Description

  The present invention relates to a game program and a game apparatus in which a player object can move on a large object in a three-dimensional virtual space.

  In video games, there is a game in which a player character operated by a user moves on a stage in a three-dimensional virtual space (game space) and battles enemy characters in the space (see, for example, Patent Document 1). Generally, the stage imitates a plain, a forest, a cave, a building, and the like, and the player character can move on the stage. There are also stages that imitate moving objects such as huge ships. In the case of a ship stage, for example, there is a game in which the player character moves on the deck of the ship and attacks an enemy character near the water surface around the ship.

JP 2010-142479 A

  In the case of the above-mentioned stage that does not move, the coordinates of the stage do not change in the virtual space defined by the world coordinate system, and the change of the stage itself is poor. Therefore, there has been a demand for a game having an unprecedented stage. In addition, even in a game having a stage representing a huge ship, the movement of the stage is expressed by moving the background, so the stage cannot be moved in a complicated manner, for example, in a curved line, and the change is poor. It was.

  An object of the present invention is to provide a game program and a game apparatus that form a large-sized object rich in change in a virtual space and improve the game's taste.

  The game program provided by the first aspect of the present invention generates a virtual space generating means for generating a three-dimensional virtual space, a large object moving in the virtual space, and the large object of the large object. It functions as a large object control means for controlling movement. The large object control means stores at least a plurality of phases in which a movement path of the large object is defined, and moves the large object while switching the phases.

  The large object control means may store the phase divided into a plurality of subphases, and move the large object by sequentially referring to the plurality of subphases.

  Each phase further defines the order of deforming the moving large object, and the large object control means may deform the large object according to the phase.

  In this case, the large object control means may store the phase divided into a plurality of subphases, and move and deform the large object by sequentially referring to the plurality of subphases.

  The computer is further caused to function as communication control means for controlling communication with a game apparatus of another user who operates another player object in the virtual space, and the communication control means transmits information on the current phase to the other game apparatus. In addition, information on the current phase may be received from another game device. When the communication control means receives the phase information, the large object control means may synchronize the movement and deformation of the large object based on the received phase information.

  The large object control means may branch the movement path of at least one of the plurality of phases and select the movement path (branch) of the large object according to the progress of the game.

  The computer may be further made to function as a player object control unit that generates a player object that is active in a virtual space and controls its operation, and the large object may be an enemy object that fights the player object. Then, the large object control means may select a movement path of the large object according to the attack by the player object.

  A game device provided by a second aspect of the present invention includes a program storage unit that stores the game program, and a computer that executes the game program stored in the program storage unit.

  According to the present invention, it is possible to form a large object that is rich in change in the virtual space, and to cope with the movement of a complicated stage, and to improve the taste of the game.

Further, the processing procedures of the respective flowcharts are not limited to the embodiment and are in no particular order as long as no contradiction occurs.

  FIG. 1 is a block diagram showing the configuration of the game system 1 of this embodiment. The game system 1 includes a game device 2 and executes a predetermined video game (game). The game apparatus 2 reads and executes the game program 50 from the memory card (storage medium) 5 on which the game program is recorded, and executes the game, and causes the display unit 41 to display the generated game image.

  The game apparatus 2 according to the present embodiment provides a game in which a user's player character (player object) moves large objects A to C (see FIG. 2) and fights enemy characters (enemy objects) in a three-dimensional virtual space. To do. Details will be described later.

  The game apparatus 2 includes a control unit 20, an operation unit 30, a media interface 31, and a wireless communication circuit unit 32 on the bus 26. The control unit 20 includes a CPU 21, a ROM (flash memory) 22, a RAM 23, an image processor 24 and an audio processor 25. A video RAM (VRAM) 40 is connected to the image processor 24, and a display unit 41 is connected to the VRAM 40. The display unit 41 includes, for example, two liquid crystal displays. An amplifier 42 including a D / A converter is connected to the audio processor 25, and the speaker 16 and the earphone terminal 17 are connected to the amplifier 42.

  The wireless communication circuit unit 32 communicates with other game devices 1 and server devices by Wi-Fi, Bluetooth (registered trademark). By communicating with other game apparatuses 1 and exchanging user operation data and the like, multiplayer is performed in which the plurality of game apparatuses 1 respectively control a plurality of player characters.

  The operation unit 30 includes a controller composed of, for example, a button, a cross key, a slide pad, a touch panel, and the like. The operation unit 30 detects the operation of the controller by the user and inputs the operation signal to the CPU 21.

  A memory card 5 inserted in a slot (not shown) is connected to the media interface 31. The memory card 5 is a semiconductor medium and stores a game program 50. The game program 50 includes game data such as stage image data and item images necessary for the progress of the game, in addition to the program body.

  A work area that is used when the CPU 21 executes the game program 50 is set in the RAM 23. The work area includes various parameters generated as the game progresses. The ROM 22 stores a basic program for executing the game program 50.

  The image processor 24 includes a GPU (Graphics Processing Unit) that can generate a game video. The image processor 24 generates a game space in accordance with an instruction from the CPU 21, and draws an image obtained by photographing the game space with a virtual camera on the VRAM 40 as a game image.

  The sound processor 25 has a DSP (Digital Signal Processor) that generates game sound. The sound processor 25 outputs the generated game sound to the amplifier 42. The amplifier 42 amplifies this audio signal and outputs it to the speaker 16 and the earphone terminal 17.

  Next, a game provided by the game apparatus 2 by executing a game program will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a three-dimensional virtual space 60 in the game of the present embodiment.

  In the virtual space 60, an X-axis, Y-axis, and Z-axis world coordinate system (fixed coordinate system) with a fixed origin is set. Objects such as the player character PC and large objects A to C are generated (arranged) in the virtual space 60. The position of the object in the virtual space 60 is expressed in the world coordinate system. One point inside or around the object is a point representing the object (local origin), and the coordinates of this local origin (world coordinate system) are the position of this object. The orientation of the object is defined in a local coordinate system with the local origin as the origin. Since the local origin is attached to the object, when the object moves and the position in the world coordinate system changes, the local coordinate system moves accordingly. The player character PC is active in the virtual space 60 and changes its posture in response to a user operation. The large object A is active in the virtual space 60 and changes its posture as the game progresses.

  For objects including the player character PC and the large objects A to C, collision determination areas having substantially the same shape as the objects are set. The collision determination area is an exclusive space area that the object occupies in the virtual space 60. Since it is an exclusive area, the progress of the game is controlled so that a plurality of objects do not share the same area (world coordinates). Specifically, when a moving object tries to move, it is determined whether or not the same area as another object is not shared (contact determination processing, attrition processing). If it is determined that the moving object and the other object share the same area, the moving object is in the state immediately before sharing the same area as the other object, that is, in the state of contact. Stop.

  The collision determination area is defined by a polygon representing the surface shape. This polygon is called Atari. The collision determination area is also deformed in accordance with the change in the posture of the object. The deformation is performed by changing the vertex coordinates of the polygon.

The large objects A to C have a stage surface (ground) on which the player character PC can ride and act. The player character PC can move on the large objects A, B, and C, and can move between the large objects A to C.
The large objects B and C are fixed objects. In the large object B, the upper surface portion (shaded portion) is the stage surface B1, and the attribute of the ground surface (stage surface) is given to the polygon face corresponding to the upper surface portion. In the large object C, the upper surface portion (shaded portion) is formed as the stage surface C1, and the attribute of the ground surface (stage surface) is given to the polygon face corresponding to the upper surface portion. When contact between the player character PC and the stage surface B1 is determined to be contacted, the position of the player character PC is corrected such that the player character PC is positioned (grounded) on the upper surface of the stage surface B1. Thereby, it can be set as the state which player character PC does not enter under the stage surface B1, and is riding. That is, a state where the player character PC is standing (stopped) on the ground and a state where the player character PC is moving on the ground is expressed.

  Further, the side surface portion (halftone dot portion) B2 of the large object B is a surface on which the player character PC cannot ride, and a wall face attribute is given to the polygon face corresponding to the surface B2. A side surface portion (halftone dot portion) C2 of the large object C is a surface on which the player character PC cannot ride, and a wall face attribute is given to the polygon face corresponding to the surface C2. For example, when the play character PC touches the wall surface B2 of the large object B, the position of the player character PC is outside the wall surface B2 so that the player character PC does not enter the inside of the object B. To be corrected.

  The large object A is an object on which the player character PC can ride, but is an object that moves and changes its posture as a character as will be described later. Which range of the polygon can be ridden (whether it is a stage surface) is determined by attribute information including, for example, which surface is a stage surface and a wall surface.

  The large object A moves along the route M and the route M-1 or M-2 indicated by a broken line as time elapses. That is, the position of the large object A in the world coordinate system changes. The position of the large object A is represented by the position of the center of gravity of the large object A. In the present invention, the representative position is not limited to the gravity center position.

  The large object A also acts as an enemy character (enemy object) that is an attack target of the player character PC. That is, the large object A is set with various parameters as a character such as physical strength and is attacked by the player character PC. Then, when the damage is received by the attack, the physical strength value (current value) decreases. Hereinafter, the large object A may be referred to as an enemy character A. The player character PC can perform an attacking action on the enemy character A (large object A) while riding on the large object A. The player character PC can also perform an attacking action on the stage B and C. An attack operation can also be performed in A).

  As shown in FIGS. 3B and 4B, the enemy character A is a dragon object having a head, neck, torso, two front legs, two hind legs, and a tail. A quadruped walking (see FIG. 3) by the hind legs and a biped walking (see FIG. 4) by the hind legs are possible. The enemy character A has a volcano-shaped object V on its back.

  FIG. 3A is a plan view showing a schematic shape of the enemy character A during quadruped walking, and FIG. 3B is a side view showing a schematic shape of the enemy character A during quadruped walking. FIG. 4A is a plan view showing a schematic shape of the enemy character A during biped walking, and FIG. 4B is a side view showing a schematic shape of the enemy character A during biped walking. 3A and 4A are plan views for explaining the stage surfaces A1 to A13, and side views of FIGS. 3B and 4B for explaining the shapes. The details do not match.

  At the time of quadrupedal walking, as shown in FIG. 3A, in the large object A, seven stage surfaces A1 to A7 are formed according to the height difference. Each stage surface A1-A7 has a height difference mutually, and the boundary is a wall surface (atari). The player character PC can move back and forth between the stage surfaces A1 to A7 by performing an action of climbing a wall surface or an action of jumping.

  On the other hand, when walking on two legs, the large object A has six stage surfaces A8 to A13 as shown in FIG. These stage surfaces A8 to A11, A13 are locations that were wall surfaces during quadrupedal walking. Conversely, A1 to A6, which were stage surfaces during quadrupedal walking, are wall surfaces during bipedal walking. The stage surface A12 during biped walking is a part of the stage surface A7 during quadruped walking. In accordance with the change in the posture of the large object A (enemy character A), the shape and angle of the atari (polygon) change, and the stage surface on which the player character PC can ride also changes. Which surface of the atari is the stage surface and the wall surface during quadruped walking and biped walking may be stored in advance in a table, and is based on the shape and angle of the large object A at that time. It may be decided each time. In this embodiment, attribute information indicating which face of the atari is a stage face and a wall face is referred to during quadruped walking and biped walking, respectively. The attribute information is included in the game data.

  In a state where the player character PC is on any one of the stage surfaces A1 to A13 of the large object A, when the attribute of the riding stage surface is changed to a wall surface, the player character PC is placed directly below the stage surface. Fall to. Further, the player character PC also falls when the position of the player character PC deviates from the stage surface due to the change of the shape of the stage surface, such as the stage surface A12 to the stage surface A12.

  Here, the position control of the player character PC in the virtual space 60 will be described. As described above, the position of the player character PC is determined in the world coordinate system, that is, the position of the local origin, and the posture is controlled in the local coordinate system with the local origin as the origin.

  The position of the local origin of the player character PC changes depending on the action of the player character PC such as movement (walking and running), flying, falling). Further, the position of the local origin of the player character PC is corrected in accordance with the movement of the large object A and the change in posture when the player character A is on the stage surfaces A to A13.

  In the present embodiment, if the player character PC is on any of the stage surfaces A1 to A12, the player character PC falls from the stage surface even if the large object A moves (the position of the world coordinate system changes). Without moving, the large object A moves with the movement. For example, when the player character PC is stopped (upright) at a certain position on the stage surface A1, even if the large object A moves, the player character PC continues to stand at the same position on the stage surface A1. The state of riding on the stage surfaces A1 to A13 is a state in which it is determined that the attack of the player character PC is in contact with the attack of the stage surface.

  Further, even when the enemy character A changes its posture while the player character PC is on any of the stage surfaces A1 to A12, it does not fall off the stage surface and moves according to the change in the posture of the large object A To do. For example, when the stage surface on which the player character PC is riding rises due to a change in the posture of the enemy character A, the player character PC also moves up in synchronization with the rise of the stage surface.

  Next, a method for calculating the current local origin (X (n), Y (n), Z (n)) of the player character PC will be described. X (n) of the local origin is calculated using, for example, the following calculation formula (1). That is, it is calculated by adding the displacement when one frame has elapsed to the previous coordinate (n-1 frame) of the local origin. In this embodiment, in addition to the displacement based on the action of the player character PC, the displacement of the movement of the large object A and the displacement of the atari due to the change of posture are added. The action of the player character PC includes actions such as movement (walking and running), flying, and falling). The Y coordinate and Z coordinate of the local origin are the same calculation formula. The calculation formula for calculating the local origin is not limited to the following calculation formula (1).

X (n) = X (n−1) + ΔXa (n) + ΔXS (n) (1)
ΔXa: displacement from the previous frame based on the action of the player character PC (X axis)
ΔXS: Displacement (X axis) of the point where the player character PC of the large object A is on (contact point) from the previous frame
n: Current frame number (integer)
ΔXS (n) = ΔXSa (n) + ΔXSb (n)
ΔXSa: displacement from the previous frame based on the movement of the large object A (X axis)
ΔXSb: Atari displacement from the previous frame due to a change in posture of the large object A (X axis)

  Note that the sizes of the player character PC and the large object A are not limited to the ratio shown in FIG.

  In the present embodiment, the position of the world coordinate system (local origin) of another object (non-player object) riding on the large object A and the output position of the world coordinate system of the effect related to the large object A are As with the player character PC, the correction is made in accordance with the movement of the large object A and the change in posture.

  The effects are visual effects such as flame, smoke, sound (explosive sound), and acoustic effects (flame, smoke, sound). For example, when an attack by the player character PC hits the enemy character A, the output position is calculated based on the hit position. Further, for example, in the case of the enemy character A's trap, the output position of the sound is calculated based on the position of the head of the enemy character A. Since the effect output is a general configuration, a detailed description thereof will be omitted.

  When the effect occurs in relation to the large object A, the output position of the effect in the world coordinate system is corrected in the same manner as the player character A riding on the large object A. Note that the correction of the output position of the effect may be delayed from the movement of the large object A by gradually reducing the correction amount according to the elapsed time from the start of output. Alternatively, the correction of the output position may be ended when a predetermined time has elapsed from the start of output.

  Core objects W1 and W2 are arranged on the stage surfaces A2 and A5. The core objects W1, W2 are weak points of the enemy character A, and the player character PC can damage the enemy character A by attacking them.

  When walking biped, the core object W2 is hidden, and another core object W3 appears near the head of the enemy character A. This core object W3 is also a weak point of the enemy character A, and the player character PC can attack the enemy character A by attacking it. In addition to the core objects W <b> 1 to W <b> 3, the physical strength of the enemy character A can be reduced even when an attack is applied to the head or front foot of the enemy character A, for example. Further, only an attack on the core object may be validated as an attack on the enemy character A.

  Next, the operation of the enemy character (large object A) will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of the phase table 95. The enemy character A moves along the route M or the like as time passes, but the movement is managed in phases. In the present embodiment, there are roughly four phases F0 to F3. Each phase F0 to F3 is associated with a subphase. The sub-phase is associated with operation information (control information) and transition condition information. In the action information, the action content to be executed by the enemy character A is registered. As the transition condition, the transition condition to the next subphase (phase) is registered.

  The game apparatus 2 controls the action of the enemy character A with reference to the action information in order from the subphase F0-0 of the phase F0 at the start of the game. Finally, the game ends when the final sub-phase F3-3 or F3-4 transition condition of the phase F3 is satisfied.

  At the start of the game, the player character PC is controlled to start moving on the route set in the air of the virtual space 60 and to get down to the position P3 of the stage surface A7 of the enemy character A. After the landing, an operation for moving the player character PC by the user is accepted.

  In addition, as indicated by the motion information of subphase F0-0, the enemy character A performs a standby (stop) motion in a biped state at the position K1. When the position of the moving player character PC reaches the position P1, the sub-phase F0-0 is shifted to the sub-phase F0-1. Also in the subphase F0-1, the enemy character A continues to perform a standby (stop) operation in a bipedal walking state. Also in the sub-phase F0-2, the enemy character A continues the standby (stop) action in the bipedal walking state, but performs the habit action when the condition W1 is satisfied. The condition W1 is, for example, that the player character PC has reached a position P3 (such as a position approaching the enemy character A). Then, after the dredging, in subphase F0-3, the enemy character A performs a standby (stop) action in a quadruped walking state.

  When the transition condition for the sub-phase F0-3 is satisfied, the process proceeds to the sub-phase F1-0 of the next phase F1. The waiting enemy character A moves on the route M by quadrupedal walking toward the position K2 (not shown). Thereafter, in sub-phase F1-2, the enemy character A moves to a position K4 (not shown) by quadruped walking. However, when the condition W2 is satisfied, the enemy character A switches from quadruped walking to biped walking. Move to K4. The condition W2 is, for example, that the player character PC has successfully made a predetermined attack against the enemy character A. For example, when the biped walking posture is more likely to attack the enemy character A than the quadruped walking posture, or when it is difficult for the enemy character A to attack, the user (( The player character PC) can advantageously advance the game.

  In the present embodiment, the player character PC is maintained on the enemy character (large object) A in the phases F01 and F1, and cannot move to the large objects B and C. When the enemy character A moves and approaches the large objects B and C in phases F2 and F3, the player character PC may move from the enemy character A to the large objects B and C and attack the enemy character A. It becomes possible.

  Further, the player character PC can perform an attack other than an attack that reduces the physical strength of the enemy character A. For example, there is a binding attack that restricts the movement of the enemy character A. When the restraint attack is successful, the enemy character A cannot move or the travel speed decreases until a predetermined restraint time (for example, 30 seconds) elapses. Therefore, the attackable time for the enemy character A is extended.

  Further, in sub-phase F3-2 of phase F3, the enemy character A performs a destructive attack of the large object C at the attack position AT close to the large object C. The player character PC attacks the enemy character A by transferring from the enemy character A to the large object C. Then, when the durability set for the large object C decreases to a predetermined value due to the attack of the enemy character A, the process proceeds to subphase F3-4, where the enemy character A destroys the large object C and follows the route M-2. Move to end the game. In this case, the game of the user is not cleared. In subphase F3-2, if the physical strength of enemy character A decreases to a predetermined value before the durability of large object C decreases to a predetermined value, the process moves to subphase F3-3 and enemy character A moves to subphase F3-3. The route M-1 is moved and the game ends. That is, the large object C is not destroyed and the game is cleared.

Next, functions of the game apparatus 2 will be described with reference to FIG. FIG. 6 is a functional block diagram of the game apparatus 2 of this embodiment. The game device 2 functions as the game progress control unit 200, the communication control unit 250, and the like in cooperation with the game program 50.
The game progress control unit 200 controls the progress of the game based on an operation signal from the operation unit 41 or the like. The game progress control unit 200 includes a virtual space generation unit 210, a player character control unit 220, a large object control unit 230, and an effect control unit 240.

  The virtual space generation unit (virtual space generation means) 210 generates a three-dimensional virtual space 60. The player character control unit (player character control means) 220 generates a player character PC that is active in the virtual space 60 and controls its action (attack, movement, etc.). Further, the player character control unit 220 moves the large object A (local coordinate system) to the position (local origin) represented by the world coordinate system of the player character PC when riding on the large object A, and Correction is performed in synchronization with a change in the shape (posture) of the large object A defined in the coordinate system.

  The large object control unit (large object control means) 230 generates large objects A to C. The large object control unit 230 controls the movement and movement (posture) of the large object A based on the phases F0 to F3 and the like. The effect control unit (effect control means) 240 controls the output of the effect in the virtual space 60 based on the game progress. Further, in the case of an effect related to the large object A, the effect control unit 240 determines the output position of the effect in the world coordinate system, the large object defined by the movement of the large object A (local coordinate system) and the local coordinate system. Correction is performed in synchronization with a change in the shape (posture) of the object A.

  The communication control unit (communication control means) 250 controls communication with the game device 2 of another user who operates another player character PC in the virtual space 60. For example, in the above-described virtual space 60, when a game is played in cooperation with another user's player character PC, communication with the other user's game device 2 is performed in a peer-to-peer manner, and data necessary for the progress of the game is mutually transmitted. To do. In this case, one game device 2 may control the game progress as a host. The host game device 2 receives user operation information and the like from each game device 2, performs a game progress process, and transmits the result to each game device 2. In addition, the host game device 2 (communication control unit 250) also transmits information on the current phase and subphase of the enemy object A to the other game devices 2. Thereby, the action of the enemy character A can be synchronized with each game device 2. Even if communication with the host game device 2 is interrupted, one of the remaining game devices 2 becomes the host, and the action of the enemy character A is continuously controlled based on the phase and subphase. can do.

  Next, the progress process of the game in the virtual space 60 shown in FIG. 2 will be described with reference to the flowchart of FIG. FIG. 7 is a flowchart showing the game progress process of the present embodiment. The game progress process shown in FIG. 7 is mainly executed by the game progress control unit 200. In FIG. 7, processing related to the player character PC and the enemy character A will be mainly described, and other processing will be omitted.

  First, the game progress control unit 200 generates a virtual space 60 as shown in FIG. 2 (step S10) and performs initial setting (step S11). In the initial setting, for example, the current phase of the enemy object A: F0, the subphase: F0-0, and the posture information of the enemy object A: biped walking are set.

  Next, the game progress control unit 200 executes an update process for the player character PC (step S12). For example, an attrition process between an atari of the player character PC and an atari of another object is performed. Further, the movement of the player character PC is controlled (updated) based on operation information from the operation unit 41, collision determination, and the like. When the player character PC is on the enemy object A, the position of the player character PC in the world coordinate system is corrected as described above.

  Thereafter, the game progress control unit 200 performs an update process for the enemy object A (step S13). For example, the movement of the enemy object A is controlled based on the current phase and subphase. Further, the physical strength is updated by the attack of the player character PC. Then, the game progress control unit 200 updates the current phase and subphase of the enemy character A and the posture information of the enemy character A based on the result of the update process of step S13 (step S14). The posture information of the enemy character A is used when referring to the attribute information of the enemy character A atari.

  Next, the game progress control unit 200 performs effect processing (step S15). For example, the effect to be generated is determined based on the results of the update processing in steps S12 and S13, and the output position is calculated. When the effect is related to the enemy object A, the position of the effect output position in the world coordinate system is corrected as described above.

  Thereafter, the game progress control unit 200 determines whether the game is over (step S16). For example, when the sub-phase F3-3 or F3-4 of the enemy character A is finished (transition condition is established), it is determined that the game is finished. If the game has not ended (NO in step S16), game progress control unit 200 returns to the process in step S12. On the other hand, when the game is over (YES in step S16), the game progress process is finished.

  As described above, the position of the world coordinate system of the player character PC riding on the large object A is corrected in accordance with the movement of the large object A (local coordinate system). That is, the large object A with the player character PC changes. Thereby, the large-sized object A rich in change can be formed in the virtual space 60, and the taste of the game can be improved. Also, since the shape of the large object A itself changes, the large object A changes more, and the game's preference is further improved.

  In the present embodiment, the large object A is an enemy character, but the large object may not be an enemy character. For example, it may be a teammate character as long as it is a large object having a stage surface on which at least the player character PC can ride. Further, the large object A may be configured such that only one of movement and shape change is performed.

  In the above-described embodiment, the behavior of the large object A is controlled based on the phase, but is not particularly limited thereto. Any control method may be applied.

  The game of the above-described embodiment may be applied to any genre as long as it is configured to include a large object having a stage surface on which a player character can ride.

  The shape and the like of the large object A may be switched between when it is not moving and when it is moving like the other large objects B and C. Other enemy characters may ride when they are not moving.

  In the game system of the above-described embodiment, the game machine is executing a game alone, but is not limited to this. For example, an online game system in which a game machine is connected to a game server device via the Internet or the like may be used. In this case, the operation processing described with reference to FIG. 7 may be executed in the game server device. Alternatively, the game server device and the game machine may execute the operation process jointly.

  The present invention is useful for forming a large-sized object that is rich in change in a virtual space and improving the taste of the game.
