object positioned in the moving force applying region. As a result, it is possible to express the destruction such that the destruction target object breaks around a part thereof and each piece object scatters from the center toward the periphery. Also, at this time, by changing the expansion direction, speed, and shape of the moving force application region, the number of scattered objects to which the moving force is applied and the scattering direction of each debris object are changed. It is possible to express the situation.

The fourth invention is the program of the third invention,
The scattering control means varies the magnitude and / or direction of the moving force applied based on the position in the moving force applying region, and applies the moving force to the fragment object located in the moving force applying region. Is a program for causing the computer to function.

  According to the fourth aspect of the invention, the magnitude and / or direction of the moving force applied to the fragment object is varied based on the position in the moving force applying region. That is, since the magnitude and direction of the moving force applied to each fragment differ depending on the position, the degree of scattering differs for each fragment object. Thereby, it is possible to express a state in which the degree of destruction differs depending on the part of the object to be destroyed.

The fifth invention is the program of the fourth invention,
The scattering control means is a program for causing the computer to function so as to apply a greater moving force as it is closer to a central portion in the moving force applying region.

As a result, the closer to the center of the moving force application region, the greater the acceleration or speed will fly, and the further away from the center, the smaller the acceleration or speed will fly, with the center of the moving force applying region as the center (explosive). The state of destruction can be expressed.

The sixth invention is the program of the first invention,
The movement force application area control means causes a movement force application object representing the movement force application area to appear and performs control to expand the movement force application object,
The scattering control means diffuses each fragment object of the aggregated fragment object group by scatteringly controlling the fragment objects that have contacted the movement force applying object controlled by the movement force applying region control means in the expansion direction. To control to scatter,

  According to the sixth aspect of the present invention, the movement force application object representing the movement force application area appears, and the fragment object that has contacted the expanded movement force application object is controlled to be scattered in the expansion direction. Each debris object of the object group is scattered so as to diffuse.

7th invention is the program of 6th invention,
The moving force application area control means is a program for causing the computer to function so that the moving force application object appears invisible.

  According to the seventh aspect, the moving force application object appears as invisible. As a result, since the moving force imparting object cannot be visually recognized, more natural expression of destruction is possible.

The eighth invention is the program of the sixth invention,
The moving force application region control means is a program for causing the computer to function so as to gradually increase the transparency after the moving force application object appears.

According to the eighth aspect, the transparency of the moving force applying object is gradually increased.
As a result, for example, an object that simulates blasting such as a bomb or an object that simulates a fireball appears as a moving force imparting object, and after the appearance, destruction effects such as gradually increasing the transparency and making it invisible can be performed.

A ninth invention is a program according to any one of the first to eighth inventions,

It is a program to make it.

  According to the ninth aspect, the magnitude of the moving force applied by the moving force applying region is varied according to the elapsed time since the occurrence. As a result, for example, the maximum moving force immediately after the generation of the moving force applying region is maximized, and thereafter, the moving force is gradually decreased with the passage of time. After this happens, a natural expression of destruction is realized in which the momentum gradually weakens.

The tenth invention is the program of any one of the first to ninth inventions,

  According to the eleventh aspect, the fragment object group to be replaced is varied depending on which object the selected destruction target object is. As a result, for example, it is replaced with a fragment object group consisting of fragment objects corresponding to the material constituting the destruction target object such as brick, concrete, or iron, or a fragment object having a size corresponding to the fragility of the destruction target object. More natural destruction is realized by replacing with a fragment object group consisting of.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following, the case where the present invention is applied to a battle game in a home-use game apparatus will be described, but embodiments to which the present invention can be applied are not limited thereto.

[Appearance of game device]
FIG. 1 is a diagram illustrating an example of an appearance of the game apparatus 1000 according to the present embodiment. As shown in the figure, the game device 1000 includes a main body device 1110, a game controller 1120 having direction keys 1121 and button switches 1122 for a player to input a game operation, and a display 1130 having a speaker 1131. The game controller 1120 is connected to the main apparatus 1110, and the display 1130 is connected to the main apparatus 1110 by a cable 1101 that can transmit an image signal and a sound signal.

  Game information including programs and data necessary for the main unit 1110 to perform game processing is stored in, for example, a CD-ROM 1112, a memory card 1113, an IC card 1114, etc., which are information storage media detachable from the main unit 1110. Has been. That is, the player can enjoy different games by exchanging the CD-ROM 1112 and the like. The game information or the like may be acquired from an external device by connecting to the communication line N via the communication device 1115 included in the main device 1110.

  The main unit 1110 includes a control unit 1111 having a memory such as a CPU, ROM, and RAM, and an information storage medium reader such as a CD-ROM 1112. The main device 1110 executes various game processes based on the game information read from the CD-ROM 1112 or the like and the operation signal from the game controller 1120, and generates an image signal of the game screen and a sound signal of the game sound. Then, the generated image signal and sound signal are output to the display 1130 so that the game screen is displayed on the display 1130 and the game sound is output from the speaker 1131. The player enjoys the battle game by operating the game controller 1120 while listening to the game sound output from the speaker 1131 while watching the game screen displayed on the display 1130.

  In the battle game of this embodiment, the game space is configured by arranging ground objects such as buildings, bridges, and steel towers on topography such as the ground and mountains. Players operate tanks on the terrain or fighter planes that fly in the air and fire missiles (bullets) to destroy ground objects such as fighter planes, tanks, and military facilities belonging to the enemy army. To do. The ground object is destroyed when a moving body such as a missile collides, and this embodiment is characterized by this “destruction”.

[Principle of destruction]
FIG. 2 is a diagram showing an outline of “destruction” of an object in the present embodiment. According to the figure, first, the destruction target object 10 that is an object to be destroyed is replaced with a destruction object 40. As shown in FIG. 3, the destructive object 40 is a debris object group composed of a plurality of debris objects (hereinafter simply referred to as “debris”) 50, and is formed in a state in which the debris 50 are gathered. 2 and 3, the destructive object 40 is formed by integrally forming a plurality of pieces 50 and has the same shape and size as the destructible object 10 in FIGS. Although shown, it does not have to be an integrated object having the same shape and size as the object 10 to be destroyed. For example, it may be an object in which a plurality of pieces 50 are gathered at a constant density within a certain short distance range, or may be different in shape and size from the object 10 to be destroyed.

  Next, a destructive force field 80 is set. The destructive force field 80 is a moving force imparting region that cumulatively applies the moving force Fa to each piece 50 located in the force field at a predetermined processing time interval, and is a spherical region in the present embodiment. Then, the breaking force field 80 is set so that the center position O of the sphere coincides with the center position of the destruction target object 10 defined as the breaking center position.

  Subsequently, the debris 50 to which the moving force Fa by the destructive force field 80 is given is specified. Specifically, it is determined that at least a part of the fragments 50 constituting the destruction object 40 is provided with the moving force Fa by the destruction force field 80. Then, a moving force Fa by the breaking force field 80 is given to each identified piece 50. Specifically, a moving force Fa having a predetermined magnitude from the center position O of the breaking force field 80 toward the representative point Q of the piece 50 is given to the piece 50. Thereafter, movement control according to the physical law is performed on each of the pieces 50 constituting the destruction object 40. That is, each piece 50 on which the breaking force field 80 acts is moved based on the moving force Fa given by the breaking force field 80, the mass M of the broken piece 50, gravity, and the like. Further, when a collision or the like occurs due to the movement of each of these pieces 50, the movement calculation of the pieces 50 due to the collision is performed.

  Here, the destructive force field 80 changes with time. Specifically, as shown in FIG. 4, the magnitude gradually increases (expands) with time, and the moving force Fa acting on the destruction object 40 gradually decreases. That is, FIG. 5A shows the breaking force field 80 after the time t1 has elapsed since the occurrence. The magnitude of the breaking force field 80 is such that the radius R of the sphere is “R1”, and the magnitude of the moving force Fa acting is “Fa1”. FIG. 5B shows the breaking force field 80 after the time t2 (> t1) has elapsed since the occurrence. The magnitude of the breaking force field 80 is such that the radius R of the sphere is “R2 (> R1)”, and the magnitude of the acting moving force F is “Fa2 (<Fa1)”. The destructive force field 80 disappears after a predetermined time has elapsed from the occurrence. Therefore, each piece 50 moves so as to scatter in all directions from the destruction center position O toward the expansion direction of the breaking force field 80.

  In the battle game of the present embodiment, the ground object arranged on the ground surface is a composite object formed by integrating a plurality of part objects (hereinafter simply referred to as “parts”). When this composite object is destroyed, the parts to be destroyed (hereinafter referred to as “parts to be destroyed”) are specified for each part constituting the composite object, and the specified parts to be destroyed are “destroyed”. The

  Furthermore, other parts collapse (secondary destruction) with this destruction. At this time, the parts that collapse with destruction are determined based on the positional relationship between the parts. Specifically, other parts that are adjacent in the “upper”, “lower”, and “lateral” directions of the part to be destroyed collapse. In addition, there are two types of collapse: “complete destruction” in which the entire part breaks down as in the case of destruction, and “half destruction” in which only a part of the part collapses. More specifically, parts that are adjacent in the upward direction are “completely destroyed”, and parts that are adjacent in the downward and lateral directions are “semi-destructed”. Here, the positional relationship in the vertical and horizontal directions between the parts is a positional relationship in a state where these parts are integrally formed in a game space in which the weight direction with respect to the ground surface is vertically downward.

  FIG. 5 is a diagram for explaining “collapse” based on the positional relationship in the vertical direction, and shows an example of the composite object 20A. According to FIG. 5A, the composite object 20A is arranged on the ground surface GR and is integrally configured by two parts 30a and 30b. Specifically, the part 30a is adjacently arranged above the part 30b. Then, when any part 30 constituting the composite object 20A is destroyed as a part to be destroyed, the part 30 adjacent to the lower part of the part to be destroyed is “half-destructed” and the upward direction of the part to be destroyed The part 30 adjacent to “is completely destroyed”.

  For example, as shown in FIG. 5B, when the part 30a is “destroyed” as a part to be destroyed, the part 30b adjacent in the downward direction of the part 30a is “semi-destructed”. Specifically, the part 30a is replaced with the destruction object 40, and the part 30b is replaced with the half-destruction object 70 as a part to be partially destroyed.

  The half-destroying object 70 is an object having a shape in which a part of the part 30 is partially destroyed as shown in FIG. Further, the half-breaking object 70 includes an upper half-breaking object 71 having a shape in which the upper part of the part 30 is half-broken and a horizontal half-breaking object 72 having a shape in which the side part of the part 30 is partially broken. The part 70 adjacent to the part to be destroyed is replaced with a semi-destructive object 70 having a semi-destructed shape. That is, in FIG. 5B, the part 30b is adjacent to the part 30a, which is the part to be destroyed, at the upper part, and thus is replaced with the upper half-breaking object 71 whose upper part is partially broken.

  Next, a destruction process is performed on the replaced destruction part 30. That is, as described with reference to FIG. 2, the destructive force field 80 is set, and the moving force Fa based on the set destructive force field 80 is given to each piece 50 of the destructive object 40. Then, based on the applied moving force Fa, each piece 50 of the destructive object 40 is controlled to move. As a result, in the case of FIG. 5B, only the semi-destructive object 70 remains.

  Further, as shown in FIG. 5C, when the part 30b is “destructed” as a part to be destroyed, the part 30a adjacent in the upward direction of the part 30b is “completely destroyed”. Specifically, first, the part 30b is replaced with the destruction object 40, and the destruction processing is performed on the replaced destruction object 40. Next, when the part 30a falls and reaches the position where the part 30b was located, that is, reaches (contacts) the ground surface GR, the part 30a is made a part to be completely destroyed and replaced with the object 60 for complete destruction. The collapse process for the object 60 is performed. As shown in an example in FIG. 7, the total destruction object 60 is a fragment object group including a plurality of pieces 50, similar to the destruction object 40. It may not be the target).

  FIG. 8 is a diagram for explaining the principle of “collapse”. According to the figure, “collapse” is performed in the same manner as “destruction”. That is, the complete destruction target part 30 is replaced with the total destruction object 60, and then the collapse force field 90 is set. Similar to the breaking force field 80, the breaking force field 90 is a spherical moving force application region that applies a moving force Fb to each fragment 50 of the total breaking object 60. The collapse force field 90 expresses collapse due to falling, so that the center position O is set to the position of the center position of the lower surface of the total destruction target part 30 determined as the collapse center position, for example. Subsequently, among the pieces 50 constituting the total destruction object 60, the pieces 50 located in the collapsing force field 90 are identified as the pieces 50 to which the moving force Fb is applied, and the collapsing force field is assigned to the identified pieces 50. The moving force Fb by 90 is given. Then, based on the given moving force Fb, mass M, gravity and the like, the movement of each piece 50 and other parts 30 is controlled in accordance with the laws of physics.

  In the same manner as the destructive force field 80, the collapse force field 90 gradually increases in magnitude (spherical radius R) as the time elapses, and the applied moving force Fb gradually decreases. Disappears over time. As shown in FIG. 9, the collapsing force field 90 determines the collapse center position at the position where the part 30 to be destroyed falls and contacts the ground surface GR, and matches the center position O with the collapse center position. It may be set.

  In addition, when a plurality of parts are located above the destruction target part among the parts constituting the composite object, each of the plurality of parts located in the upward direction is chained along with the destruction of the destruction target part. “Collapse” and “total destruction”.

  FIG. 10 is a diagram for explaining chain “collapse” of a plurality of parts accompanying “destruction”. According to FIG. 5A, the composite object 20B is composed of three parts 30a to 30c. That is, the part 30b is arranged adjacent to the upper part of the part 30c, and the part 30a is arranged adjacent to the upper part of the part 30b.

  Then, as shown in FIG. 5B, when the part 30a is destroyed as a part to be destroyed, the part 30b adjacent in the downward direction of the part 30a is “half broken”. That is, the part 30a is replaced with the destructive object 40, and the part 30b is set as a semi-destruct target part and is replaced with the semi-destructive object 70, and the destructive process is performed on the replaced destructive object 40. As a result, the part 30c and the semi-destructive object 70 arranged in place of the part 30b remain.

  Further, as shown in FIG. 5C, when the part 30b is destroyed as a part to be destroyed, the part 30a adjacent to the upper part of this part 30b is “completely destroyed” and the part C adjacent to the lower part is "Semi-destruct". That is, the part 30b is replaced with the destructive object 40, and the part 30c is set as a semi-destruct target part and is replaced with the semi-destructive object 70, and the destructive process is performed on the replaced destructive object 40. Next, when the part 30a falls and comes into contact with the upper surface of the semi-destructive object 70, the part 30a is set as a complete destruction target part and is replaced with the full destructive object 60. Then, a collapse process is performed on the replaced object 60 for total destruction. As a result, only the semi-destructive object 70 arranged replacing the part 30c remains.

  Further, as shown in FIG. 4D, when the part 30c is destroyed as a part to be destroyed, the upward parts 30a and 30b of the part 30c are both “completely destroyed”. That is, the part 30c is replaced with the destructive object 40, and the destructive process is performed on the replaced destructive object 40. Next, when the parts 30a and 30b fall together and the lower part 30b comes into contact with the ground surface GR, the part 30b becomes a part for total destruction and is replaced with the object for total destruction 60. The collapse process for 60 is performed. Subsequently, when the part 30a falls and reaches the ground surface GR, the part 30a is set as a part to be completely destroyed and replaced with the object for complete destruction 60, and the collapse process for the replaced object for complete destruction 60 is performed. As a result, none of the parts 30a to 30c remains.

  Further, when any part constituting the entire object is destroyed, the other parts 30 located adjacent to the part in the lateral direction are “collapsed” and “half-destructed”. FIG. 11 is a diagram for explaining “collapse” based on the positional relationship of “horizontal”, and shows an example of the composite object 20C. According to FIG. 5A, the composite object 20C is formed by integrating three parts 30a to 30c. That is, the parts 30a to 30c are arranged adjacent to one horizontal line. When any part 30 constituting the composite object 20C is “destroyed” as a destruction target part, the other parts 30 adjacent to the destruction target part in the lateral direction are “semi-destructed”.

  Specifically, as shown in FIG. 5B, when the part 30a is “destroyed” as a part to be destroyed, the part 30b adjacent to the part 30a in the lateral direction is “semi-destructed”. That is, the part 30a is replaced with the destructive object 40, and the part 30b is set as a semi-destruct target part and is replaced with the semi-destructive object 70, and the destructive process is performed on the replaced destructive object 40. At this time, since the part 30b is adjacent to the part 30a, which is the part to be destroyed, in the horizontal direction, the side part of the part 30 is partially broken, and the half broken part is adjacent to the part 30a. Replaced by orientation. As a result, the semi-destructive object 70 replaced with the part 30b and the part 30c remain.

  Further, as shown in FIG. 6C, when the part 30b is “destructed” as a part to be destroyed, the parts 30a and 30c located adjacent to each other in the lateral direction of the part 30b are “half-destructed”. That is, the part 30b is replaced with the destructive object 40, and each of the parts 30a and 30c is set as a semi-destructive target part and replaced with the semi-destructive object 70, and the destructive process is performed on the replaced destructive object 40. At this time, since the parts 30a and 30c are adjacent to the part 30b which is the part to be destroyed in the lateral direction, the side part of the part 30 is partially destroyed, and the half-broken part Is replaced in the direction adjacent to the part 30b. As a result, the semi-destructive object 70 arranged in place of the part 30 and the semi-destructive object 70 arranged in place of the part 30c remain.

  Also, as shown in FIG. 4D, when the part 30c is “destructed” as a part to be destroyed, the part 30b located adjacent to the part 30c in the lateral direction is “semi-destructed”. That is, the part 30c is replaced with the destructive object 40, and the part 30b is set as a semi-destruct target part and is replaced with the semi-destructive object 70, and the destructive process is performed on the replaced destructive object 40. At this time, since the part 30b is adjacent to the part 30c, which is the part to be destroyed, in the lateral direction, the side part 30 of the part 30 is partially broken, and the half-broken part 70c is adjacent to the part 30c. Is replaced by As a result, the part 30a and the semi-destructive object 70 arranged to replace the part 30b remain.

  Further, when the part to be completely destroyed constituting the composite object is “completely destroyed”, other parts located adjacent to the part to be completely destroyed are “collapsed” and “half-destructed”. FIG. 12 is a diagram for explaining the chained “half destruction” associated with “total destruction”. According to FIG. 6A, the composite object 20D is configured by integrating twelve parts 30a to 30l. That is, the parts 30j, 30k, and 30l are adjacent to each other in a horizontal line, the parts 30g, 30d, and 30a are arranged above the part 30j, and the parts 30h, 30e, and 30b are arranged above the part 30k, Parts 30i, 30f, and 30c are arranged above the part 30l.

  As shown in FIG. 5B, when the part 30d is “destructed” as a part to be destroyed, the upper part 30a of the part 30d is “collapsed” and “completely destroyed”, and the downward direction Each of the adjacent part 30g and the part 30e adjacent in the lateral direction and the part 30b adjacent in the lateral direction of the part 30a that has been “completely destroyed” are “semi-destructed”.

  That is, the part 30d is replaced with the destructive object 40, and the parts 30e and 30g are set as the parts to be partially destroyed and replaced with the semi-destructive object 70, and the destruction process for the replaced destructive object 40 is performed. At this time, since the part 30e is adjacent to the part 30d that is the part to be destroyed in the lateral direction, the side 30 of the part 30 is replaced with a horizontal half-breaking object 72, and the part 30g is replaced with the part 30d. Since the upper part of the part 30 is adjacent to the upper part, the upper part of the part 30 is replaced with the upper half-destroying object 71 that is partially broken.

  Next, when the part 30a falls and comes into contact with the upper surface of the half-destroy object 70, the part 30a is made a part to be completely destroyed and replaced with the object for total destruction 60, and is located adjacent to the lateral direction of the part 30a. The part 30b is set as a part to be partially destroyed and replaced with the object for half destruction 70, and the collapse processing for the whole object for destruction 60 is performed. At this time, since the part 30b is adjacent to the part 30 in the horizontal direction, the part 30b is replaced with the horizontal half-breaking object 72. As a result, the parts 30c, 30f, 30h to 30l, the horizontal half-disruption object 72 replaced with the parts 30b and 30e, and the upper half-disruption object 71 replaced with the part 30g remain.

  Furthermore, in the present embodiment, when the ground object is destroyed, predetermined effect processing (hereinafter simply referred to as “effect”) that emphasizes the destruction is performed. Specifically, an effect corresponding to each “destruction” or “collapse” of each part constituting the composite object is performed. That is, the “destructive effect” is performed when the part is “destructed”, and the “destructive effect” is performed when the part is “destructed”.

  FIG. 13 is a diagram illustrating an example of the destruction effect. FIG. 14 is a diagram showing an example of the appearance timing of each effect pattern constituting the destruction effect. According to FIGS. 13 and 14, at the time of destruction, three kinds of effects “flash effect”, “smoke effect”, and “particle effect” appear as destruction effects.

  Specifically, first, a flash effect appears. This flash effect is an effect that represents the flash of an explosion caused by a collision of a moving object, and the flash object LO appears for a short time (for example, 1 second) near the collision position of the moving object of the part to be destroyed, for example. To do.

  Then the smoke effect appears. This smoke effect is an effect that expresses smoke such as debris and dust due to the destruction of parts, and a large number of smoke objects SO made of opaque objects appear so as to cover the parts to be destroyed and parts to be partially destroyed. Each smoke object SO moves slowly so as to represent smoke flowing in the wind. In addition, with the appearance of the smoke effect (or a little later), the particle effect appears. This particle effect is an object representing particles representing debris and the like that are scattered by destruction and sparks generated, and a large number of particle objects PO appear to scatter from the smoke effect. Each smoke object SO and particle object PO gradually disappears as it gradually becomes transparent with the passage of time, and disappears completely when a predetermined time elapses from the appearance. Note that these objects do not affect the movement of parts, debris, and the like.

  The collapse effect is performed in substantially the same manner as the destroy effect. That is, only the point that two types of “smoke effect” and “particle effect” appear as the collapse effect is different from the destroy effect, and the other control is the same as the destroy effect.

  FIG. 15 is a diagram illustrating an example of the appearance timing of each effect pattern constituting the collapse effect. According to the figure, the smoke effect first appears at the time of collapse. In this smoke effect, a large number of smoke objects SO, which are opaque objects, appear so as to cover the parts to be collapsed or the parts to be partially destroyed. In addition, with the appearance of the smoke effect (or a little later), the particle effect appears. This particle effect appears so that each of a large number of particle objects PO scatters from the smoke effect. Each smoke object SO and particle object PO gradually disappears as it gradually becomes transparent with the passage of time, and disappears completely when a predetermined time elapses from the appearance. These objects do not affect the movement of parts, fragments, and the like by the destruction control unit 215.

[Function configuration]
FIG. 16 is a block diagram showing a functional configuration of the game apparatus 1000. According to the figure, the game apparatus 1000 functionally includes an operation input unit 110, a processing unit 200, an image display unit 330, a sound output unit 350, a communication unit 370, and a storage unit 400. Configured.

  The operation input unit 110 receives an operation input by the player and outputs an operation signal corresponding to the operation to the processing unit 200. This function is realized by, for example, a button switch, lever, dial, mouse, keyboard, touch panel, various sensors, and the like. In FIG. 1, the game controller 1120 corresponds to this.

  The processing unit 200 performs various arithmetic processes such as overall control of the game apparatus 1000, game progress, and image generation. This function is realized by, for example, a processor such as a CPU (CISC type, RISC type) or DSP, an arithmetic device such as an ASIC (gate array or the like), or a control program thereof. In FIG. 1, the CPU mounted on the control unit 1111 corresponds to this. In addition, the processing unit 200 mainly includes a game calculation unit 210 that performs calculation processing related to game execution, an image generation unit 230 that generates a game image based on various data obtained by processing of the game calculation unit 210, And a sound generation unit 250 that generates game sounds such as sound effects and BGM.

  The game calculation unit 210 executes various game processes based on operation signals input from the operation input unit 110, programs and data read from the storage unit 400, and the like. In the present embodiment, the game calculation unit 210 includes a moving body control unit 211, a collision determination unit 213, and a destruction control unit 215, and executes a battle game according to the game program 410.

  The moving body control unit 211 controls a moving body such as a missile fired from a fighter aircraft or a tank. The collision determination unit 213 determines the collision between the moving object controlled by the moving object control unit 211 and the ground object, and determines the collision position of the ground object with which the moving object collides.

  The destruction control unit 215 performs a process of destroying the ground object determined by the collision determination unit 213 that the mobile object has collided. Specifically, first, the parts to be destroyed are specified. That is, with reference to the ground object data 421 of the ground object determined to have collided with the moving body, the moving body among the parts constituting the ground object from the collision position of the moving body determined by the collision determination unit 213 The part that collided with is identified, and the identified part is the part to be destroyed.

  FIG. 17 is a diagram illustrating an example of the data configuration of the ground object data 421. According to the figure, the ground object data 421 is generated for each ground object arranged in the game space, and the object ID 421a, model data 421b, parts configuration data 421c, and parts data 422 of the ground object are obtained. Storing.

  The part data 422 is generated for each part constituting the ground object, and the part ID 422a, the mass 422b, the position / posture 422c, the moving speed 422d, the replacement flag 422e, the replacement object ID 422f, and the adjacent position of the part. Relation data 422g and replacement object data 422k are stored. The replacement flag 422e is a flag indicating whether or not the part has been replaced with a replacement object. The replacement object is an object to be replaced with each part, that is, a destruction object 40, a complete destruction object 60, or a semi-destruction object 70. The replacement object ID 422f stores the ID of the replaced object when the part is replaced with a replacement object.

  The adjacent positional relationship data 422g is data of other parts adjacent to the part, and includes an upper part 422h adjacent in the upward direction, a lower part 422i adjacent in the downward direction, and a lateral part 422j adjacent in the lateral direction. Each part ID is stored. The replacement object data 422k is data for determining a replacement object to be replaced with the part, and stores an object ID 422m in association with each replacement object type 422l. The part is replaced with any object defined by the replacement object data 422k, and the object ID of the replaced object is stored in the replacement object ID 422f.

  Here, the replacement object data 422k may be determined according to the material of the ground object. Specifically, for example, a material such as brick, concrete, or iron is determined as a main material for forming the ground object. Then, an object composed of the fragments 50 of the same material as the ground object is set as a replacement object in the replacement object data 422k as a replacement object. As a result, a more natural destruction is realized in which the material of the part 30 destroyed or collapsed and the debris scattered by the destruction or destruction match.

  Alternatively, the replacement object data 422k may be determined according to the fragility of the ground object. Specifically, the fragility is determined based on the formation state (for example, material, assembling method, etc.) of the ground object, and an object composed of fragments 50 having a size corresponding to the fragility is set as a replacement object. The replacement object data 422k is set.

  Of the replacement objects, the data of the destruction object 40 is stored in the destruction object data 423. Further, the data for the half-destroying object 70 is stored in the object data 424 for half-destruction, and the data for the object 60 for total destruction is stored in the object data 425 for total destruction.

  FIG. 18 is a diagram illustrating an example of a data configuration of the destructive object data 423. According to the figure, the destructive object data 423 is generated for each destructive object 40 determined to be replaced with each part 30 of the ground object, and the object ID 423a of the destructive object 40, model data 423b, Configuration piece data 423c is stored. The constituent piece data 423c stores a piece ID 423d, a mass 423e, and a relative position / posture 423f in association with each piece 50 constituting the destruction object 40.

  FIG. 19 is a diagram illustrating an example of a data configuration of the object data 424 for half destruction. According to the figure, the half-destructing object data 424 includes the upper half-destroying object data 424-1 of the upper half-destroying object 71 and the horizontal half-destroying object data 424-2 of the horizontal half-destroying object 72. The upper half-destroying object data 424-1 is generated for each upper half-destroying object 71 determined to be replaced with each part 30 of the ground object. The object ID 424a of the upper half-destroying object 71, the model data 424b, the mass 424c is stored. Further, the horizontal half-broken object data 424-2 is generated for each horizontal half-broken object 72 and is not shown, but has the same configuration as the upper half-broken object data 424-1.

  FIG. 20 is a diagram illustrating an example of the data configuration of the object data 425 for total destruction. According to the figure, the total destruction object data 425 is generated for each total destruction object 60 determined to be replaced with each part of the ground object, and the object ID 425a of the total destruction object 60, the model data 425b, and the configuration Fragment data 425c is stored. The configuration fragment data 425c stores a fragment ID 425d, a mass 425e, and a relative position / posture 425f in association with each fragment 50 constituting the total destruction object 60.

  When the destruction target part is specified, the destruction control unit 215 performs a process of “destructing” the destruction target part. That is, based on the adjacent positional relationship between the part to be destroyed and each of the other parts 30, the part to be completely destroyed and the part to be partially destroyed are specified. That is, with reference to the part data 422 of the destruction target part, the upper part defined by the adjacent positional relationship data 422g is set as a complete destruction target part, and each of the lower part and the lateral part is set as a semi-destruction target part.

  The data of each identified part is stored in the replacement target part data 426. FIG. 21 is a diagram illustrating an example of the data configuration of the replacement target part data 426. As illustrated in FIG. According to the figure, the replacement target part data 426 stores the respective part IDs of the destruction target part 426a, the complete destruction target part 426b, and the semi-destruction target part 426c.

  Subsequently, the destruction control unit 215 replaces the identified destruction target part with the destruction object 40 and replaces the half destruction target part with the half destruction object 70. That is, with respect to the part to be destroyed, the part data 422 of the part to be destroyed is referred to and replaced with the object for destruction 40 determined by the replacement object data 422k. Referring to FIG. 4, the object is replaced with the half-destructive object 70 determined by the replacement object data 422k. At this time, the half-destroy target part is replaced with a half-destroy object 70 having a shape in which a part adjacent to the target part is partially destroyed. That is, if the part to be destroyed is a horizontal part of the part to be destroyed, it is replaced with the object for horizontal half destruction 72, and if it is a lower part, it is replaced with the object for upper half destruction.

  The data of the destruction object 40 that is replaced with the destruction target part and placed in the game space is stored in the destruction replacement data 427, and the data of the half destruction object 70 that is replaced with the half destruction target part and placed in the game space is Stored in the replacement data 428 for half destruction.

  FIG. 22 is a diagram illustrating an example of a data configuration of the replacement data for destruction 427. According to the drawing, the destruction replacement data 427 stores a part ID 427a of the destruction target part, an object ID 427b of the destruction object 40 replaced with the destruction target part, and an action field ID 427c. For each piece 50 constituting the destruction object 40, a piece ID 427d, a position / posture 427e, a moving speed 427f, and a moving force 427g are stored in association with each other. The applied force field ID 427 c stores the force field ID of the breaking force field 80 that acts on the breaking object 40. The moving force 427g stores the moving force Fa applied to each piece 50 by the breaking force field 80.

  The data of the destructive force field 80 is stored in the destructive force field data 433. FIG. 23 is a diagram illustrating an example of a data configuration of the destructive force field data 433. According to the figure, the destructive force field data 433 includes force field ID 433a, applied force field pattern ID 433b, position 433c, size 433d, moving force 433e, and elapsed time of the set destructive force field 80. 433f is stored. The applied force field pattern ID 433b stores a pattern ID of a force field pattern applied to the breaking force field 80. The position 433 c stores the center position O of the breaking force field 80. The size 433d stores the radius R of the breaking force field 80. The elapsed time 433f stores the elapsed time from the generation of the destructive force field 80.

  The force field pattern is data for controlling changes in the force field (that is, the breaking force field 80 and the collapsing force field 90), and is data defining characteristics according to the type of the force field. The force field pattern data is stored in force field pattern data 435. FIG. 24 shows an example of the data structure of the force field pattern data 435. According to the figure, force field pattern data 435 is generated for each force field pattern, and stores the force field pattern pattern ID 435a, life 435b, size setting data 435c, and moving force setting data 435d. ing. The lifetime 435b is the time from the generation of the force field to the disappearance. The magnitude setting data 435c is data defining the magnitude (radius R) with respect to the elapsed time t from the generation of the force field. The moving force setting data 435d is data defining the moving force F with respect to the elapsed time t from the generation of the force field.

  FIG. 25 is a diagram illustrating an example of the data configuration of the replacement data 428 for half destruction. According to the drawing, the replacement data 428 for half destruction is generated every time the part to be partially destroyed is replaced with the object for half destruction 70, and the part ID 428a of the part to be partially destroyed, the object ID 428b of the object for half destruction 70, the position / posture 428c and moving speed 428d are stored.

  Subsequently, the destruction control unit 215 sets a destruction force field 80. That is, a force field pattern to be applied to the destructive force field 80 generated with reference to the destructive force field selection table 431 is selected, and the destructive force field 80 to which the selected force field pattern is applied is generated. Then, the center position of the destruction target part is set as the destruction center position, and the center position O of the generated destruction force field 80 is set to coincide with the destruction center position.

  FIG. 26 is a diagram illustrating an example of a data configuration of the destructive force field selection table 431. As illustrated in FIG. According to the figure, the destructive force field selection table 431 corresponds to a ground object type 431a arranged in the game space, a mobile object type 431b that may collide with the ground object, and a force field pattern ID 431c. It is attached and stored.

  The destruction control unit 215 applies the force field pattern of the force field pattern ID corresponding to the combination of the type of the ground object to be destroyed and the type of the moving body colliding with the ground object to the generated force field 80 for destruction.

  Thereafter, the destructive control unit 215 moves the debris 50 located in the destructive force field 80 out of the debris 50 constituting the destructive object 40 by the destructive force field 80 at a predetermined processing unit time interval. It identifies as the fragment 50 to which Fa is given, and the moving force Fa based on the force field 80 for destruction is added and set to each identified fragment 50 in an integrated manner. Then, based on the set moving force Fa, mass M, gravity, and the like, the moving direction, moving speed V, and the like are updated, and the fragments 50 and other parts 30 constituting the destructive object 40 are moved. The moving force Fa applied by the breaking force field 80 is added to the current movement of the shards 50 in an additional and cumulative manner. Therefore, as the time in the breaking force field 80 is longer, the speed of the fragments 50 increases at an accelerated rate, and the direction is a direction that radiates radially from the center of the breaking force field 80.

  The destruction control unit 215 controls the generated destruction force field 80 according to the applied force field pattern. That is, with reference to the force field pattern data 435 of the force field pattern, a process for resetting the magnitude (radius R) and the moving force Fa according to the elapsed time t since the generation of the breaking force field 80 is set to a predetermined value. Execute repeatedly at unit time intervals. When the elapsed time from the occurrence reaches the lifetime, the destructive force field 80 is extinguished. Therefore, after the destructive force field 80 disappears, no new movement force is applied to the debris 50. Therefore, all the debris 50 preserves the momentum when the destructive force field 80 disappears, and the mechanical energy It is controlled so as to take a free fall motion by a physical simulation calculation according to the law of conservation.

  In addition, when there is a complete destruction target part, the destruction control unit 215 performs a process of “disintegrating” the complete destruction target part. That is, when the part to be completely destroyed falls and comes into contact with the upper surface of the object located below the part, the destruction control part 215 starts the part effect data 422 of the part to be completely destroyed after the effect control part 217 starts the destruction effect. Referring to FIG. 5, the part to be completely destroyed is replaced with the object for complete destruction determined by the replacement object data 422k. The replacement of the parts to be completely destroyed is not limited to after the start of the destruction effect, but may be performed before or simultaneously with the start of the destruction effect.

  Further, based on the adjacent positional relationship between the completely destroyed part and each other part 30, the completely destroyed part and the partially destroyed part are specified. That is, with reference to the part data 422 of the part to be completely destroyed, the upper part defined by the adjacent positional relationship data 422g is set as the next part to be completely destroyed and the side part is set as the part to be partially destroyed. Then, the specified half-breaking target part is replaced with the half-breaking object 70. That is, with reference to the part data 422 of the part to be partially destroyed, the part data 422 is replaced with the object for half destruction 70 determined by the replacement object data 422k. At this time, since the part to be partially destroyed is a lateral part of the part to be completely destroyed, the part to be partially destroyed of the object for horizontal half destruction 72 is arranged in a direction adjacent to the part to be partially destroyed.

  Here, the data of the complete destruction object 60 replaced with the complete destruction target part is stored in the complete destruction replacement data 429, and the data of the partial destruction object 70 replaced with the partial destruction target part is stored in the partial destruction replacement data 428.

  FIG. 27 is a diagram illustrating an example of the data configuration of the complete destruction replacement data 429. As illustrated in FIG. According to the figure, the total destruction replacement data 429 is generated every time the part to be destroyed is replaced with the object for whole destruction 60, and the part ID 429a of the part to be completely destroyed, the object ID 429b of the object for total destruction 60, and the acting force The field ID 429c is stored, and the fragment ID 429d, the position / posture 429e, the movement speed 429f, and the movement force 429g are stored in association with each other for each fragment 50 constituting the total destruction object 60. The applied force field ID 429 c stores the force field ID of the collapse force field 90 that acts on the total destruction object 60. The moving force 429g stores the moving force Fb applied to the fragments 50 by the collapsing force field 90.

  Data of the collapse force field 90 is stored in the collapse force field data 434. FIG. 28 is a diagram illustrating an example of a data configuration of the force field data 434 for collapse. According to the figure, the collapse force field data 434 is generated for each set collapse force field 90, the force field ID 434a of the collapse force field 90, the applied force field pattern ID 434b, the position 434c, and the size. 434d, moving force 434e, and elapsed time 434f are stored. The applied force field pattern ID 434b stores the pattern ID of the force field pattern applied to the force field 90 for collapse. The force field pattern data is stored in force field pattern data 435. The position 434 c stores the center position O of the collapse force field 90. The size 434d stores the radius R of the force field 90 for collapse. The elapsed time 434f stores the elapsed time from the generation of the collapse force field 90.

  Subsequently, the destruction control unit 215 sets the collapse force field 90. That is, a force field pattern applied to the collapse force field 90 to be generated is selected with reference to the collapse force field selection table 432, and the collapse force field 90 to which the selected force field pattern is applied is generated. Then, the center position of the contact surface of the part to be completely destroyed is set as the collapse center position, and the generated center position O of the collapse force field 90 is set to coincide with the collapse center position.

  FIG. 29 is a diagram illustrating an example of a data configuration of the collapse force field selection table 432. According to the figure, the collapsing force field selection table 432 corresponds to a ground object type 432a arranged in the game space, a mobile object type 432b that may collide with the ground object, and a force field pattern ID 432c. It is attached and stored.

  The destruction control unit 215 applies the force field pattern of the force field pattern ID corresponding to the combination of the type of the ground object to be destroyed and the type of the moving object that has collided with the ground object to the generated force field 80 for destruction.

  Thereafter, the destructive control unit 215 moves the debris 50 positioned in the destructive force field 90 among the destructive objects 50 constituting the total destructive object 60 at a predetermined processing unit time interval by the destructive force field 90 using the moving force Fb. Are specified as the pieces 50 to be given, and the moving force Fb given by the disintegration force field 90 is added and set to each specified piece 50 in an integrated manner. Then, the moving direction and moving speed V are updated based on the set moving force Fb, mass M, gravity, and the like, and the fragments 50 and other parts 30 constituting the object for total destruction are moved. Further, when there is a next part to be completely destroyed, similarly, a process of “disintegrating” the part to be completely destroyed is performed.

  The effect control unit 217 controls an effect that appears when the destruction control unit 215 destroys the ground object. Specifically, when the destruction control unit 215 performs “destruction” of the destruction target part, a process for causing the destruction effect to appear is performed. That is, the destruction effect selection table 441 is referred to, and the destruction effect to appear is selected.

  FIG. 30 is a diagram showing an example of the data structure of the destruction effect selection table 441. According to FIG. 30, the destruction effect selection table 441 includes the ground object type 441a arranged in the game space, and the ground object. The type 441b of the moving body that may collide with the blasting time and the destruction effect ID 441c are stored in association with each other.

  The effect control unit 217 selects the effect of the destruction effect ID corresponding to the combination of the type of the ground object destroyed by the destruction control unit 215 and the type of the moving object colliding with the ground object as an effect to appear. . Then, the effect is caused to appear according to the destruction effect data 443 of the selected destruction effect. At this time, for example, the center position of the part to be destroyed is set as the appearance position of the effect, and each effect appears on the basis of the appearance position. Further, before the destruction control unit 215 replaces the destruction target part with the destruction object 40, the appearance of the destruction effect starts.

  The destruction effect data is stored in the destruction effect data 443. FIG. 31 is a diagram showing an example of the data structure of the destruction effect data 443. As shown in FIG.

For each frame 451b up to the point in time, the particle ID 451c, the relative position 451d, the color 451e, and the transparency 451f of each particle object PO to appear are stored in association with each other. The relative position 451d is set so that the change differs for each particle pattern. The transparency 452f is set to gradually become transparent as the frame progresses. In addition, the number of frames from the appearance to the disappearance (that is, the appearance period of the particle object PO) is set to be different for each particle pattern, and the number and types of the particle objects PO to appear are set to be different.

[Process flow]
FIG. 40 is a flowchart for explaining the flow of the game processing in the present embodiment. This process is realized by the game calculation unit 210 executing the game program 410. According to the figure, the game calculation unit 210 controls the player character in accordance with the operation data from the operation input unit 110 (step A1), and performs game progression control such as control of other characters and the passage of game time ( Step A3). Moreover, the mobile body control part 211 controls a mobile body (step A5). Next, the collision determination unit 213 determines a collision between the moving object and each ground object arranged in the game space (step A7). If it is determined as a result of the collision (step A9: YES), a destruction process for the ground object determined to have collided is started (step A11). Thereafter, the game calculation unit 210 determines whether or not to end the game, and if not ended (step A13: NO), returns to step A1, and if the game ends (step A13: YES), the game processing. Exit. The processing from step A1 to A3 is repeatedly executed at predetermined unit time intervals (for example, every frame time).

  FIG. 41 is a flowchart for explaining the flow of destruction processing. According to the figure, the destruction control unit 215 refers to the ground object data 421 of the ground object for which the collision has been determined, and identifies the destruction target part among the parts 30 constituting the ground object (step B1). ). Next, referring to the part data 422 of the specified destruction target part, the part to be completely destroyed and the part to be partially destroyed are specified (step B3).

  Then, the effect control unit 217 starts the destruction effect (step B5). That is, the destruction effect selection table 441 is referred to, the destruction effect to appear is selected, and each of the flash effect, the smoke effect, and the particle effect is caused to appear according to the destruction effect data 443 of the selected destruction effect.

  Thereafter, the destruction control unit 215 refers to the part data 422 of the destruction target part and replaces the identified destruction target part with the destruction object 40 determined by the replacement object data 422k (step B7). If there is a half-broken target part (step B9: YES), each half-broken target part is referred to the part data 422 of the half-broken target part to be a half-broken object 70 defined by the replacement object data 422k. Replace (step B11). Next, a destructive force field 80 to which the force field pattern selected with reference to the destructive force field selection table 431 is applied is generated, and the center position O of the generated destructive force field 80 is determined as the destructive center position. It is set so as to coincide with the center position of the destruction target part (step B13).

  Subsequently, the destruction control unit 215 performs a loop A process at predetermined unit time intervals (for example, every frame time). In loop A, it is determined whether or not the destructive force field 80 exists. If there is present (step B15: YES), the destructive force field of the current size among the debris 50 constituting the destructive object 40 is determined. The debris 50 located in 80 is specified as the debris 50 to which the moving force Fa is given by the destructive force field 80 (step B17). And the moving force Fa by the present moving force Fb of the destructive force field 80 is further given to each specified fragment 50 (step B19).

  Further, it is determined whether or not the collapse force field 90 exists. If there is (Step B21: YES), the process of loop B is performed for each collapse force field 90. In the loop B, among the pieces 50 constituting the entire destruction object 60 on which the collapse force field 90 acts, the fragments 50 located in the collapse force field 90 having the current size are moved by the collapse force field 90. It identifies as the fragment 50 to which force Fb is given (step B23). Then, the current moving force Fb of the collapsing force field 90 is further given to each identified fragment 50 (step B25).

  Loop B is performed in this way. When the processing of the loop B for each of the collapse force fields 90 is performed, the destruction control unit 215 then applies the newly given moving forces Fa, Fb, and the like to each of the parts 30 and the fragments 50 constituting the ground object. Based on the mass M or the like, a new moving direction, moving speed V or the like is calculated and moved (step B27).

  Subsequently, the destruction control unit 215 determines whether or not there is a complete destruction target part. If there is (Step B29: YES), the destruction control unit 215 determines whether or not the complete destruction target part has fallen. As a result, if it is determined that it has fallen (step B31: YES), the part data 422 of the part to be completely destroyed is referred to and the part to be completely destroyed and the part to be partially destroyed are specified (step B33). Next, the effect control unit 217 starts the collapse effect (step B35). That is, referring to the collapse effect selection table 442, the collapse effect to appear is selected, and each of the smoke effect and the particle effect appears according to the collapse effect data 444 of the selected collapse effect.

  Thereafter, the destruction control unit 215 refers to the part data 422 of the total destruction target part and replaces it with the total destruction object 60 defined by the replacement object data 422k (step B37). If there is a half-broken target part (step B39: YES), each half-broken target part is referred to the part data 422 of the half-broken target part to be a half-broken object 70 defined by the replacement object data 422k. Replace (step B41). Next, a collapse force field 90 to which the force field pattern selected with reference to the collapse force field selection table 432 is applied is generated, and the center position O of the generated collapse force field 90 is determined as the collapse center position. It is set in accordance with the position of the lower surface of the part to be completely destroyed (step B43).

  Subsequently, the destruction control unit 215 determines whether or not all the parts 30 and the fragments 50 constituting the ground object are stationary, and if not (step B45: NO), the destruction force field 80 and Each of the collapse force fields 90 is reset (step B47). That is, for the destructive force field 80, the destructive force field data 433 is referred to, and it is determined whether or not the elapsed time from the occurrence has reached the life. If not reached, the force field pattern data 435 of the force field pattern applied to the destructive force field 80 is referred to and updated to the magnitude (radius R) and the moving force Fa according to the elapsed time. Similarly, for each of the collapsing force field 90, it is determined whether or not the elapsed time from occurrence has reached the lifetime by referring to the collapsing force field data 434 of the collapsing force field 90. The collapse force field 90 is extinguished, and if not reached, the magnitude (radius R) and moving force Fb corresponding to the elapsed time are updated. On the other hand, if all the parts 30 and the fragments 50 are stationary (step B45: YES), the process of the loop A is terminated. Loop A is performed in this way. When the above processing is performed, the destruction processing is finished.

[Action / Effect]
As described above, according to the present embodiment, when the moving object collides with the ground object, the parts 30 with which the moving object collides are specified and specified as the parts to be destroyed among the parts 30 constituting the ground object. The destruction target part is replaced with a destruction object 40 constituted by a plurality of pieces 50 assembled together. In addition, a destructive force field 80 is set, and each piece 50 of the destructive object 40 is controlled to move based on the moving force Fa given by the destructive force field 80. The breaking force field 80 is controlled so as to gradually increase as the time elapses and the moving force Fa decreases, and disappears when a predetermined time elapses from the generation. That is, by replacing the part to be destroyed with the object 40 for destruction, a force field 80 for destruction is generated and gradually expanded, and a moving force Fa based on the force Fa given by the force field 80 is given to each piece. A new expression of destruction, such as moving and scattering 50, is realized.

  In addition, the other parts adjacent in the downward direction and the lateral direction of the specified part to be destroyed are made the parts to be partially destroyed and replaced with the object for half destruction, and the other parts 30 adjacent in the upward direction are the objects to be completely destroyed. It is considered as a part. When the part to be completely destroyed falls, the part to be completely destroyed is replaced with an object 60 for the whole destruction composed of a plurality of pieces 50, and another part 30 adjacent in the upward direction of the part to be completely destroyed is included. The other parts 30 that are adjacent to each other in the horizontal direction are set as the parts to be partially destroyed and replaced with the objects for half destruction. Then, a collapse force field 90 is set, and each fragment 50 of the total destruction target part is controlled to move based on the moving force Fb given by the collapse force field 90. Like the destructive force field 80, the destructive force field 80 is controlled so that it gradually increases with time and the moving force Fb decreases, and disappears when a predetermined time elapses. That is, when the part to be destroyed is destroyed, another part 30 located above the part to be destroyed is dropped, and the effect of realistic and flashy destruction is realized such that the parts collapse in a chained manner and are completely destroyed.

  In addition, an effect at the time of destruction appears at the time of destruction, and an effect at the time of destruction appears at the time of destruction. Specifically, at the time of destruction, an effect at the time of destruction appears before the replacement of the part to be destroyed with the object 40 for destruction, and at the time of destruction, the effect at the time of destruction comes before the replacement of the part to be destroyed to the object 60 for complete destruction. Appear. As a result, it is possible to realize an effect that emphasizes destruction or collapse, and to visually hide a portion where an unnatural image may occur when each part is replaced with an object.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can of course be changed as appropriate without departing from the spirit of the present invention.

(A) Destructive force field 80 and collapsing force field 90
For example, in the above-described embodiment, the breaking force field 80 and the collapsing force field 90 are both sphere regions and expand so that the radius R gradually increases, but the shape is not limited thereto, and Instead of expanding uniformly in all directions, it may be expanded non-uniformly. For example, assuming that the region is a rectangular parallelepiped and expands only in the lateral direction (horizontal direction in the game space), it is possible to express the state where the fragments are scattered in the lateral direction. Such a force field may be used depending on the type of moving body such as a missile or a bomb.

  Further, in the above-described embodiment, the destructive force field 80 and the collapsing force field 90 are set according to the combination of the type of the ground object and the type of the moving object that has collided with the ground object. It may be set according to the environment around the ground object. Specifically, the force pattern applied to the set force field is varied according to the weather such as sunny weather, storm, and snow. Further, the ground object may be changed according to the situation such as whether the ground object is in a normal state on the ground or in a special state where it is submerged.

  Further, in the above-described embodiment, the destructive force field 80 and the destructive force field 90 are supposed to disappear when a predetermined time elapses from generation (that is, when a predetermined life is reached). It may be extinguished when it reaches a predetermined size (specifically, the radius R reaches a predetermined radius Re).

  Further, although the destructive force field 80 and the collapse force field 90 disappear when they reach the end of their lives, they may disappear when they gradually decrease (that is, the radius R gradually decreases).

  In the above-described embodiment, the center position of the destruction target part is determined as the destruction center position, and the center position O of the destruction force field 80 is set to coincide with the destruction center position. You may set to positions other than. Specifically, for example, the position where the moving body of the part to be destroyed collides is set as the destruction center position, and the center position O of the destruction force 80 is set to coincide with the destruction center position.

  Further, the collapse force field 90 to be set may be varied for every “collapse” of the entire destruction target parts that is repeatedly performed. Specifically, for example, the lifetime of the collapse force field 90 set for each collapse is extended. As a result, each time the collapse is repeated, the moving force given to each piece 50 increases in an integrated manner, and as a result, the scattering distance of the pieces 50 increases. Accordingly, an expression is realized in which the scale of destruction gradually increases each time chain destruction is repeated. Or you may decide to enlarge the moving force Fb which the force field 90 for collapse to set for every repetition of collapse. In this case as well, the moving force Fb applied to each piece 50 is increased each time the collapse is repeated, and the scattering distance is increased.

(B) Moving force application object In the above-described embodiment, each of the breaking force field 80 and the collapsing force field 90 is set as a region, and the moving forces Fa and Fb are given to the fragments 50 located in this region. Alternatively, an object (moving force applying object) representing the breaking force field 80 or the collapsing force field 90 may be arranged to apply a moving force to the debris 50 that has come into contact with the object. Specifically, as shown in FIG. 42, a spherical force field object 82 corresponding to the destructive force field 80 first appears at a center position of the destructive object 40 with a radius of 0 (zero). Then, the force field object 82 is expanded by gradually increasing the radius R, for example, and a moving force Fa is applied to the debris 50 in contact with the surface of the force field object 82.

  The force field object 82 is a model formed by polygons. Then, contact between the force field object 82 and each piece 50 is determined by hit check calculation similar to the conventional one. Of course, the shape of the force field object 82 is not limited to a sphere, but may be other shapes. The same applies to the collapse force field 90.

  The force field object 82 may be an invisible object formed by a transparent polygon, or may be a visible object. In the case of a visible object, for example, a spherical object imitating a bomb or a fireball appears as a moving force imparting object, thereby enabling further destruction. Furthermore, after a visible object appears as a moving object imparted object, the transparency may be gradually increased so that the object is finally invisible.

(C) Moving Force In the above-described embodiment, the moving forces Fa and Fb provided by the breaking force field 80 and the collapsing force field 90 are uniform in the force field, but may be non-uniform. Specifically, for example, the center position O of the force field is the largest, and the moving force F is set to gradually decrease as the distance from the center position O increases.

  In addition, the moving forces Fa and Fb applied to the debris 50 by the breaking force field 80 and the collapsing force field 90 are gradually decreased with time, but may be gradually increased or may be constant. It may be. Further, in the above-described embodiment, the breaking force field 80 and the breaking force field 90 give the moving forces Fa and Fb to the pieces 50, respectively, but this gives the acceleration α or the moving speed V. May be.

  Further, the direction of the moving force Fa, Fb that each of the breaking force field 80 and the breaking force field 90 gives to each piece 50 is a direction from the center position O of the force field toward the representative point Q of the piece. Other directions such as a direction according to the wind force or a random direction may be used.

(D) Effect As an effect, a light source may be set in the game space. Specifically, for example, in the effect at the time of destruction, a point light source is caused to appear at the center position of the part to be destroyed for a short time (for example, 1 second). At this time, the color, light emission time, intensity, and the like of the light source to appear may be varied according to the type of the ground object including the destruction target part and the type of the moving object that has collided. Further, the appearance of this light source is not limited to the center position of the destruction target part, but may be another position, for example, a position where the moving body collides. Further, the type of light source may be other than the point light source.

  Further, only the light source may be set as an effect. In this case, the light source is allowed to appear for a slightly longer time (for example, 5 seconds) so that the replacement part of the destruction target part with the destruction object 40 is visually blocked, and the intensity of the light source is applied. Therefore, it is desirable to set the strength to such an extent that the color and contour of the part to be destroyed cannot be visually recognized.

(E) Varying the Destruction Speed Further, it is possible to vary the speed of a series of processes (hereinafter referred to as “destruction speed”) in which the other parts 30 collapse in accordance with the destruction of the destruction target part. Specifically, for example, it is realized by changing the moving speed of each fragment 50 and each part 30 of the destruction object 40 and the total destruction object 60. That is, when the movement control of the fragments 50 and the parts 30 is performed, the movement speed calculated based on the movement forces Fa, Fb, the current movement speed V, etc. given by the breaking force field 80 or the breaking force field 90 is a predetermined coefficient. By multiplying, the breaking speed can be varied by changing the speed to be slightly faster or slower. Alternatively, this is realized by changing the timing of replacement of the part to be completely destroyed with the object for complete destruction 60. That is, in the above-described embodiment, at the timing when the fall (contact) of the total destruction target part is determined, the total destruction target part is replaced with the total destruction object 60. This is a predetermined time (for example, after the fall is determined) , About several frame time) or when the distance between the part to be destroyed and the upper surface of the object located below reaches a predetermined distance, the part to be destroyed is replaced with the object 60 for destruction. , Variable destruction speed. In addition, the change in the destruction speed is determined according to the type of the moving object colliding with the ground object (for example, a missile or a bomb) or the type of the ground object with which the moving object collided (for example, a building or a tower). Also good.

(F) Destruction target object In the above-described embodiment, the destruction target object is a ground object arranged on the ground. However, other than this, for example, a submarine moving in the water, a fighter flying in the air, It may be another object such as a tank moving on the ground.

(G) Applicable Game Device In the above-described embodiment, the case where the present invention is applied to a home game device has been described. However, the present invention can be similarly applied to other game devices such as an arcade game device and a portable game device. is there.

(H) Game to be applied In addition, although the case where the game is applied to a battle game has been described, it may be a game that includes an expression in which an object is destroyed by a collision of a moving object, such as a plane that was hit in an airplane game. Needless to say, the same applies.
