Abstract

PROBLEM TO BE SOLVED: To especially provide technology enabling a game object in a RTS game to be operated in a flexible manner.SOLUTION: As a result of selection of a game object by touch operation on a touch panel to move a touch point, the game object is made to move in a straight line toward the moved touch point. This enables operation appropriate for a RTS game. Flexible operation of game objects during the progress of a game is made possible because a moving target (touch point) which is already determined can be changed afterward.

Description

  The present invention particularly relates to a game object control program and control method used in a game executed on a terminal having a touch panel.

  Conventionally, various games have been released in the game industry, and along with this, various game operation methods have been proposed. As one of such operation methods, a technique for directly operating a game object (for example, a player character) displayed on a touch panel with a user's finger or the like has been proposed, and a device for enjoying a game by improving usability is proposed. (For example, refer to Patent Document 1 and Patent Document 2).

JP 2007-26129 A JP 2009-18202 A

  The techniques disclosed in Patent Document 1 and Patent Document 2 both move the game object along a trajectory drawn on the touch panel by the player.

  However, for example, in a real-time strategy (hereinafter referred to as “RTS”) game, a strategy that emphasizes the “target (position to reach)” of the invasion rather than the “path” of the invasion. Is often set up. Therefore, in such a game, a function for invading at a shortest distance to a set target (position to be reached) is higher than a function for invading along a trajectory.

  Further, in the above RTS game, the game object operated by the player himself / herself is flexibly changed according to the current position of the game object operated by a third party other than the player himself / herself or the computer program and the movement destination predicted by the player. It is required to perform an operation to change the target to be moved (position where the user wants to reach). However, when a flexible operation of the game object is required, such as when the target (position to be reached) has been set as a target and the target (position to be reached) is to be changed to another target (position to be reached) while moving. Although there are many, neither patent document 1 nor patent document 2 is mentioned about such operation.

  As described above, the techniques disclosed in Patent Document 1 and Patent Document 2 are insufficient for performing operations suitable for the RTS game.

  Therefore, the present invention relates to a technique for improving usability, and in particular, provides a technique that enables flexible operation of a game object in an RTS game.

(First embodiment)
The game object control program according to the embodiment of the present invention constitutes a part of a game program executed on the terminal 1 as shown in FIG. An example of the game program is a so-called real-time strategy (hereinafter referred to as “RTS”) game. In the game, the game object control program according to the present embodiment can be operated by the player. It controls the movement of various game objects.

  As the terminal 1, for example, devices such as a mobile phone, a PDA, a smartphone, and a tablet computer are applicable, but are not limited thereto.

  As shown in FIG. 2, the terminal 1 includes a CPU 2, a main memory 3, an auxiliary memory 4, a transmission / reception unit 5, and a display unit 6 that are connected to each other via a bus. Of these, the main memory 3 is composed of, for example, a DRAM, and the auxiliary memory 4 is composed of, for example, an HDD. The auxiliary memory 4 stores a game object control program according to the present embodiment. The game object control program is expanded on the main memory 3 and executed by the CPU 2. In the main memory 3, data generated while the CPU 2 operates in accordance with the game object control program and data used by the CPU 2 are also temporarily stored. The transmission / reception unit 5 establishes a connection between the terminal 1 and the network under the control of the CPU 2.

  The display unit 6 in the present embodiment corresponds to the touch panel 60 described above, and includes a touch sensing unit 601 and a liquid crystal display unit 602 as shown in FIG. The control unit 603 transmits a display signal to the liquid crystal display unit 602 based on the operation signal transmitted from the touch sensing unit 601. Specifically, the touch sensing unit 601 receives an interactive touch operation (such as a physical contact operation on the touch panel 60) by the player, converts the operation into an operation signal, and transmits the operation signal to the control unit 603. The player's touch operation may be performed by the player's finger, a stylus, or the like. For example, a capacitance type can be adopted as the touch sensing unit, but the touch sensing unit is not limited to this. When detecting an operation signal from the touch sensing unit 601, the control unit 603 transmits a display signal for displaying a graphic (not shown) corresponding to the operation signal to the liquid crystal display unit (details will be described later). The liquid crystal display unit 602 displays a graphic corresponding to the display signal.

  As shown in FIG. 4, in the game object control program according to the present embodiment, the processing content of the control unit corresponding to the operation by the player is determined in advance. That is, when a touch operation (touch-on: an operation of bringing a finger or the like of the player into contact with the touch panel) is performed, the control unit 603 acquires the coordinate value of the point where the touch operation is performed and is selected by the player by the touch operation. Identify the game object. Thereafter, when the touch point is moved in a state where the touch state is maintained by the player (that is, the finger is not released from the touch panel 60 after the touch operation is performed), the coordinates of the touch point to be moved are acquired, The game object is moved linearly toward the touch point of the movement destination. Acquisition of the coordinates of the moving touch point is continuously performed at a predetermined timing during movement, and the moving direction of the game object is calculated each time (details will be described later). When the touch operation is completed (touch-off: when the player's finger or the like is released from the touch panel), the game object linearly moves to the point where the touch operation is completed (that is, the last touch point with the touch panel 60). Is done.

  Next, the relationship between the operation by the player and the control of the game object displayed on the actual touch panel 60 will be described with reference to FIGS.

In FIG. 5, the player touches on the game object 100 on A (X ₁ , Y ₁ ) on the touch panel 60 and moves it to B (X ₂ , Y ₂ ) and B ₁ (X _B1 , Y _B1 ). The movement of the game object 100 at this time is schematically shown. Incidentally, A, in the process of moving to B and B _1, the player's finger is still maintained the touch state (while being in contact with the touch panel 60). Specifically, when the player touches on the game object 100, the game object control program side determines that the game object 100 has been selected as a movement target by the user. Thereafter, when the player's finger is moved from A to B, a unit vector (direction vector) e ₁ is calculated from A coordinates (X ₁ , Y ₁ ) and B coordinates (X ₂ , Y ₂ ), The game object 100 is moved along the vector. Here, in the present embodiment, the game object 100 is started to move toward the moved touch point immediately after the movement of the touch point is detected. Therefore, from the moment when the player's finger moves away from A. The game object 100 starts moving so as to follow the finger (touch point). In the figure, when the player's finger is at B, the game object 100 has already advanced to the position B ′. In this state, when the finger of the player is moved from B to B _1, and B'coordinates (= current coordinates of the game object 100), a unit vector from the (current coordinates of the finger = player) of the coordinates B ₁ (Direction vector) e ₂ is calculated, and the game object 100 moves from B ′ to B ′ ₁ . That is, when the finger of the player is in the _{B 1,} the game object 100 is progressed already to the position of the _B'1.

  Note that the unit vector calculated from the movement direction of the game object 100, that is, the current coordinates of the game object 100 and the current coordinates of the player's finger, is repeatedly updated at predetermined intervals and updated as needed. The moving direction of the game object 100 (at that time) is determined. The Accordingly, the game object 100 always moves linearly toward the player's finger almost in real time (for example, every 0.2 seconds).

Next, referring to FIG. 6, the player places A (X ₁ , Y ₁ ), B (X ₂ , Y ₂ ), C (X ₃ , Y ₃ ), and D (X ₄ , Y) on touch panel 60. The control of the movement of the game object 100 will be described by taking as an example a case where the touch point is moved ₄ ) and the touch-off operation is performed at the last D (X ₄ , Y ₄ ). 6, the position _A of the player's _{finger, B, B 1, B 2} , C, C 1, C 2, D and the position A'of the game object _{100, B', B'1, B'} 2 , C ′, C ′ ₁ , C ′ ₂ , and D ′ correspond to each other. As shown in FIG. 6, when the player touches on A on the touch panel, the control unit (see FIG. 3) selects the game object 100 positioned at A (A ′) as the target of movement. Judge that. When the player moves the touch point from A to B (while keeping the touch-on state), the game object 100 follows the touch point immediately after the touch point starts to move, and finally toward B. Start moving linearly. As shown in the drawing, when the touch point is at B, the game object 100 has moved to the B ′ position. Thereafter, when the player moves the touch point toward B ₁ , B ₂ , and C toward C, the moving direction (= movement target) of the game object 100 changes from time to time B ₁ , B ₂ , and C, and B ′ It moves through the positions of ₁ , B ′ ₂ and C ′. Subsequently, when the player moves the touch point to C, C ₁ , C ₂ , D before the game object 100 moves to C, the moving direction (= movement target) of the game object 100 is C ₁ , C ₂ , changes from time to time, and moves through C ′ ₁ , C ′ ₂ , and D ′. When the player performs a touch-off operation at D, the point at which the touch-off operation is performed becomes the final movement direction (final movement target), and the game object 100 stops after moving from D ′ to D. As is apparent from FIG. 6, in the present embodiment, the game object 100 moves toward the touch point as a movement target, so that the movement locus of the touch point (ie, A, B, C, And the trajectory of movement of the game object 100 (lines smoothly connecting A ′, B ′, C ′, and D ′) do not necessarily match.

Note that, as shown in FIG. 7, a direction indication line 200 extending from the game object 100 toward the touch point may be displayed. Thereby, the player can grasp the moving direction and the moving end point of the game object 100. Since the direction of the tip of the direction indicating line 200 changes depending on the movement of the touch point, the display of the direction indicating line 200 when the touch point moves from E ₁ to E ₄ is displayed as shown in FIG. At this time, the game object 100 moves through E ′ ₁ , E ′ ₂ , E ′ ₃ , E ′ ₄ .

(Second Embodiment)
In the first embodiment described above, the point where the player performs the touch-off operation is the final movement target of the game object 100. However, if the final target point can be changed before the game object 100 completes moving to the final target, the game can be advanced more strategically. The game object control program according to the second embodiment of the present invention resets the final target point once set to another place before the game object reaches the final target (point where the touch-off operation is performed). Is something that can be done. Hereinafter, the description of the parts common to the first embodiment will be simplified, and only different parts will be described in detail.

In FIG. 8, the player selects the game object 100 at A (X ₁ , Y ₁ ) by touch-on operation, moves the touch point to B (X ₂ , Y ₂ ), performs touch-off operation, and then the game object 100. Touches the B (X ₂ , Y ₂ ) and moves the touch point to C (X ₃ , Y ₃ ) before completing the movement to B (X ₂ , Y ₂ ) that performed the touch-off operation. It shows the movement of the game object when operated. When the player performs a touch-off operation with B, the game object is located at B ′ and moving toward B. At this time, the game object 100 moves with B as a movement target. Here, when B is touched on and the touch point is shifted to C, the game object 100 is given a new movement target C and starts moving toward C.

  In the present embodiment, the movement target (the point where the touch-off operation has been performed) is moved by performing a touch-on operation. However, for example, when the direction indicating straight line shown in FIG. It is also possible to reset the movement target by touch-on the instruction line.

(Third embodiment)
In the second embodiment described above, when the movement target (the point where the touch-off operation has been performed) is moved, the game object 100 immediately moves toward the new movement target (see FIG. 8). (See Movement from B ′ to C ′). However, in the RTS game, there are cases where it is desired to move to the final target point via a plurality of points. According to the third embodiment, it is possible to reserve such a movement target. Hereinafter, the description of the parts common to the first embodiment will be simplified, and only different parts will be described in detail.

In FIG. 9, the player selects the game object 100 at A (X ₁ , Y ₁ ) by a touch-on operation, moves the touch point to B (X ₂ , Y ₂ ), and then performs a touch-off operation. Before the movement to (X ₂ , Y ₂ ) is completed, the B (X ₂ , Y ₂ ) is touched on, the touch point is moved to C (X ₃ , Y ₃ ), and the touch off operation is performed. Before the movement to C (X ₃ , Y ₃ ) is completed, the C (X ₃ , Y ₃ ) is touch-on operated, the touch point is moved to D (X ₄ , Y ₄ ), and the touch-off operation is performed. The movement of the game object is shown. When the player performs a touch-off operation with B, the game object is located at B ′ and moving toward B. At this time, the game object 100 is moving with B as the first movement target. Here, the second movement target C is given to the game object 100 by touching B and shifting the touch point to C (ie, moving the touch point to C to perform the touch-off operation). Thereafter, the game object 100 is given a third movement target D by touch-oning C and shifting the touch point to D (ie, moving the touch point to D to perform a touch-off operation). At this time, the game object 100 moves to D via B and C. Note that the coordinates of the movement target given to the game object 100 (that is, the coordinates of the point where the touch-off has occurred) are recorded in the reserved coordinate management table illustrated in FIG. 10, and the game object 100 moves to the reserved position in the table. When completed (that is, when the coordinates of the game object 100 match the reserved coordinates), the next movement target is given to the game object 100 and controlled to start moving.

  As described above, according to the present invention, it is possible to give an instruction on the touch panel so that the game object selected by the touch operation always moves (moves linearly) along the shortest path toward the touch point. Thereby, an operation suitable for the RTS game can be performed. In addition, since the movement target (touch point) once determined can be changed later, the game object can be flexibly operated while the game is in progress.
