Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration example of a video game processing device 100 according to an embodiment of the present invention. As shown in FIG. 1, the video game processing device 100 includes a game program reading unit 10, a control unit 11, a storage unit 12, a display unit 13, an audio output unit 14, a player operation receiving unit 15, and a communication unit 16. Including.

The program reading unit 10 has a function of reading a necessary video game program from a storage medium including a storage medium in which various video game programs are stored. In this example, the program reading unit 10 has a mounting unit for mounting the removable game cartridge 20 in which the video game program is stored, and is determined by a player (operator (user) of the video game processing device 100). The game program is read from the storage medium of the game cartridge 20 mounted on the mounting unit and stored in the storage unit 12. In the video game executed according to the video game program used in this example, a state in which a character arranged in the virtual space moves according to an operation input by a player such as an RPG, a simulation game, or a battle game is displayed. It can be any video game. That is, it may be a video game in which the player can directly or indirectly control the position of the virtual camera.

The control unit 11 has a function of executing a game program read by the program reading unit 10 and stored in the storage unit 12 and executing various controls for advancing the video game according to the operation of the player.

The storage unit 12 is a storage medium for storing a video game program and various data necessary for advancing a video game. The storage unit 12 is composed of a non-volatile memory such as a RAM. The storage unit 12 stores various information registered / updated as the game progresses, and various information used in the game read from the storage medium built in the game cartridge 20.

The video game processing device 100 may be configured to download the video game program from a game program providing server (not shown) via a communication network such as the Internet and store it in the storage unit 12.

In this example, the storage unit 12 includes a virtual camera information storage unit 12a.

The virtual camera information storage unit 12a is a storage medium that stores virtual camera information that is information about the virtual camera. In this example, the control unit 11 specifies the position of the virtual camera in the three-dimensional virtual space based on the virtual camera information, and generates an image to be displayed on the display screen of the display device 13 according to the specified position.

FIG. 2 is an explanatory diagram showing an example of a storage state of virtual camera information stored in the virtual camera information storage unit 12a. As shown in FIG. 2, the virtual camera information includes the position and orientation of the virtual camera and the operation mode flag.

Here, the operation mode of the virtual camera in this example will be described. In this example, the operation modes of the virtual camera are classified into three modes (forward mode, rotation mode, and follow-up mode). The operation mode of the virtual camera is classified according to the difference in the method of moving the position and orientation of the virtual camera according to the operation input. That is, in a general 3D game, the subject (the center of the control target) is the player character, and the virtual camera follows the movement and turning of the player character, whereas in this example, the subject is, in principle, the virtual camera. Yes, the display mode of the player character is determined according to the movement or turning of the virtual camera.

The forward mode is a mode in which the virtual camera operates in a three-dimensional virtual space according to an operation rule (forward rule) for moving the virtual camera forward or backward in a predetermined direction. In this example, the control unit 11 is a virtual camera according to the distance and speed at which the player character advances when the player character advances in a moving field (a virtual space in which the player character can move in response to an operation by the player). To move forward. The position of the player character in the virtual space is used as the reference position for determining the position of the virtual camera in the forward mode. However, the configuration of the reference position is not limited to this, and for defining the position of the virtual camera in the virtual space, for example, the viewpoint position of the player character and the position where the player character and other objects can be overlooked in the virtual space. Any configuration may be used as a reference.

The rotation mode is a mode in which the virtual camera operates according to an operation rule (rotation rule) for rotating the virtual camera around a point in the three-dimensional virtual space. In this example, the control unit 11 rotates the virtual camera around a reference position set in the virtual space. The configuration of the reference position is not particularly limited, and may be a configuration that serves as a reference for defining the rotation direction, such as the same position as the reference position used in the forward mode or the position of the player character.

The follow-up mode is a mode in which the virtual camera operates according to an operation rule (follow-up rule) for following a specific object in a three-dimensional virtual space. In this example, when the player character in the moving field changes the direction of travel and moves forward, the control unit 11 follows the virtual camera according to the distance and speed at which the player character changes the direction of travel and moves forward ( Or follow). That is, the follow-up mode in this example is a mode in which the virtual camera operates in the other two modes (forward mode and rotation mode).

The virtual camera information storage unit 12a in this example includes an operation mode flag in order to control the movement of the virtual camera in a plurality of operation modes by one input interface provided with a touch panel. The operation mode flag in this example includes a flag corresponding to the forward mode, the rotation mode, and the follow mode. The control unit 11 sets a flag corresponding to the mode (so-called active mode) in which the player's operation is accepted according to the progress of the video game (for example, "1" is set in the corresponding cell), and the player Fold the flag corresponding to the mode in which the operation of is not accepted (for example, set "0" in the corresponding cell). Switching between each mode will be described in detail later.

The display unit 13 is a display device that displays a game screen according to the progress of a video game or a player operation under the control of the control unit 11. In this example, the control unit 11 executes a process (rendering) of generating a game screen including an image taken by a virtual camera. The display unit 13 is composed of, for example, a liquid crystal display device.

The audio output unit 14 outputs audio according to the progress of the video game and the player operation according to the control of the control unit 11.

The player operation receiving unit 15 receives an operation signal corresponding to the player operation and notifies the control unit 11 of the result. In this example, the operation receiving unit 15 receives the player's operation via the touch panel provided on the display unit 13.

The communication unit 16 connects to a communication network such as the Internet wirelessly or by wire, and transmits and receives various information.

Next, the operation of the video game processing device 100 of this example will be described.

FIG. 3 is a flowchart showing an example of display processing executed by the video game processing device 100. In the display process, a process for displaying a game screen showing the state (situation) of the player character in the virtual space is performed. The contents of the processing not related to the present invention may be omitted. Further, the "display processing" in this example does not limit the contents of the flowchart described below, but defines the processing name.

The display process is started, for example, when a screen (moving field display screen) showing the player characters arranged in the moving field is displayed according to the progress of the video game.

FIG. 4 is an explanatory diagram showing an example of a moving field display screen. As shown in FIG. 4, a three-dimensional virtual space including a player character PC is displayed on the moving field display screen.

In the display process, first, the control unit 11 receives a touch operation by the player (step S101). In this example, the control unit 11 sets a predetermined area on the moving field display screen (for example, the entire display screen including the player character) as a touch operation receiving area. That is, when the control unit 11 detects a touch operation (for example, a player's finger touching the touch panel) with respect to a predetermined area on the moving field display screen, it determines that the touch operation has been accepted. The configuration of the touch operation receiving area is not limited to this, and may be configured to detect contact by the player in a closed area (for example, a virtual controller) provided on the game screen, or an area indicating the player character PC. The configuration may be such that the contact by the player is detected in an area other than the above.

Here, if it is determined that the touch operation is not accepted (N in step S101), the control unit 11 shifts to the process of step S105 described later. On the other hand, if it is determined that the touch operation has been accepted (Y in step S101), the control unit 11 sets the position (initial position) where the touch operation has been accepted (step S102). In this example, the control unit 11 sets the coordinates indicating the position where the player's finger touches on the touch panel to the initial touch position (initial position). In this example, the control unit 11 sets the "initial position" to be used in the display process by registering the information indicating the coordinates in a predetermined storage area in the storage 12.

When the initial position is set, the control unit 11 determines whether or not the touch position has moved (step S103). Here, if it is determined that the touch position has not moved (Y in step S103), the control unit 11 determines whether or not a predetermined time (for example, 1 second) has elapsed since the initial position was set (for example, 1 second). Step S104). That is, the control unit 11 determines whether or not the player has continued to touch substantially one point (specifically, a range having an area having a play area) on the moving field display screen for a predetermined time.

Here, if it is determined that the predetermined time has not elapsed (N in step S104), the control unit 11 shifts to the process of step S103. On the other hand, when it is determined that the predetermined time has elapsed (Y in step S104), the control unit 11 sets the set initial position as the continuously touched position for the predetermined time, and performs another process (in this example, in this example). It is set to the starting point touch position (starting point position) as the starting point in the movement-related processing described later (step S105).

When the starting point position is set, the control unit 11 executes a process (movement-related process) related to moving the player character PC (step S200). In the movement-related processing in this example, the position and orientation of the virtual camera are moved according to the operation of the player, and the processing for moving the player character is executed. The movement-related processing will be described in detail later (see FIG. 6).

When the movement-related processing is executed, the control unit 11 determines whether or not to end the display processing (see FIG. 3) (step S106). In this example, the control unit 11 determines whether or not to end the display process based on the end conditions of the display process corresponding to the progress of the video game (for example, clearing a so-called quest or time-up). Here, if it is determined that the display process is not completed (N in step S106), the control unit 11 shifts to the process in step S101. On the other hand, when it is determined that the display process is finished (Y in step S106), the control unit 11 ends the process here.

Further, in the process of step S103 in the display process, when it is determined that the touch position has moved (Y in step S103), the control unit 11 determines whether or not the slide operation by the player has been accepted (step S107). In this example, the control unit 11 determines whether or not the slide operation has been accepted based on the distance between the set initial position and the current touch position.

Here, for example, when the distance between the initial position and the position where the player's finger is currently in contact with the display screen (current touch position, that is, the touch position after or during movement) is less than a predetermined distance, the slide operation is performed. When it is determined that the above is not accepted (N in step S107), the control unit 11 updates the initial position to the current touch position (current position) (step S111), and proceeds to the process of step S104 described above. In this case, the control unit 11 determines whether or not the touch operation for the initial position has been detected for a predetermined time based on the time of the touch operation for the initial position after the update. That is, in this example, the control unit 11 erroneously operates a touch position movement operation of less than a predetermined distance (for example, an operation by the player of moving a fingertip touching the touch panel up, down, left, or right while touching the touch panel). Not treated as a slide operation. That is, the range defined by this "predetermined distance" from one point indicating this initial position is the so-called play area. The criteria (erroneous operation determination criteria) that the control unit 11 considers to be an erroneous operation are not particularly limited, and are preferably considered according to the content of the video game and the size of the game screen.

On the other hand, if it is determined that the slide operation has been accepted because, for example, the distance between the initial position and the current touch position is equal to or greater than a predetermined distance (Y in step S107), the control unit 11 determines that the virtual camera is in accordance with the current touch position. The position of is changed (step S108). In this example, the control unit 11 sets the operation mode of the virtual camera to the rotation mode, and rotates the position of the virtual camera according to the direction in which the current touch position is located with respect to the initial position.

FIG. 5 is an explanatory diagram showing an example of a moving field display screen after accepting a slide operation. It is assumed that the touch operation by the player is accepted from the state of the moving field display screen shown in FIG. 4, and the accepted touch operation moves to the upper part of the screen before the elapse of a predetermined time. In this case, the control unit 11 changes the position of the virtual camera to a lower position than the previous position in order to display the virtual space located above the currently displayed virtual space, and directs the virtual camera. Is changed upward from the previous orientation. In this example, the control unit 11 indicates the position of the virtual camera in the direction indicated by the slide operation (after the slide operation from the initial position) with the coordinates (rotation center) in the virtual space provided with reference to the position of the player character as the center. Rotate by the amount corresponding to the length of the slide operation (the length from the initial position to the touch position after the slide operation) (opposite the direction toward the touch position). At this time, the control unit 11 sets the direction of the virtual camera to face the center of rotation. That is, in this example, the control unit 11 moves the virtual camera on the surface of the sphere centered on the reference position in the virtual space at an arbitrary speed.

The rotation method of the virtual camera is not limited to this, and for example, the length (range) of the operation of the control unit 11 and the slide is stored in a plurality of stages (for example, 4 stages), and the slide by the player. Depending on the acceptance of the operation, the stage to which the slide operation belongs may be specified, and the virtual camera may be rotated by the amount of rotation corresponding to the specified stage. With such a configuration, for example, when the slide operation is short, the amount of movement of the virtual camera is smaller than when the slide operation is long, so that the operability can be improved. That is, the control unit 11 moves the virtual camera more finely (slowly) when it accepts a short slide operation, and moves the virtual camera larger (faster) when it accepts a long slide operation. Therefore, it becomes possible to realize the control of the virtual camera according to the intention of the player.

Further, regarding the correspondence between the direction of the slide operation and the rotation direction of the virtual camera, the control unit 11 may be configured so that the correspondence can be changed according to the operation by the player. That is, for example, with a so-called in-game optional function, the operation direction may be reversed, or the movement direction of one virtual camera may be associated with one operation direction. With such a configuration, the virtual camera does not necessarily rotate in the opposite direction so as to reflect the slide operation direction, and operability according to the player's preference can be realized.

When the position of the virtual camera is changed, the control unit 11 determines whether or not the slide operation is completed (step S109). Here, for example, when it is determined that the slide operation is not completed due to the continuous change of the touch position (N in step S109), the control unit 11 shifts to the process of step S108. On the other hand, if it is determined that the slide operation is completed (Y in step S109) because, for example, the touch position has not changed for a specific time or more, the control unit 11 determines whether or not the touch operation is completed (step). S110). Here, for example, when the player's finger is not touching the touch panel, the control unit 11 determines that the touch operation is completed (Y in step S110), and proceeds to the process of step S106 described above.

On the other hand, for example, when it is detected that the player's finger is in contact with the touch panel even after the slide operation, the control unit 11 determines that the touch operation has not been completed (N in step S110), and updates the initial position. (Step S111). With such a configuration, when the player does not move the finger from the current position after the slide operation, the control unit 11 starts the movement-related processing.

FIG. 6 is a flowchart showing an example of movement-related processing executed by the video game processing device 100. In the movement-related processing, processing for moving the position and orientation of the virtual camera is performed according to the operation of the player. The contents of the processing not related to the present invention may be omitted.

In the movement-related processing, first, the control unit 11 starts moving the virtual camera (step S201). In this example, the control unit 11 sets the movement mode of the virtual camera to the forward mode, and the direction according to the direction of the virtual camera of the player character (for example, the same as the direction of the virtual camera when the virtual space is viewed in a plane). Start moving in the direction). At this time, the moving speed of the virtual camera and the moving speed of the player character are made substantially the same.

When the movement of the virtual camera is started, the control unit 11 receives the area (or slide operation) for receiving the slide operation by the player with reference to the starting point position set in the process of step S105 in the display process (see FIG. 3). An area for notifying the player to that effect) (slide operation reception area) is set (step S202). In this example, the control unit 11 displays an image showing the slide operation setting area on the display screen according to the setting of the slide operation reception area in the game screen.

FIG. 7 is an explanatory diagram showing an example of a slide operation receiving area. As shown in FIG. 7, the control unit 11 includes an image showing the starting point position SP at a portion where the player's finger P is in contact with the touch panel, and a slide operation receiving area SA having a predetermined shape centered on the starting point position image. Is displayed.

When the slide operation reception area SA is displayed, the control unit 11 determines whether or not the slide operation has been accepted (step S203). In this example, the control unit 11 receives the slide operation in the displayed slide operation reception area SA. However, the shape of the slide operation receiving area is not particularly limited, and may be, for example, a rectangle or a circle. Further, the control unit 11 may be configured not to display the slide operation receiving area. Further, the control unit 11 may be configured to display an image only for notifying the player that the slide operation is being accepted.

Here, the slide operation is not accepted because the current touch position (current position) matches the starting point position SP (or because it is located within a specific distance from the starting point position SP). If it is determined (N in step S203), the control unit 11 shifts to the process of step S206 described later. On the other hand, when it is determined that the slide operation has been accepted by detecting that the current position is different from the starting position SP (Y in step S203), the control unit 11 determines the position of the virtual camera according to the current position. Change (step S204). In this example, the control unit 11 sets the operation mode of the virtual camera to the follow-up mode, and rotates the position of the virtual camera according to the positional relationship between the starting point position SP and the current position. Further, in this example, the control unit 11 changes the traveling direction of the player character in the direction in which the current position is located with respect to the starting point position SP. When giving priority to the operation mode of the virtual camera as the main body, the control unit 11 defines the movement path of the virtual camera according to the operation input of the player, and moves the virtual camera according to the defined movement path ( Alternatively, a time lag may be provided so that the movement of the player character follows the movement of I and the virtual camera.

FIG. 8 is an explanatory diagram showing an example of a moving field display screen after accepting a slide operation. It is assumed that the player accepts a slide operation (for example, a slide operation to the left of the screen with respect to the starting point position SP. See FIG. 8) from the state of the moving field display screen shown in FIG. In this case, the control unit 11 changes the traveling direction of the player character to the left and rotates the position of the virtual camera to the right. As a result, for example, as shown in FIGS. 7 and 8, the control unit 11 moves the position of the virtual camera so as to follow the player character. Further, in this example, when the touch position after the slide operation is on the left side of the screen with respect to the initial position, the control unit 11 sets the rotation direction of the virtual camera to the right and initializes the rotation speed of the virtual camera. Set according to the length from the position to the touch position after the move operation. That is, in this example, the virtual camera continues to rotate unless the player matches the touch position with the starting position SP. In this example, the control unit 11 changes the traveling direction of the player character in the same direction as the direction of the slide operation. The correspondence between the direction of the slide operation and the direction of changing the traveling direction of the player character or the direction of moving the virtual camera is not particularly limited, and it is preferable that the player is configured so as not to give a sense of discomfort.

When the position of the virtual camera is changed, the control unit 11 determines whether or not the slide operation is completed (step S205). Here, for example, if it is determined that the slide operation is not completed because the current position is not in the vicinity of the starting point position SP or the starting point position SP and is in the slide operation receiving area SA (N in step S205), The control unit 11 shifts to the process of step S204.

On the other hand, if it is determined that the slide operation is completed (Y in step S205) because the current position is near the starting point position SP, for example, the control unit 11 determines whether or not the touch operation is completed (step S206). ). Here, for example, when it is determined that the touch operation is not completed by the player's finger touching the touch panel (N in step S206), the control unit 11 shifts to the process of step S203. When the touch position is moved to the outside of the slide operation reception area SA by the slide operation, the control unit 11 assumes that the frame portion (edge) of the slide operation reception area SA that last detected the touch position is touched. Assuming that, control the position of the virtual camera. However, when the touch position moves out of the slide operation reception area SA, the control unit 11 performs a process of changing the operation mode of the virtual camera, for example, a process of providing a new slide operation reception area, and a slide amount of the rotation speed of the virtual camera. It may be configured to execute a process of increasing by a standard different from the above, or a process of rotating the virtual camera without changing the traveling direction of the player character.

On the other hand, when it is determined that the touch operation is completed by detecting that the player's finger is separated from the touch panel (Y in step S206), the control unit 11 ends the movement of the virtual camera (step S207). The process proceeds to the process of step S106 of the display process (see FIG. 3). At this time, the control unit 11 stops the movement of the player character and sets all the flags corresponding to the three operation modes of the virtual camera to "0". That is, the operation mode is set to the stop mode. The method of determining the end of the touch operation is not limited to this. For example, when the condition for ending the display of the moving field (moving field end condition) is satisfied, the control unit 11 ends the touch operation. It may be configured to determine that it has been done. In this case, the control unit 11 may be configured to start the process for displaying the game screen according to the satisfied movement field end condition.

As described above, in the above-described embodiment, the virtual space captured by the virtual camera is displayed on the display screen of the display device (for example, the display unit 13) provided with the touch panel (for example, the moving field display). The video game processing device 100 that controls the progress of the video game (by displaying the screen) has a predetermined closed area (for example, an area less than a predetermined distance from the initial position. The shape of the area is not particularly limited) on the display screen. According to the detection of the touch operation by the player for a predetermined time (for example, continuously for 1 second or longer) on the entire game screen), the virtual camera follows a predetermined first rule (for example, a forward rule). The position is controlled (for example, step S201), and the position of the virtual camera is controlled according to a predetermined second rule (for example, rotation rule or follow-up rule) in response to detecting a touch position change operation by the player on the display screen. (For example, steps S108 and S204), the operability of the virtual camera can be improved.

That is, one input interface (particularly, a display screen provided with a touch panel) has a plurality of rules without providing a plurality of input interfaces corresponding to the movement of the virtual camera according to a plurality of rules (for example, a plurality of operation modes). Since the virtual camera can be moved in the virtual space while switching between, the operability of the virtual camera can be improved when the user (for example, the player) can operate the virtual camera directly or indirectly. become able to. In particular, since the player can switch the operation mode of the virtual camera with one hand, the portability can be improved when the video game processing device is a mobile terminal.

Further, in the above-described embodiment, the video game processing device 100 is configured to control the position of the player character in the virtual space according to the content of the touch operation by the player (for example, step S201), so that the player is virtual. It will be possible to provide a video game with good operability in which the player character can be moved just by being aware of the operation of the camera.

Further, in the above-described embodiment, the video game processing device 100 moves the player character PC forward or backward based on the position of the virtual camera controlled according to the first rule (for example, the forward rule) (for example, step S201). Since it is configured, it becomes possible to provide a video game that can be operated intuitively to the player.

Further, in the above-described embodiment, the video game processing device 100 moves the position of the virtual camera closer to or further away from the reference position (for example, the position of the player character) in the virtual space (for example, the direction in which the player character advances). ) To move the position of the virtual camera (for example, skip S201), and rotate the position of the virtual camera around the reference position or the rotation reference position (for example, the position of the player character) in the virtual space different from the reference position (for example). , Skip S107, S204), it is possible to provide the player with a video game in which the virtual camera can be operated by using a plurality of operation modes having different operation feelings.

Further, in the above-described embodiment, the video game processing device 100 sets an operation area (for example, a slide operation reception area SA) on the display screen according to the start of control of the position of the virtual camera (for example, the slide operation reception area SA). In step S202), the position of the virtual camera is controlled based on the calculation standard corresponding to the set operation area and the touch position after the change operation (for example, step S204), so that the range for accepting the slide operation can be easily set. You will be able to adjust.

Further, in the above-described embodiment, the video game processing device 100 starts controlling the position of the virtual camera in response to detecting the touch operation for a predetermined time (for example, step S201), and controls the position of the virtual camera. After starting, the movement of the virtual camera ends when the end of the touch operation (for example, the player releases the finger from the touch panel or the touch position moves out of the slide operation reception area SA) is detected ( For example, since the configuration is set to step S207), it is possible to provide a video game in which the start and end of virtual camera control can be easily operated.

Further, in the above-described embodiment, when the video game processing device 100 detects a touch position change operation by the player while the movement of the virtual camera is controlled (for example, Y in step S203), the player character Since the movement direction is changed according to the content of the change operation (for example, step S204), when the movement direction of the player character is changed, the position of the virtual camera is controlled to follow the player character. It becomes possible to display a similar display screen.

Further, in the above-described embodiment, the video game processing device 100 sets the position where the touch operation is received as the initial position (for example, step S102), and determines whether or not the touch operation with respect to the initial position is detected for a predetermined time. (For example, step S104), according to the movement of the touch position from the initial position, it is determined whether or not the movement is a slide operation according to a predetermined erroneous operation determination criterion (for example, step S107), and it is not a slide operation. When it is determined that the initial position is updated to the touch position after movement (for example, step S111), and when the initial position is updated, the touch operation for the initial position is performed based on the time of the touch operation for the updated initial position. Since it is configured to determine whether or not it has been detected for a predetermined time, it is possible to effectively determine and process whether or not the input is unintended by the player.

The configuration for setting the initial position is not limited to the above-described embodiment (see step S102 in FIG. 3). For example, the video game processing device 100 starts timing in response to receiving a touch operation. However, when the time that the touch position is located within a specific range (for example, within the range of a specific shape centered on the position where the touch position is first detected) continues for a specific time (for example, 1 second), it is specified. The initial position when the time has elapsed may be set as the starting point position, and the movement-related processing (for example, step S200; see FIG. 6) may be started. With such a configuration, it is possible to change the operation mode of the virtual camera based on the position where the player touches the touch panel and touches the touch panel when a certain time elapses without significantly shifting the position. Further, in this case, as compared with the above-described embodiment, the frequency of updating the initial position can be suppressed, and the load of the video game processing device required for the display processing can be reduced.

Although not particularly mentioned in the above-described embodiment, when the video game processing device 100 detects a plurality of touch positions in an identifiable manner and the number of touch positions is a predetermined number (for example, one place), the touch is performed. Regardless of whether or not the operation is detected for a predetermined time, the position of the virtual camera is controlled according to the predetermined first rule, and when the number of touch positions is a specific number (for example, two places), whether or not the change operation is detected. Regardless of this, the position of the virtual camera may be controlled according to a predetermined second rule (for example, in the case of two locations, it may be rotated to the left, and in the case of three locations, it may be rotated to the right). With such a configuration, it is possible to provide a video game in which the operation mode of the virtual camera can be switched by the number of fingers that the player touches the touch panel.

Although not particularly mentioned in the above-described embodiment, the video game processing device 100 may be configured to accept operation inputs for a plurality of operation modes. That is, for example, when the control unit 11 controls the virtual camera to move forward or follow in response to a touch operation at one place and accepts a slide operation for another position on the touch panel, the slide operation is performed. May be regarded as an operation input for the rotation mode, and the position of the virtual camera may be rotated around the position of the player character. With such a configuration, for example, the player moves only the position of the virtual camera with the index finger while inputting operations for the forward mode and the follow mode with the middle finger (that is, moving the player character and the virtual camera). It will be possible to provide a video game that can be made to.

In the above-described embodiment, the case where the video game processing device 100 includes a touch panel has been described as an example, but the configuration of the embodiment of the present invention is not limited to this, and for example, the video game processing device is a touch panel. The configuration may include other operation receiving means (for example, an operation button, an operation switch, an operation key, an acceleration sensor, or a controller configured by combining these). That is, the video game processing device 200 having at least a controller other than the touch panel (not shown) displays the virtual space captured by the virtual camera on the display screen of the display device according to the operation content of the controller to display the video game. The position of the virtual camera is controlled according to a predetermined first rule according to the detection of a pressing operation on an operating member (for example, a mechanical button) provided in the controller for a predetermined time when controlling the progress of the pressing operation. The position of the virtual camera may be controlled according to a predetermined second rule according to the detection of the end of the pressing operation before the elapse of a predetermined time after the detection.

The video game processing device 200 including at least a controller other than the touch panel may be configured to control the position of the player character in the virtual space according to the operation content of the controller. Further, the video game processing device 200 may be configured to move the player character forward or backward based on the position of the virtual camera controlled according to the first rule (for example, the forward rule). Further, the video game processing device 200 moves the position of the virtual camera in the direction of moving the position of the virtual camera closer to or farther from the starting point position in the virtual space, and sets the reference position or the rotation reference position in the virtual space different from the reference position. The position of the virtual camera may be rotated as the center. Further, the video game processing device 200 starts controlling the position of the virtual camera in response to detecting the pressing operation for a predetermined time, starts controlling the position of the virtual camera, and then detects the end of the pressing operation. Therefore, the control of the position of the virtual camera may be terminated.

Further, although not particularly mentioned in the above-described embodiment, the video game processing device 100 displays the virtual space captured by the virtual camera on the display screen of the display device provided with the touch panel to advance the progress of the video game. When controlling, the detected touch position is set as the starting point position according to the detection of the touch operation on the display screen, and a specific time interval (or a specific number of frames) is set according to the setting of the starting point position. The current touch position is specified as the current position by (interval), and the starting point position is updated in the direction toward the current position according to the fact that the current position has not changed for a certain period of time, and the positional relationship between the starting point position and the current position is changed. A configuration that identifies the process to be executed according to the process (for example, the process of moving the virtual camera from the starting point position to the current position at a speed according to the distance between the starting point position and the current position) and executes the specified process. May be. That is, for example, when the video game processing device 100 detects a touch operation on the display screen, the detected touch position is set as the starting point position, and the current starting point position is set at a specific time interval. The touch position of is specified as the current position, the starting point position is updated in the direction toward the current position according to the fact that the current position has not changed for a certain period of time, and the touch position is based on the positional relationship between the starting point position and the current position. The content of the change operation may be specified, and the position of the virtual camera may be controlled based on the content of the specified change operation.

FIG. 9 is an explanatory diagram showing an example when the video game processing device 100 updates the starting point position. When the moving field display screen is displayed in the state shown in FIG. 8 (assuming that the starting point position has not been updated), it is assumed that the player's finger P has stopped at the position shown in FIG. 8 for a certain period of time. In that case, the control unit 11 updates the starting point position SP in the direction toward the current touch position (current position) (specifically, updates the position information). That is, when the state in which the player's finger P is stopped at the position shown in FIG. 8 continues, the control unit 11 sets the starting point position SP corresponding to the initial position FP to the position corresponding to the current position CP, as shown in FIG. Move at a predetermined speed toward. Further, the control unit 11 updates the slide operation receiving area SA from the position corresponding to the initial position FP to the position corresponding to the current position CP by updating the starting point position SP.

When the video game processing device 100 is configured to update the starting point position, the control unit 11 directs the updating speed of the starting point position (or the starting point position toward the current position) based on the distance between the starting point position and the current position. It may be configured to determine the moving speed). That is, for example, the video game processing device 100 may be configured to control the speed at which the starting point position is moved according to the moving speed of the virtual camera on the spherical surface. Specifically, if the rotation angle is smaller than the predetermined threshold value, the moving speed of the starting point position may be slowed down, and if the rotation angle is larger than the predetermined threshold value, the moving speed of the starting point position may be increased.

Further, when the video game processing device 100 is configured to update the starting point position, the locus for updating the starting point position SP toward the current position by the control unit 11 is when the update is started from the position where the update is started. It may be configured to be a straight line toward the current position. In this case, for example, in the case shown in FIG. 9, the video game processing device 100 passes the slide operation receiving area SA from the position SA (= FP) corresponding to the initial position, passes through the position 901, and corresponds to the current position. Move to position SA (CP). The configuration relating to the update of the starting point position is not limited to the configuration in which the starting point position moves linearly at a predetermined speed. For example, the video game processing device 100 may instantly move the starting point position SP to the current position CP. Alternatively, the starting point position SP may be moved so as to move along the locus of the touch position by the player.

Further, although not particularly mentioned in the above-described embodiment, the position of the virtual camera is moved by a predetermined movement method according to the predetermined operation in response to the reception of the predetermined operation by the video game processing device 100. It may be configured to be used. That is, for example, when the video game processing device 100 receives a double tap on the area where the player character PC is displayed, the virtual camera is instantly switched to the position determined by Yaw 180 degrees in the current orientation (or the virtual space). (Rotate 180 degrees at high speed around the position of the player character in). Further, at this time, the video game processing device 100 may be configured to orient the player character instantly or at a predetermined speed toward the camera.

In the above-described embodiment, the video game processing device 100 is configured to execute various processes such as the above-mentioned game processing based on the game program read from the game cartridge 20, but the video game processing device 100 is configured. A part or all of the game program may be acquired via a communication network such as the Internet. Further, the video game processing device 100 may function as a game server and provide a part or all of the game program to the game terminal via the communication network.
