[Game Overview]
In this embodiment, a so-called battle fighting game is executed in which a player character is operated to play against an enemy character. FIG. 2 is a diagram illustrating a game play state of the present embodiment in the game system 1. According to the figure, a game screen on which the player character 20 with the weapon 30 and the enemy character 40 appear is displayed on the display 1202.

  FIG. 3 is an enlarged view of the weapon 30 that the player character 20 has. According to the figure, the weapon 30 is a so-called “belly sword”, and is composed of a sword pattern 31, a sword blade 32, and a weight 33 attached to the sword tip of the sword blade 32. The blade 32 has a joint structure in which a plurality of blades are connected in a bellows shape, and each blade joint corresponding to a joint has a rotational angle limit. Is controlled within a certain angle. Accordingly, the blade 32 moves while bending. The sword pattern 31 is held and fixed by the right hand of the player character 20. That is, it can be said that the weight 33 which is a moving body is connected to the right hand of the player character 20 by the connecting body composed of the sword pattern 31 and the sword body 32.

  The player 10 faces the display 1202 and holds the game controller 1300 with the right hand. That is, as shown in FIG. 4, the thumb is held on the operation surface 1310 side so that the operation button 1302 or the cross key 1304 can be operated with the thumb, and the tip portion 1312 is held toward the display 1202. Then, the player 10 performs an operation of swinging the game controller 1300 (swing operation) as a game operation. Then, the player character 20 swings the weapon 30 in response to the swing operation, and when the weapon 30 collides with the enemy character 40, predetermined damage is given to the enemy character 40.

[principle]
In the present embodiment, there are two types of operation modes, “activation mode” and “follow-up mode”. In any operation mode, the player character 20 is controlled based on the acceleration α detected by the acceleration sensor 1306 of the game controller 1300, but the control content is different. Therefore, even if the same swing operation is performed, the operation of the player character 20 differs depending on the operation mode. The selection of the operation mode is realized by pressing the operation button 1302. That is, the state where the operation button 1302 is pressed is “follow mode”, and the state where the operation button 1302 is not pressed (released state) is “activation mode”.

(A) Activation Mode In the “activation mode”, a plurality of types of swing operations are determined in advance. When any of the swing operations is performed, the player character 20 performs a weapon 30 determined in advance according to the swing operation performed. This is a mode in which the swinging operation is started. That is, using a predetermined swing operation as an activation condition, when this condition is satisfied, a predetermined swinging operation is activated (started). Specifically, in the activation mode, it is determined whether any of “right swing”, “left swing”, and “down” is performed as the swing operation.

  FIG. 5 is a diagram for explaining the “right swing operation”. FIG. 4A is a front view of the player 10 performing a right swing operation. As shown in FIG. 5A, the right swing operation is an operation in which the player 10 moves the right hand holding the game controller 1300 horizontally from the right position of the body toward the front. The operation direction of the swing operation is “right”.

  At this time, the player 10 keeps the game controller 1300 in the posture shown in FIG. FIG. 6B is a side view of the game controller 1300 viewed from the tip end portion 1312 side. According to FIG. 5B, in the right swing operation, the operation surface 1310 of the game controller 1300 is kept substantially vertical, and the operation surface 1310 is operated in the forward direction. That is, the operation surface 1310 is in a state facing the operation direction (swing direction) of the swing operation.

  Then, the player character 20 performs an action of swinging the weapon 30 as shown in FIG. FIG. 4C shows an example of the operation of the player character 20 in the game space. According to FIG. 5C, the player character 20 performs an action of swinging (feeding out) the weapon 30 horizontally in a direction coinciding with the swing direction, that is, from the right to the left front direction. This swinging direction is “right”.

  FIG. 6 is a diagram for explaining the “left swing operation”. FIG. 4A is a front view of the player 10 performing a left swing operation. As shown in FIG. 5A, the left swing operation is an operation in which the player 10 moves the right hand holding the game controller 1300 horizontally from the left position of the body toward the front. This swing direction is “left”.

  At this time, the player 10 keeps the game controller 1300 in the posture shown in FIG. FIG. 6B is a side view of the game controller 1300 viewed from the tip end portion 1312 side. According to FIG. 5B, in the left swing operation, the operation surface 1310 of the game controller 1300 is kept substantially vertical and the operation surface 1310 is operated backward. That is, the operation surface 1310 is in a state opposite to the swing direction.

  Then, the player character 20 performs an action of swinging the weapon 30 as shown in FIG. FIG. 4C shows an example of the operation of the player character 20 in the game space. According to FIG. 5C, the player character 20 performs an operation of swinging (feeding out) the weapon 30 substantially horizontally from the left in the direction matching the swing direction, that is, from the left to the front right. This swinging direction is “left”.

  FIG. 7 is a diagram for explaining the “down swing operation”. FIG. 4A is a front view of the player 10 performing a swing-down operation. As shown in FIG. 5A, the swing-down operation is an operation in which the player 10 moves the right hand holding the game controller 1300 from the position above the body toward the front. This swing direction is referred to as “down”.

  At this time, the player 10 keeps the game controller 1300 in the posture shown in FIG. FIG. 6B is a side view of the game controller 1300 viewed from the tip end portion 1312 side. According to FIG. 5B, in the swing-down operation, the operation surface 1310 of the game controller 1300 is operated upward. That is, the operation surface 1310 is in a state opposite to the swing direction.

  Then, the player character 20 performs an action of swinging the weapon 30 as shown in FIG. FIG. 4C shows an example of the operation of the player character 20 in the game space. According to FIG. 5C, the player character 20 performs an action of swinging (feeding out) the weapon 30 in a direction coinciding with the swing direction, that is, from the top to the front-down direction. This swing direction is defined as “down”.

  The swinging motion of the weapon 30 by the player character 20 in the activation mode is controlled as follows. That is, when the swing operation by the player 10 is performed, the right arm 21 of the player character 20 is controlled so that the weapon 30 is swung in the performed operation direction. Further, the movement trajectory of the weight 33 of the weapon 30 is set according to the swing direction made, and the weight 33 is controlled so as to move along the set movement trajectory.

(A-1) Determination of Swing Direction The swing operation performed by the player is determined based on the accelerations αx, αy, αz detected by the acceleration sensor 1306 of the game controller 1300. Since the acceleration sensor 1306 always detects gravitational acceleration, a combined value of the gravity G and the movement acceleration F generated by the movement of the game controller 1300 by the swing operation is detected as the acceleration α. Gravity G is always generated vertically downward, and its magnitude is “1.0 G”. Further, the movement acceleration F is generated in the direction opposite to the swing direction, and the magnitude thereof is sufficiently larger than the gravity G and is “several G to about several tens of G”.

  First, the start of a swing operation, that is, the start of swinging of the game controller 1300 is detected. Specifically, it is determined that the swing operation has been started when the acceleration αz exceeds a predetermined threshold (specifically, a value larger than the magnitude of the gravity G. For example, “1.1 G”). This is because when the game controller 1300 is swung, a large centrifugal force is generated in the longitudinal direction, and this centrifugal force is detected as an acceleration αz in the Zc-axis direction that coincides with the longitudinal direction.

  When it is determined that the swing operation is started, the accelerations αx, αy, and αz detected by the acceleration sensor 1306 are sampled (captured) for a predetermined time at predetermined time intervals (for example, frame time intervals). . Next, for each of the sampled acceleration components αx, αy, αz, average accelerations αxa, αya, αza, which are average values for each sampling, are calculated. Then, the operation direction of the swing operation is determined based on the average accelerations αxa, αya, αza.

  Here, the accelerations αx, αy, and αz detected by the acceleration sensor 1306 when the swing operation in each direction is performed will be briefly described. For the sake of simplicity, the acceleration component αz in the Z-axis direction will be omitted from the description.

  FIG. 8 shows a side view of the game controller 1300 viewed from the rear end 1314 side and accelerations αx and αy detected by the acceleration sensor 1306 in the case of “right swing operation”. In the right swing operation, the state in which the operation surface 1310 is kept vertical is an ideal state. However, as will be described later with reference to FIG. The right swing operation is detected even in a tilted state.

  As shown in FIG. 8, in the “ideal” state where the operation surface 1310 of the game controller 1300 is vertical, the direction of gravity G coincides with the negative direction of the Xc axis, and the direction of the detected movement acceleration F is the negative direction of the Yc axis. Matches. That is, in the “ideal” state, the acceleration αx is detected as “−G” in the negative direction with the magnitude of gravity G. However, in a state where the operation surface 1310 is “tilted to the left” with respect to the vertical direction, the acceleration αx is the sum of the Xc component “−Fx” of the moving acceleration F and the Xc component “− | Gx |” of the gravity G. “− | Fx | − | Gx |” is detected. Further, in a state where the operation surface 1310 is “inclined to the right” with respect to the vertical direction, the acceleration αx is expressed by the Fc component “+ | Fx |” of the movement acceleration F and the Xc component “− | Gx |” of the gravity G. "| Fx |-| Gx |" which is the sum of the two is detected.

  Here, the magnitudes of the movement acceleration Fx and the gravity Gx vary depending on the degree of inclination of the operation surface 1310. That is, when the inclination angle of the operation surface 1310 with respect to the vertical direction is “θ”, the movement acceleration Fx is given by Fx = F · sin θ, and the gravity Gx is given by Gx = G · cos θ. That is, the moving acceleration Fx gradually decreases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. On the other hand, the gravitational acceleration Gx gradually decreases from “−G” as the inclination of the operation surface 1310 to the left and right increases. Accordingly, the detected acceleration αx is “− | G |” in the “ideal” state, and gradually decreases as the tilt angle θ toward the left increases, and increases as the tilt angle θ toward the right increases. Gradually grows. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αx is a value close to negative “− | G |” in the magnitude of the gravity G, that is, “−1”. About 0.0G "is detected.

  Further, in the “ideal” state, the magnitude “− | F |” of the movement acceleration F is detected as the acceleration αy. However, in the state where the operation surface 1310 is “tilted to the left”, the acceleration αy is the sum of the Yc component “− | Fy |” of the moving acceleration F and the Yc component “+ | Gy |” of the gravity G “ − | Fy | + | Gy | ”is detected. In the state where the operation surface 1310 is “tilted to the right”, the acceleration αy is the sum of the Yc component “− | Yc |” of the moving acceleration F and the Yc component “− | Gy |” of the gravity G “ − | Fy | − | Gy | ”is detected.

  Here, the magnitudes of the movement acceleration Fy and the gravity Gy differ depending on the degree of inclination of the operation surface 1310. That is, when the inclination angle of the operation surface 1310 with respect to the vertical direction is “θ”, the movement acceleration Fy is given by Fy = F · cos θ, and the gravity Gy is given by Gy = G · sin θ. That is, the movement acceleration αy gradually increases from “− | F |” as the left and right inclination of the operation surface 1310 increases. On the other hand, gravity Gx gradually increases from “0” as the leftward inclination of operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. Accordingly, the detected acceleration αy is “− | F |” in the “ideal” state, but gradually increases as the inclination angle θ to the left and right increases. However, the ascending curve is not symmetrical. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αy is a value close to negative “− | F |” in the magnitude of the moving acceleration F, that is, “−”. “Several tens of G to several G” is detected.

  FIG. 9 shows a side view of the game controller 1300 viewed from the rear end 1314 side and accelerations αx and αy detected by the acceleration sensor 1306 when the “left swing operation” is performed. In the left swing operation, the state where the operation surface 1310 is kept vertical is ideal as in the right swing operation, but the operation surface 1310 is inclined with respect to the vertical direction according to the conditions determined by the direction determination table 331 in FIG. Even in this state, the left swing operation is detected.

  As shown in FIG. 9, in the “ideal” state where the operation surface 1310 is vertical, the direction of gravity G coincides with the negative direction of the Xc axis, and the direction of detected acceleration F coincides with the positive direction of Yc. That is, in the “ideal” state, the acceleration αx is detected as “− | G |” in the negative direction with the magnitude of gravity G. However, in the state where the operation surface 1310 is “left tilted” with respect to the vertical direction, the acceleration αx is expressed as the Xc component “+ | Fx |” of the moving acceleration F and the Yc component “− | Gx |” of the gravity G. "| Fx |-| Gx |" which is the sum of the two is detected. When the operation surface 1310 is “slightly inclined to the right” with respect to the vertical direction, the acceleration αx includes the Xc component “− | Fx |” of the movement acceleration F and the Xc component “− | Gx |” of the gravity G. Is detected as “− | Fx | − | Gx |”.

  Here, the magnitudes of the movement acceleration Fx and the gravity Gx vary depending on the inclination angle θ of the operation surface 1310 with respect to the vertical direction. That is, the movement acceleration Fx is given by Fx = F · sin θ, and the gravity Gx is given by Gx = G · cos θ. That is, the movement acceleration Fx gradually increases from “0” as the leftward tilt angle θ of the operation surface 1310 increases, and gradually decreases from “0” as the rightward tilt increases. On the other hand, the gravity Gx gradually increases from “− | G |” as the inclination of the operation surface 1310 in the left-right direction increases. Therefore, the value of the detected acceleration αx is “− | G |” in the “ideal” state, but gradually increases as the tilt angle θ toward the left increases, and the tilt angle θ toward the right increases. It gets smaller gradually as it gets larger. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αx is a value close to negative “− | G |” in the magnitude of gravity G, that is, “−1”. About 0.0G "is detected.

  In the “ideal” state, the magnitude “F” of the movement acceleration F is detected as the acceleration αy. However, in the state where the operation surface 1310 is “tilted to the left”, the acceleration αy is the sum of the Yc component “+ | Fy |” of the moving acceleration F and the Yc component “+ | Gy |” of the gravity G “ Fy + Gy ”is detected. In the state where the operation surface 1310 is “inclined to the right”, the acceleration αy is the sum of the Yc component “Fy” of the moving acceleration F and the Yc component “− | Gy |” of the gravity G “| Fy |”. − | Gy | ”is detected.

  Here, the magnitudes of the movement acceleration Fy and the gravity Gy vary depending on the inclination angle θ of the operation surface 1310 with respect to the vertical direction. That is, the movement acceleration Fy is given by Fy = F · cos θ, and the gravity Gy is given by Gy = G · sin θ. That is, the movement acceleration Fy gradually decreases from “F” as the inclination of the operation surface 1310 in the left-right direction increases. On the other hand, the gravity Gy gradually increases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. Therefore, the detected acceleration αy is “| F |” in the “ideal” state, and gradually decreases as the inclination angle θ in the left-right direction increases. However, the descending curve is not symmetrical. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αy is a value close to the magnitude “| F |” of the movement acceleration F, that is, “several G to several dozens”. "About G" is detected.

  FIG. 10 shows a side view of the game controller 1300 viewed from the rear end 1314 side and accelerations αx and αy detected by the acceleration sensor 1306 in the case of the “down swing operation”. In the swing-down operation, the state where the operation surface 1310 is directed upward and the horizontal direction (short direction) of the game controller 1300 is horizontal is an ideal state, but depending on the conditions determined by the direction determination table 331 in FIG. The swing-down operation is detected even in a state in which the direction (longitudinal direction) is tilted to the left and right about the axis center.

  As shown in FIG. 10, in the “ideal” state in which the left and right direction of the game controller 1300 is horizontal, the direction of gravity G coincides with the negative direction of the Yc axis, and the direction of detected movement acceleration F is the positive direction of the Yc axis. Match. That is, in the “ideal” state, the acceleration αx is detected as “0”. However, in a state in which the left and right direction of the game controller 1300 is “tilted to the left” with respect to the horizontal direction, the acceleration αx includes the Xc component “| Fx |” of the movement acceleration F and the Xc component “− | Gx | "| Fx |-| Gx |" which is the sum of " In the state of “tilting right”, the acceleration αx is “− | Fx | +” which is the sum of the Xc component “− | Fx |” of the moving acceleration F and the Xc component “| Gx |” of the gravity G. | Gx | "is detected.

  Here, the movement acceleration Fx and the gravity Gx differ depending on the degree of inclination of the game controller 1300 in the left-right direction. That is, when the horizontal inclination angle with respect to the horizontal direction is “φ”, the movement acceleration Fx is given by Fx = F · sinφ, and the gravity Gx is given by Gx = G · sinφ. That is, the movement acceleration Fx gradually increases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. On the other hand, the gravity Gx gradually increases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. However, the magnitude “F” of the movement acceleration F is sufficiently larger than the magnitude “G” of the gravity G. Therefore, the detected acceleration αx is “0” in the “ideal” state, but gradually increases as the left inclination angle φ increases, and gradually decreases as the right inclination angle φ increases. Become. That is, if the inclination angle φ is small, that is, if the left and right direction of the game controller 1300 is kept substantially horizontal, a value of “0” is detected for the acceleration αx.

  In the “ideal” state, the acceleration αy is the sum of the Yc component “+ | F |” of the moving acceleration F and the Yc component “− | G |” of the gravity G “| F | − | G”. | "Is detected. However, in both the “tilt left” state and the “tilt right” state, the acceleration αy includes the Yc component “+ | Fy |” of the moving acceleration F and the Yc component “− | Gy” of the gravity G. “| Fy | − | Gy |” which is the sum of “|” is detected.

  Here, the movement acceleration Fy and the gravity Gy differ depending on the inclination angle φ. That is, the movement acceleration Fy is given by Fy = F · cos φ, and the gravity Gy is given by Gy = G · cos φ. That is, the movement acceleration Fx gradually decreases from “F” as the inclination of the operation surface 1310 in the left-right direction increases. On the other hand, the gravity Gx gradually increases from “− | G |” as the inclination of the operation surface 1310 in the left-right direction increases. Therefore, the detected acceleration αy is “| F | − | G |” in the “ideal” state, but gradually decreases as the tilt angle φ to the left and right increases. In other words, if the tilt angle φ is small and the left and right direction of the game controller 1300 is kept almost horizontal, the acceleration αy is a value close to “| F | − | G |”, that is, “ten to several G to several A value of “about G” is detected.

  By the way, when performing a swing-down operation as a swing operation, the player 10 raises the right hand holding the game controller 1300 upward and then swings the right hand down. In addition, the sampling of the detected acceleration α is started after it is determined that the value of the acceleration αz in the longitudinal direction of the game controller 1300 has exceeded a predetermined threshold value. That is, there is a possibility that the sampled accelerations αx, αy, αz are values of a period during which the swing-up operation, which is a stage before the swing-down operation intended by the player, is performed.

  FIG. 11 shows a side view of the game controller 1300 viewed from the rear end 1314 and accelerations αx and αy detected by the acceleration sensor 1306 in the case of this “swinging up operation”. In the swing-up operation, as in the swing-down operation, the state where the left-right direction of the game controller 1300 is kept horizontal is an ideal state, but even if the left-right direction is slightly inclined with respect to the horizontal direction, Detection is possible according to the conditions defined in the direction determination table 331 in FIG.

  As shown in FIG. 11, in the “ideal” state where the left and right directions of the game controller 1300 are horizontal, the directions of the detected movement acceleration F and gravity G coincide with the Yc axis negative direction. That is, in the “ideal” state, the acceleration αx is detected as “0”. However, in a state where the left-right direction is “tilted to the left” with respect to the horizontal direction, the acceleration αx is an Xc component “− | Fx |” of the moving acceleration F and an Xc component “− | Gx |” of the gravity G. The sum “− | Fx | − | Gx |” is detected. In the state where the left-right direction is “inclined to the right” with respect to the horizontal direction, the acceleration αx is an Xc component “+ | Fx |” of the moving acceleration F and an Xc component “+ | Gx |” of the gravity G. The sum “| Fx | + | Gx |” is detected.

  Here, the magnitudes of the movement acceleration Fx and the gravity Gx differ depending on the inclination angle φ of the game controller 1300 with respect to the horizontal direction in the left-right direction. That is, the movement acceleration Fx is given by Fx = F · sinφ, and the gravity Gx is given by Gx = G · sinφ. That is, both the movement acceleration Fx and the gravity Gx gradually decrease from “0” as the leftward inclination of the operation surface 1310 increases, and gradually increase from “0” as the rightward inclination increases. Become. Therefore, the detected acceleration αx is “0” in the “ideal” state, but gradually decreases as the tilt angle φ toward the left increases, and gradually increases as the tilt angle φ toward the right increases. growing. That is, if the inclination angle φ is small, that is, if the left and right direction of the game controller 1300 is kept substantially horizontal, a value of “0” is detected for the acceleration αx.

  In the “ideal” state, the acceleration αy is “− | F | − | G, which is the sum of the magnitude“ − | F | ”of the movement acceleration F and the magnitude“ − | G | ”of the gravity G. | "Is detected. However, in the state where the left-right direction of the game controller 1300 is “tilt left” and “tilt right”, the acceleration αy is the Yc component “− | Fy |” of the movement acceleration F and the gravity G "-| Fy |-| Gy |" which is the sum of Yc component "-| Gy |"

  Here, the magnitudes of the movement acceleration Fy and the gravity Gy differ depending on the inclination angle φ. That is, the movement acceleration Fy is given by Fy = F · cos φ, and the gravity Gy is given by Gx = G · cos φ. That is, the movement acceleration Fy gradually increases from “F” as the inclination of the operation surface 1310 in the left-right direction increases. Also, the gravity Gy gradually increases from “G” as the inclination of the operation surface 1310 in the left-right direction increases. Therefore, the detected acceleration αy is “− | F | − | G |” in the “ideal” state, but gradually increases as the tilt angle φ to the left and right increases. In other words, if the inclination angle φ is small, that is, if the left and right direction of the game controller 1300 is kept almost horizontal, the acceleration αy is a value close to “− | F | − | G |”, that is, “−ten”. A value of “G˜about several G” is detected.

  As described above, the combinations of the values of the accelerations αx and αy detected by the acceleration sensor 1306 differ depending on the difference in the swing direction. For this reason, the swing direction made by the player is determined based on the combination of the values of the average accelerations αxa, αya calculated from the sampled accelerations αx, αy, αz.

(A-2) Control of the swinging motion of the weapon 30 of the player character 20 When the swing direction is determined, the swinging direction of the weapon 30 by the player character 20 is determined. The swing direction of the weapon 30 is one of three types, “right”, “left”, and “down”, and the swing direction is determined in a direction that matches the determined swing direction. That is, if the swing operation is “right swing”, the swing direction is “right”, and if the swing operation is “left swing”, the swing direction is “left”. If the swing operation is “down” or “up”, the swing direction is “down”.

  When the turning direction of the weapon 30 is determined, the movement trajectory of the weight 33 of the weapon 30 is then determined. That is, when the swinging direction is “right”, a curved trajectory on the horizontal plane that passes forward from the right position of the player character 20 to the left position is set as the movement trajectory. When the swinging direction is “left”, a curved trajectory on the horizontal plane that passes from the left position of the player character 20 to the right position through the front is set as the movement trajectory. When the swing direction is “down”, a curved trajectory on the vertical plane extending from the position above the player character 20 to the front lower direction is set as the movement trajectory.

  Specifically, as shown in FIG. 12A, first, a plurality of reference control points Q corresponding to the turning direction are set in the game space. These reference control points Q are set on the reference trajectory serving as a reference for the moving trajectory determined for each swinging direction, and the reference trajectory is calculated by performing interpolation calculation on these reference control points Q. It has become. This figure shows a case where the swing direction is “right”. In this case, as the reference trajectory TR1, a curve on the horizontal plane from the start point Q1 defined at the right position of the player character 20 to the end point Q8 defined at the left position passing through the front of the player character 20 is shown. A plurality of reference control points Q are set along the reference trajectory TR1.

Then, as shown in FIG. 2B, the trajectory control point R is set based on these reference control points Q. According to the figure, the trajectory control point R is on a straight line connecting the position Pp of the player character 20 and each reference control point Q and the distance r from the position Pp satisfies the following expression (1). Is set.
r = (αm / αp) × s (1)
Here, “αp” is a predetermined reference acceleration. “Αm” is the maximum value (maximum acceleration) of the sampled acceleration α (= √ (αx ² + αy ² + αz ² )). “S” is a distance from the position Pp to the reference control point Q, and is determined in advance.

  That is, with reference to the position Pp of the player character 20, the position of the reference control point Q is changed in accordance with the ratio between the detected maximum acceleration αm and a predetermined reference acceleration αp, whereby the trajectory control point R is changed. Is set. That is, the trajectory control point R is set at a position farther from the player character position Pp as the maximum acceleration αm is larger. However, the start point R1 and the end point R8 are fixed. Then, by performing a predetermined interpolation calculation (for example, spline interpolation) based on these trajectory control points R, a moving trajectory TR2 from the start point R1 through the trajectory control points R to the end point R8 is set.

  Further, as shown in FIG. 13A, these trajectory control points R are corrected based on the positional relationship with the enemy character 40. According to the figure, for each trajectory control point R, it is determined whether or not the enemy character 40 is positioned within a predetermined collision determination area JA. If the enemy character 40 is positioned, the position of the enemy character 40 is determined. The trajectory control point R is changed (corrected). The collision determination area JA is an area in which the weight 33 of the weapon 30 is caused to collide with the enemy character 40, and is set here as an area inside the sphere centered on the trajectory control point R. This figure shows a case where an enemy character is located in the collision determination area JA of the trajectory control point R4, and the trajectory control point R4 is changed to the position Pe of the enemy character.

  Then, as shown in FIG. 5B, by performing an interpolation calculation between the respective trajectory control points R after the change, a moving trajectory TR2 from the start point R1 through each trajectory control point R to the end point R8 is calculated. The This moving trajectory TR2 is shifted in the vicinity of the changed trajectory control point R4 as compared to the moving trajectory TR2 ′ based on each trajectory control point R before the change indicated by the dotted line.

  12 and 13, the case where the swinging direction is “right” has been described, but the same applies to other cases. That is, when the swinging direction is “left”, a reference trajectory on the horizontal plane is determined which starts from the left position of the player character 20 and passes through the front of the player character 20 and ends at the position of the right hand. A plurality of reference control points Q are set in Further, when the swinging direction is “swing down”, a reference trajectory on a vertical plane starting from a position above the player character 20 and passing through the front of the player character 20 and ending at a position near the front is determined. A plurality of reference control points Q are set on the track.

  Further, the moving speed V of the weight 33 is determined based on the detected maximum acceleration αm. FIG. 14 is a diagram illustrating an example of the relationship between the maximum acceleration αm and the movement speed V. In the figure, a graph of the relationship between the maximum acceleration αm and the moving speed V is shown with the horizontal axis representing the maximum acceleration αm and the vertical axis representing the moving speed V. According to the figure, the moving speed V is set to increase in proportion to the maximum acceleration αm. The relationship between the maximum acceleration αm and the moving speed V may not be a proportional relationship as shown in FIG. Thereafter, the weight 33 is controlled to move along the set movement trajectory TR2 at the set movement speed V.

(B) Follow-up Mode The “follow-up mode” is a mode in which, when the player 10 performs a swing operation, the player character 20 swings the weapon 30 following the movement of the game controller 1300. Specifically, the player character 20 swings the right arm 21 holding the weapon 30 in a direction corresponding to the swing operation performed by the player 10. Then, the weapon 30 moves so as to follow the swing.

  The swinging of the weapon 30 of the player character 20 in the follow-up mode is controlled based on the acceleration α detected by the acceleration sensor 1306 of the game controller 1300.

  First, the right arm 21 of the player character 20 is controlled based on the accelerations αx, αy, αz detected by the acceleration sensor 1306. FIG. 15 is a diagram for explaining the control of the right arm of the player character 20. As shown in the figure, the detection coordinate system (Xc, Yc, Zc) of the acceleration sensor 1306 is associated with the local coordinate system (Xp, Yp, Zp) based on the player character 20 in the game space. . In the local coordinate system (Xp, Yp, Zp) of the player character 20, the positive direction of the Zc axis coincides with the direction of the player character 20 in the game space, the positive direction of the Xp axis coincides with the right direction of the player character 20, and Yp The positive axis direction is set to coincide with the vertical direction of the player character 20. Then, the direction (longitudinal direction) of the right arm 21 of the player character 20 is controlled so as to coincide with the direction of the acceleration vector α obtained by combining the detected accelerations αzx, αy, αz. The right arm 21 freely rotates around a predetermined position (for example, the right shoulder) of the player character 20.

  A control point T is set on the blade 32 based on the detected acceleration α. That is, as shown in FIG. 16A, the control is performed at a position that is a predetermined length (control length) L1 along the sword 32 from the starting point S, which is a connection portion between the sword pattern 31 and the sword 32. Point T is set. And the part from the starting point S to the control point T is taken as the rigid part of the state straightened in the direction along the longitudinal direction of the sword pattern 31. However, the control length L1 is shorter than the length (full length) L of the blade 32. The length L of the sword 32 is the length from the starting point S along the sword 32 to the connection position with the weight 33, that is, the length of the sword 32 extending straight (when stretched). It is. In the figure, the weapon 30 is displayed in a simplified manner.

  Further, the control length L1 is determined based on the detected acceleration α. FIG. 4B is a diagram showing an example of the relationship between the magnitude of the acceleration α and the control length L1, and shows a graph with the horizontal axis representing the acceleration α and the vertical axis representing the control length L1. According to the figure, the control length L1 is “0” when the acceleration α is equal to or less than the predetermined value αs, and is set to increase as the acceleration α increases as the acceleration α exceeds the predetermined value αs. However, the maximum length L1m is shorter than the length (full length) L of the blade 32. That is, the control point T is set at the position of the starting point S of the blade 32 when the acceleration α is small. When the acceleration α exceeds a predetermined value αs, the control point T changes to a position closer to the weight 33 as the acceleration α increases. To do.

  Note that the relationship between the acceleration α and the control length L1 may not be the relationship shown in FIG. For example, while the acceleration α is smaller than the predetermined value αt, the control length L1 becomes longer as the acceleration α becomes larger. When the acceleration α becomes larger than the predetermined value αt, the control length L1 gradually becomes shorter as the acceleration α becomes larger. You may set as follows.

  Then, as shown in FIG. 2C, the weapon 30 is fixed so that the longitudinal direction of the sword pattern 31 coincides with the extending direction of the right arm 21 of the player character 20. In other words, the directions of the right arm 21, the sword pattern 31, and the rigid portion from the starting point S to the control point T of the sword blade 32 coincide with each other and are maintained in one piece. Thereby, only the part near weight 33 except for this rigid part among sword blades 32 can move freely. That is, since the portion of the sword blade 32 that can be freely moved is shortened, the followability of the movement of the weight 33 accompanying the swinging of the right arm 21 is enhanced, and the operability is improved for the player.

  Subsequently, control of the weight 33 will be described. FIG. 17 is a diagram for explaining the control of the weight 33, and is a diagram for explaining the calculation direction of the position after a unit frame time (for example, 1/60 second) from the current position K0 of the weight 33. is there. First, the right arm 21 of the player character 20 is controlled based on the detected acceleration vector α, and the positions of the starting point S1 and the control point T1 of the blade 32 after a unit frame time are determined. Next, a provisional position (temporary position) K1 ′ of the weight 33 after a unit frame time when the weight 33 is assumed to be moved according to the current movement vector U0 set for the weight 33 is calculated. Then, a distance D between the control point T1 and the temporary position K1 ′ is calculated.

  If the sum “D + L1” of the distance D and the control length L1 is equal to or less than the length L of the sword 32, the temporary position K1 ′ is the position of the weight 33 after the unit frame time (weight position) as shown in FIG. ) K1. Further, the current movement vector U0 is directly used as the movement vector U1 after the unit frame time.

  On the other hand, when the sum “D + L1” of the distance D and the control length L1 exceeds the length L of the sword 32, as shown in FIG. 19, the current weight position K0 and the control point T1 after the unit frame time On the straight line connecting the positions, and at a position where the distance from the position of the control point T1 is “L2 (= (length L of the blade 32) − (control length L1))” after the unit frame time A weight position (weight position) K1 is set. Then, the sum of the current movement vector U0 and the action vector W is set as the movement vector U1 after the unit frame time. The action vector W is a vector expressing that the weight 33 is pulled by the blade 32, the direction is from the weight position K1 to the position of the control point T1, and the magnitude is proportional to the acceleration α.

[Function configuration]
FIG. 20 is a block diagram showing a functional configuration of the game system 1. According to the figure, the game system 1 functionally includes an operation input unit 110, an image display unit 130, a sound output unit 140, a communication unit 150, a processing unit 200, and a storage unit 300. Configured.

  The operation input unit 110 receives an operation input by the player and outputs an operation signal corresponding to the operation to the processing unit 200. This function is realized by, for example, a button switch, lever, dial, mouse, keyboard, touch panel, various sensors, and the like. In FIG. 1, the game controller 1300 corresponds to this. The operation input unit 110 includes an acceleration sensor 1306 and outputs the detected accelerations αx, αy, αz to the processing unit 200.

  The processing unit 200 performs various arithmetic processes such as overall control of the game system 1, game progress, and image generation. This function is realized by, for example, a processor such as a CPU (CISC type, RISC type) or DSP, an arithmetic device such as an ASIC (gate array or the like), or a control program thereof. In FIG. 1, the CPU mounted on the control unit 1110 corresponds to this. In addition, the processing unit 200 mainly includes a game calculation unit 210 that performs calculation processing related to game execution, an image generation unit 230 that generates a game image based on various data obtained by processing of the game calculation unit 210, And a sound generator 240 for generating game sounds such as sound effects and BGM.

  The game calculation unit 210 executes various game processes based on operation signals input from the operation input unit 110, programs and data read from the storage unit 300, and the like. For example, the current operation mode is determined based on an operation signal input from the operation input unit 110. That is, if the predetermined operation button 1302 is pressed, it is determined as “follow mode”, and if it is not pressed, it is determined as “activation mode”. The determined operation mode is stored in the operation mode data 321.

  Also, the game calculation unit 210. In accordance with an operation signal input from the operation input unit 110, the type of weapon 30 possessed by the player character 20 is switched from among a plurality of types of weapons 30 prepared in advance. Currently, the data of the type of weapon 30 (type of possessed weapon) possessed by the player character 20 is stored in the possessed weapon type data 322.

  In the present embodiment, the game calculation unit 210 includes an activation mode control unit 211 and a follow-up mode control unit 212.

(A) Trigger mode control unit,
The activation mode control unit 211 controls the player character 20 and the weapon 30 in the activation mode. Specifically, the acceleration αz detected by the acceleration sensor 1306 is monitored, and if the acceleration αz exceeds a predetermined threshold (for example, “1.1 G”), the control of the swinging motion of the player character 20 and the weapon are performed. 30 movement control is started (activated).

  That is, first, the player character 20 is caused to perform a motion of swinging up the right arm 21 holding the weapon 30 as a previous operation for swinging the weapon 30. Further, based on the accelerations αx, αy, αz detected by the acceleration sensor 1306, the operation direction (swing direction) of the swing operation performed is determined. That is, if the acceleration αz of the accelerations αx, αy, and αz detected by the acceleration sensor 1306 exceeds a predetermined threshold (eg, “1.1G”), the swing operation is started (the swing operation is performed). And sampling of each acceleration αx, αy, αz is started. That is, the input accelerations αx, αy, αz are captured for a predetermined time at predetermined time intervals (for example, frame time intervals). Then, average accelerations αxa, αya, αza of the sampled accelerations αx, αy, αz are calculated. In addition, for each sampling, an acceleration α that is the magnitude of an acceleration vector obtained by combining the sampled accelerations αx, αy, and αz is calculated, and the maximum acceleration αm is extracted from the calculated acceleration α.

  The sampled acceleration α data is stored in the sampling data 333. FIG. 21 is a diagram illustrating an example of the data configuration of the sampling data 333. According to the figure, the sampling data 333 stores the detected acceleration 333b in association with each sampling timing 333a, and stores the average acceleration 333c and the maximum acceleration 333d. The sampling timing 333a is a sampling timing at predetermined time intervals (for example, frame time intervals). The acceleration 333b stores the values of the acquired accelerations αx, αy, αz and the value of the acceleration α.

  Next, the activation mode control unit 211 refers to the direction determination table 331 based on the calculated average accelerations αxa, αya, αza, and swings the operation direction of the performed swing operation and the weapon 30 of the player character 20. Determine the direction.

  FIG. 22 is a diagram illustrating an example of a data configuration of the direction determination table 331. According to the figure, the direction determination table 331 stores acceleration conditions 331a, a swing direction 331b, and a swing direction 331c in association with each other. The acceleration condition 331a is a condition of the average acceleration values αy and αx. That is, the activation mode control unit 211 determines the swing direction and the swing direction corresponding to the acceleration condition that satisfies the combination of the calculated average acceleration values αx and αy.

  Subsequently, the activation mode control unit 211 calculates the movement trajectory and the movement speed V of the weight 33 of the weapon 30 according to the determined swinging direction. Specifically, with reference to the activation mode weapon data 332 corresponding to the type of weapon 30 currently possessed by the player character 20 (type of possessed weapon), the reference control point Q corresponding to the determined turning direction is determined in the game. Set to space. At this time, of course, the reference control point Q is set according to the direction of the player character 20.

  FIG. 23 is a diagram illustrating an example of a data configuration of the weapon data 332 for activation mode. According to the figure, activation mode weapon data 332 is generated for each type of weapon 30, and the corresponding weapon type 332a, reference trajectory data 332b, reference acceleration 332e, movement speed setting data 332f, collision A determination area 332g and a damage value 332h are stored. The reference trajectory data 332b stores the position of each reference control point 332c in association with each swinging direction 332d. The position of the reference control point 332 c is stored as a coordinate value according to the local coordinate system set for the player character 20. The reference acceleration 332e stores the value of the reference acceleration αp that serves as a reference when setting the trajectory control point R based on the reference control point Q. The moving speed setting data 332f is data defining the relationship between the maximum acceleration αm and the moving speed V, for example, as shown in FIG. 14, for example. 4 is a data table in which values with V are associated with each other. The collision determination area 332g stores a value of the radius r of the collision determination area JA which is a spherical area. The damage value 332h stores a damage value given to the enemy character 40 determined to have collided with the corresponding weapon 30.

  Next, the activation mode control unit 211 sets a trajectory control point R for each set reference control point Q based on the calculated maximum acceleration αm. That is, the trajectory control point R is set at a position on the straight line from the position Pp of the player character 20 toward the reference control point Q and the distance r from the position Pp satisfies the expression (1). However, among these reference control points Q, the start point Q1 and the end point Qn are used as the start point R1 and end point Rn of the trajectory control point R as they are.

  Then, for each set trajectory control point R, refer to the activation mode weapon data 332 corresponding to the type of possessed weapon, and whether the enemy character 40 is located in the collision determination area JA centered on the trajectory control point R. Determine whether or not. When the enemy character 40 is located, the trajectory control point R is changed to the position of the enemy character 40.

  Thereafter, a predetermined interpolation operation (for example, spline interpolation) based on each set trajectory control point R is performed to calculate a moving trajectory TR2 from the start point R1 through each trajectory control point R1 to the end point Rn.

  Further, the activation mode control unit 211 determines the moving speed V of the weight 33 of the weapon 30 with reference to the activation mode weapon data 332 corresponding to the type of the possessed weapon based on the maximum acceleration αm.

  Data of the calculated movement trajectory TR2 and movement speed V is stored in the activation mode control data 334. FIG. 24 is a diagram illustrating an example of a data configuration of the activation mode control data 334. As illustrated in FIG. According to the figure, the activation mode control data 334 stores the position 334b associated with each trajectory control point 334a and stores the calculated movement trajectory 334c and the movement speed 334d. . The position 334b is stored as a coordinate value according to the world coordinate system.

  Thereafter, the activation mode control unit 211 controls the player character 20 and the weapon 30. That is, the player character 20 is caused to perform an action of swinging the right arm 21 in a direction corresponding to the determined swing direction. Further, referring to the activation mode control data 334, the weight 33 of the weapon 30 is moved at the calculated movement speed V along the calculated movement trajectory TR2. Further, along with the movement of the weight 33, the blade 32 that connects the right hand of the player character 20 and the weight 33 is controlled.

  Then, the collision between the weapon 30 and each enemy character 40 is determined. Specifically, a determination process (hit determination) is performed as to whether each of the sword blade 32 and the weight 33 of the weapon 30 collides with each enemy character 40. Then, referring to the activation mode weapon data 332 corresponding to the type of weapon possessed, the enemy character 40 determined to collide is damaged according to the colliding portion of the weapon 30. That is, when the enemy character 40 collides with the weight 33 of the weapon 30, the damage value determined by the activation mode weapon data 332 is given, and when the enemy character 40 collides with the sword 32, the damage value is smaller than the above damage value. A damage value (for example, 0.2 times the damage value of the weapon 30) is given.

  The follow-up mode control unit 212 controls the player character 20 and the weapon 30 in the follow-up mode. Specifically, the swinging motion of the weapon 30 of the player character 20 is controlled from time to time based on the acceleration α detected by the acceleration sensor 1306.

  That is, an acceleration vector α obtained by synthesizing accelerations αx, αy, and αz detected by the acceleration sensor 1306 is calculated every predetermined unit frame time (for example, 1/60 second), and the direction of the right arm 21 is calculated based on the calculated acceleration. Rotate to match the direction of vector α.

  The detected acceleration α data is stored in the detected acceleration data 342. FIG. 25 is a diagram illustrating an example of a data configuration of the detected acceleration data 342. According to the figure, the detected acceleration data 342 stores the accelerations αx, αy, αz detected by the acceleration sensor 1306 and the acceleration magnitude α.

  Next, the follow-up mode control unit 212 controls the weapon 30 accompanying the control of the right arm 21 of the player character 20 for each unit frame time. That is, based on the detected current acceleration α, the control length L1 from the starting point S to the control point T of the blade 32 is calculated with reference to the weapon data 341 for follow-up mode corresponding to the type of weapon possessed, A control point T is set on the blade 32. This control point T is set as a control point T1 after the unit frame time. Then, a portion from the starting point S of the sword blade 32 to the calculated control length L1 is defined as a rigid portion that matches the extension direction of the sword blade 32.

  FIG. 26 is a diagram illustrating an example of a data configuration of the follow-up mode weapon data 341. According to the figure, the follow-up mode weapon data 341 is generated for each type of weapon 30, and the corresponding type 30 341a of the weapon 30, the length 341b of the sword 32, the damage value 341c, and the control length setting data. 341d is stored. The damage value 341c stores a damage value to be given to the enemy character 40 determined to have collided with the corresponding type of weapon 30. The control length setting data 341d is data that defines the relationship between the acceleration α and the control length L1, as shown in an example in FIG. 16B, for example, and the blade 32 defined for each type of weapon 30. The maximum value L1m of the control length L1 and the threshold value of the acceleration αs are based on parameters such as the length L, the weight of the weight 33, and the attack power (strength) that determines the damage value applied to the enemy character 40. It is defined differently. The control length setting data 341d is a graph in FIG. 27, but may be a relational expression representing this graph or a data table in which values of the acceleration α and the control length L1 are associated with each other.

  Subsequently, the follow-up mode control unit 212 calculates a temporary position (temporary position) K1 ′ of the weight 33 after the unit frame time based on the current movement vector U0 set in the weight 33. Then, the distance D between the position of the control point T1 after the unit frame time and the temporary position K1 ′ is calculated, the sum “D + L1” of the calculated distance D and the control length L1, and the length of the blade 32 Compare with L. If “D + L1” is equal to or shorter than the length L of the blade 32, the temporary position K1 ′ is set as the position (weight position) K1 of the weight 33 after the unit frame time. The current movement vector U0 is set as it is as the movement vector U1 after the unit frame time.

  On the other hand, if “D + L1” exceeds the length L of the blade 32, it is on a straight line connecting the current weight position K0 and the position of the control point T1 after the unit frame time, and from the position of the control point T1. A weight position (weight position) K1 after the unit frame time is set at a position where the distance is “L2 (= L−L1)”. Also, an action vector W that is a predetermined multiple (n times) of the detected acceleration vector α and is directed from the weight position K1 to the position of the control point T1 is calculated, and this action vector W and the current movement vector U0 are calculated. Is set as the movement vector U1 after the unit frame time.

  Here, the calculated data such as each position is stored in the follow-up mode control data 343. FIG. 27 is a diagram illustrating an example of a data configuration of the follow-up mode control data 343. According to the figure, the follow-up mode control data 343 includes a control length 343a, a start point S position 343b of the blade 32, a control point T position 343c, a weight 33 position 343d, and a movement vector 343e. For each, the current value and the value after the unit frame time are stored.

  In FIG. 20, the image generation unit 230 generates a game image for displaying the game screen based on the calculation result by the game calculation unit 210, and outputs an image signal of the generated image to the image display unit 130. Based on the image signal from the image generation unit 230, the image display unit 130 displays the game screen while redrawing a screen of one frame at a predetermined unit time interval, for example, every 1/60 seconds. This function is realized by hardware such as CRT, LCD, ELD, PDP, and HMD. In FIG. 1, the display 1202 corresponds to this.

  The sound generation unit 240 generates game sounds such as sound effects and BGM used during the game, and outputs a sound signal of the generated game sound to the sound output unit 140. The sound output unit 140 outputs game sounds such as BGM and sound effects based on the sound signal from the sound generation unit 240. This function is realized by, for example, a speaker. In FIG. 1, the speaker 1204 corresponds to this.

  The communication unit 150 is connected to a communication line according to a control signal from the processing unit 200 and performs data communication with an external device. This function is realized by a wireless communication module, a wired communication cable jack, a control circuit, or the like. In FIG. 1, the communication device 1112 corresponds to this.

  The storage unit 300 stores a system program for realizing various functions for causing the processing unit 200 to control the game system 1 in an integrated manner, a program and data necessary for executing the game, and the processing unit 200 is used as a work area, and temporarily stores calculation results executed by the processing unit 200 according to various programs, input data input from the operation input unit 110, and the like. This function is realized by, for example, various IC memories, hard disks, CD-ROMs, DVDs, MOs, RAMs, VRAMs, and the like. In FIG. 1, the memory mounted on the control unit 1110 corresponds to this. In the present embodiment, the storage unit 300 stores a game program 310 for causing the processing unit 200 to function as the game calculation unit 210 as a program, and includes operation mode data 321, possessed weapon type data 322 as data, Character data 323, activation mode data group 330, and follow-up mode data group 340 are stored.

  The character data 323 is data related to various characters such as the player character 20 and the enemy character 40 appearing in the game, and stores current position coordinates, ability values, owned items (including the weapon 30), motion data, and the like. .

  The activation mode data group 330 is a data group used in the activation mode, and includes a direction determination table 331, activation mode weapon data 332, sampling data 333, and activation mode control data 334. The follow-up mode data group 340 is a data group used in the follow-up mode, and includes follow-up mode weapon data 341, detected acceleration data 342, and follow-up mode control data 343.

[Process flow]
FIG. 28 is a flowchart for explaining the flow of the game processing in the present embodiment. This process is realized by the game calculation unit 210 executing the game program 310. According to the figure, the game calculation unit 210 first sets a game stage and sets a game space in which each character such as the player character 20 and the enemy character 40 is arranged (step A1). Next, in accordance with an input instruction from the operation input unit 110, the type of weapon 30 possessed by the player character 20 is switched (step A3). Further, according to an input instruction from the operation input unit 110, movement control of the player character 20 and control of other characters including the enemy character 40 are performed (step A5). Subsequently, the game calculation unit 210 determines the current operation mode (step A7). If the determined operation mode is “activation mode” (step A9: “activation”), the activation mode control unit 211 performs activation mode processing (step A11).

  FIG. 29 is a flowchart for explaining the flow of the activation mode process. According to the figure, the activation mode control unit 211 determines whether or not the acceleration component αz input from the acceleration sensor 1306 exceeds a predetermined threshold (for example, “1.1 G”). (Step B1: YES), the player character 20 is caused to start a swing-up operation of the predetermined weapon 30 (Step B3). Next, a swing direction determination process is performed to determine the swing direction of the game controller 1300 made by the player 10 (step B5).

  FIG. 30 is a flowchart for explaining the flow of the swing direction determination process. According to the figure, the activation mode control unit 211 samples the accelerations αx, αy, αz input from the acceleration sensor 1306 for a predetermined time at predetermined time intervals (for example, frame time intervals) (step C1). ). Next, average accelerations αxa, αya, αza which are average values of the sampled accelerations αx, αy, αz are calculated (step C3). Further, for each sampling, an acceleration α that is the magnitude of an acceleration vector obtained by combining the accelerations αx, αy, and αz is calculated, and the maximum acceleration αm that is the maximum value of these accelerations α is extracted (step C5). . Then, with reference to the direction determination table 331, the performed swing direction is determined based on the calculated average accelerations αxa, αya, αza (step C7). When the above processing is performed, the swing direction determination processing ends.

  When the swing direction determination process ends, the activation mode control unit 211 refers to the direction determination table 331 and determines the swinging direction of the weapon 30 of the player character 20 based on the determined swing direction (step B7). Subsequently, a movement trajectory calculation process is performed to calculate the movement trajectory TR2 and the movement speed V of the weapon 30 (step B9).

  FIG. 31 is a flowchart for explaining the flow of the movement trajectory calculation process. According to the figure, the activation mode control unit 211 refers to the activation mode weapon data 332 corresponding to the type of possessed weapon, and sets each reference control point Q corresponding to the determined turning direction in the game space. (Step D1). At this time, each reference control point Q is set in accordance with the direction (orientation) of the player character 20 so that the turning direction is based on the player character 20. Next, for each set reference control point Q, a trajectory control point R is set based on the ratio between the calculated maximum acceleration αm and the reference acceleration αp (step D3). Subsequently, for each set trajectory control point R, it is determined whether or not an enemy character is located in the collision determination area JA (step D5). If so, the trajectory control point R is placed at the position of the enemy character 40. Is changed (step D7). Thereafter, an interpolation calculation based on each of these movement control points R is performed to calculate a movement trajectory TR2 (step D9). Further, the moving speed V is calculated based on the maximum acceleration αm (step D11). When the above processing is performed, the movement trajectory calculation processing is terminated.

  When the movement trajectory calculation process ends, the activation mode control unit 211 causes the player character 20 to start swinging the weapon 30 in the determined swing direction (step B11). Further, the movement control of the weight 33 of the weapon 30 is started at the movement speed V calculated along the calculated movement trajectory TR2 (step B13). When the above processing is performed, the activation mode processing is terminated.

  In FIG. 29, when the activation mode process ends, the game calculation unit 210 determines a collision between the weapon 30 and each enemy character 40 (step A13), and damages each enemy character 40 according to the collision determination result. (Step A15). Next, it is determined whether or not both the swinging motion control of the player character 20 and the movement control of the weapon 30 are finished. If not finished (step A17: NO), the process returns to step A13.

  FIG. 32 is a flowchart for explaining the flow of the follow-up mode process. According to the figure, the follow-up mode control unit 212 takes in accelerations αx, αy, αz input from the acceleration sensor 1306 (step E1), and calculates a combined acceleration vector α of the taken accelerations αx, αy, αz. (Step E3). Next, the right arm of the player character 20 is controlled to coincide with the calculated direction of acceleration α (step E5).

  Subsequently, based on the acceleration α which is the magnitude of the calculated acceleration vector α, the control length L1 is calculated with reference to the follow-up mode weapon data 341 corresponding to the type of the possessed weapon (step E7), and the blade 32 The control point T1 after the unit frame time is set at a position where the length from the start point S is the calculated control length L1 (step E9). Then, the portion from the starting point S of the sword blade 32 to the control point T1 is made to be in a state of being straightened by matching the extension direction of the sword blade 32 (step E11).

  Further, the temporary position K1 ′ of the weight 33 after the unit frame time when the weight 33 is moved based on the current movement vector U0 is calculated (step E13), and the position of the string starting point S1 and the temporary position K1 are calculated. The distance D between 'is calculated (step E15). Then, the sum “D + L1” of the calculated distance D and the control length L1 is compared with the length L of the blade 32.

  As a result, if “D + L1” is equal to or less than the length L of the blade 32 (step E17: YES), the temporary position K1 ′ is set as the weight position K1 after the unit frame time (step E19). The movement vector U0 is set as it is as the movement vector U1 after the unit frame time (step E21).

  On the other hand, if “D + L1” is longer than the length L of the blade 32 (step E17: NO), it is on the straight line connecting the current weight position K0 and the control point T1 after the unit frame time, and the control point T1. The position where the distance from the position of “L-L1” is set as the weight position K1 after the unit frame time (step E23). Next, an action vector W whose direction is the direction from the weight position K1 to the position of the starting point S1 of the blade 32 and whose magnitude is a predetermined multiple (n times) of the acceleration α is calculated (step E25). The sum of the action vector W and the current movement vector U0 is set as the movement vector U1 after the unit frame time (step E27).

  Thereafter, the follow-up mode control unit 212 arranges the weight 33 at the weight position K1 after the set unit frame time, and the blade 32 according to the distance between the starting point S of the blade 32 and the weight position K1. The blades 32 are controlled to have an appropriate angle (step E29) so that the angle between the adjacent blades is within a predetermined angle. When the above processing is performed, the tracking mode control unit 212 ends the tracking mode processing.

  In FIG. 29, when the follow-up mode process ends, the game calculation unit 210 determines a collision between the weapon 30 and each enemy character 40 (step A23), and damages each enemy character 40 according to the collision determination result. (Step A25).

  Thereafter, the game calculation unit 210 determines whether or not to end the game. If the game is not ended (step A27: NO), the process returns to step A3, and if the game is ended (step A27: YES), game processing is performed. Exit.

[Action / Effect]
Thus, according to the present embodiment, a new game operation such as swinging the player character 20 around the weapon 30 in accordance with the operation of swinging the game controller 1300 is realized. There are two types of operation modes, “activation mode” and “follow-up mode”, which are switched depending on whether or not the operation button 1302 is pressed.

  In the “invoking mode”, when any one of a plurality of predetermined swing operations is performed, the player character 20 starts a swinging motion associated with the performed swing operation. That is, the operation direction (swing direction) of the swing operation made based on the value of the acceleration α detected by the acceleration sensor 1306 incorporated in the game controller 1300 is determined, and further the swing direction of the weapon 30 of the player character 20 is determined. Is done. Next, the movement trajectory TR2 and the movement speed V of the weight 33 of the weapon 30 are determined according to the determined turning direction, and the weight 33 of the weapon 30 is controlled to move at the movement speed V determined along the determined movement trajectory TR2. The In the “follow-up mode”, the player character 20 performs an action following the operation of the game controller 1300 at any time. That is, the right arm 21 of the player character 20 is controlled from time to time based on the acceleration α detected by the acceleration sensor 1306, and the weight 33 of the weapon 30 is moved and controlled following the movement of the right arm 21.

  As described above, even if the operation of moving the game controller 1300 is the same, the control method of the player character 20 differs depending on the operation mode, and thus the action of the player character 20 differs. The player can easily switch to a desired operation mode depending on whether or not the operation button 1302 is pressed. Therefore, it is possible to improve the fun of game operation using the game controller 1300 including the acceleration sensor 1306.

[Modification]
Note that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and it is needless to say that the embodiments can be appropriately changed without departing from the spirit of the present invention.

(A) Switching of operation mode For example, in the above-described embodiment, the operation mode is selected depending on whether or not one operation button 1302 is pressed. This is realized by the following method. You may do it.

(A-1) Pressing of the operation button 1302 For example, the operation mode may be switched every time the operation button 1302 is pressed. Specifically, when the current operation mode is “invocation mode”, the operation button 1302 is pressed once to switch from “invocation mode” to “follow-up mode”. Next, when the operation button 1302 is pressed again, the “following mode” is switched to the “activation mode”. By doing so, it is not necessary to keep the operation button 1302 pressed, and the operability is further improved.

(A-2) Attitude of game controller 1300 Further, the game controller 1300 may be switched according to the attitude of the game controller 1300. Specifically, different postures of the game controller 1300 are associated with each operation mode in advance. Then, the attitude of the game controller 1300 is determined based on the accelerations αx, αy, and αz detected by the acceleration sensor 1306. If the determined attitude is a determined attitude, the operation mode corresponding to the attitude is switched. For example, in the “invoking mode”, the front end portion 1312 of the game controller 1300 is directed upward and the posture in which the longitudinal direction is along the vertical direction is associated. In the “follow-up mode”, the front end portion 1312 of the game controller 1300 is moved downward. The posture in which the longitudinal direction is along the vertical direction is associated. When the game controller 1300 is stationary in the former posture, the acceleration α, αx, αz detected by the acceleration sensor 1306 is substantially “1.0G”, and the acceleration αx, αy is substantially zero (0). It becomes. When the game controller 1300 is stationary in the latter posture, the acceleration α, αx, αz detected by the acceleration sensor 1306 is substantially “−1.0 G”, and the acceleration αx, αy is substantially zero. (0). Therefore, when the detected accelerations αx, αy, αz are the above values for a predetermined time, it is determined that an operation mode selection operation has been performed, and the corresponding operation mode is switched.

(A-3) Combination of the operation button 1302 and the acceleration sensor 1306 Further, the operation button 1302 and the acceleration sensor 1306 are switched according to the combination of the operation buttons and the accelerations αx, αy, and αz detected by the acceleration sensor 1306. good. Specifically, the game controller 1300 has a plurality of operation buttons, and an operation mode is set for each combination of the pressing operation of each operation button and each acceleration αx, αy, αz detected by the acceleration sensor 1306. Correlate. When these combinations of operations are performed, the corresponding operation mode is switched. For example, one operation mode is associated with “pressing the A button and B button simultaneously”, and the other operation mode is associated with “pressing the A button with the tip 1312 of the game controller 1300 vertically downward”.

(A-4)
Furthermore, the operation button 1302 may be configured to be able to detect the pressing amount and the pressing pressure, and the operation mode may be switched according to the pressing operation of the operation button 1302 itself. For example, an operation condition and an operation mode are associated with each other such as one operation mode for strong or deep press and the other operation mode for light or shallow press. Then, the operation mode is switched to the operation mode corresponding to the pressed amount or pressing pressure of the operation button 1302 made.

(B) Correction of Detected Acceleration The accelerations αx, αy, αz detected by the acceleration sensor 1306 may be corrected. Specifically, for example, when a predetermined operation (for example, pressing of the cross key 1304 or another operation button not shown) is performed on the game controller 1300, the values of the detected accelerations αx, αy, αz are multiplied by a predetermined value. (For example, “1.5 times” or “0.8 times”) may be used.

  Further, the correction of the acceleration α and the selection of the operation mode may be combined. Specifically, each of the plurality of operation buttons of the game controller 1300 is associated with each combination of each operation mode and whether or not the acceleration α is corrected. Then, the mode is switched to the operation mode corresponding to the pressed button, and it is determined whether or not to correct the acceleration α. For example, “right” of the cross key 1304 is associated with “correction of acceleration α in activation mode”, “left” is associated with “no correction of acceleration α in activation mode”, and “up” is “in tracking mode”. “Acceleration α is corrected” is associated, and “below” is associated with “no correction of acceleration α in follow-up mode”.

(C) Game controller 1300
(C-1) Speaker Moreover, the game controller 1300 may incorporate a speaker. And the sound according to operation mode is output from this speaker. Specifically, different notification sounds are associated with the operation modes in advance. For example, when the operation mode is switched, a notification sound corresponding to the switched operation mode is output. Here, “sound” includes three sound elements of “pitch”, “volume”, and “sound quality”. Accordingly, it is desirable that one or two of these sound elements be associated with different notification sounds for each operation mode.

  Further, a sound corresponding to the magnitude of the acceleration α detected from the acceleration sensor 1306 may be output from a speaker. In this case, for example, a sound obtained by gradually changing one or two of the above sound elements according to the magnitude of the acceleration α is output. Further, in this case, a sound corresponding to the combination of the detected acceleration α and the current operation mode may be output. At this time, for example, one or two of the above-described sound elements are gradually changed according to the magnitude of the acceleration α, and the remaining one or two sound elements are sound corresponding to the current operation mode. Is output. For example, the volume (sound volume) is varied according to the acceleration α and output, and the pitch (pitch) is varied according to the operation mode.

  Further, when the magnitude of the acceleration α detected by the acceleration sensor 1306 exceeds the magnitude of the acceleration α that can be detected by a normal swing operation, a warning sound for notifying the player that the swing is too strong is output. Anyway.

(C-2) Vibrator Further, the game controller 1300 may incorporate a vibrator. And this vibrator is vibrated with the vibration pattern according to the operation mode. Specifically, different vibration patterns are associated with each operation mode in advance. For example, when the operation mode is switched, the vibrator is vibrated with a vibration pattern corresponding to the operation mode after switching.

  Further, the vibrator may be vibrated with a vibration pattern corresponding to the magnitude of the acceleration α detected from the acceleration sensor 1306. In this case, for example, a vibration pattern in which the number and interval of vibrations are gradually changed according to the magnitude of the acceleration α is used. Furthermore, you may make it vibrate with the vibration pattern according to the combination of the magnitude | size of the detected acceleration (alpha) and the present operation mode.

  Further, when the magnitude of the acceleration α detected by the acceleration sensor 1306 exceeds the magnitude of the acceleration α that can be detected by a normal swing operation, a warning vibration pattern for informing the player that the swing is too strong. You may make it vibrate with.

(D) Warning In addition, a warning may be given when the game controller 1300 is shaken too much. Specifically, when the magnitude of the acceleration α detected by the acceleration sensor 1306 is equal to or greater than a predetermined magnitude (threshold), a message indicating that the swing is too strong is displayed on the display 1202. Further, a predetermined warning sound for notifying the player that the swing is too strong may be output from the built-in speaker, or the built-in vibrator is vibrated with a predetermined vibration pattern for warning. May be.

(E) Activation mode In the activation mode, the following may be performed.
(E-1) Trajectory control point R
For example, the trajectory control point R set in the game space may be notified to the player.
Specifically, a predetermined mark body (object) serving as a mark is arranged at the position of each trajectory control point R. Accordingly, the weight 34 moves so as to pass through these landmarks. Of course, this landmark does not affect other objects such as the blade 32 and the weight 33 of the weapon 30.

  Further, the position of the trajectory control point R may be varied by a player's instruction operation. Specifically, in the above-described embodiment, the position of each trajectory control point R is set to a position where the distance r from the position Pp of the player character 20 is the distance r given by the above equation (1). However, this is set to a position where the distance r from the position Pp is a distance r ′ (= r × k) obtained by multiplying the distance r calculated by the expression (1) by a predetermined coefficient k. I will decide. Then, the coefficient k is changed according to a predetermined operation (for example, pressing of the cross key 1304 or other operation buttons not shown) in the game controller 1300. For example, the coefficient k is set to “1.0” when the swing operation is detected in a state where the operation button 1302 is not pressed, and the coefficient k is set to “1.0” when the swing operation is detected in the pressed state. 1.5 ".

(E-2) Determination of Swing Operation In addition, the threshold value of acceleration α for determining the operation direction of the swing operation may be changed by a player's instruction operation. Specifically, threshold values of average accelerations αx and αy defined as acceleration conditions in the direction determination table 331 shown in FIG. 22 (αx is “0.9G” and αy is “0.0” in FIG. 22), The game controller 1300 changes in accordance with a predetermined operation (for example, pressing of the operation button 1302). For example, when the operation button 1302 is not pressed, the threshold value determined in the direction determination table 321 is used, and when the operation button 1302 is pressed, the threshold value is increased or decreased (for example, “1.2 times” or “0.8 times”). )).

(E-3) Player's dominant hand In the above-described embodiment, the player 10 has been described as holding the game controller 1300 with the right hand, but the player may be able to set which hand to hold with the right or left hand. Specifically, as the direction determination table 331 in “invoking mode”, in addition to the right hand shown in FIG. 22 as an example, a left hand is also prepared. Then, for example, before the game is started, whether the player holds with the right hand or the left hand is input and set, and the operation direction of the swing operation performed using the input determination direction direction determination table 331 is set. judge.

(F) Follow-up mode In the follow-up mode, the following may be performed.
For example, in the above-described embodiment, the control length L1 is determined based on the detected acceleration α, so that the control point T is set on the blade 32. However, this can be changed as follows. It may be set.

(A) Instructing operation by player For example, it is varied according to the instructing operation by the player. Specifically, candidate positions of the control point T of the sword 32 are determined in advance, such as the position of the starting point P, the connection position with the weight 33, and the position that bisects the entire length of the sword 32. Then, a control point T is set at a candidate position corresponding to a predetermined operation (for example, pressing of the operation button 1302) in the game controller 1300. For example, when the operation button 1302 is not pressed, the control point T is set to the position of the starting point P of the blade 32, and when the operation is performed, the connection to the weight 33 of the blade 32 is performed. Set to position. That is, the rigid portion of the blade 32 is switched by pressing the operation button 1302.

(B) Parameters of the player character 20 Further, the parameters may be varied according to the parameters of the player character 20. Specifically, according to the values of parameters that can be changed as the game progresses, such as the experience value and level of the player character 20, the possessed items, and the type and number of enemy characters that have battled, A control point T is set. For example, the control point T is set at a position closer to the weight 33 of the sword body 32 (position closer to the sword tip) as the experience value or level increases.

(C) Position of Weapon 30 Further, the position may be varied according to the position of the weapon 30. Specifically, according to the position of the weight 33 in the game space, for example, the control point T is set closer to the start point P of the sword 32 as the height of the position of the weight 33 from the ground surface is higher. To set. Further, when the weight 33 is positioned in front of or behind the player character 20, the control point T is set at a position close to the weight 33 of the sword 32 and is positioned to the right or left. The weight 33 is set such that the control point T is set closer to the weight 33 of the sword 32 as the distance between the weight 33 and the player character 20 is longer. You may set according to the relative positional relationship with the player character 20. FIG.

(D) Movement speed of weapon 30 Further, it may be variable according to the movement speed of the weapon 30. Specifically, the control point T is set at a position closer to the connection position with the weight 33 as the movement vector U that determines the movement speed of the weight 33 is smaller, that is, the movement speed of the weight 33 is slower. The rigid portion of the body 23 is lengthened to improve the follow-up performance of the operation.

(G) Length of the right arm 21 Further, the length of the right arm 21 of the player character 20 may be varied according to the detected acceleration α, for example. For example, as the acceleration α increases, the length of the right arm 21 is gradually increased. In this case, the length L of the blade 32 may be fixed, or the length L of the blade 32 may be further varied.

(H) Weapon 30
(H-1) Parameters For example, the parameters of the weapon 30 such as the length L of the sword 32 of the weapon 30, the weight of the weight 33, and the attack power (strength) that determines the damage value applied to the enemy character 40 are varied. Anyway. Specifically, for example, it varies based on the progress of the game, such as the detected acceleration α, the level of the player character 20 and the period of use so far. Here, when the length L of the sword blade 32 is varied, it is desirable to adjust the interval between the joints of the blades constituting the sword blade 32. However, when the variable amount of the length L is larger or smaller than a certain level, the number of blades constituting the blade 32 may be increased or decreased. Alternatively, the blade length may be increased to a predetermined maximum length or decreased to a minimum length.

(H-2) Shape Further, in the above-described embodiment, the weapon 30 is similar to the “belly sword”, but other weapons may be used. For example, it may have a shape imitating a “yoyo” in which a moving body of a certain size is attached to one end of a string-like body that is a connection body. At this time, this string-like body may be an elastic body such as a rubber string or a spring. Moreover, it is good also as a shape which attached the weight to the front-end | tip of the chain | strand which is a connection body. That is, the weapon 30 may be any one as long as it is configured to attack the enemy character 40 by swinging it around. Further, the connection body may be invisible. Furthermore, the weapon 30 does not have a connection body and does not need to be connected to the player character 20 as in the case of a weapon imitating a “boomerang”, for example.

  Further, as shown in FIG. 33, the weapon 30 may not have the weight 33 but may have a sword pattern 31 and a sword 32. In this case, among the plurality of blades 34 connected in a bellows shape constituting the sword body 32, the blade 34a corresponding to the sword tip is controlled as a moving body in place of the weight 33, and the same control as in the above embodiment is performed. Further, when the weapon 30 shown in the figure collides with the enemy character 40, the damage value to be given to the enemy character 40 is varied depending on which of the plurality of blades 34 constituting the blade 32 has collided. Anyway.

  Alternatively, the weapon 30 may be configured such that the weight 33 attached to the sword tip of the sword blade 32 can be separated from the sword blade 32 and fired. Specifically, when a predetermined operation (for example, an operation of pressing the operation button 1302) is performed on the game controller 1300, the weight 33 is separated from the blade 32 and the movement is controlled independently so that the weight 33 is fired. In this case, the moving speed of the weight 33 after separation may be controlled in accordance with the number of times the weight 33 has circulated around the player character 20 in the game space. For example, as the number of laps increases, the moving speed of the weight 33 after separation is increased.

(I) Type of game Moreover, although the above-mentioned embodiment demonstrated the case where it applied to the fighting fighting game, it is applicable also to another game. In other games, the present invention is applied not to weapons but to various instruments used by the player character.

  For example, the present invention is applied to a tool (apparatus) that is used in a scene of climbing a castle wall and has a hook (moving body) connected to the tip of a rope (connecting body). That is, by swinging the rope and performing a predetermined throwing instruction operation, the tip of the buttock is thrown (fired), and the buttock is used to be hooked on the upper part of the castle wall. Depending on the number of times the player has circulated around the player character, the flying distance of the thrown buttocks may be determined. For example, the greater the number of laps, the longer the flight distance. Further, as a similar instrument, it can be similarly applied to a weapon that throws a rope whose tip is formed in a ring shape and catches another character.
