The present invention relates to an electronic game using a display capable of displaying two or more dimensions. In particular, the present invention relates to an apparatus for mounting a game that progresses using coordinate data input by a user's touch operation on a touch panel, a control method thereof, and a control program.

A trajectory information processing device is known that acquires input information intended by a person from the trajectory of a spiral figure (see, for example, Patent Document 1).
The device described in Patent Document 1 removes the closed curve and the curve preceding the closed curve from the trajectory after acquiring the closed curve connecting the intersection start point to the intersection end point when the input trajectories intersect. The same processing is repeated with the intersection end point as the start point of a new locus.

JP, 2007-215647, A

The device described in Patent Document 1 presumes that a plurality of closed figures are formed one by one, and every time a closed figure is detected, all trajectory information up to the end point of the closed figure is removed.
Therefore, when a plurality of closed figures are nested, part of the closed figures cannot be detected.

An object to be solved by the present invention is to detect a plurality of closed figures without omission when a plurality of closed figures drawn by a user by a slide operation are nested.

In order to solve the above problems, the “information processing device” according to one aspect of the present invention overlaps with the first position from the first position on the track each time the tracks indicated by the coordinate information group of the processing target intersect. A specifying unit that specifies coordinate information that forms a closed figure that connects up to a second position on the trajectory, and a new coordinate information group excluding the coordinate information that is specified by the specifying unit become the processing target. Setting means for setting.
In order to solve the above-mentioned problems, the “control method for an information processing device” according to one aspect of the present invention provides a method for controlling a first position on a locus every time a locus indicated by a coordinate information group of a processing target intersects. A specific step of specifying coordinate information that forms a closed figure connecting up to a second position on the locus that overlaps the position, and a new coordinate information group from which the coordinate information specified in the specific step is excluded is the processing target. And a setting step of setting to become.
In order to solve the above-mentioned problems, the “control program” according to one aspect of the present invention is configured such that each time a locus indicated by a coordinate information group of a processing target intersects, the first position on the locus overlaps with the first position. A specific function that specifies coordinate information that forms a closed figure that connects up to a second position on a locus, and a new coordinate information group that excludes the coordinate information that is specified by the specific function is set as the processing target. And a setting function to be performed by the computer of the information processing apparatus.
In order to solve the above-mentioned problems, a “computer-readable recording medium” according to one embodiment of the present invention is provided with a “computer-readable recording medium” from a first position on the locus every time a locus indicated by a coordinate information group to be processed intersects. A specific function that specifies coordinate information that forms a closed figure that connects up to a second position on the locus that overlaps the position, and a new coordinate information group that excludes the coordinate information that is specified by the specific function is the processing target. The control program that causes the computer of the information processing apparatus to realize the setting function to be set is recorded.

The following technical limitations may be added to the "information processing device" of the present invention. Further, the same technical limitation may be added to the “control method” and the “control program” of the present invention.
For example, the coordinate information group holds the order of coordinates, and the setting unit newly sets the coordinates immediately before the first position and the coordinates immediately after the second position to be directly or indirectly ordered. A technical limitation that a group of different coordinate information is set as the processing target may be added.
At this time, any of the following technical limitations may be added.
The coordinate information includes next coordinate information, and the setting means rewrites the next coordinate information of the coordinates immediately before the first position to the coordinates immediately after the second position.
The coordinate information includes next coordinate information, and the setting means rewrites the next coordinate information of the coordinate immediately before the first position into the coordinate of the intersection position and the next coordinate information of the coordinate of the intersection position. Rewrite to the coordinates immediately after the second position,
The coordinate information group is already aligned, and the setting means separates the coordinate information specified by the specifying means from the coordinate information group to be processed. At this time, the setting means may insert the coordinate information of the intersection position between the coordinate information of the coordinates immediately before the first position and the coordinate information of the coordinates immediately after the second position.

The following technical limitation may be further added to the “information processing apparatus” to which the above technical limitation is not added and the “information processing apparatus” to which any one of the above technical limitations is added. Further, the same technical limitation may be added to the “control method” and the “control program”.
For example, when the internal areas of the two closed figures respectively indicated by any two coordinate information specified by the specifying means at least partially overlap, a determining means for determining the content of the effect generated in association with the overlapping area. The technical limitation of further provision may be further added. At this time, there is further added a technical limitation that the determining unit determines the content of the effect in consideration of the ratio of the overlapping region to at least one of the internal regions of the two closed figures. Good. In these cases, it is possible to further add a technical limitation that the determining unit determines the content of the effect only when an object exists in the overlapping area.

In the present invention, “coordinate information” refers to information specifying a position (coordinates) on a plane.
In the present invention, the “coordinate information group” refers to a set of coordinate information. The coordinate information group includes at least one unit of coordinate information.
In the present invention, the “intersection position” means the position where the loci intersect. When a certain locus intersects at an "intersection position", the position on the locus formed earlier in time is called the "first position", and the position on the locus formed later in time is called the "second position". Say.

According to the present invention, each time the locus indicated by the coordinate information group of the processing target intersects, the coordinate information of the closed figure connecting the first position on the locus to the second position on the locus overlapping with the first position is specified. At the same time, a new coordinate information group from which the specified coordinate information is excluded is set as the processing target.
Therefore, according to the present invention, when a plurality of closed figures drawn by a user by a slide operation are nested, the plurality of closed figures can be detected without omission.

In this embodiment, the effect includes at least one of the following.
(A) Visual processing for changing the display (b) Auditory processing for outputting audio (c) Internal processing for changing parameters related to the user or object

At this time, the coefficient value may be increased as the number of superposed closed regions increases.
The effect to be generated when a plurality of closed figures are formed by the sliding operation may be selected from the defined effects. For example, the selection may be made according to the relationship between the first object and the second object.

The closed figure detection procedure may be performed in real time after the slide operation is started, or may be performed after the slide operation is completed.

[Procedure 1] Coordinate information is acquired (S910).
[Procedure 2] It is determined whether or not the closed figure is completed (S920). Specifically, when the lines are arranged in the order indicated by the "next coordinate information", a line segment having two coordinates adjacent to each other at both ends is generated, and a part of the latest line segment is generated from one of the other line segments. When it overlaps a part, it is determined that the closed figure is completed. When the closed figure is completed (S920: Yes), the procedure proceeds to [Procedure 3]. At this time, the position where the closed figure is completed (or a position close to it) and the time (or a time close to this) are stored. On the other hand, when the closed figure is not completed (S920: No), the procedure proceeds to [Procedure 6].

[Procedure 3] A closed figure portion is specified (S930). Specifically, the portion included from the first position to the second position on the trajectory is regarded as the closed figure portion, and the coordinate information of the coordinates forming the closed figure is specified (FIG. 10A).
[Procedure 4] A new coordinate information group indicating a closed figure is generated (S940). Specifically, a new coordinate information group having the coordinate information of the coordinates forming the closed figure portion as a component is defined, and the coordinate related information is generated.
[Procedure 5] The coordinate information group being processed is updated (S950), and the procedure returns to [Procedure 1]. Specifically, the next coordinate information of the coordinates immediately before the first position is rewritten to the coordinates immediately after the second position. As a result, the coordinate information of the coordinates forming the closed figure is excluded from the coordinate information group being processed, and a new coordinate information group in which the coordinates immediately before the first position and the coordinates immediately after the second position are directly ordered. Is the processing target (FIG. 10B). Thereafter, [Procedure 3]-[Procedure 5] is executed every time the closed figure is completed (FIG. 10C, FIG. 10D,... ).

[Procedure 6] It is determined whether or not the next coordinate exists (S960). When the next coordinate exists (S960: Yes), the procedure returns to [Procedure 1]. On the other hand, if the next coordinate does not exist (S960: No), the process ends.

[2-7. Effect occurs]
Through the closed figure detection procedure (FIG. 9), the coordinate information group indicating the closed curve is obtained, and the coordinate information group indicating the movement path of the object to be operated remains.
The determination unit 734 of the user terminal 10 determines the content of the normal effect generated in association with the range including at least the closed curve indicated by the former (coordinate information group indicating the closed curve).

Further, when the internal areas of the two closed curves respectively indicated by any two coordinate information groups at least partially overlap, the determination unit 734 of the user terminal 10 determines that the overlapping area is present only when an object exists in the overlapping area. Determines the contents of special effects that are generated in association with. At the time of determination, it is advisable to consider the proportion of the superposed region to at least one of the two closed-curve internal regions.
The effect to be generated when a plurality of closed curves are formed by the slide operation may be one in which the content of any normal effect is modified (for example, the coefficient by which a parameter is multiplied is changed or added). For example, the value of the coefficient by which the “processing level” (FIG. 8C) is multiplied may be determined according to the number of superimpositions of the closed curve.

After the content of the effect is determined by the above, the display position of the operation target object is sequentially moved along the movement path, and the effect determined for each closed curve or overlapping area includes at least the closed curve or the overlapping area. It is generated in association with the range to be changed.

[3. Modification]
[3-1. (Modification 1) Indirect ordering]
In the embodiment, a new coordinate information group having the coordinate information of the coordinates forming the closed figure portion as a component is defined to generate the coordinate related information, and the next coordinate information of the coordinates immediately before the first position is set to the second position. By rewriting to the coordinates immediately after, the coordinates immediately before the first position and the coordinates immediately after the second position are directly ordered (S940 and S950 in FIG. 9).
On the other hand, the next coordinate information of the coordinates immediately before the first position may be rewritten to the coordinates of the intersection position, and the next coordinate information of the coordinates of the intersection position may be rewritten to the coordinates immediately after the second position. As a result, the coordinates immediately before the first position and the coordinates immediately after the second position are indirectly ordered via the coordinates of the intersection position.
At this time, the first and last coordinates of the new coordinate information group having the coordinate information of the coordinates forming the closed graphic portion as the constituent elements may be defined as the first position and the second position, respectively.

[3-2. Isolate the coordinate information of the closed figure part]
[3-2-1. (Modification 2) Order directly]
In the embodiment, the coordinate information of the closed figure portion is excluded from the coordinate information group of the processing target by rewriting the "next coordinate information" (FIG. 8E) (S940 and S950 of FIG. 9).
On the other hand, if the coordinate information has already been aligned, the "closed figure portion flag" (significant when configuring the closed figure portion) is stored in place of the "next coordinate information", and the coordinate information of the closed figure portion is stored. It is also possible to isolate from the coordinate information of the processing target.

FIG. 11 shows a modification of the closed figure detection procedure.
The user terminal 10 detects a closed figure by the following procedure.
Note that the same reference numerals are given to steps for performing the same processing as the closed figure detection procedure (FIG. 9) of the embodiment.

[Procedure 1] Coordinate information is acquired (S910).
[Procedure 2] It is determined whether or not the closed figure is completed (S1120). Specifically, a line segment whose two ends are two coordinates adjacent to each other except for a coordinate where the "closed figure part flag" is significant is generated, and a part of the latest line segment is generated from any other line segment. When it overlaps a part, it is determined that the closed figure is completed. When the closed figure is completed (S1120: Yes), the procedure proceeds to [Procedure 3]. At this time, the position where the closed figure is completed (or a position close to it) and the time (or a time close to this) are stored. On the other hand, when the closed figure is not completed (S1120: No), the procedure proceeds to [Procedure 6].

[Procedure 3] A closed figure portion is specified (S930). Specifically, the portion included from the first position to the second position on the trajectory is regarded as the closed figure portion, and the coordinate information of the coordinates forming the closed figure is specified (thick line portion in FIG. 10A). ..
[Procedure 4] A new coordinate information group indicating a closed figure is generated (S940). Specifically, a new coordinate information group having the coordinate information of the coordinates forming the closed figure portion as a component is defined, and the coordinate related information is generated.
[Procedure 5] The coordinate information group being processed is updated (S1150), and the procedure returns to [Procedure 1]. Specifically, the "closed figure portion flag" is significantly updated in the coordinate information of the coordinates forming the closed figure portion. As a result, the coordinate information of the coordinates forming the closed figure is excluded from the coordinate information group being processed (broken line portion in FIG. 10B), and the coordinates immediately before the first position and the coordinates immediately after the second position are separated. A new group of coordinate information that is directly ordered is the processing target. Thereafter, [Procedure 3]-[Procedure 5] is executed every time the closed figure is completed (thick line portion in FIG. 10C, broken line portion in FIG. 10D).

[Procedure 6] It is determined whether or not the next coordinate exists (S960). When the next coordinate exists (S960: Yes), the procedure returns to [Procedure 1]. On the other hand, if the next coordinate does not exist (S960: No), the process ends.

[3-2-2. (Modification 3) Indirect ordering]
In the second modification, a new coordinate information group having coordinate information of coordinates forming the closed figure portion as a component is defined to generate coordinate related information, and the coordinate information of the coordinates forming the closed figure portion includes “closed figure”. By significantly updating the “partial flag”, the coordinates immediately before the first position and the coordinates immediately after the second position are directly ordered (S940 and S1150 in FIG. 11).
On the other hand, the coordinate information of the intersection position may be inserted between the coordinate information of the coordinates immediately before the first position and the coordinate information of the coordinates immediately after the second position. As a result, the coordinates immediately before the first position and the coordinates immediately after the second position are indirectly ordered via the coordinates of the intersection position.
At this time, the first and last coordinates of the new coordinate information group having the coordinate information of the coordinates forming the closed graphic portion as the constituent elements may be defined as the first position and the second position, respectively.
