[Game processing example]
Next, an outline of an example of processing of the game system according to the embodiment of the present invention will be described based on an example of a baseball game as shown in FIGS. 5 and 6A to 6D. FIG. 5 is a flowchart showing the operation of the game system according to the embodiment of the present invention. This flowchart mainly assumes a scene in which the ball 610 is thrown by the pitcher character 603. In this embodiment, it is assumed that the batting action of the batter character 602 is controlled by the game system.

  When the user instructs execution of the baseball game from among the executable games displayed on the main menu screen (not shown), the baseball game is started (S101), and as shown in FIG. The initial screen including the catcher character 601, batter character 602, pitcher character 603, strike zone 604, etc. is displayed (S102). In FIG. 6A, a course designation cursor 605 for designating a pitching course (ball arrival target) is displayed at the center of the strike zone 604. In addition, a spherical type display 606 indicating a correspondence relationship between the swipe direction and a spherical type such as a straight line or a curve is radially provided from the course designation cursor 605. The strike zone 604 and the course designation cursor 605 are translucently displayed so as not to block the display of the catcher character 601 and the like. Note that the ball type display 606 can be made to depend on the ability of the pitcher character 603 so that a specific ball type, for example, a folk ball or the like, is not displayed according to the ability of the pitcher character.

  In FIGS. 6A to 6D, an image obtained by shooting the stadium with a virtual camera from behind the pitcher character 603 is displayed as a background image. Note that the viewpoint of the virtual camera can be changed to a viewpoint from a long distance or an overhead viewpoint so that the situation can be confirmed in a wide range.

  Next, it is determined whether or not the pitching operation is started by touching an arbitrary position on the operation surface (S103). If the determination result is right, as shown in FIG. 6B, the display indicating the correspondence between the swipe direction and the ball type is deleted, and the operation index 607 is displayed at a position corresponding to the touch position on the screen. . In addition, a circle 608 surrounding the strike zone 604 is displayed. In this state, the movement of the course designation cursor 605 by the operation index 607 is allowed (S104). If the determination result is not, the process returns to step S102.

  When the operation indicator 607 is operated by a swipe operation on the operation surface in a state where the movement of the course specifying cursor 605 is permitted, the course specifying cursor 605 moves in conjunction with the operation indicator. The movement of the course designation cursor 605 is allowed only for a predetermined period from the timing of touching the operation surface, that is, the timing of starting the pitching operation, and the movement of the cursor 605 is prohibited when the predetermined period elapses. . Therefore, the timing operation is started from the timing of the pitching operation, and it is determined whether or not a predetermined period has elapsed (S105). The predetermined period may be associated with the pitching motion, and the period until the pitching motion reaches the predetermined motion mode may be set as the predetermined period. In this way, operability adapted to the pitching motion can be realized.

  In the above determination, if it is determined that the predetermined period has elapsed, the movement of the course designation cursor 605 by the operation index 607 is prohibited (S106). If it is determined that the predetermined period has not elapsed, the process returns to step S104.

  In a state where the movement of the course designation cursor 605 is prohibited, the ball type or the like is designated by swiping the operation surface (S107). For example, the sphere type is specified by the swipe direction. Details of the touch information acquisition method by the swipe operation and the relationship between the swipe operation and the specification of the sphere type will be described later.

  If it is determined in step S106 that the predetermined period has elapsed, timing is started simultaneously with the prohibition of the movement of the course designation cursor 605, and the size of the circle 608 surrounding the strike zone 604 decreases accordingly. I will do it. Then, the timing at which the size of the circle 608 is minimized coincides with the timing at which the pitcher character 603 releases the ball 610.

  In this aspect, the arrival position accuracy (throwing accuracy) of the ball is improved as the timing of the swipe operation approaches the release timing of the ball. Therefore, if the user visually recognizes the size of the circle 608 and performs a swipe operation at a timing when the size is minimized, the arrival position accuracy (throwing accuracy) can be maximized. In this way, the ball arrival position accuracy (throwing accuracy) is set based on the timing of the swipe operation (S108). An example of a technique for controlling the accuracy of reaching the ball with respect to the target will be described later.

  It should be noted that it is not always necessary to set the pitching accuracy as a continuous amount, and the pitching accuracy can be set stepwise as necessary. Further, when the pitching accuracy, the ball type, or the like is not specified at the time of ball release due to a delay in the swipe operation, control based on a predetermined specific value may be performed.

  Next, determination of the flight parameter of the ball and calculation / display of the flight path of the ball are performed (S109). FIG. 6D shows an example of the game screen after the ball is released.

  As will be described later, in order to accurately determine the trajectory of the ball flying in the three-dimensional virtual space after the release, the velocity vector, the rotation axis, and the rotation amount of the ball immediately after the release may be given as initial conditions of the ball flight. . Since the velocity vector can be grasped as a three-dimensional amount, the rotation axis, and the rotation amount as a one-dimensional amount, if the five parameters are designated as the initial conditions of the ball flight, the flight trajectory of the ball is determined.

  On the other hand, the goal (throwing course) of the ball specified by the user can be grasped as a two-dimensional quantity and corresponds to two parameters. Therefore, by swiping to specify the ball type, etc., the remaining three parameters are set. You may make it specify. An example of a technique for this will be described later.

  Hereinafter, a touch information acquisition method, a control method of the accuracy of reaching the ball with respect to the target, the principle of calculating the ball flight path, and a method for causing the ball to reach the vicinity of the target position will be described.

[Touch Information Acquisition Method]
A method for acquiring touch information by a swipe operation will be described.
When the user performs a touch operation on the screen, the contact of an object with the touch screen is detected, and the start point position of the touch operation corresponding to the operation start position is designated. Then, the touch position on the touch screen is detected and stored at a predetermined cycle (for example, a frame rate of 30 fbps).

  In this manner, information on the touch position is sequentially acquired, and the touch moving direction and touch are determined from the touch position (vector; two-dimensional coordinate position) of the previous frame and the touch position (vector; two-dimensional coordinate position) of the current frame. The distance between them can be calculated, and the speed of the touch operation is calculated by dividing the calculated distance by the frame rate.

[Method of controlling the accuracy of the ball reaching the target]
In one embodiment, as the swipe operation is performed at a timing closer to the release timing of the ball, the accuracy of reaching the ball with respect to the target is improved. An example of a control method for this will be described below.

For example, consider a concentric circle whose radius decreases with a decrease in the time until the ball release timing, and randomly select a point P in the inner region of the concentric circle at the time of the swipe operation, and use the center of the concentric circle as the origin Let the coordinates of this randomly selected point P be (p _x , p _y ). Coordinates _(t x, _{t y)} of the guide position of the original goals, this coordinates _(p x, _{p y)} coordinates obtained by adding _{(t x + p x, t} y + p y) if the set as a position to be reached Good.

  When the above method is adopted, when the swipe operation is performed at a timing that takes a long time to release the ball, the point P in the inner region of the concentric circle is randomly selected with the radius of the concentric circle being relatively large. For this reason, there may be a case where a point greatly deviating from the initial target target position is set as the target target position. In addition, when the swipe operation is performed at a timing close to the ball release timing, the point P in the inner region of the concentric circle is selected at random with the radius of the concentric circle being relatively small. A case where a point greatly deviating from the reference position is set as the target position cannot occur. Therefore, as the swipe operation is performed at a timing closer to the release timing of the ball, the accuracy of reaching the ball with respect to the reaching target is improved.

[Principle explanation of ball flight path calculation]
In order to determine the trajectory of the ball flying in the three-dimensional virtual space, the velocity vector, the rotation axis, and the rotation amount of the ball immediately after the release may be given as the initial conditions of the ball flight. An example of the principle of flight path calculation (three-dimensional flight trajectory calculation) is roughly as follows.

As the external force (vector) acting on the ball, there are a drag D, a lift L, a torque T, and gravity, but the magnitude of the drag D | D |, the magnitude of the lift L | L |, and the magnitude of the torque T The magnitude | T | is expressed as follows using a drag coefficient C _D , a lift coefficient C _L , and a fluid torque coefficient C _m , which are aerodynamic coefficients.
| D | = 0.5ρ | U | ² A * C _D (Formula 1)
| L | = 0.5ρ | U | ² A * C _L (Formula 2)
| T | = 0.5ρ | U | ² Ad * C _m (Formula 3)
Where ρ: air density, | U |: magnitude of the flying speed of the ball, A: ball diameter cross-sectional area, and d: ball diameter.

Here, the aerodynamic parameters of the drag coefficient C _D , the lift coefficient C _L , and the fluid torque coefficient C _m can be approximately expressed as a function of the rotational speed and flying speed of the ball. The rotational speed gradually decreases due to the fluid torque. However, if necessary, the reduction of the rotational speed N (t) may be considered based on the following model formula (Formula 11).
N (t + Δt) = − ρAdC _m (t) | U | ² Δt / (4πI) + N (t) (Formula 4)
Where C _m (t) is the fluid torque coefficient at time t, and I is the moment of inertia of the ball.

Drag (vector) D, it is the velocity (vector) U opposite direction of the ball, lift (vector) L is considering that such orthogonal speed of the ball and (vector) U to the rotation axis Z _R, The equation of motion (differential equation) of the ball during flight can be easily derived. If the initial velocity (vector) of the ball, the direction of the axis of rotation, and the amount of rotation are given as initial conditions, numerical calculation of the flight trajectory of the ball ( For example, it can be determined by the Euler method).

[Method to make the ball reach near the target position]
As described above, if the velocity vector (initial velocity vector), rotation axis, and rotation amount of the ball immediately after release are given as initial conditions, the flight trajectory of the ball can be determined by three-dimensional flight trajectory calculation.

  In the case of pitching, the goal of the ball is given in advance, and the release position of the ball and the plane distance from the ball release position to the goal of arrival are substantially constant. The condition will be set. An example of a method for causing the ball to reach the vicinity of the reaching target position is roughly as follows.

First, assuming that the motion of the ball is the motion of a mass point that approximately moves in the earth's gravitational field, if the initial velocity vector V ₀ (three-dimensional vector) is specified, the flight trajectory of the ball is determined under the above assumption. Is done. Therefore, given the position information (two-dimensional coordinates: (t _x , t _y )) of the target and the magnitude of the initial velocity vector V ₀ | V ₀ | = v ₀ , the initial velocity vector is assumed under the above-mentioned assumptions. V ₀ is determined as a function V ₀ (t _x , t _y , v ₀ ) of the target position information (t _x , t _y ) and the magnitude v ₀ of the initial velocity vector V ₀ .

Next, the handling in the case where the motion of the ball is the motion of a rigid body moving in the earth gravity field will be described. As noted above, the position information of the goals, assuming a ball and mass (t _{x, t y)} and the initial velocity vector V _{0 (t} which is determined as a function of the size v ₀ of the initial velocity vector V _{0 x} , t _y , v ₀ ) will be referred to as “tentatively determined initial velocity vector”. Then, the flight trajectory of the ball is determined by giving the provisionally determined initial velocity vector V ₀ (t _x , t _y , v ₀ ), the rotation axis φ, and the rotation amount N as initial conditions. Is out of reach with the contribution of the rotation axis φ of the ball and the rotation amount N. Therefore, it is necessary to correct the tentatively determined initial velocity vector V ₀ (t _x , t _y , v ₀ ) so that the flight trajectory passes the reaching target.

For this purpose, for example, it may be possible to perform a simulation of ball flight by correcting the provisionally determined initial velocity vector V ₀ (t _x , t _y , v ₀ ) little by little. Given the limitations, this approach is expected to be difficult. Therefore, in order to achieve the goal by taking into account the contributions of the rotation axis φ and the rotation amount N, the initial velocity vector (hereinafter, “the temporary velocity vector V ₀ (t _x , t _y , v ₀ )) is corrected. A corrected initial velocity vector V ₀ ′ (t _x , t _y , v ₀ ) ”is obtained in advance, and a five-dimensional table (hereinafter, referred to as five parameters t _x , t _y , v ₀ , φ, N) The corrected initial velocity vector V ₀ ′ (t _x , t _y , v ₀ ) corresponding to the area specified by each address of the “correction table” may be stored.

In preparing the correction table in advance, for example, the provisional decision initial velocity vector V ₀ (t _x , t _y , v ₀ ) is corrected little by little in consideration of the contributions of the rotation axis φ and the rotation amount N. And adopt the provisionally determined initial velocity vector V ₀ (t _x , t _y , v ₀ ) that realizes the attainment target as the corrected initial velocity vector V ₀ ′ (t _x , t _y , v ₀ ), It may be stored in the correction table. Note that the simulation of the ball flight may be performed based on, for example, the “principal description of ball flight path calculation” described above.

In order to obtain the rotation axis φ, the rotation amount N, and the magnitude v ₀ of the initial velocity vector V ₀ by the swipe operation, for example, the rotation axis φ is specified by the direction of the swipe operation, and the rotation amount N is determined by the distance of the swipe operation. And the magnitude v ₀ of the initial velocity vector V ₀ may be specified according to the speed of the swipe operation. It is also possible to adopt a simple method of acquiring the information s of the ball type using only the direction of the swipe operation and acquiring the information of the rotation axis φ and the rotation amount N as a function of the information s of the ball type. . In this latter case, the correction table can be configured as a four-dimensional table addressed with (t _x , t _y , v ₀ , s). Alternatively, when a predetermined relationship is defined between the rotation axis φ and the rotation amount N, the correction table is configured as a four-dimensional table addressed by (t _x , t _y , v ₀ , φ). it can.

In particular, in the former case, (t _x , t _y , v ₀ , φ, N) used for addressing the five-dimensional correction table does not match the discretely set correction table address. Is also envisaged. In such a case, for example, a plurality of addresses in a correction table close to a five-dimensional point defined by (t _x , t _y , v ₀ , φ, N) are selected and stored in the plurality of addresses. Read V ₀ ′ (t _x , t _y , v ₀ ), combine them appropriately, add them with a predetermined weight (perform so-called interpolation), and approximately correspond to the corrected initial velocity vector V ₀ ′ (t _x , t _y , v ₀ ) can be acquired.

In the above description, in order to simplify the description, a five-dimensional point (t _x , t _y , v ₀ , φ, N) or the like is used for direct addressing. However, t _x , t Obtained by applying one-to-one mappings f ₁ , f ₂ , f ₃ , f ₄ , and f ₅ to _{y 1} , v ₀ , φ, and N, respectively (f ₁ (t _x ), f ₂ (t _y )). , F ₃ (v ₀ ), f ₄ (φ), f ₅ (N)) may be employed as addresses. In this way, the addresses can be ordered as addresses (j, k, l, m, n) consisting of integers. To restore (t _x , t _y , v ₀ , φ, N) from this address (j, k, l, m, n), map f ₁ , j, k, l, m, n _{f 2, f 3, f 4} , inverse mapping _f ¹ -1 of ^{_{f 5, f 2 -1, f}} 3 -1, f 4 -1, the ^{f 5 -1} may be applied, respectively.
