The following technical limitations may be added to the "information processing device" according to one aspect of the present invention. Further, similar technical limitations may be added to the "control method" and "control program" according to one aspect of the present invention.
For example, a technical limitation may be added in that the determining means determines the amount of change of a parameter that defines an effect to be generated in association with the formed closed figure.
The following technical limitations may be further added to the "information processing device" to which the above technical limitations have been added. Further, similar technical limitations may be further added to the "control method" and "control program" to which the technical limitations are added.
For example, the reference element is an element related to the position of the end point of the trajectory, the comparison element is an element related to the position of the completed point of the closed figure, and the specifying means is an element related to the position of the end point of the trajectory, A technical limitation may be added in which the degree of separation of the comparison elements is specified as the relative relationship. Here, when the reference element is the start position of the series of touch operations, the determining means determines that the larger the separation, the larger the change amount, or the smaller the separation, the larger the change amount. It is preferable to determine the amount of change in the parameter so that the parameter becomes large. On the other hand, when the reference element is the end position of the series of touch operations, the determining means may be configured such that the smaller the separation, the larger the change amount, or the larger the separation, the larger the change amount. The trick is to determine the amount of change in the parameter so that it increases.

Here, when the reference element is the start time of the series of touch operations, the determining means determines that the larger the separation, the larger the change amount, or the smaller the separation, the larger the change amount. It is preferable to determine the amount of change in the parameter so that the parameter becomes large. On the other hand, when the reference element is the end time of the series of touch operations, the determining means may be configured such that the smaller the separation, the larger the change amount, or the larger the separation, the larger the change amount. It is preferable to determine the amount of change in the parameter so that the parameter becomes larger.
The following technical limitations may be added to the "information processing device" according to one aspect of the present invention. Further, similar technical limitations may be added to the "control method" and "control program" according to one aspect of the present invention.
For example, the reference element is the maximum length set for the length from the starting point to the ending point of the trajectory, the comparison element is the length from the starting point of the trajectory to the completion point of the closed figure, A technical limitation may be further added in that the determining means determines an amount of change of a parameter defining an effect of extending the maximum length. At this time, the specifying means specifies the degree of separation between the reference element and the comparison element as the relative relationship each time the closed figure is formed, and the determining means determines that the smaller the degree of separation, the more the amount of change. It is preferable to determine the amount of change in the parameter so that the amount of change becomes larger, or the amount of change becomes larger as the degree of separation becomes larger.

In the present invention, the reference element related to the reference point on the trajectory of a series of touch operations and the comparison element related to the completion point of the closed figure formed by the trajectory, depending on the relative relationship between the reference element and the comparison element related to the completion point of the closed figure formed by the trajectory Decide what changes to the effect should occur.
Therefore, if the content of the effect is changed in accordance with the change content determined by the present invention, in an electronic game in which an effect is generated in association with a closed figure drawn by a trajectory of a series of touch operations on a touch panel, the completion point of the closed figure can be improved. Changes are added to the electronic game according to the changes.

[Step 2] Store the contact position data (S720). At this time, the time at which the contact position was acquired is further stored.
[Step 3] It is determined whether the slide operation has ended (S730). If the slide operation is not completed (S730: No), the process returns to [Step 1]. When the slide operation is completed (S730: Yes), the process advances to [Step 4]. At this time, the start time and end time of the slide operation are stored.

Subsequently, the user terminal 10 changes at least one type of parameter when the trajectory of the slide operation forms a closed figure.
[Step 4] It is determined whether a closed figure has been drawn (S740). If a closed figure is not drawn (S740: No), the process ends. If a closed figure is drawn (S740: Yes), the process advances to [Step 5]. At this time, the position (or approximate position) and time (or approximate time) of the completed closed figure are stored.
[Step 5] The relative relationship between the reference element and the comparison element is specified (S750). For example, the distance between the start position and the completed position (A1), the distance between the end position and the completed position (A2), the distance between the start time and the completion time (B1), the distance between the end time and the completion time Identify at least one of (B2).

[Step 6] Select the parameters to be changed (S760). For example, it is preferable to select parameters related to one object surrounded by a closed figure formed by the slide operation. Further, for example, parameters may be selected depending on a combination of an object to be operated (first object) and one object (second object) surrounded by a closed figure formed by the slide operation. In this embodiment, it is assumed that the "processing level" of the effect setting information (FIG. 6(c)) is selected.
[Step 7] The amount of change in the parameter selected in [Step 6] is determined (S770). For example, the larger the degree of separation (A1, B1) specified in [Step 5], the larger the amount of change, or the smaller the degree of separation (A2, B2), the greater the amount of change.
[Step 8] The parameters selected in [Step 6] are changed by the amount of change determined in [Step 7] (S780).

[3. Modified example]
[3-1. Parameters to be changed]
In the above embodiment, the user terminal 10 is configured to change the "processing level" in the effect setting information (FIG. 6(c)) when a closed figure is completed (see [2-6. Parameter change procedure described above). ]). Since an effect includes at least one of visual processing, auditory processing, and internal processing (see [1-1. Overview] above), if the "processing level" related to the effect is changed, the level of the effect (for example, attack・The magnitude of recovery, etc., and the breadth and narrowness of the area of influence) will change.
On the other hand, the configuration may be such that at least one of the "visual processing code", "auditory processing code", and "internal processing code" in the effect setting information (FIG. 6(c)) is changed. Further, the configuration may be such that a different effect is executed by changing the "effect ID" to be referred to.

On the other hand, the success or failure of the closed figure may be determined in real time during the slide operation. If the configuration is such that the success/failure determination of the closed shape is executed in real time, the effect can be generated during the slide operation (for example, immediately after the closed shape is completed).

[3-3. Effects when determining the success or failure of closed shapes in real time]
If the configuration is such that the success or failure of a closed shape is determined during the slide operation (the above modified example [3-2. Timing for determining the success or failure of a closed shape]), even if the effect is generated when the closed shape is completed, good. Furthermore, a plurality of effects with different properties may be generated both when the closed figure is completed and when the slide operation is completed.
For example, on the premise that an upper limit value for the length of the trajectory is set, an effect that includes internal processing to increase the upper limit value is set, and the degree to which the upper limit value is increased is determined based on the relative relationship between the reference element and the comparison element. can be configured to be determined according to the Specifically, it is preferable to change the "processing level" (FIG. 6(c)) of the effect that increases the "slide operation residual value" (FIG. 6(a)).
Note that the effect that includes internal processing to increase the upper limit of the length of the trajectory is configured to be activated only when a specific object (for example, an item that increases the upper limit) exists in the internal area of the closed shape. You may.
