Description

  The present invention relates to a program, an information storage medium, and an image generation system.

  2. Description of the Related Art Conventionally, an image generation system that generates an image that can be seen from a given viewpoint in an object space that is a virtual three-dimensional space is known, and is popular as being able to experience so-called virtual reality.

  In such an image generation system, it is an important technical problem to generate a more realistic image in order to improve the player's virtual reality.

  In conventional games, for example, a game in which a moving object (for example, a character) moves in space (non-attractive space) and a game in which a moving object (for example, a character) moves on the ground surface are known.

  For example, if only the former is used, the character in the outer space (non-attractive space) can control the movement motion by performing the movement control by the external force generated by the player input or other game factors without applying the attractive force. it can.

If only the latter is used, the character can control the movement motion in outer space (non-attractive space) by applying the attractive force and performing the movement control by the external force generated by the player's input or other game factors. .
Japanese Patent No. 3467487

  However, in a game space such as outer space where there is a character and a space ship on which the character can land, and in a game in which the character can be moved in and out of space by an operation input by a player, the character is in outer space. It is natural to control the character with a movement action in the non-attractive state when it is floating on the surface, and to move the character on the spacecraft as if it were on the spacecraft when the character is landing on the spacecraft. Give a feeling.

  When realizing such a game, it is conceivable to set a virtual attractive force on the spacecraft as on the ground. For example, when the terrain is wide and flat, it may be configured to generate a downward attractive force (for example, the y-axis direction), or when uneven terrain is important, the vertical direction of each surface of the object A configuration in which the attractive force is set to the above may be used.

  However, in the former, it is not possible to perform control such that the character moves around the spaceship. In the latter case, if the gravitational force is set in the direction perpendicular to each surface of the spacecraft object, the gravitational direction changes greatly depending on the shape of the spacecraft, resulting in a large character posture, first-person viewpoint background image, etc. It will change, making it difficult to see and unnatural.

  The present invention has been made in view of such a conventional problem, and an image generation system capable of performing attractive force control that is natural and comfortable for a moving object that is in a landing state with respect to the object, and An object is to provide an information storage medium.

(1) The present invention
In the game space, a movable object and a movable object are landed and a landable object that can move is arranged, and the movable object is configured to be able to move between a non-landing state and a landing state relative to the landable object, A program for generating an image of a game in which a moving object is moved by performing different attractive force control on the moving object in a non-landing state and a landing state,
A landing object information storage unit that stores attraction information that the landing object acts on a moving object;
When the mobile object is in a landing state on the landing object, the attractive action direction parameter to be applied to the mobile object in each frame is determined based on the attractive information that the landing object applies to the mobile object; A movement / motion calculation unit that calculates at least one of the movement and movement of the moving object by applying an attractive force to the moving object based on the attractive force direction parameter;
The computer functions as an image generation unit that generates an image of the game space viewed from a virtual camera,
The landing object information storage unit
Storing an attractive force direction to be applied to a moving object in association with a surface constituting an attractive force setting object set corresponding to the landing possible object;
The movement / motion calculation unit is
The hit of the moving object and the attractive force setting object is detected, the direction difference between the attractive force acting direction parameter and the attractive direction set on the hit surface is detected, and if there is a direction difference, the hit surface is set. Using the gravitational force direction as a correction target value, a correction amount per frame is determined so as to gradually approach the correction target value over a predetermined time, and the attractive force direction parameter is corrected with the determined correction amount. Thus, a process of correcting the direction of attractive force applied to the moving object is performed.

  The present invention also relates to a computer-readable information storage medium that stores (records) a program that causes a computer to function as each unit. The present invention also relates to an image generation system including the above-described units.

  The game space is, for example, outer space or the sea, the moving object is an object that is controlled to move by an external input, such as a character object, and the landingable object is, for example, a planet, a spaceship, or a meteorite. A moving object such as a ship is an object that can land on the ground and move on the surface.

  The attractive force is a force acting between two objects, and here, attention is focused on a portion where a landable object acts on a moving object. In this game, for example, a force such as gravity acting on an object on the earth (this force is referred to as an attractive force) is applied to the moving object in the landing state, and motion control is performed as if the attractive force is acting. Therefore, the gravitational force in the present invention may be gravity or pseudo-gravity, or may be other force that maintains the landing state (for example, force in the case where the mobile object such as a thruster (thrust) generates its own force).

  Here, the attractive direction is a direction component of an attractive vector (magnitude and direction of attractive force) that acts on a moving object (for example, a character object).

  The attractive force setting object may be set based on the shape of the landing object. For example, it may be shared with a polygon model (for example, a terrain model) for generating an image of a landable object, or may be shared with a polygon model set for hit check. A polygon model may be set for setting the attractive force. In this case, a polygon model in which the shape of the landable object is simplified may be set.

  The direction of the attractive direction set for each surface (for example, a polygon surface) can be set to be opposite to the normal vector of the polygon surface.

  The attractive force direction parameter holds the direction of the attractive force applied to the landing object in each frame, and the attractive force is applied to the moving object in the landing state for each frame based on the attractive force direction parameter. can do. Note that the attractive force direction parameter may be set, for example, as the initial value of the attractive force direction set on the first hit surface.

  The direction difference between the attractive force direction parameter and the attractive direction set on the hit surface may be, for example, an angular difference between directions.

  In the landing state, the moving object is subjected to the action of the attraction of the landable object, and the moving object in the landing state has a movement vector (speed, acceleration, or force vector) set by input information from the player, The moving position is determined based on the attractive direction (acceleration or force vector corresponding to the attractive force), and the object moves on the landable object.

  The landing state is a state where the moving object and the landing object are hit. A hit between a moving object and a landable object is detected every frame as the moving object moves, for example. If the hit between the mobile object and the landable object is not within a predetermined period (during a predetermined frame), it may be determined that the mobile object has transitioned from a landing state to a non-landing state (for example, a floating state). Good.

  In the present invention, when a mobile object hits a landable object, even if the attractive force direction set on the hit surface is different from the attractive force direction parameter (the attractive force direction currently applied to the mobile object), Or (in one frame), the attractive force direction parameter (the attractive force direction currently applied to the moving object) is not corrected to the attractive force direction set on the hit surface, but is set to the polygon of the hit surface. Using the attractive direction as a correction target value, a process for correcting an attractive force direction parameter that is applied to the moving object so as to gradually approach the correction target value over a predetermined time is performed.

  For this reason, it takes a predetermined time (predetermined frame) for the attractive force direction (attraction force direction parameter) currently applied to the moving object to reach the correction target value. Therefore, for example, when the moving speed of the moving object is fast, the next hit between the moving object and the landable object is detected before the correction target value is reached, so a new correction target value corresponding to the next hit surface is detected. Is set, and the process of correcting the attractive direction applied to the moving object (for example, the character) is performed so as to gradually approach the new correction target value corresponding to the next hit surface over a predetermined time. Therefore, when the moving object moves at a high speed (when it moves at a speed that the correction cannot catch up with the predetermined time for reaching the correction target value), the correction does not take place and it does not affect the character. The moving body object moves without changing the attractive direction (attraction force direction parameter) to be changed (not much changed from the initial value).

  Since the posture (basic posture) and the line-of-sight direction of a moving object are often set with reference to the direction of attractive force, according to the present invention, for example, the movement of the moving object and the movement of the line-of-sight direction are reduced.

  For example, in a first-person viewpoint game, the line of sight of the virtual camera is controlled in accordance with the character's posture (orientation). Therefore, if the character's posture (orientation) changes in response to the attractive force, the line of sight changes dramatically. Or the line-of-sight direction changes suddenly and does not become a game. However, according to the present invention, when the current attractive force direction and the attractive force direction set on the hit polygon surface are different, the line-of-sight direction does not change abruptly because it is adjusted stepwise (gradually) over a predetermined period.

  Further, even when the moving object moves on a bumpy surface, it can follow without a sense of incongruity due to bumps.

  Thus, according to the present invention, there are provided a program, an image generation system, and an information storage medium capable of performing natural and uncomfortable internal attractive force control for a moving object that is in a landing state with respect to a landable object. Can do.

Thus, a process of correcting the direction of attractive force applied to the moving object is performed.

(5) A program, an information storage medium and an image generation system according to the present invention include
The movement / motion calculation unit is
When no hit between the moving object and the landing object is detected for a predetermined period, the landing state for the landing object is canceled, and the process of applying the attractive force of the landing object to the moving object is stopped. .

  When the moving object is in the landing state, the position, speed, movement, and movement of the moving object are calculated based on the attraction and movement of the landing-capable object in the landing state and external input information.

  Then, hits of the moving object and the landing object are detected for each frame. You may make it detect the hit of a mobile body object and a landing possible object between the mobile body object and the attractive force setting object set corresponding to the landing possible object, for example.

  When the landing state is released, the state shifts to a non-landing state (for example, a floating state). In a non-landing state (for example, a floating state), the attractive force of the landable object is not applied, and the position, speed, movement, and movement of the moving object are calculated based on external input information related to movement.

  According to the present invention, for example, when the moving object is moving, for example, when the moving object temporarily leaves the landing object (when there is a frame where the moving object (eg, character) does not hit the landing object) ) However, if it is within a predetermined period (within a predetermined time or within a predetermined frame) from the previous hit, it is considered that the landing state is continuing, and movement control for placing in the landing state is performed. For this reason, for example, even when a mobile object (for example, a character) temporarily jumps or when the mobile object (for example, a character) and a landable object are temporarily separated because the ground plane is not flat, the landing state continues. Is considered to be.

  Here, the predetermined period can be set as appropriate.

  If the time is set too short, the landing state is released as soon as the mobile object and the landing object are separated from each other, and if the time is set too long, the mobile object (for example, a character) is set so that the player releases the landing state. The player's intention cannot be reflected when the movement is input. Therefore, the predetermined period is preferably set to an appropriate time according to the operability of the player.

(6) A program, an information storage medium, and an image generation system according to the present invention include
The movement / motion calculation unit is
When a hit between a moving object and a landable object in a non-landing state is detected, an attractive force action direction parameter is initially set based on the attractive force direction set on the hit surface as attractive force information.

  Detection of hits between a non-landing mobile object and a landable object may be performed using an attractive force setting object and a landable object image generation object, or an object prepared for hit checking may be used. May be used.

  According to the present invention, immediately after the moving object has landed on the landable object, the attractive force set on the landing surface is changed all at once. By doing in this way, an image without a sense of incongruity can be generated immediately after landing.

(7) A program, an information storage medium, and an image generation system according to the present invention include
The movement / motion calculation unit is
When a hit between the moving object and the attractive force setting object is detected, a direction difference between the attractive force direction parameter and the attractive force direction set in the polygon of the hit surface is detected. The direction difference between the attractive force direction parameter and the attractive direction set in the polygon of the hit surface is distributed to a preset correction period to obtain a correction amount per frame, and the correction amount for each frame is calculated with the obtained correction amount. The attractive force acting direction parameter is corrected to act on the moving object.

  In the present invention, a correction period up to the correction target value is defined, and the direction difference (direction of the direction) between the attractive force direction parameter (the attractive direction currently applied to the moving object) and the attractive direction set in the polygon of the hit surface. The amount of correction per frame is determined by appropriately allocating (angle difference) to the correction period (number of frames). At this time, the correction amount per frame may be distributed so as to be constant, or the correction amount per frame may be distributed differently.

  Here, “easy landing is possible” means that when a mobile object in a non-landing state and a landable object (attraction force setting object) are hit, the mobile object is in a landing state on the landable object. For example, even if a mobile object and a landable object hit, the landing state is set unless the mobile object hits in a predetermined posture, or the predetermined position (for example, a foot) of the mobile object does not hit. The setting which does not become easy landing is not possible.

  Also, “easy landing impossible” means that even if a non-landing mobile object and a landable object (attraction force setting object) are hit, the mobile object (for example, a character) cannot land on the landable object (for example, it collides but repels). Returned) and / or a case where the mobile object is not regarded as having landed unless it hits in a predetermined posture or position.

  The easy landing availability information may be information indicating that the surface constituting the attractive force setting object is a surface that can be easily landed, or may be information indicating that the surface is not easy landing.

  In the former case, if the moving object hits a surface that is set to be easy landing, the moving object is shifted to the landing state, and if it hits the other surface, it does not shift to the landing state (for example, it bounces back). ) Processing may be performed, or processing may be performed in which the moving object is not regarded as having landed unless it hits in a predetermined posture or position.

  In the latter case, a process that does not shift to a landing state (for example, bounces back) if a hit is made on a surface that is set to be incapable of easy landing, or a process that does not regard a landing unless the moving object hits in a predetermined posture or position. If the mobile object hits any other surface, the mobile object may be shifted to the landing state, or the mobile object is not regarded as having landed unless it hits in a predetermined posture or position. May be performed.

  According to the present invention, it is possible to land a surface on which easy landing is enabled by simply hitting the mobile object, so that the mobile object is hidden without difficult operations for controlling the posture of the mobile object. It is possible to shift from the landing state to the landing state.

  In addition, for example, when there is a place where landing is not permitted in a part of the landing-enabled object, the designer only needs to set easy landing on a surface corresponding to the place.

  Here, the game processing unit 110 receives coins (cost), various mode setting processing, game progress processing, selection screen setting processing, object position and rotation angle (rotation angle around X, Y, or Z axis). , Processing to move the object (motion processing), processing to determine the viewpoint position and line-of-sight angle (gaze direction), processing to place objects such as map objects in the object space, hit check processing, game results (results, results) ), Various game processes such as a process for a plurality of players to play in a common game space, a game over process, etc., from the operation data from the operation unit 160 and the portable information storage device 194. This is based on personal data, stored data, game programs, etc.

  The image generation unit 140 performs various types of image processing in accordance with instructions from the game processing unit 110 and the like. The sound generation unit 150 performs various types of sound processing in accordance with instructions from the game processing unit 110 and the like.

  Note that all of the functions of the image generation unit 140 and the sound generation unit 150 may be realized by hardware, or all of them may be realized by a program. Alternatively, it may be realized by both hardware and a program.

  The game processing unit 110 includes a movement / motion calculation unit 112, a viewpoint information calculation unit 114, and an object display control processing unit 116.

  The movement / movement calculation unit 112 calculates movement information (position data, rotation angle data) and movement information (position data of each part of the object, rotation angle data) of an object such as a character and a ball. Based on operation data input by the player through the operation unit 160, a game program, or the like, a process of moving or moving an object is performed.

  More specifically, the movement / motion calculation unit 112 performs processing for obtaining the position and rotation angle of the object every frame (1/60 seconds), for example. For example, the position of the object in the (k-1) frame is PMk-1, the speed is VMk-1, the acceleration is AMk-1, and the time of one frame is Δt. Then, the position PMk and speed VMk of the object in the k frame are obtained, for example, by the following equations (1) and (2).

PMk = PMk-1 + VMk-1 * .DELTA.t (1)
VMk = VMk-1 + AMk-1 * .DELTA.t (2)
In addition, when the moving object is in a landing state on the landing object, the movement / motion calculation unit 112 applies an attractive force that acts on the moving object in each frame based on the attractive information that the landing object acts on the moving object. An action direction parameter is determined, and an attractive force is applied to the moving object based on the attraction action direction parameter to calculate at least one of movement and movement of the moving object. Then, the hit of the moving object and the attractive force setting object is detected, and the direction difference between the attractive force direction parameter and the attractive force direction set on the hit surface is detected. Using the set attractive force direction as a correction target value, the correction amount per frame is determined so as to gradually approach the correction target value over a predetermined time, and the attractive force direction parameter is corrected with the determined correction amount. Thus, a process for correcting the attractive direction applied to the moving object is performed.

  In addition, when a hit between the moving object and the landing object is not detected for a predetermined period, the movement / motion calculation unit 112 cancels the landing state with respect to the landing object and applies the attractive force of the landing object to the moving object. The process may be stopped.

  In addition, when the movement / motion calculation unit 112 detects a hit between a non-landing moving object and a landingable object, the attractive direction set on the hit surface as attractive information is initially set as an attractive action direction parameter. You may make it do.

  When the movement / motion calculation unit 112 detects a hit between the moving object and the attractive force setting object, the movement / motion calculating unit 112 detects a direction difference between the attractive force acting direction parameter and the attractive force direction set in the polygon of the hit surface, If there is a direction difference, the direction difference between the attractive force direction parameter and the attractive direction set in the polygon of the hit surface is distributed over a preset correction period to obtain a correction amount per frame, The attractive force direction parameter of each frame may be corrected with the obtained correction amount so as to act on the moving object.

  Further, the movement / motion calculation unit 112 detects hits of the attractive force setting object and the moving object, and determines the correction amount of each frame until the correction target value is reached based on the correction information set on the hit surface. The attractive force direction parameter of each frame may be corrected with the determined correction amount.

  The movement / motion calculation unit 112 detects hits of the non-landing moving object and the attractive force setting object, determines whether easy landing is possible based on easy landing availability information set on the hit surface, If the landing is possible, a process of making the moving object land on the hit surface may be performed.

  Further, the movement / motion calculation unit 112 may perform processing for setting, adjusting, or changing the character posture based on the attractive force acting direction parameter.

  The movement / motion calculation unit 112 may perform processing for switching motion data based on whether the moving object is in a landing state or a non-landing state.

  The viewpoint information calculation unit 114 calculates the viewpoint position of the virtual camera or the position of the character based on the input information.

  Further, the viewpoint information may be set, corrected, or changed based on the attractive force direction parameter.

  The viewpoint information calculation unit 114 may perform processing for setting, correcting, or changing viewpoint information based on whether the moving object is in a landing state or a non-landing state.

  The object display control processing unit 116 detects hits or hit schedules of the non-landing mobile object and the attractive force setting object, and the easy display is performed based on the easy landing availability information set in the polygon of the hit or hit target plane. Whether landing is possible is determined. If easy landing is possible, display control may be performed to change the posture of the moving object in accordance with predetermined landing posture change information.

  In addition, when the object display control processing unit 116 receives an easy landing designation input from the operation unit when the non-landing moving object and the landing object are in a predetermined positional relationship, the object display control processing unit 116 receives predetermined landing posture change information. Display control for changing the posture of the moving object may be performed according to the above.

  Further, the object display control processing unit 116 detects hits or hit schedules of the moving object in the non-landing state and the attractive force setting object, and based on the easy landing availability information set in the polygon of the hit or hit target plane. Whether or not easy landing is possible is determined. If easy landing is possible, display control may be performed to change the shape of the moving object in accordance with predetermined shape change information.

2. Features and Operations of this Embodiment Next, features and operations of this embodiment will be described.

  2A and 2B are diagrams for describing the features of the present embodiment.

  A character object (an example of a moving object) 210 and a landable object (for example, a planet, a spacecraft, a meteorite, a ship, etc.) 220 are arranged and moved in the game space (for example, outer space) of this embodiment. The state where the character object 210 as shown in FIG. 2B does not land on the landable object 220 due to the movement of the body object, and the character object 210 as shown in FIG. It is configured to be able to move between each other. 2B and a non-landing state (floating state) as shown in FIG. 2A perform different attraction control on the moving object 210 to move the moving object 210. Let

  The mobile object 210 in the landing state as shown in FIG. 2B is displayed on the landing object on the basis of the movement vector F set by input information from the player and the attractive vector g set to the landing object. The movement operation is controlled.

  On the other hand, a moving object 210 in a non-landing state (floating state) as shown in FIG. 2A is a game space (for example, outer space or the like) based on a moving vector F set by input information from a player or the like. The movement movement within the landing possible object is controlled.

  The attractive force g is a force acting between two objects, and here, the focus is mainly on a portion where a landable object acts on a moving object. In this game, for example, a force such as gravity acting on an object on the earth (this force is referred to as an attractive force) is applied to the moving object in the landing state, and motion control is performed as if the attractive force is acting. Therefore, the gravitational force in the present invention may be gravity or pseudo-gravity, or may be other force that maintains the landing state (for example, force in the case where the mobile object such as a thruster (thrust) generates its own force).

  Here, the attractive direction is a direction component of an attractive vector g (magnitude and direction of attractive force) that acts on a moving object (for example, a character object).

  Note that the landable object 220 may be stationary or moving. When the moving object 210 is in a landing state on the moving landing object 220, the moving object 210 acts on the landing object 220 together with the attractive force g. As a result, the moving object 210 that is in the landing state and has not moved by itself is relatively stationary with respect to the landable object 220.

2-1 Landing Possible Object Information FIGS. 3A and 3B are diagrams for explaining information stored in the landing possible object information storage unit. FIG. 4 is a diagram illustrating the attractive force direction applied to the moving object set on each surface of the attractive force setting object.

  FIG. 3A is an example of an attractive force setting object set in accordance with the shape of the landable object. The attractive force setting object 250 is configured as a polygon object including a plurality of polygons P1, P2,. The attractive force setting object 250 may be shared with, for example, a model object for generating an image of a landable object, may be shared with a hit check object for hit checking of a landable object, or may be used for generating an image. This model may be simplified to set a dedicated attractive force setting object.

  FIG. 3B is a diagram for explaining various information stored in association with each surface of the attractive force setting object.

  In the landable object information storage unit according to the present embodiment, there is an attractive direction to be applied to the moving object in association with each surface (here, polygon surfaces) P1, P2,... Constituting the attractive force setting object 250. Various kinds of information including the set attractive force information are stored. For example, as shown in FIG. 3B, in correspondence with each polygon 310, polygon vertex information 320, polygon attraction direction information (normal line information) 330, easy landing availability information 340, attraction action direction correction pattern information 350 Etc.

  The vertex information 320 stores vertex coordinate data constituting the polygon, and is used for, for example, h hit check calculation.

  Polygon attraction direction information (normal line information) 330 is information on the direction of attraction acting on a moving object that hits the polygon surface. Here, as shown in FIG. 4, the attractive direction can be set in the direction opposite to the direction of the normal line of each surface 310. In such a case, polygon normal information can be used as attractive direction information.

  Note that as the information about the attractive force direction to be applied to the moving object, only the polygon attractive force direction may be set for the polygon (for example, if the size is the same for each surface, it may not be set for each surface). ), Vector information including direction and size may be set.

  The easy landing availability information 340 may be information indicating that the polygon surface is a surface that can be easily landed, or information indicating that the polygon surface is a surface that cannot be easily landed.

  “Easy landing is possible” means that when a character object in a non-landing state and a landable object hit, the character object will land on the landable object.

  “Easy landing impossible” means that even if a non-landing character object and a landable object hit, the character object cannot land on the landable object (for example, it collides but repels), and a mobile object (for example, a character) ) Means one or both of the cases where the landing is not considered unless it hits in a predetermined posture or position.

  3A and 3B, for example, “1” is set in the easy landing availability information 340 of the polygon P1, indicating that “easy landing is possible”. Therefore, when the character object hits the polygon P1 of the landable object (in any posture or position), the character object is landed on the landable object.

  Further, for example, “0” is set in the easy landing availability information 340 of the polygon P2, indicating that “easy landing is not possible”. Therefore, even if the character object hits the polygon P2 of the landable object (in any position or position in the present embodiment), the character object does not land on the landable object but is rebounded, for example. Such movement control is performed.

  In the attractive force direction correction pattern information 350, a correction pattern for the attractive direction to be applied to the character object hit on the polygon surface is set. For example, a pattern identification number is stored, and a correction pattern associated with each pattern identification number may be programmed or may be tabulated.

  As the correction pattern, for example, a pattern regarding how the correction amount is allocated to each frame until the correction target value is reached is stored. In this way, it is possible to correct the direction of attractive force acting on the character with an appropriate correction pattern according to the hit surface.

  Information that can be set in association with each surface of the attractive force setting object is not limited to the above. For example, information on whether landing is possible may be set. A surface for which landing is allowed means that landing is possible, and a surface for which landing is impossible means that landing is not possible. “Landing is possible” means that landing is possible according to a method preliminarily given in the game. Therefore, if you can land easily and land, you can land by hitting that surface. In addition, if it is a surface that cannot land with easy landing, it can land if it hits the surface with a predetermined posture and position determined by the game. If you are unable to land, you cannot land in any way.

  Therefore, it is easy to design because it is only necessary to set the landing impossible on the surface where it is difficult to land on the game.

2-2 Attraction Action Direction Correction Processing FIG. 5 is a diagram for explaining attraction action direction correction processing according to the present embodiment.

  It is assumed that the character object 210-0 that has been in a non-landing state (floating state) at time (frame) t0 has landed on the polygonal plane P1 of the landable object 220 at time (frame) t1.

  Since the character object 210-0 is in a non-landing state (floating state) at time (frame) t0, the attractive force from other objects does not act, and the movement vector Ft0 based on the input information and other game factors acts. The character object 210-0 is moved.

  At time (frame) t1, since the character object 210-1 has landed on the polygon plane P1 of the time landing object 220, the character object 210-1 moves to the landing state, and the attractive force from the landing object 220 is exerted. receive.

  An attraction vector g1 (an example of attraction direction information) is set on the polygon plane P1, and this is expressed as an attraction action direction Gt1 (attraction action direction parameter at time t1) acting on the character object 210-1 immediately after landing. The attractive force vector g1 is initialized.

  At time t1, a force for moving the character object 210-1 acts in the direction of the resultant force Bt1 of the movement vector Ft1 based on the input information and other game factors and the attractive force acting direction Gt1 (attractive force acting direction parameter at time t1).

  It is assumed that the character object 210-1 is moved by the resultant force Bt1 and hits the polygon surface S2 at time (frame) t2. An attraction vector g2 (an example of attraction direction information) is set on the polygon surface P2. The direction difference (angle difference α) between the attractive force acting direction Gt1 (attractive force acting direction parameter at time t2) currently applied to the character object 210-2 and the attractive force direction g2 set on the hit surface P2 is detected, and the direction When there is a difference (angle difference α), the attractive direction g2 set on the hit surface S2 is set as a correction target value, and the moving object is caused to gradually approach the correction target value over a predetermined time. A process of correcting the attractive direction is performed.

  For example, when correction is performed so that the correction target value is reached over n frames, the correction amount for each frame is set to α / n, and the attractive force applied to the character object until the next hit is detected in subsequent frames. The action direction (attraction force direction parameter) may be corrected by α / n so as to be based on the correction target value.

  In this way, the attractive force direction parameter holds the attractive force direction applied to the landing object in each frame, and the attractive force is applied to the landing object for each frame based on the attractive force direction parameter. It can be constituted as follows. Note that the attractive force direction parameter may be set, for example, as the initial value of the attractive force direction set on the first hit surface.

  The direction difference between the attractive force direction parameter and the attractive direction set on the hit surface may be, for example, an angular difference between directions.

  In the landing state, the moving object is subjected to the action of the attraction of the landable object, and the moving object in the landing state has a movement vector (speed, acceleration, or force vector) set by input information from the player, The moving position is determined based on the attractive direction (acceleration or force vector corresponding to the attractive force), and the object moves on the landable object.

  The landing state is a state where the moving object and the landing object are hit. A hit between a moving object and a landable object is detected every frame as the moving object moves, for example. If the hit between the mobile object and the landable object is not within a predetermined period (during a predetermined frame), it may be determined that the mobile object has transitioned from a landing state to a non-landing state (for example, a floating state). Good.

  In the present invention, when a mobile object hits a landable object, even if the attractive force direction set on the hit surface is different from the attractive force direction parameter (the attractive force direction currently applied to the mobile object), Or (in one frame), the attractive force direction parameter (the attractive force direction currently applied to the moving object) is not corrected to the attractive force direction set on the hit surface, but is set to the polygon of the hit surface. Using the attractive direction as a correction target value, a process for correcting an attractive force direction parameter that is applied to the moving object so as to gradually approach the correction target value over a predetermined time is performed.

  It takes a predetermined time (predetermined frame) for the attractive force direction (attractive force direction parameter) currently applied to the moving object to reach the correction target value. Therefore, for example, when the moving speed of the moving object is fast, the next hit between the moving object and the landable object is detected before the correction target value is reached, so a new correction target value corresponding to the next hit surface is detected. Is set, and the process of correcting the attractive direction applied to the moving object (for example, the character) is performed so as to gradually approach the new correction target value corresponding to the next hit surface over a predetermined time. Therefore, when the moving object moves at a high speed (when it moves at a speed that the correction cannot catch up with the predetermined time for reaching the correction target value), the correction does not take place and it does not affect the character. The moving object moves without changing the attractive direction (attraction force direction parameter) to be changed (not much changed from the initial value) (see FIG. 8A).

  Since the posture (basic posture) and the line-of-sight direction of a moving object are often set with reference to the direction of attractive force, according to the present invention, for example, the movement of the moving object and the movement of the line-of-sight direction are reduced.

  For example, in a first-person viewpoint game, the line of sight of the virtual camera is controlled in accordance with the character's posture (orientation). Therefore, if the character's posture (orientation) changes in response to the attractive force, the line of sight changes dramatically. Or the line-of-sight direction changes suddenly and does not become a game. However, according to the present invention, when the current attractive force direction and the attractive force direction set on the hit polygon surface are different, the line-of-sight direction does not change abruptly because it is adjusted stepwise (gradually) over a predetermined period.

  Further, even when the moving object moves on a bumpy surface, it can follow without a sense of incongruity due to bumps.

  FIG. 6 is a flowchart for explaining the correction processing of the present embodiment.

  First, a movement amount is generated in the current attractive force acting direction and added to a movement vector (movement vector generated by an element other than the attractive force) (step S10).

  Next, a hit check is performed with the landable object for the added movement vector direction (step S20).

  If there is no hit, the process goes to step S60. If there is a hit, the attractive direction set on the hit surface is set as the correction target value, and the correction amount per frame is obtained (steps S30, S40).

  Next, the attractive direction set on the hit surface is set as a new posture target of the character object (step S50).

  Based on the determined correction amount, the attractive force acting direction is corrected (step S60).

  Further, the current posture of the character object is corrected so as to be linked to the correction target value (step S70).

  FIGS. 7A and 7B are diagrams for explaining the correction value of the attractive force acting direction.

  FIGS. 7A and 7B show the angle difference 410 between the attractive force acting direction at the time of the hit and the attractive force direction (correction target value) set on the hit surface, and correction of each frame until the next hit is detected thereafter. It is the figure which showed the relationship of quantity 420. FIG. As shown in FIG. 7A, the correction may be performed with a constant correction amount every frame regardless of the angle difference 410. Further, as shown in FIG. 7A, the correction amount per frame may be increased as the angle difference 410 increases. The angle difference 410 and the correction amount per frame may be proportional (synonymous with a configuration in which the correction time is the same regardless of the angle difference).

  In the above description, the correction amount per frame is the same or the correction amount per frame is the same as long as the angle difference is the same. However, the present invention is not limited to this. For example, the correction amount may be changed according to the elapsed time from the start of correction (the correction amount may not be set uniformly in each frame).

  FIGS. 8A and 8B are diagrams for explaining the effect of the correction processing of the present embodiment.

  FIG. 8A shows the posture of the character object in each of the frames f1, f2, f3,... When the moving speed is fast, and FIG. 8B shows each frame f1 when the moving speed is slow. , F2, f3,...

  In the present embodiment, processing for setting, adjusting, or changing the posture S of the character is performed based on the attractive direction acting on the character object. Specifically, a natural image without a sense of incongruity can be generated by matching the basic posture of the character with the attractive direction currently acting on the character.

  Further, in the present embodiment, processing for setting, adjusting, or changing viewpoint information (virtual camera position, line-of-sight direction K, angle of view, etc.) is performed based on the direction of attractive force acting on the character object 210. Specifically, the line-of-sight direction K may be set to a direction orthogonal to the attractive direction acting on the character object 210.

  As shown in FIG. 8A, when the moving speed of the character object 210 is fast, the next hit is detected earlier than the correction to the correction target value, so that it is hardly corrected (for example, the initial setting) Will move). Here, the attractive directions g1, g2, g3, and g4 are set on the hit surfaces (landing surfaces) P1, P2, P3, and P4, respectively, and the attractive directions g1, g2, g3, and g4 have a considerable angular difference. ing.

  However, when the moving speed of the character object 210 is fast, the character object 210 can be moved almost without being affected by the change in the attractive direction.

  At the same time, the character object 210 can be moved with almost no change in the character's posture or line-of-sight direction. Accordingly, it is possible to move the character object on the landing object without causing the game screen to be shaken and the player's feeling of operation uncomfortable. In such a fast movement, the influence of the unevenness of the ground is not affected by the operation feeling of the player, and the vehicle can be run without a sense of incongruity.

  As shown in FIG. 8B, when the moving speed of the character object 210 is slow, the next hit is detected after the correction to the correction target value is performed to some extent, so that the character object 210 moves while being corrected to some extent. become. Here, the attractive directions g1, g2, g3, and g4 are set on the hit surfaces (landing surfaces) P1, P2, P3, and P4, respectively, and the attractive directions g1, g2, g3, and g4 have a considerable angular difference. ing.

Therefore, when the moving speed of the character object 210 is slow, the character object 210 can be moved while being affected by the change in the attractive direction. In such a slow movement, the influence of the unevenness of the ground is consistent with the player's sense of operation and can be run without a sense of incongruity. At the same time, the character object 210 changes while changing the character's posture and line of sight. Can be moved. Therefore, although the game screen is shaken at some point, this is a change in the posture or line of sight reflecting the unevenness of the ground, and the player can move the character object on the landing object without feeling uncomfortable.

2-3 Landing state non-landing (state floating state) switching control process When the mobile object 210 is in the landing state as shown in FIG. 2B, for example, as described with reference to FIG. 5, landing is possible Based on the external input information relating to the attractive force and movement of the object 220, the position, speed, movement and movement of the moving object are calculated.

  Then, hits of the moving object and the landing object are detected for each frame. You may make it detect the hit of a mobile body object and a landing possible object between the mobile body object and the attractive force setting object set corresponding to the landing possible object, for example.

  When the landing state is canceled, the state shifts to a non-landing state (for example, a floating state) as shown in FIG. In the non-landing state (for example, floating state), as described with reference to FIG. 5, the attractive force of the landable object is not applied, and the position, speed, movement, and movement of the moving object are calculated based on external input information related to movement. The

  According to the present invention, for example, when the moving object is moving, for example, when the moving object temporarily leaves the landing object (when there is a frame where the moving object (eg, character) does not hit the landing object) ) However, if it is within a predetermined period (within a predetermined time or within a predetermined frame) from the previous hit, it is considered that the landing state is continuing, and movement control for placing in the landing state is performed. For this reason, for example, even when a mobile object (for example, a character) temporarily jumps or when the mobile object (for example, a character) and a landable object are temporarily separated because the ground plane is not flat, the landing state continues. Is considered to be.

  Here, the predetermined period can be set as appropriate.

  If the time is set too short, the landing state is released as soon as the mobile object and the landing object are separated from each other, and if the time is set too long, the mobile object (for example, a character) is set so that the player releases the landing state. It is not reflected when the movement is input. Therefore, the predetermined period is preferably set to an appropriate time according to the operability of the player.

  FIG. 9 is a flowchart for explaining the landing state non-landing (state floating state) switching control process of the present embodiment.

  When the player character (an example of a moving object) is in a non-landing state (floating state), the movement vector of the player character from the input from the player or other attractive forces (excluding the attractive force that the landingable object acts in the landing state), etc. Is calculated (step S110).

  Next, landing determination on the landing possible object in the moving direction of the player character (hit check between the player character and the landing possible object) is performed based on the movement vector (step S120).

  When the landing is not detected (no hit), the process returns to step S110 and the processes of steps S110 to S130 are repeated. When the landing is detected (hit is found), the following process is performed.

  First, the attribute of the character object is changed to the landing state, and 0 is set to the no-hit duration T (a variable for counting the no-hit duration) (step S140).

  Next, the attractive direction set on the landing is initially set as the attractive force acting direction on the character (step S150).

  Next, the movement vector of the player character is calculated from the input from the player and other attractive forces (excluding the attractive force at which the landingable object acts in the landing state), etc. (step S160).

  A movement amount is generated in the current attractive force acting direction and added to the movement vector obtained in step S160 (step S170).

  Next, landing determination (hit check) is performed on the object that can be landed on the assumption that the character is at the position moved by the movement vector obtained in step S170 from the current position.

  If there is no hit, the process returns to step S140, and the processes of steps S140 to S180 are repeated. If the hit is found, the following process is performed.

  The hitless duration T is added (incremented) (step S200).

  Then, it is determined whether the non-hit duration T is greater than or equal to a predetermined value X. If it is greater than or equal to the predetermined value, the attribute of the character object is changed to a non-landing state (floating state) and the process returns to step S110.

If it is not greater than the predetermined value, the process returns to step S160.
2-4 Easy Landing Process FIG. 10 is a flowchart for explaining the easy landing process according to the present embodiment.

  First, the movement vector of the character object in the non-landing state is calculated from the input from the player and other attractive forces (excluding the attractive force acting when the landingable object is in the landing state), etc. (step S310).

  Based on the movement vector, a landing hit check is performed on a landable object in the movement direction (step S320).

  If there is no hit, the process returns to step S310 and the processes of steps S310 to S330 are repeated. If a hit is found, the following process is performed (step S330).

  It is determined whether the hit location can be easily landed (step S340). For example, as described with reference to FIGS. 3 (A) and 3 (B), whether or not easy landing is possible based on the easy landing availability information of the hit surface is performed by performing a hit check with an attractive force setting object having easy landing availability information set on each surface. You may make it determine.

  If easy landing is possible, landing processing is performed (steps S350 and S360).

  If easy landing is not possible, a normal landing possibility determination is performed (steps S350 and S370). It is a process for determining whether landing is possible when a normal landing possibility determination and when a character object hits in a predetermined posture or hits at a predetermined position (for example, a leg of a character object).

  When normal landing is possible, landing processing is performed (steps S380 and S360), and when normal landing is not possible, collision processing is performed (steps S380 and S390).

  FIG. 11 is a flowchart for explaining an easy landing process in the present embodiment when a landing destination is predicted and landing preparation is performed.

  First, the movement vector of the character object in the non-landing state is calculated from the input from the player and other attractive forces (excluding the attractive force that the landing-able object acts in the landing state), etc. (step S410).

  Based on the movement vector, a landing hit check is performed on a landable object in the movement direction (step S420).

  If there is no hit, the process from step S500 to step S520 is performed, and the process returns to step S410.

  It is determined whether there is an easy landing possible place at an arbitrary movement prediction destination (step S500).

  If easy landing is not possible, the process returns to step S410. If easy landing is possible, landing preparation is performed and the process returns to step S410 (steps S510 and S520).

  If there is a hit in step S420, it is determined whether the hit location can be easily landed (step S440). If easy landing is possible, landing processing is performed (step S460).

  If easy landing is not possible, a normal landing determination is performed (step S470). It is a process for determining whether landing is possible when a normal landing possibility determination and when a character object hits in a predetermined posture or hits at a predetermined position (for example, a leg of a character object).

  When normal landing is possible, landing processing is performed (steps S480 and S460), and when normal landing is not possible, collision processing is performed (steps S480 and S490).

  12A and 12B are diagrams for explaining an example of the landing process according to the present embodiment.

  For example, as shown in FIG. 12A, it is assumed that the character object hits a landable object at time t3 by moving like 210-1, 210-2, 210-3 at times t1, t2, and t3. .

  In such a case, in this embodiment, as shown in FIG. 12B, the hit plane is an easy landing plane, and the posture of the character that can be placed at time t3 is changed to the landing basic posture. The landing basic posture is a posture in which the gravitational force direction g set on the hit surface and the posture direction S are the same.

  The attribute of the player character is in a landing state and is subjected to the action of the attraction of the landingable object that has landed.

  FIG. 13 is a diagram for describing attitude control during easy landing according to the present embodiment.

  In this embodiment, when the character object 210-1 in the non-landing state and the landable object 220 are in a predetermined positional relationship, when an easy landing designation input is received from the operation unit, or the planned contact surface is the easy landing surface. In this case, display control of the character object is performed according to landing posture change information prepared in advance. Here, the predetermined positional relationship is, for example, a case where the distance between the character object 210-1 and the landable object 220 is within a predetermined distance.

  For example, as shown in FIG. 13, at time t1 to t4, the process of gradually changing from the character object 210-1 to the landing posture as in S1 to S4 of the posture (rotation) 210-4 is performed irrespective of the player input.

  For example, the estimated landing time t4 is obtained based on the distance between the character object 210-1 and the landable object 220 and the moving speed of the character object, and the character object posture S1 at the landing posture start time t1 and the character object posture S4 at t4. Find the direction difference (angle difference). Then, the obtained direction difference (angle difference) may be distributed to the estimated landing time (scheduled number of frames) to determine the correction amount for each frame, and the posture of the character placed in each frame may be corrected.

  By doing so, the player can perform an image effect of the posture change of the player character without performing an operation input for complicated posture control.

  FIGS. 14A and 14B are diagrams for describing shape change control during easy landing according to the present embodiment.

  FIG. 14A shows a state where a mobile object having the shape of an airplane lands on a landable object.

  FIG. 14B shows a state in which the shape of the moving object having the shape of an airplane landing on the landable object changes to a vehicle.

  In the present embodiment, as shown in FIG. 14B, hits or hit schedules of the non-landing mobile object 510 and the landable object 220 are detected and set as polygons on the hit or hit plane. Whether easy landing is possible is determined based on the easy landing availability information. If easy landing is possible, display control is performed to change the shape of the moving object (for example, the character) according to the shape change information prepared in advance.

  The shape may be changed instantaneously at the time of landing as shown in FIG. 14B, or may be changed gradually from the landing posture start time t1 to the scheduled landing time t4. In the latter case, the airplane model and the vehicle model are displayed at the same time, and one plane (here, the vehicle model) is faded in, while the other (here, the airplane model) is faded out. The shape change of the body object can be realized.

  FIGS. 15A and 15B are diagrams for describing motion data switching control according to the present embodiment.

  O1 in FIG. 15A indicates a motion control point of the moving object 210 in the non-landing state (floating state), and O2 in FIG. 15B indicates the moving object 210 in the landing state. The control point of motion is shown.

  Here, the motion control point is a point that serves as a reference point when the object is placed in the world coordinate system as a representative point of the object. For example, in the first person viewpoint (or the third person viewpoint is possible), the position of the virtual camera may be determined based on the position of the control point.

  As described above, in the present embodiment, processing for switching motion data (here, since the control point is switched, the motion data itself also needs to be switched) depending on whether or not the moving object 210 is in the landing state. Do.

  As shown in FIG. 15A, in the non-landing state (floating state), the motion control point O1 of the moving object 210 is near the center of the moving object, and in the landing state, the motion control point O2 of the moving object 210 is Near the feet of the moving object.

Accordingly, the motion data to be used differs between the non-landing state (floating state) and the landing state. That is, in the non-landing state (floating state), the motion data in which the control point is set near the center of the moving object 210 is used, and in the landing state, the motion data in which the control point is set near the foot of the moving object 210 is used. To do. Therefore, in the landing state, it is possible to use the motion data of the game played on the conventional ground.
