Description

  The present invention relates to an information processing program and an information processing method.

Conventionally, in a stationary game apparatus, a controller for a real object is provided separately from the game apparatus main body as an operation tool.
Such a controller for a real object is not suitable as an operation application for a game executed on a mobile terminal such as a smartphone. For this reason, the virtual controller displayed on the touch panel of the said portable terminal is used for operation of the game performed with a portable terminal (for example, refer patent document 1).

However, in recent years, games using three-dimensional objects arranged in a virtual three-dimensional space (hereinafter referred to as “3D games”) have become very popular. There is a demand for a virtual controller suitable for such a 3D game.
In order to meet this requirement, at least the virtual controller needs to have a three-dimensional shape. However, since the virtual controller realized by the conventional technique including Patent Document 1 is only represented by an image on a two-dimensional plane, it cannot meet the request.

  The present invention has been made in view of such circumstances, and an object thereof is to realize a virtual controller suitable for a 3D game.

The control process including is executed.

  An information processing method corresponding to the information processing program of one embodiment of the present invention is also provided as an information processing method of one embodiment of the present invention.

  According to the present invention, a virtual controller suitable for a 3D game can be realized.

It is a block diagram which shows an example of the hardware constitutions of the player terminal which concerns on one Embodiment of this invention. 3 shows an example of a 3D game execution screen displayed on the player terminal of FIG. 1. It is a functional block diagram which shows an example of a functional structure of the player terminal of FIG. It is a flowchart explaining an example of the flow of the game display process which the player terminal of FIG. 1 performs. It is a figure which shows the various specific examples of the object to which this invention is applied.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the following description, when simply referred to as “image”, both “moving image” and “still image” are included.
The “moving image” includes an image displayed by each of the following first to third processes.
The first process refers to a process in which a series of still images composed of a plurality of images are continuously switched over time and displayed for each motion of an object (for example, a game character) in a planar image (2D image). Specifically, for example, two-dimensional animation, so-called flip-flopping processing, corresponds to the first processing.
The second process refers to a process in which motions corresponding to respective actions of an object (for example, a game character) in a stereoscopic image (3D model image) are set, and the motions are changed and displayed over time. Specifically, for example, a three-dimensional animation corresponds to the second process.
The third process refers to a process in which videos (that is, moving images) corresponding to respective actions of an object (for example, a game character) are prepared and the video is played over time.

  FIG. 1 is a block diagram showing a hardware configuration of a player terminal 1 according to an embodiment of the present invention.

The player terminal 1 is composed of a smartphone or the like.
The player terminal 1 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, a bus 24, an input / output interface 25, a touch operation input unit 26, a display Unit 27, input unit 28, storage unit 29, communication unit 30, and drive 31.

The CPU 21 executes various processes according to a program recorded in the ROM 22 or a program loaded from the storage unit 29 to the RAM 23.
The RAM 23 appropriately stores data necessary for the CPU 21 to execute various processes.

  The CPU 21, ROM 22, and RAM 23 are connected to each other via a bus 24. An input / output interface 25 is also connected to the bus 24. A touch operation input unit 26, a display unit 27, an input unit 28, a storage unit 29, a communication unit 30, and a drive 31 are connected to the input / output interface 25.

The touch operation input unit 26 includes, for example, a capacitance type or resistance film type (pressure sensitive) position input sensor stacked on the display unit 27, and detects the coordinates of the position where the touch operation is performed.
Here, the touch operation refers to an operation of touching or approaching an object with respect to the touch operation input unit 26. The object that contacts or approaches the touch operation input unit 26 is, for example, a player's finger or a touch pen. Hereinafter, the position where the touch operation is performed is referred to as “touch position”, and the coordinates of the touch position are referred to as “touch coordinates”.
The display unit 27 includes a display such as a liquid crystal display, and displays various images such as an image related to a game.
Thus, in this embodiment, the touch operation input unit 26 and the display unit 27 constitute a touch panel.
In addition, when calling it a "display medium" in this specification, the display part 27 is not simply meant but the "touch panel" comprised from the touch operation input part 26 and the display part 27 is meant.

Here, swipes and flicks exist as types of touch operations on the touch panel, for example.
However, both the swipe and the flick are the second state in which the contact or proximity of the display medium is maintained and the position of the object is changed from the first state in which the contact or proximity of the object to the display medium is started (the touch position is changed). The second state) is a series of operations from the third state where the contact or proximity of the object to the display medium is released to the third state (the third state where the object is separated from the display medium). Therefore, in this specification, such a series of operations will be collectively referred to as “swipe”.
In other words, the “swipe” in the present specification is a broad concept including the above-described flicks in addition to the commonly called swipe.

The input unit 28 is configured with various hardware buttons and the like, and inputs various information according to the player's instruction operation.
The storage unit 29 is configured by a DRAM (Dynamic Random Access Memory) or the like and stores various data.
The communication unit 30 controls communication performed with another device (a server (not shown) or another player terminal (not shown)) via a network including the Internet (not shown).

  The drive 31 is provided as necessary. A removable medium 32 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 31. The program read from the removable medium 32 by the drive 31 is installed in the storage unit 29 as necessary. The removable medium 32 can also store various data stored in the storage unit 29 in the same manner as the storage unit 29.

The 3D game can be executed on the player terminal 1 by the cooperation of the various hardware and various software of the player terminal 1 shown in FIG.
For example, in the present embodiment, a 3D game in which an image as shown in FIG. 2 is displayed on the touch panel (display medium) can be executed on the player terminal 1.
That is, FIG. 2 shows an example of a 3D game execution screen 41 displayed on the player terminal 1 of FIG.

In the 3D game shown in FIG. 2, a virtual three-dimensional space (hereinafter simply referred to as “virtual space”) constructed in a predetermined global coordinate system is used as the game space.
In this embodiment, various three-dimensional objects are used in the 3D game, but each object has an individual local coordinate system, and the coordinates of each local coordinate system are converted to global coordinates. Arranged in virtual space.
In this virtual space, a virtual three-dimensional character C moves. That is, the operation target object in the 3D game is the character C.

In the present embodiment, a rotation controller RC is employed as a virtual controller for operating the movement of the character C (coordinate change in the global coordinate system in the virtual space).
The rotation controller RC is a virtual spherical object, and is displayed in a virtual space as shown in FIG.
In the rotation controller RC, one or more types relating to rotation in the local coordinate system change according to a predetermined instruction from the player. Here, the amount of change target is not particularly limited as long as it relates to rotation, but in this embodiment, the rotation amount, the rotation direction, and the rotation speed are adopted.
Also, a method of giving a predetermined instruction from the player to the rotation controller RC is not particularly limited as long as it is a touch operation, but swipe is adopted in this embodiment.

  The buttons B1 to B4 shown in FIG. 2 are software buttons for giving an instruction other than the instruction from the rotation controller RC to the character C. In the present embodiment, a tap (pressing operation of a finger or the like) is adopted as a predetermined instruction method from the player for the buttons B1 to B4.

Although not shown here, it is assumed that the rotation controller RC is not visible to the player in the initial state where the touch operation has not yet been performed.
In this initial state, when a touch operation is performed on an area other than where the buttons B1 to B4 on the touch panel are displayed, the rotation controller RC is displayed with the touch position as the center or the center of gravity on the plane. That is, for the player, it is visually recognized as if the rotation controller RC appeared at a position in the virtual space corresponding to the touch position.

  Here, when the touch position is released without substantially changing after the touch operation, that is, when the finger or the like of the player is separated from the touch panel without changing the position, it is recognized as a tap. In this case, the rotation controller RC continues to be displayed in a stationary state.

On the other hand, if the touch position changes without the player's finger or the like moving away from the touch panel and the touch operation is not released, the first touch operation is handled as the first swipe state, and the second swipe state where the touch position changes Is detected.
In this case, the rotation controller RC starts to rotate. The direction of the rotation is the change direction of the touch position detected at each predetermined time interval, that is, the swipe direction. The direction of the swipe is also given as an instruction of the moving direction for the character C, and the character C changes its direction and moves according to the instruction.
That is, the rotation controller RC rotates in the direction of the swipe by the player (touch position changing direction), and the character C moves in the direction of the swipe in the virtual space so as to interlock with the rotation controller RC.

Furthermore, in the present embodiment, the amount of rotation of the rotation controller RC changes according to the amount of change (swipe amount) of the touch position detected at each predetermined time interval, and the rotation controller RC is linked with the rotation controller RC. The amount of movement of the character C also changes.
Further, the rotation speed of the rotation controller RC changes in accordance with the change speed (swipe speed) of the touch position detected at each predetermined time interval, and the character movement speed so as to be interlocked with the rotation controller RC. Also changes.

Here, for the character C, the amount (movement direction, movement amount, movement speed, etc.) in the global coordinate system changes at least by an instruction operation (swipe). Here, “at least” is described for character C because the amount of the local coordinate system (for example, posture, angle, etc.) may change with the change of the amount in the global coordinate system. However, for the sake of convenience, the following description will be made assuming that the movement of the character C means a coordinate change in the global coordinate system.
On the other hand, as for the rotation controller RC, as described as autorotation, the amount (rotation direction, rotation amount, rotation speed, etc.) in the local coordinate system is changed by an instruction operation (swipe) to the rotation controller RC. .
That is, in the example of FIG. 2, the rotation controller RC is used as a pseudo trackball for operating the character C. That is, the player rotates the rotation controller around its center, that is, rotates by rotating the virtual controller as if it were rotating the actual trackball, and the character C is virtually linked to the rotation. It can be moved in space.

  Here, in the real world, the player often performs the operation of releasing the hand from the trackball as if playing. The actual trackball continues to rotate with some inertia even if the player's hand is released. At this time, the faster the player's hand moves, the faster the trackball rotates. However, since there is friction in the real world, the rotation speed of the trackball gradually decreases, and eventually the rotation stops.

In the present embodiment, in order to simulate the actual movement of the trackball, the swipe second state where the player's finger or the like is separated from the touch panel is changed from the swipe second state where the touch position is changed (swipe of the swipe). When the process proceeds to (END), the third state is treated as equivalent to a state in which the player's hand is released from the actual trackball.
That is, the rotation speed of the rotation controller RC is determined based on the change speed of the touch position detected at a predetermined time before the detection time of the end of the swipe. Then, the rotation controller RC rotates at the determined rotation speed. Thereafter, the rotation speed of the rotation controller RC gradually decreases, and finally the rotation stops.

In addition, about the movement instruction | indication of the character C accompanying the detection of the 3rd state (end of a swipe) of swipe, arbitrary designs are possible according to the content of 3D game.
For example, the character C may be stopped in the virtual space on the assumption that the movement instruction of the character C is canceled at the time of detection of the third state of swipe (end of swipe).
Further, for example, at the time of detecting the third state of swipe (end of swipe), the movement instruction of the character C is not canceled and the movement instruction is continued until a predetermined timing such as the end of rotation of the rotation controller RC. Good.

In summary, the player can swipe the rotation controller RC on the touch panel as if operating a real trackball.
In this case, the rotation controller RC rotates as if it were a real trackball, and the character C moves in the virtual space in conjunction with the rotation. That is, the player can experience not only the operation feeling but also the visual experience similar to the case of operating the actual trackball.

  Furthermore, the display position of the rotation controller RC on the touch panel is not particularly limited, and may be a fixed position such as various buttons B1 to B4. However, in the present embodiment, the display position of the rotation controller RC is the start position of the touch operation (the touch position in the first state of the tap operation or swipe) as described above. Accordingly, the player can easily make the rotation controller RC appear at a desired position in the touch panel by performing a touch operation on the desired position on the touch panel.

  The linkage between the rotation controller RC and the character C described above is realized by cooperation of hardware and software in the player terminal 1. In this case, the player terminal 1 can have a functional configuration shown in FIG. 3, for example.

As shown in FIG. 3, in the CPU 21 of the player terminal 1, an operation detection unit 51, a touch position holding unit 52, and a display form determination unit 53 are provided so that the rotation controller RC and the character C can be linked. The display control unit 54 functions.
As one area of the storage unit 29, a button storage unit 71, a rotation controller storage unit 72, a character storage unit 73, and a background storage unit 74 are provided.
Although not shown, it is assumed that a functional block (game execution unit) that controls the execution of the 3D game in which the rotation controller RC and the character C are linked functions in the CPU 21.

The operation detection unit 51 detects the presence or absence of a touch operation at the touch operation input unit 26 at predetermined time intervals, and detects the touch position when there is a touch operation.
The touch position holding unit 52 holds a predetermined number of touch positions including the touch position most recently detected by the operation detection unit 51.

Here, as described above, the plurality of touch positions detected at each “predetermined time interval” are used to calculate the change direction, change amount, and change speed of the touch position.
That is, the “predetermined time interval” for detecting the touch position is not particularly limited as long as these calculations are possible. However, in this embodiment, it is assumed that the touch position is detected every time a frame is displayed on the touch panel, and the “predetermined time interval” is a time interval between two frames that are displayed in succession. .
That is, in this embodiment, the change direction of the touch position is determined based on the difference between the touch position in the latest frame and the touch position in the frame immediately before the latest frame.
However, the touch position is not detected at the end of swipe, that is, when the third state is detected when the user's finger or the like is separated from the touch panel. Therefore, at the end of the swipe, it is assumed that the change speed of the touch position is obtained from the difference between the previous frame from the latest frame and the previous frame. And based on this change speed of a touch position, the autorotation speed of the above-mentioned rotation controller RC shall be determined.
That is, in the present embodiment, in consideration of such processing at the end of the swipe, touch positions for three frames (or three times) including the latest frame are held at least by the touch position holding unit 52. Yes.

  The display form determining unit 53 determines various display forms on the game execution screen displayed on the touch panel. The button display form determining unit 61, the rotation controller display form determining unit 62, and the character display form determining unit 63. And a virtual space arrangement unit 64 and a projection unit 65.

  The button display form determination unit 61 acquires each object of the buttons B1 to B4 (FIG. 2) stored in the button storage unit 71, and determines various display forms when the buttons B1 to B4 are displayed on the touch panel. .

  The rotation controller display form determination unit 62 acquires the object of the rotation controller RC stored in the rotation controller storage unit 72, and determines various display forms when the rotation controller RC is displayed on the touch panel.

  For example, when the start of the touch operation is detected, that is, when the first state of the tap operation or swipe is detected, the rotation controller display form determination unit 62 displays the touch position at the time of detection as the display of the rotation controller RC. It is determined as a position (arrangement position such as the center of gravity). Note that the display position of the rotation controller RC is managed in the global coordinate system of the virtual space in this embodiment.

For example, the rotation controller display form determination unit 62 determines the rotation amount in the local coordinate system of the rotation controller RC based on the change amount of the touch position detected at each predetermined time interval.
Specifically, in the present embodiment, two touch positions detected in the latest frame and the previous frame are held in the touch position holding unit 52. Therefore, the rotation controller display form determination unit 62 obtains the change amount of the touch position based on the difference between the two touch positions detected in the latest frame and the previous frame. Then, the rotation controller display form determination unit 62 determines the rotation amount in the local coordinate system of the rotation controller RC based on the change amount of the touch position.

For example, the rotation controller display form determination unit 62 determines the rotation direction in the local coordinate system of the rotation controller RC based on the change direction of the touch position detected at each predetermined time interval.
Specifically, in this embodiment, the rotation controller display form determination unit 62 obtains the change direction of the touch position based on the difference between the two touch positions detected in the latest frame and the previous frame. . Then, the rotation controller display form determination unit 62 determines the rotation direction in the local coordinate system of the rotation controller RC based on the change direction of the touch position.

For example, the rotation controller display form determination unit 62 determines the rotation speed of the rotation controller RC in the local coordinate system based on the change speed of the touch position detected at each predetermined time interval.
Specifically, in the present embodiment, when the swipe is in the second state, that is, when the touch position is changed, the rotation controller display form determination unit 62 is detected in each of the latest frame and the previous frame. Based on the difference between the two touch positions, the change speed of the touch position is obtained. Then, the rotation controller display form determination unit 62 determines the rotation speed of the rotation controller RC in the local coordinate system based on the change speed of the touch position.
On the other hand, when the swipe is completed, that is, when the player's finger or the like is moved away from the touch panel and the third state of the swipe is detected, the rotation controller display form determination unit 62 determines 1 from the latest frame. The change speed of the touch position is obtained based on the difference between the two touch positions detected in the immediately preceding frame and in the immediately preceding frame (the two frames before the latest frame). Then, the rotation controller display form determination unit 62 determines the rotation speed of the rotation controller RC in the local coordinate system based on the change speed of the touch position.

  The character display form determination unit 63 acquires the character object stored in the character storage unit 73, and determines various display forms when the character C is displayed on the touch panel.

  For example, the character display form determination unit 63 determines the amount of movement of the character C in the global coordinate system (the length of the movement vector in the global coordinate system) based on the change amount of the touch position detected at each predetermined time interval. To do.

Specifically, in the present embodiment, two touch positions detected in the latest frame and the previous frame are held in the touch position holding unit 52. Therefore, the character display form determination unit 63 obtains the change amount of the touch position based on the difference between the two touch positions detected in the latest frame and the previous frame.
The character display form determination unit 63 determines the movement amount of the character in the global coordinate system based on the change amount of the touch position.

  For example, the character display form determination unit 63 determines the movement direction of the character C in the global coordinate system (the direction of the movement vector in the global coordinate system) based on the change direction of the touch position detected at each predetermined time interval. .

Specifically, in the present embodiment, the character display form determination unit 63 obtains the change direction of the touch position based on the difference between the two touch positions detected in the latest frame and the previous frame.
The character display form determination unit 63 determines the rotation direction of the character C in the global coordinate system coordinate system based on the change direction of the touch position.

  For example, the character display form determination unit 63 determines the moving speed of the character C in the global coordinate system based on the change speed of the touch position detected at each predetermined time interval.

Specifically, in the present embodiment, when the swipe is in the second state (when the touch position is changed), the character display form determination unit 63 is detected in each of the latest frame and the previous frame. Based on the difference between the two touch positions, the change speed of the touch position is obtained.
The character display form determination unit 63 determines the moving speed of the character C in the global coordinate system based on the change speed of the touch position.

On the other hand, in the case of the third state of swipe (when the player's finger or the like is separated from the touch panel and the swipe is finished), the character display form determination unit 63 is immediately before the latest frame. The change speed of the touch position is obtained based on the difference between the two touch positions detected in the previous frame and the previous frame.
The character display form determination unit 63 determines the moving speed of the character C in the global coordinate system based on the change speed of the touch position.

Here, for convenience, the change amount, the change method, and the change speed of the touch position have been described as being individually calculated by the rotation controller display form determination unit 62 and the character display form determination unit 63.
However, in the present embodiment, as described above, the rotation controller RC and the character C are linked to the same touch operation (visible to the player so as to be linked).
Therefore, the change amount, the change method, and the change speed of the touch position are calculated by one of the rotation controller display form determination unit 62 and the character display form determination unit 63, and the calculation result is notified to the other. It may be.

  Further, the character display form determination unit 63 determines a change in the local coordinate system of the character C (for example, a motion change or rotation of the character C itself) as necessary.

The virtual space placement unit 64 places various objects in the virtual space of the global coordinate system so as to correspond to the determined display form.
As described above, the objects referred to here include not only the buttons B1 to B4, the rotation controller RC, and the character C, but also various objects constituting the background stored in the background storage unit 74. .

Here, in order to display an object placed in a three-dimensional virtual space on a two-dimensional display surface (touch panel), it is necessary to project the object in two dimensions. In other words, it is necessary to display on the touch panel how the virtual camera in the virtual space has photographed the object.
Therefore, the projection unit 65 projects each object in the virtual space two-dimensionally according to a predetermined projection method.

  The projection method is not particularly limited, but in the present embodiment, general perspective projection is adopted for objects such as the character C and the background. On the other hand, parallel projection is adopted for the objects of the rotation controller RC and the buttons B1 to B4.

The perspective projection is a projection method that uses a so-called perspective method, and is a projection method that produces a projection result similar to that seen with the naked eye. The perspective projection is also called “center projection” or “perspective”.
An object projected by perspective projection is displayed small on the touch panel when positioned far from the virtual camera position (viewpoint), and large when positioned near the virtual camera position (viewpoint). Displayed on the touch panel.

On the other hand, parallel projection refers to a projection method in which an object having the same size is projected with the same size regardless of the position in the three-dimensional virtual space.
Objects that employ parallel projection are always displayed on the touch panel with the same size, regardless of whether they are located far from or near the virtual camera position (viewpoint).

  Here, the projection method of the rotation controller RC and the character C can be the same.

However, when unified with perspective projection, the display size (display area) of the rotation controller RC on the touch panel changes. For this reason, it becomes unsuitable to use the rotation controller RC as a virtual controller (simulated trackball) of a 3D game.
That is, in order to use the rotation controller RC as a virtual controller (simulated trackball) for a 3D game, the display size of the rotation controller RC on the touch panel needs to be always constant without changing. Is done.
In order to meet the request when unified in perspective projection, the distance between the rotation controller RC and the viewpoint (camera position) is calculated to be always constant, and the coordinates of the rotation controller RC are based on the calculation result. Therefore, the processing load increases.

  On the other hand, when unified by parallel projection, such an increase in processing load is eliminated, but the perspective method cannot be applied to an object such as the character C that should exist in the virtual space on the game. That is, it becomes very difficult to realize the 3D game itself.

  From the above, in this embodiment, parallel projection is adopted as the projection method (camera) of the rotation controller RC. On the other hand, perspective projection is adopted as the projection method (camera) of the character C to be operated.

In the present embodiment, the position (viewpoint) of the virtual camera changes at least in the projection according to the projection method (camera) of the character C.
For example, in this embodiment, a position separated by a predetermined distance behind the character C is set as the viewpoint. In this case, the viewpoint moves in conjunction with the movement of the character C. Specifically, for example, when the player swipes in the right direction, the moving direction of the character C is also changed to the right direction, so that the viewpoint is similarly changed to the right direction.

The display control unit 54 performs control to display a two-dimensional image indicating the projection result of the projection unit 65 on the touch panel (more precisely, the display unit 27) in units of frames.
That is, an image in which the rotation of the rotation controller RC and the movement of the character C in the virtual space are interlocked according to the player's swipe, specifically, for example, the game execution screen 41 of FIG. 2 described above is displayed on the touch panel. .

Next, referring to FIG. 4, a series of processes for displaying an execution screen (for example, the game execution screen 41 of FIG. 2) during the execution of the 3D game among the processes executed by the player terminal 1 of FIG. 1 ( Hereinafter, the “game display process” will be described.
That is, FIG. 4 is a flowchart for explaining an example of the flow of the game display process.
The game display process is started when the game execution starts.

In step S1, the display control unit 54 of FIG. 3 displays a game space (virtual space) including the character C on the touch panel (more precisely, the display unit 27).
It is assumed that the rotation controller RC is not included in the virtual space at the stage of step S1.

In step S2, the operation detection unit 51 determines whether or not a touch operation has been received.
In a state where the user's finger or the like is not in contact with or close to the touch panel, it is determined as NO in Step S2, and the process proceeds to Step S12.
In step S12, the operation detection unit 51 and the like determine whether or not an instruction to end the process has been given. The instruction to end the process is not particularly limited. For example, it is assumed here that an instruction to end the game is adopted.
That is, when an instruction to end the game is given, it is determined as YES in Step S12, and the game display process is ended.
On the other hand, if the game end instruction has not been issued yet, it is determined NO in step S12, the process returns to step S2, and the subsequent processes are repeated.
That is, when the game end instruction has not yet been made and the user's finger or the like is not in contact with or in proximity to the touch panel, the loop process of step S2NO and step S12NO is repeated.

  When the user's finger or the like touches or approaches the touch panel during the loop process, a touch operation is accepted, and it is determined as YES in Step S2, and the process proceeds to Step S3.

In step S3, the operation detection unit 51 determines whether or not the touch position received in step S2 is a button position.
The button position refers to an area on the touch panel where buttons (buttons B1 to B4 in the example of FIG. 2) are arranged.
When a predetermined button (any of buttons B1 to B4 in the example of FIG. 2) is tapped, it is determined as YES in Step S3, and the process proceeds to Step S4.
In step S4, the CPU 21 (game execution unit or the like not shown) executes button execution processing. The button execution process refers to a process for exerting a function assigned to a tapped button.
When the button execution process is executed, the process proceeds to step S12.

  On the other hand, when the touch operation is performed at a position other than the button position, it is determined as YES in Step S3, and the process proceeds to Step S5.

In step S5, the display control unit 54 displays the rotation controller RC on the touch panel.
In the present embodiment, the display position of the rotation controller RC is the touch position received in the process of step S2.

In step S6, the operation detection unit 51 determines whether or not the touch position has changed.
For example, if the touch operation accepted in step S2 is a tap, it is determined as NO in step S6, and the process proceeds to step S12.

On the other hand, the case where the touch position is changed means a case where the second state of swipe is detected. In such a case, it is determined as YES in Step S6, and the process proceeds to Step S7.
In step S <b> 7, the display form determination unit 53 determines a display form in which the rotation controller RC and the character C are linked.
In step S8, the display control unit 54 causes the rotation controller RC and the character C to be displayed on the touch panel in the display form determined in step S7.
In the case of the rotation controller RC, the display form here means the rotation direction, the rotation amount, and the rotation speed in the local coordinate system, while in the case of the character C, the movement direction in the global coordinate system, It means the amount of movement and the movement speed.

  In step S9, the operation detection unit 51 determines whether or not the touch operation has been released.

When the touch operation is continued, that is, when the second state of the swipe is continued, it is determined as NO in Step S9, the process is returned to Step S6, and the subsequent processes are repeated.
That is, when the touch position continues to change (when the second swipe state continues), the loop processing of steps S6 to S9 is repeated, and the rotation of the rotation controller RC and the movement of the character C in the virtual space are repeated. 2 is displayed on the touch panel, for example, the game execution screen 41 of FIG. 2 described above.

On the other hand, when the touch operation is released, that is, when the third state of the swipe indicating the end of the swipe is detected, it is determined as YES in Step S9, and the process proceeds to Step S10.
In step S10, the display form determining unit 53 determines the display form of the rotation controller RC. In addition, the display form here means the rotation speed of the rotation controller RC.
In step S11, the display control unit 54 displays on the touch panel the stop of the movement of the character RC in the game space (virtual space) and displays the rotation controller RC in the display form determined in step S12. Let
Thereafter, the process proceeds to step S12.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within a scope that can achieve the object of the present invention are included in the present invention. is there.

For example, in the above-described embodiment, the objects that are linked by a predetermined instruction operation are the rotation controller RC and the character C, but are not particularly limited to this set.
Here, an object corresponding to the rotation controller RC is referred to as a “first object”, and an object corresponding to the character C is referred to as a “second object”.
In this case, it is sufficient that the first object and the second object have the following relationship, and any object can be adopted.
In other words, the first object need only be an object indicating a virtual three-dimensional rotating body in which one or more amounts relating to rotation in the local coordinate system change according to a predetermined instruction.
The second object may be an object whose amount changes by one or more in accordance with the predetermined instruction (the same instruction).
That is, the first object and the second object change in conjunction with the same instruction operation, and the former change amount is one or more arbitrary amounts relating to rotation in the local coordinate system, and the latter The amount of change is an arbitrary amount of 1 or more.
That is, it is not particularly necessary to set the second object as an operation target object, and it is not necessary to set the first object as a virtual controller.
However, when applied to a 3D game, it is preferable to use the second object as the content to be operated and the first object as a virtual controller because the operability of the player is increased.

Specifically, for example, an object indicating various kinds of rotating bodies as shown in FIG. 5 can be adopted as the first object.
The first object RC1 in FIG. 5A is a spherical object, like the rotation controller RC of the above-described embodiment.
The first object RC2 in FIG. 5B is a wine barrel-like object.
The first object RC3 in FIG. 5C is a columnar object.
The first object RC4 in FIG. 5D is a conical object.
Thus, the first object only needs to have a virtual three-dimensional shape imitating a rotating body that can rotate in real space, and it is particularly necessary that the first object has a symmetrical shape like a cone in FIG. Absent.
However, when the first object is used as a virtual controller like the rotation controller RC of the above-described embodiment, it is preferable that the first object has a spherical shape. This is because it is possible to easily handle multi-directional input expressions.
Also, as shown in FIG. 5, it is preferable to apply a texture to the first object so that the player can clearly convey the state of rotation of the first object to the player.

Here, the series of processes described above can be executed by hardware or can be executed by software.
In other words, the functional configuration of FIG. 3 is merely an example, and is not particularly limited. That is, it is sufficient that the information processing system has a function capable of executing the above-described series of processing as a whole, and what functional block is used to realize this function is not particularly limited to the example of FIG. Further, the location of the functional block is not particularly limited to that shown in FIG. 3, and may be arbitrary.
Specifically, for example, each functional block shown in FIG. 3 is provided in the player terminal 1 as a native application in the above-described embodiment, but can be implemented as a Web application using HTML and JavaScript (registered trademark). A server or the like (not shown) can also be provided.
In addition, one functional block may be constituted by hardware alone, software alone, or a combination thereof.

When a series of processing is executed by software, a program constituting the software is installed on a computer or the like from a network or a recording medium.
The computer may be a computer incorporated in dedicated hardware. The computer may be a computer capable of executing various functions by installing various programs, for example, a general-purpose smartphone or personal computer other than a server.

  The recording medium including such a program is not only constituted by a removable medium (not shown) distributed separately from the apparatus main body in order to provide the user with the program, but is also provided to the user in a state of being incorporated in advance in the apparatus main body. It is composed of a provided recording medium or the like.

In the present specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in time series along the order, but is not necessarily performed in time series, either in parallel or individually. The process to be executed is also included.
Further, in the present specification, the term “system” means an overall apparatus configured by a plurality of devices, a plurality of means, and the like.

In other words, the information processing program to which the present invention is applied can take various embodiments having the following configurations, including the information processing system as the embodiment of FIG. 3 described above.
That is, an information processing program to which the present invention is applied is
A computer that executes control for displaying an image on a display medium (for example, a touch panel including the touch operation input unit 76 and the display unit 27 in FIG. 3),
A first object (for example, a rotation controller RC in FIG. 2) indicating a virtual three-dimensionally shaped rotating body in which one or more amounts relating to rotation in the local coordinate system change according to a predetermined instruction, and according to the predetermined instruction A display control step (for example, FIG. 3) that displays on the display medium an image (for example, the game execution screen 41 in FIG. 2) including the second object (for example, the character C in FIG. 2) whose one or more types change. The display control unit 54 executes)
As the predetermined instruction operation, a detection step (for example, a step executed by the operation detection unit 51 in FIG. 3) for detecting an operation of contact or proximity of an object to the display medium;
A determination step of determining the one or more amounts relating to the rotation of the first object and determining the one or more amounts of the second object based on the detected operation (for example, the display of FIG. 3); Steps executed by the form determining unit 53),
An information processing program for executing control processing including:

Thus, the first object and the second object change in conjunction with the same instruction, and the former change amount is one or more arbitrary amounts related to rotation in the local coordinate system, The latter change amount is an arbitrary amount of 1 or more.
Therefore, by arranging the second object in the virtual space of the global coordinate system and using it as the operation target object, various various 3D games can be realized.
In this case, the first object can be used as a virtual controller for operating the second object.
As a result, the player can feel that the second object has moved in conjunction with the first object given the predetermined instruction.
In addition, since the second object has a virtual three-dimensional shape, it matches the three-dimensional virtual space.
In this way, a technology capable of realizing a virtual controller suitable for a 3D game is established.

  Note that the above information processing program is only capable of realizing a virtual controller suitable for a 3D game, and is not dedicated to a 3D game. That is, as described above, the information processing program can be applied to an arbitrary field in which the first object and the second object are interlocked with the same instruction.

Here, the detection step repeatedly detects the position of the object on the display medium while the object is in contact with or close to the display medium,
The determining step may include a step of determining a rotation amount of the first object in the local coordinate system based on a change amount of the position of the object detected at each predetermined time interval.
The determining step may include a step of determining a rotation direction of the first object in the local coordinate system based on a change direction of the position of the object detected at each of the predetermined time intervals. it can.
Therefore, when the swipe is adopted as the predetermined instruction, the rotation direction and the rotation amount of the first object change according to the swipe amount (the movement amount of the finger or the like on the touch panel) and the swipe direction (the movement direction of the finger or the like on the touch panel). .
As a result, the first object can be handled as a virtual trackball (controller).

In this case, the second object is an object that moves in a virtual three-dimensional space,
The determining step further determines a movement amount of the second object in the global coordinate system based on a change amount of the position of the object detected at each of the predetermined time intervals, and at each of the predetermined time intervals. The method may include determining a moving direction of the second object based on the detected change direction of the position of the object.
As a result, the movement amount and movement direction of the second object in the global coordinate system change in conjunction with the rotation amount and rotation direction of the first object viewed as a virtual trackball. That is, the second object can be used as an object to be operated by a virtual trackball (virtual controller).
As a result, the player can freely move the second object in the virtual space by swiping the first object with the same feeling as operating the actual trackball. In this case, the first object rotates as if it were a real trackball, and the second object also moves in the virtual space in conjunction with the rotation.
That is, the player can experience not only the operation feeling but also the visual experience similar to that when operating the actual trackball.

Further, the determination step is based on a change speed of the position of the object detected at a predetermined time before the detection of the release when the contact of the display medium of the object or the release of the proximity of the object is detected in the detection step. And determining a rotational speed of the first object in a local coordinate system.
The determination step may determine to reduce the rotation speed of the first object when the state of contact of the display medium with the object or release of proximity is maintained.
As a result, the third swipe state in which the player's finger or the like is separated from the touch panel (the end of the swipe) is handled equivalently to the state in which the player's hand is released from the actual trackball. As a result, it is possible to reproduce the state of the rotation of the actual trackball after the player's hand is released from the actual trackball as the rotation of the first object as a virtual trackball. .

Here, the display control step performs control to display an image including the first object represented by the first projection method and the second object represented by the second projection method on the display medium. can do.
Thereby, a 1st object can be appropriately displayed in the virtual space where a 2nd object exists.
In particular, when the first object is employed as a virtual controller (trackball), it is desirable that the size of the first object is always the same. In this case, the first projection method may be a parallel projection method, and the second projection method may be a perspective projection method.

As described above, the amount of change between the first object and the second object is determined based on the same predetermined instruction by executing the information processing program to which the present invention is applied. Here, the change amount of the first object is one or more arbitrary amounts related to rotation in the local coordinate system, and the latter change amount is an arbitrary amount of one or more.
Note that the present invention is not limited to the information processing program described above, and can be easily applied to a program that can execute the following processing.
For example, the amount of change of the first object (for example, the virtual movement of the controller) is determined based on a predetermined instruction (for example, a player's touch operation), and the amount of change of the second object (for example, the virtual object controller) The present invention can be easily applied to a program or the like that can execute a process for determining the movement of a character or the like.
For example, conversely, a change amount of the second object (for example, movement of a character or the like) is determined based on the change amount based on a predetermined instruction (for example, a player's touch operation), and the first based on the change amount. The present invention can be easily applied to a program or the like that can execute a process for determining an object change amount (for example, a virtual controller rotation movement).
