Description

The present invention relates to a program, a game control method, and an information processing device.

Conventionally, games in which a character or the like arranged in a virtual space is moved in response to a user operation are known. For example, Patent Literature 1 discloses a game in which a user character is moved on a map in response to a user operation, and when the user character encounters an enemy character, the user character and the enemy character fight each other.

Japanese Patent Application Publication No. 11-179048

In recent years, games are executed on information processing devices equipped with touch panels, such as smartphones. However, when a game is operated using a touch panel, the operability may not be sufficient. For example, in a game in which a user moves a character in a direction determined by a swipe operation in which the user moves a finger while touching the touch panel, the character may move in a direction not intended by the user due to a slight positional shift of the swipe operation. Therefore, there is room for improvement in the operability of the game.

The following describes an embodiment of the present invention.

First, an information processing device 10 according to an embodiment of the present invention will be described with reference to Fig. 1. The information processing device 10 is, for example, a smartphone, a PC, a gaming device, or the like, and is capable of executing a game application according to this embodiment. The game application may be received from a predetermined application distribution server via the Internet, for example, or may be stored in advance in a storage device provided in the information processing device 10 or a storage medium such as a memory card that can be read by the information processing device 10.

Here, an overview 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, in which the game medium is moved on a field within the game.

Game media is electronic data used in a game, and includes any media, such as cards, items, characters, avatars, objects, etc. In addition, game media is electronic data that can be acquired, owned, used, managed, exchanged, synthesized, strengthened, sold, discarded, and/or donated by a user within a game, but the manner of use of the game media is not limited to those explicitly stated in this specification.

Hereinafter, unless otherwise specified, "game media owned by a user" refers to game media associated with a user ID of a user. Furthermore, "granting a game medium to a user" refers to associating the game medium with a user ID. Furthermore, "discarding a game medium owned by a user" refers to dissociating the association between a user ID and the game medium. Furthermore, "consuming a game medium owned by a user" refers to the possibility of generating some effect or influence in the game in response to dissociation of the association between a user ID and the game medium. Furthermore, "selling a game medium owned by a user" refers to dissociating the association between a user ID and the game medium, and associating the user ID with another game medium (e.g., virtual currency or an item, etc.). Furthermore, "transferring a game medium owned by user A to user B" refers to dissociating the association between user A's user ID and the game medium, and associating the game medium with user B's user ID.

The game according to this embodiment generally comprises a first game part, a second game part, and
A third game part.

In the first game part, the user operates a user character to progress through the game while exploring a field in the game. Specifically, the user character moves on the field in response to the user's operation. Various areas, such as towns and dungeons, are provided in the field, and various events occur according to the area, such as conversations with town resident characters and battles with enemy characters encountered in dungeons. The main story of the game progresses as the events are executed. In addition, in the first game part, if the user wins a battle against an enemy character, game media such as items, virtual currency, or characters may be granted to the user. The granted game media can be used, for example, in a third game part described later.

As described later, the field according to this embodiment is provided with passages through which the user character can move. Specifically, a plurality of passages (horizontal passages) extending substantially parallel in one direction (e.g., left-right direction) on the screen, and a plurality of passages (vertical passages) extending in another direction (e.g., up-down direction) on the screen and connecting the two horizontal passages are provided. As described later, in this embodiment, the user character moves along the horizontal passages at a moving speed according to a predetermined user operation on the game field. On the other hand, the user character moves along the vertical passages on the game field by a predetermined distance, for example, the distance from one horizontal passage to another horizontal passage. Thus, in this 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. The 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 the user moves the user character to a specific area such as a mining site or a fishing pond provided on the field, or selects a game media such as a specific character or object (for example, by touching the screen), a sub-event occurs in which the game media can be acquired. Sub-events include, for example, the progression of a sub-story and the execution of a mini-game, but the contents of the sub-events are not limited to these. Depending on the result of the execution of the sub-event, various game media can be granted to the user. The granted game media can be used, for example, in the third game part described later.

In the third game part, the user, for example, strengthens the user character. Specifically, as described above, various game parameters of the user character change as the game media provided to the user in the first game part and the second game part are consumed. The game parameters include, for example, but are not limited to, the user character's level, HP, attack power, defense power, attributes, and skills. The user character is strengthened in response to the change in the game parameters of the user character. Strengthening the user character increases the probability that the user character will win in a battle against an enemy character in the first game part.

In this way, in the game according to this embodiment, the user repeatedly plays the first game part, the second game part, and the third game part.

Next, a description will be given of each component of the information processing device 10. The information processing device 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 a game application.

The storage unit 11 also stores various images (texture images) to be projected (texture mapping) onto various objects placed in a three-dimensional virtual space.

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

The storage unit 11 also stores images of, for example, buildings, walls, trees, NPCs (Non Player Characters), etc. Hereinafter, the buildings, walls, trees, NPCs, etc. are referred to as second game media, and objects onto which images of the second game media are projected are also referred to as second objects.

The storage unit 11 also stores an image of a background (background image), such as the sky or a distant view. The background image is projected onto a background object, which will be described later.

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

Here, a texture coordinate system having mutually orthogonal u-axis and v-axis is set in the field image, for example as shown in FIG.
A plurality of first areas 14 corresponding to a plurality of horizontal passages through which the first game content can move, and one or more second areas 15 corresponding to one or more vertical passages are defined. As described below, the first areas 14 and the second areas 15 projected onto the field object are defined as the horizontal passages and the vertical passages, respectively.

The storage unit 11 also stores correspondence information that associates the second object with the texture coordinates of the field image. The correspondence information is used by the control unit 13 that executes a process of placing the second game content on the field object, as described below.

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 with, for example, a touch panel, and functions as an interface that detects various user operations.

For example, the display unit 12 can detect a tap operation, a long tap operation, a flick operation, a swipe operation, and the like of the user. 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 finger on the display unit 12 without moving it. The flick operation is an operation in which the user touches the display unit 12 with a finger and releases the finger while moving the finger while keeping the finger on the display unit 12. The swipe operation is an operation in which the user touches the display unit 12 with a finger and holds the finger movable while keeping the finger on the display unit 12. Preferably, the display unit 12 can detect the above-mentioned operations (e.g., a multi-tap operation, etc.) performed by the user using multiple fingers.

The control unit 13 is a dedicated microprocessor or a CPU that realizes a specific function by loading a specific program. The control unit 13 controls the operation of the entire information processing device 10. For example, the control unit 13 executes a game application in response to a user operation on the display unit 12. The control unit 13 also 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 a field object, a first object, etc. are displayed. In addition, the control unit 13 causes the first object to move 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. 3. The field object 16 is composed of a large number of object elements (for example, a polygonal planar mesh). An object coordinate system having mutually orthogonal Xo, Yo, and Zo axes is set in the field object 16. In this embodiment, the field object 16 has a cross-sectional shape in any plane approximately parallel to the Yo-Zo plane extended in the Xo axis direction, and is, for example, a sheet-like object with substantially no thickness. In this specification, the cross-sectional shape of an object includes a cross-sectional shape of an object with substantially no thickness, for example, a shape related to a straight line, a curve, or a combination of these. In addition, the shape in which the cross-sectional shape is extended may be, for example, the cross-sectional shape of the field object 1 after the cross-sectional shape is extended.
3 after an uneven shape corresponding to a virtual "mountain" or "valley" is formed on the field object 16 shown in FIG.
The shape of the field object 16 after deleting some object elements or the shape of the field object 16 after deleting some object elements is included in the "shape with an extended cross-sectional shape".
has a first portion 17 and a second portion 18 .

In this embodiment, the first portion 17 has a substantially planar shape and is provided on the Xo-Yo plane. The shape of the first portion 17 is not limited to a planar shape, and may be, for example, a shape in which the cross-sectional shape of the first portion 17 in any plane substantially parallel to the Yo-Zo plane has any curvature.
In this case, the first portion 17 is provided so that, for example, the end portion in the −Yo direction of the first portion 17 is positioned on the Xo-Yo plane.

The second portion 18 extends from an end portion of the first portion 17 in, for example, the −Yo direction.
The second portion 18 is a portion (inclined portion) inclined toward one side of the Yo plane (for example, the +Zo side). In this embodiment, the second portion 18 is configured by a combination of a plurality of object elements, but may be configured as a substantially curved surface, for example, by making the size of each object element sufficiently small. Alternatively, each object element constituting the second portion 18 may be a curved surface.

Here, the control unit 13 projects the field image onto the field object 16. The projection of the field image is performed by, for example, texture mapping. Specifically, the control unit 13 maps points (texture coordinates) on the field image onto a large number of vertices (object coordinates) on the field object 16, respectively, and projects the field image onto the field object 16. Here, the vertices refer to, for example, vertices 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.
A first area 14 and a second area 15 on the field image projected onto the screen 6 are respectively defined as horizontal passages 19 and vertical passages 20 through which the first game medium can move. In this embodiment, as shown in FIG. 3 for example, a plurality of horizontal passages 19 are provided extending substantially parallel to the Xo axis of the object coordinate system. In addition, a plurality of vertical passages 20 are provided extending between two horizontal passages 19 to connect the two horizontal passages 19. Preferably, the longitudinal length of the horizontal passage 19 (for example, the length in the Xo axis direction)
is longer than the longitudinal length of the vertical passage 20 (e.g., the length in the Yo axis direction).

Next, the control unit 13 places the field object 16 in the three-dimensional virtual space, for example, as shown in FIG. 4. For the sake of simplicity, in FIG. 4, the field object 16 is placed in the three-dimensional virtual space.
Although only six vertices A to F corresponding to the number 6 are illustrated, any number of vertices may be set. Here, in the virtual space, there are an Xw axis (first axis), a Yw axis (second axis), and
A world coordinate system having Zw-axes is set. The control unit 13 places the field object 16 in the virtual space so that, for example, the Xo-axis and Yo-axis of the field object 16 coincide with the Xw-axis and Yw-axis of the virtual space, respectively. Therefore, the second part 18 (object elements CD, DE, and EF in FIG. 4) of the field object 16 placed in the virtual space is located on one side of the Xw-Yw plane of the virtual space (for example, +
Zw side).

Next, the control unit 13 places a virtual camera 21 in the virtual space. The virtual camera 21 is used in the process of generating a field screen, as described below. In this embodiment, the virtual camera 21 is placed on the other side (for example, the -Zw side) of the Xw-Yw plane of the virtual space so that the optical axis 22 of the virtual camera 21 is approximately parallel to the Yw-Zw plane. In this case, the second portion 18 of the field object 16 becomes more distant from the virtual camera 21 in the direction of the optical axis 22.
It is tilted downward when viewed from the virtual camera 21. Preferably, the virtual camera 21 is positioned so that the optical axis 22 intersects with the field object.

Next, the control unit 13 controls the first object 23 onto which the image of the first game medium is projected,
A second object 24 onto which an image of the game medium is projected, and a background object 25 onto which a background image is projected are each placed in a virtual space.

The first object 23 is placed at an arbitrary position on the field object 16 within the field of view 26 of the virtual camera 21. In this embodiment, the first object 23 is
The first object 23 is disposed on the first portion 17 of the field object 16.
The first object 23 is, for example, a planar object with no thickness. The first object 23 is aligned 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,
2).

The second object 24 is placed at a predetermined position on the field object 16. Specifically, the control unit 13 reads out correspondence information that associates the second object 24 with the texture coordinates of the field image from the storage unit 11. Next, the control unit 13 places the second object 24 at a position (object coordinates) on the field object 16 that corresponds to the texture coordinates associated with the second object 24 based on the correspondence information. The object coordinates of the field object 16 that correspond to the texture coordinates associated with the second object 24 are uniquely determined by the above-mentioned texture mapping. In this embodiment, the second object 24 is, for example, an object with a planar shape that has no thickness. The second object 24 is placed so that the projection surface of the image satisfies a predetermined condition with respect to the optical axis 22 of the virtual camera 21 (for example, so that it is approximately perpendicular to the optical axis 22).

The background object 25 is placed in the virtual space so that at least a part of the background object 25 is included in the field of view 26 of the virtual camera 21. In this embodiment, the background object 25 is placed so as to be in contact with an 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 placed in the virtual space so that at least a part of the background object 25 is included in the field object 16.
For example, the background object 25 is a planar object with no thickness. The background object 25 is disposed so that the projection surface of the image satisfies a predetermined condition with respect to the optical axis 22 of the virtual camera 21 (for example, so as to be approximately perpendicular to the optical axis 22).

Next, the control unit 13 causes the display unit 12 to display a field screen in which the virtual space is viewed from the viewpoint of the virtual camera 21. For example, as shown in Fig. 5, a screen coordinate system including an x-axis (third axis) and a y-axis (fourth axis) perpendicular to each other is set on the field screen. In this embodiment, the x-axis direction is the longitudinal direction of the field screen (for example, the left-right direction in Fig. 5).
, and the y-axis direction substantially coincides with the short-side direction of the field screen (for example, the up-down direction in FIG. 5). Also, the x-axis direction of the field screen substantially coincides with the Xw-axis direction of the virtual space.

The field of view 26 of the virtual camera 21 arranged as described above may include 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, as shown in Fig. 4. In this case, the field screen displayed on the display unit 12 may include a field area 27, as shown in Fig. 5.
and a background region 28.

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

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

Also, a first object 23 is displayed on the field screen. In Fig. 5, two first objects 23 are shown on the side passage 19a, but any number of first objects 23 may be present. 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.

Also displayed on the field screen are all the second objects 24 contained within the field of view 26 of the virtual camera 21. In Fig. 5, one second object 24 (a building) is shown.

As described above, the first object 23, the second object 24, and the background object 25 are each a planar object, and are disposed approximately 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 approximately parallel to the field screen (i.e., the projection surfaces of the objects face the direction of the screen) (see FIG. 5).

Next, the control unit 13 moves the first object 23 on the field object 16 relatively to the field object 16 in response to 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 this embodiment, the control unit 13 moves the first object 23 relative to the field object 16 by moving the field object 16 (i.e., changing the world coordinates of the field object 16) without substantially moving the first object 23 (i.e., without substantially changing the world coordinates of the first object 23).

Here, the display unit 12 provided in the information processing device 10 generally has a longitudinal direction (e.g., left-right direction) and a lateral direction (e.g., up-down direction), and the field screen in this embodiment has a longitudinal direction and a lateral direction as described above in accordance with the shape of the display unit 12. Therefore, on the field screen, a relatively long (large) operation area exists in the longitudinal direction, and a relatively short (small) operation area exists in the lateral direction.

As described later, the control unit 13 moves the first object 23 in a direction substantially parallel to the Xw-Zw plane of the first object 23 based on information obtained in a relatively long operation area in the longitudinal direction of the field screen among information obtained in response to the first user operation. On the other hand, the control unit 13 moves the first object 23 in a direction substantially parallel to the Xw-Zw plane of the first object 23 based on information obtained in a relatively short operation area in the lateral 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 -Zw plane.

Hereinafter, the operation of the control unit 13 for moving the first object 23 on the field object 16 relatively to the field object 16 will be specifically described.

First, the first object 2 is moved in a direction substantially parallel to the Xw-Zw plane (first plane) in the virtual space.
The following describes the operation of the control unit 13 that moves the first object 23 relative to the field object 16. In this embodiment, the first object 23 moves in the Xw-axis direction in the virtual space relative to the field object 16. Here, movement in the Xw-axis direction means that the Xw-axis component of the moving speed of the first object 23 is greater than zero.

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

In this 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 specified by the swipe operation. The screen coordinates of the second position are screen coordinates corresponding to the position on the field screen that is currently specified by the swipe operation. Therefore, in this embodiment, the screen coordinates of the second position may change from time to time in response to the first user operation. The first user operation is not limited to a swipe operation, and may be any operation that specifies 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 (multiple long tap operation). In such a case, the screen coordinates of both the first position and the second position may change from time to time in response to the first user operation. Hereinafter, the position vector of the second position with the first position as the reference point is also referred to as the first input vector.

Next, the control unit 13 determines the moving speed of the first object 23 along the Xw axis according to the x-axis component of the length between the first position and the second position (i.e., the absolute value of the x-axis component of the first input vector). In this embodiment, the longer the x-axis 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 stepwise according to the x-axis component of the length between the first position and the second position. Here, the mode in which the moving speed changes continuously may include a mode in which the range of the axial component of the moving speed corresponding to each step is sufficiently small among the modes in which the moving speed changes stepwise.

Next, the control unit 13 determines the moving direction of the first object 23 to be the +Xw direction or the -Xw direction of the world coordinate system depending on whether the value obtained by subtracting the x-coordinate of the second position from the x-coordinate of the first position is positive or negative (i.e., the direction of the x-axis component of the first input vector). Then, the control unit 13 moves the first object 23 relatively to the field object 16 in the determined direction at the determined moving speed.

In this embodiment, when the direction of the x-axis component of the first input vector is the +x direction,
The control unit 13 determines the moving direction of the first object 23 to be 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.
When the direction of the x-axis direction component of the first input vector is the -x direction, the control unit 13 determines the movement direction of the first object 23 to be 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, the operation of the control unit 13 described above will be specifically described with reference to Figs. 5 to 7. For example, the control unit 13 detects the first position and the second position while the first user operation is detected in a state in which the field screen shown in Fig. 5 is displayed on the display unit 12. For example, as shown in Fig. 6, when the second position 30 is located in the upper left on 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, as shown in Fig. 7, for example, the field object 16 and the background object 25 displayed in the field area 27 and the background area 28, respectively, move in a flowing manner toward the right direction (+x direction) of the screen without substantially changing the position (screen coordinates) of the first object 23.

Preferably, when the control unit 13 detects the end of the first user operation (for example, when the user performing the swipe operation removes his/her finger from the display unit 12), the control unit 13 moves the first object 23 in the Xw axis direction while changing the moving speed of the first object 23. In this embodiment, in response to detection of the end of the first user operation, 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. With this configuration, even if the user removes his/her finger from the display unit 12, the first object 23 moves in the Xw axis direction while decelerating.
Since the first object 23 continues to move in the axial direction, the operational burden on the user attempting to move the first object 23 a relatively long distance along the lateral passage 19 is reduced, improving the operability of the game.

Here, the time rate of change 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 rate of change according to the moving speed of the first object 23 so that the faster the moving speed of the first object 23 is, the greater or smaller the time rate of change becomes. In addition, for example, a predetermined parameter indicating a characteristic of the first game medium, such as weight or agility, is set for the first object 23, and the control unit 13 may calculate the time rate of change according to the parameter so that the greater the parameter is, the greater the time rate of change of the moving speed of the first object 23 is. In addition, for example, a predetermined parameter indicating the state of the ground, such as asphalt or mud, is set for a partial area on the field object 16, and the control unit 13 may calculate the time rate of change according to the parameter.
The rate of change over time of the moving speed of the object 23 may also 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 control unit 13 sets the moving speed of the first object 23 to a predetermined value. In this embodiment, the control unit 13 sets the moving speed of the first object 23 to zero in response to the detection of the second user operation. Here, the second user operation is, for example, a tap operation performed at an arbitrary position on the field screen, but may be any user operation such as a multi-tap operation.
With this configuration, the user can change the movement speed of the first object 23, which moves in the Xw axis direction while changing its movement speed as described above, to a predetermined value at any timing (for example, to stop the first object 23), thereby improving the operability of the game.

Next, the first object 2 is moved in a direction substantially parallel to the Yw-Zw plane (second plane) in the virtual space.
The following describes the operation of the control unit 13 that moves the first object 23 relative to the field object 16. In this embodiment, the first object 23 moves in the Yw-axis direction in the virtual space relative to the field object 16. Here, movement in the Yw-axis direction means that the Yw-axis component of the moving speed of the first object 23 is greater than zero.

First, the control unit 13 determines whether or not the first object 23 is located within a predetermined area 32 near the vertical passage 20. If it is determined that the first object 23 is located within the area 32, the control unit 13 determines whether or not a predetermined condition (first condition) regarding a change in the second position in response to the detected first user operation is satisfied.

In this embodiment, the first condition is a condition that the absolute value of a y-axis component of a length between the second position before the change and the second position after the change, i.e., a y-axis component of a position vector (second input vector) of the second position after the change with the second position before the change as a reference point, is equal to or greater than a predetermined threshold value; or
The condition includes that the absolute value of the y-axis component of the speed of change of the second position that changes in response to the first user operation (i.e., the magnitude of the y-axis component of the speed vector of the second position) is greater than or equal to a predetermined threshold value.

Preferably, the first condition is that the vertical passage 20 corresponding to the above-mentioned area 32 is located within the first object 2
3 (for example, when the vertical passage 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 (i.e., the direction of the y-axis direction component of the second input vector is the -y direction).
The condition further includes that when the object 23 is located in the +Yw direction (for example, when the vertical passage 20 extends toward the front 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 positive (i.e., the direction of the y-axis component of the second input vector is in the +y direction).

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 by a predetermined distance in the virtual space in a direction substantially parallel to the Yw-Zw plane of the virtual space. 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, among the multiple vertices on the field object 16, the vertices existing on a plane substantially parallel to the Yw-Zw plane move along a predetermined trajectory on the plane. Here, the shape of the predetermined trajectory is substantially identical to a 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 the plane substantially parallel to the Yw-Zw plane slides along the cross-sectional shape of the field object 16. 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 of the vertical passage 20 in the longitudinal direction (in this embodiment, the Yw axis direction).

Preferably, the control unit 13 adjusts the projection planes of the images of the first object 23, the second object 24, and the background object 25 so as to satisfy the above-mentioned condition with respect to the optical axis 22 of the virtual camera 21 during the sliding movement of the field object 16 (for example,
Specifically, the control unit 13 controls the first object 23 to be approximately perpendicular to the optical axis 22 while sliding the field object 16, for example, by changing the angle between the first object 23 and the field object 16.
The projection plane is controlled so as to be approximately perpendicular to the optical axis 22. With this configuration, even when the field object 16 is slid,
Since the first object 23, the second object 24, and the background object 25 are displayed substantially parallel to the field screen (i.e., the projection plane of the objects faces the direction of the screen),
Improves visibility of the field screen.

7 to 11, the operation of the control unit 13 will be specifically described. For example, when the field screen shown in FIG.
A change in the second position in response to a first user operation is detected. Here, the first object 23 is located within 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. As shown in Fig. 9, the second position 33 after the change is located in the upper left on the field screen with respect to the second position 30 before the change, and the above-mentioned first condition regarding the change in the second position is satisfied.

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

The control unit 13 also 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 (a first specific area and a second specific area) that are continuous (adjacent) in the Xo axis direction (which is the same as the Xw axis direction in this embodiment). The first object 23 can move seamlessly between the first specific area and the second specific area (for example, without the display of the field screen switching or going dark). 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, the control unit 1
3 is a diagram showing a case where, when the first object 23 exists in the first specific area, for example, the first object 23 (user character) and the second object 24 (for example, an NPC who is a resident of the town)
On the other hand, when the first object 23 is present in the second specific area, the control unit 13 executes a process such as a battle between the first object 23 (user character) and an enemy character. Also, for example, the control unit 13 may select different music data (
BGM) may be played.

Next, the operation of the information processing device 10 will be described with reference to the flowchart shown in Fig. 12. This operation is performed, for example, while the first game part is being executed, with the field screen being displayed.

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. If the first user operation is detected (step S100-Yes), the control unit 13 proceeds to step S101.

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

Step S102: The control unit 13 then detects a second position on the field screen corresponding 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: Next, the control unit 13 calculates Xw-Z based on the first position and the second position.
A process of moving the first object 23 in a direction substantially parallel to the w-plane is executed. The details of this process will be described later.

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

Step S105: The control unit 13 then determines whether or not the end of the first user operation has been detected. If it is determined that the end of the first user operation has been detected (Step S105-Yes),
), the process proceeds to step S106. On the other hand, if 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: If it is determined in step S105 that the end of the first user operation has been detected (step S105-Yes), the control unit 13 moves the first object 23 in the Xw-axis direction while changing (e.g., decelerating) the movement speed of the first object 23.

Step S107: Next, the control unit 13 judges whether or not a second user operation has been detected. The second user operation is, for example, a tap operation performed at an arbitrary position on the field screen. If it is judged that the second user operation has been detected (step S107-Yes), the process proceeds to step S108. On the other hand, if it is judged that the second user operation has not been detected (step S
107-No), proceed to step S109.

Step S108: If 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: If it is determined in step S107 that the second user operation has not been detected (step S107-No), or after step S108, the control unit 13 determines whether or not the first user operation has been newly detected. If it is determined that the first user operation has been newly detected (step S109-Yes), the process returns to step S101. On the other hand, if it is determined that the first user operation has not been newly detected (step S109-No), the process returns to step S101.
Return to 6.

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

Step S200: First, the control unit 13 determines a first position and a second position in response to a first user operation.
Based on the position, the control unit 13 determines the moving speed and moving direction of the first object 23. Specifically, the control unit 13 determines the moving speed of the first object 23 according to the x-axis component of the length between the first position and the second position (the absolute value of the x-axis component of the first input vector). Furthermore, the control unit 13 determines the moving direction of the first object 23 to be the +Xw direction or the -Xw direction according to the positive or negative value 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 component of the first input vector).

Step S201: The control unit 13 then 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, the process proceeds to step S104 described above (see FIG. 12).

Next, the above-mentioned movement process in a direction substantially parallel to the Yw-Zw plane (step S105) will be described in detail 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 within a predetermined area 32 near the vertical passage 20. If it is determined that the first object 23 is located within the area 32 (step S300-Yes), the process proceeds to step S301. On the other hand, if it is determined that the first object 23 is not located within the area 32 (step S300
--No), proceed to step S105 described above (see FIG. 12).

Step S301: If it is determined in step S300 that the first object 23 is located within the area 32 (step S300-Yes), the control unit 13 determines whether or not the above-mentioned first condition regarding the change in the second position in response to the first user operation is satisfied. If it is determined that the first condition is satisfied (step S301-Yes), the process proceeds to step S302. On the other hand, if it is determined that the first condition is not satisfied (step S301-No), the process proceeds to the above-mentioned step S105 (see FIG. 12).

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

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

For example, the dimensions of a display device installed in a smartphone or the like differ in the left-right and top-bottom directions.
Generally, the screen size is relatively small. For this reason, for example, a field screen in which a flat field is viewed from above can only display the field within a relatively small display area in the short side direction of the screen. On the other hand, according to the above-mentioned information processing device 10, at least a part of the inclined portion of the field object 16 is displayed on the field screen as a field that spreads in the depth direction. In other words, at least a part of the inclined portion is displayed distorted (compressed) in the short side direction of the field screen, so that the range of the field that is displayed on the screen at one time is expanded, and the visibility of the field screen is improved. In addition, the field object 16 is
The shape extends in the longitudinal direction (left and right direction) on the field screen, which reduces distortion of the field object 16 displayed on the field screen in the longitudinal direction of the screen, improving the visibility of the field screen.

Furthermore, when the information processing device 10 moves the first object 23 in a direction substantially parallel to the Xw-Zw plane (second plane), the information processing device 10 translates the field object 16 in the Xw axis (first axis) direction. Furthermore, when the information processing device 10 moves the first object 23 in a direction substantially parallel to the Yw-Zw plane (first plane), the information processing device 10 moves the field object 16 in a direction substantially parallel to the Yw-Zw plane in a manner different from the translation. With this 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 depth direction of the field on the field screen can be displayed, so that the visibility of the field screen is improved, for example, compared to a configuration in which the screen is scrolled and displayed in both the left-right direction and the up-down direction.

Furthermore, the information processing device 10 controls the image projection plane of the first object 23 and the second object 24 to 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 on the field screen approximately parallel to the field screen, further improving the visibility of the field screen.

Further, the field object 16 has a first portion 17 and a second portion 18 extending from an end of the first portion 17. With this configuration, for example, the field is displayed relatively large on the front side of the field screen, while on the back side the field is compressed in the vertical direction by the second portion 18, so that a field screen suitable for the display unit 12 having a limited display area can be realized.

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

Moreover, the information processing device 10 according to this embodiment detects the first position and the second position while the first user operation is being detected. Furthermore, the information processing device 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 moves the first object 23 in a direction substantially parallel to the Yw-Zw plane (second plane) in response to a change in the second position. In this manner, among 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 a user wants to move the first object 23 in a direction substantially parallel to the first plane, the first object 23 may move in a direction substantially parallel to the first plane due to a slight positional shift of the first user operation, etc.
This prevents the first object 23 from moving in a direction unintended by the user, such as the first object 23 moving in a direction substantially parallel to the second plane, thereby improving the operability of the game.

Furthermore, when the information processing device 10 detects the end of the first user operation,
With this configuration, the first object 23 moves in the Xw-axis direction while changing (e.g., decelerating) the moving speed of the first object 23.
Since the first object 23 continues to move in the Xw-axis direction while decelerating, the operational burden on the user attempting to move the first object 23 a relatively long distance along the side passage 19 is reduced, further improving the operability of the game.

Furthermore, when the information processing device 10 detects a 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 device 10 sets the moving speed of the first object 23 to a predetermined value (e.g., zero). With this configuration, the user can change the moving speed of the first object 23, which moves in the Xw axis direction while changing the moving speed as described above, to a predetermined value at any timing (e.g., stop the first object 23), further improving the operability of the game.

Although the present invention has been described based on the drawings and embodiments, 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 modifications and corrections are included in the scope of the present invention. For example, the functions included in each means, each step, etc. can be rearranged so as not to be logically inconsistent, and multiple means, steps, etc. can be combined into one 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, if the speed of change of the second position (i.e., the magnitude of the velocity vector of the second position) is equal to or greater than a predetermined threshold, the control unit 13
The moving speed of the object 23 may be set to a predetermined value (e.g., zero) to determine that the end of the first user operation has been detected. With this configuration, the user performing the first user operation may, for example, move the first object 23 in the Xw-axis direction at a relatively high speed while the display unit 12
The speed of the first object 23 can be changed to a predetermined value by a simple operation of quickly moving a finger touching the first object 23. This further improves the operability of the game.

Alternatively, when the rate of change of the second position is equal to or greater than a predetermined threshold, the control unit 13 may cause the first object 23 to perform an operation other than movement, for example, a predetermined action such as jumping. With this configuration, for example, when an obstacle (game medium) such as a rock or a pitfall is present on the side passage 19, the user performing the first user operation can cause the first object 23 to jump over the obstacle without terminating the first user operation (for example, without removing the finger from the display unit 12). This further improves the operability of the game and creates an action-like nature of the game, thereby increasing the interest of the game.

For example, when the control unit 13 moves the first object 23 in the Yw-axis direction while a first user operation is being detected (i.e., without detecting the end of the first user), the control unit 13 may automatically update the screen coordinates of the first position detected in response to the detection of the first user operation from the screen coordinates of the position on the field screen initially specified by, for example, a swipe operation to other screen coordinates.

Specifically, while the control unit 13 is moving the first object 23 in the Yw-axis direction in a state where the first user operation is detected (for example, in a state where the field screen shown in FIG. 10 is displayed on the display unit 12), when the control unit 13 detects a change in the second position in response to the first user operation,
The screen coordinates of the second position before the change are set to the screen coordinates of the new first position.

Preferably, as shown in FIG. 15A, for example, the control unit 13 determines the direction of the y-axis component of a position vector 34 of the second position 33 before the change with the first position 29 as the reference point (−y direction in the figure) and the direction of a position vector 36 of the second position 35 after the change with the second position 33 before the change as the reference point.
(i.e., the second input vector) has a different direction (+y direction in the figure), the second position 33 before the change is set to a new first position 37, as shown in FIG. 15(b).

With this configuration, for example, while the first object 23 is moving along the vertical passage 20, the user can move his/her finger only a relatively short distance while keeping the finger in contact with the display unit 12,
After the first object 23 has moved to another side passage 19b, the first object 23 is moved by the Xw
The first object 23 can be moved in any direction along the axis. Specifically, the user moves the first object 23 in the −Xw direction in the lateral passage 19a on the near side as shown in FIG.
After moving the first object 23 in the −Yw direction along the vertical passage 20 (see FIG. 10 ),
When moving the first object 23 in the +Xw direction in another side passage 19b (see FIG. 11), for example, in FIG. 15(a), there is no need to move the finger to the +x side beyond the first position 29. Therefore, the complexity of the user's movement operation is reduced.

In the above embodiment, the first determination regarding the change in the second position in response to the first user operation is performed.
Although a configuration has been described in which the first object 23 is moved relative to the field object 16 in a direction approximately parallel to the Yw-Zw plane in the virtual space depending on whether or not a condition is satisfied, the first object 23 may also be moved in a direction approximately parallel to the Yw-Zw plane in the virtual space based on both the first position and the second position corresponding to the first user operation.

Specifically, the control unit 13 first determines whether or not the first object 23 is located within a predetermined area 32 near the vertical passage 20. If it is determined that the first object 23 is located within the area 32, the control unit 13 detects a first user operation, and a first position and a second position corresponding to the first user operation. Next, the control unit 13 calculates Yw-Z according to the y-axis component of the length between the first position and the second position (i.e., the absolute value of the y-axis component of the first input vector).
The moving speed of the first object 23 in a direction substantially parallel to the w-plane is determined. For example, the longer the y-axis component of the length between the first position and the second position, the greater the moving speed of the first object 23 in a direction substantially parallel to the Yw-Zw plane. Here, when moving the first object 23 at the determined moving speed, the first object 23 may be accelerated with the determined moving speed as an upper limit. The moving speed of the first object 23 in a direction substantially parallel to the Yw-Zw plane may change continuously or stepwise depending on the y-axis component of the length between the first position and the second position.

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

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

Here, as described above, the display unit 12 has a longitudinal direction (e.g., left-right direction) and a lateral direction (e.g., up-down direction), so the length (size) of the operation area on the screen is different between the longitudinal direction and the lateral direction. Here, the detection pitch of the touch panel is generally equal in the lateral direction and the vertical direction. Therefore, the number of points at which user operations can be detected in the lateral direction of the screen is smaller than the number of points at which user operations can be detected in the longitudinal direction of the screen. For this reason, for example, in a configuration in which the algorithm for determining the moving speed Xw of the first object 23 and the algorithm for determining the moving speed Yw are the same, the operability of the game is lower in the lateral direction of the operation area compared to the longitudinal direction of the operation area. In contrast, 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, so that the length (size) of the longitudinal direction of the operation area on the field screen as described above
In a configuration in which the length (size) of the operation area in the short side direction is different from the length (size) of the operation area in the short side direction, the operability of the game in the operation area in the short side direction can be further improved.

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

Specifically, in a configuration in which the moving speed Xw and the moving speed Yw of the first object 23 change continuously depending on the x-axis component and the y-axis component of the length between the first position and the second position, the moving speed Xw with respect to the x-axis component of the length between the first position and the second position is
The rate of change in the moving speed Yw with respect to the y-axis direction component of the length between the first position and the second position is smaller or larger than the rate of change in the moving speed Yw with respect to the y-axis direction component of the length between the first position and the second position.

More specifically, in a configuration in which the moving speed Xw and the moving speed Yw of the first object 23 change in stages according to the x-axis component and the y-axis component of the length between the first position and the second position, 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 determines, as the moving speed Xw, the speed value of the stage according to the x-axis component of the length between the first position and the second position, among n stages (2<n) of speed values. Also, the control unit 13
Of the m stages (1<m<n) of velocity values, the velocity value corresponding to the stage according to the y-axis component of the length between the first position and the second position is set as the moving velocity Yw. Here, the velocity values corresponding to each stage may be set at equal intervals (e.g., 0, 5, 10, ...) or may be set at different intervals (e.g., 0, 1, 5, 15, ...). In addition, the range of the axial component of the moving velocity corresponding to each stage may be set to the same size (e.g., 5 pixels) or may be set to different sizes (e.g., 5 pixels or 10 pixels).

In the above embodiment, in response to the end of the first user operation, the first object 2
In the above description, the control unit 13 changes the moving speed Xw of the first object 23, but the moving speed Yw may be changed in a similar manner. Specifically, when the control unit 13 detects 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 embodiment, the first object 23 is a field object 16.
, without substantially moving the first object 23,
Although the configuration for moving the field object 16 has been described, for example, the configuration may be such that the first object 23 is moved without substantially moving the field object 16. In such a configuration, the control unit 13 moves the virtual camera 21 in response 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 embodiment, the field object 16 arranged in a three-dimensional virtual space is used as the field (ground), but a two-dimensional virtual space may be used instead. In this case, the field, the first game medium, the second game medium, the background, etc. are all configured as two-dimensional images.

Furthermore, although the games in the above-mentioned embodiments have been described as role-playing games or simulation games, the present invention is applicable to games of various genres in which game media is moved around a field within the game.

The information processing device 10 may be capable of communicating with a server device via, for example, the Internet. In such a configuration, when the first object 23 moves to a predetermined position on the field (for example, an entrance to a cave or a building), the information processing device 10 acquires another field image (for example, an image of a field showing the inside of a cave or a building) from the server device. Then, the information processing device 10 performs the following operations on the other field image received from the server device:
The first object 23 and the like are projected onto another newly generated (defined) field object, and placed on the other field object. With this configuration, the variety of fields is increased and the interest of the game is improved, compared to a configuration in which only the field image stored in the information processing device 10 itself is used.

In the above embodiment, the field object 16 has a configuration including the first portion 17 and the second portion 18, but the shape of the field object 16 is not limited to this. The field object 160 according to the modified embodiment has a cylindrical shape extending in the Xo axis direction in the object coordinate system, and in the same manner as in the above embodiment, when placed in the virtual space, the field object 160 becomes smaller in size as it moves away from the virtual camera 21 in the direction of the optical axis 22.
Specifically, the field object 160 has a slope that slopes downward when viewed from the side of the field object 160.
is a square cylindrical shape or a substantially cylindrical shape that is rotationally symmetrical with respect to the Xo axis, or a square cylindrical shape or a substantially elliptical cylindrical shape that is rotationally asymmetrical with respect to the Xo axis. For example, Fig. 16 is a cross-sectional view of a field object 160 having a square cylindrical shape that is rotationally symmetrical with respect to the Xo axis, cut along a plane substantially parallel to the Yw-Zw plane, in a state in which the field object 160 is placed in a virtual space in the same manner as in the above-described embodiment. In Fig. 16, for example, object elements CD, DE, etc. correspond to the inclined portion.

In a configuration in which such a field object 160 is employed, when it is determined that the above-mentioned first condition is satisfied, the control unit 13 moves the first object 23 toward the field object 160 in a direction substantially parallel to the Yw-Zw plane of the virtual space by a predetermined distance in the virtual space.
60. 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, among the multiple vertices on the field object 16, each vertex existing on a plane parallel to the Yw-Zw plane is
It moves on the surface along a concentric circular trajectory centered on the Xw axis.

In the above-described embodiment, a part of the various game screens may be displayed as a web display on the information processing device 10 based on data generated by a server device capable of communicating with the information processing device 10, and a part of the game screen (for example, a header area and a footer area in which menu buttons are arranged) may be displayed as a native display by a native application installed on the information processing device 10. In this way, the game according to the above-described embodiment is
It may also be a hybrid game in which the information processing device 10 and the server device each handle part of the processing.

Furthermore, a device capable of executing information processing, such as a computer or a mobile phone, can be suitably used to function as the information processing device 10 according to the above-described embodiment. Such a device can be realized by storing a program describing the processing contents for realizing each function of the information processing device 10 according to the embodiment in a storage unit of the device, and reading and executing the program by a CPU of the device.
