  Hereinafter, embodiments of the present invention will be described.

  First, an information processing apparatus 10 according to an embodiment of the present invention will be described with reference to FIG. The information processing apparatus 10 is, for example, a smartphone, a PC, a game device, or the like, and can execute a game application according to the present embodiment. The game application may be received from a predetermined application distribution server via the Internet, for example, or stored in advance in a storage device provided in the information processing apparatus 10 or a storage medium such as a memory card readable by the information processing apparatus 10. It may be stored.

  Here, an outline of the game according to the present embodiment will be described. The game according to the present embodiment is, for example, a role playing game or a simulation game, and is a game that moves a game medium on a field in the game.

  The game medium is electronic data used in the game, and includes any medium such as a card, an item, a character, an avatar, and an object. The game medium is electronic data that can be acquired, held, used, managed, exchanged, combined, strengthened, sold, discarded, and / or gifted by the user in the game. It is not limited to those specified in the specification.

  Hereinafter, unless otherwise specified, “game media owned by the user” refers to game media associated with the user ID of the user. Further, “giving a game medium to a user” indicates that the game medium is associated with a user ID. Further, “discarding the game media owned by the user” means that the association between the user ID and the game media is canceled. Further, “consuming a game medium owned by a user” indicates that some effect or influence can be generated in the game in accordance with the cancellation of the association between the user ID and the game medium. In addition, “sale of game media owned by the user” means that the association between the user ID and the game media is canceled and another game media (for example, virtual currency or item) is associated with the user ID. It shows that. “Transfer the game medium owned by user A to user B” means that the association between the user ID of user A and the game medium is canceled and the game medium is associated with the user ID of user B. Indicates.

  The game according to the present embodiment generally includes a first game part, a second game part, and a third game part.

  In the first game part, the user operates the user character to advance the game while searching for a field in the game. Specifically, the user character moves on the field in response to a user operation. There are various areas in the field, such as towns and dungeons, for example. Various events occur depending on the area, such as conversations with resident characters in the town and battles with enemy characters encountered in the dungeon. To do. As the event is executed, the main story of the game proceeds. In the first game part, for example, when a battle with an enemy character is won, a game medium such as an item, a virtual currency, or a character may be given to the user. The assigned game media can be used in, for example, a third game part to be described later.

  As will be described later, the field according to the present embodiment is provided with a passage through which the user character can move. Specifically, a plurality of passages (lateral passages) extending substantially parallel to one direction (for example, the left-right direction) on the screen and two lateral passages extending in other directions (for example, the vertical direction) on the screen. A plurality of passages (longitudinal passages) to be connected are provided. As will be described later, in this embodiment, the user character moves on the game field at a moving speed according to a predetermined user operation along the lateral passage. On the other hand, the user character moves along the vertical path on the game field by a predetermined distance, for example, a distance from one horizontal path to another horizontal path. As described above, in the present embodiment, the process of moving the user character is different between the case where the user character moves along the horizontal passage and the case where the user character moves along the vertical passage. Details of the process of moving the user character will be described later.

  In the second game part, the user collects various game media such as items, virtual currency, and characters. Specifically, when a user character is moved to a specific area such as a mining yard and a fishing pit provided on the field, or a game medium such as a specific character or object is selected (for example, a touch operation on the screen), the game A sub-event occurs that can be acquired by the medium. The sub-event includes, for example, the progress of the sub-story and the execution of the mini game, but the contents of the sub-event are not limited thereto. Various game media can be given to the user according to the execution result of the sub-event. The assigned game media can be used in, for example, a third game part to be described later.

  In the third game part, the user strengthens the user character, for example. Specifically, as described above, the game media assigned to the user in the first game barter and the second game part are consumed, so that various game parameters of the user character are changed. The game parameters include, for example, the user character level, HP, attack power, defense power, attributes, and skills, but are not limited thereto. The user character is strengthened according to the change in the game parameter of the user character. By strengthening the user character, the probability that the user character can win in the battle with the enemy character in the first game part is increased.

  Thus, in the game according to the present embodiment, the user repeatedly performs the first game part, the second game part, and the third game part.

  Next, each component of the information processing apparatus 10 will be described. The information processing apparatus 10 includes a storage unit 11, a display unit 12, and a control unit 13.

  The storage unit 11 is, for example, a storage device, and stores various information and programs necessary for game processing. For example, the storage unit 11 stores game applications.

  In addition, the storage unit 11 stores various images (texture images) for projection (texture mapping) onto various objects arranged in the three-dimensional virtual space.

  For example, the storage unit 11 stores an image of the user character. Hereinafter, the user character is referred to as a first game medium, and an object on which an image of the first game medium is projected is also referred to as a first object.

  Moreover, the memory | storage part 11 memorize | stores images, such as a building, a wall, a tree, or NPC (Non Player Character), for example. Hereinafter, a building, a wall, a tree, an NPC, or the like is referred to as a second game medium, and an object on which an image of the second game medium is projected is also referred to as a second object.

  The storage unit 11 stores a background image (background image) such as a sky or a distant view. The background image is projected onto a background object described later.

  The storage unit 11 stores an image (field image) of a field (for example, the ground). The field image is projected onto a field object described later. A field object onto which an image of the field is projected is used as a virtual field (ground) in the game.

  Here, for example, as shown in FIG. 2, a texture coordinate system having u and v axes orthogonal to each other is set in the field image. In the present embodiment, the field image includes a plurality of first areas 14 corresponding to a plurality of horizontal paths through which the first game medium can move, and one or more second areas 15 corresponding to one or more vertical paths. It has been. As will be described later, the first area 14 and the second area 15 projected onto the field object are defined as a horizontal path and a vertical path, respectively.

  Further, the storage unit 11 stores correspondence information in which the second object is associated with the texture coordinates of the field image. As will be described later, the correspondence information is used by the control unit 13 that executes a process of placing the second game medium on the field object.

  The display unit 12 is a display device such as a liquid crystal display or an organic EL display, and displays various screens.

  The display unit 12 is configured by a touch panel, for example, and functions as an interface for detecting various user operations.

  For example, the display unit 12 can detect a user's tap operation, long tap operation, flick operation, swipe operation, and the like. The tap operation is an operation in which the user touches the display unit 12 with a finger and then releases the finger. The long tap operation is an operation in which the user touches the display unit 12 with a finger and holds the touch without touching the display unit 12 without moving the finger. The flick operation is an operation in which the user touches the display unit 12 with a finger and moves the finger while touching the display unit 12 while releasing the finger. The swipe operation is an operation in which the user touches the display unit 12 with a finger and holds the finger movably while touching the display unit 12. Preferably, the display unit 12 can detect the above-described operation (for example, multi-tap operation) performed by the user using a plurality of fingers.

  The control unit 13 is a CPU that realizes a specific function by reading a dedicated microprocessor or a specific program. The control unit 13 controls the overall operation of the information processing apparatus 10. For example, the control unit 13 executes a game application in response to a user operation on the display unit 12. Further, the control unit 13 executes various processes related to the game.

  For example, the control unit 13 causes the display unit 12 to display a screen (field screen) on which field objects, first objects, and the like are displayed. The control unit 13 moves the first object on the field object relative to the field object in the virtual space in response to a predetermined user operation on the field screen. This will be specifically described below.

  First, the field object 16 will be described with reference to FIG. The field object 16 is composed of a large number of object elements (for example, a polygonal plane mesh). In the field object 16, an object coordinate system having an Xo axis, a Yo axis, and a Zo axis orthogonal to each other is set. In the present embodiment, the field object 16 has a shape in which a cross-sectional shape in an arbitrary plane substantially parallel to the Yo-Zo plane is extended in the Xo axis direction. For example, the field object 16 has a sheet shape with substantially no thickness. It is an object. In the present specification, the cross-sectional shape of the object includes a cross-sectional shape of the object having substantially no thickness, for example, a shape related to a straight line or a curve, or a combination thereof. In addition, the shape in which the cross-sectional shape is extended includes, for example, the shape of the field object 16 after the object element is added, deformed, or deleted with respect to the field object 16 after the cross-sectional shape is extended. It is. For example, with respect to the field object 16 shown in FIG. 3, the shape of the field object 16 after the concavo-convex shape corresponding to the virtual “mountain” or “valley” is formed, or after some object elements are deleted The shape of the field object 16 is included in the “shape in which the cross-sectional shape is extended”. The field object 16 has a first part 17 and a second part 18.

  The first portion 17 has a substantially planar shape in the present embodiment, and is provided on the Xo-Yo plane. The shape of the first portion 17 is not limited to a planar shape, and for example, the cross-sectional shape of the first portion 17 on an arbitrary surface substantially parallel to the Yo-Zo plane may be a shape having an arbitrary curvature. In such a case, the first portion 17 is provided such that, for example, the end portion of the first portion 17 in the -Yo direction is positioned on the Xo-Yo plane.

  The second portion 18 is a portion (inclined portion) that extends from, for example, an end portion of the first portion 17 in the -Yo direction and is inclined to one surface side (for example, + Zo side) of the Xo-Yo plane. In the present embodiment, the second portion 18 is configured by a combination of a plurality of object elements, but may be configured substantially as a curved surface, for example, by sufficiently reducing the size of each object element. Or each object element which comprises the 2nd site | part 18 may be a curved surface.

  Here, the control unit 13 projects a field image onto the field object 16. The projection of the field image is performed by texture mapping, for example. Specifically, the control unit 13 maps points (texture coordinates) on the field image to a large number of vertices (object coordinates) on the field object 16 and projects the field image onto the field object 16. Here, the vertex is, for example, a vertex in a mesh that is an object element constituting the object.

  As described above, the field object 16 onto which the field image is projected is used as a virtual field (ground) in the game. The first area 14 and the second area 15 on the field image projected onto the field object 16 are defined as a horizontal path 19 and a vertical path 20 to which the first game medium can move, respectively. In the present embodiment, for example, as shown in FIG. 3, a plurality of lateral passages 19 extend substantially parallel to the Xo axis of the object coordinate system. A plurality of vertical passages 20 extend between the two horizontal passages 19 and connect the two horizontal passages 19. Preferably, the longitudinal length (for example, the length in the Xo-axis direction) of the lateral passage 19 is longer than the longitudinal length (for example, the length in the Yo-axis direction) of the longitudinal passage 20.

  Subsequently, the control unit 13 arranges the field object 16 in a three-dimensional virtual space, for example, as shown in FIG. Although only six vertices A to F associated with the field object 16 are illustrated in FIG. 4 for ease of explanation, an arbitrary number of vertices may be set. Here, a world coordinate system having an Xw axis (first axis), a Yw axis (second axis), and a Zw axis that are orthogonal to each other is set in the virtual space. For example, the control unit 13 arranges the field object 16 in the virtual space so that the Xo axis and the Yo axis of the field object 16 and the Xw axis and the Yw axis of the virtual space respectively coincide. Therefore, the second portion 18 (the object elements CD, DE, and EF in FIG. 4) of the field object 16 arranged in the virtual space is on one surface side (for example, + Zw side) of the Xw-Yw plane of the virtual space. Exists.

  Subsequently, the control unit 13 arranges the virtual camera 21 in the virtual space. The virtual camera 21 is used for processing for generating a field screen as will be described later. In the present embodiment, the virtual camera 21 is arranged on the other side (for example, −Zw side) of the Xw-Yw plane of the virtual space so that the optical axis 22 of the virtual camera 21 is substantially parallel to the Yw-Zw plane. The In such a case, the second portion 18 of the field object 16 is inclined downward as viewed from the virtual camera 21 as it moves away in the direction of the optical axis 22 of the virtual camera 21. Preferably, the virtual camera 21 is arranged so that the optical axis 22 intersects the field object.

  Subsequently, the control unit 13 includes a first object 23 on which an image of the first game medium is projected, a second object 24 on which an image of the second game medium is projected, and a background object 25 on which a background image is projected, respectively. Place in the virtual space.

  The first object 23 is arranged at an arbitrary position on the field object 16 in the visual field 26 of the virtual camera 21. In the present embodiment, the first object 23 is disposed on the first part 17 of the field object 16. The first object 23 is a planar object having no thickness, for example. The first object 23 is arranged so that the projection plane of the image satisfies a predetermined condition with respect to the optical axis 22 of the virtual camera 21 (for example, substantially perpendicular to the optical axis 22).

  The second object 24 is arranged at a predetermined position on the field object 16. Specifically, the control unit 13 reads correspondence information in which the second object 24 is associated with the texture coordinates of the field image from the storage unit 11. Subsequently, the control unit 13 arranges the second object 24 at a position (object coordinate) on the field object 16 corresponding to the texture coordinate associated with the second object 24 based on the correspondence information. The object coordinates of the field object 16 corresponding to the texture coordinates associated with the second object 24 are uniquely determined by the texture mapping described above. In the present embodiment, the second object 24 is a planar object having no thickness, for example. The second object 24 is arranged so that the projection plane of the image satisfies a predetermined condition with respect to the optical axis 22 of the virtual camera 21 (for example, substantially perpendicular to the optical axis 22).

  The background object 25 is arranged in the virtual space so that at least a part of the background object 25 is included in the visual field 26 of the virtual camera 21. In the present embodiment, the background object 25 is disposed so as to be in contact with the end portion (vertex F in FIG. 4) of the field object 16 in the −Yw direction of the virtual space. The background object 25 is a planar object having no thickness, for example. The background object 25 is arranged so that the projection plane of the image satisfies a predetermined condition with respect to the optical axis 22 of the virtual camera 21 (for example, substantially perpendicular to the optical axis 22).

  Subsequently, the control unit 13 causes the display unit 12 to display a field screen viewing the virtual space with the virtual camera 21 as a viewpoint. For example, as shown in FIG. 5, a screen coordinate system including an x axis (third axis) and a y axis (fourth axis) orthogonal to each other is set on the field screen. In the present embodiment, the x-axis direction substantially coincides with the longitudinal direction of the field screen (for example, the horizontal direction in FIG. 5), and the y-axis direction substantially coincides with the lateral direction of the field screen (for example, the vertical direction in FIG. 5). To do. In addition, the x-axis direction of the field screen and the Xw-axis direction of the virtual space substantially coincide.

  In the visual field 26 of the virtual camera 21 arranged as described above, for example, as shown in FIG. 4, at least a part of the field object 16, a part of the background object 25, the first object 23, and the second object 24. Can be included. In such a case, the field screen displayed on the display unit 12 includes a field region 27 and a background region 28, as shown in FIG.

  The field area 27 is an area where the field object 16 is displayed, and corresponds to a field (ground) in the virtual space. The background area 28 is an area where the background object 25 is displayed, and corresponds to the sky or the distant view in the virtual space. Here, a field area 27 is provided on the lower side (in the + y direction side in the present embodiment) of the field screen, and a background area 28 is provided on the upper side (in the −y direction side in the present embodiment). The boundary between the field region 27 and the background region 28 corresponds to, for example, a horizon in the virtual space.

  In the field area 27, the horizontal passage 19 and the vertical passage 20 can be displayed. In FIG. 5, two horizontal passages 19a and 19b and one vertical passage 20 connecting the two horizontal passages 19a and 19b are shown.

  A first object 23 is displayed on the field screen. In FIG. 5, two first objects 23 are shown on the lateral passage 19 a, but any number of first objects 23 may exist. As will be described later, the control unit 13 moves the first object 23 relative to the field object 16 in response to a predetermined user operation on the field screen.

  On the field screen, all the second objects 24 included in the visual field 26 of the virtual camera 21 are displayed. In FIG. 5, one second object 24 (building) is shown.

  As described above, each of the first object 23, the second object 24, and the background object 25 is a planar object and is disposed substantially perpendicular to the optical axis 22 of the virtual camera 21 (see FIG. 4). ). Therefore, on the field screen, the first object 23, the second object 24, and the background object 25 are displayed substantially parallel to the field screen (that is, the projection plane of the object faces the screen direction) (see FIG. 5). ).

  Subsequently, the control unit 13 moves the first object 23 relative to the field object 16 on the field object 16 in accordance with a predetermined user operation on the field screen. Here, the relative movement includes moving at least one of the first object 23 and the field object 16 in the virtual space. In the present embodiment, the control unit 13 moves the field object 16 (that is, without substantially changing the world coordinates of the first object 23) (ie, without substantially changing the world coordinates of the first object 23). The first object 23 is moved relative to the field object 16 by changing the world coordinates of the field object 16.

  Here, the display unit 12 included in the information processing apparatus 10 generally has a longitudinal direction (for example, left-right direction) and a short direction (for example, up-down direction), and the field screen in the present embodiment is According to the shape of the display part 12, it has a longitudinal direction and a transversal direction as mentioned above. Therefore, on the field screen, there is a relatively long (large) operation area in the longitudinal direction and a relatively short (small) operation area in the short direction.

  As will be described later, the control unit 13 determines Xw-Zw of the first object 23 based on information obtained in a relatively long operation region in the longitudinal direction of the field screen among information obtained in response to the first user operation. The first object 23 is moved in a direction substantially parallel to the plane. On the other hand, the control unit 13 sets the Yw-Zw plane of the first object 23 based on information obtained in a relatively short operation area in the short direction of the field screen among information obtained in response to the first user operation. The first object 23 is moved in a substantially parallel direction.

  Hereinafter, the operation of the control unit 13 that moves the first object 23 relative to the field object 16 on the field object 16 will be specifically described.

  First, the operation of the control unit 13 that moves the first object 23 relative to the field object 16 in a direction substantially parallel to the Xw-Zw plane (first plane) of the virtual space will be described. In the present embodiment, the first object 23 moves relative to the field object 16 in the Xw axis direction of the virtual space. Here, the movement in the Xw-axis direction means that the Xw-axis direction component of the moving speed of the first object 23 is larger than zero.

  First, the control unit 13 detects a predetermined user operation (first user operation) on the field screen. Further, the control unit 13 detects the first position and the second position on the field screen according to the first user operation while the first user operation is detected.

  In the present embodiment, the first user operation is a swipe operation. The screen coordinates of the first position are screen coordinates corresponding to the position on the field screen that is first designated by the swipe operation. The screen coordinates of the second position are screen coordinates corresponding to the position on the field screen currently designated by the swipe operation. Therefore, in the present embodiment, the screen coordinates of the second position can change from moment to moment according to the first user operation. The first user operation is not limited to the swipe operation, and may be any operation that designates two points on the field screen. For example, the first user operation may be an operation in which the user performs a long tap with two fingers (multi-long tap operation). In such a case, the screen coordinates of both the first position and the second position may change from moment to moment according to the first user operation. Hereinafter, the position vector of the second position with the first position as a reference point is also referred to as a first input vector.

  Subsequently, the control unit 13 follows the Xw axis according to the x-axis direction component of the length between the first position and the second position (that is, the absolute value of the x-axis direction component of the first input vector). The moving speed of the first object 23 is determined. In the present embodiment, the longer the x-axis direction component of the length between the first position and the second position, the greater the moving speed of the first object 23 along the Xw axis. The moving speed of the first object 23 along the Xw axis may change continuously or in steps depending on the x-axis direction component of the length between the first position and the second position. May be. Here, the aspect in which the moving speed continuously changes includes an aspect in which the range corresponding to each stage of the axial component of the moving speed is sufficiently small among the aspects in which the moving speed changes stepwise. Also good.

  Subsequently, the control unit 13 determines the first object 23 according to the sign (ie, the direction of the x-axis direction component of the first input vector) obtained by subtracting the x coordinate of the second position from the x coordinate of the first position. The moving direction is determined in the + Xw direction or the −Xw direction of the world coordinate system. Then, the control unit 13 moves the first object 23 relative to the field object 16 at the determined moving speed in the determined direction.

  In the present embodiment, when the direction of the x-axis direction component of the first input vector is the + x direction, the control unit 13 determines the moving direction of the first object 23 as the + Xw direction of the world coordinate system. Then, the control unit 13 translates the field object 16 in the −Xw direction in the virtual space without substantially moving the first object 23 in the virtual space. On the other hand, when the direction of the x-axis direction component of the first input vector is the −x direction, the control unit 13 determines the moving direction of the first object 23 as the −Xw direction of the world coordinate system. Then, the control unit 13 translates the field object 16 in the + Xw direction in the virtual space without substantially moving the first object 23 in the virtual space.

  Here, with reference to FIG. 5 thru | or FIG. 7, operation | movement of the control part 13 mentioned above is demonstrated concretely. For example, the control unit 13 detects the first position and the second position while the first user operation is detected with the field screen shown in FIG. 5 displayed on the display unit 12. For example, as shown in FIG. 6, when the second position 30 is located on the upper left of the field screen with respect to the first position 29, the direction of the x-axis direction component of the first input vector 31 is the −x direction. . Therefore, the control unit 13 translates the field object 16 in the + Xw direction in the virtual space without substantially moving the first object 23 in the virtual space. At this time, on the field screen, for example, as shown in FIG. 7, the position (screen coordinates) of the first object 23 does not substantially change, and the field objects 16 and 16 displayed in the field region 27 and the background region 28 respectively. The background object 25 moves so as to flow toward the right direction (+ x direction) of the screen.

  Preferably, when the control unit 13 detects the end of the first user operation (for example, the user performing the swipe operation releases his finger from the display unit 12), the control unit 13 changes the moving speed of the first object 23 while changing the moving speed of the first object 23. One object 23 is moved in the Xw axis direction. In the present embodiment, the control unit 13 moves the first object 23 while decelerating the moving speed of the first object 23 at a predetermined time change rate in response to the detection of the end of the first user operation. With this configuration, the first object 23 continues to move in the Xw-axis direction while decelerating even when the user lifts his / her finger from the display unit 12, so that the first object 23 is moved along the lateral passage 19 for a relatively long distance. The operation burden on the user is reduced, and the operability of the game is improved.

  Here, the time change rate of the moving speed of the first object 23 may be a constant or may be calculated by the control unit 13. For example, the control unit 13 may calculate the time change rate according to the moving speed of the first object 23 so that the time change rate becomes larger or smaller as the moving speed of the first object 23 becomes larger. Further, for example, a predetermined parameter indicating the characteristics of the first game medium such as weight or quickness is set in the first object 23, and the control unit 13 increases the time of the moving speed of the first object 23 as the parameter increases. The time change rate may be calculated according to the parameter so that the change rate is large or small. In addition, for example, a predetermined parameter indicating the state of the ground such as asphalt or mud is set in a partial area on the field object 16, and the control unit 13 determines the moving speed time of the first object 23 according to the parameter. The rate of change may be calculated.

  Preferably, when the control unit 13 detects a predetermined user operation (second user operation) on the field screen while moving the first object 23 while changing the moving speed as described above, The moving speed of one object 23 is set to a predetermined value. In the present embodiment, the control unit 13 sets the moving speed of the first object 23 to zero in response to detection of the second user operation. Here, the second user operation is a tap operation performed at an arbitrary position on the field screen, for example, but may be an arbitrary user operation such as a multi-tap operation. With this configuration, as described above, the user changes the moving speed of the first object 23 that moves in the Xw-axis direction while changing the moving speed to a predetermined value at an arbitrary timing (for example, stops the first object 23). ) And the operability of the game is improved.

  Next, the operation of the control unit 13 that moves the first object 23 relative to the field object 16 in a direction substantially parallel to the Yw-Zw plane (second plane) of the virtual space will be described. In the present embodiment, the first object 23 moves relative to the field object 16 in the Yw axis direction of the virtual space. Here, the movement in the Yw-axis direction means that the Yw-axis direction component of the moving speed of the first object 23 is larger than zero.

  First, the control unit 13 determines whether or not the first object 23 is located within a predetermined area 32 in the vicinity of the vertical passage 20. When it is determined that the first object 23 is located in the region 32, the control unit 13 satisfies a predetermined condition (first condition) regarding a change in the second position according to the detected first user operation. Determine whether or not.

  In the present embodiment, the first condition is the y-axis direction component of the length between the second position before the change and the second position after the change, that is, after the change with the second position before the change as the reference point. The condition that the absolute value of the y-axis direction component of the position vector of the second position (second input vector) is greater than or equal to a predetermined threshold, or y of the change speed of the second position that changes according to the first user operation This includes a condition that the absolute value of the axial direction component (that is, the magnitude of the y-axis direction component of the velocity vector at the second position) is equal to or greater than a predetermined threshold.

  Preferably, the first condition is that the vertical path 20 corresponding to the region 32 described above is positioned in the −Yw direction with respect to the first object 23 (for example, the vertical path 20 extends to the depth side on the field screen). ) The value obtained by subtracting the y coordinate of the second position after the change from the y coordinate of the second position before the change is negative (that is, the direction of the y-axis direction component of the second input vector is the -y direction). And a condition of Preferably, the first condition is that the vertical path 20 corresponding to the region 32 described above is positioned in the + Yw direction with respect to the first object 23 (for example, the vertical path 20 extends to the near side on the field screen). ) When the value obtained by subtracting the y coordinate of the second position after the change from the y coordinate of the second position before the change is positive (that is, the direction of the y-axis direction component of the second input vector is the + y direction). The conditions are further included.

  When it is determined that the first condition is satisfied, the control unit 13 moves the first object 23 relative to the field object 16 in a direction substantially parallel to the Yw-Zw plane of the virtual space by a predetermined distance in the virtual space. Move. Specifically, the control unit 13 slides the field object 16 by a predetermined distance in the virtual space without substantially moving the first object 23 in the virtual space. When the field object 16 slides, vertices existing on a plane substantially parallel to the Yw-Zw plane among a plurality of vertices on the field object 16 move along a predetermined trajectory on the plane. Here, the shape of the predetermined trajectory substantially matches the shape obtained by extending the cross-sectional shape of the field object 16 on the plane substantially parallel to the Yw-Zw plane. Therefore, for example, in FIG. 8, when the field object 16 slides, each of the vertices A to F of the field object 16 on a plane substantially parallel to the Yw-Zw plane slides along the cross-sectional shape of the field object 16. Move to. That is, the control unit 13 moves the field object 16 while changing the shape of the field object 16. The predetermined distance is, for example, the length in the longitudinal direction of the vertical passage 20 (in this embodiment, the Yw axis direction).

  Preferably, the control unit 13 causes the projection planes of the images of the first object 23, the second object 24, and the background object 25 to move relative to the optical axis 22 of the virtual camera 21 while the field object 16 slides. Control is performed so as to satisfy the above-described conditions (for example, substantially perpendicular to the optical axis 22). Specifically, the control unit 13 slides the field object 16 and at the same time changes the angle formed by the first object 23 and the field object 16, for example, so that the projection surface of the first object 23 has the optical axis 22. Is controlled so as to be substantially perpendicular to. With this configuration, even when the field object 16 slides, the first object 23, the second object 24, and the background object 25 are substantially parallel to the field screen on the field screen (that is, the projection plane of the object). Is displayed (facing the screen), the visibility of the field screen is improved.

  Here, with reference to FIG. 7 thru | or FIG. 11, operation | movement of the control part 13 mentioned above is demonstrated concretely. For example, the control unit 13 detects a change in the second position according to the first user operation in a state where the field screen illustrated in FIG. 7 is displayed on the display unit 12. Here, the first object 23 is located in a predetermined area 32 in the vicinity of the vertical passage 20 located on the −Yw side of the world coordinate system with respect to the first object 23. Further, as shown in FIG. 9, the second position 33 after the change is located at the upper left on the field screen with respect to the second position 30 before the change, and the above-described first condition relating to the change in the second position is satisfied. It is assumed that

  In such a case, the control unit 13 moves the first object 23 in the −Yw direction by a predetermined distance in the virtual space. Specifically, the control unit 13 slides the field object 16 in the + Yw direction in the virtual space by the length in the longitudinal direction of the vertical passage 20 without substantially moving the first object 23 in the virtual space. Move (see FIG. 8). At this time, on the field screen, for example, as shown in FIG. 10, the field object 16 slides toward the front side of the screen without substantially changing the position (screen coordinates) of the first object 23. As shown in FIG. 11, the first object 23 moves to the other side passage 19b.

  As described above, the control unit 13 moves the first object 23 on the field object 16 relative to the field object 16 in the virtual space in response to a user operation on the field screen.

  Further, the control unit 13 executes different processes depending on the position of the first object 23 on the field object 16. For example, the field object 16 has different areas (first specific area and second specific area) that are continuous (adjacent) in the Xo-axis direction (in this embodiment, the same as the Xw-axis direction). The first object 23 can be moved back and forth between the first specific area and the second specific area (for example, without switching the field screen display or darkening). For example, the first specific area corresponds to the inside of a virtual town in the game, and the second specific area corresponds to the outside of the town. In such a case, when the first object 23 exists in the first specific area, the control unit 13 performs, for example, the first object 23 (user character) and the second object 24 (for example, an NPC that is a resident of the city). Execute processing such as conversation. On the other hand, when the first object 23 exists in the second specific area, the control unit 13 executes a process such as a battle between the first object 23 (user character) and the enemy character, for example. Further, for example, the control unit 13 may reproduce different music data (BGM) depending on whether the first object 23 exists in the first specific area or the second specific area.

  Next, the operation of the information processing apparatus 10 will be described with reference to the flowchart shown in FIG. This operation is performed, for example, in a state where the field screen is displayed during execution of the first game part.

  Step S100: First, the control unit 13 waits for detection of a first user operation on the field screen. The first user operation is, for example, a swipe operation. When the first user operation is detected (step S100-Yes), the process proceeds to step S101.

  Step S101: Subsequently, the control unit 13 detects the first position on the field screen according to the first user operation. The first position is a position (screen coordinates) on the field screen that is first designated by, for example, a swipe operation.

  Step S102: Subsequently, the control unit 13 detects the second position on the field screen according to the first user operation. The second position is a position (screen coordinates) on the field screen currently designated by, for example, a swipe operation.

  Step S103: Subsequently, the control unit 13 executes a process of moving the first object 23 in a direction substantially parallel to the Xw-Zw plane based on the first position and the second position. Details of this processing will be described later.

  Step S104: Subsequently, the control unit 13 executes a process of moving the first object 23 in a direction substantially parallel to the Yw-Zw plane according to the change in the second position. Details of this processing will be described later.

  Step S105: Subsequently, the control unit 13 determines whether or not the end of the first user operation is detected. When it is determined that the end of the first user operation is detected (step S105-Yes), the process proceeds to step S106. On the other hand, when it is determined that the end of the first user operation has not been detected (step S105—No), the process returns to step S102.

  Step S106: When it is determined that the end of the first user operation is detected in Step S105 (Step S105-Yes), the control unit 13 changes the moving speed of the first object 23 (for example, decelerates) One object 23 is moved in the Xw axis direction.

  Step S107: Subsequently, the control unit 13 determines whether or not a second user operation has been detected. The second user operation is a tap operation performed at an arbitrary position on the field screen, for example. When it is determined that the second user operation has been detected (step S107—Yes), the process proceeds to step S108. On the other hand, when it is determined that the second user operation is not detected (step S107—No), the process proceeds to step S109.

  Step S108: When it is determined in step S107 that the second user operation has been detected (step S107-Yes), the control unit 13 sets the moving speed of the first object 23 to a predetermined value (for example, zero).

  Step S109: When it is determined in step S107 that the second user operation has not been detected (No in step S107), or after step S108, the control unit 13 has newly detected the first user operation. Determine. When it is determined that the first user operation is newly detected (step S109—Yes), the process returns to step S101. On the other hand, when it is determined that the first user operation has not been newly detected (No at Step S109), the process returns to Step S106.

  Next, the details of the movement process (step S103) in the direction substantially parallel to the Xw-Zw plane described above will be described with reference to the flowchart shown in FIG.

  Step S200: First, the control unit 13 determines the moving speed and moving direction of the first object 23 based on the first position and the second position corresponding to the first user operation. Specifically, the control unit 13 determines the first object 23 according to the x-axis direction component of the length between the first position and the second position (absolute value of the x-axis direction component of the first input vector). Determine the speed of movement. In addition, the control unit 13 determines the moving direction of the first object 23 according to the sign of the value obtained by subtracting the x coordinate of the second position from the x coordinate of the first position (the direction of the x-axis direction component of the first input vector). Determine in the + Xw direction or the -Xw direction.

  Step S201: The control unit 13 moves the first object 23 relative to the field object 16 in the Xw axis direction of the world coordinate system. Here, the moving speed and moving direction of the first object 23 are the moving speed and moving direction determined in step S200. Then, it progresses to step S104 mentioned above (refer FIG. 12).

  Next, the details of the movement process (step S105) in the direction substantially parallel to the Yw-Zw plane described above will be described with reference to the flowchart shown in FIG.

  Step S300: First, the control unit 13 determines whether or not the first object 23 is located in the predetermined area 32 in the vicinity of the vertical passage 20. When it is determined that the first object 23 is located in the region 32 (step S300—Yes), the process proceeds to step S301. On the other hand, when it is determined that the first object 23 is not located in the region 32 (step S300—No), the process proceeds to the above-described step S105 (see FIG. 12).

  Step S301: When it is determined in step S300 that the first object 23 is located in the region 32 (step S300-Yes), the control unit 13 performs the above-described first regarding change in the second position in response to the first user operation. Determine whether the condition is met. When it is determined that the first condition is satisfied (step S301—Yes), the process proceeds to step S302. On the other hand, when it is determined that the first condition is not satisfied (step S301-No), the process proceeds to the above-described step S105 (see FIG. 12).

  Step S302: When it is determined in Step S301 that the first condition is satisfied (Step S301-Yes), the control unit 13 sets the first object in a direction substantially parallel to the Yw-Zw plane by a predetermined distance in the virtual space. 23 is moved relative to the field object 16. Here, the predetermined distance is, for example, the length of the longitudinal passage 20 in the longitudinal direction (in this embodiment, the Yw-axis direction).

  As described above, the information processing apparatus 10 according to the present embodiment moves the first object 23 relative to the field object 16. Here, the field object 16 is arranged in a virtual space, and a cross-sectional shape in a plane substantially parallel to the Yw-Zw plane (first plane) extends in the Xw axis (first axis) direction. There is an inclined portion that is inclined downward as viewed from the virtual camera 21 as it is away from the virtual camera 21 in the direction of the optical axis 22. With this configuration, as will be described below, the visibility of the field screen is improved, and a field screen suitable for the information processing apparatus 10 including the display unit d12 with a limited screen size, such as a smartphone, can be realized.

  For example, a display device provided in a smartphone or the like generally has different dimensions in the left-right direction and the up-down direction, and generally has a relatively small screen size. For this reason, for example, a field screen overlooking a flat field from the sky can display the field only within a relatively small display area in the short direction of the screen. On the other hand, according to the information processing apparatus 10 described above, at least a part of the inclined portion of the field object 16 is displayed as a field spreading in the depth direction on the field screen. In other words, since at least a part of the inclined portion is distorted (compressed) in the short direction of the field screen, the range of fields displayed at one time on the screen is expanded and the visibility of the field screen is improved. To do. The field object 16 has a shape extending in the longitudinal direction (left-right direction) on the field screen. For this reason, the distortion in the screen longitudinal direction of the field object 16 displayed on the field screen is reduced, and the visibility of the field screen is improved.

  Further, when the information processing apparatus 10 moves the first object 23 in a direction substantially parallel to the Xw-Zw plane (second plane), the information processing apparatus 10 translates the field object 16 in the Xw axis (first axis) direction. In addition, when the information processing apparatus 10 moves the first object 23 in a direction substantially parallel to the Yw-Zw plane (first plane), the information processing apparatus 10 performs a field different from the parallel movement in a direction substantially parallel to the Yw-Zw plane. The object 16 is moved. With such a configuration, different visual effects are realized when the first object 23 is moved in the short direction of the field screen and when the first object 23 is moved in the long direction, and the spread in the depth direction of the field on the field screen can be displayed. For example, the visibility of the field screen is improved as compared with a configuration in which the screen is scrolled and displayed in both the horizontal direction and the vertical direction.

  Further, the information processing apparatus 10 performs control so that the image projection planes of the first object 23 and the second object 24 satisfy a predetermined condition with respect to the optical axis 22 of the virtual camera 21. With this configuration, the first object 23 and the male second object 24 are displayed substantially parallel to the field screen on the field screen, so that the visibility of the field screen is further improved.

  The field object 16 includes a first part 17 and a second part 18 extending from the end of the first part 17. With this configuration, for example, the field is displayed relatively large on the front side of the field screen, and the field is compressed and displayed in the vertical direction by the second portion 18 on the depth side, so that the display unit 12 with a limited display area is displayed. Suitable field screens can be realized.

  The field object 16 has a first specific area and a second specific area that are arranged in the virtual space and are continuous in the Xw-axis direction. The information processing apparatus 10 executes different processes depending on whether the first object 23 exists in the first specific area and the first object 23 exists in the second specific area. With this configuration, the first object 23 (user character) can move seamlessly into and out of the town, for example. Therefore, for example, compared to a configuration in which the display of the screen is switched when moving in and out of the town, occurrence of an uncomfortable feeling in the expression of switching the screen is suppressed, and generation of a waiting time until the screen is switched is suppressed. In this way, a user experience that perceives the continuity of the field in the game can be realized.

  Further, the information processing apparatus 10 according to the present embodiment detects the first position and the second position while the first user operation is detected. The information processing apparatus 10 moves the first object 23 in a direction substantially parallel to the Xw-Zw plane (first plane) based on both the first position and the second position, and changes the second position according to the change in the second position. The first object 23 is moved in a direction substantially parallel to the Yw-Zw plane (second plane). As described above, of the information detected in response to the first user operation, different information is used for movement in a direction substantially parallel to the first plane and movement in a direction substantially parallel to the second plane. With this configuration, for example, when the user wants to move the first object 23 in a direction substantially parallel to the first plane, the first object 23 is in a direction substantially parallel to the second plane due to a slight positional shift of the first user operation. Since the occurrence of movement of the first object 23 in a direction not intended by the user, such as movement, is suppressed, the operability of the game is improved.

  Further, when detecting the end of the first user operation, the information processing apparatus 10 moves the first object 23 in the Xw axis direction while changing (for example, decelerating) the moving speed of the first object 23. With this configuration, the first object 23 continues to move in the Xw-axis direction while decelerating even when the user lifts his / her finger from the display unit 12, so that the first object 23 is moved along the lateral passage 19 for a relatively long distance. The operation burden on the user is reduced, and the operability of the game is further improved.

  Further, when the information processing apparatus 10 detects the second user operation while moving the first object 23 in the Xw-axis direction while changing the moving speed of the first object 23, the information processing apparatus 10 sets the moving speed of the first object 23. A predetermined value (for example, zero) is set. With this configuration, as described above, the user changes the moving speed of the first object 23 that moves in the Xw-axis direction while changing the moving speed to a predetermined value at an arbitrary timing (for example, stops the first object 23). And the operability of the game is further improved.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, the functions included in each means, each step, etc. can be rearranged so that there is no logical contradiction, and a plurality of means, steps, etc. can be combined or divided into one. .

  For example, when the control unit 13 detects a change in the second position in response to the first user operation while moving the first object 23 in the Xw-axis direction in response to the first user operation, When the changing speed (that is, the magnitude of the speed vector of the second position) is equal to or greater than a predetermined threshold, the moving speed of the first object 23 is set to a predetermined value (for example, zero), and the first user operation is terminated. You may determine with having detected. With this configuration, the user who performs the first user operation can perform a simple operation of quickly moving the finger touching the display unit 12 while moving the first object 23 in the Xw axis direction at a relatively high speed, for example. The speed of the first object 23 can be changed to a predetermined value. For this reason, the operability of the game is further improved.

  Alternatively, the control unit 13 may cause the first object 23 to execute a predetermined action such as jumping other than the movement, when the change speed of the second position is equal to or greater than a predetermined threshold. With this configuration, for example, when an obstacle (game medium) such as a rock or a pit exists on the side passage 19, the user who performs the first user operation does not end the first user operation (for example, the display unit) The first object 23 can be made to jump over the obstacle without releasing the finger from the object 12. Therefore, the operability of the game is further improved, and the action property of the game is formed, so that the fun of the game is improved.

  Further, for example, when the control unit 13 moves the first object 23 in the Yw-axis direction while the first user operation is detected (that is, without detecting the end of the first user), the first unit The screen coordinates of the first position detected in response to the detection of the user operation may be automatically updated from the screen coordinates of the position on the field screen first designated by, for example, the swipe operation to other screen coordinates.

  Specifically, the control unit 13 moves the first object 23 in the Yw-axis direction while the first user operation is detected (for example, the field screen shown in FIG. When a change in the second position in response to the first user operation is detected, the screen coordinates of the second position before the change are determined as the screen coordinates of the new first position.

  Preferably, the control unit 13, for example, as shown in FIG. 15A, indicates the direction of the y-axis direction component of the position vector 34 of the second position 33 before the change with the first position 29 as a reference point (in the drawing). Then, the direction of the y-axis direction component of the position vector 36 of the second position 35 after the change (that is, the second input vector) with the second position 33 before the change as the reference point (in the drawing, in the figure). , + Y direction), the second position 33 before the change is determined as a new first position 37 as shown in FIG.

With such a configuration, for example, while the first object 23 is moving along the vertical path 20, the user moves the finger a relatively short distance while touching the display unit 12, thereby causing the first object 23 to move to the other. After moving to the horizontal passage 19b, the first object 23 can be moved in any direction along the Xw axis. Specifically, for example, as shown in FIG. 7, the user moves the first object 23 in the −Xw direction in the lateral passage 19a on the near side, and moves the first object 23 along the vertical passage 20 in the −Yw direction. 15 (see FIG. 10), when it is desired to move the first object 23 in the + Xw direction in the other lateral passage 19b (see FIG. 11), for example, the finger is moved from the first position 29 in FIG. There is no need to move to + x side. Therefore, the complexity of the mobile user operation is reduced.

  In the above-described embodiment, the first direction in the direction substantially parallel to the Yw-Zw plane of the virtual space depends on whether or not the first condition related to the change in the second position according to the first user operation is satisfied. Although the configuration in which the object 23 is moved relative to the field object 16 has been described, it is substantially parallel to the Yw-Zw plane of the virtual space based on both the first position and the second position according to the first user operation. The first object 23 may be moved in any direction.

  Specifically, first, the control unit 13 determines whether or not the first object 23 is located within a predetermined area 32 in the vicinity of the vertical passage 20. When it is determined that the first object 23 is located in the region 32, the control unit 13 detects the first user operation and the first position and the second position corresponding to the first user operation. Subsequently, the control unit 13 sets the Yw-Zw plane according to the y-axis direction component of the length between the first position and the second position (that is, the absolute value of the y-axis direction component of the first input vector). The moving speed of the first object 23 in the substantially parallel direction is determined. For example, the longer the y-axis direction component between the first position and the second position, the greater the moving speed of the first object 23 in the direction substantially parallel to the Yw-Zw plane. Here, when the first object 23 is moved at the determined moving speed, the first object 23 may be accelerated by using the determined moving speed as an upper limit. The moving speed of the first object 23 in the direction substantially parallel to the Yw-Zw plane may continuously change according to the y-axis direction component of the length between the first position and the second position, It may change in stages.

  Here, preferably, the control unit 13 determines whether or not the y-axis direction component of the length between the first position and the second position is greater than or equal to a predetermined threshold value. When it is determined that the y-axis direction component of the length between the first position and the second position is greater than or equal to a predetermined threshold, the control unit 13 moves the first object 23 in a direction substantially parallel to the Yw-Zw plane. Move to. On the other hand, when it is determined that the y-axis direction component of the length between the first position and the second position is less than the threshold, the control unit 13 moves the first object 23 in a direction substantially parallel to the Yw-Zw plane. The moving speed of the first object 23 in the direction substantially parallel to the Yw-Zw plane of the first object 23 is set to zero.

Preferably, the moving speed (moving speed) of the first object 23 along the Xw axis when the x-axis direction component of the length between the first position and the second position is a predetermined value (specific value). Xw) and the moving speed (moving speed) of the first object 23 in a direction substantially parallel to the Yw-Zw plane when the y-axis direction component of the length between the first position and the second position is the specific value. Yw) is different. In this way, the control unit 13 determines the moving speed Xw and the moving speed Yw using different algorithms using the first position and the second position according to the first user operation.

  Here, as described above, since the display unit 12 has a longitudinal direction (for example, the left-right direction) and a short direction (for example, the up-down direction), the length (size) of the operation area on the screen is shorter than the longitudinal direction. It differs depending on the hand direction. Here, the touch panel generally has the same detection pitch in the horizontal direction and the vertical direction. Therefore, the number of points that can detect the user operation in the short direction of the screen is smaller than the number of points that can detect the user operation in the longitudinal direction of the screen. For this reason, for example, in the configuration in which the algorithm for determining the moving speed Xw of the first object 23 is the same as the algorithm for determining the moving speed Yw, the operation in the short direction is compared with the operation region in the long direction. The operability of the game in the area is low. On the other hand, since the control unit 13 determines the moving speed Xw and the moving speed Yw by different algorithms using the first position and the second position, the length of the operation area in the longitudinal direction on the field screen as described above. In a configuration in which the length (size) is different from the length (size) of the operation area in the short direction, the operability of the game in the operation area in the short direction can be further improved.

  For example, the moving speed Yw when the y-axis direction component is a specific value is set to be smaller or larger than the moving speed Xw when the x-axis direction component is a specific value. Preferably, when the y-axis direction is the short direction, the moving speed Yw is determined to be larger than the moving speed Xw. Here, the specific value may be an arbitrary value that can be taken by the y-axis direction component (short direction component) of the length between the first position and the second position.

  Specifically, the moving speed Xw and the moving speed Yw of the first object 23 change continuously according to the x-axis direction component and the y-axis direction component of the length between the first position and the second position, respectively. In the configuration, the length between the first position and the second position is larger than the rate of change in the moving speed Xw with respect to the x-axis direction component of the length between the first position and the second position. The rate of change in the movement speed Yw with respect to the axial component is small or large.

  More specifically, the moving speed Xw and the moving speed Yw of the first object 23 change stepwise according to the x-axis direction component and the y-axis direction component of the length between the first position and the second position. In the case of the configuration, the number of stages of the moving speed Xw and the number of stages of the moving speed Yw may be different. For example, the control unit 13 sets the speed value at the stage according to the x-axis direction component of the length between the first position and the second position among the speed values at n stages (2 <n) as the moving speed Xw. decide. Further, the control unit 13 moves the speed value corresponding to the stage corresponding to the y-axis direction component of the length between the first position and the second position among the m stage (1 <m <n) speed values. Determined at speed Yw. Here, the speed value corresponding to each stage may be set at equal intervals (for example, 0, 5, 10,...), Or set at different intervals (for example, 0, 1, 5, 15,...). May be. In addition, the range corresponding to each step of the axial component of the moving speed may be set to the same size (for example, 5 pixels) or set to different sizes (for example, 5 pixels or 10 pixels). May be.

  Further, in the above-described embodiment, the configuration in which the moving speed Xw of the first object 23 is changed according to the end of the first user operation has been described, but the moving speed Yw may be changed similarly. Specifically, when detecting the end of the first user operation, the control unit 13 moves the first object 23 while changing at least one of the moving speed Xw and the moving speed Yw of the first object 23.

  In the above-described embodiment, the configuration in which the field object 16 is moved without substantially moving the first object 23 when the first object 23 is moved relative to the field object 16 has been described. For example, the first object 23 may be moved without substantially moving the field object 16. In such a configuration, the control unit 13 moves the virtual camera 21 according to the movement of the first object 23 so that the relative positional relationship between the virtual camera 21 and the first object 23 is maintained.

  In the above-described embodiment, the configuration in which the field object 16 arranged in the three-dimensional virtual space is used as the field (ground) has been described. However, for example, a two-dimensional virtual space may be used. In such a case, the field, the first game medium, the second game medium, the background, and the like are all composed of two-dimensional images.

  Further, although the game according to the above-described embodiment has been described as a role playing game, a simulation game, or the like, the present invention is applicable to games of various genres in which a game medium is moved on a field in the game. is there.

  Further, the information processing apparatus 10 may be able to communicate with the server apparatus via the Internet, for example. In such a configuration, when the first object 23 moves to a predetermined position on the field (for example, an entrance of a cave or a building), the information processing apparatus 10 can detect another field image (for example, the interior of the cave or the building). Is acquired from the server device. Then, the information processing apparatus 10 projects another field image received from the server apparatus onto another newly generated (defined) field object, and arranges the first object 23 and the like on the other field object. With such a configuration, field variations are increased and the fun of the game is improved as compared to a configuration using only field images stored in the information processing apparatus 10 itself.

  In the above-described embodiment, the configuration in which the field object 16 includes the first part 17 and the second part 18 has been described. However, the shape of the field object 16 is not limited thereto. The field object 160 according to the modified example of the embodiment has a cylindrical shape extending in the Xo-axis direction in the object coordinate system, and the virtual camera 21 is arranged in the virtual space in the same manner as the above-described embodiment. And an inclined portion that inclines downward as viewed from the virtual camera 21 as it moves away in the optical axis 22 direction. Specifically, the field object 160 has a rectangular tube shape or substantially cylindrical shape that is rotationally symmetric with respect to the Xo axis, or a rectangular tube shape or substantially elliptical cylinder shape that is rotationally asymmetric with respect to the Xo axis. For example, FIG. 16 shows that the field object 160 having a square cylinder shape rotationally symmetric with respect to the Xo axis is arranged in the virtual space in the same manner as in the above-described embodiment, and the field object 160 is substantially parallel to the Yw-Zw plane. It is sectional drawing cut | disconnected by the plane. In FIG. 16, for example, object elements CD, DE, and the like correspond to inclined portions.

  In the configuration in which the field object 160 is employed, when it is determined that the first condition described above is satisfied, the control unit 13 performs a predetermined distance in the virtual space in a direction substantially parallel to the Yw-Zw plane of the virtual space. The first object 23 is moved relative to the field object 160. Specifically, the control unit 13 rotates the field object 160 around the Xw axis in the virtual space without substantially moving the first object 23 in the virtual space. When the field object 16 rotates, each vertex existing on a plane parallel to the Yw-Zw plane among the plurality of vertices on the field object 16 follows a concentric circle trajectory centered on the Xw axis on the plane. Move.

  In the above-described embodiment, a part of various game screens is a web display that is displayed on the information processing device 10 based on data generated by a server device that can communicate with the information processing device 10. A part of (for example, a header area and a footer area where menu buttons are arranged) may be displayed natively by a native application installed in the information processing apparatus 10. As described above, the game according to the above-described embodiment may be a hybrid game in which each of the information processing apparatus 10 and the server apparatus assumes a part of processing.

  Moreover, in order to make it function as the information processing apparatus 10 which concerns on embodiment mentioned above, the apparatus which can perform information processing, such as a computer or a mobile telephone, can be used suitably. Such an apparatus is realized by storing a program describing processing contents for realizing each function of the information processing apparatus 10 according to the embodiment in a storage unit of the apparatus, and reading and executing the program by the CPU of the apparatus. Is possible.
