The predicted position storage table 112 is a table that stores predicted positions of characters. FIG. 3 is a diagram showing an example of the predicted position storage table 112 according to one embodiment. The predicted position storage table 112 stores the reception time when the user operation is received and the predicted position of the character at predetermined time intervals from the reception time.

The prediction unit 14 predicts the action of the character according to the user's operation in the game. The determination unit 15 refers to the action prediction condition table 111 and determines whether the predicted action is a specific action and has an operating condition for the action. When the determining unit 15 determines that the motion condition of the predicted action is defined, the predicting unit 14 determines the predicted position of the character from the current time until the elapse of a predetermined time according to the determined specific motion condition. . In the example of the action prediction condition table 111 shown in FIG. 3, the prediction unit 14 stores predicted character positions at intervals of 1/30 second until two seconds have passed since the reception time. However, the predicted position of the character after a predetermined time has elapsed from the current time is not limited to the predicted position until two seconds after the reception time, and may be less than one second or longer than one second. Also, the time interval for predicting the position of the character is not limited to 1/30 seconds, but may be 1/60 seconds or other time intervals.

Communication I/F 27 is an interface that connects information processing apparatus 10 to a network. Communication I/F 27 communicates with other devices via a communication unit having an antenna.

The input I/F 28 is an interface that connects to an input device such as the controller 1 . The controller 1 has operation buttons 2 and direction keys 3 .

[Position prediction processing]
Next, an example of position prediction processing according to one embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of position prediction processing according to one embodiment. When this process is started, the reception unit 13 receives a user operation using the controller 1, and the prediction unit 14 predicts the action of the character based on the received user operation (S10). Next, the reception unit 13 sets 1 to the variable n (S12).

Next, the prediction unit 14 predicts the action of the character after n/30 seconds based on the action predicted immediately before (S14). Here, the action of the character after 1/30 second from the reception time of the user operation is predicted.

Next, the prediction unit 14 predicts the position of the character after n/30 seconds based on the action predicted this time (S16). Here, the position of the character after 1/30th of a second is predicted. At this time, the determination unit 15 refers to the action prediction condition table 111 and determines whether or not the operation conditions for the action predicted according to the user's operation are defined. When it is determined that the operating condition of the action predicted according to the user's operation is defined, the prediction unit 14 predicts the position of the character according to the defined operating condition of the action.

For example, FIG. 6 shows an example of a game scene in which an enemy character Ba and a player character operated by a user (hereinafter referred to as "character Bb") are drawn. The character Bb can move while flying in the air or between buildings using a wire whose one end is fixed to the upper part of the object Oj. In the example of FIG. 6, the character Bb moves to the upper right along the trajectory F in response to the operation to move the controller 1 to the right.

The action using the wire of such a character (hereinafter referred to as "wire action") is not a simple uniform linear motion or free fall motion, but a special action corresponding to the expansion and contraction of the wire. It is possible to give the user an exhilarating feeling of moving to another area, thereby enhancing the interest of the game. On the other hand, the wire action cannot predict the position of the character by simple calculation, unlike uniform linear motion. Therefore, in the present embodiment, the action prediction condition table 111 is referred to, and the position of the character is predicted according to action conditions defined according to a specific action such as a wire action. As a result, it is possible to accurately predict the movement position of the character according to the user's operation for a specific action.

Returning to FIG. 5, when the prediction unit 14 predicts in S14 that the action is due to the "stretch wire" operation, in S16 the action prediction condition table 111 is referred to, and the action defined for the predicted "stretch wire" action is performed. Identify conditions. Then, the prediction unit 14 calculates the expansion/contraction of the wire and the moving direction of the character according to the operating direction of the wire, based on the operating conditions of the action. Thereby, the prediction unit 14 predicts the position of the character Bb after 1/30 second. .

Also, for example, it is assumed that the prediction unit 14 determines that the wire has been extended until it is cut by a certain action, based on the action prediction condition table 111 that defines information such as how long the wire must be extended before it is cut. In this case, in S14, the prediction unit 14 predicts the previous action of the character, that is, the action when the wire is cut, as the action of the character, and 1/1 based on the predicted action of the character when the wire is cut. Predict the position of the character after 30 seconds.

As a result, as an example is shown in FIG. 7, for the predicted wire action, the position (x ₁ , y ₁ ) of the character Bb after 1/30 second from the current position (x ₀ , y ₀ ) of the character Bb is changed to Returning to FIG. 5, next, the prediction unit 14 stores the predicted position (x ₁ , y ₁ ) of the character Bb after 1/30 second in the predicted position storage table 112 in association with the reception time (S18). ). In the example of FIG. 3, the reception time "○○ hour △△ minutes XX seconds" at which the user operation was received and the position (x ₁ , y ₁ ) of the character Bb 1/30 second after the reception time are stored. .

Returning to FIG. 5, next, the prediction unit 14 adds 1 to the variable n (S20) and determines whether the variable n is greater than 60 (S22). When it is determined that the variable n is 60 or less, the process returns to S14, and the prediction unit 14 predicts the action of the character after n/30 seconds based on the action predicted immediately before (S14). In the example of FIG. 7, based on the action of the character Bb at the position (x ₁ , y ₁ ), the action of the character 2/30 seconds after the reception time, that is, 1/30 seconds after the previous action is predicted. . A position to be predicted is stored in the predicted position storage table 112 . In the example of FIG. 3, the predicted position storage table 112 stores the reception time "○○ hour △△ minute XX second" and the position (x ₁ , y ₁ ) of the character Bb after 1/30 second. The position (x ₂ , y ₂ ) of the subsequent character Bb is stored.

Returning to FIG. 5, the prediction unit 14 adds 1 to the variable n (S20), and repeats the processes of S14 to S22 while the variable n is determined to be 60 or less (S22). As a result, as shown in FIG. 7, character positions (x ₁ , y ₁ ) to (x ₆ , y ₆ ), . 112.

If it is determined in S22 that the variable n is greater than 60, the process ends. As a result, as shown in FIG. 7, after the user operation is received, the position to which the character will move is predicted at predetermined time intervals (1/30 second in this embodiment) from the immediately preceding action. 2 seconds in this embodiment) is repeated. As a result, as shown in FIG. 3, 60 character positions are stored in the predicted position storage table 112 at intervals of 1/30 second until two seconds after the reception time.

Note that the number of repetitions in S22 is not limited to 60, and can be set variably. It is preferable to set the number of repetitions in consideration of the balance between the accuracy of the predicted position and the processing load.

[Attack processing]
An example of attack processing executed using the character positions predicted in the position prediction processing described above, that is, the character positions stored in the predicted position storage table 112 will be described with reference to FIG. FIG. 8 is a flowchart illustrating an example of attack processing according to one embodiment.

When this process is started, the accepting unit 13 accepts a user operation using the controller 1 (S30), the game execution unit 12 executes the game program, and after a predetermined time has elapsed from the time when the user operation was accepted, It is determined whether or not to attack (S32). When the game execution unit 12 determines that the attack will not be performed after the predetermined time has passed since the reception time, the process ends. On the other hand, when the game execution unit 12 determines that the attack will be performed after the predetermined time has passed since the reception time, it determines whether the predetermined time has passed (S34). When determining that the predetermined time has elapsed, the game executing unit 12 specifies the character's predicted position after the predetermined time from the reception time, among the character's predicted positions stored in the predicted position storage table 112, and moves toward the predicted position. to attack (S36). After attacking, this process ends.

9, in S36 of FIG. 8, the game execution unit 12 specifies the predicted position (x ₅ , y ₅ ) of the character 5/60 seconds after the reception time of the user operation, and from the enemy character Ba, the predicted position An attacking image is displayed at (x ₅ , y ₅ ).

When another character or the like attacks a character that moves with a specific action, it takes an arbitrary amount of time before the attack is actually applied. For example, an action such as catching an enemy or hitting an enemy may take from one second to several seconds or longer. On the other hand, as described above, according to the present embodiment, even in the case of a specific action such as a wire action in which the position of the character cannot be predicted by simple calculation, the operating condition of the specific action is Predict the position of the character according to As a result, it is possible to accurately predict the position of a character performing a specific action one to several seconds later, and to attack the predicted position. As a result, it is possible to prevent the character Bb from being attacked at a position different from the position at which the character Bb is present, and draw a natural action.

In this embodiment, the wire action is used as an example to describe the method of predicting the position of the character according to the operating conditions of a specific action, but the present invention is not limited to this. For example, in the action prediction condition table 111, action conditions for character actions are defined according to the injection amount of gas injected from a gas injector worn by the character. Therefore, the position of the character may be predicted according to the operating conditions, with the action of injecting gas as a specific action. The position of the character may be predicted according to each operating condition corresponding to the combination of the action of injecting gas and the wire action, or the combination of other specific actions. This also makes it possible to accurately predict the movement position of the character according to the user's operation for a combination of specific actions. As a result, it is possible to accurately perform an attack or the like on a character performing a specific action, and it is possible to render one scene of the game more naturally.

The information processing device, the position prediction method, and the position prediction program according to one embodiment disclosed this time should be considered as examples and not restrictive in all respects. The embodiments described above can be modified and improved in various ways without departing from the scope and spirit of the appended claims. The items described in the above multiple embodiments can take other configurations within a consistent range, and can be combined within a consistent range.

For example, the predicted position storage table 112 stores predicted positions of characters at intervals of 1/30 second. Therefore, for example, the position of the character for time intervals finer than 1/30 second may be calculated using predicted positions immediately before and after that time. For example, when calculating the position of the character at an intermediate time between 1/30 second and 2/30 second after the reception time, (x ₁ , y ₁ ) indicating the position after 1/30 second and 2/30 By calculating the average value of (x ₂ , y ₂ ) indicating the position after seconds, the predicted position of the character can be complemented.
