  The object control unit 76 controls the position and orientation of the object arranged in the game space 50 based on the first point 80 and the second point 82. For example, an “object” is an object having a longitudinal shape. Further, for example, the “object” is an object representing an object that the player character 52 uses. In the case of this embodiment, the sword object 54 corresponds to an “object” that is a control target of the object control unit 76.

  FIG. 12 is a diagram for explaining the control of the position and posture of the sword object 54 by the object control unit 76. The first point 80 (first area object 90) and the second point (second area) are illustrated. The relationship between the object 94) and the sword object 54 is shown. In the present embodiment, the object control unit 76 controls the position and posture of the sword object 54 based on the direction 84 from the first point 80 to the second point 82. More specifically, the object control unit 76 matches the direction 84 from the first point 80 to the second point 82 in the longitudinal direction of the sword object 54 (the direction 86 from the grip portion 54l to the tip portion 54a). Thus, the position and posture of the sword object 54 are controlled.

  The display control unit 78 displays the game space 50 viewed from the virtual camera 58 on the game screen (see FIGS. 4 and 5).

  Further, when the amount of movement of the sword object 54 per predetermined time is larger than the reference amount, the display control unit 78 displays the afterimage 60 of the sword object 54 on the game screen (see FIG. 5). Note that the “movement amount” is a numerical value indicating the degree of movement of the sword object 54, and can also be referred to as a change amount indicating the degree of change in the position and / or posture of the sword object 54, for example. The case where the amount of movement of the sword object 54 per predetermined time is larger than the reference amount is, for example, a case where the player character 52 swings the sword object 54 quickly, in other words, a case where the player character 52 attacks. . In this way, when the player character 52 quickly shakes the sword object 54 (when the player character 52 attacks), an afterimage 60 of the sword object 54 is displayed on the game screen.

[processing]
Processing executed on the game apparatus 10 will be described. FIG. 13 and FIG. 14 are flowcharts mainly showing processing relating to control of the sword object 54 among the processing executed by the game apparatus 10. The control unit 14 executes the processing shown in FIGS. 13 and 14 every predetermined time (in this embodiment, 1/60 second) according to the program stored in the optical disk 36. When the control unit 14 executes the processes shown in FIGS. 13 and 14, the first point control unit 72, the second point control unit 74, the object control unit 76, and the display control unit 78 are realized.

  As shown in FIG. 13, the control unit 14 updates the state of the enemy character 56 (S101). For example, the control unit 14 moves the enemy character 56 by updating the position of the enemy character 56. Further, for example, the control unit 14 causes the enemy character 56 to attack the player character 52.

  Further, the control unit 14 updates the position of the player character 52 (S102). For example, the control unit 14 moves the player character 52 based on the operation of the player. For example, the left stick 44L may be used for the movement operation of the player character 52. More specifically, when the right stick 44R is in the neutral state, the control unit 14 may move the player character 52 based on the state (tilt direction) of the left stick 44L.

  Note that operation members other than the left stick 44L and the right stick 44R may be used for the movement operation of the player character 52. For example, the direction button group 40 may be used. In this case, the control unit 14 moves the player character 52 based on the state (pressed state) of the direction button group 40.

  After the process of step S102 is completed, the control unit 14 adds 1 to the variable n (S103). The variable n is initialized to 0 at the start of the game. As will be described later, the variable n is an interval (for example, N / 60 seconds: N is an integer equal to or greater than 2) that is greater than the execution interval (for example, 1/60 seconds) of the entire process. Used to make

  The control unit 14 determines whether or not the variable n is N (for example, 4) (S104). When the variable n is N, the control unit 14 executes the processes of steps S105 to S108.

  That is, the control unit 14 acquires tilt information of the left stick 44L and the right stick 44R (S105). Then, the control unit 14 (first point control unit 72) updates the position of the first point 80 based on the tilt information of the left stick 44L (S106).

  For example, the control unit 14 updates the Xa-axis coordinate value of the first point 80 based on a numerical value indicating the inclination of the left stick 44L in the left-right direction (X-axis direction). The game data storage unit 70 stores information associating a numerical value indicating the left-right tilt of the left stick 44L with the Xa-axis coordinate value, and based on this information, the first point 80 is stored. Xa-axis coordinate values are determined.

  Further, the control unit 14 updates the Ya-axis coordinate value of the first point 80 based on a numerical value indicating the inclination of the left stick 44L in the vertical direction (Y-axis direction). The game data storage unit 70 stores information in which the numerical value indicating the vertical inclination of the left stick 44L and the Ya axis coordinate value are associated with each other, and based on this information, the first point 80 is stored. The Ya-axis coordinate value is determined.

  After the processing of step S106 is completed, the control unit 14 (second point control unit 74) updates the position of the second point 82 based on the tilt information of the right stick 44R (S107).

  For example, the control unit 14 updates the Xb-axis coordinate value of the second point 82 based on a numerical value indicating the inclination of the right stick 44R in the left-right direction (X-axis direction). The game data storage unit 70 stores information associating a numerical value indicating the tilt of the right stick 44R in the left-right direction and the Xb axis coordinate value, and based on this information, the second point 82 is stored. Xb-axis coordinate values of are determined.

  Further, the control unit 14 updates the Yb-axis coordinate value of the second point 82 based on a numerical value indicating the inclination of the right stick 44R in the vertical direction (Y-axis direction). The game data storage unit 70 stores information in which the numerical value indicating the vertical inclination of the right stick 44R and the Yb axis coordinate value are associated with each other, and based on this information, the second point 82 is stored. The Yb-axis coordinate value of is determined.

  After the processing of step S107 is completed, the control unit 14 (object control unit 76) updates the position and posture of the sword object 54 based on the positions of the first point 80 and the second point 82 (S108). . For example, the control unit 14 sets the position of the grip portion 54l of the sword object 54 based on the first point 80, and moves the position of the tip portion 54a of the sword object 54 from the first point 80 to the second point 82. The direction 84 is set based on the direction 84.

  More specifically, as shown in FIG. 12, the control unit 14 matches the position of the grip portion 54 l of the sword object 54 with the position of the first point 80. Further, the control unit 14 determines that the longitudinal direction of the sword object 54 (direction 86 from the grip portion 54l to the tip portion 54a) coincides with the direction 84 from the first point 80 to the second point 82. The position of the tip portion 54a of 54 is set. In this case, the position of the tip portion 54a of the sword object 54 is a position on a straight line extending in the direction 84 from the first point 80 to the second point 82, and the distance from the grip portion 54l is predetermined. Set to a position that is a distance.

  After the process of step S108 is completed, the control unit 14 initializes the variable n to 0 (S109). Here, the significance of the processing of steps S104 to S109 will be described. Even if the player intends to keep the tilt state of the left stick 44L and the right stick 44R constant, the tilt state of the left stick 44L and the right stick 44R often changes slightly every 1/60 seconds. For this reason, if the processing of steps S105 to 108 is also executed every 1/60 seconds, the position and posture of the sword object 54 change every 1/60 seconds. As a result, the sword object 54 is displayed as if trembling, and the player feels uncomfortable. In this regard, as in this embodiment, the execution interval of the processing of steps S105 to S108 (in other words, the update processing of the position and posture of the sword object 54) is set to the entire processing (in other words, the player character 52 and the enemy character 56. By making the interval (for example, N / 60 seconds) larger than the execution interval (for example, 1/60 seconds) of the state update process, it is possible to reduce the above-mentioned uncomfortable feeling.

  When the process of step S109 is completed, or when it is determined in step S104 that the variable n is not N, the control unit 14 updates the posture of the player character 52 as shown in FIG. 14 (S110). In step S110, the posture of the player character 52 is set based on the position of at least one of the first point 80 and the second point 82.

  For example, in step S <b> 110, first, the control unit 14 determines the position of the part of the player character 52 that holds the sword object 54. Specifically, the control unit 14 determines the position of the grip part 54 l of the sword object 54 as the position of the left hand 52 l of the player character 52. As described above, since the position of the grip portion 54l of the sword object 54 is determined based on the first point 80, the position of the left hand 52l of the player character 52 is determined based on the first point 80. It can be said.

  Further, the control unit 14 determines the position of the grip portion 54 r of the sword object 54 as the position of the right hand 52 r of the player character 52. Since the position of the grip portion 54r of the sword object 54 is determined based on the positions of the first point 80 and the second point 82, the position of the right hand 52r of the player character 52 is the first point 80 and the second point It can be said that it is determined based on the position of the point 82.

  Thereafter, the control unit 14 determines the positions of other parts of the player character 52 based on the positions of the left hand 52l and the right hand 52r of the player character 52. For example, a skeleton for controlling the position of each part of the player character 52 (in other words, the posture of the player character 52) is set inside the player character 52. In step S110, the state of the skeleton is determined based on the positions of the left hand 52l and the right hand 52r, whereby the positions of other parts of the player character 52 are determined. Note that when determining the skeleton state based on the positions of the left hand 52l and the right hand 52r, for example, a general inverse kinematics algorithm is used.

  After the process of step S110 is completed, the control unit 14 determines whether or not the sword object 54 has hit the enemy character 56 (S111). In step S111, a general collision determination algorithm is used.

  When the sword object 54 hits the enemy character 56, the control unit 14 updates the state of the enemy character 56 (S112). For example, the enemy character 56 is updated to a state in which it has been exterminated.

  When the process of step S112 is completed, or when it is determined in step S111 that the sword object 54 does not hit the enemy character 56, the control unit 14 (display control unit 78) represents the game space 50 viewed from the virtual camera 58. A visual field image is generated on the VRAM (S113).

  Thereafter, the control unit 14 (display control unit 78) determines whether or not the movement amount of the sword object 54 is larger than the reference amount (S114). In this step S114, for example, the amount of change in the position of the tip portion 54a of the sword object 54 is used as the “movement amount”. Note that the change amount of the position of the second point 82 may be used as the “movement amount”.

  When the movement amount of the sword object 54 is larger than the reference amount, the control unit 14 (display control unit 78) draws the afterimage 60 of the sword object 54 on the visual field image generated on the VRAM (S115). For example, the history of the position of the sword object 54 is stored in the main memory 16, and the drawing position of the afterimage 60 of the sword object 54 is determined based on the history of the position of the sword object 54.

  The image generated on the VRAM by the processes in steps S113 to S115 is displayed on the display unit 32 as a game screen. This process is complete | finished above.

[Summary]
In the game apparatus 10 described above, the first point 80 and the second point 82 that are the basis of control of the sword object 54 are set in the game space 50. The position of the first point 80 is controlled based on the tilt state of the left stick 44L, and the position of the second point 82 is controlled based on the tilt state of the right stick 44R. The position and posture of the sword object 54 are controlled based on the positions of the first point 80 and the second point 82.

  According to the game apparatus 10, the position and posture of the sword object 54 change finely based on the tilt state of the left stick 44L and the right stick 44R. Therefore, according to the game apparatus 10, it becomes possible for the player to give detailed instructions on how to hold and swing the sword object 54 using the left stick 44L and the right stick 44R. That is, according to the game apparatus 10, it is possible to improve the operability of the operation related to the sword object 54 possessed by the player character 52.

  By the way, as another method for making it possible to instruct in detail how to hold and swing the sword object 54, a method using a controller incorporating an acceleration sensor or the like is also conceivable. However, in this case, the controller 30 needs to incorporate an acceleration sensor or the like. In this regard, according to the present embodiment, the controller 30 does not need to incorporate an acceleration sensor or the like.

  In the game apparatus 10, the first area object 90 is arranged in the game space 50, and the area where the first point 80 can move is limited to the surface 92 of the first area object 90. Similarly, the second area object 94 is arranged in the game space 50, and the area where the second point 82 can move is limited to the surface 96 of the second area object 94. Since the position and posture of the sword object 54 change based on the positions of the first point 80 and the second point 82, the sword object 54 can be held and swung by the first area object. It changes depending on the shape and size of 90 and the second area object 94 and the positional relationship with the player character 52.

  According to the game device 10, in game development, a person who creates the shape of an object placed in the game space 50 can be involved in determining how to hold and swing the sword object 54 that the player character 52 can hold. become.

[Modification]
The present invention is not limited to the embodiment described above.

  (1) For example, the object control unit 76 may correct the movement of the sword object 54 when the player character 52 swings the sword object 54 (that is, when the player character 52 attacks).

  When the player character 52 swings the sword object 54, if the sword object 54 is moved according to the operation of the left stick 44L and the right stick 44R, the movement of the sword object 54 may become unnatural. In this regard, the movement of the sword object 54 may be prevented from becoming unnatural by the following description.

  In this case, the object control unit 76 determines whether or not the amount of movement of the sword object 54 per predetermined time is larger than the reference amount. In other words, the object control unit 76 determines whether or not the player character 52 is quickly swinging the sword object 54 (whether or not the player character 52 is attacking). This determination is performed in the same manner as in step S114 of FIG.

  When the amount of movement of the sword object 54 per predetermined time is larger than the reference amount, the object control unit 76 acquires the change direction of the position and posture of the sword object 54 as a basic direction. Then, the object control unit 76 corrects the change direction of the position and posture of the sword object 54 after the basic direction is acquired based on the basic direction.

  FIG. 15 is a diagram for explaining the correction of the movement of the sword object 54. For example, even when the player performs an operation with the intention of swinging the sword object 54 so that the tip 54a of the sword object 54 draws a linear trajectory such as P1 to P5 shown in FIG. Actually, there is a case where the distal end portion 54a performs an operation for drawing a curved trajectory such as P1, P2, Q3, Q4, and Q5 shown in FIG. This is likely to occur when the player operates the left stick 44L and the right stick 44R using the left and right thumbs. In such a case, the player may feel that the movement of the sword object 54 is unnatural.

  Therefore, when the movement amount when the position of the tip portion 54a of the sword object 54 changes from P1 to P2 is larger than the reference amount, the object control unit 76 acquires the direction from P1 to P2 as the basic direction. Thereafter, the object control unit 76 corrects the position of the distal end portion 54a of the sword object 54 to the position of the leg of the perpendicular line that is lowered from the original position of the distal end portion 54a on the straight line 98 extended in the basic direction. For example, when the original position of the tip portion 54a of the sword object 54 is Q3, the object control unit 76 perpendiculars the position of the tip portion 54a of the sword object 54 on the straight line 98 from the original position (Q3). To the position of the foot (P3). In this way, it is possible to prevent the player from feeling that the movement of the sword object 54 is unnatural.

  Here, an example in which the position of the tip portion 54a of the sword object 54 is corrected has been described, but the position of the second point 82 may be corrected instead of the tip portion 54a of the sword object 54.

  Further, the correction of the movement of the sword object 54 may be terminated when a predetermined time has elapsed since the sword object 54 was started to swing for an attack. Alternatively, the correction of the movement of the sword object 54 may be ended when the movement amount of the sword object 54 becomes equal to or less than the reference amount.

  (2) For example, the first point 80 may be associated with a portion other than the grip portion 54l of the sword object 54. For example, the first point 80 may be associated with the grip portion 54 r of the sword object 54. In this case, the shape and size of the first area object 90 (that is, the first area) and the positional relationship with the player character 52 are set in consideration of the area where the right hand 52r of the player character 52 reaches.

  (3) For example, the second point 82 may be associated with a portion other than the tip portion 54 a of the sword object 54. For example, the second point 82 may be associated with the grip portion 54 r of the sword object 54. In this case, the shape and size of the second area object 94 (that is, the second area) and the positional relationship with the player character 52 are set in consideration of the area where the right hand 52r of the player character 52 can reach. Also in this case, the object control unit 76 controls the posture of the sword object 54 so that the longitudinal direction of the sword object 54 coincides with the direction 84 from the first point 80 to the second point 82.

  Note that the second point 82 is greater when the distance from the first point 80 to the second point 82 is longer than when the distance from the first point 80 to the second point 82 is shorter. Since the movable region (second region) is widened, it is easy to make adjustments for smooth movement of the sword object 54 (tip portion 54a).

  (4) For example, another operation member may be used instead of the left stick 44L. For example, the direction button group 40 may be used. In this case, the first point control unit 72 moves the first point 80 based on the pressed state of the direction button group 40. In this case, a pressing force applied to the left button 40L, the right button 40R, the up button 40U, and the down button 40D is used instead of the left stick 44L tilting in the left-right direction and the up-down direction.

  The controller 30 may include a cross button having a cross shape instead of the direction button group 40. For example, in the cross button, an upper pressing part corresponding to the upper direction, a lower pressing part corresponding to the lower direction, a left pressing part corresponding to the left direction, and a right pressing part corresponding to the right direction are integrally formed. It is a formed button.

  Further, instead of the direction button group 40, the buttons 42A, 42B, 42X, and 42Y may be used instead of the left stick 44L. In this case, it may be considered that the button 42Y corresponds to the upward button 40U and the button 42A corresponds to the downward button 40D. Further, it may be considered that the button 42X corresponds to the left direction button 40L and the button 42B corresponds to the right direction button 40R.

  Similar to the left stick 44L, another operation member may be used instead of the right stick 44R.

  (5) For example, the player character 52 may have a weapon object other than the sword object 54. When the player character 52 changes a plurality of types of weapon objects, an area where the first point 80 can move (first area) and an area where the second point 82 can move for each weapon object. At least one of (second region) may be changed. That is, at least one of the shape and size of the first area object 90 and / or the second area object 94 or the positional relationship with the player character 52 may be changed based on the type of weapon object. In this case, data relating to at least one of the shape and size of the first area object 90 and / or the second area object 94 or the positional relationship with the player character 52 is stored for each type of weapon object. 70 may be stored. In this way, it becomes possible to change the manner of holding and swinging the weapon object for each type of weapon object.

  (6) For example, when the player character 52 is selected from a plurality of types of game characters, for each game character, an area in which the first point 80 is movable (first area), and a second You may make it change at least one of the area | region (2nd area | region) to which the point 82 can move. That is, at least one of the shape and size of the first area object 90 and / or the second area object 94 or the positional relationship with the player character 52 may be changed based on the type of the game character. In this case, data relating to at least one of the shape and size of the first area object 90 and / or the second area object 94 or the positional relationship with the player character 52 is stored for each game character type. 70 may be stored. This makes it possible to change the way the sword object 54 is held and how to swing for each type of game character.

  (7) For example, the game space may be a two-dimensional game space in which the position and posture of the player character, sword, and enemy character are managed by two coordinate elements.

  (8) For example, the present invention can be applied to a game in which the player character 52 has an object other than a weapon object. The present invention can also be applied to games other than action games. For example, the present invention can be applied to a baseball game in which a player character has a bat object. In this case, it becomes possible for the player to instruct in detail how to hold and swing the bat object. Further, for example, the present invention can be applied to a game in which a game character runs through all. In this case, it becomes possible for the player to instruct in detail how to row the oar.

  Note that the object to be controlled by the object control unit 76 may not be an object having a longitudinal shape, and may not be an object held by a game character. For example, the present invention can also be applied to a game in which the player finely adjusts the posture of an object floating in the game space using the left stick 44L and the right stick 44R.
