Description

The present invention relates to a computer game device, a control method and program for controlling the computer game device, and a recording medium storing the program, and more particularly to a technique for controlling a user interface in a game device having a touch screen function. .

Computer game devices and intelligent devices (hereinafter simply referred to as “game devices”) having a touch screen (touch panel) function are known. Such a game device has a user (game image) displayed on a touch screen.
The player can perform an operation directly and interactively by performing a touch operation, thereby providing the user with an intuitive user interface environment different from an input device such as a conventional operation button.

For example, when a user touches a specific object in a game image that represents a virtual three-dimensional space displayed on the touch screen with a finger, the game device can determine from the display position of the object and the touched position, It can be determined that the object has been selected. Further, when the user moves the touched finger with respect to the object at a predetermined speed (usually slowly) without releasing it from the touch screen, the game apparatus determines that the drag operation is performed. The display of the object can be controlled so as to move along the line. Furthermore, the game device responds to an action of flipping with a finger on the touch screen or an action of quickly wiping with a finger (that is, an action of moving the touched finger without releasing it at a predetermined speed or higher). Thus, the display of the game screen itself or a predetermined object can be controlled. Such an operation of flipping with a finger or an operation of wiping with a finger is generally called a flick operation or a swipe operation.

In Patent Document 1 below, the user selects all the characters in the range surrounded by an operation surrounding the range on the game screen on the touch panel, and further indicates a position on the game screen. A technique for setting the position as the movement destination of all the selected characters is disclosed.

Further, in Patent Document 2 below, when an input is given by a touch operation to a player character displayed on a touch-panel-type second display screen that is linked to the first display screen, the first display screen is displayed according to the input. A technique for changing the game image displayed on the screen is disclosed.

A circuit that implements a communication standard such as G is mounted. In the present disclosure, the communication form is premised on wireless communication, but does not exclude wired communication such as wired LAN.

The operation button 260 is typically composed of a plurality of buttons (keys), but is not limited thereto. In this example, left and right operation button sets including a cross button and a round button are provided.

Next, the game provided to the user by the game device 100 of the present embodiment will be briefly described. Such a game is performed by the game device 100 using the computing device 21.
This is realized by executing the game program under the control of zero.

In this example, it is assumed that the game provided by the game device 100 is a tennis game. Typically, in a tennis game, a user (player) operates a player character, hits a ball object with an opponent player character operated by a computer (that is, the game device 100), and plays virtual reality tennis. It is to play in a game format. In this example, it is assumed that the player is a singles who plays a one-on-one match. In order to enhance the virtual reality of the user, the game screen displayed on the display 221 is typically a game image representing a virtual three-dimensional space. During play, the viewing direction and field of view of the virtual camera are controlled, and the game image representing the virtual three-dimensional space changes accordingly. Similar to a normal tennis game, the player character needs to enter an appropriate hit point position in order to hit the ball object. For this reason, the user is required to perform an operation for moving the player character more accurately.

The user operates the player character by a touch operation on the touch screen 220 (touch operation with a finger or a stylus, etc., hereinafter the same), releases a serve shot, moves the player character to a desired position, and moves the ball. You can strike back an object. In this example, a touch operation for a shot is required following a touch operation for movement. The shot direction, strength, type, etc. are the timing and position of the touch operation,
Based on factors such as direction, speed, etc., computing device 2
10 is computed and determined. The operation action by the user's touch operation includes, for example, a tap operation, a drag operation, and a flick operation. The computing device 210 determines an operation action from a given touch operation as necessary.

The tap is an operation in which the user's finger simply touches the touch screen 220 (touch down). Typically, after the touch down, lift-up is performed (finger is released). The computing device 210 can determine a single tap operation or a double tap operation based on the number of tap operations performed within a predetermined time.

The drag operation is an operation of dragging a finger on the touch screen 220. Specifically,
This is an operation of forming a stroke by moving the touched-down finger on the touch screen 220 at a predetermined speed or less without releasing it. That is, whether the operation is a tap operation or a drag operation can be distinguished depending on whether the touched-down finger moves two-dimensionally.

The flick operation is an operation of flipping with a finger or an operation of quickly wiping with a finger, and specifically, an operation of lifting a touch-down finger while moving at a predetermined speed or more. Whether the operation is a drag operation or a flick operation can be distinguished depending on whether the finger is moved at a predetermined speed or higher and lifted up within a predetermined time.

For example, during play, the user taps a predetermined point on the play area including the court in order to move the player character on the court in the virtual three-dimensional space. Thereby, the movement target position of the player character is set, and the player character moves to the movement target position. At this time, the line-of-sight direction and / or visual field area of the virtual camera is also controlled in accordance with the movement of the player character. As a result, a game image including a player character moving on the court is displayed on the touch screen 220. This also eliminates the need for the user to continue the touch operation when moving the player character.

The user can change the movement target position by tapping another new point while the player character is moving. Subsequently, the user performs a flick operation in a direction in which the player wants to hit the ball object in order to cause the player character that has moved to the desired movement target position to make a shot. Thereby, the player character can strike back the flying ball object. The accuracy of the shot depends on, for example, the timing of starting the flick operation, the direction, the speed, the stroke distance, and the like. Further, the user can select a shot type (for example, top spin, slice, volley, lob, smash, etc.) according to the situation based on the form of the flick operation. As a result, the user can quickly perform the touch operation for moving the player character, and can estimate the start timing of the flick operation for the shot while the player character is moving to the desired movement target position. An operation time for a flick operation according to the type can be provided.

Further, the user may move the player character by a drag operation. In the case of a drag operation, the user can move the player character by following the movement of the moving finger. For a player character that has moved to the desired movement target position,
As described above, the user can give a shot action.

Further, the user can move the player character by a flick operation. In the case of a flick operation, the user can set an arbitrary point as the movement target position and move the player character according to the form of the flick operation. As will be apparent from the present disclosure, when the user moves the player character by a flick operation, it is not necessary to directly specify the movement target point in the virtual three-dimensional space. In other words, even if there is a movement target position outside the game image in a game image of a certain play scene, the user can set the movement target position using a flick operation. Accordingly, the game image representing the virtual three-dimensional space changes in accordance with the movement of the player character that moves to the movement target position. This also eliminates the need for the user to continue the touch operation when moving the player character.

FIG. 4 is a block diagram for explaining a functional configuration of the game apparatus 100 according to the embodiment of the present invention. That is, the figure shows various functions realized in the game apparatus 100 in cooperation with other hardware / software by the processor (that is, the processor core 211) of the computing device 210 executing the game program. This figure shows the configuration of the functional means, and in the figure, functional means related to the game realized by the game program of the present embodiment are particularly illustrated.

With reference to the figure, a game control unit 401 is a functional means for comprehensively controlling the progress of a game realized by a game program. For example, in the case of a tennis game, the game control unit 401 performs computer processing so that a virtual reality tennis game between the player character and the opponent player character is developed. Data necessary for the progress of the game is stored in the game data storage unit 402. The game control unit 401 controls the player character behavior control unit 4 that controls movement of the player character and other actions (for example, shots).
011 is included.

The touch operation unit 403 receives a touch operation by the user and outputs an operation signal corresponding to the touch operation to the touch operation processing unit 406. The display unit 404 displays a game image based on a signal output from the image generation unit 408 under the control of the game control unit 401. The touch operation unit 403 and the display unit 404 can be associated with the touch screen 220 described above. Also, the audio output unit 405 generates sound based on the signal output from the audio generation unit 409 under the control of the game control unit 401. The audio output unit 405 can be associated with the audio output unit 230 shown in FIG.

The touch operation processing unit 406 determines the type (operation action) of the touch operation given to the game apparatus 100 based on an operation signal corresponding to the touch operation on the touch operation unit 403. The touch operation processing unit 406 of this example includes a position information acquisition unit 4061 and an operation action determination unit 4062.

The position information acquisition unit 4061 acquires position information on the display unit 404 (display 221) related to the touched position based on the operation signal sent from the touch operation unit 403. The position information acquisition unit 4061 uses the acquired position information as the operation action determination unit 4062.
Output to.

The operation action determination unit 4062 determines the type of touch operation (operation action) by the user based on the position information sent from the position information acquisition unit 4061 and the time information obtained from the timer 407. The operation action is, for example, as described above, a tap operation,
There are drag operations and flick operations.

The image generation unit 408 is a functional unit that generates a game image based on the image data output from the game control unit 401 and outputs the game image to the display unit 404.

The audio generation unit 409 generates a game sound based on the audio data output from the game control unit 401 and outputs the game sound to the audio output unit 405.

FIG. 5 is a flowchart for explaining the player character behavior control process in the game apparatus 100 according to the embodiment of the present invention. In the following, a behavior control process in a rally between a player character and an opponent player character will be described.

As shown in the figure, the touch operation processing unit 406 of the game apparatus 100 is in progress of the game.
Whether or not there is a touch operation by the user on the touch operation unit 403 is monitored at predetermined time intervals (STEP 501). When the touch operation processing unit 406 determines that there is a touch operation (YES in STEP 501), the touch operation processing unit 406 determines a type of the touch operation, that is, an operation action based on the touch operation (STEP 502). The touch operation is detected by time sampling, and an operation signal corresponding to the touch operation is output. The operation action determination process will be described with reference to FIG.

Subsequently, the game control unit 401 determines whether or not the player character can perform a swing motion to shot the ball object according to the determined operation action and the status of the game in progress (STEP 503). When the game control unit 401 determines that the swing operation is not possible for the touch operation (No in STEP 503), the game control unit 401 performs a player character movement process (STEP 504).
). The player character movement process will be described with reference to FIG. On the other hand, the game control unit 401 determines that a swing motion is possible for the touch operation (
(Yes in STEP503), swing processing for controlling the swing motion of the player character is performed (STEP505). The player character swing process will be described with reference to FIG.

In this example, the game control unit 401 is configured to determine that the touch operation by the user during the rally is either the player character movement process or the swing process, but the present invention is not limited thereto. Alternatively, any one of a plurality of operation processing groups including other operation processing may be selected.

FIG. 6 is a flowchart for explaining the operation action determination process in the game apparatus 100 according to the embodiment of the present invention.

In other words, as shown in the figure, the game control unit 401 of the game apparatus 100 is configured with the touch operation unit 4.
When an operation signal is received from 03, position information on the touch screen 220 is acquired based on the operation signal (STEP 601). Subsequently, the game control unit 401 determines whether or not the touch operation is moving (STEP 602). The game control unit 401 can determine that the touch operation is moving when there is a difference in a series of position information acquired at predetermined time intervals.

The game control unit 401 determines that the touch operation has not moved (STEP 6).
(No in 02), the current (latest) position information is output (STEP 603), and then it is determined whether or not the finger has been released within a predetermined time (STEP 604). If the game control unit 401 determines that the finger has not been removed within a predetermined time (NO in STEP 604), STEP 60
Return to 1. On the other hand, when the game control unit 401 determines that the finger has been released within a predetermined time (YES in STEP 604), the operation action determination process ends.

On the other hand, when the game control unit 401 determines that the touch operation is moving (STE
In Step P602, the game control unit 401 calculates the moving speed of the touch operation (S
TEP605). The game control unit 401 can calculate the moving speed from a series of position information acquired at predetermined time intervals. Subsequently, the game control unit 401 determines whether or not the calculated moving speed is greater than a predetermined speed v (STEP 606). Game control unit 401
If it is determined that the calculated moving speed is equal to or lower than the predetermined speed v (No in STEP 606)
), The current position information is output (STEP 603). That is, in this example, the game control unit 40
No. 1 processes the drag operation by the touch operation as a continuous tap operation or the tap operation as a drag operation with a short stroke distance. In contrast, the game control unit 401
Is determined that the calculated moving speed is greater than the predetermined speed v (Y in STEP 606)
es), the operation action is determined as a flick operation (STEP 607), the movement direction and the movement speed (movement vector) are output (STEP 608), and the process is terminated.

FIG. 7 is a flowchart for explaining the player character movement process in the game apparatus 100 according to the embodiment of the present invention.
That is, as shown in the figure, the game control unit 401 determines whether or not the operation action is a flick operation (STEP 701). When the game control unit 401 determines that the operation action is not a flick operation (No in STEP 701), the game control unit 401 regards it as a tap operation or a drag operation, sets the output position information as target position information (STEP 702), and The display of the game image is controlled so that the player character moves toward the movement target position (STEP 703).

On the other hand, when the game control unit 401 determines that the operation action is a flick operation (YES in STEP 701), the game control unit 401 calculates a movement target position based on the output movement direction and movement speed (STEP 704). The game control unit 401 controls display of the game image so that the player character moves toward the movement target position (STEP 703).
). In other words, in the present disclosure, the operation parameters such as the moving direction and the moving speed by the flick operation are used for calculating the movement target position of the player character, and are directly given to the position data of the player character by directly giving the player character. It is not used to calculate the behavior of In the present disclosure, the behavior calculation of the player character is performed based on the calculated movement target position.

10 to 14 are diagrams showing game screens for explaining the movement of the player character by the flick operation. In this example, it is assumed that the player character P is required to take a hit point position behind the court in a certain play scene. At this time, a part of the area behind the court is located outside the game screen (FIG. 10).

In order to perform a flick operation, the user touches any position on the touch screen with a finger and performs a touch operation that quickly moves to the near side. At the moment when the user touches, the game control unit 401 detects this, and first displays a motion cursor (displayed as a double circle) C at the touched position (FIG. 10).

When the user quickly moves his / her finger away from the touch screen, the game control unit 40
1 determines that the operation action is a flick operation. The game control unit 401 moves and displays the motion cursor C to a position where the finger is released. The game control unit 401 determines that the shot is not possible based on the position information of the ball object, and enters a process for moving the player character P to the movement target position calculated based on the flick operation. In this example, for example, a target mark M is displayed so that the movement of the player character P to the movement target position is intuitively transmitted to the user. The target mark M is, for example, a display with a virtual glow, but is not limited thereto. That is, the game control unit 401 highlights the current position of the player character with a glow (FIG. 11).

Subsequently, the game control unit 401 starts the movement of the target mark M so that the glow moves to the movement target position calculated by the flick operation (FIG. 12). In line with this,
The game control unit 401 is configured so that the player character P follows the target mark M.
The movement is started (FIG. 13). Depending on the configuration of the game screen according to the angle of the virtual camera, the target mark M may temporarily disappear outside the game screen. The game control unit 401 changes the configuration of the game screen as necessary as the player character P moves, and finally the target mark M where the player character P is at the movement target position.
The display is controlled so as to catch up with (FIG. 14). Thus, the user can shot the ball object by the next touch operation.

FIG. 8 is a flowchart for explaining the swing process of the player character in the game apparatus 100 according to one embodiment of the present invention. The swing process is the same as the STE in FIG.
This is executed when it is determined in P503 that the touch operation can swing. In this example, it is assumed that the swing process is executed based on a flick operation.

That is, as shown in FIG. 8, the game control unit 401 sets the shot target position according to the moving direction and moving speed obtained by the flick operation (STEP 801). The shot target position is a target position where the player character tries to strike back the ball object by a shot. Next, the game control unit 401 selects a preset swing action from
Swing motion candidates that can be applied in the situation of the game in progress are extracted (STEP 802).
). The swing motion includes, for example, a forehand and a backhand, and top spin, slice, volley, rob, smash, and the like that are fed out from these. Game control unit 40
1 extracts candidate swing motions that can be applied in consideration of position information and speed information related to the ball object, position information of the player character, time to shot (number of frames), and the like. Typically, the earlier the player character can reach the hit position, the more swing motion candidates that can be extracted. Subsequently, the game device 100 determines an optimum swing motion from the extracted swing motion candidates based on the timing of the flick operation, the moving direction, and the moving speed (STEP 803). Then, the game control unit 401
Controls the display of the game image so that the player character swings according to the determined swing motion, and in combination with this, while calculating the trajectory of the ball object,
The display of the hit ball object is controlled (STEP 804).

Although not described in this example, the game apparatus 100 may accept, for example, an operation from the operation button by the user during the swing of the player character, move the shot cursor, and adjust the shot target position. good.

As described above, according to the present disclosure, the user can give an arbitrary touch operation to the player character regardless of the configuration of the game screen displayed on the touch screen. In particular, even if the movement target position of the player character is outside the game screen in a certain scene, the movement target position can be set by an intuitive touch operation.

Further, according to the present disclosure, it is possible to cause the player character to perform a series of actions by a combination of intuitive touch operations, and to improve the interest of the game.

The present invention can be widely applied to a computer game device having a touch screen function and a game program executed by an intelligent device typified by a smartphone or a tablet computer.
