Description

  The present invention relates to an object control program and an object control method, and more particularly to control for selecting a plurality of objects arranged in a virtual space.

  Conventionally, there has been provided a strategy game in which a plurality of friendly game objects and a plurality of enemy objects are battled in a virtual space (regardless of a turn system or a real time system). In recent years, with the widespread use of terminals equipped with a touch panel, intuitive operations have become possible in strategic games executed on such terminals.

  In the above-mentioned strategy game, for example, there are cases where it is desired to select a plurality of teammate objects and perform the same action (attack, movement, etc.) on the selected objects. When a plurality of objects are selected on a terminal having the touch panel described above, a method of touching each object to be selected is often adopted.

  On the other hand, as another method for quickly selecting a plurality of objects, an object surrounded by a touch pen or the like is determined as a selected object (see, for example, Patent Document 1), and a straight line drawn with a touch pen or the like is used as a diagonal line. A method of displaying a rectangle and determining an object included in the area as a selected object has also been proposed (see, for example, Patent Document 2).

  A smartphone, which is an example of a terminal including the touch panel described above, is designed to have a size that can be operated with one hand when held in the vertical direction. Accordingly, as shown in FIG. 21, the user can operate the touch panel with the thumb while holding the vertical casing with one hand. However, as can be understood from FIG. 21, the movable range of the thumb is extremely small when the hand is held. Therefore, depending on the method of selecting an object by touching each object, it is inconvenient because the smartphone needs to be changed in order to select an object that cannot be reached by the finger. In addition, there is a problem that the size of the movable range of the thumb depending on the size of the user's hand affects the advantage / disadvantage in game play. Moreover, since the operation method currently disclosed by patent document 1 and patent document 2 needs to operate with the other hand, hold | maintaining an apparatus with one hand, this is the strategy performed with the said smart phone When applied to a game, the user cannot enjoy the special merit of a smartphone that can be operated with one hand.

  Furthermore, in a terminal with few operation variations such as a terminal having a touch panel, another function (for example, an object status display function) is already assigned to the main operation such as a touch operation and a swipe operation. There is. In such a case, a method of implementing a special mode such as an object selection mode and selecting an object after switching the mode is also conceivable. However, such a method not only complicates the structure of the object control program, but also causes problems such as the mode switching operation impairing the real-time feeling of the game and the operation becoming complicated for the user. Note that this problem may also occur in terminals other than the terminal having a touch panel (so-called video game machines, PC game machines, arcade game machines, etc.).

  Therefore, the present invention aims to provide a technique for maintaining the advantage of a smartphone that can be operated with one hand and enabling selection of a plurality of objects without causing the above-described problems, thereby improving usability. And

(First embodiment)
An object control program and an object control method according to the first embodiment of the present invention are executed and executed in a terminal 1 as shown in FIG. The terminal 1 includes a touch panel 2 and is of a size that can be held and operated with one hand as illustrated in FIG. According to the control of the game object according to the present embodiment, the user can control (select) the object placed in the game virtual space while holding the terminal 1 with one hand. Note that the object control program according to the present embodiment constitutes a part of a game or the like executed on the terminal 1.

  The terminal 1 may be, for example, a device such as a mobile phone, a PDA, a smartphone, or a tablet computer, but preferably has a size that can be held and operated with one hand as described above.

  As shown in FIG. 2, the terminal 1 includes a CPU 3, a main memory 4, an auxiliary memory 5, a transmission / reception unit 6, a display unit 7, and an input unit 8 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 an object control program according to this embodiment. The 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 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 10 and the network under the control of the CPU 2. The input unit 8 detects an operation on the touch pal 2 by the user and detects that an operation has been performed on the terminal.

  The touch panel 2 according to the present embodiment is provided with the functions of the display unit 7 and the input unit 8 at the same time. That is, as shown in FIG. 3, the touch panel 2 includes a touch sensing unit 80 that functions as the input unit 8 and a liquid crystal display unit 602 that functions as the display unit 7. The touch panel 2 displays an image on the liquid crystal display unit 70 under the control of the control unit 30 (CPU 3), accepts an interactive touch operation (such as a physical contact operation on the touch panel 2) by the touch sensing unit 80, and responds to it. The graphic to be displayed is displayed on the liquid crystal display unit 70. Specifically, the touch sensing unit 80 outputs an operation signal corresponding to the touch operation by the user to the control unit 30. The user's touch operation may be performed by the user's finger, a stylus, or the like. The touch sensing unit 80 may be, for example, a capacitance type, but is not limited to this.

  The object control program according to the present embodiment is used to select a plurality of objects arranged in a virtual space, particularly in a strategy game or the like, and functions as a kind of interface. That is, as shown in FIG. 4, three objects 100 are displayed on the touch panel 2, and the object 100 is selected by an operation with a user's finger 90. Here, as an example of the object 100, any in-game object used for a strategy game such as a humanoid character, a moving body, a facility / building, etc. can be applied. Further, the present invention can be applied regardless of whether or not there is a movement in the game or an enemy. When the touch panel 2 receives a long press operation (an operation for maintaining a contact state for a predetermined time) by the user's finger 90, the object control program performs a process of displaying the circular selection area 200 defined by the boundary line 202. Then, control is performed to enlarge the area (specifically, radius) of the selection region 200 according to the long press time. Further, when the user's finger 90 is released from the touch panel 2 (that is, when the long press operation is finished), the object control program selects the object 100 located in the selection area 200 with the selected object 102 selected by the user. It recognizes that there is, and recognizes that the object 100 located outside the selected area 200 is an unselected object 104 that has not been selected by the user. Hereinafter, a specific configuration and process flow of the object control program according to the present embodiment will be described.

  5 to 7 are management tables that are referred to by the object control program according to the present embodiment when it is executed.

As shown in FIG. 5, in the object management table, object names “obj — 001” to “obj — 003” for specifying the object 100 (see FIG. 4) and coordinates “P ₁ ” indicating the current position of each object 100 are displayed. (X ₁ , y ₁ ) ”to“ P ₃ (x ₃ , y ₃ ) ”are recorded in association with each other. The coordinates are coordinate information in the virtual space, and an object is displayed at a corresponding position in the virtual space based on the coordinate information. In addition, what is necessary is just to apply the predetermined | prescribed thing represented by the orthogonal coordinate system, the polar coordinate system, etc. as coordinate information as needed.

  As shown in FIG. 6, in the area information management table, the center coordinate (that is, the coordinate of the touch point by the user), “r” that is the current value of the radius that expands according to the long press time, and the radius The change speed (enlargement speed) is recorded in association with it. Among these, the change speed is preset. The object control program displays / draws the selected area 200 (see FIG. 4) based on the area information management table.

As shown in FIG. 7, the selected object management table records the objects included in the above-described selection area (that is, the object 102 selected by the user's long press operation: see FIG. 4). In the illustrated selected object management table, object names “obj — 001” and “obj — 002” that specify two objects 102 located in the selection area 200 of FIG. 4 are recorded.

Next, a processing flow of the object control apparatus according to the present embodiment will be described with reference to FIGS. Among these, in FIGS. 9 to 11, only the center points P _{1 to} P _{3 of} each object 100 are shown. As shown in FIG. 8, when the user performs a long press operation on a point other than the object 100 (for example, an arbitrary point on the game field), the touch sensing unit detects a touch operation (SQ1), and the control unit performs the touch operation. The coordinates of the point are acquired from the position of the operated point (point C in FIG. 9) and recorded in the area information management table (FIG. 6) (SQ2). At the same time, the control unit measures the time during which the touch operation is performed (SQ3), and updates the value of the radius of the selected region each time based on the time and the change speed of the selected region (see FIG. 6) (see FIG. 10 and FIG. 10). (See FIG. 11). In this embodiment, the radius value update frequency (calculation frequency) is set to a frame rate (for example, 300 fps) or more. The control unit displays a circular selection area on the liquid crystal display unit based on the center coordinates and the updated radius (SQ5: see FIG. 11). Here, the shape of the selection region 200 shown in FIG. 11 is, for example, a circle represented by the following mathematical formula.

Subsequently, the control unit obtains the position coordinates of the object (P _{1 to} P _{3 in} FIG. 11) by referring to the object management table (see FIG. 5) (SQ6), and uses the area information management table (see FIG. 6). The center coordinates of the region (the coordinates of the point C in FIG. 11) are acquired with reference to (SQ7). In FIG. 11, for example, whether or not the object P ₁ exists in the selection region 200 may be determined by determining whether or not the distance between P ₁ C is equal to or less than the radius r using, for example, the following mathematical formula. The same applies to the other objects P ₂ and P ₃ . The control unit calculates whether the distance between the center coordinate C and each object 100 is equal to or less than the radius r at a predetermined frequency (SQ8). Thus, in the present embodiment, whether or not the object 100 exists in the selection area 200 is determined by whether the center (P _{1 to} P ₃ ) of the object 100 exists in the selection area 200. Judging by. Therefore, even if a part of the object 100 overlaps the selection area 200, if the center is not located in the selection area 200, the object 100 is not determined as the selected object 102.

Based on the above calculation, the control unit registers an object (P ₁ and P ₂ in FIG. 11) whose distance between the center coordinate C and each object 100 is equal to or less than the radius r as the selected object 102 in the selected object management table. (Update) (SQ9). At this time, the selection effect 400 is displayed on the selected object 102. Thereby, the user can know which object 100 the selected object 100 is. When it is detected in the touch sensing unit that the touch operation has been released (the user's long press operation has been completed) (SQ11), the processing of the control unit is terminated. After that, the control unit may collectively perform predetermined processing (movement, item use, attack instruction, etc.) on the selected object 102.

(Second Embodiment)
Subsequently, the control of the object control program according to the second embodiment of the present invention will be described with reference to FIGS. The object control program according to the second embodiment includes a control for adding an unselected object to a selected object after the processing of the object control program according to the first embodiment is completed, Control to cancel the selection of the object. Any control is performed after the processing of the object control program according to the first embodiment is completed. Therefore, the description about the part already demonstrated is abbreviate | omitted, and only the point which needs to be newly demonstrated in 2nd Embodiment is mentioned.

  As shown in FIG. 13, when the object 100 located outside the selection area 200 is touched while the selected object 102 is displayed, the object 100 is displayed in the selected object management table (see FIG. 7). Added. Similar to the first embodiment, the selection effect 400 is also displayed on the object 100. On the other hand, as shown in FIG. 14, when the selected object 102 is displayed and the object 100 located in the selection area 200 is touched, the object 100 is selected as a selected object management table (see FIG. 7). Deleted from. At the same time, the selection effect 400 is also hidden.

  As shown in FIG. 15 (SQ1 to SQ12 are the same as those in FIG. 8), when a user's touch operation is detected (SQ13), the control unit refers to the selected object management table (SQ14). Then, it is determined whether the touched object is the selected object 102 or the unselected object 104 (SQ15). As shown in FIG. 13, when the touched object 100 is an unselected object, the object 100 is registered in the selected object management table (see FIG. 7) (SQ16), and the selection effect 400 is displayed. (SQ17). On the other hand, as shown in FIG. 14, when the touched object 100 is a selected object, the object 100 is deleted from the selected object management table (see FIG. 7) (SQ16) and displayed. The selected effect 400 is hidden.

(Third embodiment)
Subsequently, the control of the object control program according to the third embodiment of the present invention will be described with reference to FIGS. The object control program according to the third embodiment moves selected objects all at once after the processing of the object control program according to the first embodiment is completed. Therefore, the description of the parts that have already been described is omitted, and only the points that need to be newly described in the third embodiment are mentioned.

  As shown in FIG. 16, when a point Q that is desired to be a movement target (target point) is touched in a state where the selection effect 400 is displayed on the selected object 102, the selected object 102 The movement toward the target point Q is started. At this time, a direction display 600 indicating the moving direction of the object 100 may be displayed.

  Note that any of the selected objects 102 may be touch-operated, and the swipe operation may be performed toward the target point in that state (while maintaining the contact state). In this case, the end point of the swipe (that is, the point where the contact state is released) is recognized as the moving point.

(Fourth embodiment)
Subsequently, the control of the object control program according to the fourth embodiment of the present invention will be described with reference to FIGS. The object control program according to the fourth embodiment hides the selection area 200 described above and displays an enlarged area 800 larger than the selection area 200 outside the selection area 200. The determination as to whether or not the object 100 is located in the selection area 200 is the same as that already described, and thus the description thereof is omitted.

As shown in FIG. 19, the selection area 200 in the present embodiment is not displayed, and an enlarged area 800 having a larger radius than the selection area 200 is displayed outside the selection area 200. The centers of the selection area 200 and the enlargement area 800 coincide, and the radius of the enlargement area 800 is larger than the radius of the selection area 200 by “i”. Here, “i” is the radius of the object 100. Note that. When the object 100 is a polygon or the like, the distance between the center of gravity and the farthest part (or the nearest part) may be used. According to this structure, (the object 100 having center coordinates P ₂₎ object 100 contained entirely in the enlarged region 800 that is visible to the user while it is determined that the Selected object 102, enlarged region The object 100 that is only partially included in 800 (the object 100 having the center coordinate P ₁ ) is determined as the unselected object 104. Thereby, when viewed from the user, it is possible to produce an effect such that only the object 100 completely included in the displayed circle (enlarged region 800) becomes the selected object 102.

  As shown in FIG. 20, the object control program refers to the enlarged area information management table recorded by associating the center coordinates (= the center coordinates of the selected area 200) and the radius, and the user control program is similar to the selected area 200. The size (area) is enlarged according to the long press operation and in conjunction with the selection region 200.

  The first to fourth embodiments of the present invention have been described above. However, as other embodiments that can be combined with these embodiments, the fifth to eighth embodiments will be described below. The embodiment will be described. Since the fifth to eighth embodiments are configurations that can be added to the first to fourth embodiments described above, in the following description, the first embodiment will be described. A description of the embodiment to the fourth embodiment is omitted.

(Fifth embodiment)
In a state where the selected object 102 is displayed (see FIG. 12), when a touch operation is performed on a part other than the selected object 102 and the unselected object 104 (for example, an empty part in the virtual space), all selections are made. The completed objects 102 may be collectively excluded from the selected object management table (see FIG. 7). Thereby, when the object 100 which is not desired is recognized as the selected object 102, it can be re-selected immediately.

(Sixth embodiment)
Although the selection area described above is circular, for example, the selection area may have an appropriate shape according to the situation depending on the position of the virtual camera displaying the virtual space. For example, when the virtual space is displayed obliquely from above, the selection area 200 may be elliptical (see, for example, display on the main screen 700 in FIG. 18).

(Seventh embodiment)
Moreover, although the changing speed of the selection area 200 that expands according to the time of the long press operation is constant (see FIG. 6), it may be reduced as the operation time elapses. That is, in the present embodiment, the selection operation feeling may change depending on the enlargement speed of the circle (selection region 200). Specifically, when the enlargement speed is fast, many units can be selected quickly, but it is difficult to make fine adjustments, and when the enlargement speed is slow, it is easy to select as intended, but it takes time to select the necessary units. It will take. Therefore, in the present embodiment, immediately after the long pressing operation of the circle (selection area 200), the time until the selection is made by increasing the enlargement speed, and then the enlargement speed is made slower, Control is made so that unintended selections are not made.

(Eighth embodiment)
As shown in FIG. 18, in addition to the main screen 700 that displays the virtual space, when the reduced screen 710 that displays the entire virtual space and displays the entire virtual space is displayed on the touch panel 2, the main screen 700 is displayed. Simultaneously with displaying the selection area 200, a reduction selection area 200 ′ corresponding to the selection area 200 may be displayed in the reduction screen 710. For example, when the position and angle of the virtual camera on the main screen and the reduced screen are different, such as when the main screen is displayed obliquely from above and the reduced screen is displayed from directly above, the selection area 200 is set more accurately. The selection of the object 100 can be facilitated.
