Description

  The present invention relates to an image generation apparatus and the like that generate an image in which at least a first object is operated according to the relationship between the first object and the second object existing in a virtual space.

  2. Description of the Related Art Conventionally, a method of generating an object such as a character existing in a virtual three-dimensional space by moving the object and performing a perspective transformation using a virtual camera has been widely applied to three-dimensional video games. In such a three-dimensional video game, in the virtual three-dimensional space, in addition to the player character that moves according to the operation of the player, there are a large number of objects such as enemy characters that face the player character.

  Thus, when a large number of objects exist in the virtual three-dimensional space, the motion of a certain object is influenced by an external force received from another object. Accordingly, for example, when the first object (weapon possessed by the player character) hits the second object (enemy character), the motion data of the first object is set to the bone set in the first object. There has been an image generation system that attempts to reproduce the influence of an external force that a certain object has received from another object by changing the individual blend ratio of the motion data every time (for example, see Patent Documents 1 and 2).

JP 2003-62326 A (paragraphs 0099 to 0113) JP 2003-67773 A (paragraphs 0103 to 0117)

  However, human and animal behaviors in the real world are influenced by the presence of other objects, even if they are not directly subjected to external forces from other objects. For example, to act while constantly monitoring an object (for example, to follow a ball in a ball game scene), or to change the direction to avoid an object (for example, to avoid an obstacle) Many of the behaviors influenced by other objects such as are performed unconsciously.

  On the other hand, in the conventional game device, the operation pad on which the player inputs an action instruction to the character has a limited number of direction keys for inputting a direction and buttons for inputting individual instructions. The types of instructions that can be given are also limited. For this reason, it is impossible to input different instructions depending on the presence of other objects, and when the same operation is instructed, the same operation may be performed regardless of where the other object exists.

  On the other hand, if the types of instructions that can be input from the operation pad are increased, there is a problem that the game becomes too complicated. Furthermore, even if the types of instructions that can be input from the operation pad are increased, how the character behaves in relation to each input, or how other objects are placed in relation to the character It is difficult for the player to intuitively judge this. For this reason, there is a problem that it is easy for an instruction not intended by the player to be input or an input of the player's instruction to be delayed.

  In the present invention, in the virtual space where the first object and the second object exist, an image in which the first object performs different actions depending on the presence of the second object even when the same action is instructed. It is a first object of the present invention to provide an image generation apparatus and method that can be generated, and a program and a recording medium used therefor.

  The present invention can generate an image in which a positional relationship between a first object and a second object is determined by an operator's intuitive input in a virtual space where the first object and the second object exist. A second object of the present invention is to provide a generation apparatus and method, and a program and a recording medium used therefor.

  In order to achieve the above object, an image generation apparatus according to a first aspect of the present invention generates an image obtained by operating at least a first object among a first object and a second object existing in a virtual space. When the operation input unit inputs an instruction to move the first object in the virtual space according to an operation of the operator, and when the operation instruction is input from the operation input unit, the first Corresponding to the instruction input from the action input means so that the position relation judging means for judging the positional relation between one object and the second object, and different actions depending on the judgment result of the position relation judging means An object operation means for causing at least the first object to perform an action; and a first object operated by the object action means. An object, an image generating means for generating an image comprising a second object, characterized by comprising a display control means for displaying the generated image of the image generating unit on a display unit.

  In the image generating apparatus according to the first aspect, when an instruction for moving the first object is input from the motion input unit, the first object is in accordance with the positional relationship with the second object. It is made to work. For this reason, the first object does not perform the same operation regardless of the presence of the second object, and the first object can be prevented from performing an unnatural operation. In addition, since the operator does not have to use different instructions input by the operator in order to cause the first object to perform an appropriate action due to the presence of the second object, the instruction input for operating the first object is input. Is not complicated.

  In the image generating apparatus according to the first aspect, the motion input unit is configured to move the position of the first object from a current position toward any one of a plurality of predetermined directions. It may include moving input means for inputting an instruction. In this case, when the movement instruction is input from the movement input unit, the object movement unit has a speed corresponding to the direction corresponding to the input instruction and the determination result of the positional relationship determination unit. The first object may be moved in a direction corresponding to the input instruction in the virtual space.

  Here, the first object moves in the direction corresponding to the instruction input from the movement input means in the virtual space, but the speed changes according to the positional relationship with the second object. For this reason, it is possible to prevent the first object from moving in the virtual space at an unnatural speed regardless of the presence of the second object.

  In the image generating apparatus according to the first aspect, the positional relationship determination unit is configured to direct the position of the first object from the position of the first object to the position of the second object as the positional relationship between the first object and the second object. The direction may be determined.

  In this case, in the image generating apparatus according to the first aspect, the direction corresponding to the instruction input from the movement input unit is within the first specific range with respect to the direction determined by the positional relationship determination unit. When the input direction determination means further determines whether or not the object movement means is determined to be within the first specific range by the input direction determination means, the first specification The first object can be moved at a higher speed than when it is determined to be out of the range.

  In addition, the object movement means may be configured such that the smaller the angle formed between the direction corresponding to the instruction input from the movement input means and the direction from the position of the first object toward the position of the second object, One object can be moved at high speed.

  In these cases, the image generating apparatus according to the first aspect follows the movement of the first object in the virtual space by the object operation unit, and moves the second object in the virtual space. Second object moving means for moving can be provided. For example, when the first object is like a character that moves the second object along with the first object, the first object depends on the position of the second object relative to the traveling direction. The ease of moving the objects should also change. Here, the first object can be moved at a natural speed according to the position of the second object in the traveling direction.

  In the image generating apparatus according to the first aspect, the motion input unit is configured to move the position of the first object from a current position toward any one of a plurality of predetermined directions. The position relation determining means may include a movement input means for inputting an instruction, and the positional relationship determination means may determine the position of the second object from the position of the first object as the positional relationship between the first object and the second object. The relationship with the direction toward the position may be determined. In this case, when the movement instruction is input from the movement input unit, the object movement unit performs different operations depending on the direction corresponding to the input instruction and the determination result of the positional relationship determination unit. The first object may be performed.

  In this case, the first object performs an action corresponding to the direction corresponding to the instruction input from the movement input means (such as a change of direction in the direction). Depending on the direction toward the second object. For this reason, it is possible to prevent the first object from moving in an unnatural direction regardless of the presence of the second object.

  In the image generating apparatus according to the first aspect, the motion input unit is configured to move the position of the first object from a current position toward any one of a plurality of predetermined directions. The image generation apparatus according to the first aspect may include a movement input unit that inputs an instruction. When the movement instruction is input from the movement input unit, the first object is the virtual object. First object direction detection means for detecting a direction facing in the space may be further provided. In this case, the object movement means is responsive to the determination result of the positional relationship determination means, the direction detected by the first object direction detection means, and the direction corresponding to the instruction in which a movement instruction is input from the movement input means. It is possible to cause the first object to perform an action according to the above.

  In this case, the object movement means is responsive to the determination result of the positional relationship determination means, the direction detected by the first object direction detection means, and the direction corresponding to the instruction in which a movement instruction is input from the movement input means. Accordingly, the direction of the first object may be changed to a direction corresponding to the instruction input from the movement input unit.

  In this case, the first object performs an action corresponding to the direction corresponding to the instruction input from the movement input means (such as a direction change in the direction). The action is the same as that of the second object. And the direction in which the first object itself is facing. Therefore, it is possible to prevent the first object from moving in an unnatural direction or facing in an unnatural direction regardless of the presence of the second object.

  Here, in the image generating apparatus according to the first aspect, the direction corresponding to the instruction input from the movement input unit is within the second specific range with respect to the direction determined by the positional relationship determination unit. First detection direction determination means for determining whether or not the direction corresponding to the instruction input from the movement input means is outside the third specific range with respect to the direction detected by the first object direction detection means And a second detection direction determining means for determining In this case, when the object movement means is determined to be outside the third specific range by the second detection direction determination means, the object movement means is within the second specific range by the first detection direction determination means. When determined, the direction of the first object can be changed to a direction corresponding to the instruction input from the movement input means at a higher speed than when determined to be outside the second specific range.

  The object movement means is determined to be within the second specific range by the first detection direction determination means when the second detection direction determination means determines that the object movement means is outside the third specific range. The direction of the first object may be changed to the direction corresponding to the instruction input from the movement input means without moving the position of the first object in the virtual space.

  In these cases, for example, when the first object is like a character that manipulates the second object, it is finally the same direction (here, the instruction input from the movement input means) When the second object is present and when it is in a completely different direction from the beginning, the direction when the first object is turned in that direction. The ease should also change. Here, the direction of the first object can be changed at a natural speed depending on the range of the direction of the second object relative to the direction in which the first object is going. .

  The first detection direction determination unit is configured to detect the first detection direction when the direction corresponding to the instruction input from the movement input unit is substantially in the same direction as the direction determined by the positional relationship determination unit. The second detection direction determination means determines that the direction corresponding to the instruction input from the movement input means is substantially relative to the direction detected by the first object direction detection means. When in the same direction, it can be determined to be within the third specific range.

  When the movement input means inputs an instruction for moving the first object in a plurality of directions in which the angles formed by adjacent directions are equally divided, the first detection The direction determination means and the second detection direction determination means can determine whether or not they are substantially in the same direction for each of the equally divided angle ranges.

  As described above, the first detection is performed by determining whether the direction is substantially the same as the direction corresponding to the instruction input from the movement input means, and whether the direction is within the second specific range and the third specific range. The determination by the direction determination unit and the second detection direction determination unit can be easily performed.

  The image generation apparatus according to the first aspect may further include a motion data storage unit that stores a plurality of motion data defining the operation of the first object. In this case, the object motion means operates the first object using motion data corresponding to an action to be performed by the first object among a plurality of motion data stored in the motion data storage means. Can be made.

  Here, the object motion means blends the plurality of motion data stored in the motion data storage means at a blend rate according to the motion to be performed by the first object, and uses the blended motion data. The first object can be operated.

Thus, the second object is arranged with respect to the position of the first object moving in the virtual space. In this way, when the operator tries to place the second object at a desired position with respect to the first object moving in the virtual space, it is only necessary to input the coordinate position from the coordinate position input means. Intuitive input operation is possible and the operation is not complicated.

That is, the player character may change depending on the progress of the game.

  Each character of the player team including the player character and each character of the opponent team exist on a basketball court (hereinafter simply referred to as “court”) formed in a virtual three-dimensional space, and depending on the progress of the game Works on the court. Balls also exist on the court formed in the virtual three-dimensional space, and the ball is carried on the court by the action of each character, and put into the goal of the enemy team (the opponent team for the player team). Score.

  The movement of other characters of the player team is controlled by the CPU core 21 of the game apparatus 1 in accordance with the movement of the ball or the player character. The actions of the characters of the opponent team are all controlled by the CPU core 21 of the game apparatus 1. When the player team is on the defense side or is a loose ball, the player character is determined based on the position of the ball, the position of the character of the opponent team, etc., and is operated according to an instruction from the player. Since this is not directly related to the present invention, the description thereof is omitted.

  FIG. 3 is a diagram showing an example of a display screen when the player team is on the offense side in the basketball game according to this embodiment. As shown in FIG. 3A, the first LCD 11 has a virtual camera with a viewpoint set at a predetermined position with the player character 100 carrying the ball 110 (here, dribbling) as a reference point. Thus, an image obtained by perspective-transforming the virtual three-dimensional space including the coat is displayed. Characters 101 to 104 of the player team other than the player character 100 and characters 121 to 125 of the opponent team are displayed on the first LCD 11 if they exist in the range subject to the perspective transformation with the player character 100 as a reference.

  The position of the viewpoint of the virtual camera is determined on the back side of the player character 100 when the player character 100 stops moving on the court or when a new player character 100 is set by receiving a pass or the like. The position is set at a predetermined distance in the direction (the direction opposite to the direction of the route 100R, which is the reference direction of the player character 100) (provided that there is no obstacle between the viewpoint and the player character 100).

  The player character 100 may change its direction (that is, the direction of the route 100R) by changing the position where the ball 110 is dribbling by touching the touch panel 13 as described later. However, the direction change is smaller than the change in the position where the ball 110 is dribbling. Unless the position of the player character 100 on the court does not change except in the case of a quick turn described later, the viewpoint position does not change. If the player character 100 moves on the court by operating the direction indicating switch 14c, the viewpoint position moves following the movement. Also in the case of a quick turn described later, the position of the viewpoint moves in the direction of the back side of the player character 100 after the turn.

  As shown in FIG. 3B, the second LCD 12 has an image of an xz plane (y direction, ie, a plane perpendicular to the height direction) of the virtual three-dimensional space with the position of the player character 100 as the center. Is displayed. The displayed range is set such that the player character 100 is the center and the viewpoint of the virtual camera for displaying the image on the first LCD 11 is in the downward direction. In the example of FIG. 3A, since the straight line connecting the viewpoint and the player character 100 matches the vertical direction of the court, the display range of the second LCD 12 is as shown in FIG. It becomes. Of the characters existing in this display range, the characters 100 to 104 of the play team (including the player character 100) are white circles, and the characters 121 to 125 of the opponent team are black circles, indicating the positions on the court.

  The vertical and horizontal directions of the display range of the second LCD 12 do not necessarily coincide with the vertical and horizontal directions of the coat. That is, the vertical and horizontal directions of the display range are inclined with respect to the vertical and horizontal directions of the court in accordance with the direction of a straight line connecting the player character 100 serving as the reference point and the viewpoint of the virtual camera. The input direction (eight directions) of the direction indicating switch 14c corresponds to the display direction of the second LCD 12, and the movement direction of the player character 100 on the court when the direction indicating switch 14c is operated includes the display range, the court, and the court. It is determined according to the inclination angle of.

  Next, in the basketball game according to this embodiment, the operation of the player character 100 when the player team is on the offense side will be described. The actions of the player character 100 in this case include dribbling the ball stopped at an arbitrary position on the court, moving on the court while dribbling the ball 110, and passing the ball to another character on the player team ( In this case, the character that has received the pass becomes a new player character 100), and there are actions such as shooting.

  A case where the player character 100 stops at an arbitrary position on the court and dribbles the ball will be described. When the player character 100 is stopped at an arbitrary position on the court, the player character 100 continues to dribble the ball 110 according to the motion data. The position of the ball 110 with respect to the position of the player character 100 is arbitrarily switched within the reach of the player character 100 according to the position where the touch panel 13 is touched. Further, the hand for dribbling the ball 110 can be switched according to the position where the touch panel 13 is touched. However, the change of the position of the ball 110 and the dribbling hand is due to the change of motion data for dribbling the player character 100 by touching the touch panel 13.

  Since the ball 110 can be dribble at an arbitrary position according to the position touched on the touch panel 13 as described above, the motion data when the player character 100 dribbles the ball 110 is prepared for each position of the touch panel 13. The amount of motion data will be enormous. Therefore, in the basketball game according to this embodiment, motion data is written in the ROM 171 in association with only specific coordinate positions (hereinafter referred to as specific coordinates) on the touch panel 13, and when other positions are touched, Motion data stored in the ROM 171 is blended according to the coordinates of the touched position, and motion data for causing the player character 100 to perform a dribbling motion is generated.

  FIG. 4 is an explanatory view of motion blending when the player character 100 stops at an arbitrary position on the court and performs dribbling. Although the player character 100 can dribble the ball 110 with either the right hand or the left hand, FIG. 4 illustrates motion blending when dribbling with the right hand. When dribbling with the left hand, it can be considered as an inverted pattern in FIG.

  As shown in FIG. 4A, the area on the touch panel 13 is divided into nine areas of 3 rows and 3 columns (1) to (9) at equal intervals. When the player character 100 is dribbling with the right hand, as shown by hatching in the figure, three areas (2), (5), (8) in the middle row (vertical direction) The three areas (3), (6), and (9) in the right column are set as areas that do not change the dribbling hand. In addition, six specific coordinates 201 to 206 are set in total at the positions of the four vertices of the rectangle formed by these six areas and the positions of the midpoints of the two vertical sides.

  The specific coordinates 201 to 206 are associated with motion data corresponding to each position. If the coordinate of the touched position on the touch panel 13 when the player character 100 is dribbling with the right hand is one of the specific coordinates 201 to 206, the motion associated with the specific coordinate corresponding to the touched position The data is loaded into the WRAM 22 and used as it is as motion data for causing the player character 100 to dribble. When a new player character 100 is set by receiving a pass or the like, motion data corresponding to the specific coordinates 201 is loaded into the WRAM 22 and used as a default. This is motion data for dribbling the ball 110 in front of the player character 100 (that is, in the direction of the route 100R).

  When a position other than the specific coordinates 201 to 206 is touched within the range of areas (2), (3), (5), (6), (8), and (9) on the touch panel 13, The coordinates of the touched position are stored in the WRAM 22. As the coordinates of the touched position on the touch panel 13, at least the latest two times are stored. When a new player character 100 is set, all the coordinates previously stored in the WRAM 22 are deleted, and the specific coordinates 201 corresponding to the motion data used as a default are used as the coordinates of the latest touched position. Stored in the WRAM 22. According to the coordinates of this position, motion data corresponding to the specific positions 201 to 206 is blended to generate motion data.

  For example, as shown in FIG. 4B, it is assumed that the position T (x1, y1) in the area (3) is touched. Since the y coordinate y1 of the position T is larger than the y coordinate 0 of the vertices 201 and 204 on the upper side and smaller than the y coordinate 95 of the specific coordinates 202 and 205 of the middle point, the four specific coordinates 201, 202, 204, and 205 are present. Are selected as specific coordinates to be blended with motion data. When the vertex 201 to 206 and one of the x coordinate and the y coordinate are touched at the same position, only two specific coordinates are selected.

  Next, the upper side (side connecting the specific coordinates 201, 204), the bottom side (side connecting the specific coordinates 202, 205), the left side (specific coordinates 201, 205) surrounded by the selected specific coordinates 201, 202, 204, 205 202), the right side (side connecting the specific coordinates 204, 205), and the position T when the positions of intersections of straight lines passing through the position T and parallel to these sides are Th, Tu, Tl, Tr. The ratio of the length between the position Th and the length between the position T and the position Tu is H: U, the length between the position T and the position Tl, and the ratio of the length between the position T and the position Tr is L: Suppose that it became R.

  In this case, the blend ratios B (201), B (202), B (204), and B (205) of the motion data corresponding to the specific coordinates 201, 202, 204, and 205 are the equations shown in FIG. Is required. As can be seen from these mathematical expressions, the blend rate is higher as the motion data corresponds to the specific coordinate located near the touched position T on the touch panel 13. The motion data corresponding to the specific coordinates 201, 202, 204, and 205 are blended at the obtained blend rates B (201), B (202), B (204), and B (205), and the player character 100 plays the ball. Motion data for dribbling 110 is generated and stored in the WRAM 22.

  When the motion data corresponding to the new touch position is blended and stored in the WRAM 22, the motion data before touching the touch panel 13 is transferred to the motion data corresponding to the newly touched position (however, The player character 100 is moved. However, depending on the relationship between the previous touch position and the current touch position, the motion data before touching is temporarily shifted to the motion data of the joint motion, and the player character 100 is moved to the newly touched position. The player character 100 is moved by moving to the corresponding motion data.

  On the other hand, when the player character 100 is dribbling with the right hand, if the position within the three areas (1), (4), (7) on the left side of the touch panel 13 is touched, the ball 110 The dribbling hand is switched to the left hand. FIG. 5 is an explanatory diagram of the case where the player character 100 switches the hand that dribbles the ball 110 from the right hand to the left hand. When the hand for dribbling the ball 110 is switched from the left hand to the right hand, the pattern in which the left and right in FIG. 5 are reversed may be considered.

  For example, as shown in FIG. 5A, it is assumed that the position t included in the area (1) on the touch panel 13 is touched while the player character 100 is dribbling the ball 110 with the right hand. . Since this position does not correspond to a position where the right hand can be dribble, the specific coordinates 221 corresponding to the touched position t among the specific coordinates corresponding to the dribbling with the left hand as shown in FIG. 5B. ˜224 are selected as specific coordinates to be blended with motion data. Here, the generation of motion data may be performed by a method similar to that shown in FIGS.

  When the player character 100 switches the hand that dribbles the ball 110, the motion data before touching the touch panel 13 is not directly transferred to the motion data corresponding to the newly touched position. After moving from the motion data before touching to the motion data of the joint motion once to move the player character 100, the player character 100 is moved to the motion data corresponding to the newly touched position. .

  Next, the connection motion will be described. FIG. 6 is an explanatory diagram of a connection motion. As described above, the linkage motion is always inserted when the player character 100 dribbles by moving the ball 110 from the right hand to the left hand. Even when the player character 100 does not change the ball, the position touched last time is included in the range of the areas (1) to (3), and the positions touched this time are the areas (7) to (7). 9) or when the position touched last time is included in the area (7) to (9) and the position touched this time is in the area (1) to (3). Even when included in the range, a linkage motion is inserted.

  The joint motion is also for causing the player character 100 to move by reproducing the motion data, but differs depending on the difference between the area where the previous touch panel 13 is touched and the area where the touched position is included this time. Motion data is prepared and stored in the ROM 171 in advance. As connection motions when the player character 100 dribbles the ball 110 with the right hand before touching the new touch panel 13, 26 types of connection motions shown in FIG. 6A are prepared.

  Here, for example, R (3) indicates that the ball 110 is dribbling with the right hand based on the touch of the position included in the area (3). L (4) indicates dribbling the ball 110 with the left hand based on the touch of the position included in the area (4). As a connection motion when the player character 100 dribbles the ball 110 with the right hand before touching the new touch panel 13, 26 types of connection motions in which the pattern shown in FIG. Has been.

  As an example of the connecting motion, for example, the connecting motion of R (2) → L (1) includes an operation in which the player character 100 switches the dribbling hand of the ball 110 from the right hand to the left hand. In the connecting motion of R (2) → R (8), the motion is changed from a motion in which the player character 100 dribbles at a position corresponding to the area (2) to a motion to dribble at a position corresponding to the area (8). In the middle, an operation of once dribbling at an intermediate position is included.

  When a connection motion is inserted, the motion data generated based on the position touched on the touch panel 13 this time through the motion data of the connection motion from the motion data generated based on the position touched on the touch panel 13 last time. Then, the player character 100 is moved. Here, as shown in FIG. 6B, during the transition from the motion data generated based on the position touched on the touch panel 13 last time to the motion data of the joint motion, frame interpolation (start interpolation) is performed for a predetermined number of frames. ) Is done. Also, frame interpolation (end interpolation) is performed for a predetermined number of frames during the transition from the motion data of the joint motion to the motion data generated based on the position where the touch panel 13 is touched this time.

  Next, a case where the player character 100 moves on the court while dribbling will be described. An instruction for the player character 100 to move on the court is input in response to an operation of the direction instruction switch 14c by the player. The player character 100 moves while dribbling the ball 110 in the direction input from the direction indicating switch 14c. Motion data for the motion of the player character 100 is also prepared in advance and stored in the ROM 117, and is reproduced by being blended with dribble motion data.

  In the basketball game according to this embodiment, the speed at which the player character 100 moves changes according to the position where the ball 110 is dribbling. FIG. 7 is an explanatory diagram showing the relationship between the position where the ball 110 is dribbling and the moving speed of the player character 100. Here, it is assumed that the direction of the route 100R of the player character 100 is already facing the direction input from the direction indicating switch 14c, and the player character 100 moves in the input direction (movement direction 100D). .

  As shown in FIG. 7A, when the ball 110 is in the moving direction 100D of the player character 100, that is, when the direction from the player character 100 toward the ball 110 coincides with the moving direction 100D, the player character 100 It moves on the court at a speed V. In this case, it is only necessary to move the player character 100 while reproducing the motion data for movement at a normal speed.

  As shown in FIG. 7B, when the angle formed by the direction from the player character 100 toward the ball 110 and the moving direction 100D is θ1, the player character 100 moves at a speed Vcos (θ1 / 2). Thus, the speed becomes slower than the speed V when the ball 110 is in the moving direction 100D. Further, as shown in FIG. 7 (c), when the angle formed by the direction from the player character 100 toward the ball 110 and the moving direction 100D is θ2, which is larger than θ1, the player character 100 determines that the velocity Vcos (θ2 / 2), which is slower than the speed Vcos (θ1 / 2) when the angle is θ1. In these cases, not only the moving speed of the player character 100 is controlled, but the playback speed of the motion data is also increased to the normal cos (θ1 / 2) times and cos (θ2 / 2) times, and the speed V This is slower than when the player character moves.

  Further, when the player character 100 moves on the court, the direction of the route 100R must be in the traveling direction, and the direction input from the direction indicating switch 14c matches the direction of the route 100R. If not, first, the direction of the route 100R is changed, and then the player character 100 moves on the court. When changing the direction of the route 100R, when the ball 110 is present in advance within a predetermined range from the direction input from the direction indicating switch 14c, the direction of the route 100R of the player character 100 is changed by a technique called quick turn.

  FIG. 8 shows a normal turn when the ball 110 does not exist within a predetermined range from the direction input from the direction indicating switch 14c, and when the ball 110 exists within a predetermined range from the direction input from the direction indicating switch 14c. It is explanatory drawing of no quick turn. Here, the case where there is an upward input from the direction indicating switch 14c in a state where the route 100R of the player character 100 is directed rightward is described as an example.

  As shown in FIG. 8 (a), when the player character 100 has a route 100R facing rightward and there is an upward input from the direction indicating switch 14c, the ball is outside the range of ± θ3 from the moving direction 100D. 110 is present. In this case, as shown in FIG. 8B, the player character 100 changes direction until the direction of the route 100R coincides with the moving direction 100D while dribbling the ball 110. The ROM 117 also stores direction change motion data in advance and is reproduced by blending with dribble motion data. Although it depends on the position where the ball 110 originally existed, it takes at least about a dozen frames before the route 100R faces the moving direction 100D.

  On the other hand, as shown in FIG. 8C, when there is an upward input from the direction indicating switch 14c with the route 100R of the player character 100 facing the right direction, it is within the range of ± θ3 from the moving direction 100D. It is assumed that the ball 110 exists. In this case, as shown in FIG. 8D, the player character 100 immediately turns the direction of the route 100R in the moving direction 100D. However, frame interpolation of several frames may be performed when the direction is changed.

  In addition, while the player character 100 moves on the court while dribbling the ball 110 by operating the direction instruction switch 14c, the hand and position where the ball 110 is dribble can be changed by touching the touch panel 13. The operation in this case can be realized by combining the processing of the above-described operations (however, motion data different from that used when stopping and dribbling may be used as a linkage motion). Further, since the operation of the pass and the chute is not directly related to the present invention, the description thereof is omitted.

  Hereinafter, processing for playing the basketball game according to this embodiment in the game apparatus 1 shown in FIGS. 1 and 2 will be described. In the progress of the game, processing such as switching of the player character is also performed when the character of the opponent team possesses the ball or the character that actually possesses the ball among the characters of the player team changes. However, here, only the process related to the present invention, that is, only the process of moving the player character who actually owns the ball will be described.

  FIG. 9 is a flowchart showing a process for moving the player character 100 when the player team is on the offense side in the basketball game. The process of this flowchart is a process in which the CPU core 21 executes a game program loaded from the ROM 171 of the cartridge 17 to the WRAM 22. When this process is started for the first time, the specific coordinates for dribbling the ball 110 with the right hand are set as defaults.

  First, the CPU core 21 determines whether the touch panel 13 is touched and any coordinate position is input (step S101). If the coordinate position is input from the touch panel 13, the CPU core 21 performs a touch-time process whose details will be described later (step S102). Then, it returns to the process of step S101 again. If the coordinate position is not input from the touch panel 13, the CPU core 21 determines whether any one of the eight directions is input from the direction instruction switch 14c (step S103). If any direction is input from the direction indicating switch 14c, a direction input process, which will be described later in detail, is performed (step S104). Then, it returns to the process of step S101 again.

  If no direction is input from the direction indicating switch 14c, the CPU core 21 determines whether there is another input from the operation switch unit 14 (step S105). When there is another input from the operation switch unit 14, the CPU core 21 performs processing corresponding to the input (for example, causing the player character 100 to shoot or pass another character) (step S106). . Then, it returns to the process of step S101 again. If there is no other input, the CPU core 21 moves the player character 100 in accordance with the latest motion data stored in the WRAM 22 (step S107). Then, the process returns to step S101.

  FIG. 10 is a flowchart showing in detail the touch processing in step S102. In the touch processing, the CPU core 21 stores the coordinates of the touched position input from the touch panel 13 in the WRAM 22 (step S201). Next, the CPU core 21 is currently dribbling the ball 110 with the left hand of the player character 100 and the touched position on the touch panel 13 is one of the areas (3), (6), and (9). It is determined whether it falls within the range (step S202).

  If the player character 100 is dribbling the ball 110 with the right hand or the touched position is outside the range of the areas (3), (6), and (9), the CPU core 21 further determines the player character 100. Is dribbling the ball 110 with the right hand and determines whether the position touched on the touch panel 13 is included in any one of the areas (1), (4), and (7) (step S203). ).

  If the player character 100 dribbles the ball 110 with the left hand or the touched position is outside the range of the areas (1), (4), and (7), the CPU core 21 further stores the previous time in the WRAM 22. The touched position (including the position stored by default) of the touch panel 13 is within the range of any of the areas (1) to (3), and the touched position is the area (7) to (7) 9), or the touched position of the touch panel 13 previously stored in the WRAM 22 is within the range of any of the areas (7) to (9) and the position touched this time is It is determined whether it is within any one of the areas (1) to (3) (step S204).

  The position of the touch previously stored in the WRAM 22 or the position touched this time is in any of the ranges (4) to (6), or the touched position of the touch panel 13 previously stored in the WRAM 22 is the area (7 ) To (9) and the touched position is within any of the areas (7) to (9) or the touch panel 13 previously stored in the WRAM 22 is touched. When the position is within any of the areas (1) to (3) and the position touched this time is within any of the areas (1) to (3), the CPU core 21 The specific coordinates to be blended with the motion data are selected from the set specific coordinates according to the position where the touch panel 13 is touched this time (step S205).

  The CPU core 21 calculates the blend ratio of the motion data corresponding to the selected specific coordinates according to the specific coordinates and the coordinates of the position touched this time (step S206). The CPU core 21 blends the motion data corresponding to the selected specific coordinates with the calculated blend ratio, generates motion data for causing the player character 100 to dribble the ball 110, and stores the motion data in the WRAM 22 (step S207). ).

  The CPU core 21 performs frame interpolation for a predetermined number of frames until the motion data applied before the touch panel 13 is touched this time to the motion data generated according to the new touch position on the touch panel 13 (step). S208). Then, the touch-time process is terminated, and the process returns to the flowchart of FIG. Returning to the flowchart of FIG. 9, if there is no input as it is, the player character 100 is moved according to the motion data generated in step S207.

  In addition, the position where the player character 100 dribbles the ball 110 with the left hand and touched on the touch panel 13 in step S202 is included in any one of the areas (3), (6), and (9). If so, the CPU core 21 sets specific data when the player character 100 dribbles the ball 110 with the right hand and stores it in the WRAM 22. Further, the CPU core 21 selects the motion data of the joint motion corresponding to the area including the touched position previously stored in the WRAM 22 and the area including the currently touched position (step S209). Then, the process proceeds to step S212.

  In addition, the position where the player character 100 dribbles the ball 110 with the right hand in step S203 and is touched on the touch panel 13 is included in any one of the areas (1), (4), and (7). If so, the CPU core 21 sets specific data when the player character 100 dribbles the ball 110 with the left hand and stores the specific data in the WRAM 22. Further, the CPU core 21 selects the motion data of the joint motion corresponding to the area including the touched position previously stored in the WRAM 22 and the area including the currently touched position (step S210). Then, the process proceeds to step S212.

  Further, the touched position of the touch panel 13 previously stored in the WRAM 22 in step S204 is within any one of the areas (1) to (3), and the touched position is the area (7) to (9). Or the touched position of the touch panel 13 previously stored in the WRAM 22 is within any of the areas (7) to (9) and the touched position is the area ( When it is within the range of any one of 1) to (3), the CPU core 21 responds to the area including the touched position previously stored in the WRAM 22 and the area including the currently touched position. The motion data of the joint motion is selected (step S211). Then, the process proceeds to step S212.

  The processing in steps S212 to S214 is the same as the processing in steps S205 to S207. When step S214 is completed, the CPU core 21 has a predetermined number of frames from the motion data applied before the touch panel 13 is touched this time to the transition motion data selected in steps S209 to S211. Frame interpolation is performed (step S215). Thereafter, the CPU core 21 moves the player character 100 in accordance with the motion data of the linkage motion selected in Steps S209 to 211 (Step S216).

  Further, the CPU core 21 performs frame interpolation for a predetermined number of frames until the motion data of the joint motion is shifted to the motion data generated according to the new touch position on the touch panel 13 (step S217). Then, the touch-time process is terminated, and the process returns to the flowchart of FIG. Returning to the flowchart of FIG. 9, if there is no input as it is, the player character 100 is operated according to the motion data generated in step S214.

  FIG. 11 is a flowchart showing in detail the direction input processing in step S104. In the processing of this flowchart, the direction of the player character 100 and the ball 110, the direction of the route 100R, and the direction input from the direction instruction switch 14c are handled. When comparing the former direction with the latter direction, The direction input from the direction indicating switch 14c is converted in accordance with the direction from the viewpoint of the virtual camera toward the player character 100 serving as a reference point, and the input direction in the following description is the converted direction. Shall point to.

  In the direction input processing, first, the CPU core 21 determines a direction from the position of the player character 100 on the court toward the position of the ball 110 (step S301). Next, the CPU core 21 determines whether or not the direction input from the direction indicating switch 14c matches the direction of the route 100R of the player character 100 (step S302). If the input direction matches the direction of the route 100R, the player character 100 can be moved on the court as it is, and the process proceeds to step S311.

  If the input direction does not match the direction of the route 100R, it is necessary to first move the player character 100 after making the direction of the route 100R match the input direction. Here, the CPU core 21 determines whether or not the ball 110 is present in an area within a range of ± θ3 from the direction input from the direction indicating switch 14c (step S303).

  If the ball 110 does not exist in the region within the range of ± θ3, the player character 100 cannot be turned by a quick turn. In this case, the CPU core 21 stores, in the ROM 117, motion data (motion data stored in the WRAM 22 at this time or dedicated data in this case) that causes the player character 100 to dribble the ball 110. The motion data for the direction change is generated by blending with the direction change motion data that is being changed (step S304).

  The CPU core 21 changes the direction of the route 100R by a predetermined angle toward the direction input from the direction indicating switch 14c while causing the player character 100 to dribble the ball 110 using the motion data generated in step S304. (Step S305). Thereafter, the CPU core 21 determines whether or not the direction input from the direction indicating switch 14c has been canceled (step S306). If the direction input has been cancelled, the direction input process is terminated and the process returns to the flowchart of FIG.

  If the direction input has not been canceled, the CPU core 21 determines whether or not the direction of the route 100R of the player character 100 matches the direction input from the direction indicating switch 14c (step S307). If the direction of the route 100R does not yet match the input direction, the process returns to step S305, and the direction change of the player character 100 is continued. If the direction of the route 100R coincides with the input direction, the player character 100 can be moved on the court, so the process proceeds to step S310.

  If the ball 110 is present in the region within the range of ± θ3 from the input direction in step S303, the CPU core 21 immediately changes the direction of the route 100R of the player character 100 to the direction input from the direction indicating switch 14c. Conversion is performed (step S308). Thereafter, the CPU core 21 determines whether or not the direction input from the direction indicating switch 14c has been canceled (step S309). If the direction input has been cancelled, the direction input process is terminated and the process returns to the flowchart of FIG. If the direction input has not been canceled, the direction of the route 100R matches the input direction by the quick turn in step S308, and the player character 100 can be moved on the court. Proceed to processing.

  In step S310, if the player character 100 changes the direction of the route 100R while dribbling the ball 110, the direction from the position of the player character 100 to the position of the ball 110 has changed, so the CPU core 21 again determines the direction from the position of the player character 100 on the court toward the position of the ball 110. Then, the process proceeds to step S311.

  In step S311, the CPU core 21 calculates an angle θ between the direction from the position of the player character 100 determined in step S301 or S310 toward the position of the ball 110 and the direction input from the direction indicating switch 14c. Further, the CPU core 21 blends the motion data of the motion of the player character 100 dribbling the ball 110 with the motion data for movement stored in the ROM 117 to generate motion data for movement on the court ( Step S312).

  The CPU core 21 reproduces the motion data generated in step S312 at a normal cos (θ / 2) speed and moves the player character 100 on the court from the direction indicating switch 14c at a moving speed of Vcos (θ / 2). Move in the input direction (step S313).

  Thereafter, the CPU core 21 determines whether or not the direction input from the direction indicating switch 14c has been canceled (step S314). If the direction input has not been canceled, the process returns to step S313, and the player character 100 is further moved in the input direction. On the other hand, if the direction input has been cancelled, the direction input processing is terminated and the process returns to the flowchart of FIG.

  Through the processing described above, the player character 100 moves on the court formed in the virtual three-dimensional space. In addition, other characters 101 to 104 and 121 to 125 other than the player character 100 also operate on the court formed in the virtual three-dimensional space under the control of the CPU core 21. In accordance with the movements of the player character 100 and the other characters 101 to 104 and 121 to 125, the ball 110 also moves on the court formed in the virtual three-dimensional space. With these operations, the basketball game according to this embodiment proceeds.

  The progress of the game in this way is displayed as an image on the first LCD 11 and the second LCD 12, but the image displayed on the first LCD 11 and the second LCD 12 is generated as follows.

  In order to generate an image to be displayed on the first LCD 11, the CPU core 21 sets the position of the viewpoint of the virtual camera according to the action of the player character 100 or switching to the new player character 100. The CPU core 21 sets the reference point of the virtual camera at the position of the player character 100 every frame period (for example, 1/30 second), and the object (player) that is included in the range to be perspective-transformed in the virtual three-dimensional space. Each vertex of polygons constituting the character 100, the other characters 101 to 104, 121 to 125, and the ball 110) is converted into coordinates of the viewpoint coordinate system.

  The CPU core 21 sends the coordinates of each vertex converted to the viewpoint coordinate system to the first GPU 24 and outputs a drawing command to the first GPU 24. The first GPU 24 that has received the drawing command expands the image data in the first VRAM 23 so that the polygon at a position close to the viewpoint is finally drawn based on the coordinates of the viewpoint coordinate system sent from the CPU core 21. To go. Here, when developing the image data, processes such as hidden surface removal processing, shading, and texture mapping are also performed.

  The first GPU 24 sequentially reads the image data developed in the first VRAM 23, adds a synchronization signal to generate a video signal, and outputs the video signal to the first LCD 11. The first LCD 11 displays an image corresponding to the video signal output from the first GPU 24. By switching the image displayed on the first LCD 11 every frame period in this way, the player can play the player character 100 and other characters 101 to 104, 121 to 125 on the court formed in the virtual three-dimensional space. An image of a basketball game can be viewed in a three-dimensional display.

  On the other hand, in order to generate an image to be displayed on the second LCD 12, the CPU core 21 sets the position of the player character 100 to the coordinates of the center position of the second LCD 12 for each frame period, and sets the other characters 101 to 104, 1211. The coordinates on the xz plane in 125 virtual three-dimensional spaces are converted from the player character 100 to coordinates in the coordinate system in which the direction of the viewpoint of the virtual camera is set in the y-axis direction.

  The CPU core 21 sends the converted coordinates of the player character 100 and the other characters 101 to 104 and 121 to 125 to the second GPU 26 and outputs a drawing command to the second GPU 26. Receiving the drawing command, the second GPU 26 develops icons corresponding to the types of the characters 100 to 104 and 121 to 125 in the second VRAM 25 according to the coordinate positions of the characters 100 to 104 and 121 to 125.

  The second GPU 26 sequentially reads the image data developed in the second VRAM 25, adds a synchronization signal to generate a video signal, and outputs the video signal to the second LCD 12. The second LCD 12 displays an image corresponding to the video signal output from the second GPU 26. By switching the image displayed on the second LCD 12 every frame period in this way, the player can determine at which position on the court the characters 101 to 104 and 121 to 125 are centered on the player character 100. A two-dimensional image showing can be seen.

  As described above, in the basketball game according to this embodiment, when the player team does not input from the operation switch unit 14 on the offense side, the player character 100 positions on the court formed in the virtual three-dimensional space. The ball 110 will continue to be dribbling without moving. This dribbling operation is reproduced using motion data, and an image is displayed on the first LCD 11. Here, the position where the player character 100 dribbles the ball 110 can be changed by touching an arbitrary position on the touch panel 13, but if the position where the ball dribbling is changed, it is necessary to reproduce the motion of the player character 100. The motion data will be different.

  Motion data for the player character 100 to dribble the ball 110 is prepared in advance only for the specific coordinates 201 to 206 and 221 to 224 set on the touch panel 13. Here, when the player touches a position other than the specific coordinates 201 to 206 and 221 to 224 on the touch panel 13, the specific coordinates are determined according to the positional relationship between the coordinates of the touched position and the specific coordinates 201 to 206 and 221 to 224. The blend ratios of the motion data corresponding to 201 to 206 and 221 to 224 are calculated, and the motion data is blended at the blend ratios and used for reproducing the dribbling motion of the player character 100.

  As described above, the motion data corresponding to each of the specific coordinates 201 to 206 and 221 to 224 can be blended at different blend ratios depending on the touched position of the touch panel 13, so that the motion data is also changed depending on the touched position. It will be different. Thereby, a subtle difference can be expressed as a dribbling motion of the player character 100 according to the difference in the touch position of the touch panel 13, and the motion of the player character 100 similar to the motion of the real-world basketball player is reproduced. Will be able to.

  In addition, since the player character 100 is operated using different motion data depending on the touch position of the touch panel 13, from the viewpoint of the player, the player character 100 can change the ball 110 by simply changing the touch position of the touch panel 13. The position to dribble can be changed freely. Further, an instruction as to where the player character 100 should dribble the ball 110 can be input by intuitive determination as to what coordinate position the touch panel 13 touches.

  Further, when the touch panel 13 is touched while the player character 100 is moved on the court by an input from the direction indicating switch 14c, the dribbling generated according to the motion data of the player character 100 and the touched position. The motion data is blended and played back. That is, while the player character 100 moves on the court, the position where the player character 100 dribbles the ball 110 can be set by the position where the touch panel 13 is touched. For this reason, even when the player character 100 is moving on the court, the position where the ball 110 is dribbling can be changed by an input based on intuitive judgment.

  Further, even if all the motion data used for the dribbling motion of the player character 100 is ultimately different depending on the touched position of the touch panel 13, the motion that must be stored in the ROM 171 of the game cartridge 17 in advance. Only the data corresponding to the specific coordinates 201 to 206 and 221 to 224 may be used. For this reason, the storage capacity of the ROM 171 necessary for storing motion data in advance can be suppressed to a relatively small amount.

  Here, among the motion data stored in advance in the ROM 171, only two or four corresponding to specific coordinates that are deeply related to the touched position of the touch panel 13 are selected. It has become a thing. For example, when the position T shown in FIG. 4B is touched, the specific coordinates other than the specific coordinates 201, 202, 204, and 205 are far from the touched position T, and motions corresponding to them are also detected. This is because the data also becomes an operation that is contrary to the operation according to the touched position. Although there are six types of motion data stored in the ROM 117 for one hand of the player character 100 in this way and 12 types in total, only two or four pieces of motion data need to be blended. The amount of processing required to calculate the rate and blend the motion data does not have to be too large.

  The blend rate of the motion data corresponding to the selected 2 or 4 specific coordinates is calculated to be higher as the motion data corresponding to the specific coordinates closer to the touched position on the touch panel 13. For this reason, it becomes easy for the player to predict how the player character 100 moves by touching which position on the touch panel 13, and the game is not complicated. Moreover, the image displayed on the second LCD 12 below the touch panel 13 is such that the player character 100 is located in the center and the positions of the other characters 101 to 104 and 121 to 125 are also displayed. It becomes easier for the player to determine which position on the touch panel 13 should be touched according to the progress of the game.

  Also, the blend ratio of the motion data corresponding to the selected 2 or 4 specific coordinates is obtained by calculating the ratio of the distance for each coordinate of the touched position, the x coordinate and the y coordinate of the specific coordinates, and the ratio obtained for each. Are calculated by multiplying each other. For this reason, it is possible to calculate the blend rate of motion data corresponding to each specific coordinate only by relatively easy calculation such as addition / subtraction / division / division, and the processing load on the CPU core 21 for calculating the blend rate does not become excessive. .

  In addition, there are cases where the coordinates of the touched position on the touch panel 13 coincide with the specific coordinates 201 to 206 and 221 to 224. In such a case, the specific coordinates corresponding to the touched position are changed. What is necessary is just to make the player character 100 perform a dribbling motion using the corresponding motion data as it is. Therefore, it is not necessary to perform extra processing to obtain motion data used to move the player character 100, and the processing load on the CPU core 21 can be reduced.

  Since the game of this embodiment is a basketball game, the player character 100 may or may not move on the court. When the offense team and the defense team change, or when the ball 110 is passed between characters, a character different from the past may become the player character 100 that newly dribbles the ball 110. Even when the player character 100 stops moving on the court or when a different character becomes a new player character 100, the player character 100 causes the dribbling operation using the motion data corresponding to the specific coordinates 201. Can do. Since the motion data applied by default does not require motion blending, no extra processing load is applied to the CPU core 21.

  Incidentally, the dribbling motion of the ball 110 by the player character 100 includes a dribbling motion with the right hand and a dribbling motion with the left hand. Here, for example, when the player character 100 is dribbling the ball 110 with the right hand, the touch panel 13 is within the area (2), (3), (5), (6), (8), (9). If is touched, dribbling with the right hand will continue even with newly generated motion data. Only when the area (1), (4), or (7) is touched, it is changed to the left hand. When touching the touch panel 13 when the ball 110 is dribbling with the left hand, the pattern is reversed right and left.

  That is, when the area (2), (5), or (8) corresponding to the middle row on the touch panel 13 is touched, if you dribble with the right hand when touched, continue dribbling with the right hand after touching. If dribbling with the left hand when touched, the specific coordinates to be blended with the motion data are selected so that dribbling with the left hand continues even after touching. For this reason, it is possible to prevent the player character 100 from excessively changing the hand that dribbles the ball 110 or causing an unnatural replacement of the hand, thereby preventing the player from feeling uncomfortable. it can.

  Further, whether the player character 100 is dribbling the ball 110 with the right hand or the left hand when the touch panel 13 is newly touched is determined by examining the motion state of the player character 100 at the time of the touch. Instead, the determination is based on the relationship between the area including the position where the touch panel 13 was previously touched and the area including the position touched this time. For this reason, whether or not the player character 100 should change the hand that dribbles the ball 110 can also be determined with a relatively small amount of calculation.

  Further, when the player character 100 switches the hand dribbling the ball 110 from the right hand to the left hand, or from the left hand to the right hand, the motion data before touching the touch panel 13 is directly transferred to the motion data after touching the touch panel 13. is not. It is assumed that the motion data before touching the touch panel 13 is shifted to the motion data of the connection motion, and the motion data of the connection motion is further transferred to the motion data after the touch panel 13 is touched.

  When the area including the position touched last time is (1) to (3) and the area including the position touched this time is (7) to (9), or the area including the position touched last time. Are inserted even when the areas including the position touched this time are (1) to (3) in (7) to (9). Whether to insert a joint motion, including the replacement of dribbling hands, is determined by the relationship between the area that includes the position where the touch panel 13 was previously touched and the area that includes the position that was touched this time. Can be determined with a relatively small amount of calculation.

  And when the difference of the motion data applied before and after the touch panel 13 is touched is large in this way, the motion data of the connection motion is temporarily used instead of moving the motion data between the two, and the player character is temporarily used. Since 100 is operated, the player character 100 can be operated so that the player does not feel uncomfortable before and after the touch panel 13 is touched.

  By the way, although the game applied in this embodiment is a basketball game, the actions of the player character 100 other than the dribbling of the ball 110 can be instructed by an input from the operation switch unit 14. For example, the player character 100 moves or changes direction on the court formed in the virtual three-dimensional space by an input from the direction instruction switch 14c. As described above, the input from the input means other than the touch panel 13 allows the player character 100 to perform various actions other than dribbling the ball 110 for the progress of the game.

  When there is an input from the direction indicating switch 14c, the player character 100 moves in the input direction on the court while dribbling the ball 110. Considering the movement of the basketball player in the real world, the handling of the ball 110 is easier when it is in front of the body. In the basketball game according to this embodiment, the player at a speed corresponding to the angle formed by the direction from the player character 100 toward the ball 110 and the traveling direction of the player character 100 (that is, the direction input from the direction instruction switch 14c). Since the moving speed of the character 100 is changed, the player character 100 can be moved at a natural speed according to the position where the ball 110 is dribbling.

  Further, in the basketball game according to this embodiment, when there is an input from the direction instruction switch 14c, the direction in which the player character 100 is facing (the direction of the route 100R) is shifted from the traveling direction, causing the player to feel uncomfortable. First, the direction of the route 100R of the player character 100 is changed so as not to occur. Here again, considering the movement of the basketball player in the real world, if the ball is in the direction of advance, the ball 110 can be directed in the direction of advance while just moving the body upside down, If it is not, it is not necessary to flip the body to judge the ball in front.

  When the direction input from the direction indicating switch 14c is different from the direction of the route 100R of the player character 100, the position of the ball 110 is left as it is, provided that the ball is within a range of ± θ3 from the input direction. A quick turn for changing the direction of the route 100R of the player character 100 is performed. Thus, even when the player character 100 is turned in a direction corresponding to the input from the direction indicating switch 14c, the direction can be changed at a natural speed.

  As described above, the action of the player character 100 automatically changes according to the difference in the position where the ball 110 is dribbling. That is, even if there are few types of input operations that the player will perform, the player character 100 can perform natural actions according to the position where the ball 110 is dribbling. Further, the game does not become too complicated in order to make the player character 100 perform natural actions.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the blend ratio of the motion data corresponding to the specific coordinates 201 to 206 is set to the distance between the coordinate of the touched position on the touch panel 13 and the specific coordinates 201 to 206 for each of the x coordinate and y coordinate. It was supposed to be calculated based on. However, the calculation method of the blend ratio of the motion data corresponding to the specific coordinates 201 to 206 is not limited to this, and is based on the linear distance between the coordinates of the touched position on the touch panel 13 and the specific coordinates 201 to 206. It may be calculated or calculated based on the square of the straight line distance.

  In the above embodiment, the blend ratio of the motion data is calculated based on the distance between the coordinates of the touched position on the touch panel 13 and the x-coordinate and the y-coordinate between the specific coordinates 201 to 206, and the calculated blend The player character 100 is operated using the motion data blended at a rate. On the other hand, as the motion data for operating the player character 100, the motion data corresponding to the specific coordinates 201 to 206 closest to the touched position on the touch panel 13 is used as it is, and the motion data is not blended. It may be a thing.

  Here, the motion data corresponding to the specific coordinates 201 to 206 is used as it is because a position within a predetermined range (for example, a range of ± 10 for both the x coordinate and the y coordinate) from the specific coordinates 201 to 206 on the touch panel 13 is used. It may be only when it is touched. When a position outside the predetermined range is touched, the motion data is blended according to the touched position as shown in the above embodiment, and the player character 100 is operated using the blended motion data. It may be a thing.

  In the above embodiment, the motion data that defines the movement of the player character 100 is prepared in association with the specific coordinates 201 to 206 on the touch panel 13. On the other hand, motion data may be prepared in association with the areas (1) to (9) set in the area on the touch panel 13. In this case, for example, when any position within the area (1) is touched on the touch panel 13, the motion data stored in the ROM 171 in association with the area (1) is selected and the motion is selected. The player character 100 may be moved using data.

  Also, for example, if the area on the touch panel 13 is divided into areas of 5 rows and 5 columns, motion is performed only for the areas that are not included in the second and fourth rows, and the second and fourth columns. Data may be prepared. Here, if the area of the m-th row and the n-th column is expressed as an area (m, n), the areas (1, 1), (1, 3), (1, 5), (3, 1) ), (3, 3), (3, 5), (5, 1), (5, 3), and (5, 5), when touched, the touched area It is good also as what moves the player character 100 using the matched motion data as it is.

  On the other hand, when any position within the area other than this area is touched, the player character 100 may be moved using the blended motion data. For example, when a position in the range of the area (1, 2) is touched, the motion data corresponding to the area (1, 1) and the motion data corresponding to the area (1, 3) may be blended. . In this case, the blend ratio can be set to 50%. When a position within the range of the area (2, 2) is touched, the motion data corresponding to the area (1, 1), the motion data corresponding to the area (1, 3), and the area (3, 3) The motion data corresponding to 1) and the motion data corresponding to area (3, 3) may be blended. In this case, the blend ratio can be set to 25%.

  In the above embodiment, when the player character 100 moves on the court, dribble motion data that is blended with the motion data of the movement is also generated according to only the coordinates of the touched position on the touch panel 13. It was. However, depending on the moving direction of the player character 100, the dribble motion data generated only in accordance with the touched position of the touch panel 13 may cause a sense of incongruity between the moving direction and the dribbling action. .

  Therefore, the dribble motion data blended with the motion data of the movement of the player character 100 on the court, in addition to the coordinates of the touched position on the touch panel 13, The direction may be generated in accordance with the direction input from 14c. As a technique for this, for example, the coordinates of the touched position of the touch panel 13 are converted by an arithmetic expression corresponding to the moving direction of the player character 100, and the positional relationship between the coordinates converted by the arithmetic expression and the specific coordinates 201 to 206 is calculated. The dribble motion data can be generated according to the above. Whether to insert a linkage motion can also be determined according to the positional relationship between the coordinates after the return and the specific coordinates 201-206.

  As a result, when the player character 100 moves on the court, the player character 100 can dribble the ball 110 without feeling uncomfortable with the moving motion. Also, the position where the player character 100 dribbles the ball 110 can be changed by intuitive input based on the position touched by the touch panel 13.

  In the above-described embodiment, only whether the player character 100 switches the dribbling hand of the ball 110 or inserts a joint motion is determined based on the relationship between the positions where the previous touch panel 13 and the current touch panel 13 are touched. It was. Of course, the touch panel 13 of the previous time and this time is also touched to determine the difference between the direction of the route 100R of the player character 100 and the direction input from the direction indicating switch 14c and the direction of the player character 100 toward the ball 110. You may judge by the relationship between positions.

  There are eight directions that can be input from the direction indicating switch 14c, and there are other areas in the eight directions from the area (5) in the center on the touch panel 13. Therefore, all the directions are determined in units of these eight directions. It can be done as For example, it may be determined whether the direction from the player character 100 toward the ball 110 is included in one of the angle ranges obtained by dividing the direction from the viewpoint of the virtual camera into eight according to the direction toward the player character 100. Good. This facilitates the process of comparing the directions of different objects.

  In the above embodiment, when there is an input from the direction indicating switch 14c, the player character 100 sets the angle between the direction from the player character 100 toward the ball 110 and the input direction as θ, It moves in the input direction at a speed of Vcos (θ / 2). That is, the moving speed of the player character 100 changes continuously according to the magnitude of θ. On the other hand, the angle θ formed by the direction of the ball 110 from the player character 100 and the input direction is compared with a predetermined threshold value (a plurality may be present). 100 may be moved at a predetermined speed V1, and when θ is greater than this threshold, the player character 100 may be moved at a speed V2 slower than V1. That is, the moving speed of the player character 100 may be changed stepwise depending on whether θ is larger than a threshold value.

  In the above embodiment, when the direction of the route 100R of the player character 100 does not coincide with the direction input from the direction indicating switch 14c, if the player character 100 is within ± θ3 from the input direction, the player character 100 It was supposed to make 100 a quick turn on the spot. However, if the touch panel 13 is not actually touched at the time of input from the direction indicating switch 14c, the player character 100 is not quick-turned regardless of the position of the ball 110, but there is input from the direction indicating switch 14c. Sometimes, if the touch panel 13 is actually touched (however, a position within a range of ± θ3 from the input direction), the player character 100 may be turned quickly.

  In the above-described embodiment, the area on the touch panel 13 is divided into nine areas, and whether or not the connection motion is to be inserted depends on the area including the position touched first and the position touched later. It was determined according to the relationship with the included area. It is also possible to determine whether to insert a joint motion by determining the relationship between the position touched first and the position touched later.
