FIG. 2 is a block diagram showing a functional configuration of the terminal 100 according to the first embodiment of the present invention. The terminal 100 includes a processing unit 200 including an application progression unit 210 and a display processing unit 230. The application progression unit 210 further includes a touch input detection unit 212, a ball type determination unit 214, a landing reference area determination unit 216, and an object motion control unit 218. The processing unit 200 may further include a communication control unit (not shown).

The terminal 100 according to the present embodiment executes a tennis game by a game program. The terminal 100 displays on the display 114 a tennis court, a player character 302, a battle character 304, and a ball (an example of an object, not shown) as shown in FIG. In addition, as will be described later, one of the player character 302 and the battle character 304 is controlled according to a command input from the player, and the tennis game is advanced by hitting the ball with each other.

FIG. 3 shows the game space 300 displayed on the display 114 of the terminal 100. The game space 300 includes a three-dimensional game space that includes an XY plane. The game space 300 includes a player character 302 that is operated by the player, and a self-place 310 and an opponent place 312 that are arranged so as to sandwich the net along the Y-axis direction. The own base 310 and the opponent base 312 include the XY plane. A service line, a center service line, a base line, and a side line are set in the own base 310 and the opponent base 312, respectively. In the game space 300, the player character 302 plays a tennis game with the battle character 304 on such a tennis court.

The opponent base 312 has a plurality of landing reference areas 308 on which the balls hit by the character 302 land. The player can hit the spot where the ball hits the opponent base 312 by designating one of the landing reference areas 1as to 6as by an operation described later. Each of the landing reference areas 308 includes a landing reference point 306. After any of the landing reference points 1s to 6s is designated by the operation of the player, an appropriate error is further calculated to thereby calculate the landing reference areas 1as to 6as. The landing position of the ball is determined.

In FIG. 3, each of the landing reference areas 308 is a circle having a radius that fits within a predetermined section set in an area 314 surrounded by a side line, a net, and a center service line. The landing reference area 308 is virtually arranged on the opponent base 312 and may or may not be displayed on the game screen 300. FIG. 3 shows an example of the landing reference area 308 when the player character 302 serves the opponent character 304. When the character 302 serves from the right court of the own team, the service line on the opponent base 312 is shown. Landing reference areas 1as to 6as are set in the area between the center service line and the left side of the center service line. When the character 302 serves from the left court of his team, the landing reference areas 1'as to 6'as are located between the service line on the opponent's base 312 and the net and on the right side of the center service line. Is set.

Next, with reference to FIG. 2 and FIG. 4, the operation of each functional unit executed by the processing unit 200 by the game program in the present embodiment will be described. The processing unit 200 functions as an application progression unit 210 and a display control unit 230. The application progression unit 210 functions as a touch input detection unit 212, a ball type determination unit 214, a landing reference area determination unit 216, and an object motion control unit 218.

First, the application progression unit 210 determines a game scene in progress, and selects a ball type candidate that can be selected by the player according to the determined game scene (step S1). For example, in a scene where the player character hits a serve, a candidate for the ball type related to the serve (spin, flat) is selected. In a scene where a hit ball from the opponent character (an opponent hit ball) is returned, a candidate for the type of ball related to the return ( Spin / Rob). The display processing unit 230 displays the selected ball type candidate on the display 114 (step S1).

Then, the touch input detection unit 212 detects a touch input for the selectable ball type candidates displayed on the display 114 (step S2).
Next, the ball type determination unit 214 determines the serve ball type or the return ball type selected by the player based on the touch input detected in step S2. The display processing unit 230 displays the ball type selected by the player on the display 114 (step S3).

FIG. 5 shows a case where the serve ball type selected by the player is a top spin. FIG. 6 shows a case where the serve ball type selected by the player is a flat serve. In each game space 300, ball type candidates that can be selected by the player are displayed on the ball type switching button 504. In FIG. 5 and FIG. 6, the top spin and the flat serve can be switched for the ball type by the player's operation on the ball type switching button 504. In this embodiment, when a touch operation (for example, a tap) is input to the ball type switching button 504 arranged at a predetermined position on the touch panel 102 by the player, the ball type determination unit 214 specifies the ball type at the time of hitting.

7 and 8 show a ball type switching button 702 that indicates a plurality of return ball type candidates selected by the player. In FIG. 7 and FIG. 8, two types of “spin / lob” are shown as the ball type candidates.

Next, the touch input detection unit 212 detects the touch direction with respect to the touch end position from the touch start position of the touch input (step S4). The touch input detection unit 212 can detect the coordinate position on the touch panel where the tap operation by the player is input and the touch input (slide / swipe operation) detected continuously. Of the successively detected touch positions, the first detected position is referred to as a touch start position, and the last detected position is referred to as a touch end position. The touch input detection unit 212 can specify the touch direction of the touch input that is continuously detected based mainly on the touch start position and the touch end position. Further, the touch input detection unit 212 can detect the distance of the touch operation and the time required from the touch start to the touch end. The touch start position may be a point set in advance in the operation input unit (touch panel) 102 or may be an arbitrary position.

Next, the landing reference area determination unit 216, based on the ball type selected in Step S3 and the touch direction detected in Step S4, a plurality of points defined on the opponent base 312 in the game space. One of the landing reference areas 308 is designated (step S5).
For example, as shown in FIG. 5, based on the trajectory of the touch operation 502 of the player, the touch input detection unit 212 detects the touch start position (point A) and the touch end position, and specifies the touch directions 1ts to 6ts. The landing reference area determination unit 216 specifies landing reference areas 1as to 6as corresponding to the specified touch directions 1ts to 6ts.

In this embodiment, first, landing reference points 1s to 6s corresponding to the touch directions 1ts to 6ts are designated. For example, when a touch operation from the touch start position (A) to the upper left and left of the screen is detected, the corresponding touch direction 1ts is specified, and the corresponding landing reference point 1s is specified. Further, an actual landing point (not shown) in the landing reference area 1as is determined by adding a predetermined deviation to the landing reference point 1s by various methods as will be described later. Thereby, the landing reference areas 1as to 6as corresponding to the touch directions 1ts to 6ts can be designated. The player can enjoy various play styles by relatively simple operations.

In the present embodiment, when the ball type is specified, the landing reference area 308 (landing reference point 306) associated with the touch direction changes. That is, the landing reference area 308 is specified based on the ball type and the touch direction. When the flat serve is specified as shown in FIG. 6, when the touch operation includes a displacement in the X-axis direction, the landing reference areas 1as to 3as on the opponent base 312 according to the displacement. Is specified. For example, when a touch direction and a touch operation distance reaching the negative area area1 on the X axis from the touch start position (A) are detected, the landing reference area 1as is designated. When a touch direction and a touch operation distance that reach the positive area area3 on the X axis from the touch start position (A) are detected, the landing reference area 3as is designated. If neither the negative area area1 nor the positive area area3 has been reached from the touch start position (A), the landing reference area 2as is designated.

7 and FIG. 8, the ball type and the landing reference area 308 are specified based on the touch direction. As shown in FIG. 7, when the touch direction includes a displacement in the positive direction with respect to the Y axis, or when the touch direction includes almost no displacement in the Y axis direction, the ball type “spin” is selected according to the displacement. ”Is designated, and any one of the landing reference areas 1a to 6a on the opponent side value 312 is designated. For example, when the touch direction and the touch operation distance reaching the area area1 that is positive in the Y-axis direction and negative in the X-axis direction from the touch start position (A) are detected, the landing reference area 1a is designated. . When the touch direction and the touch operation distance reaching the area area2 that is positive in the Y-axis direction and substantially free of displacement in the X-axis direction from the touch start position (A) are detected, the landing reference area 2a is designated. . In addition, when a touch direction and a touch operation distance that reach the positive area area3 that is positive in the Y-axis direction and positive in the X-axis direction from the touch start position (A) are detected, the landing reference area 3a is designated. . Further, when the touch direction and the touch operation distance reaching the negative area area4 in the X-axis direction with almost no displacement in the Y-axis direction from the touch start position (A) are detected, the landing reference area 4a is designated. Is done. Further, when the touch direction and the touch operation distance reaching the positive area area 6 in the X-axis direction with almost no displacement in the Y-axis direction from the touch start position (A) are detected, the landing reference area 6a is designated. Is done. Further, when the touch operation distance from the touch start position (A) is less than a certain value, the landing reference area 5a is designated.

In addition, as shown in FIG. 8, when the touch direction includes a displacement in the negative direction with respect to the Y-axis, the ball type “Rob” is designated according to the displacement, and the opponent team value 312 is displayed. Any one of the landing reference areas 1a to 3a is designated. For example, when a touch direction and a touch operation distance that reach the negative area area1 in both the Y-axis direction and the X-axis direction from the touch start position (A) are detected, the landing reference area 1a is designated. When the touch direction and the touch operation distance reaching the area area2 that is negative in the Y-axis direction and almost not displaced in the X-axis direction from the touch start position (A) are detected, the landing reference area 2a is designated. . In addition, when a touch direction and a touch operation distance that reach the area area 3 that is negative in the Y-axis direction and positive in the X-axis direction from the touch start position (A) are detected, the landing reference area 3a is designated. .

Next, the object motion control unit 218 calculates the trajectory of the ball hit by the character 302 so as to land at an arbitrary position within the landing reference reference area designated in step S4 (step S6). The object motion control unit 218 designates an arbitrary position in the landing reference area 308 as an actual landing point. Further, the object motion control unit 218 causes the player character 302 to perform an action of hitting the ball (return action, serve action) according to the ball type selected in step S3 (step S6).

Next, the display processing unit 230 displays the player character controlled by the object motion control unit 218, the ball moving along the calculated trajectory, and the like on the display 114 (step S7). Based on information from the object motion control unit 218, the display processing unit 230 outputs to the display 114 an image signal for moving and displaying the player character and the battle character on the court in the virtual space. The display processing unit 230 also outputs to the display 114 an image signal for moving and displaying a ball moving along the calculated trajectory on the court in the virtual space based on information from the object motion control unit 218.
Second Embodiment
In the present embodiment, the position where the ball lands is changed from the landing reference point based on information regarding touch input made on the touch panel and information regarding the ball located in the game space. The game is complicatedly developed by simply detecting a simple operation (touch input).

FIG. 9 is a block diagram showing a functional configuration of the terminal 100 according to the second embodiment of the present invention. The terminal 100 can include a processing unit 200 including an application progression unit 210 and a display processing unit 230. The application progression unit 210 further includes a touch input detection unit 212, a landing reference region determination unit 216, an object motion control unit 218, a landing region size determination unit 220, a swing field determination unit 222, a timing determination unit 224, an offset / landing point determination unit. 226 and a hitting speed determination unit 228 can be provided. The processing unit 200 and the

respective units

212, 216, 218, 220, 222, 224, 226, 228, and 230 included in the processing unit 200 are executed by the processor 106 illustrated in FIG. 2 reading and executing the game program in the memory 108. It is realized by.

In this embodiment, the player character is moved to an arbitrary position in the game space based on the slide operation. For example, the player character is moved to the vicinity of the position predicted by the player when the ball reaches by a slide operation. If the tap or flick operation is detected when the opponent hit ball is located in the swing field, the player character can hit the opponent hit ball. That is, in the present embodiment, the player character moves within the player's side based on the slide operation, and the game is developed by the player character hitting the ball based on the tap or flick operation. Further, by detecting the tap or flick operation, all or a part of the timing of hitting, the flying direction of the ball, the speed of the ball, and the arrival position of the ball is designated. In the present embodiment, various game parameters can be specified by detecting simple operations such as taps and flick operations, and a complicated game is developed.

FIG. 10 is a schematic diagram when the game space around the player character is projected onto the XY plane. FIG. 10 shows a swing field 1402, a ball 1404, a player character 1406, and two areas 1408. The swing field 1402 is an area where the player character can strike back (hit) a hit ball from the opponent character. In FIG. 10, the player character 1406 holds a racket in the right hand and tries to strike back the ball that has flew with a forestroke. The forestroke is a striking method for hitting a ball that passes the player character's racket holding side (here, the right hand side).

The swing field 1402 is a three-dimensional area (for example, a rectangular parallelepiped) having a predetermined width in the upward direction, the horizontal direction, and the front-rear direction with the player character 1406 as the center, and is defined based on the position of the player character. In the present embodiment, when the ball hit by the opponent character is located in the swing field, if a tap or flick operation is detected, the player character can hit the opponent's hit ball. Therefore, this embodiment provides a game in which a certain period is provided for the timing of detecting tap and flick operations, and the opponent hits the ball easily. In particular, when the display is small, the ball is displayed very small in the display, so the timing at which the ball passes near the player character is very short. By providing a swing field, it is possible to provide a game that is easy to progress (easy to measure timing) to the player.

FIG. 10 shows a player character 1406 whose center coordinates are (xc, yc, 0). The swing field 1402 has a width of xf (that is, from (xc−xf) to (xc + xf)) in the positive and negative directions of the X axis with the center coordinate (xc, yc, 0) of the player character 1406 as the center. It is set to have a width of yf (ie, (yc−yf) to (yc + yf)) in the positive and negative directions of the Y axis, and a width of zf (ie, 0 to zf) in the positive direction of the Z axis. The The values of xf, yf, and zf are variables based on the position of the player character, and are set to be smaller as they approach the net and increase as they approach the base line. That is, the size of the area of the swing field is variable, is the maximum at the baseline, and gradually decreases as it approaches the net. This means that even when the character is placed near the net, if the player hits the ball in the same way as when placed at the baseline, many balls can be taken if the character is placed at the baseline, This is because the game is not interesting.

A straight line passing through the player character having the y-coordinate yc of the player character position and parallel to the X axis in the game space is called a field horizontal line. Two straight lines parallel to the Y axis in the game space at positions shifted by xf and (−xf) in the X axis direction around the x coordinate xc of the player character position are referred to as field vertical lines. The player character may hit the opponent's hit ball also in an area outside the swing field 1402 (two shaded areas 1408 surrounded by a one-dot chain line shown in FIG. 10), that is, an area 1408 beyond the field vertical line. In this case, the player character jumps and hits the opponent's hit ball located in the area 1408 (jump area). The swing field 1402 has an outer edge that defines its range and includes a field vertical line within the outer edge.

Next, a method for specifying various parameters (control value, timing value, and meet value) will be described with reference to FIGS. FIG. 11 shows each landing reference point and the direction of deviation (offset) from the landing reference point of the landing area. Based on the timing value and the meet value, an offset amount (deviation amount) at the center of the landing area from each landing reference point is obtained. Based on the offset amount, an offset range from the landing reference point at the center of the landing region is determined. The landing reference area is set based on the offset area at the center of the landing area and the landing area whose size is determined based on the character parameters of the player character. In the present embodiment, the landing reference area is an area where the ball falls somewhere in this area even if the offset amount is taken into consideration. The control value, timing value, and meet value are used for designating the landing point (or landing reference area) of the ball that lands on the opponent's base, the flight direction of the ball, and the speed of the ball. These parameters are specified based on the positional relationship between the player character when touch-inputted and the ball hit by the opponent character. The values of these parameters may be discrete values (integer) or continuous values.

The control value is a value that is set based on the distance in the Y-axis direction between the ball position of the opponent's hit ball when the touch input is detected (for example, when the touch end position is detected) and the field horizontal line. is there. The control value is largest when touch input is made when the opponent hits the ball on the field horizon (for example, value 8), decreases linearly as the distance from the field horizon increases, and is smallest at the end of the swing field ( For example, value 1) is set. Based on the control value, an object parameter (for example, the speed of the ball returned by the player character) is determined. For example, the larger the control value, the faster the ball is returned.

Similar to the control value, the timing value is set based on the distance between the ball position when the touch input is detected (for example, when the touch end position is detected) and the field horizontal line in the Y-axis direction. However, the value setting method is different. The timing value determines the offset amount of the landing area from each landing reference point. The landing area is an area located in the opponent's base where the ball hit by the player character is randomly landed. The landing area based on the timing value deviates from the landing reference point in the direction of the solid line arrow shown in FIG. The timing value has the smallest absolute value when touch input is made when the opponent hits the ball on the field horizontal line (for example, value 0), and the absolute value increases as the distance from the field horizontal line increases. Then, the absolute value is set to be the largest (for example, value 8). As the timing value, a positive value is set in the positive direction on the Y axis and a negative value is set in the negative direction on the Y axis with respect to the field horizontal line. When the absolute value of the timing value is minimum (that is, a value of 0), it means that a touch input is made when the opponent hit ball is positioned on the field horizontal line. In this case, the landing area is set to a position that is not displaced (not offset) from the landing reference point in the direction of the solid arrow shown in FIG. On the other hand, when the absolute value of the timing value is maximum (for example, the value +8 or -8), the landing area is set at a position that is most shifted (offset) in the left-right direction from the landing reference point. That is, when the absolute value of the timing value is minimum, the landing area is on the first line (dotted arrow shown in FIG. 11) extending from the landing reference point to the outer periphery of the opponent base, and the absolute value of the timing value is the maximum. In this case, the landing area is at a position most shifted from the first line extending from the landing reference point to the outer periphery of the opponent base. For example, in the case of

landing reference points

1 and 3, the first line extending from the landing reference point to the outer periphery of the opponent base is a line extending from the

landing reference points

1 and 3 to the “corner” of the opponent base. Further, in the case of the landing reference point 2, the first line is a line extending from the landing reference point 2 to the “baseline” of the opponent base. Then, the ball hit by the player character lands in a landing area that is offset or not offset.

For example, if a touch input is made when the ball is positioned above the field horizon (positive direction with respect to the Y axis), it is determined that the swing has been made earlier than the preferred timing. When holding the racket in the right hand and hitting it back with a forestroke, the ball hit by the player character is landed in a landing area shifted to the left from the landing reference point. On the other hand, if the touch input is made when the ball is positioned below the field horizontal line (negative direction with respect to the Y axis), it is determined that the swing has been made later than the preferred timing. When holding the racket in the right hand and hitting it back with a forestroke, the ball hit by the player character is landed in a landing area shifted to the right side from the landing reference point. On the other hand, in the case of a backstroke, on the contrary, if it is determined that the swing has been made earlier than the preferred timing, the ball will land in a landing area that is shifted to the right side of the landing reference point, and the ball will strike more than the preferred timing. If it is determined that the swing has been made late, the ball will land in a landing area shifted to the left of the landing reference point.

The meet value is a value set based on the distance in the X-axis direction between the position of the ball when a touch input is made (for example, when the touch end position is detected) and the field vertical line. When the ball is positioned on the left side of the player character, the meet value is set based on the field vertical line on the left side of the player character. The meet value determines the offset amount of the landing area from each landing reference point. The landing area based on the meet value is shifted (offset) from the landing reference point in the direction of the dotted arrow shown in FIG.

As shown in FIG. 11, the direction in which the landing area is offset based on the meet value (the dotted arrow direction in FIG. 11) is the direction in which the landing area is offset based on the timing value (the solid arrow direction in FIG. 11). It intersects almost vertically or vertically. The meet value is largest when touch input is made when the opponent hits the ball on the field vertical line (for example, a value of 8) and moves away from the field vertical line (that is, to the left of the field vertical line (on the X axis). It is set to a smaller value (for example, value 1) as it goes to the right (negative direction) or to the right (positive direction on the X axis). As the ball shifts to the left or right side of the field vertical line, it becomes difficult to hit, so the meat value decreases. When the meet value is the largest (for example, a value of 8), the hit ball is landed in a landing area that is most deviated in a predetermined direction from the landing reference point (that is, at a position where the opponent character is difficult to hit back). To do. On the other hand, when the meet value is the lowest (for example, value 1), the hit ball does not deviate from the landing reference point (that is, at a position where the opponent character can easily hit back), and landed in the landing area. . That is, the landing area is on the second line (solid arrow shown in FIG. 11) that is substantially perpendicular to the first line (dotted arrow shown in FIG. 11) through the landing reference point when the meet value is minimum. When the meet value is the maximum, the landing area is at the position farthest from the second line. The higher the meet value, the more the player character's hit ball will land in the landed area shifted from the landing reference point toward the base line, side line, and net.

As described above, the control value, the timing value, and the meet value are obtained based on the information about the touch input and the information about the ball located in the game space. Then, the processing unit 200 can determine the speed of the returning ball or the offset amount of the landing area from the landing reference point based on the control value, the timing value, and the meet value.

11 is set such that the minimum radius is 0.1 m and the maximum radius is 0.4 m, for example. The size of the landing area is variable according to the character parameters of the player character, the game stage, and the like, and is set in advance for each game. For example, the size of the landing area depends on the character level, various game parameters (for example, parameters determined for each shot (top spin, slice, lob, drop, smash, volley, air shot, rising), through game play. The average value of the acquired control value and / or meet value). Since the landing point is determined pinpointed when the landing area is narrow, for example, the landing area is large when the level of the player character is low, and the landing area is narrowed as the level increases. FIG. 11 shows that the offset direction differs depending on the selected landing reference point. For example, when the landing reference point 1 of the opponent base is selected, the landing area moves to the corner of the opponent base as the meet value increases, and the side line or the timing value increases as the timing value increases. The center of the landing area moves to the baseline.

12A and 12B are diagrams exemplifying the deviation of the landing area from the landing reference point 1 determined according to the timing value and the meet value. The black circle indicates the landing reference point 1 and the gray circle indicates the landing area. 12A shows a case where the landing area is narrow, and FIG. 12B shows a case where the landing area is wide. Also, the solid line arrows in FIGS. 12A and 12B show one mode of deviation from the landing reference point of the landing area when the timing value changes, and the dotted line arrow shows from the landing reference point of the landing area when the meet value changes. One mode of deviation is shown. As shown in FIGS. 12A and 12B, as the meet value increases, the landing area moves toward the corner of the opponent base, and toward the side line or the baseline as the absolute value of the timing value increases. The landing area moves. When the meet value is maximum, the landing area moves to the corner of the opponent's base, but the landing area should be within the opponent's base. This is to prevent the ball from going out when the meat value is maximum.

The area 1602 is a landing area determined by the offset / landing point determination unit 226 when the timing index is +4 and the meet value is 4. An area 1604 is a landing area when the timing index is −8 and the meet value is 4. A region 1606 is a landing region when the timing value is +8 and the meet value is 4. The offset / landing point determination unit 226 determines a landing point at random within the determined landing area. In the present embodiment, when the absolute value of the timing value is the maximum, the center of the landing area is located on the side line and the base line. Therefore, when the landing area is the

area

1604 or 1606, the ball may land on the area beyond the base line or the side line and be out. As shown in FIG. 12A, when the landing area is narrower, when a suitable timing value and meet value are acquired (that is, when the timing value is 0 and the meet value is 8), the ball hits the corner (corner) of the opponent's base more. Can be made.

FIGS. 13A to 13H are diagrams respectively illustrating the deviation of the landing area from the landing reference points 2 to 9 determined according to the timing value and the meet value. FIG. 13A shows one aspect of the deviation of the landing area from the landing reference point 2. The higher the meet value, the closer the landing area is to the baseline. As the absolute value of the timing value increases, the landing area shifts to the left and right. For example, in the case of a right-handed forehand, if the ball is hit in the area above the field horizon in the swing field on the Y axis (hit the ball earlier), the landing area in the opponent's position shifts to the left. FIG. 13B shows an aspect of the deviation of the landing area from the landing reference point 3. The higher the meet value, the closer the landing area is to the corner. As the absolute value of the timing value increases, the landing area shifts to the left and right. 13C shows the deviation of the landing area from the landing reference point 4, FIG. 13D shows the deviation of the landing area from the landing reference point 5, FIG. 13E shows the deviation of the landing area from the landing reference point 6, and FIG. 13G shows the deviation of the landing area from the reference point 7, FIG. 13G shows the deviation of the landing area from the landing reference point 8, and FIG. 13H shows the deviation of the landing area from the landing reference point 9. As shown in FIGS. 13A, 13D, and 13G, when the landing reference point 2, the landing reference point 5, and the landing reference point 8 are selected, the landing area does not exceed the base line or the side line. The landing ball will never be out.

Hereinafter, the flow of processing performed in the processing unit 200 will be described with reference to FIGS. 9 and 14.
First, in step S1, the landing area size determination unit 220 sets the size of the landing area according to the character parameters of the player character and some or all of the various game parameters. For example, the landing area size determination unit 220 narrows the landing area as the character level increases, and widens the landing area as the character level decreases.

Next, in step S2, the touch input detection unit 212 detects information related to touch input to the touch panel by the player made to the player character displayed on the display.

Next, in step S3, based on the information regarding the touch input detected in step S2, the touch input detection unit 212 determines the type of touch input (slide operation, tap operation, flick operation). If the touch input is a slide operation, the process proceeds to step S4. If the touch input is a tap or flick operation, the process proceeds to step S5.

If it is determined in step S3 that the operation is a slide operation, the process proceeds to step S4. In step S4, the object motion control unit 218 moves the player character within the player's own space in the game space based on the distance and direction from the touch start position to the touch end position in the information related to the touch input detected by the touch input detection unit 212. Move with. Then, the display processing unit 230 displays the player character controlled by the object motion control unit 218 on the display 114, and returns to step S2.

If it is determined in step S3 that the operation is a tap operation or a flick operation, the process proceeds to step S5. In step S5, the swing field setting unit 222 sets the swing field in the game space based on the current position of the player character in the game space. At this time, the display processing unit 230 may output the outer edge defining the width of the swing field and the field horizontal line to the display.

Next, in step S <b> 6, the timing determination unit 224 detects the position of the ball in the game space when the touch end position is detected by the touch input detection unit 212. Then, the timing determination unit 224 determines whether or not a touch input has been made in step S2 when the detected ball is positioned within the set swing field.

Next, when it is determined that a touch input is made in step S2 when the ball is positioned in the swing field, the process proceeds to step S7. In step S <b> 7, the landing reference area determination unit 216 determines a plurality of preliminarily defined on the opponent's ground in the game space based on the direction from the touch start position to the touch end position detected by the touch input detection unit 212. One landing reference point is determined among the landing reference points.

Next, in step S8, the offset / landing point determination unit 226 determines the amount by which the landing region having the size determined by the landing region size determination unit 220 is offset from the landing reference point. Further, the offset / landing point determination unit 226 randomly determines the landing point in the offset landing region.

Next, in step S9, the object motion control unit 218 selects a motion to take back the racket and hit the ball based on the position of the ball and the position of the player character when the touch end position is detected. Then, the player character is caused to perform the selected action. The action of taking back and hitting the ball is defined in advance for each swing pattern. More specifically, the object motion control unit 218 performs a batting motion (swing pattern, swing) to be performed on the player character based on the position of the ball in the swing field when the touch end position is detected and the position of the player character. Swing time) is appropriately selected. Basic swing patterns include forestroke, backstroke, volley, and smash. The forestroke is a hitting method in which a ball that passes the player character's racket side (here, the right hand side) is hit. The back stroke is a striking method in which the player character hits a ball passing through the side opposite to the side having the racket (here, the left hand side). Volley is a batting method in which the ball is shot into the opponent's base before the ball bounces into the base. The smash is a striking method in which a ball passing on the figure of the player character is shot into the opponent base at a steep angle. For example, when the ball is positioned on the right side of the character, the object motion control unit 218 causes the character to perform a forestroke, and causes the character to perform volley when the character is positioned near the net. The object motion control unit 218 varies the motion to be performed on the character depending on the positional relationship between the ball and the character and the distance of the character from the net.

Furthermore, the object motion control unit 218 varies the take-back motion according to the speed of the opponent hit ball and the positions of the player character and the opponent hit ball. For example, if the position of the opponent's hit ball when the touch end position is detected is sufficiently far from the player character, the player character is caused to perform all of the predetermined actions to take back and hit the ball. If the position of the opponent's hit ball when the touch end position is detected is close to the player character, there is no time for the player character to perform all the actions, so the action of hitting the ball with a predetermined takeback Among them, a part (for example, the first action) is omitted and the player character is made to perform.

Further, the object motion control unit 218 moves the ball to land on the landing point determined by the offset / landing point determination unit 226. At this time, the hitting speed determination unit 228 determines the object parameter of the ball hit by the player character based on the meet value and the control value. For example, the speed (object parameter) of the ball returned by the player character is determined based on one or both of the meet value and the control value. Further, the hitting speed determination unit 228 uses a value obtained by multiplying the meat value and the control value, a unique value for each ball type (serve, drop), and a character parameter (for example, a character level) by the player character. The speed of the returned ball may be determined.

Then, the display processing unit 230 outputs an image signal for moving and displaying the player character and the ball controlled by the object motion control unit 218 in the game space to the display 114.

In step S6, when the ball when the touch input is detected is located outside the swing field, the process proceeds to step S10. In step S10, the player character that performs the various actions selected cannot hit the ball, and the player character swings idle.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. Those skilled in the art will appreciate that various modifications of the embodiments can be made without departing from the spirit and scope of the invention as set forth in the appended claims.
