  The accepting unit 110 accepts the determination area setting information output from the input unit 160 (C button). The determination area setting information is information for setting the determination area B (magnetic force range).

  In addition to the player character (an example of a moving object) and a magnet object, the object space setting unit 111 includes various objects (polygons, free objects) representing display objects such as buildings, stadiums, cars, trees, pillars, walls, and maps (terrain). A process of arranging and setting an object (an object composed of a primitive such as a curved surface or a subdivision surface) in the object space is performed.

  Here, the object space is a virtual space and includes both a two-dimensional space and a three-dimensional space. The two-dimensional space is a space in which an object is arranged at, for example, two-dimensional coordinates (X, Y), and the three-dimensional space is a space in which an object is arranged at, for example, three-dimensional coordinates (X, Y, Z). is there. For example, the object space setting unit 111 places an object in the world coordinate system when the object space is a three-dimensional space. In addition, for example, the position and rotation angle of the object in the world coordinate system (synonymous with the direction and direction, for example, when turning clockwise when viewed from the positive direction of the X, Y, and Z axes in the world coordinate system. Is determined, and an object is arranged at the position (X, Y, Z) at the rotation angle (rotation angle about the X, Y, Z axes).

  In particular, the object space setting unit 111 according to the present embodiment performs processing for setting a given object (magnet object) in the object space.

  The movement / motion processing unit 112 performs processing for moving an object in the object space. That is, based on input data input by the player through the input unit 160, a program (movement / motion algorithm), various data (motion data), etc., the object is moved in the object space, or the object is moved (motion, animation). ) Process. Specifically, object movement information (movement parameters such as position, rotation angle, movement speed, acceleration, movement amount, movement direction) and operation information (positions or rotation angles of parts constituting the object) are set to 1 A process of sequentially obtaining each frame (for example, 1/60 second) is performed. Note that a frame is a unit of time for performing object movement / motion processing and image generation processing.

  In particular, the movement processing unit 112a of the present embodiment performs a process of moving a moving object in the object space. Specifically, a process of moving the moving body is performed based on the movement input information of the player. Note that the movement processing unit 112a of the present embodiment moves the moving body so as not to exceed a predetermined speed V when moving the moving body based on the movement input information of the player.

  Further, the movement processing unit 112a performs a process of moving the determination region B (magnetic force range) based on a computer program.

  In addition, the movement processing unit 112a performs a process of moving the moving object based on the moving parameter of the moving object determined by the combination of the attribute of the moving object and the attribute of the determination area.

  Further, when there are a plurality of attribute types, the movement processing unit 112a varies the moving process of the moving object according to the combination type of the attribute of the moving object and the attribute of the determination area. For example, if there are attributes K1, K2, and K3, and the combination of the attribute of the moving object and the attribute of the determination area is expressed as (attribute of the moving object, attribute of the determination area), the combination of (K1, K1) is , (K2, K2) may be larger than the combination of (K2, K2). In addition, for example, the combination of (K1, K2) moves the moving body by attracting, the combination of (K1, K3) moves by moving the moving body, and the combination of (K2, K3) is The movement of the moving body may be forcibly stopped.

  Further, the movement processing unit 112a may move the moving body according to the relationship between the three strokes when there are the attributes K1, K2, and K3. For example, the combination of (K1, K2), the combination of (K2, K3), and the combination of (K3, K1) are the combination of (K2, K1), the combination of (K3, K2), and the combination of (K1, K3) Alternatively, the amount of change in the movement parameter of the moving body may be larger.

  Further, the movement processing unit 112a performs a process of changing the movement parameter of the moving object when the positional relationship between the moving object and the determination region satisfies a predetermined condition. More specifically, the movement processing unit 112a performs a process of changing the movement parameter of the moving object according to the distance between the moving object and the reference point of the determination area.

  In addition, the movement processing unit 112a performs a process of moving the determination area based on the movement parameter of the determination area determined by the combination of the attribute of the moving object and the attribute of the determination area.

  For example, when there are a plurality of attribute types, the movement processing unit 112a moves the determination area according to the combination type of the attribute of the moving object and the attribute of the determination area by the same method as the movement process of the moving object. The processing may be different.

  In addition, the movement processing unit 112a performs a process of changing the movement parameter of the determination region when the positional relationship between the moving object and the determination region satisfies a predetermined condition. More specifically, the movement processing unit 112a performs a process of changing the movement parameter of the determination region according to the distance between the moving object and the reference point of the determination region.

  In particular, the movement processing unit 112a according to the present embodiment performs a process of moving the moving body using repulsive force (repulsive force) when the attributes of the moving body and the attributes of the determination region are the same. In addition, the movement processing unit 112a performs a process of moving the moving body by applying an attractive force when the attribute of the moving body and the attribute of the determination region are different.

  Here, the determination area indicates an area set based on the reference point BO set in association with the position of the magnet object (the reference point MO of the magnet object). For example, the determination area indicates an area within a radius R centered on the reference point BO. Further, the attribute indicates each element among a plurality of elements having a correspondence relationship with each other. That is, one element (N pole) or the other element (S pole) of two elements (for example, N pole and S pole) having a corresponding relationship can be used as an attribute. In addition, each element of three elements (for example, K1, K2, and K3) that have a corresponding relationship (for example, a three-way relationship) can be used as an attribute.

  For example, when the player character is N pole and the magnet object is S pole, or when the player character is S pole and the magnet object is N pole, the movement processing unit 112a is between the player character and the magnet object. It is determined that an attractive force is to be generated, and an attractive force F1 to be applied to the player character is obtained. Based on the movement vector Va based on the attractive force F1, a player character movement vector VP (an example of a player character movement parameter) is obtained. Further, an attractive force F1 ′ (F1 ′ facing in the opposite direction to F1) to be applied to the magnet object is obtained. Based on the movement vector Vc based on the attractive force F1 ′, a movement vector VM of the magnet object (an example of a movement parameter of the magnet object) is obtained.

  In addition, the movement processing unit 112a, when the player character is the north pole and the magnet object is the north pole, or when the player character is the south pole and the magnet object is the south pole, It is determined that a repulsive force is generated during the time period, and a repulsive force F2 that is applied to the player character is obtained. Then, based on the movement vector Va based on the repulsive force F2, the movement vector VP of the player character is obtained. Further, a repulsive force F2 ′ (F2 ′ facing in the opposite direction to F2) acting on the magnet object is obtained. Then, based on the movement vector Vc based on the repulsive force F2 ′, the movement vector VM of the magnet object is obtained.

  When the movement processing unit 112a of this embodiment receives movement input information, the movement vector Vb of the player character corresponding to the movement input information and the movement vector Va associated with the magnetic force F (repulsive force or attractive force) are obtained. The player character is moved based on the combined vector VP.

  Further, the movement processing unit 112a changes the movement parameter according to the distance between the moving object and the reference point of the determination area. For example, as the distance between the player character and the magnet object is longer, the magnitude of the movement vector Va based on the magnetic force F (repulsive force or attractive force) is decreased. On the other hand, as the distance between the player character and the magnet object is shorter, the magnitude of the movement vector Va based on the magnetic force F (repulsive force or attractive force) is increased.

  Note that the movement processing unit 112a may move the moving body based on the moving parameter of the moving body determined by the combination of the attributes of each of the plurality of parts and the attribute of the determination region.

  Note that the movement processing unit 112a of the present embodiment moves the moving object and the magnet object in consideration of other forces such as gravity, frictional force, and air resistance in the game space.

  In addition, the first attribute setting unit 113 performs processing for setting the attribute of the moving object. For example, the first attribute setting unit 113 performs a process of setting one element (N pole) or the other element (S pole) among a plurality of elements having a corresponding relationship as the attribute of the moving object. .

  The first attribute setting unit 113 performs a process of switching (changing) the attribute of the moving object based on the player switching input information. For example, when receiving the player switching input information, the first attribute setting unit 113 performs a process of switching the magnetic pole of the player character from the S pole to the N pole (or from the N pole to the S pole).

  In addition, the 1st attribute setting part 113 performs the process which sets an attribute to each some site | part of a moving body, and performs the process which switches the attribute of each some site | part based on switching input information. In such a case, the first attribute setting unit 113 may simultaneously switch the attributes of the plurality of parts based on the switching input information, or may switch each part individually.

  Note that the first attribute setting unit 113 may switch attributes based on a computer program, regardless of player switching input information.

  In addition, the second attribute setting unit 114 performs processing for setting the attribute of the determination area. For example, the second attribute setting unit 114 performs a process of setting one element (N pole) or the other element (S pole) among a plurality of elements having a corresponding relationship as attributes of the determination region. . The second attribute setting unit 114 performs a process of switching (changing) the attribute of the determination area based on the player switching input information.

  Note that the second attribute setting unit 113 may switch the attribute of the determination area based on the computer program without depending on the player switching input information.

  The determination area processing unit 115 performs a process of changing at least one of the size and shape of the determination area.

  The game calculation unit 116 performs various game calculation processes. For example, a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for determining whether or not a clear condition for each game stage is satisfied, or a game when a game end condition is satisfied There is a process for ending the process, and a process for advancing the ending when the final stage is cleared.

  The game calculation unit 116 according to the present embodiment determines whether or not the player character has reached the goal point, and makes a game determination based on whether or not the height of the player character is a predetermined value (for example, Y = 0) or more. I have to. For example, when the player character has not reached the goal point within the time limit, it is determined that the game is over, or when the height of the player character is not equal to or greater than a predetermined value, it is determined that the game is over.

  In addition, the game calculation unit 116 performs a hit determination for determining whether or not the hit area of the player character and the hit area of the enemy character have been hit, and performs a process of subtracting a parameter (physical strength value or the like) of the player character.

  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. The image generated by the drawing unit 120 may be a so-called two-dimensional image or a so-called three-dimensional image.

  When a two-dimensional image is generated, an image viewed from the side is generated. For example, a priority is set for each object (sprite), and rendering is performed in order from an object having a lower priority. When objects overlap, an object with a high priority is drawn on an object with a low priority.

When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model) ) Is input, and vertex processing (shading by a vertex shader) is performed based on the vertex data included in the input 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 the vertex processing, according to the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate transformation, for example, world coordinate transformation, visual field transformation (camera coordinate transformation), clipping processing, perspective transformation (projection transformation) ), Geometry processing such as viewport conversion is performed, and based on the processing result, the vertex data given to the vertex group constituting the object is changed (updated or adjusted).

  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 (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed. In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to the drawing buffer 174 (a buffer capable of storing 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) 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.

  Note that the drawing unit 120 performs a virtual camera (viewpoint) control process for generating an image that can be seen from a given (arbitrary) viewpoint in the object space. Specifically, when generating a three-dimensional image, the virtual camera position (X, Y, Z) or rotation angle (for example, from the positive direction of each of the X, Y, and Z axes) in the world coordinate system is used. (Rotation angle when turning clockwise) is controlled. In short, processing for controlling the viewpoint position, the line-of-sight direction, and the angle of view is performed. The drawing unit 120 may rotate the virtual camera at a predetermined rotation angle. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position 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.

  For example, when an object (for example, a player character) is photographed from behind using a virtual camera, the position of the virtual camera and the orientation of the virtual camera are controlled so that the virtual camera follows changes in the position and orientation of the object. In this case, the virtual camera can be controlled based on information such as the position, orientation, or speed of the object obtained by the movement / motion processing unit 112. Alternatively, the virtual camera may be set in a predetermined direction or may be controlled to move along a predetermined movement route. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or orientation of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  The vertex processing and pixel processing 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). Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of drawing processing is high, and expressive power is greatly improved compared to conventional hardware-based fixed drawing processing. Can do.

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

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the object data storage unit 176. Is done.

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit 178 of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit 178 of the storage unit 170 using the texture coordinates set (given) at the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an 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 by a Z buffer method (depth comparison method, Z test) using a Z buffer 179 (depth buffer) in which a Z value (depth information) of a drawing pixel is stored may be performed. it can. That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer 179 is referred to. Then, the Z value of the referenced Z buffer 179 is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is the front side when viewed from the virtual camera (for example, a small Z value). If it is, the drawing process of the drawing pixel is performed and the Z value of the Z buffer 179 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).

  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 game 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, distributed processing may be performed using a plurality of terminals (game system, mobile phone).

2. Method of this Embodiment (1) Outline As shown in FIG. 2, the game system of this embodiment moves a player character P (an example of a moving object) from a start point (start point) in an object space (virtual two-dimensional space). Process to move to the goal point (end point). For example, in the present embodiment, processing for moving the player character P is performed based on the movement input information of the player.

  In the present embodiment, a plurality of magnet objects M each having a magnetic pole (N pole or S pole) set in advance in the object space are arranged. For example, as shown in FIG. 2, there are a magnet object M in which the N pole is set, a magnet object M in which the S pole is set, and the like. In the object space, there is also a magnet object that moves based on a given movement vector, such as an elastic magnet object M ′.

  In the present embodiment, the player character P is also set with N or S poles. In the example of FIG. 2, the player character P has an N pole.

  In this embodiment, the magnetic force F is obtained based on the magnetic pole of the player character P and the magnetic object M, and the movement vector VP (an example of a movement parameter) of the player character P is obtained based on the magnetic force F. Then, a process of moving the player character P based on the obtained movement vector VP is performed.

  For example, when the magnetic pole of the player character P and the magnetic object M are different from each other, the attractive force F1 at which the player character P and the magnetic object attract each other is obtained, and the magnetic pole of the player character P and the magnetic object M are obtained. In the same case, the repulsive force F2 at which the player character P and the magnet object are generated is obtained. Then, the movement vector Va of the player character based on the obtained attractive force F1 or repulsive force F2 is obtained. Then, the movement vector Va is reflected in the movement process of the player character P.

  Further, in the present embodiment, processing for switching the magnetic pole of the player character P from the N pole to the S pole or from the S pole to the N pole is performed based on the magnetic pole switching input information (switching input information) of the player. Therefore, when the player character P and the magnet object are attracted by the attractive force F1, when the magnetic pole of the player character P is switched based on the magnetic force switching input information, the player character P immediately opens the magnet object M. Can be moved. Thus, in this embodiment, the player character P can be moved using magnetic force, and an interesting game can be realized.

  In the present embodiment, gravity (force in the negative Y-axis direction) is applied to the player character P. When the position (X, Y) of the player character P falls below a predetermined value (Y = 0), a game over determination process is performed to end the game. Therefore, for example, in the absence of a floor object, in order to prevent the player character P from falling, the player performs an operation to move the player character P to the ceiling using the magnetic force of the magnet object M. Become.

  In the present embodiment, the process is performed to prevent the player character from falling by setting the magnitude of the magnetic force F (attractive force F1, repulsive force F2) to be larger than the gravity G. For example, when the magnet object M placed on the wall or ceiling and the player character P are in contact with each other by the attractive force F1, the player character P has a force that cancels the gravity G (the magnitude is the same as the gravity G). , The force in the Y-axis plus direction) is applied to perform the process of invalidating the gravity.

  In this embodiment, the S pole and the N pole are displayed in different colors. For example, display processing is performed so that the player can easily recognize the magnetic poles of the player character P and the magnet object M by displaying the south pole in blue and the north pole in red.

(2) Description of Movement Process Based on Magnetic Force In this embodiment, the process of moving the player character P is performed based on the movement vector Vb determined by the player's movement input information. In the (magnetic force range), the movement vector Va accompanying the magnetic force F is reflected on the player character P, and the player character is moved.

  For example, in the present embodiment, as shown in FIGS. 3A and 3B, a determination region B having a radius R centered on a reference point BO set in association with the position of each magnet object is set. When the player character P is located in the region B, a process for applying a magnetic force F to the player character P is performed.

  More specifically, as shown in FIG. 3A, when the player character P is not located in the determination region B, the player character P is not affected by the magnetic force F by the magnet object M. Then, the movement process is performed based on the movement vector Vb based on the movement input information of the player.

  On the other hand, as shown in FIG. 3B, when the player character P is located in the determination region B, the player character P is affected by the magnetic force F by the magnet object M. According to the example of FIG. 3B, since the magnetic poles of the player character P and the magnet object M are different from each other, a process of moving the player character P by the movement vector Va based on the attractive force F1 is performed. That is, the direction of the attractive force F1 is set in the direction from the reference point PO of the player character P to the reference point BO of the determination area B, the magnitude of the attractive force F1 that approaches the reference point BO from the reference point PO is obtained, and based on the attractive force F1. A movement vector Va is obtained. For example, the direction of the movement vector Va is set to the direction of the attractive force F1, and the movement amount of the movement vector Va is obtained based on the magnitude of the attractive force F1. Then, a process of moving the player character P is performed based on the movement vector Va.

  In the present embodiment, when the player character P is located in the determination region B and the movement input information is received, the movement vector Va associated with the attractive force F1 and the movement vector Vb based on the movement input information are obtained. The player character P is moved based on the combined vector VP. When the reference point PO and the reference point BO are at the same position, the player character P cannot move based on the movement input information.

  Also, with reference to FIGS. 4A and 4B, the case where the magnetic poles of the player character P and the magnet object M have the same relationship will be described. As shown in FIG. If the player character P is not located within the determination area B set to M, the player character P is not affected by the magnetic force F of the magnet object M.

  On the other hand, as shown in FIG. 4B, when the player character P is located in the determination area B and the magnetic poles of the player character P and the magnet object M have the same relationship, A movement vector Va based on the repulsive force F2 is obtained, and a process of moving the player character P based on the movement vector Va is performed. That is, the direction of the repulsive force F2 is set in the direction from the reference point BO to the reference point PO, and the magnitude of the repulsive force F2 is obtained. Then, the movement vector Va is obtained based on the repulsive force F2. The direction of the movement vector Va is set to the direction of the repulsive force F2, and the amount of movement of the movement vector Va is obtained based on the magnitude of the repulsive force F2. Then, a process of moving the player character P is performed based on the movement vector Va.

In the present embodiment, when the repulsive force F2 is applied to the player character P, a value obtained by inversely proportional to the square of the distance x between the reference point PO of the player character P and the reference point BO of the determination area B is set to the repulsive force F2. Calculate as size. Further, the magnitude of the repulsive force F2 may be determined by the parameter a. For example, if the parameter a is made different for each determination area, a plurality of determination areas having different repulsive forces F2 can be set. That is, as shown in FIG. 5, to the magnitude y the relationship y = a / ^{x 2} of repulsion F2. In this embodiment, when the distance x ≦ x1 between the reference point PO of the player character P and the reference point BO of the determination area B, the magnitude y of the repulsive force F2 is set to a predetermined amount y1. This is to prevent the movement amount of the player character P from becoming extremely large.

  Further, in the present embodiment, when the player character P is located in the determination region B and the movement input information is received, the movement vector Va associated with the repulsive force F2 and the movement vector Vb based on the movement input information. The player character P is moved based on a vector VP obtained by combining (movement direction / movement amount).

  In the present embodiment, whether or not the player character P is located in the determination area B is determined based on whether or not the hit area predetermined for the player character P and the determination area B are hit (crossed). Or not). For example, when it is determined that the hit area set for the player character P and the determination area B are hit, it is determined that the player character P is located in the determination area B.

(3) Movement process associated with switching of magnetic poles In the present embodiment, a process of switching the magnetic poles of the player character P will be described. For example, as shown in FIG. 6A, if the magnetic pole of the player character P is N-pole and the magnetic pole of the magnet object M is S-pole, the player character P is attracted to the magnet object M, and the player character P The reference point PO of P and the reference point BO of the determination area B are close to each other. In this embodiment, when the player's magnetic pole switching input information is received in such a state, as shown in FIG. 6B, processing for switching the magnetic pole of the player character P from N pole to S pole is performed. In this embodiment, when it is determined that the magnetic pole of the player character P and the magnetic object M are the same, the player character P is moved by applying the repulsive force F2.

  For example, as shown in FIG. 6C, when the distance x between the reference point PO of the player character P and the reference point BO of the determination area B is short (x <x2 <R), the player character P is powerful. The repulsive force F2 works, and for example, a process of moving the player character P so as to jump greatly beyond the determination region B is performed. More specifically, the magnetic pole of the player character P and the magnetic pole of the magnet object M are a combination of different polarities, and the reference point PO and the reference point BO are close to each other (x <x2 <R). When the magnetic pole switching input information is received without receiving the information, the player character jumps based on a predetermined movement vector Va (a movement vector in which the maximum amount of movement with the magnetic force F is set in the upward direction). Let

  Further, in the present embodiment, an example of movement processing in the height direction (Y-axis direction) using magnetic pole switching will be described with reference to FIGS. First, as shown in FIG. 7A, when movement input information related to a player jump is received when the player character P is not located in the determination region B, in this embodiment, the player character P is moved to the movement vector Vb. Based on the above, a movement process for jumping at a height H0 is performed.

  On the other hand, as shown in FIG. 7B, the reference point PO of the player character P and the reference point BO of the determination area B are close to each other by combining the magnetic poles of the player character P and the magnetic object M with different polarities. Yes (x <x2 <R), and when the magnetic pole switching input information is received when the movement input information related to the jump is received, the magnetic pole of the player character P and the magnetic pole of the magnet object M become a combination of the same polarity, A movement process for jumping the player character P at H1 (H0 <H1, R <H1) higher than H0 is performed.

  That is, the magnetic pole of the player character P and the magnetic pole of the magnet object M are a combination of different polarities, the reference point PO and the reference point BO are close to each other (x <x2 <R), and movement input information related to jumping When the magnetic pole switching input information is received when the magnetic field switching is received, the direction of the movement vector Vb based on the movement input information is set as the direction of the movement vector VP, and the movement vector Vb and the movement vector Va based on magnetic force are synthesized. The movement vector VP is obtained by setting the magnitude of the vector as the magnitude (movement amount) of the movement vector VP. In this way, the player character P can be moved based on the movement vector VP larger than the movement vector Vb.

  As shown in FIG. 7C, the magnetic pole of the player character P and the magnetic pole of the magnet object M are different from each other, and the reference point PO of the player character P and the reference point BO of the determination area B are close to each other. In the case of (x <x1 <x2), when movement input information related to jumping from the player is received, movement restriction processing is performed so that jumping is not possible.

  Next, a process (dash process) for moving the player character P in the right direction (X-axis plus direction) at high speed using magnetic pole switching will be described with reference to FIGS.

  For example, as shown in FIG. 8A, when the player character P is located outside the determination area B, the movement vector Vb is used when the player character P is moved based on the player's movement input information. .

  In this embodiment, as shown in FIG. 8B, the player character P's magnetic pole and the magnet object M's magnetic poles are different in polarity from each other, and the player character P's reference point PO and the determination area B's reference point BO are combined. Are in a state close to (x <x2 <R), and when the magnetic pole switching input information is received when moving input information in the right direction (X-axis plus direction) of the player is received, the magnetic pole of the player character P And the magnetic pole of the magnet object M are a combination of the same poles, and the player character P is moved based on a movement vector VP (Va <VP) larger than the magnitude of the movement vector Vb.

  That is, the magnetic pole of the player character P and the magnetic pole of the magnet object M are a combination of different polarities, the reference point PO and the reference point BO are close to each other (x <x2 <R), and the rightward movement is performed. When the magnetic pole switching input information is received when the input information is received, the direction of the movement vector Vb based on the movement input information is set as the direction of the movement vector VP, and the movement vector Vb and the movement vector Va by the magnetic force are set. The movement vector VP is obtained by setting the size of the combined vector as the magnitude (movement amount) of the movement vector VP. In this way, the player character P can be moved based on the movement vector VP larger than the movement vector Vb.

  As described above, in the present embodiment, the player can move the player character P with a large amount of movement by inputting the movement input information in the right direction and switching the magnetic poles. In this way, it is possible to express a situation where the player character P moves around the magnet object M and moves at high speed.

  In the present embodiment, the magnetic pole of the player character P and the magnetic pole of the magnet object M are a combination of different polarities, the reference point PO and the reference point BO are close to each other (x <x2 <R), and When the magnetic pole switching input information is received when the movement input information in the right direction is received, the direction of the movement vector Vb based on the movement input information is set as the direction of the movement vector VP, and the magnitude of the movement vector Va. May be set as the magnitude (movement amount) of the movement vector VP.

  In the present embodiment, the player character P is moved beyond the predetermined speed V during the movement based on the movement vector VP. In such a case, when new movement input information in the advancing direction of the player character P is received, if the player character is to be moved based on the newly received movement input information, the movement speed of the player character is increased. It becomes too much.

  Therefore, in the present embodiment, while the player character P is being moved based on the movement vector VP, as long as the moving speed of the player character P exceeds the predetermined speed V, a new traveling direction of the player character P is newly established. Control not to accept movement input information. However, when movement input information in the direction opposite to the moving direction of the player character is received, the movement speed of the player character is decelerated based on the movement input information.

  Further, in the present embodiment, when the magnetic pole of the player character P and the magnetic object M are different and the positions of the reference point PO and the reference point BO are the same, the reference point of the player character is determined based on the movement input information of the player. When the magnetic pole switching input information is received in a state where the PO is virtually moved and the reference point PO is virtually moved (hereinafter referred to as “reference point PO ′”) and the reference point BO are separated from each other. Alternatively, the direction from the reference point BO to the reference point PO ′ may be set as the direction of the movement vector VP. In such a case, the movement amount of the movement vector VP is calculated based on the distance x ′ between the reference point PO ′ and the reference point BO.

  As shown in FIG. 8C, the magnetic pole of the player character P and the magnetic pole of the magnet object M are different from each other, and the reference point PO of the player character P and the reference point BO of the determination area B are close to each other. In the case of (x <x1 <x2), regardless of the player's movement input information, the movement direction of the movement vector VP is set in the direction from PO to BO, and the player character P moves so as to touch the magnet object M. A process for moving the player character P (movement restriction process) is performed by setting the amount of movement of the vector VP. When the magnitude of the movement vector Va based on the attractive force F1 is larger than the magnitude of the movement vector Vb based on the player's movement input information (Va> Vb), movement input information for moving the player character P is accepted. In this case, the movement of the player character P in the direction opposite to the direction of the attractive force F1 (movement vector Va) is restricted.

  In the present embodiment, the moving body may be moved in consideration of other forces such as gravity, frictional force, and air resistance in the game space. For example, a force such as gravity, friction force, and air resistance in the game space may be added to the movement vector VP.

(4) Setting of magnetic force invalid time In this embodiment, as shown in FIG. 9, when the S-pole magnet object M and the N-pole magnet object are alternately arranged in the object space, the player By continuously performing the magnetic pole switching input, the player character P can be continuously moved at a high speed.

  Here, in this embodiment, the player character P is smoothly moved by invalidating the magnetic force F (attractive force F1 and repulsive force F2) of the player character P for a certain period of time. For example, for a predetermined period (for example, 10 frames) immediately after the magnetic pole switching, the player character P invalidates the magnetic force F (attraction F1 and repulsive force F2) of the magnet object M and does not perform the movement process based on the magnetic force F. Yes. In this way, when the player's magnetic pole switching input is performed with good timing, the movement of the player character P becomes smooth.

  Specifically, as shown in FIG. 9, when the operation input is rightward and the magnetic pole of the player character P is switched to the same magnetic pole as that of the magnet object M1 at time T1, and the robot moves at high speed in the rightward direction. During the predetermined period T, the player character P is not moved by adding the movement vector Va accompanying the repulsive force F2 of the magnet object M1. In other words, the player character P is moved by the movement vector Va associated with the repulsive force F2 determined at the time point T1, for example, so that the player character P located at Q1 is not further affected by the repulsive force F2 in the determination region B. Perform the move process. When the predetermined period T elapses, the magnetic force F of the player character P is validated. When the player character P enters the determination area B of the magnet object M2, the movement vector Va associated with the attractive force F1 of the magnet object M2 is added. Then, the player character P is moved.

  Similarly, when the player character moves using the repulsive force F2 of the magnet objects M2 and M3, the player character P is moved to the magnet for a predetermined period T from the timing T2 and T3 when the magnetic pole of the player character P is switched. The movement vector Va accompanying the repulsive force F2 of the objects M2 and M3 is moved without being added. That is, the player character P is moved based on the movement vector Va associated with the repulsive force F2 determined at the times T2 and T3. In this way, a state in which the player character P is smoothly moved when the player inputs the magnetic pole switching in a timely manner while preventing the movement amount from being excessively added and cumulatively added is represented. Can do.

(5) Method for Moving Magnet Object Based on Magnetic Force In this embodiment, the elastic magnet object M ′ is also moved based on the magnetic force F.

  For example, as shown in FIG. 10A, when the player character P is not located in the determination area B of the elastic magnet object M ′, the elastic magnet object M ′ is determined by a predetermined movement vector VM1. Processing to move.

  As shown in FIG. 10B, when the player character P is positioned in the determination area B of the elastic magnet object M ′ and the player character P and the elastic magnet object M ′ have different polarities. Performs a process of moving not only the player character P but also the elastic magnet object M ′ by the attractive force F1 ′. For example, a process of moving the bullet magnet object M ′ from the reference point BO set in association with the position of the bullet magnet object M ′ based on the movement vector VM2 toward the reference point PO of the player character P is performed.

  Then, based on the magnetic pole switching input information of the player, as shown in FIG. 10C, when the player character P is positioned in the determination area B of the elastic magnet object M ′, the player character P and the elastic magnet object M When ′ has the same polarity, not only the player character P but also the elastic magnet object M ′ is moved by the repulsive force F2 ′. For example, a process of moving the elastic magnet object M ′ by the movement vector VM3 that faces the direction from the BO to the direction opposite to the direction of the PO is performed.

  In the present embodiment, the magnitudes of the movement vectors VM2 and VM3 are set to be the same as the magnitude of the VM1 and the directions of the movement vectors VM2 and VM3 are controlled. However, the movement vector obtained by combining the movement vectors VM1 and VM2 is used. Alternatively, the elastic magnet object M ′ may be moved based on the movement vector obtained by combining the movement vectors VM1 and VM3. Further, when the player character P and the bullet magnet object M ′ are hit with different polarities, the game calculation may be performed so that the player character P is damaged.

3. Flowchart The flow of the movement process based on the magnetic force F of this embodiment will be described with reference to FIG. Note that x1, x2, and R shown in the steps of FIG. 11 have a relationship of 0 ≦ x1 <x2 <R as shown in FIG. X indicates the distance between the reference point PO of the player character P and the reference point BO of the determination area B.

  First, it is determined whether or not a frame update has arrived (step S1). If it is determined that the frame is to be updated (Y in step S1), it is determined whether or not the movement process based on the magnetic force F of the player character P is set to be effective (step S2). If the movement process based on the magnetic force F of the player character P is set to be valid (Y in step S2), it is determined whether x <R. If it is determined that x <R, it is further determined whether or not x <x2 (step S4).

  On the other hand, if the movement process based on the magnetic force F of the player character P is set to be invalid (N in step S2), and if x <R is not satisfied (N in step S3), the process is terminated.

  If it is determined that x <x2 (Y in step S4), it is determined whether or not the player character P and the magnet object M have the same polarity (step S5).

When it is determined that the player character P and the magnet object M have the same polarity (Y in Step S5), it is determined whether or not the magnetic pole of the player character P has been switched immediately before (in the immediately preceding frame) (Step S6). ),
If the player character's magnetic pole is switched immediately before (Y in step S6), a movement process (step S7) associated with the magnetic pole switching is performed. For example, the process of moving the player character is performed based on the movement vector VP obtained by combining the movement vector Va associated with the repulsive force F2 and the movement vector Vb corresponding to the movement input information.

  Then, the movement process based on the magnetic force F of the player character P is set to be invalid for a predetermined period (for example, 30 frames) (step S8). On the other hand, when the magnetic pole of the player character has not been switched immediately before (N in Step S6), a process of moving the player character by using the repulsive force F2 is performed (Step S9).

  If it is determined that the player character P and the magnet object M are not of the same polarity (N in step S5), a process of determining whether x <x1 is performed (step S10). If it is determined that x <x1 (Y in step S10), a movement restriction process for the player character P is performed (step S11). For example, regardless of the player's movement input information, the movement vector Va is obtained according to the direction of the magnetic force F from the player character reference point PO toward the reference point BO of the determination area B, and the movement of the player character P is performed based on the movement vector Va. The moving direction of the vector VP is set, the moving amount of the moving vector VP is set so that the player character P touches the magnet object M, and the player character P is moved. On the other hand, if x <x1 is not satisfied (N in step S10), a process of moving the player character using the attractive force F1 is performed.

  If it is determined that x <x2 is not satisfied (N in step S4), it is determined whether or not the player character P and the magnet object have the same polarity (step S13). If it is determined that the player character P and the magnet object have the same polarity (Y in step S13), a process of moving the player character using the repulsive force F2 is performed (step S14). On the other hand, when it is determined that the player character P and the magnet object have different polarities (N in step S13), a process of moving the player character using the attractive force F1 is performed (step S14). The process ends here.

4). Application Examples (1) Application Example of Processing for Moving Magnet Object M Based on Magnetic Force In this embodiment, the player object P is moved based on the magnetic force F without moving the player character P based on the magnetic force F. You may do it. For example, as shown in FIG. 13A, when the magnetic pole of the player character P is the N pole and the magnetic pole of the magnet object M is the S pole, the magnet object M is moved without moving the player character P. A process of moving based on the movement vector Va accompanying the magnetic force F (attraction F1) is performed. When the magnetic pole switching input information of the player is received, the magnetic pole of the player character P is switched from the N pole to the S pole, and the magnet object is moved without moving the player character P as shown in FIG. A process of moving M based on the movement vector Va accompanying the repulsive force F2 is performed.

  For example, as shown in FIG. 13B, the player character P pulls the magnet object M and switches the magnetic pole of the player character P, thereby causing the magnet object M to repel. In such a case, when the magnet object M hits the enemy character E, the game calculation may be performed so as to damage the enemy character E.

(2) Method of switching the magnetic poles of the magnet object M In this embodiment, the present invention may be applied to a game for switching the magnetic poles of the magnet object M set in the object space instead of the player character P. For example, as shown in FIG. 14, the player character P should not come into contact with the enemy character E in an object space where the player character P with the N pole set in advance and the enemy character E with the S pole set in advance exist. On the other hand, the process of moving the player character P from the start point to the goal point based on the movement vector Va associated with the magnetic force F of the magnet object M is performed regardless of the player's movement input information.

  In such a case, for each of the plurality of magnet objects M, the magnetic pole switching input information from the player is received and the magnetic object M is switched. In this way, the player can indirectly move the player character P using the magnetic force F of the magnet object M, so that the game can be played with more fun.

(3) Change of determination area In this embodiment, the determination area B is set as a circle with a radius R centered on the reference point BO. However, the size and shape of the determination area B may be changed. Good. For example, the radius of the determination region B may be changed to x1, x2, and R (0 ≦ x1 <x2 <R) in a cycle of 3 seconds. The determination area B may be a polygon or a rectangle instead of a circle. The determination area B may be set based on input information of the player.

(4) Object having a plurality of magnetic poles simultaneously In the present embodiment, the player character P may have a plurality of magnetic poles at the same time.

  For example, as shown in FIGS. 15A and 15B, an object in which the upper half of the player character P is set to the S pole (or N pole) and the lower half of the player character P is set to the N pole (or S pole) The object has two types of magnetic poles. Then, for example, based on the magnetic pole switching input information of the player, as shown in FIG. 15A, the player character P has its upper half from the S pole and the lower half from the N pole, and as shown in FIG. A process of switching the upper body of the character P to the N pole and the lower body to the S pole is performed.

  In this way, for example, when it is desired to move the player character P toward the S-pole magnet object on the ceiling, the operation of switching the magnetic pole is performed so that the upper body of the player character P becomes the N-pole. When it is desired to move the player character P toward the S-pole magnet object installed on the floor, it is possible to input to switch the magnetic pole so that the lower half of the player character P becomes the N-pole. Fine movement control is possible based on the movement vector Va based on.

  Further, as shown in FIGS. 15C and 15D, a process of setting different magnetic poles for the right hand part and the left hand part of the player character P and switching the magnetic poles of each part based on the magnetic pole switching input information of the player. You may go. For example, based on the magnetic pole switching input information of the player, as shown in FIG. 15C, the player character P shown in FIG. 15D is shown in FIG. 15D, with the right hand part RH of the player character P from the N pole and the left hand part LH from the S pole. The right hand part RH is switched to the S pole and the left hand part LH is switched to the N pole.

(5) Multiplayer game In the present embodiment, the player characters to be operated by a plurality of players may be arranged in a common object space. For example, the movement vector Va associated with the magnetic force F of each player character is obtained by the combination with the magnetic pole generated between the player characters, and the player movement vector VP reflecting the movement vector Va is obtained for each player character. The movement process may be performed based on the movement vector VP.

(6) Switching of magnetic poles Although the magnetic poles of the magnet object M of this embodiment are set as predetermined magnetic poles, the magnetic poles may be automatically switched based on a computer program.
