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

  Conventionally, a game system (image generation system) that generates an image that can be seen from a given viewpoint (virtual camera) in a game space (object space) that is a virtual three-dimensional space is known. It's very popular as a product that can Taking a game system that can enjoy a racing game as an example, a player uses an operation unit (game controller, etc.) to perform operations (steering operation, shift operation, accelerator operation, etc.) related to a moving body (car, ship, airplane, etc.) Brake operation, etc.) and enjoy the racing game by competing with other players (including computer players) for moving and ranking.

By the way, in the above-described game system for performing the racing game, when the moving bodies approach each other in the front-rear relationship, the movement control of the moving body is performed in consideration of the slip stream phenomenon in which the speed and acceleration of the rear moving body increase. The technique to perform is proposed (refer patent documents 1 and 2).
Japanese Patent No. 3403505 JP 2000-140436 A

  However, in the above-described conventional game system, it is difficult for a moving body operated by a beginner who is not skilled in operation techniques to approach the moving body of the competitor itself, and dead heat with the competitor using the slipstream phenomenon is difficult. It was difficult to enjoy. In addition, when a plurality of players form a group and the groups play a race game against each other, the difference in skill between players within the same group greatly affects the result of the race game, In particular, in a group having beginners who are inexperienced in operation techniques, there is a problem that the beginners are separated from other players in the same group and cannot fully enjoy the dead heat with other groups.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an operation interface environment so that even a beginner who is unfamiliar with the operation can enjoy a race game in a group competition even when they are in a group. It is an object of the present invention to provide a game system, a program, and an information storage medium that are improved.

  (1) The present invention is a game system for playing a racing game in which a plurality of moving bodies form a group, and the moving bodies are placed in a game space based on the moving performance set for each of the moving bodies. Based on the fact that the moving object control unit that performs the moving control, the positional relationship determination unit that determines the positional relationship of each moving object in the game space, and the positional relationship of each moving object that belongs to the same group is a predetermined positional relationship. The present invention relates to a game system including a moving performance changing unit that changes the moving performance of a moving body. The present invention also relates to a program that causes a computer to function as each of the above-described units and a computer-readable information storage medium that stores such a program.

  “Moving performance” means acceleration, moving speed, maximum speed, etc. of a moving object, and “changing moving performance” means changing arithmetic coefficients that determine acceleration, moving speed, maximum speed, etc. In addition, addition or subtraction of an arbitrary value with respect to the acceleration, the moving speed, the maximum speed, etc. before the change is also included.

  According to the present invention, the moving performance of the moving body is changed based on the fact that the positional relationship of the moving bodies belonging to the same group is a predetermined positional relationship. Even if the senior and the senior group form a group, the advanced user operates the mobile body so as to construct a predetermined positional relationship according to the position of the mobile body of the beginner. The racing game can be advantageously advanced while changing the movement performance. Therefore, according to the present invention, even if there are beginners who are unfamiliar with the operation, the operation interface that allows the players to fully enjoy the racing game in a group competition while actively cooperating with each other and enhancing mutual cooperation. An environment can be provided.

  (2) The game system according to the present invention further includes an area setting unit that sets a predetermined area with respect to the game space based on the position of each moving body, and the positional relationship determination unit includes a given moving body. It is determined, as the positional relationship, whether or not another moving body exists in the predetermined area set based on the position, and the movement performance changing unit is within the predetermined area of the other moving body. The degree of change in the movement performance of the other moving body is set according to the position of the other moving body, the movement performance of the other moving body is changed according to the set degree, and the given moving body is You may make it change the degree to which the movement performance of the said other mobile body is changed according to whether it is the same group as another mobile body. In the program and the information storage medium of the present invention, the computer may function as the area setting unit, the positional relationship determination unit, and the movement performance change unit.

  In this way, regardless of the moving body, the moving performance can be changed by allowing the moving body to stay in a predetermined area set behind the arbitrary moving body. For example, the predetermined area set behind the moving bodies of different groups depends on whether or not the predetermined area is an area set behind the moving bodies belonging to the same group. The movement performance of the moving body changes when the movement performance of the moving body changes within a predetermined area set behind the moving body of the same group, compared to the case where the movement performance of the moving body changes within If the degree of movement is made advantageous, mobile players belonging to the same group will actively move to each other in a predetermined area set behind each other, and actively use cooperative play to improve each other's movement performance. So it is possible to provide the operation interface environment not in the racing game until now that it is possible.

  (3) The game system of the present invention further includes an area setting unit that sets a predetermined area with respect to the game space based on the position of each moving body, and the positional relationship determination unit includes a given moving body. It is determined whether or not there is another moving body in the predetermined area set based on the position, and whether or not the other moving body has moved out of the predetermined area from within the predetermined area. And after the movement performance changing unit changes the movement performance of the other moving body staying in the predetermined area and the other moving body moves outside the predetermined area. Also, in the given period set according to the period during which the other moving body stays in the predetermined area, a process of maintaining the state in which the moving performance of the other moving body has changed is performed, Other moving objects present in the area of the given Depending on whether or not the moving body and the same group, it may be to vary the period for maintaining the state in which the moving performance has changed in the other mobile. In the program and the information storage medium of the present invention, the computer may function as the area setting unit, the positional relationship determination unit, and the movement performance change unit.

  “Maintain the state in which the movement performance has changed” means that the movement performance will remain the same for a given period, and will return to the original movement performance while changing the movement performance in the given period. The case of making it include is also included. That is, “maintaining the state in which the movement performance has changed” means that the movement performance of the moving object is maintained different from the original movement performance.

  In this way, any moving body can be moved to a predetermined position if the moving performance is changed by staying in a predetermined area set behind any moving body. Even when moving outside the area, the state in which the movement performance has changed in a given period is maintained, but whether or not the stayed area is a predetermined area set behind a moving body belonging to the same group For example, the movement of the same group is more than the case where the moving body stays in a predetermined area set behind the moving body of a different group because the period during which the movement performance is changed varies depending on If the moving body stays in a predetermined area set behind the body, if the period during which the moving performance is changed is favored, the moving bodies belonging to the same group Predetermined to be set behind While moving alternately in the area, it is possible to provide the operation interface environment not in the racing game until now that the cooperation play that the movement performance go there enhance each other can be actively utilized.

  (4) In the game system, the program, and the information storage medium of the present invention, the area setting unit invalidates the predetermined area and the process of changing the size of the predetermined area based on the occurrence of the predetermined event. You may make it perform at least one of the process to perform.

  In addition to the case where the player performs a specific operation on the operation unit, the “predetermined event occurrence” includes a case where the moving body passes a specific area in the game space or a specific item for the moving body. It is included when equipped.

  Further, “changing the size of the predetermined region” includes both expanding the area of the predetermined region and reducing the area of the predetermined region.

  “Invalidate a predetermined area” means that the predetermined area is formally set in addition to the case where the predetermined area itself is not set, but there is a moving object in the area. This also includes the case where the calculation for changing the moving performance of the moving body is not performed.

  In this way, it is possible to give undulations to the development of the race game using a predetermined area set behind each moving body.

  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim.

  The portable information storage device 194 stores player personal data, game save data, and the like. Examples of the portable information storage device 194 include a memory card and a portable game device. The communication unit 196 performs various controls for communicating with the outside (for example, a host device or other image generation system), and functions thereof are hardware such as various processors or communication ASICs, programs, and the like. It can be realized by.

  Note that a program (data) for causing a computer to function as each unit of the present embodiment is distributed from the information storage medium of the host device (server) to the information storage medium 180 (storage unit 170) via the network and communication unit 196. May be. Use of the information storage medium of such a host device (server) can also be included in the scope of the present invention.

  The processing unit 100 (processor) performs processing such as game processing, image generation processing, or sound generation processing based on operation data and programs from the operation unit 160. The processing unit 100 performs various processes using the main storage unit 172 in the storage unit 170 as a work area. The functions of the processing unit 100 are hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs. Can be realized.

  The processing unit 100 includes a game processing unit 110, a drawing unit 120, and a sound generation unit 130. Note that some of these may be omitted.

  The game processing unit 110 is a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for arranging an object (display object) such as a moving object or a course, a process for displaying an object, A process for calculating the result or a process for ending the game when the game end condition is satisfied is performed. In particular, in the present embodiment, as a process for controlling the progress of the race game, the time for the moving body to go around the course set in the object space (game space) is measured, and the last turn in the group is finished. Using the time of the moving body as the time of the group, a process of comparing and determining the times of the groups and determining the rank of the group is performed. Of course, the time obtained by summing the lap times of all the mobile bodies belonging to the group may be processed as the group time, or the time of the mobile body that has finished the earliest in the group is processed as the group time. You may do it.

  In the game system of the present embodiment, the game processing unit 110 includes a display control unit 111, a moving body control unit 112, a slip stream region setting unit 113 (an example of a region setting unit), a positional relationship determination unit 114, and a travel performance change unit. 115 (an example of a movement performance changing unit) and a communication control unit 116.

  The display control unit 111 performs display control of an image (object image) displayed on the display unit 190. Specifically, an object to be displayed (car (moving body), course, building, tree, pillar, wall, map) is generated, the display or display position of the object is indicated, or the object is deleted. Display control. That is, display control such as registering the generated object in the object list, transferring the object list to the drawing unit 120, or deleting the disappeared object from the object list is performed.

  Further, the display control unit 111 displays an image indicating the movement or movement that occurs when a movement or movement of a player moving body (moving body that is an operation target of the player) or an object occurs according to input information of the player or the like. Control for displaying on the display unit 190 is performed.

  In particular, in the game system of the present embodiment, the game space is set by a three-dimensional object space, and the display control unit 111 also performs object space setting processing, virtual camera control processing, and the like.

  In the object space setting process, various objects (polygons, free-form surfaces, subdivision surfaces, etc.) representing display objects such as cars (moving objects), airplanes (moving objects), courses, buildings, trees, pillars, walls, maps, etc. The object is configured to be placed in the object space. In other words, the position and rotation angle of the object in the world coordinate system (synonymous with direction and direction) are determined, and the rotation angle (rotation angle around the X, Y, and Z axes) is determined at that position (X, Y, Z). Arrange objects.

  In the virtual camera control process, a virtual camera (viewpoint) control process for generating an image that can be viewed from a given (arbitrary) viewpoint in the object space is performed. Specifically, processing for controlling the position (X, Y, Z) or rotation angle (rotation angle about the X, Y, Z axis) of the virtual camera (processing for controlling the viewpoint position, the line-of-sight direction or the angle of view) I do.

  For example, when a moving body (for example, a car, an airplane, etc.) is photographed from behind using a virtual camera, the position or rotation angle of the virtual camera (virtual camera is set so that the virtual camera follows changes in the position or rotation of the moving body. The direction). In this case, the virtual camera can be controlled based on information such as the position, rotation angle, or speed of the moving body obtained by the moving body control unit 112 described later. Alternatively, the virtual camera may be controlled to rotate at a predetermined rotation angle or to move along a predetermined movement path. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or rotation angle of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  The moving body control unit 112 performs a movement / motion calculation (movement / motion simulation) of a moving body (for example, a car, an airplane, etc.). That is, based on operation data input by the player through the operation unit 160, a program (movement / motion algorithm), various data (motion data), or the like, the moving body is moved in the object space, or the moving body is operated (motion , Animation). Specifically, the movement information (position, rotation angle, speed, or acceleration) and movement information (position or rotation angle of each part constituting the moving body) of the moving body is obtained every frame (1/60 second). The simulation process is sequentially obtained. The frame is a unit of time for performing the moving / movement process (simulation process) and the drawing process of the moving object.

In particular, in the present embodiment, the moving body control unit 112 performs control to move the moving body in the object space (game space) based on the running performance (an example of moving performance) set for each moving body. Specifically, control for moving the moving body is started based on operation data from the operation unit 160, and the moving amount (moving body) in units of frames based on an acceleration coefficient that is a running performance set for each moving body. And the amount of rotation of the moving body in units of frames (rotational speed of the moving body) is calculated to obtain the coordinate transformation matrix M of the moving body. Note that the maximum speed, which is the upper limit value of the moving speed, is set as the traveling performance for each moving body, and the moving amount of the moving body in units of frames is limited by the maximum speed for each moving body. Then, the vertex coordinate P _K-1 of the moving object in the ( _K−1 ) th frame is multiplied by the coordinate transformation matrix M to obtain the vertex coordinate P _K (= P _K−1 × M) of the moving object in the Kth frame. Looking for.

  The slip stream area setting unit 113 performs a process of setting a slip stream area (an example of a predetermined area) for the object space (game space) based on the position of each moving object.

  More specifically, a substantially rectangular slip stream area is generated in an area behind the moving body in a course (for example, composed of polygons) that defines a moving path of the moving body set in the object space. In the present embodiment, a local coordinate system having a coordinate axis along the traveling direction of the moving body and a coordinate axis perpendicular thereto is set with respect to the course, and the slip stream is provided behind the moving body using the local coordinate system. An area is set. The shape of the slip stream region may be set so as to maintain a constant shape without being affected by the course shape, or may be set so as to be deformed in accordance with the course shape.

  Note that the slip stream area setting unit 113 may execute a process of changing the size of the slip stream area or a process of invalidating the slip stream area based on the occurrence of a predetermined event.

  For example, an item flag that is set when the moving object wears an item is prepared, and when the item flag is on, a slipstream area that is set behind the moving object according to the type of the item flag Can be enlarged or reduced. If another item flag is on, the slip stream area is not set behind the moving object, or the traveling performance is maintained even if the moving object stays in the slip stream area set behind the moving object. For example, the slip stream region may be invalidated by preventing the change from being changed. When the slip stream area is invalidated, the slip stream area is invalidated only for a mobile body in a group different from the mobile body on which the item is mounted. You may make it an area | region become effective. Further, for example, when the moving body passes a predetermined area on the course, the slip stream area may be enlarged or reduced, or the slip stream area may be invalidated.

  Further, the display control unit 111 may perform processing for identifying and displaying the slip stream area for each moving object. In this case, based on the group setting information stored in the main storage unit 172, the slip stream area of the moving body belonging to the same group as the moving body of the player and the slip of the moving body belonging to a different group from the moving body of the player. The group may be identified according to the display mode of the slip stream area by displaying the stream area in a different color.

  The positional relationship determination unit 114 performs processing for determining the positional relationship of each moving object in the object space (game space). For example, the positional relationship is whether or not another moving body (other moving body) exists in the slipstream region set based on the position of the moving body moving on the course set in the object space. At the same time, it is determined whether or not the moving object staying in the slip stream area has moved out of the slip stream area. In this case, based on the position of the representative point of each moving body in the local coordinate system for setting the slip stream area on the course, the moving body stays in the slip stream area, and the moving body slips. It can be determined that the object has moved out of the stream area.

  The travel performance changing unit 115 performs a process of changing the travel performance of the mobile body based on the fact that the positional relationship between the mobile bodies belonging to the same group is a predetermined positional relationship. As a process for changing the traveling performance of the moving object, for example, the moving amount of the moving object obtained by the moving object control unit 112 is multiplied by the effect magnification coefficient (> 1) to obtain the speed of the moving object. Process to raise.

  More specifically, based on the determination result in the position determination unit 114, an effect magnification factor (a degree of change in running performance) corresponding to the position of the moving body in the slip stream region is set and set. Multiplying the moving amount of the moving body in units of frames by the effect magnification factor increases the speed of the moving body (the amount of movement in the game space).

  In the game system of the present embodiment, a plurality of moving bodies that travel on the course in the object space (game space) are grouped in units of two or more moving bodies. Depending on whether or not the slip stream area where the moving body is staying is the slip stream area set for the moving body of the same group, the effect magnification coefficient for increasing the speed of the moving body is also changed. ing. The setting information of the group to which each moving body belongs is stored in the main storage unit 172 based on a selection operation or the like from the operation unit 160 of the player prior to the start of the game. For example, when a moving body operated by a player stays in a slipstream area set behind a moving body in the same group, the moving body operated by a player falls within a slipstream area set behind a moving body in a different group. The effect magnification coefficient can be set higher than when staying.

  In the game system of the present embodiment, the running performance change unit 115 monitors the period during which the moving body stays in the slip stream area, and after the moving body moves from the slip stream area to the outside of the slip stream area. In addition, processing is performed to maintain the state in which the traveling performance of the moving body has changed in a given period set in accordance with the period during which the moving body has stayed in the slipstream region. For example, the longer the period during which the mobile body stays in the slipstream region, the longer the traveling performance can be maintained.

  In addition, the traveling performance changing unit 115 changes the traveling performance of the moving body depending on whether or not the slipstream area where the moving body has stayed is a slipstream area set behind the moving body belonging to the same group. The process which changes the period which maintains the state which performed is performed. For example, when a moving body operated by a player stays in a slipstream area set behind a moving body of the same group, the moving body operated by a player falls within a slipstream area set behind a moving body of a different group. Control can be performed so that the state in which the running performance has changed is maintained for a longer period than when the user is staying.

  When the moving body stays in a specific area in the slip stream area for a certain period, the timing for starting the process of maintaining the state in which the traveling performance of the moving body has changed may be changed. For example, in an area where the effect magnification factor for increasing the speed of the moving body is set to be high, the process of maintaining the state in which the traveling performance of the moving body has changed is started early to suitably adjust the balance of the racing game. Can do.

  The communication control unit 116 generates a packet to be transmitted to another game system, specifies a network address of the game system that is the packet transmission destination, stores the received packet in the storage unit 170, and analyzes the received packet And the control processing of the communication unit 196 related to other packet transmission / reception. In particular, in the present embodiment, control for generating data packets and command packets necessary for running a racing game using a network (for example, the Internet), and transmission and reception of data packets and command packets via the communication unit 196 are performed. Take control.

  The drawing unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. When a so-called three-dimensional game image is generated, first, vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex defining a display object (object, model) is included. Display object data (object data, model data) is input, and vertex processing is performed based on vertex data included in the input display object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary. In vertex processing, geometry processing such as vertex movement processing, coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, perspective transformation, or light source processing is performed, and the display object is configured based on the processing result. The given vertex data is changed (updated, adjusted) for the vertex group. Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (fragment processing) for drawing pixels constituting an image (fragments constituting a display screen) is performed. In pixel processing, various processes such as texture reading (texture mapping), color data setting / changing, translucent composition, anti-aliasing, etc. are performed to determine the final drawing color of the pixels that make up the image, and perspective transformation is performed. The drawing color of the object is output (drawn) to the drawing buffer 174 (buffer that can store image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) set in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  The vertex processing and pixel processing performed by the drawing unit 120 are realized by hardware that enables polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). May be. Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of rendering processing is high, and the expressive power can be greatly improved compared to fixed rendering processing by hardware. .

  The drawing unit 120 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing the display object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the display object. Then, display object data after geometric processing (after perspective projection conversion) (position coordinates of vertex of the display object, texture coordinates, color data (luminance data), normal vector, α value, etc.) is stored in the main storage unit 172. Saved.

  Texture mapping is a process for mapping a texture (texel value) stored in the storage unit 170 to a display object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the storage unit 170 using texture coordinates or the like set (given) at the vertex of the display object. Then, a texture that is a two-dimensional image is mapped to a display object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing can be performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which Z values (depth information) of drawing pixels are stored. . That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer is referred to. Then, the Z value of the referenced Z buffer is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is a Z value (for example, a small Z value) on the near side when viewed from the virtual camera. In some cases, the drawing process of the drawing pixel is performed and the Z value of the Z buffer is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value). For example, in normal α blending, a process for obtaining a color obtained by combining two colors by performing linear interpolation with the α value as the strength of synthesis is performed.

  The α value is information that can be stored in association with each pixel (texel, dot), and is, for example, plus alpha information other than color information indicating the luminance of each RGB color component. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the image generation system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play. Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated by distributed processing using a plurality of terminals (game machine, mobile phone).

2. Method of this embodiment In this embodiment, when a slip stream area set behind the mobile body is generated and the traveling performance of the mobile body staying in the slip stream area is changed, the mobile body stays. A technique is adopted in which the effect magnification coefficient for changing the running performance is changed depending on whether or not the slip stream area is a slip stream area set behind a mobile body belonging to the same group.

  First, in this embodiment, the slip stream area | region R is set behind the mobile body PC which drive | works the course C set to the game space. Specifically, as shown in FIG. 2, a local coordinate axis D along the traveling direction with respect to the course C and a local coordinate axis B orthogonal to the local coordinate axis D are set, and the moving object PC on the local coordinate axis D is set. Based on the position of the representative point A, a substantially rectangular slip stream region R is set on the course. For this reason, according to the method of this embodiment, as shown in FIG. 2, the slip stream area | region R can be changed and set along a course shape. When the slip stream region R is set, a rotation angle with respect to the local coordinate axis D is set according to the direction (attitude) of the moving body PC on the course C, and the slip stream region R is set in the direction according to the set rotation angle. Is set behind the moving object PC in the course C.

  Further, in the present embodiment, an effect magnification factor (> 1) that is multiplied by the amount of movement of the moving body that travels behind the moving body PC for each position in the slipstream region R is set. As shown in FIG. 2, in a specific region Rm of the slip stream region R, the effect magnification coefficient is set to be the maximum value (upper limit value).

  Next, a method for determining the positional relationship between moving bodies and a method for changing the running performance based on the determination result of the positional relationship will be described with reference to FIGS.

  In the present embodiment, the position of the moving body is determined using the representative point, and as shown in FIGS. 3 and 4, the moving body PC1 operated by the first player and the movement operated by the second player When the body PC2 is traveling on the course C, in the example shown in FIG. 3, the representative point of the moving body PC2 in the slip stream region R set based on the position of the representative point A1 of the moving body PC1. A2 exists. Therefore, in the example illustrated in FIG. 3, it is determined that the moving object PC2 stays in the slip stream region R set behind the moving object PC1.

  Here, in the present embodiment, the effect magnification coefficient is set so as to increase as the moving object PC2 stays at a position where the distance from the representative point A1 of the moving object PC1 is closer. In the specific region Rm, the effect magnification coefficient is set. Is fixed at the maximum value. That is, in the example shown in FIG. 3, the value of the effect magnification factor that increases the traveling performance of the moving object PC2 is set according to the distance between the representative point A1 of the moving object PC1 and the representative point A2 of the moving object PC2.

  Next, in the example shown in FIG. 4, the moving body PC2 traveling behind the moving body PC1 stays in a specific region Rm in the slipstream region R set behind the moving body PC1. That is, in the example shown in FIG. 4, the value of the effect magnification factor that increases the traveling performance of the mobile object PC2 is maximized regardless of the distance relationship between the representative point A1 of the mobile object PC1 and the representative point A2 of the mobile object PC2. Is set.

  As described above, in the present embodiment, the value of the effect magnification factor for increasing the traveling performance of the moving body PC2 is set according to the position of the moving body PC2 within the slipstream region R set behind the moving body PC1. However, whether or not the moving body PC1 and the moving body PC2 are in the same group is an important index for setting the effect magnification coefficient.

  More specifically, in this embodiment, when a player starts a game, a group to which a moving body that he / she operates belongs is selected, and two or more moving bodies form a group so that the group opposition Have a racing game. In this group competition game, as described above, the rank between the groups is determined using the time of the moving body operated by the player who has completed the last round of the course in the group (round time) as the group time. ing.

  Therefore, in the present embodiment, the slip stream area where the moving body stays is set behind the moving body belonging to the same group based on the group setting information for specifying the belonging group for each player set in advance at the start of the game. If it is determined that the slip stream area is determined, a method of setting the effect magnification coefficient higher than that in the case of staying in a slip stream area set behind a moving body of a different group is adopted. .

  In this way, for example, when the moving body PC1 operated by the first player and the moving body PC2 operated by the second player are in the same group, as shown in FIG. If the mobile body PC1 and the mobile body PC2 travel and move so as to stay alternately in the slipstream areas R1 and R2, the slipstream areas set behind the mobile bodies belonging to different groups are used. The racing game can be advantageously advanced while keeping the traveling performance of the mobile PC1 and PC2 higher than the case.

  Therefore, according to the method of the present embodiment, the advanced user moves his / her moving body forward of the beginner according to the position of the moving body of the beginner, and the beginner's moving body stays in the slipstream region. By operating so as to establish the relationship, the racing game can be advantageously advanced while improving the running performance of the moving body together with the beginner. For this reason, according to the method of the present embodiment, even when there are beginners who are unfamiliar with the operation, the players can fully enjoy the racing game in a group competition while actively cooperating with each other to enhance mutual cooperation. An operation interface environment that can be provided can be provided.

  Further, in the present embodiment, a method is adopted in which the maintenance period of the effect magnification coefficient that changes the traveling performance is changed according to the period during which the moving body stays in the slip stream region.

  Specifically, as shown in FIGS. 6A and 6B, when the moving object stays in the slipstream region in the period T1 from t1 to t2, the longer the period T1 is, the longer the movement is Control is performed so that the period T3 for maintaining the state in which the running performance is changed after the body moves out of the slipstream region is prolonged. In the present embodiment, in the period T3, calculation is performed to return to the original effect magnification factor (= 1) while decreasing the effect magnification factor that determines the running performance by a certain value.

  Further, in the present embodiment, the period during which the running performance is changed depending on whether or not the slip stream area where the moving body has stayed is a slip stream area set behind the moving body of the same group. The method of changing is adopted.

  Specifically, as shown in FIGS. 6A and 6C, when the moving object stays in the slipstream region in the period T1 from t1 to t2, even if the period T1 is the same, the movement When the slip stream area where the body stays is a slip stream area set behind the moving bodies of different groups, the period T3 is set as shown in FIG. In the case of the slip stream region set behind the period T3, the period T3 is set as shown in FIG. That is, according to the examples shown in FIGS. 6 (A) and 6 (C), when the slip stream area where the moving body stays is the slip stream area set behind the moving body of the same group, The period T3 for maintaining the state where the running performance is changed is controlled to be prolonged.

  As described above, according to the method of the present embodiment, the slip set behind the moving body in the same group is compared to the case where the moving body stays in the slip stream area set behind the moving body in a different group. In the case where the moving body stays in the stream area, the period T3 during which the traveling performance of the moving body is changed after moving outside the slip stream area is prolonged, so FIG. As shown in the figure, it is possible to actively utilize the linked play in which the moving bodies belonging to the same group alternately move to the slipstream areas set behind each other and improve the running performance with each other. It is possible to provide an operating interface environment that is not found in conventional racing games.

  Further, in the present embodiment, as shown in FIG. 2, since the specific region Rm in which the effect magnification coefficient is set to the maximum value is provided in the slip stream region R, the moving object stays in the specific region Rm. The traveling performance of the moving body is maintained as follows.

  Specifically, as shown in FIG. 6D, in addition to the period T1 (t1 to t4) in which the mobile body stays in the slipstream region R, the mobile body stays in a specific region Rm. When the period T2 (t2 to t3) is measured and the period T2 exceeds an arbitrary threshold value, the traveling performance changes even when the moving body moves outside the specific region Rm. The effect magnification factor to be maintained is fixed at the maximum value in the period T2. Then, in the period T2 in which the effect magnification coefficient is maintained at the maximum value, the maximum value is maintained even after the moving body goes out of the slipstream region R, and after the elapse of the period T2 (after t5), The effect magnification factor so as to return to the original effect magnification factor (= 1) in the period (t5 to t6) until the end of the period T3 set based on the period T1 in which the mobile body stays in the slipstream region R Is gradually subtracted.

3. Processing of the present embodiment Next, a processing example for realizing the method of the present embodiment will be described in detail with reference to FIGS.

  FIG. 7 is a flowchart showing the main process of the calculation process of the running performance using the slip stream region in the method of the present embodiment.

  First, slip stream target determination processing (SS target determination) is performed to determine whether or not a mobile object to be calculated is staying in the slip stream region (step S100). If the target is found as a result of the determination process in step S100 (Y in step S200), a slip stream effect calculation process (SS effect calculation) is performed to change the running performance based on staying in the slip stream region ( Step S300) If the target is not found (N in Step S200), it is determined that the target is out of the slip stream region, and therefore the slip stream gradually returns the driving performance to the original driving performance. A state end check process (SS end check) is performed (step S400).

  FIG. 8 is a flowchart showing details of the slip stream target determination process (SS target determination).

  First, it is determined whether or not the own speed (the speed of the moving object to be operated) is equal to or higher than a predetermined speed (step S101). If it is determined that the own speed is equal to or higher than the predetermined speed (step S101). (Y), it is determined whether or not the speed of the mobile object to be investigated is equal to or higher than a predetermined speed (step S102).

  When it is determined that the speed of the mobile object to be investigated is equal to or higher than the predetermined speed (Y in step S102), the relative distance between the mobile objects on the course coordinates (local coordinate axis D: see FIG. 2) is calculated ( Step S103).

  Next, it is determined whether or not the investigation target stays in the slipstream area (step S104). For example, when the representative point of the mobile object to be investigated exists in the slipstream area set on the course, and it is determined that the mobile object to be investigated stays in the slipstream area (Y in step S104), an effect magnification coefficient for changing the running performance related to the mobile object to be investigated is calculated based on the relative distance obtained in step S103 (step S105).

  Next, based on the setting information of the group selected prior to the start of the game, it is determined whether or not the mobile object to be investigated belongs to the same group as the mobile object to be operated (step S106). If the investigation target is the same group (Y in step S106), the pair SS flag is set to ON (step S107). On the other hand, if the investigation target is a different group (N in step S106), the process in step S107 is bypassed.

  Next, it is determined whether or not the effect magnification coefficient calculated in step S105 is the largest value so far (step S108). In other words, once the moving object stays in the slipstream area, the effect magnification coefficient is obtained in the positional relationship with the moving object in front, but the traveling performance is calculated with the effect magnification coefficient calculated when the moving object is closest. To change. When the effect magnification coefficient is the maximum value thus far (Y in step S108), various setting information such as the effect magnification coefficient to be investigated and the pair SS flag are stored (step S109).

  Next, it is determined whether or not the survey of all the objects (all mobile objects traveling on the course) has been completed (step S110). If the survey has not been completed (N in step S110). Then, the investigation target is changed (step S111), and the processing from step S102 to S109 is performed. On the other hand, when all the objects have been investigated (Y in step S110), the process returns to the main process and the processes after step S200 shown in FIG. 7 are performed.

  FIG. 9 is a flowchart showing details of slip stream effect calculation processing (SS effect calculation).

  First, the effect magnification factor of the moving body is updated to the value obtained in the slip stream target determination process (SS target determination) shown in FIG. 8 (step S301), and the period T1 stayed in the slip stream region is updated (step S301). In step S302, the slipstream effect right acquisition state ST1, which is status data indicating the state of the moving body, is changed to “counting” (step S303).

  Next, referring to the MAX effect magnification right acquisition state ST2 which is status data indicating whether or not the effect magnification coefficient of the mobile body is fixed to the upper limit value, processing according to the state of ST2 is executed (step S304). .

  First, when ST2 is “not acquired” (“not acquired” in step S304), it is determined whether or not the position of the moving body is within the effect magnification MAX area (the specific area Rm shown in FIG. 2). Judgment is made (step S305).

  If the position of the moving object is within the effect magnification MAX area (Y in step S305), the period T2 during which the moving object stays in the effect magnification MAX area is updated (step S306), and the updated period T2 is updated. If the value is equal to or greater than the threshold value (Y in step S307), ST2 is changed to “Right acquisition” and the process returns to the main process (step S308).

  On the other hand, if the position of the moving body is not within the effect magnification MAX region (N in step S305), the value of the period T2 is reset to an initial value (for example, 0) and the process returns to the main process (step S309). .

  If the result of referring to the MAX effect magnification right acquisition state ST2 in step S304 is that "right acquisition is in progress" in ST2 ("right acquisition is in step S304"), the position of the moving object is the effect magnification MAX area. It is judged whether it is in (step S310).

  If the position of the moving body is within the effect magnification MAX area (Y in step S310), the value of the period T2 is updated and the process returns to the main process (step S311).

  On the other hand, if the position of the moving object is not within the effect magnification MAX area (N in step S310), the countdown of the period T2 is started (step S312), and ST2 is changed to “exercising rights” to perform main processing. (Step S313). That is, in step S312 and subsequent steps, processing for maintaining the effect factor coefficient of the moving object at the upper limit value in the period T2 is started.

  If ST2 is “exercising rights” as a result of referring to the MAX effect magnification right acquisition state ST2 in step S304 (“exercising rights” in step S304), the period T2 is counted down (step S314). ), It is determined whether or not the period T2 has ended (T2 ≦ 0) (step S315). If it is determined in step S315 that the period T2 has expired (Y in step S315), ST2 is changed to “unacquired” and the process returns to the main process (step S316).

  FIG. 10 is a flowchart showing details of the slip stream state end check process (SS end check).

  First, when ST2 is not “not yet acquired” (Y in step S401), ST2 is changed to “exercising rights” (step S402), and the countdown of period T2 is started (step S403). That is, when the SS end check is executed, since the target mobile body has already moved out of the slipstream area, it can be determined that it is out of the effect magnification MAX area, so the state of ST2 is changed. At the same time, it is necessary to start counting the period T2.

  When the period T2 ends (T2 ≦ 0) (Y in step S404), ST2 is changed to “unacquired”, and the state of ST1 is determined with reference to ST1 (step S406). If ST2 is “not yet acquired” (Y in step S401), the processing in steps S402 to S405 is bypassed.

  First, if ST1 is “not acquired” (“not acquired” in step S406), it is determined whether or not the value of the period T1 during which the mobile body stays in the slipstream region is equal to or greater than a threshold value. (Step S407). If the value of the period T1 is equal to or greater than the threshold value (Y in step S407), the value of the period T3 for maintaining the effect magnification coefficient is calculated based on the value of the period T1 (step S408). In step S408, the period T3 is calculated to be longer as the period T1 is longer. If the pair SS flag is on (Y in step S409), the period T3 is recalculated with the pair calculation formula (step S410), and the pair SS flag is reset to off (step S411). In step S410, based on the fact that the pair SS flag is on, it has been confirmed that the user has stayed in the slipstream area set behind the mobile body of the same group. Recalculation is performed using a calculation formula that makes the period T3 longer than when staying in the slipstream region set rearward. If the pair SS flag is off (N in step S409), the processes in steps S410 to S411 are bypassed. Finally, ST1 is changed to “exercising rights” and the process returns to the main process (step S412).

  On the other hand, if the period T1 is below the threshold value (N in step S407), the data of the effect magnification factor and the periods T1 and ST1 are reset to the initial values and the process returns to the main process (step S413).

  If ST1 is “exercising rights” as a result of referring to ST1 in step S406 (“exercising rights” in step S406), the period T3 obtained in step S408 or step S410 is counted down. (Step S414). When the period T3 ends (T3 ≦ 0) (Y in step S415), ST1 is changed to “decreasing effect magnification” and the process returns to the main process (step S416).

  If ST1 is “decreasing effect magnification” as a result of referring to ST1 in step S406 (“effect magnification decreasing” in step S406), a fixed value is subtracted from the value of the effect magnification coefficient (step S406). S417). When the effect magnification coefficient becomes equal to or less than 1 (= 1) (Y in step S418), the effect magnification coefficient and the period T3 are reset to initial values (step S419), and ST1 is set to “not yet acquired”. It changes and returns to the main process (step S420).
