2. Description of the Related Art Today, in sports games,
In addition to tennis, games such as soccer, basketball, American football, and baseball have been realized.

To progress these ball game games,
With operation units (operation panel, keypad, etc.) prepared in advance for arcade machines and game-specific machines (PlayStation (manufactured by Sony Computer Entertainment Inc.), Dreamcast (manufactured by SEGA Enterprises Co., Ltd.), etc.) Operation input is required.

The operation unit is generally composed of a plurality of keys (or buttons) and a joystick. Whether it's a sports game or a role-playing game,
This means that the operation system is built with a limited number of buttons and joysticks on the operation unit. Of course, the game can be realized on a personal computer, and if a keyboard is used, keys necessary for game operation are assigned from the keys on the keyboard.

Alternatively, the player character for the ball coming in
It is possible to indirectly operate the direction and momentum of moving the ball next by operating the movement of the kuta by the player who is the user .

Consider, for example, a baseball game in which a pitcher character throws a ball toward a home base. In this case, a cursor for designating a position at which the thrown ball passes (hereinafter referred to as a ball position) is displayed inside or around the strike zone displayed on the screen. This cursor is often displayed in a shape such as a circle. A player who is a user (hereinafter, simply play
A user who operates a joystick etc.
Is a player character such as a pitcher character.
When it is clear, the word character as a pitcher is omitted.
Substantially), for example by moving a cursor on the display screen by operating the joystick, it is possible to perform the operation of specifying the ball position.

[0007]

An embodiment of the present invention will be described in detail below by using an example of a baseball game. In this embodiment,
By operating the joysticks 50e and 51e, the ball position and the hitting position can be designated. Here, the ball position is a position (displacement position) for designating a course that the ball passes through in the strike zone or in an area around the strike zone when a pitcher who is a character of the game throws the ball. The hitting position is a position (displacement position) at which the bat should pass when the batter swings the bat.

For the ball position and the hitting position, the cursor can be arbitrarily moved according to the data indicating the tilt direction and tilt angle of the joysticks 50e and 51e (hereinafter referred to as tilt data). In the present embodiment, the display position of the cursor in and around the strike zone is the ball position, and the display position of the cursor in the batting zone is the striking position. In addition, joystick 5
Data indicating tilt directions and tilt angles of 0e and 51e (tilt data) are input to the game machine body 11 via the keypads 50 and 51.

FIG. 2 is a diagram for explaining tilt data showing the state of the joystick. In FIG. 2, one joystick 50e is used for description, but the same applies to the other joystick 51e.

The joystick 50e is a device for inputting data in an analog manner and can be tilted in all directions around 360 degrees. The same applies to the joystick 51e. When the joystick 50e is tilted, the tilt direction and tilt angle are represented by two-dimensional coordinate values. In the present embodiment, with respect to FIG. 2, the tilt angle when tilted in the left-right direction is represented as a coordinate value in the x-axis direction, and the tilt angle when tilted in the up-down direction is coordinated in the y-axis direction. Expressed as a value.

The tilt angle with respect to each of the up, down, left and right directions is represented by a real value, for example. In the example of FIG. 2, the tilt angle of the joystick 50e with respect to the left is, for example, x
It is represented by a real number from 0 to 1 on the axis. The tilt angle of the joystick 50e to the right is, for example, − of the x-axis.
It is represented by a real number from 1 to 0. Joystick 50
The tilt angle of e with respect to the upper side is represented by, for example, a real number of 0 or more and 1 or less on the y axis. The tilt angle of the joystick 50e with respect to the lower side is represented by a real number of -1 or more and 0 or less on the y axis, for example. The numerical value representing the tilt angle indicates that the tilt angle is larger as the absolute value of the value is larger. Hereinafter, the numerical value representing the tilt angle in the x-axis direction is referred to as x-axis tilt data. Similarly, a numerical value indicating the tilt angle in the y-axis direction is called y-axis tilt data.

The tilt data in the x- and y-axis directions are obtained from the keypads 50 and 51, respectively.
It is acquired by converting the data according to the state of the joysticks 50e and 51e sent to the device 1. Consider a case where the tilt angles of the joysticks 50e and 51e in the x-axis direction and the y-axis direction are represented by real values of 0 to 255, and the values are input to the game machine main body 11.

The joystick 50e is located to the right in the x-axis direction.
Set the numerical value that indicates the tilt angle in the x-axis direction when the tilt is maximally tilted to “0” and move the joystick 5 to the left in the x-axis direction.
A value representing the tilt angle in the x-axis direction when 0e is tilted to the maximum is set to "255". In addition, when the joystick 50e is tilted to the maximum in the y-axis direction to the maximum, the numerical value representing the tilt angle in the y-axis direction is set to "0", and the y when the joystick 50e is tilted to the maximum in the y-axis direction, The numerical value indicating the tilt angle in the axial direction is “255”.

In such a case, if the numerical value indicating the tilt angle is an intermediate value of "255" (for example, "128"), the joystick is almost upright. "25
The difference from the intermediate value of "5" indicates the tilt angle. Then, by subtracting the intermediate value of "255" from the numerical value indicating the tilt angle and further dividing by the intermediate value of "255", it is possible to replace with the values of -1 to -1 as shown in FIG. .

Next, setting of the strike zone according to the present embodiment will be described with reference to FIG. In FIG. 3, SZ is the strike zone, G is the ground plane, C is the center position of the strike zone SZ, and A is the magnification that varies depending on the height of the player standing at bat. The strike zone SZ is a region that is displayed in a plane on the screen, as shown in FIG. As will be described later, this strike zone S
The cursor for deciding the pitching course in Z will be moved.

In the strike zone SZ, the lateral width is, for example, 43.2 cm in actual size. This width is fixed, and the size of 43.2 cm is shown as an example. In the present embodiment, the vertical width and the center position C are appropriately changed according to the height of each player. In this case, the magnification A is used. The multiplication factor A is a value obtained by dividing the height of a batter (a player standing at the bat) by a reference length (for example, 180 cm). The vertical width and the center position C, which are changed according to the batter, are obtained by multiplying the magnification A, respectively. A reference width is prepared in advance when obtaining the vertical width, and 70 cm is used as the reference width. Similarly, when the reference position C is obtained, a reference height is prepared in advance, and for example, 85 cm is used as the reference height.

Next, an example of player data according to the present embodiment will be described with reference to FIG. In FIG. 4, TBL shows a table of player data. Height 18 corresponding to each player PLY1, PLY2 ... in this table TBL
0 cm, 186 cm, etc. are registered. Other,
Athletes' abilities (shoulder strength, running strength, etc.) are also registered.

Next, the strike zone display processing according to the present embodiment will be described with reference to FIG. The program shown in FIG. 5 is recorded in, for example, the CD-ROM 19 , and is read by the control unit 12 to implement the processing.

In this strike zone display processing, first, the table TBL (see FIG. 4) is referred to and the height data of the player character standing at the bat is read (step S1). Based on this height data, the magnification A with respect to the reference length (for example, 180 cm) stored in advance is calculated. For example, in the case of the player PLY1 (see FIG. 4), the height / reference length is 180/180 and the magnification A
Is 1. Further, in the case of the player PLY2 (see FIG. 4), the height / reference length is 186/180, and the magnification A is
It becomes about 1.03.

When the magnification A is obtained, the center height Ch that determines the center position C of the strike zone SZ is then calculated (step S3). In this case, the reference height 85 cm prepared in advance is multiplied by the magnification A to obtain the center height Ch. For example, in the case of the player PLY1 (see FIG. 4), the magnification A is 1, so the center height Ch of the strike zone SZ remains the standard height of 85 cm. Further, in the case of the player PLY2 (see FIG. 4), the magnification A is approximately 1.03, so the center height Ch of the strike zone SZ is approximately 87.55 cm.

Next, the vertical width Ly of the strike zone SZ
Is calculated (step S4). In this case, the reference width 70 cm prepared in advance is multiplied by the magnification A to obtain the vertical width Ly. For example, in the case of the player PLY1 (see FIG. 4), the magnification A is 1, so the vertical width Ly of the strike zone SZ remains the reference width 70 cm.
Further, in the case of the player PLY2 (see FIG. 4), the magnification A is approximately 1.03, so the vertical width L of the strike zone SZ is L.
y is approximately 72.1 cm.

In this way, with respect to the strike zone SZ, when the center height Ch, the vertical width Ly, and the fixed horizontal width Lx are aligned, the positional relationship to be arranged in the screen is determined using these data (steps). S5). That is,
In the case of player PLY1 (see FIG. 4), the center height is 85
cm (Ch), height 70 cm (Ly), and width 4
Arrangement on the screen is determined by 3.2 cm (Lx). In the case of player PLY2 (see FIG. 4), the center height is 87.55 cm (Ch), the vertical width is 72.1 cm (Ly),
Then, the arrangement within the screen is determined by the width of 43.2 cm (Lx).

When the position where the strike zone SZ is arranged on the screen is determined, the strike zone SZ is displayed on the screen (step S6).

In the baseball game of this embodiment, the position of the cursor at the time of pitching or hitting is controlled in accordance with the tilt data of the joystick. 6, the shape of the present state
The strike zone by a diagram schematically showing. Figure 6
61 indicates a strike zone. As shown in FIG. 6, in the present embodiment, the strike zone 61 is set on a plane parallel to the XY plane in the three-dimensional space.

In FIG. 6, the coordinates of the reference position O of the strike zone 61 are (X0, Y0). It is the position of the strike zone 61 in the plane including the strike zone 61. The strike zone 61 is displayed on the screen as, for example, a rectangular frame having the reference position O as the center position. In the example of FIG. 6, the range of the strike zone 61 in the X-axis direction is a range of X4 or more and X3 or less. The range of the strike zone 61 in the Y-axis direction is a range of Y4 or more and Y3 or less.

At the position P1 inside the strike zone 61 or around the strike zone 61, a cursor 62 used for pitching is displayed. Cursor 6
2 is displayed in a circle, for example. The position of the cursor 62 is a position indicating a reference for moving the cursor 62. The cursor 62 can move within the strike zone 61 and a range 64 around the strike zone 61. As an example, X
Axis value is X2 or more and X1 or less, and Y axis value is Y2 or more and Y
The range of 1 or less is the movable range of the cursor 62.

The movable range 64 of the cursor 62 is set wider than the strike zone 61 because the player may intentionally throw the ball in a course other than the strike zone 61. If the pitch is thrown on a course other than the strike zone 61, the probability that the batter hits the hit is very low. Therefore, pitching to a course other than the strike zone 61 is an effective means for advancing the competition.

At a position P3 inside the strike zone 61, a cursor (hereinafter, referred to as a hitting cursor) 63 used at the time of hitting is displayed. For example, the batting cursor 63 is displayed in a circle. The position of the batting cursor 63 is a reference position for moving the batting cursor 63. The batting cursor 63 can move within the strike zone 61. In the example of FIG. 6, the value on the X axis is X4 or more and X3.
The range in which the Y-axis value is Y4 or more and Y3 or less is the movable range of the batting cursor 63.

In this embodiment, the joystick 50 is used.
The movement target position of the cursor 62 is determined according to the state of e, and the cursor 62 is moved toward the movement target position. The movement target position is represented by the displacement of the strike zone 61 from the reference position O. In the example of FIG. 6, the cursor 62
This is a state in which the position P1 and the movement target position match. Hereinafter, the distance from the reference position O of the strike zone 61 to the movement target position, the position of the cursor 62, and the batting cursor in the X-axis direction is called the X-axis displacement, and the Y-axis distance is the Y-axis displacement. Will be called.

As shown in FIG. 6, the displacement of the movement target position in the X-axis direction is a function Fh having a variable tilt data (x) indicating the tilt angle of the joystick 50e in the x-axis direction.
Defined by (x). Also, the displacement of the movement target position in the Y-axis direction is a function Fv having a variable tilt data (y) indicating the tilt angle of the joystick 50e in the y-axis direction.
Defined by (y).

The displacement of the position of the batting cursor 63 in the X-axis direction is defined by a function Gh (x) having a tilt data (x) indicating the tilt angle of the joystick in the x-axis direction as a variable. The displacement of the batting cursor 63 in the Y-axis direction is
It is defined by a function Gv (y) having a tilt data (y) indicating the tilt angle of the joystick in the y-axis direction as a variable.

FIGS. 7A, 7B and 7C schematically show an example of changes in the movement target position according to the state transition of the joystick 50e. Note that FIG.
(A), (B) and (C) show the joystick 50.
In this example, e is tilted in the positive direction of the x axis. Figure 7
(A) shows the state change of the joystick 50e, (B) shows the tilt data in the x-axis direction according to the state of the joystick 50e, (C) of the same figure.
Indicates the value of the function F h (x) obtained according to the tilt data.

The joystick 50e is shown in FIG.
The tilted state of is shown. Seven states S as an example
T0, ST1, ST2, ST3, ST4, ST5, ST
6 is shown. State ST0 is joystick 5
0e shows the state where it is not tilted. With reference to this state ST0, from state ST1 to state ST2, state ST3,
The tilt angle in the positive direction of the x-axis increases in the order of state ST4, state ST5, and state ST6. The state ST6 is a state in which the x-axis is tilted to the maximum in the positive direction.

The above seven states ST0, ST1, ST2,
The tilt data of ST3, ST4, ST5 and ST6 are "0", "1/6", "2/6", "3/6",
These are “4/6”, “5/6”, and “1” (see FIG. 7B). That is, the values of the tilt data of the seven states of the joystick increase by 1/6 each time the state changes from the state ST0.

Tilt data "0", "1/6", "2 /"
6 ”,“ 3/6 ”,“ 4/6 ”,“ 5/6 ”, and“ 1 ”, the displacement of the movement target position is Fh (0),
Fh (1/6), Fh (2/6), Fh (3/6), F
h (4/6), Fh (5/6), and Fh (1) (see FIG. 7C). The value of Fh (0) is 0. The value of Fh (1) is | X1-X0 | (the absolute value of the difference between X1 and X0).

As shown in FIG. 7C, the larger the tilt angle of the joystick 50e, the smaller the change amount of the movement target position corresponding to the change amount of the tilt angle of the joystick 50e. That is, the value of the function Fh (x) indicating the displacement of the movement target position in the X-axis direction has the following relationship.

[Expression 1] {Fh (1/6) -Fh (0)}> {Fh (2/6)-
Fh (1/6)}> {Fh (3/6) -Fh (2 /
6)}> {Fh (4/6) -Fh (3/6)}> {Fh

(5/6)}

As described above, the larger the tilt angle of the joystick 50e, the smaller the change amount of the moving target position corresponding to the change of the tilt angle of the joystick 50e. The moving speed becomes slower and fine adjustment becomes easier. Figure 6
As shown in FIG. 7, when the tilt angle of the joystick 50e increases, the displacement of the movement target position of the cursor 62 increases, and the area near the strike zone 61 approaches. That is, fine adjustment of the movement target position in the area around the strike zone 61 becomes easy.

FIG. 8 shows an example of the function Fh (x). In FIG. 8, the horizontal axis shows the absolute value (| x |) of the tilt data, and the vertical axis shows the value of the function Fh (x). The curve L1 shown in FIG. 8 is a sine using sine.
It is a curve. As shown in FIG. 8, in the function Fh (x) represented by the curve L1, the value of the function Fh (x) increases as the absolute value of the tilt data increases. Further, the larger the absolute value of the tilt data, the smaller the slope of the tangent line of the curve L1. The smaller the slope of the tangent to the curve L1, the smaller the change in the value of the function Fh (x) with respect to the change in the absolute value of the tilt data.

The function Fh (x) can be expressed, for example, by the following equation. [Formula 2] Fh (x) = | X1−X0 | × sin (| x × (π /
2) |)

Here, x is tilt data in the x-axis direction, and π is the pi. X1 is the X-axis maximum value of the movable region of the cursor, X0 is the X-axis coordinate value of the reference position of the movable region (Strike zone over emissions of the reference position O and the same).

If the tilt data in the x-axis direction is a positive value,
X-axis coordinate value X0 of the reference position O of the movable area of the cursor
By adding the value of Fh (x) to, the X-axis coordinate value of the movement target position is obtained. If the tilt data in the x-axis direction is a negative value, the value of Fh (x) is subtracted from the X-axis coordinate value X0 of the reference position O in the movable area of the cursor,
The X-axis coordinate value of the movement target position is obtained.

Similarly, the displacement of the target movement position in the Y-axis direction from the reference position can be calculated. For example,
The function Fv (y) is represented by the following formula. [Formula 3] Fv (y) = | Y1-Y0 | × sin (| y × (π /
2) |)

Here, y is tilt data in the y-axis direction. Y1 is the maximum Y-axis value of the movable area of the cursor, and Y0 is the Y-axis coordinate value of the reference position O of the movable area. If the tilt data has a positive value, the Y-axis coordinate value of the movement target position can be obtained by adding the value of Fv (y) to the Y-axis coordinate value Y0 of the reference position O of the movable area. If the tilt data is a negative value, the reference position O of the movable area is
The Y-axis coordinate value of the movement target position can be obtained by subtracting the value of Fv (y) from the Y-axis coordinate value Y0 of.

When the movement target position according to the state of the joystick 50e is obtained, the position of the cursor is moved so as to approach the movement target position. The transition of the cursor position is shown in FIGS. 9 (A), (B), (C), and (D).
Will be explained. 9 (A), (B), (C), and (D) are diagrams schematically showing the moving state of the cursor.

In FIG. 9A, the position of the cursor 62 is
It is the reference position O within the movable range 64. When the joystick 50e is tilted to specify the ball position in such a state, as shown in FIG.
The movement target position P2 is determined according to the state of the joystick. Then, the cursor 62 moves toward the movement target position at the preset speed V. The speed V is
For example, it is the amount of movement of the cursor 62 per frame.

After that, the cursor 62 is displayed as shown in FIG.
As shown in (D), for example, the position P1 is set for each frame.
2. The position P13 is gradually approached to the movement target position P2. When the cursor 62 can reach the movement target position P2, the cursor 62 is moved to the same position as the movement target position P2.

As described above, in the present embodiment, the cursor 62 is controlled so as to follow the movement target position.
Therefore, the cursor 62 can always be moved smoothly.

Further, when the distance between the movement target position P2 and the position of the cursor 62 becomes less than or equal to a preset distance, the cursor 62 can be prevented from approaching the movement target position P2. This is a measure for preventing the position of the cursor 62 from moving.

That is, when the player operates the joystick with his / her finger, it is difficult to fix the tilt angle at a constant angle. That is, even if the player intends to keep a certain angle, the tilt angle of the joystick actually changes. Therefore, if the cursor 62 is always made to accurately follow the movement target position, the position of the cursor 62 on the display screen changes sequentially (for example, for each frame), and the image becomes difficult to see.

Therefore, the movement target position P2 and the cursor 62
When the distance between the positions is less than the preset distance, the position P1 of the cursor 62 is prevented from approaching the movement target position P2 to control the cursor display so as not to follow the camera shake. Is possible.

Next, the movement control of the batting cursor according to the joystick will be described. In general, the attacking player cannot know in advance which course the ball will be thrown until the ball is thrown. Therefore, the attacking player waits for the ball with the batting cursor displayed near the center of the strike zone.

When the ball is thrown, the player predicts the arrival position of the ball within the strike zone or its periphery from the trajectory of the ball. In order to hit the ball, it is necessary to move the batting cursor to the predicted position before the ball reaches the strike zone or its periphery.

If the batting cursor is displayed near the center of the strike zone and waiting for the ball, the amount of movement of the batting cursor can be small when the ball reaches the vicinity of the center of the strike zone. Thus, in the vicinity of the center of the strike zone, by performing the fine adjustment of the position of the batting cursor, it is desirable to be striking the ball accurately. Therefore, in the present embodiment, contrary to the movement control of the cursor at the time of pitching, display control of the batting cursor is performed so that the position of the batting cursor can be finely adjusted near the center of the strike zone.

The position of the batting cursor can be calculated by a function having the value of the tilt data of the joystick as a variable. For example, the position of the batting cursor (displacement in the X-axis direction from the reference position O of the strike zone) can be obtained using the function Gh (x) in which the data of the tilt data in the x-axis direction is used as a variable. Similarly, the position of the batting cursor (displacement in the Y-axis direction from the reference position O of the strike zone) can be obtained by the function Gh (y) using the data of the tilt data in the y-axis direction as a variable.

FIG. 10 shows an example of the function Gh (x). In FIG. 10, the horizontal axis shows the absolute value of the tilt data in the x-axis direction, and the vertical axis shows the value of the function Gh (x). The curve L2 shown in FIG. 10 is a sine curve. As shown in the figure, the function G represented by the curve L2
Regarding h (x), the larger the absolute value of the tilt data, the larger the value of the function Gh (x). Further, the larger the absolute value of the tilt data, the larger the slope of the tangent line of the curve L2. The smaller the slope of the tangent to the curve L2, the smaller the change in the value of the function Gh (x) with respect to the change in the absolute value of the tilt data, that is, the slower the moving speed.

As described above, by setting the curve L2 such that the inclination of the tangent line of the curve L2 becomes smaller as the absolute value of the tilt data is closer to 0, the position of the batting cursor can be slightly adjusted when the joystick is almost upright. Adjustment becomes easy. When the joystick is nearly upright, the value of the function Gh (x) is also small, so the batting cursor is near the center of the strike zone. Therefore, by using the function Gh (x) represented by the curve L2, it becomes easy to finely adjust the batting cursor near the center of the strike zone.

The function Gh (x) can be expressed by the following equation, for example. [Formula 4] Gh (x) = | X3-X0 | × {sin (| x | × (π
/ 2) -π / 2) +1}

Here, x is tilt data in the x-axis direction. X3 is the maximum X-axis value of the movable area of the batting cursor, and X0 is the movable area (strike zone 6
It is the X-axis coordinate value of the reference position O in 1). If the tilt data is a positive value, the X-axis coordinate value of the batting cursor is obtained by adding the value of Gh (x) to the X-axis coordinate value X0 of the reference position O of the strike zone. If the tilt data has a negative value, the X-axis coordinate value of the batting cursor is obtained by subtracting the value of Gh (x) from the X-axis coordinate value X0 of the reference position O of the strike zone.

Similarly, the displacement of the batting cursor in the Y-axis direction from the center position of the strike zone can be calculated. For example, the function Gv (y) is represented by the following formula. [Formula 5] Gv (y) = | Y3-Y0 | × {sin (| y | × (π
/ 2) -π / 2) +1} Here, y is tilt data in the y-axis direction. Y3 is
Y0 is the maximum value of the movable area of the batting cursor, and Y0
Is the Y-axis coordinate value of the reference position O of the movable area (strike zone 61). If the tilt data is a positive value,
In the Y-axis coordinate value Y0 of the reference position O of the strike zone, G
By adding the value of v (y), the Y-axis coordinate value of the position of the batting cursor can be obtained. If the tilt data has a negative value, the Y-axis coordinate value of the position of the batting cursor is obtained by subtracting the value of Gv (y) from the Y-axis coordinate value Y0 of the reference position O of the strike zone.

It is also possible to correct the position of the batting cursor so that the position of the batting cursor approaches the arrival position of the ball around the strike zone 61. Figure 11
(A), (B) is a figure explaining the position correction of a batting cursor.

In FIG. 11 (A), the strike zone 61
A batting cursor 63 is displayed at a position P31 in the inside. Here, when the ball is thrown, the arrival position P4 of the ball is calculated. Arrival position P4, the position and the cursor 6 3 determined in accordance with the operation input or the like of the defensive player, pitch type (straight, curved, chute or the like) is determined by calculation of a computer in accordance with the. For example,
The position of the cursor 6 3 is used to determine the movement direction immediately after the ball 81 is thrown. In addition, ball type is ball 8
Used to calculate the orbit of 1.

Further, the position P corresponding to the state of the joystick is calculated by the calculation using the functions Gh (x) and Gv (y).
32 is determined. Then, the correction position P33 for bringing the position P32 closer to the arrival position P4 of the ball is determined. The corrected position P33 is, for example, a position on a line segment connecting the position P32 and the reaching position P4. And the same figure (B)
As shown in, the batting cursor 63 is moved to the position P33.

According to the present embodiment, the position of the batting cursor is corrected when the distance between the arrival position of the ball and the position of the batting cursor determined according to the state of the joystick becomes a predetermined distance or less. Shall be implemented only in The predetermined distance is, for example, the distance (| Y1-Y0 |) from the center position of the strike zone 61 to the maximum value of the strike zone 61 in the Y-axis direction.

Further, the correction amount α (α is a real number) for correcting the position of the batting cursor can be obtained by the following equation, for example. [Equation 6] α = {1-D / (| Y1-Y0 |)} U where D is the position of the batting cursor (value before correction, which is determined according to the arrival position of the ball and the state of the joystick). ) Is a real number that indicates the distance. U is a real number preset to indicate the degree of correction. The larger the value of U, the larger the correction amount per frame. In the present embodiment, the correction is not performed when the correction amount α has a negative value.

Moreover, only when the position of the batting cursor (value before correction) determined according to the state of the joystick is updated so as to approach the arrival position of the ball,
The position of the batting cursor may be corrected. That is, the position of the batting cursor is corrected only when the player operates the joystick so as to bring the batting cursor closer to the arrival position of the ball.

In this, the distance between the arrival position of the ball and the position of the batting cursor (value before correction) in the immediately previous frame is stored. Then, the stored distance is compared with the distance between the arrival position of the ball in the current frame and the position of the batting cursor (position before correction). If the distance between the arrival position of the ball and the position of the batting cursor (position before correction) in the current frame is smaller, it is determined that the batting cursor is operated to approach the reaching position of the ball.

Next, the relationship between the state transition and the operation according to this embodiment will be described. 12, FIG. 13, and FIG. 14 are diagrams showing an example of the state transition of the image at the time of pitching according to the present embodiment. In the following state transition example, it is assumed that the defending player is operating the keypad 50 and the attacking player is operating the keypad 51. The player who operates the player character on the defensive side can perform an operation input indicating an instruction to start a pitching motion. For example, the buttons 50a, 50b, 50c, 5 of the keypad 50
Any of 0d is associated with the instruction to start the pitching operation. Then, when the player presses the button associated with the instruction to start the pitching operation, the pitcher's pitching motion is displayed on the screen.

First, FIG. 12 shows an example of a display screen after the pitcher starts the pitching motion. In FIG. 12, three characters, a pitcher 71, a batter 72, and a catcher 73, are displayed on the display screen 101. On the screen, catcher 73
Is displayed semi-transparently. The strike zone 61 is displayed on the back side of the catcher 73. Further, in the strike zone 61, a cursor 62 for designating the ball position and a batting cursor 63 for indicating the position of the bat swing are displayed. Further, in the state of FIG. 12, the pitcher 71 holds the ball 81.

Further, the cursor 62 can be moved within the strike zone 61 and around the strike zone 61 by the operation of the joystick 50e by the player. For example, when the player tilts the joystick 50e downward, the cursor 62 moves to the display screen 1
Move below 01. Player has joystick 5
When 0e is tilted upward, the cursor 62 moves above the display screen 101. When the player tilts the joystick 50e to the right, the cursor 62 moves to the right of the display screen 101. When the player tilts the joystick 50e to the left, the cursor 62 moves to the left of the display screen 101.

The cursor 62 is the joystick 50e.
Is moved to a position determined according to the state (tilt angle and tilt direction) of. Specifically, joystick 5
The tilting angle of 0e and the tilting direction determine the movement target position within the plane including the strike zone 61. The cursor 62 moves at a constant speed toward the movement target position.

When the pitching motion of the pitcher 71 is started, the image of the catcher 73, which has been displayed opaque, is displayed semitransparently. When the image of the catcher 73 becomes translucent, the transparency gradually increases from the opaque state. In addition, FIG.
In the example, the cursor 62 is moved to the lower left in the strike zone 61. The cursor 62 can be moved by operating the joystick 50e until the ball 81 moves away from the pitcher's hand.

The batting cursor 63 can be moved within the strike zone 61 by the attacking player operating the joystick 51e of the keypad 51. The player on the attacking side predicts the course in which the actual ball is thrown from the position of the cursor 62, and moves the batting cursor 63 toward the course. For example, when the player tilts the joystick 51e downward, the batting cursor 63 moves downward on the display screen 101. When the player tilts the joystick 51e upward, the batting cursor 63 moves upward in the display screen 101. When the player tilts the joystick 51e to the right, the batting cursor 63 moves to the right of the display screen 101. When the player tilts the joystick 51e to the left, the batting cursor 63 moves to the left on the display screen 101.

When the motion of the pitcher progresses and the ball 81 moves away from the pitcher's hand, the cursor 62 (shown in FIG. 12) for designating the ball position is erased from the display screen 101 as shown in FIG. After the cursor 62 disappears from the screen, the attacking player moves the ball 8
Predict the trajectory of the ball 81 by the position of 1
Batting cursor 63 at the position where 1 is expected to be thrown
Can be moved. In the example of FIG. 13, the batting cursor 63 is moved to the lower left of the strike zone 61.

The cursor 62 for designating the ball position continues even after the ball 81 has left the pitcher's hand.
May be displayed. If the cursor 62 is continuously displayed, the attacking player can move the batting cursor 63 with the position of the cursor 62 as a target. This makes it easier for the attacking player to hit the ball 81.

When the ball 81 reaches the periphery of the strike zone 61, as shown in FIG.
(Shown in FIG. 13) is deleted from the display screen 101. Further, by the operation input using the keypad 51 by the attacking of the player, when the instruction of the batting is performed, the motion of the swing of the batter 72 is displayed. The swing motion is such that the bat held by the batter 72 passes through the position designated by the batting cursor 63.

As described above, the defensive player can move the cursor 62 to throw the ball 81 at a position where the batter 72 has difficulty hitting. In a general baseball game, the area near the center of the strike zone is set to be easy to hit, and the area near the boundary between the strike zone and its periphery is set to be hard to hit. That is, by throwing the ball 81 in the vicinity of the strike zone 61, the possibility of hitting the batter increases.

In the present embodiment, the strike zone 61
The position of the cursor 62 can be finely adjusted in the vicinity of the boundary around the and. Therefore, the player on the defensive side can accurately throw the ball on a course that is difficult for the batter to hit. On the other hand, the attacking player can finely adjust the position of the batting cursor near the center of the strike zone 61. Therefore, when the ball is thrown near the center of the strike zone 61, the ball 81 can be accurately hit back.

Next, the operation of the pitching process according to this embodiment will be described. FIG. 15 is a flowchart illustrating the pitching process according to the embodiment of the present invention. This flowchart shows the processing when the player character on the defensive side is operated by the player. Further, this flowchart is a process from the state where the pitcher holds the ball.

First, when the pitching process is started, the strike zone display process is executed (step S10). This strike zone display processing has already been described with reference to FIG. 5, and will be omitted here.

It is determined whether or not there is an operation input for starting a pitch (step S11). The operation input for starting a pitch is performed by operating a button on a keypad or a joystick for determining the type of ball (straight, curved, shoot, etc.). If there is no operation input to start the pitch (step S11: NO route), the process of step S11 is repeated until the operation input to start the pitch is received.

When it is determined in step S11 that there is an operation input for starting a pitch (step S11: YES route), the state of the joystick operated by the defense player is detected (step S12). The state of the joystick is the tilt angle and tilt direction of the joystick. For example, the state of the joystick is represented by tilt data (-1 to +1) in the x-axis direction and tilt data (-1 to +1) in the y-axis direction.

The cursor movement target position is calculated according to the state of the joystick (step S13). The movement target position is calculated for each frame by a calculation based on a function having tilt data as a variable.

Next, the distance between the position of the cursor currently displayed and the movement target position calculated in step S13 is calculated, and it is determined whether or not the distance is within a predetermined distance (step S14). . Whether or not the distance between the cursor and the movement target position is within a predetermined distance is determined for each display frame. When it is determined that the distance between the cursor and the movement target position is within a predetermined distance (step S14:
YES route), without the processing in step S15, the process proceeds to step S16.

When it is determined that the distance between the cursor and the movement target position is not less than the predetermined distance (step S14:
(NO route), the cursor is moved at a predetermined speed so as to approach the movement target position, and the cursor is displayed at the moved position (step S15).

Then, it is judged whether or not the ball is thrown (step S16). Whether or not the ball has been thrown can be determined, for example, by detecting that the pitching motion of the pitcher has reached the position where the ball is released. If the ball has not been thrown (step S1)
6: NO route), the process proceeds to step S12. As a result, the cursor movement control is repeated according to the joystick state until the ball is thrown.
Done .

When the ball is thrown (step S1)
On the 6: YES route), the movement of the ball toward the cursor is started (step S17). In the present embodiment, the moving direction of the ball when it is separated from the pitcher's hand is the direction designated by the position of the cursor,
When a changing sphere is specified, the ball moves on the curved trajectory. Therefore, the ball does not always pass the position of the cursor. When the ball is hit by the batter or caught by the catcher, the movement process of the ball in the pitching process ends. As a result, the pitching process is also completed.

As described above, by determining the moving target position according to the state of the joystick and gradually moving the cursor designating the ball position to the moving target position, it is possible to smoothly control the movement of the cursor.

Next, the operation of the hitting process according to this embodiment will be described. FIG. 16 is a flowchart illustrating the hitting process according to the embodiment of the present invention. The hitting process is a process started from the time when the pitching motion of the pitcher is started.

First, the state of the joystick operated by the attacking player is detected (step S21). The state of the joystick is the tilt angle and tilt direction of the joystick. The joystick state is x
It is represented by tilt data (-1 to +1) in the axial direction and tilt data (-1 to +1) in the y-axis direction.

The position of the batting cursor is calculated according to the state of the joystick (step S22). The position of the batting cursor can be calculated by an operation based on a function having tilt data as a variable.

It is determined whether or not the distance between the passing position of the ball and the position of the batting cursor calculated in step S22 is within a predetermined distance and is closer than the position of the immediately preceding batting cursor (step). S23). If the distance between the passing position of the ball and the position of the batting cursor is not within a predetermined distance, or if it is not closer than the position of the immediately preceding batting cursor (step S23: NO route).
In step S25, the process proceeds to step S25.

When the distance between the passing position of the ball and the position of the batting cursor is within a predetermined distance and is closer than the position of the immediately preceding batting cursor (step S23: Y).
The position of the batting cursor is corrected to the (ES route) (step S24). For example, the position of the batting cursor is corrected so that the position of the batting cursor approaches the passing position of the ball. In this case, the closer the distance between the ball passing position and the batting cursor position is, the greater the correction amount of the batting cursor position can be.

Then, the batting cursor moved to the position calculated in step S22 or the position corrected in step S24 is displayed on the screen (step S2).
5). Then, it is determined whether or not the operation input of the batting instruction is performed by the keypad operated by the attacking side (step S26). When the operation input of the batting instruction is not performed (step S26: NO route), it is determined whether or not the ball has passed the strike zone or its periphery (step S27). For example, when the ball crosses a plane including the strike zone, it can be determined that the ball has passed the strike zone or its periphery.

When the ball passes through the strike zone or its periphery (step S27: YES route), the batting process ends. If the ball has not passed the strike zone or its surroundings (step S2
7: NO route), the process proceeds to step S21, and the batting cursor movement display process is continuously performed.

If it is determined that there is a batting instruction operation input (step S26: YES route), batting processing is performed toward the position of the batting cursor (step S28). For example, the batter's motion such that the batter's bat passes the position of the batting cursor is displayed on the screen. Then, the hitting process ends.

As described above, in the present embodiment,
The moving speed of the cursor near the boundary between the strike zone and its surroundings was made smaller than the moving speed in other areas. This facilitates fine adjustment of the ball position near the boundary between the strike zone and its surroundings.

In the present embodiment, the moving speed of the batting cursor near the center position of the strike zone is
It is smaller than the moving speed in other areas. This facilitates fine adjustment of the hitting position near the center of the strike zone.

Further, in the present embodiment, the ball position is calculated using the function for designating the ball position, and the hitting position is calculated using a function different from that function. Therefore, for the ball position, a function that allows easy fine adjustment near the boundary between the strike zone and its periphery is used, and for the hitting position, a function that allows easy fine adjustment near the center of the strike zone is used. Can be used. Accordingly, each player, with good operability, respectively, it is possible to perform position specification using the joystick.

In the present embodiment, an example of displaying an image from the viewpoint behind the catcher has been described, but it is also possible to display an image from the viewpoint behind the pitcher. 17 and 18 show examples of display screens from the viewpoint behind the pitcher.

The display image of FIG. 17 shows an example of the display image when the scene shown in FIG. 12 is drawn from the viewpoint behind the pitcher. As shown in FIG. 17, when the screen is displayed from the viewpoint behind the pitcher 71, the batter 72, the catcher 73, and the referee 74.
Can be displayed from the front. By displaying the image on the screen from the viewpoint behind the pitcher, the strike zone 6
1, the cursor 62 and the batting cursor 63 are catchers 73
It is displayed in front of the referee 74. This improves the visibility when the player operates the joystick to move the cursor 62 or the batting cursor 63.

The display screen of FIG. 17 displays the strike zone 61 from the opposite direction of the display screen of FIG. Therefore, for example, when the defensive player tilts the joystick to the left, in the example of FIG. 12, the cursor moves in a direction away from the batter 72, but FIG.
In the example, the cursor moves in a direction approaching from the batter 72.

When the ball 81 moves away from the pitcher's hand from the state shown in FIG. 17, the cursor 62 is removed from the display target as shown in FIG. It should be noted that until the ball 81 passes around the strike zone 61, the attacking player can move the attack cursor 63 using the joystick to specify the hitting position.

In this way, by displaying the image from the viewpoint behind the pitcher, the visibility of the strike zone 61, the cursor 62, and the batting cursor 63 is improved, and the player can easily operate.

Images from a plurality of viewpoints can be displayed on the screen at the same time. FIG. 19 is a diagram showing a display example in which an image from the viewpoint behind the batter and an image from the viewpoint behind the pitcher are simultaneously displayed on the screen. In FIG. 19, an image from the viewpoint behind the batter is displayed on the left side of the display screen 101. An image from the viewpoint behind the pitcher is displayed on the right side of the display screen 101.

In the image from the viewpoint behind the batter, pitcher 7
1a, batter 72a, catcher 73a, strike zone 61
a, a cursor 62a, a batting cursor 63a, and a ball 81a are displayed. The catcher 73a in the image from the viewpoint behind the batter is displayed semi-transparently. In the image from the viewpoint of the pitcher direction, the pitcher 71b and the batter 72
b, catcher 73b, referee 74b, strike zone 61
b, a cursor 62b, a batting cursor 63b, and a ball 81b are displayed.

By simultaneously displaying images from a plurality of viewpoints in this way, even when two players are competing, the viewpoints from the rear of the player (pitcher or batter) operated by each player Now you can play the game. As a result, the image can be viewed from the viewpoint that each player can easily operate, and the operability of the game is improved.

That is, since the cursor position is moved on the two-dimensional plane by the function processing based on the sine in the X-axis direction and the Y-axis direction, the delicate cursor movement is realized according to the tilt of the operating body. be able to. This makes it possible to improve the accuracy and operability of the cursor display position when moving the cursor in each of the strike zone and the batting zone.

As described above, the ball position with respect to the determined ball can be manipulated near the boundary between the strike zone and the outside of the zone. That is, it is possible to finely adjust the ball position, and it is possible to realize a delicate operation to a desired ball position.

On the other hand, in the batting zone, it is more common for the batter to swing toward the center of the zone than to swing near the boundary between the zone and the outside of the zone. For the player, it is preferable that the batting position can be finely adjusted at the center of the batting zone. Therefore, according to the above-described embodiment, it is possible to finely adjust the striking position, and it is possible to realize a delicate operation to a desired striking position.

In the above-described embodiment, with respect to the cursor operation in the strike zone, the moving process is calculated by throwing and hitting, but the present invention is not limited to this, and the plane is calculated by using a constant. You may make it calculate the cursor position to move. Two modifications will be described below.

First, the first modification will be described with reference to the flowchart of FIG. In this first modification, an example in which the tilt data of the joystick is converted into coordinate data by using a constant that is common to both the X-axis and the Y-axis for cursor movement. Here, only the pitching process will be described. First, a strike zone display process is performed (step 31). This strike zone display process is performed in the same manner as in FIG. 5 described above, and a description thereof will be omitted.

Next, the state of the joystick is detected (step S32), and the cursor movement target position is obtained as coordinate data (step S33). In step S33, as described above, only the constants common to the X axis and the Y axis are used to convert the tilt data of the joystick into the coordinate data.

When the cursor movement target position is determined, the cursor movement is display-controlled toward the coordinate position (step S34). In this case, step S31
Since the strike zone is set in, the cursor movement range is within the strike zone. That is, when the cursor reaches the outer circumference, the cursor serves as a limiter, and further outward movement is restricted.

Next, a second modification will be described with reference to the flowchart of FIG. In this second modified example, regarding the cursor movement, an example in which the tilt data of the joystick is converted into coordinate data by using different constants for the X axis and the Y axis is shown. Here again, only the pitching process will be described. First, a strike zone display process is performed (step 41). This strike zone display process is performed in the same manner as in FIG. 5 described above, and a description thereof will be omitted.

Next, the joystick state is detected (step S42), and the cursor movement target position is obtained as coordinate data (step S43). In this step S43, as described above, the tilt data of the joystick is converted into coordinate data by using different constants for the X axis and the Y axis, so that the aspect ratio of the strike zone obtained in step S41 is required. In step S41, since the height is calculated, the aspect ratio with the fixed width is calculated. By using this aspect ratio, for example, when the strike zone is vertically long, the number of coordinates in the vertical direction, that is, the Y-axis direction is larger than that in the X-axis direction.

When the cursor movement target position is determined, the cursor movement is display-controlled toward the coordinate position (step S44). In this case, step S41
Since the strike zone is set in, the cursor movement range is within the strike zone. That is, when the cursor reaches the outer circumference, the cursor serves as a limiter, and further outward movement is restricted.
