(Detection of input operation)
FIG. 4 is a diagram illustrating processing in which the input operation receiving unit 191 detects the type of input operation. In the example of FIG. 4, the position on the touch screen 130 detected by the touch panel 131 is set in each of 11 arrays from the array fp [0] to the array fp [10] of the storage unit 150 that stores the user information 153. The history information shown is stored. The history information is stored in the history information table every predetermined period (for example, every frame rate). The number of arrays in which history information is stored is not limited and may be any number. In the history information table, history information detected when touch-on is performed from touch-off may be stored in the storage unit 150 as initial position coordinates.

  As illustrated in FIG. 4, for example, when history information (x0, y0) is stored in the array fp [0] to the array fp [9] and a null value is stored in the array fp [10], The input operation reception unit 191 determines that the input operation is a tap operation. For example, when the null value is stored after the history information is changed in the touch now state, the input operation reception unit 191 has the array fp [3] and the array fp immediately before the array fp [5] in which the null value is stored. Refer to the history information stored in [4]. The input operation reception unit 191 determines that the input operation is a flick operation when the distance between the positions indicated by the history information of the arrays fp [3] and fp [4] is greater than or equal to a preset threshold value. Determine. Further, after the history information changes in the touch now state, for example, when the history information (x15, y15) is stored in the arrays fp [4] to fp [10], the input operation reception unit 191 performs the input operation by a drag operation. Determine that there is.

(Detection of moving direction)
FIG. 5 is a diagram illustrating a process in which the moving direction detection unit 193 detects a direction in which the game character is moved in accordance with a user input operation. The movement direction detection unit 193 sets a position (initial touch position) where the user presses the touch screen 130 by bringing a finger or the like closer to the touch panel 131 from the state where the user is not pressing the touch screen 130 as a starting point. When the input operation reception unit 191 determines that the user's operation is a drag operation, the input operation receiving unit 191 determines the game character based on the coordinates that are the starting point and the coordinates that the touch screen 130 detects the approach of the user's finger or the like. The direction to move is detected.

  A state (A) in FIG. 5 shows a state in which the user brings his / her finger closer to the touch screen 130 from a state in which the user's finger has left the touch screen 130. The input operation reception unit 191 detects that the user's finger has approached the touch panel 131 and stores the detected coordinates as user information 153 in the storage unit 150 as an initial touch position.

  In the example of FIG. 5, the coordinates of the initial touch position held by the storage unit 150 are indicated as initial touch position coordinates 155. The input operation reception unit 191 does not detect the detection result of the touch screen 130 (the coordinates at which the user's finger is approaching the touch screen 130 and the fact that the user's finger is approaching the touch screen 130 ( The detection result “null”)) is stored in the buffer memory as user information 153 for a certain number of frames. The buffer memory can store the detection results on the touch screen 130 for each frame (in the example of FIG. 5, 11 frames from the array fp [0] to the array fp [10] in the example of FIG. 5). The buffer memory can be realized as a ring buffer, for example.

  In the example of the state (A), the position where the user pressed the touch screen 130 is shown as a pressed position 30A (coordinates (x0, y0) of the touch screen 130).

  In the state (B) of FIG. 5, the user performs a drag operation on the touch screen 130, and the pressing position on the touch screen 130 is changed from the pressing position 30A to the pressing position 30B (coordinates (x9, y9) of the touch screen 130). It is shown that the frame is moved by 10 frames (10 frames from array fp [0] to array fp [9]). The input operation reception unit 191 stores the detection result of the touch screen 130 in the buffer memory as user information 153, and refers to the value held in the buffer memory to determine that the user's operation on the touch screen 130 is a drag operation.

  In the state (C) of FIG. 5, the position where the user is pressing the touch screen 130 is set to 5 frames (array fp [10], from the pressed position 30B to the pressed position 30C (coordinates (x14, y14) of the touch screen 130), This indicates that the movement is performed by 5 frames (fp [0], fp [1], fp [2], and fp [3]).

  The state (D) of FIG. 5 shows the detection result of the input operation in which the movement direction detection unit 193 designates the direction in which the user moves the game character in each of the state (B) and the state (C). The movement direction detection unit 193 manages information (buffer memory writing position) indicating which memory area is the target of writing the coordinates of the pressed position detected by the touch screen 130 in the buffer memory.

  In the state (B), the movement direction detection unit 193 determines from the coordinate 31A (coordinate (x0, y0)) indicating the initial touch position to the coordinate 31B (coordinate (x9, y9)) based on the determination result of the input operation reception unit 191. ) Until the user performs a drag operation. The moving direction detection unit 193 moves the game character in a vector 32B ((y9-y0) / (x9-x0)) defined by the coordinates 31A and the coordinates 31B, starting from the coordinates 31A of the initial touch position. Detect as.

  In the state (C), the movement direction detection unit 193 drags the user from the coordinate 31B (coordinate (x9, y9)) to the coordinate 31C (coordinate (x14, y14)) based on the determination result of the input operation reception unit 191. Detects that an operation has been performed. The movement direction detection unit 193 moves the game character along a vector 32C ((y14−y0) / (x14−x0)) defined by the coordinates 31A and the coordinates 31C, starting from the coordinates 31A of the initial touch position. Detect as.

  As described above, the moving direction detection unit 193 detects the approach from the first touch position where it is detected that the user's finger is not approaching from the state where the user's finger is approaching, while the second approach is detected. When the detection position moves to the touch position, while detecting the approach, the operation direction, which is the direction from the first touch position to the second touch position, is assumed to be the virtual character of the game character CA1. It is determined as the moving direction in space.

(Control of virtual camera)
FIG. 6 is a diagram illustrating a process in which the camera arrangement control unit 194 controls the virtual camera VC. In FIG. 6, the camera work in which the virtual camera VC tracks the game character CA1 from behind will be described. In the state (A) of FIG. 6, the game character CA1 is shown moving in the direction D1 (movement direction). For example, when the input operation accepting unit 191 determines that the input operation by the user is a drag operation and the movement direction detection unit 193 detects the movement direction of the game character CA1 as the direction D1, the object control unit 195 displays the front of the game character CA1. Is directed in the direction D1, and the game character CA1 is moved in the direction D1. The camera arrangement control unit 194 controls the arrangement position and shooting direction of the virtual camera VC so as to track from behind the game character CA1. When tracking from behind the game character CA1, the camera arrangement control unit 194 makes an angle θ1 (corresponding relationship) between the shooting direction DV and the direction of the game character CA1 (direction D1) 0 °. The camera arrangement control unit 194 arranges the virtual camera VC so that the game character CA1 is displayed near the center of the camera view.

  The state (B) in FIG. 6 shows a state where the moving direction is changed from the direction D1 to the direction D2 by a drag operation by the user. In this case, the object control unit 195 moves the game character CA1 in the direction D2 while facing the front of the game character CA1 in the direction D2. At this time, the camera arrangement control unit 194 arranges the virtual camera VC and the shooting direction DV so that an angle θ1 (corresponding relationship) between the shooting direction DV and the direction (direction D1) of the game character CA1 is 0 °. To change. Note that the camera arrangement control unit 194 may detect the change angle θ2 in the movement direction before and after the change, and may use the detected change angle θ2 as the change angle θ3 of the virtual camera VC.

  As described above, the camera arrangement control unit 194 provides camera work for tracking the game character CA1 whose movement direction changes according to the input operation by the user from behind.

(Example of screen when moving)
FIG. 7 is a diagram for explaining camera work and operation objects that change in response to an input operation by a user. Screen examples (A) to (D) are images displayed on the touch screen 130. In the screen examples (A) to (D), the display control unit 196 causes the touch screen 130 to display an image taken from behind the game character CA1 by the camera arrangement control unit 194. When an input operation by the user is received by the input operation receiving unit 191, the object control unit 195 generates an operation object according to the user's input operation. The display control unit 196 causes the operation object to be superimposed on the image captured by the virtual camera VC and displayed on the touch screen 130.

  The screen example (A) is an example of a screen when the user performs an operation with a finger or the like approaching the touch screen 130. When it is determined by the input operation receiving unit 191 that the user has performed an operation with a finger or the like approaching the first position 300A of the touch screen 130, the object control unit 195 moves the circular operation object 300 in response to the input operation. Generate. The display control unit 196 displays the generated circular operation object 300 at the first position 300A that is the touch position. In the screen example (A), the shooting direction is indicated by the direction VD1, and the direction of the game character CA1 is indicated by the direction CD1. The correspondence (angle formed) between the direction VD1 as the shooting direction and the direction CD1 as the direction of the game character CA1 is 0 °.

  Screen example (B) is an example of a screen when the user performs a drag operation starting from first position 300A of screen example (A). The input operation accepting unit 191 accepts a drag operation from the first position 300A as a starting point to the second position 300B as an end point. When the drag operation is received by the input operation receiving unit 191, the object control unit 195 generates an operation object 300 indicating the operation result of the drag operation. The operation object 300 indicating the operation result of the drag operation expresses the operation result (for example, the operation direction) by associating the position that is the starting point of the drag operation and the position that is the end point. In the example of the screen example (B), the object control unit 195 extends from the first position 300A to the second position 300B so that the end of the operation object 300 is located at the position corresponding to the start point and the end point. The extended operation object 300 is generated. The display control unit 196 displays the extended operation object 300 on the touch screen 130. The operation direction and shooting direction in this state are shown. The operation direction is a direction SD1 (upper right direction in the figure), and the shooting direction is a direction VD1 (upward direction in the figure). The angle formed by the direction SD1 and the direction VD1 is θ4.

  Furthermore, when the drag operation is accepted, the movement direction detection unit 193 determines the movement direction of the game character CA1 as the same direction as the direction SD1 that is the operation direction. The object control unit 195 directs the game character CA1 in the moving direction and starts moving.

  When the orientation of the game character CA1 is changed in the screen example (B), the camera placement control unit 194 controls the placement position and shooting direction of the virtual camera VC so as to track the back of the game character CA1. Specifically, the shooting direction rotates clockwise around the point of sight (game character CA1) by θ4, which is an angle formed by the direction SD1 and the direction VD1. Further, the arrangement position of the virtual camera VC is controlled so that the game character CA1 or the moving destination is at the center of the screen. Thereby, the image displayed on the touch screen 130 changes from the screen example (B) to the screen example (C).

  Screen example (C) is an example of a screen when the shooting direction of the virtual camera in screen example (B) is changed. As shown in the screen example (C), when the shooting direction of the virtual camera VC is changed from the direction VD1 to the direction VD2, the direction SD1 that is the operation direction by the user in the screen example (B), that is, the operation object 300 The extending direction (extension direction) is changed in the virtual space of the game. In the screen example (C), the operation direction is a direction SD2 that is rotated to the right by θ4, which is an angle formed by the direction SD1 and the direction VD1. For this reason, the movement direction detection unit 193 changes the position of the starting point of the operation direction so that the correspondence between the operation direction and the movement direction is maintained before and after the change of the shooting direction of the virtual camera VC. Furthermore, the object control unit 195 changes the position of the starting point of the operation object 300 so that the correspondence between the operation direction and the movement direction is maintained before and after the change of the shooting direction of the virtual camera VC.

  The screen example (D) is an example of a screen when the position of the starting point in the operation direction and the position of the starting point of the operation object 300 are changed. The movement direction detection unit 193 changes the position of the starting point in the operation direction using any of the three methods.

  The first method is a method using a relative amount. The movement direction detection unit 193 uses the angle formed by the shooting direction (direction VD1) and the direction of the game character CA1 before the change of the shooting direction (screen example (A)) as a relative amount. When tracking from behind the game character CA1, the camera arrangement control unit 194 sets an angle θ1 (relative amount) between the shooting direction DV and the direction of the game character CA1 to 0 °. For this reason, the moving direction detection unit 193 changes the position of the starting point of the operation direction so that the angle formed by the operation direction and the shooting direction (direction VD2) is 0 °. Thereby, the position of the starting point in the operation direction is changed from the first position 300A to the second position 300C. Similarly, the object control unit 195 changes the position of the end of the operation object 300 so that the angle formed by the extension direction of the operation object 300 and the shooting direction (direction VD2) is 0 °. As a result, the position of the end of the operation object 300 is changed from the first position 300A to the second position 300C. According to the first method, the movement direction and the operation direction of the game character CA1 coincide with each other in the screen example (D).

  The second method is a method using a change amount. The movement direction detection unit 193 forms an angle between the shooting direction (direction VD1) before the change of the shooting direction (screen example (A)) and the shooting direction (direction VD2) after the change of the shooting direction (screen example (C)). Based on θ4 (for example, the amount of change in which the rightward rotation is positive), the position of the starting point in the operation direction is changed. The movement direction detector 193 changes the position of the starting point of the operation direction so as to rotate the direction SD2 as the operation direction in the reverse direction (left direction) by the angle θ4. Thereby, the position of the starting point in the operation direction is changed from the first position 300A to the second position 300C. Similarly, the object control unit 195 changes the position of the end of the operation object 300 so that the extending direction of the operation object 300 is rotated in the reverse direction (left direction) by the angle θ4. As a result, the position of the end of the operation object 300 is changed from the first position 300A to the second position 300C. By the second method, the moving direction and the operation direction of the game character CA1 coincide with each other in the screen example (D).

  The third method is a modification of the first method and uses a predetermined fixed value. In the first method, the movement direction detection unit 193 has the same angle θ1 (relative amount) between the shooting direction DV and the direction of the game character CA1 as the angle between the operation direction and the shooting direction (direction VD2). So that it is controlled. Here, when the angle θ1, which is a relative amount, is 0 °, that is, when the virtual camera VC is controlled to shoot the game character CA1 from behind the game character CA1, the shooting direction DV and the game character CA1. The direction of is always the same as the direction from bottom to top on the touch screen 130. Therefore, the movement direction detection unit 193 changes the position of the starting point of the operation direction so that the operation direction matches the direction from the bottom to the top on the touch screen 130. Thereby, the position of the starting point in the operation direction is changed from the first position 300A to the second position 300C. Similarly, the object control unit 195 changes the position of the end of the operation object 300 so that the operation object 300 matches the direction from the bottom to the top on the touch screen 130. As a result, the position of the end of the operation object 300 is changed from the first position 300A to the second position 300C. According to the third method, the movement direction and the operation direction of the game character CA1 coincide with each other in the screen example (D).

(Flow chart for moving operation)
FIG. 8 is a flowchart for explaining processing during a moving operation. The flowchart in FIG. 8 is a flowchart illustrating a process in which the control unit 190 advances the action game by executing the game program 151.

  In step S10, the control unit 190 determines whether an input operation has been accepted.

  If it is determined that the input operation has been accepted (step S10: Yes), in step S12, the control unit 190 displays an operation object at the initial touch position (corresponding to the screen example (A) in FIG. 7). The object control unit 195 generates a circular operation object 300 in response to the input operation. The display control unit 196 displays the generated circular operation object 300 at the first position 300A that is the touch position. The initial touch position is an initial value of a starting point (end position of the operation object) for determining the operation direction.

  In step S14, the control unit 190 determines whether or not the input operation is a drag operation. The control unit 190 determines whether the operation is a drag operation using the history information of the touch screen 130 (see FIG. 4).

  If it is determined that the input operation is a drag operation (step S14: Yes), in step S16, the control unit 190 displays the operation object 300 extending from the starting point (first position 300A) in the drag direction (direction SD1). (Corresponding to the screen example (B) in FIG. 7). The control unit 190 generates the operation object 300 using the history information of the touch screen 130 and displays the operation object 300 on the touch screen 130.

  In step S18, the control unit 190 detects the drag direction (direction SD1) of the drag operation using the history information of the touch screen 130 (see FIG. 5). Then, the control unit 190 determines the moving direction of the game character CA1 and the direction of the game character CA1 based on the drag direction (direction SD1). Then, the control unit 190 moves the game character CA1 in the drag direction (direction SD1) according to the movement direction (corresponding to the screen example (B) in FIG. 7).

  In step S20, the control unit 190 matches the shooting direction of the virtual camera VC with the direction of the game character CA1 (corresponding to the screen examples (C) in FIGS. 6 and 7).

  In step S22, the control unit 190 changes the position of the starting point in the operation direction and the end position of the operation object 300 (corresponding to the screen example (D) in FIG. 7). The control unit 190 changes the position of the starting point of the operation direction and the position of the starting point of the operation object 300 from the first position 300A to the second position 300C using a relative amount, a change amount, or a predetermined direction.

  In step S24, the control unit 190 determines whether or not the drag operation is completed. If it is determined that the drag operation has not been completed (step S24: No), the control unit 190 re-executes the processing from step S16 to step S24 described above. Thereby, while the touch screen 130 detects that the user's finger is approaching, that is, while the drag operation is continued, the operation object is displayed, and the position of the operation direction starting point and the operation object 300 are displayed. The position of the starting point is changed as appropriate.

  If it is determined that the drag operation is completed (step S24: Yes), the control unit 190 ends the movement of the game character CA1 as step S26. In step S28, the control unit 190 ends the display of the operation object 300.

  On the other hand, if it is determined that the input operation is not a drag operation (step S14: No), in step S24, the control unit 190 causes the game character CA1 to perform an action corresponding to the input operation. For example, in the case of a tap operation, an attack target is determined and the game character CA1 is caused to perform an attack action. In step S28, the control unit 190 ends the display of the operation object 300.

  When it is determined that the input operation is not accepted (step S10: No), or when the display of the operation object 300 is finished, the flowchart shown in FIG. 8 is finished. Then, the control unit 190 executes the flowchart shown in FIG. 8 from the beginning until a predetermined condition is satisfied. Thus, a series of processes at the time of the moving operation is completed.

(Other screen examples during move operation)
In the above description, the timing for changing the position of the starting point of the operation direction by the movement direction detection unit 193 and the timing for changing the position of the end of the operation object 300 by the object control unit 195 are virtual according to the orientation of the game character CA1. This is when the shooting direction of the camera VC changes. However, the shooting direction of the virtual camera VC is not limited to the example that is changed according to the direction of the game character CA1.

  FIG. 9 is a screen example when the shooting direction of the virtual camera VC is changed by a game event. Screen examples (A) to (D) in FIG. 9 are images displayed on the touch screen 130. In screen examples (A) and (B), the display control unit 196 causes the camera arrangement control unit 194 to display an image taken from behind the moving game character CA1 on the touch screen 130. That is, the direction SD1 that is the operation direction and the direction VD1 that is the shooting direction are the same.

  Screen example (B) is an example of a screen when volcano M1 at the upper right of the screen exploded as a game event. The camera arrangement control unit 194 performs a camera work for attracting the user's attention to the exploding volcano M <b> 1 and devise to increase the user's interest in the game. For example, the shooting direction is changed so that the target volcano M1 and the game character CA1 enter the field of view. As a result, the image displayed on the touch screen 130 changes from the screen example (B) to the screen example (C).

  The screen example (C) is an example of a screen when the shooting direction of the virtual camera VC is rotated 90 degrees to the right. In the screen example (C), the shooting direction of the virtual camera VC is changed from the direction VD1 to the direction VD2 so as to capture the game character CA1 from the side. Similarly to the example of FIG. 7, the direction SD1 that is the operation direction by the user in the screen example (B), that is, the extending direction (extending direction) of the operation object 300 is changed in the virtual space of the game. . Therefore, as in the example of FIG. 7, the movement direction detection unit 193 determines the position of the starting point of the operation direction so that the correspondence between the operation direction and the movement direction is maintained before and after the change of the shooting direction of the virtual camera VC. change. Furthermore, the object control unit 195 changes the position of the starting point of the operation object 300 so that the correspondence between the operation direction and the movement direction is maintained before and after the change of the shooting direction of the virtual camera VC. Thereby, in the example screen (D), the movement direction of the game character CA1 and the operation direction match.

(Summary of processing to change the starting position)
When the shooting direction of the virtual camera VC is changed, the control unit 190 matches the operation direction operated on the touch screen 130 with the moving direction of the character. For this reason, even when the shooting direction of the virtual camera VC is changed, the user can move the character in the dragged direction before changing the shooting direction without correcting the operation direction. Furthermore, the control unit 190 can freely change the camera work by linking the camera work and the operation direction, so that various user experiences can be provided.

(Overview of camera work during engagement)
In a general action game, not only a scene in which the game character CA1 moves in a virtual space field, but also a scene in which an enemy character (an example of a target character) placed in the virtual space is engaged.

  The user inputs not only a moving operation for moving the character in the virtual space but also an attacking action for causing the game character CA1 to perform an attacking action according to the scene. As described above, the moving operation is an input operation for instructing the moving direction of the game character, and is a directional operation. An example of the moving operation is a drag operation or a flick operation under a predetermined condition. On the other hand, the attack operation is an input operation for causing the game character CA1 to perform an attack action. An example of a basic attack operation is a tap operation. The attack operation includes a flick operation combined with a tap operation. Details will be described later.

  The camera arrangement control unit 194 provides camera work for tracking the game character CA1 whose movement direction changes according to an input operation by the user from behind. That is, the trigger (trigger) for the camera arrangement control unit 194 to change the shooting direction of the virtual camera VC is a moving operation by the user. Here, the camera arrangement control unit 194 further includes an attack operation as a trigger (trigger) for changing the shooting direction of the virtual camera VC. Thereby, at the time of a battle with an enemy character, the camera work for producing a sense of presence, power, a sense of unity with a character, etc. can be provided instantaneously.

(Screen example during engagement)
FIG. 10 is an example of a screen for explaining the shooting direction of the virtual camera VC during the battle. Screen examples (A) to (D) in FIG. 10 are images displayed on the touch screen 130. In the screen examples (A) to (D), the display control unit 196 causes the camera arrangement control unit 194 to display an image of the game character CA1 displayed on the touch screen 130. When an input operation by the user is received by the input operation receiving unit 191, the object control unit 195 generates an operation object according to the user's input operation. The display control unit 196 causes the operation object to be superimposed on the image captured by the virtual camera VC and displayed on the touch screen 130.

  The screen example (A) is an example of a screen when the enemy character CA2 enters the field of view during the movement operation. In the screen example (A), the shooting direction is indicated by the direction VD1, and the direction of the game character CA1 is indicated by the direction D3.

  Screen example (B) is an example of a screen when a tap operation that is an attack operation is performed in the situation of screen example (A). The object control unit 195 generates a circular operation object 300 in response to the tap operation. The display control unit 196 displays the generated circular operation object 300 at the touch position. At this time, if the distance between the enemy character CA2 and the game character CA1 is within a predetermined distance, the enemy character CA2 is determined as an attack target (lock-on). The game character CA1 is directed in the direction D4 of the enemy character CA2 that is locked on. The camera arrangement control unit 194 controls the virtual camera VC so that the virtual camera VC captures the game character CA1 from behind. The shooting direction of the virtual camera VC is changed to the direction VD2 that is the same direction as the direction D4 that is the direction of the game character CA1. As a result, the image displayed on the touch screen 130 changes from the screen example (B) to the screen example (C).

  The screen example (C) is an example of the screen when the shooting direction of the virtual camera VC is changed according to the attack operation. The screen example (D) is an example of a screen when an attack operation is performed on an enemy character. In this way, even when a non-directional operation such as a tap operation is performed, the shooting direction of the virtual camera VC is changed, and a realistic battle screen is provided.

(Flow chart for attack operation)
FIG. 11 is a flowchart for explaining processing during an attack operation. The flowchart of FIG. 11 is a flowchart illustrating a process of causing the control unit 190 to advance the action game by executing the game program 151.

  In step S30, the control unit 190 determines whether an input operation has been accepted. The control unit 190 can accept a moving operation for moving the game character CA1 in the virtual space and an attacking operation for causing the game character CA1 to perform an attacking action as input operations.

  If it is determined that the input operation has been received (step S30: Yes), in step S32, the control unit 190 displays an operation object at the initial touch position (corresponding to the screen example (B) in FIG. 10). The object control unit 195 generates a circular operation object 300 in response to the input operation. The display control unit 196 displays the generated circular operation object 300 at the touch position.

  In step S34, the control unit 190 determines whether or not the input operation is a tap operation. The control unit 190 uses the history information on the touch screen 130 to determine whether the operation is a tap operation (see FIG. 4).

  If it is determined that the input operation is a tap operation (step S34: Yes), in step S36, the control unit 190 determines whether an enemy character exists within the attack range. The attack range is set in advance with the game character CA1 as a reference.

  If it is determined that there is an enemy character within the attack range (step S36: Yes), in step S38, the control unit 190 specifies an enemy character that is an attack target. When there are a plurality of enemy characters within the attack range, the control unit 190 sets, for example, the enemy character closest to the game character CA1 as an attack target.

  As step S40, the control unit 190 directs the game character CA1 to the enemy character CA2 based on the position of the enemy character CA2 that is the target of the attack action and the position of the game character CA1 (FIG. 10). Corresponding to screen example (B)).

  As step S42, the control unit 190 determines the shooting direction of the virtual camera VC based on the direction of the game character CA1. The control unit 190 performs control so that the character is photographed from a predetermined direction with respect to the direction of the game character CA1. The predetermined direction with respect to the direction of the game character CA1 is, for example, a direction of shooting from behind the game character CA1, a direction of shooting from the side of the game character CA1, a direction of shooting from above the game character CA1, and the like. . As a specific example, the control unit 190 controls the virtual camera VC so that the shooting direction of the virtual camera VC coincides with the direction of the game character CA1 and shooting is performed from behind the game character CA1 (screen example in FIG. 10). Corresponding to (C)).

  In step S44, the control unit 190 causes the game character CA1 to perform an attack action (corresponding to the screen example (D) in FIG. 10). In step S46, the control unit 190 ends the display of the operation object 300.

  On the other hand, if it is determined that the input operation is not a tap operation (step S34: No), in step S48, the control unit 190 causes the game character CA1 to perform an action corresponding to the input operation. At this time, if the input operation is a moving operation such as a drag operation, the control unit 190 moves the game character CA1 as described in FIG. 8 and virtually tracks the game character CA1 moving in the virtual space. Control the camera VC. In step S46, the control unit 190 ends the display of the operation object 300.

  If it is determined that there is no enemy character within the attack range (step S36: No), the control unit 190 ends the display of the operation object 300 as step S46.

  When it is determined that the input operation is not accepted (step S30: No), or when the display of the operation object 300 is finished, the flowchart shown in FIG. 11 is finished. Then, the control unit 190 executes the flowchart shown in FIG. 11 from the beginning until a predetermined condition is satisfied. Thus, a series of processing at the time of the attack operation is completed.

(Sequential attacks during engagement)
In an action game, a continuous attack (so-called combo attack) may occur when attack operations are continuously received within a predetermined period. The content of such a combo attack is defined as combo data in the game information 152. In order to give diversity to the combo attack, a directional input operation may be employed for the attack operation during the combo attack. For example, a combo attack based on a series of input operations such as a tap operation, a tap operation, and a flick operation.

  FIG. 12 is a diagram illustrating an example of an action when the object control unit 195 causes the game character CA1 to perform an attack action based on the combo data. The state (A) in FIG. 12 shows action a1. The state (B) of FIG. 12 shows action a2. The state (C) of FIG. 12 shows action a3. When the input operation accepting unit 191 accepts the tap operation, the object control unit 195 causes the game character CA1 to execute the action a1, as shown in the state (A) of FIG. Subsequently, when the input operation receiving unit 191 receives the tap operation again within a predetermined period, the object control unit 195 causes the game character CA1 to execute the action a2 shown in the state (B) of FIG. Subsequently, when the input operation receiving unit 191 receives a flick operation within a predetermined period, the object control unit 195 causes the game character CA1 to execute the action a3 shown in the state (C) of FIG. The action a3 may be set so that the production is more flashy than the actions a1 and a2, or the attack power is increased. Further, instead of the flick operation for the action a3, the tap operation is continued three times, so that the object control unit 195 performs an action on the game character CA1 in which other effects are flashy or the attack power is large. You may let them. According to one embodiment, even in a game that causes the game character CA1 to execute a combo attack by a touch operation using the touch screen 130, the flow of the combo can be branched. Thus, by adopting a directional input operation for the attack operation during the combo attack, the user can cause the game character CA1 to attack so as to flow one after another by various operations. Therefore, the game preference is improved.

(Camera work during continuous attack)
Even during the continuous attack, the control unit 190 executes the process according to the flowchart of the attack operation shown in FIG. Whether or not the input operation is the first attack operation of the continuous attack is determined only when the second attack operation is input. Therefore, regardless of whether the tap operation is a normal tap operation or a continuous attack operation, the control unit 190 executes the process according to the flowchart for the attack operation shown in FIG. That is, the control unit 190 executes the process according to the flowchart at the time of the attack operation shown in FIG. 11 in response to the first tap operation that becomes a continuous attack operation afterwards.

  For this reason, as a step S40, when a continuous attack operation is received within a predetermined period, the control unit 190 sets the game character as the enemy character CA2 that is the target of the first attack action among the continuous attack operations within the predetermined period. I will turn CA1. In step S42, the control unit 190 controls the virtual camera VC so that the game character CA1 is photographed from a predetermined direction.

  And the control part 190 determines whether tap operation was performed before the predetermined period, when the tap operation after the 2nd time was performed. When the tap operation has not been performed before the predetermined period, the control unit 190 executes the process according to the flowchart for the attack operation shown in FIG. 11 for the second tap operation. In this case, the control unit 190 directs the game character CA1 to the enemy character CA2 to be attacked by the second tap operation. In step S42, the control unit 190 controls the virtual camera VC so that the game character CA1 is photographed from a predetermined direction.

  On the other hand, when the tap operation has been performed before a predetermined period, the control unit 190 does not execute step S42 in the flowchart for the attack operation illustrated in FIG. That is, the control unit 190 determines the shooting direction of the virtual camera VC determined based on the first attack operation within a predetermined period when the second and subsequent attack operations are performed within a predetermined period. Do not change while accepting consecutive attack operations. Thereby, even if the position of the enemy character CA2 changes due to the attack of the game character CA1, and the direction of the game character CA1 is changed accordingly, the shooting direction of the virtual camera VC is not changed. After the control unit 190 makes the user understand the direction of the character once, the control unit 190 provides the state of the continuous attack at a fixed angle, so that the user does not lose sight of the direction of the character. The character and the target character can be confirmed from various angles.

  Similarly, even when the attack operation during the combo attack includes a directional input operation, the control unit 190 determines the shooting direction of the virtual camera VC determined based on the first attack operation. It is not changed while accepting consecutive attack operations within a predetermined period. Hereinafter, an example in which the flick operation is included in the attack operation during the combo attack will be described in detail.

  FIG. 13 is a flowchart for explaining processing during a flick operation. The flowchart in FIG. 13 is a flowchart illustrating a process in which the control unit 190 advances the action game by executing the game program 151.

  In step S50, the control unit 190 determines whether an input operation has been accepted. The control unit 190 can accept a moving operation for moving the game character CA1 in the virtual space and an attacking operation for causing the game character CA1 to perform an attacking action as input operations.

  If it is determined that the input operation has been accepted (step S50: Yes), in step S32, the control unit 190 displays an operation object at the initial touch position (corresponding to the screen example (B) in FIG. 10). The object control unit 195 generates a circular operation object 300 in response to the input operation. The display control unit 196 displays the generated circular operation object 300 at the touch position.

  In step S54, the control unit 190 determines whether or not the input operation is a flick operation. The control unit 190 determines whether the operation is a flick operation using the history information of the touch screen 130 (see FIG. 4).

  If it is determined that the input operation is a flick operation (step S54: Yes), in step S56, the control unit 190 displays an operation object extending in the flick direction from the initial touch position.

  In step S58, the control unit 190 specifies the direction in which the game character CA1 is facing. For example, the storage unit 150 stores information indicating the direction in which the face of the game character CA1 is facing or the traveling direction of the previous movement operation. Control unit 190 selects the direction in which game character CA1 is facing from the directions indicated by the information stored in storage unit 150 based on the action executed by game character CA1 and the action from other objects. . Next, based on the selected result, the control unit 190 refers to the storage unit 150 and identifies the direction in which the game character CA1 is facing.

  In step S60, control unit 190 compares the direction of the flick operation with the direction in which game character CA1 is facing on the screen displayed on touch screen 130.

  In step S62, the control unit 190 causes the game character CA1 to perform an action corresponding to the comparison result in step S60. Details of this process will be described later with reference to the flowchart shown in FIG.

  In step S46, the control unit 190 ends the display of the operation object 300.

  On the other hand, if it is determined that the input operation is not a flick operation (step S54: No), in step S66, the control unit 190 causes the game character CA1 to perform an action corresponding to the input operation. In step S46, the control unit 190 ends the display of the operation object 300.

  When it is determined that the input operation is not accepted (step S50: No), or when the display of the operation object 300 is ended, the flowchart illustrated in FIG. 13 ends. Then, the control unit 190 executes the flowchart shown in FIG. 13 from the beginning until a predetermined condition is satisfied. Thus, a series of processing at the time of the attack operation is completed.

  FIG. 14 is a flowchart for explaining an operation process based on the flick operation shown in FIG. The control unit 190 causes the game character CA1 to perform an action according to the comparison result according to the flowchart shown in FIG.

  In step S70, control unit 190 determines whether or not a tap operation for performing an attack operation has been received within a predetermined period before the flick operation is received in step S50 shown in FIG.

  If it is determined that a tap operation for performing an attacking action has been received before a predetermined period of the flick operation (step S70: Yes), in step S72, the control unit 190 is directed to the game character CA1 in the direction of the flick operation. It is determined whether or not there is a predetermined relationship with the direction. The predetermined relationship may be such that, for example, the direction in which the game character CA1 is facing is an axis, and the direction of the flick operation is within a certain range from the axis to the left and right (for example, within 30 degrees and 45 degrees within each of the left and right). .

  If it is determined that the direction of the flick operation is included in a certain range of directions determined by the direction in which the game character CA1 is facing (step S72: Yes), the control unit 190 performs the previous attack action as step S74. The game character CA1 is caused to perform an attack action based on the corresponding operation being a tap operation and the current operation being a flick operation. As described above, when the game character CA1 continuously executes the attack action, the game character CA1 can execute different attack actions instead of causing the game character CA1 to execute the same attack action each time. Therefore, the attacking action becomes diverse. When step S72 ends, the flowchart shown in FIG. 14 ends.

  On the other hand, when it is determined that the direction of the flick operation is not in a predetermined relationship with the direction in which the game character CA1 is facing (No at Step S72), the control unit 190 performs an attack action on the game character CA1 as Step S76. The avoidance operation for moving in the direction of the flick operation is performed without performing the operation. Subsequently to step S78, the control unit 190 causes the game character CA1 to perform an attack action. In step S78, the attack action that the control unit 190 causes the game character CA1 to execute may be different from the attack action based on the tap operation. In this case, the attacking action by the game character CA1 becomes more diverse, and the game preference is improved. When step S78 ends, the flowchart shown in FIG. 14 ends.

  On the other hand, when it is determined that the tap operation for performing the attacking operation is not received before the predetermined period of the flick operation (step S70: No), in step S80, control unit 190 performs the avoidance operation on game character CA1. And do not execute the attack action. In step S82, the control unit 190 determines the orientation of the virtual camera VC based on the orientation of the game character CA1. When step S82 ends, the flowchart shown in FIG. 14 ends.

  In this way, the control unit 190 divides actions such as causing the game character CA1 to perform an attack action or an avoidance action in accordance with the direction in which the game character CA1 is facing and the direction of the flick operation. Can improve the taste of the game. In particular, it is possible to give diversity to the input operation for the attack target.

  Further, the control unit 190 determines the shooting direction of the virtual camera VC based on the first attack operation of the combo attack, and does not change the shooting direction during the combo attack. For this reason, after letting the user understand the orientation of the game character CA1 once, flicking operation becomes easy to input by providing the state of continuous attack at a fixed angle.

  Further, the flick operation is an operation that the user inputs intuitively and quickly in a scene where a quick operation is required during the game. In the present embodiment, since the attack action or the avoidance action can be selected according to the direction of the flick operation, the attack and the avoidance can be selected intuitively. Therefore, the game preference is improved.

(Modification 1)
When the camera placement control unit 194 receives a moving operation, the camera placement control unit 194 not only controls the virtual camera VC so as to track the game character CA1 from behind, but also controls the virtual camera VC so as to track the game character CA1 from another angle. May be controlled. For example, the camera arrangement control unit 194 may track the game character CA1 from behind. Alternatively, the camera arrangement control unit 194 may track the game character CA1 at a fixed angle. In the case of the fixed angle, the position of the game character CA1 within the field of view of the virtual camera VC is maintained even when the game character CA1 is changed from the state (A) to the state (B) in FIG. In this case, when the game character CA1 moves based on the moving operation, the camera arrangement control unit 194 captures the game character CA1 at a predetermined position in the field of view of the virtual camera VC and changes the movement amount and direction of the virtual camera VC. The position and orientation of the virtual camera VC are adjusted so that the amount of change is minimized.

  In addition, when accepting an attack operation, the camera arrangement control unit 194 not only controls the virtual camera VC so that the game character CA1 is photographed from behind, but also virtually captures the game character CA1 from other angles. The camera VC may be controlled.

  Furthermore, in the embodiment, the camera arrangement control unit 194 determines the shooting direction of the virtual camera VC based on the first attack operation of the combo attack during the combo attack, and fixes the shooting direction during the subsequent combo attack. However, the present invention is not limited to this. For example, when an attack operation (including a combo attack operation) is accepted, the camera arrangement control unit 194 may control the virtual camera VC so that the game character CA1 is always shot from behind. That is, during the combo attack, the shooting direction of the virtual camera is changed so as to maintain the shooting direction of the virtual camera VC determined based on the first attack operation (the direction in which the game character CA1 is shot from behind). to continue. In this case, the control unit 190 directs the game character CA1 to the enemy character CA2 to be attacked at the time of the attack in step S74 and step S78 in FIG. 14, and the shooting direction of the virtual camera VC according to the direction of the game character CA1. (The processing corresponding to steps S40 and S42 in FIG. 11 is performed). Thereby, in the battle scene, a game screen is provided in which the game character CA1 always faces the enemy character CA2 from the front and is always observed from behind the game character CA1. By using such camera work, the user does not lose sight of the character's direction, so that the operability can be improved even when the attack operation includes a directional input operation.

(Modification 2)
The operation object 300 indicating the operation result of the drag operation is not limited to the example shown in the state (B) of FIG. 7, and the operation result may be expressed using a plurality of objects.

(Modification 3)
In the states (A) to (D), the operation object 300 may not be displayed. That is, the end of the operation object 300 may not be changed, and only the starting point in the operation direction may be changed.

(Modification 4)
The operation included during the continuous hit operation has been described as an example of a flick operation, but may be a drag operation.

(Modification 5)
The mobile terminal 10 or the server 20 may execute all the game processes described above alone.
