Description

  The present invention relates to a method and a program for selecting an object displayed on a screen of an information processing apparatus such as a smartphone.

  In recent years, the popularity of puzzle games that can be executed by information processing apparatuses such as mobile terminals, tablet terminals, and PCs (Personal Computer) terminals has increased. For example, since it is a simple rule to connect and erase objects with the same pattern from objects such as panels arranged on the screen, anyone can easily play.

  Generally, when selecting an object in a conventional puzzle game, it is determined whether the user has selected (tapped) an area (determination area) set for each object, and if the determination result is “positive” Confirm the object selection. In many cases, so-called hit determination is performed.

  For example, in a soccer game, it is easy to select a selection candidate game character by changing the determination area of the selection candidate game character based on the positional relationship between the selected game character and the selection candidate game character. Is disclosed (see Patent Document 1).

(Principle of the invention)
As shown in FIG. 1, the present invention is applied to, for example, a puzzle game executed by an information processing apparatus 1 such as a smartphone. The screen display example of the information processing apparatus 100 includes a play area 101 and an information display area 102. The play area 101 is an area where the user actually plays a game, and a plurality of objects such as a panel with a color or a pattern are arranged thereon. In the information display area 102, a score obtained by the game is displayed. When the user taps on the screen with a finger to select the same kind of objects from a plurality of objects arranged in the play area 101, points corresponding to the number of selected objects as shown in the information display area 102 Can be obtained.

  A basic method of object selection in the present invention will be described with reference to FIG. FIG. 2 is an enlarged view of a part of the play area 110. A base point object is indicated by a double line, a selectable candidate object substantially adjacent to the base point object is indicated by a solid line, and a non-selectable object is indicated by a broken line. Show. Here, the base point object refers to an object that is first selected by the user, but may be an object that is designated in advance in the game. The conditions as candidate objects are, for example, “the same color and shape as the base point” (conditions for selecting the same color), “adjacent to the base point” (conditions for tracing adjacent panels), and “ “Not yet selected” (conditions for one-stroke writing) or “what was the base point immediately before the current base point” (conditions for cancellation). That is, the user first selects a base point object, and then selects an object of the same type as the base point object, whereby predetermined processing is performed in the information processing apparatus. The predetermined process may be, for example, a process in which a privilege such as points or items is given according to the number of selected objects of the same type in the game. The candidate object can be said to be an object that is highly likely to be selected by being traced by the user's finger or tapped after the base object. The shape and arrangement of the object are examples and can be arbitrarily changed. For example, the object may have a hexagonal shape called Hex, a quadrangular shape such as a rhombus, or a triangular shape. Further, they may be arranged apart from each other as shown in FIG. 1 or may be arranged in close contact with each other.

  Candidate objects are determined from objects that are substantially adjacent to the base point object when the base point object is selected by the user and the designated coordinates are input. Thereafter, a vector Ci (first vector) from the base point object to each candidate object i and a vector P (second vector) from the base point object to the designated coordinates are set, and the vector that minimizes the angle θi formed with the vector P The candidate object i having Ci is determined as the selected object. Note that the two points and coordinates at both ends forming the vectors Ci and P may be the center point of each object or the center of gravity.

  Conventionally, it is necessary to set a determination area in advance for selecting a candidate object, and depending on the shape and arrangement of the object, a large amount of calculation is required for setting and determining the determination area. However, by adopting the above-described mode, it is not necessary to set a determination area in advance for selecting a candidate object, and the amount of calculation is smaller than setting a determination area having a complicated shape. In addition, since the determination area corresponding to the candidate object is wider than the object shape, it is not necessary to press the candidate object itself if the direction of the designated coordinates is some extent. Therefore, compared to the conventional method of setting a determination area for each object, it is difficult for a slip-through to occur, and the operability for the user can be improved.

(Embodiment)
FIG. 3 is a diagram illustrating a configuration example of an information processing apparatus that executes a game program according to an embodiment of the present invention. The information processing apparatus 100 includes an input device 11, an output device 12, a communication device 13, a control unit 14, and a memory 15. In the following, the information processing apparatus 100 is assumed to be a feature phone, a smartphone, a tablet terminal, a PC (Personal Computer) terminal, a so-called home game machine or a portable game machine (hereinafter referred to as a user terminal), and a server. The processing on the game application downloaded from the device will be described. However, the present invention is not limited to this, and the present invention can be similarly applied to a so-called browser game in which a game application is executed in the server device. In that case, the server device receives an operation of the user terminal by the user via the network, and controls the processing result executed in the server to be displayed on the screen of the user terminal according to the received operation content. Needless to say, you can do it.

  The input device 11 includes a keypad having a group of buttons, a keyboard, a mouse, and the like. The input device 11 accepts an object selection operation by the user or an input operation of various types of information, and sends it to the control unit 14.

  The output device 12 includes a screen interface for displaying various screens such as a game screen, a speaker for outputting sound, and the like. Note that the input device 11 and the output device 12 can be integrated by a touch panel in which a position input device such as a touch pad and a display device such as a liquid crystal panel are combined.

  The communication device 13 is a communication interface for data communication with an external device, and includes a wireless module that can be wirelessly connected to a wireless base station such as a mobile phone or a wireless LAN. A game program downloaded from an application providing platform (not shown) and various information transmitted from a server (not shown) providing a game service are received. Further, various information is transmitted to the server in accordance with the user input operation received by the input device 11. The application providing platform may be integrated with the server or provided separately.

  The control unit 14 includes an input acquisition unit 141, a game processing unit 142, and a display control unit 143. The input acquisition unit 141 acquires user operation information input via the input device 11. The game processing unit 142 activates a game program stored in the memory 15, manages the progress of the game, and performs an object selection process described later. Further, the game processing unit 142 accesses the server via the communication device 13 as necessary, and stores various data derived from the progress of the game in the memory 15. The display control unit 143 performs control to display a predetermined image on the screen of the output device 12 according to the progress of the game or according to the instruction of the game processing unit 142.

  The memory 15 is used to store a game program downloaded from the application providing platform when installing an application. In addition, various information from the server received by the communication device 13, various data derived from the progress of the game, and the like are stored. Further, the memory 15 stores the arrangement and coordinates of each object appearing in the following description, the calculated vector, the angle, the selected candidate object, and the selected object by accessing the control unit 14. The stored information is read and output to the control unit 14.

  Here, the object selection process performed by the game processing unit 142 will be described with reference to the flowcharts of FIG. 2 and FIG. Prior to the processing of FIG. 4, it is assumed that a game program is activated and a plurality of arbitrarily selectable objects are arranged on the screen of the output device 12.

  When the user inputs a base point on the screen via the input device 11 (step S1), the game processing unit 142 determines / specifies the base point object 0 including the base point position coordinates (step S2). When the base object is determined, the display mode may be changed so that the user can visually recognize that the base object is the base object.

  Next, when an area different from the area of the base object on the screen is tapped by the user via the input device 11 and the position is recognized and input as the designated coordinate p (step S3), the game processing unit 142 is performed. Identifies objects that are substantially adjacent to the base object as candidate objects 1, 2,..., N, and vectors C1, C2,..., Cn from the center c0 of the base object to the centers c1, c2,. Each (first vector) is set (step S4). Here, the candidate object is, for example, an object having the same color or pattern as the base object.

  Furthermore, the game processing unit 142 sets a vector P (second vector) that goes from the center c0 of the base object to the designated coordinate p (step S5). .., Cn (first vector) set for each candidate object, and angles θ1, θ2,..., Formed by a vector P (second vector) directed from the center c0 of the base object to the designated coordinate p. θn is calculated respectively (step S6). The game processing unit 142 determines a selection object from among the candidate objects so as to satisfy the condition that the calculated angle is the minimum (step S7).

  For example, referring to FIG. 2, vectors C1, C2, C3 from the center c0 of the base object to the centers of candidate objects 1 to 3 are set. If the angles θ1, θ2, and θ3 formed by the vectors C1, C2, and C3 and the vector P are set, the candidate object 2 having the minimum angle θ2 can be determined as the selected object.

  As described above, according to the above-described embodiment, it is not necessary to set a determination area in advance for a selection candidate object as in conventional object selection, so that a selected object can be appropriately determined with a small amount of calculation. It becomes like this. As a result, even if the user inputs quickly, the determination area is not squeezed or slipped through, and the object can be appropriately selected as the user desires.

  Further, the smaller the angles θ1, θ2,..., Θn formed by the vectors C1, C2,..., Cn and the vector P, the more accurately the user indicates the center of the object. For example, when a user is chased by time and selects an object quickly in a game, it is assumed that the instruction becomes complicated and the indicated coordinates greatly deviate from the center of the object. Therefore, when the accuracy of the instruction in object selection is emphasized, the game processing unit 142 can give more points on the game as the angle between the vector of the selected object and the vector P is smaller. It is.

  The present invention is not limited to the above embodiment. Hereinafter, a modified example of the object selection method will be described.

(Modification 1)
In the first modification, the game processing unit 142 determines that only the designated coordinates are newly input after determining the selected object in step S7 in FIG. 4, and a plurality of objects are located between the base point object and the designated coordinates. The determined selected object is regarded as the next base point object, and a plurality of selected objects are determined by repeating the processing of each step of FIG. For example, as shown in FIG. 5, it is assumed that a plurality of objects having the same pattern and color as the base object (objects indicated by solid lines in FIG. 5) are arranged between the base object and the designated coordinates. In such a case, the game processing unit 142 moves the base point in the order of the objects 1 to 11 by continuing to indicate the specified coordinates (the finger tapping the screen is kept on the screen without releasing it). Each time the base object changes, a plurality of objects are selected by processing steps S4 to S7 in FIG. In this manner, since the user automatically selects the objects between the base point object and the designated coordinates, it is possible to reduce anxiety factors such as selection mistakes, and to facilitate the progress of the game. be able to.

(Modification 2)
In FIG. 5 described above, when the object 11 is selected after the object 10, the change in the angle formed by the designated coordinates is larger than the selection from the objects 8 to 9. Therefore, in the second modification, the game processing unit 142 controls the determination of the selected object by setting the upper limit value of the angle θi. For example, as shown in FIG. 6, when the angle formed by the vector C11 and the vector P exceeds the upper limit value, the object 11 can be controlled not to be selected. Thereby, it can be excluded that an object is selected against the user's intention.

  Further, the selection of the object may be canceled by the user selecting the selected object again. However, it is not desirable that the object selection is canceled against the user's intention. Therefore, as shown in FIG. 7, the game processing unit 142 sets an upper limit value for the angle θ2 of the object 2 that has already been selected, and if θ2 exceeds the upper limit value, the selection of the object 2 is It can be determined that the object 4 is selected without being canceled. Thus, by setting an upper limit value for the angle of a specific object and performing angle determination more strictly than a normal object, it is possible to appropriately determine the intention of the user operation.

(Modification 3)
Modification 3 proposes a technique for facilitating selection of a specific object. Specifically, the game processing unit 142 sets a plurality of vectors for a plurality of position coordinates of the candidate object from the base object for a predetermined candidate object, thereby comparing a specific object with other candidate objects. It can be made easy to select. That is, a plurality of base points of the vector formed between the candidate object and the base point object are set instead of one. For example, as shown in FIG. 8, when the vector C1 is set for the object 1 and the vectors C21 and C22 are set for the object 2, the angle θ21 is the smallest among the angles θ1, θ21, and θ22 formed with the vector P. Object 2 will be selected. Thus, it becomes possible to control a predetermined object easily.

(Modification 4)
Modification 4 is a method of setting a specific object to be easily selected from a plurality of candidate objects or setting a specific object to be difficult to select when there are a plurality of candidate objects. Specifically, the game processing unit 142 controls the selection of the selected object by adding an offset (also referred to as weighting) to the angle calculated for each candidate object. For example, as shown in FIG. 9, predetermined offset values (offset> 0, for example, offset1 = “1” for object 1 and offset2 = “2” for object 2) are assigned to each of object 1 and object 2. The object 1 is weighted with an angle θ1 + offset1 and the object 2 is weighted with an angle θ2 + offset2. By this weighting, even when the angle θ1 = the angle θ2, the object 1 is selected as θ1 + offset1 <θ2 + offset2. In this way, it is possible to control the predetermined object so that it is easy to select or difficult to select depending on the attribute of the object, for example.

  Further, as shown in FIG. 10, the game processing unit 142 sets the weights for the objects 1 and 2 to w1 and w2, respectively, and the angle formed by the vector C1 and the vector C2 is set to a ratio of w1: w2. The object can be selected by comparing the line D to be internally divided with the position of the designated coordinate P. For example, the angle between the Y axis forming the coordinate axis on the screen and the designated coordinate P is θp, the angle between the Y axis and the vector C1 is θc1, the angle between the Y axis and the vector C2 is θc2, and two or more candidates When there is a vector C1, C2 in the vicinity so that θc1 <θp <θc2, and the weight of C1 is w1 and the weight of C2 is w2, the angle formed by the vector P and the vector C1 is θp −θc1, the angle formed by the vector P and the vector C2 is θc2−θp, and the angle formed by the line D and the vector C1 that internally divides the angle formed by the vector C1 and the vector C2 by w1: w2 is (θc2− θc1) * (w1 / (w1 + w2)). Here, the game processing unit 142 may adopt the object 1 when θp−θc1 <(θc2−θc1) * (w1 / (w1 + w2)) is satisfied.

  In the above, this invention was demonstrated based on each embodiment. The present invention is not limited to the contents of the embodiments and examples described above, and various modifications can be made within the scope of the gist of the present invention. Those skilled in the art will understand that the above-described embodiments are exemplifications, and that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are also within the scope of the present invention. .
