Description

  The present invention relates to a program and an information processing apparatus, and more particularly to a program to be executed by a computer of an information processing apparatus provided with coordinate instruction means and an information processing apparatus provided with coordinate instruction means.

In recent years, electronic game devices have been widely used. In the electronic game device, the game program moves and changes various characters displayed on the screen in accordance with the operation of the player, and the game is played by changing the situation. Conventionally, a controller provided with direction keys and operation keys has been used to operate player characters and the like displayed on the screen. Furthermore, in order to simplify the operation, an electronic game device is also disclosed in which a touch panel is provided on a display screen for displaying a game screen so that the game screen can be directly operated (for example, Patent Document 1).
JP 2002-939 A

  However, the touch operation in the electronic game device disclosed in Patent Document 1 described above is a selection operation, or the player character is moved toward the touched position, or the moving speed of the player character along the speed of tracing the touch panel. It was something to change. Therefore, for example, when the player performs a touch operation while wondering what touch operation to perform, such as when the player moves the finger around while touching the touch panel, the character is changed according to the touch position. Since the player moves, the player character moves in a stray manner. Therefore, if the player is at a loss of operation, the player character has performed the above operation with a clear intention to cause the player character to perform a predetermined action, particularly an action other than moving. At this time, contrary to the player's intention, the player character makes the inside of the screen roar, making it difficult for the player character to realize the action intended by the player. Therefore, there has been a problem that the operability of the operation using the touch panel is lowered.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a program and an information processing apparatus that improve the operability of an operation using coordinate instruction means such as a touch panel.

  The present invention employs the following configuration in order to solve the above problems. Note that the reference numerals in parentheses, supplementary explanations, and the like are examples of the correspondence with the embodiments described later in order to help understanding of the present invention, and do not limit the present invention.

  A first invention is a program to be executed by a computer of an information processing apparatus provided with coordinate instruction means, an object display step (S7), an object movement control step (S5), and an instruction history storage step (S8). The first determination step (S22, S23) and the movement restriction step (S4, S44) are executed by the computer. In the object display step, the image data of the object is read and displayed on the display device. The object movement control step controls the movement of the object according to the designated coordinates by the coordinate designating means. Here, the object is a concept including, for example, a game object such as a player character in the game process and other objects in information processing such as a cursor and an icon. The instruction history storage step stores the history information of the instruction coordinates by the coordinate instruction means. In the first determination step, it is determined based on the history information stored in the instruction history storage step whether or not a plurality of pieces of position coordinate information relating to a series of coordinate instructions satisfy a predetermined condition. In the movement restriction step, when it is determined in the first determination step that the predetermined condition is satisfied, a predetermined restriction is applied regarding the movement of the object in the object movement control step. Here, the coordinate instruction means includes, for example, a pointing device such as a mouse in addition to a touch panel and a touch screen.

Further, the following processing is performed in the object movement control step.
(1) The object moves on the screen or in the virtual space on the basis of the latest or corresponding pointed coordinate. (A) The screen position corresponding to the pointed coordinate by the coordinate pointing means becomes the display position of the object. The display position of the object is updated (“screen position corresponding to the designated coordinates”: the correspondence between the designated coordinates and the screen coordinates is set in the apparatus). Note that the display position of the object may be updated by a predetermined distance (a fixed distance or a variable distance may be used) in a direction from the current display position of the object toward the screen position corresponding to the designated coordinates. After the coordinate instruction by the coordinate instruction means is stopped, the object position may not be updated, or the object position may be continuously updated based on the last instruction coordinates (in the latter case, the coordinate instruction means). The object gradually moves toward the last designated coordinate even after the coordinate designation by is stopped). Note that the moving speed of the object (typically, the amount of movement per frame) may be changed according to the distance between the current display position of the object and the screen position corresponding to the designated coordinates. That is, the moving speed of the object (typically, the moving amount per frame) may be increased as the distance between the current display position of the object and the screen position corresponding to the designated coordinates is increased.
(B) The virtual space position of the object is updated so that the position in the virtual space corresponding to the designated coordinate by the coordinate designating means becomes the position in the virtual space of the object (“virtual space position corresponding to the designated coordinate”: The correspondence between the designated coordinates and the screen coordinates is set by the apparatus, and the virtual space position corresponding to the screen coordinates is calculated according to the information of the virtual space area currently displayed on the screen). Note that the virtual space position of the object may be updated by a predetermined distance in the direction from the current virtual space position of the object toward the virtual space position corresponding to the designated coordinates. Note that the moving speed of the object (typically, the amount of movement per frame) may be changed according to the distance between the current virtual space position of the object and the virtual space position corresponding to the designated coordinates. That is, as the distance between the current virtual space position of the object and the virtual space position corresponding to the designated coordinates increases, the moving speed of the object (typically, the amount of movement per frame) may be increased.
(C) The movement direction of the object (the movement direction on the screen or the movement direction in the virtual space) is determined according to the designated coordinates by the coordinate designating means. For example, the moving direction of the object is determined according to the direction from the reference coordinates of the coordinate instruction means to the instruction coordinates. For example, in the case where the designated coordinate system of the coordinate designating unit is (0, 0) in the upper left and (Xm, Ym) in the lower right, the reference coordinates are (Xi, Ys), for example, and the designated coordinates are (Xi, Ys). Yi), if Xi <Xs, the object moves up the screen or in the forward direction of the object (the direction in which the object is facing in the virtual space), and if Xi> Xs, the object moves down the screen or If the object moves in the backward direction (the direction opposite to the direction in which the object is facing in the virtual space) and Yi <Ys, the object is on the left side of the screen or in the left direction of the object (the object is facing in the virtual space) If Yi> Ys, the object moves to the right of the screen or to the right of the object (temporary Move the direction in which the object is facing in the right direction) as a reference in space. Alternatively, the moving direction of the object may be determined according to the area including the designated coordinates by the coordinate designating means. For example, the designated coordinate system of the coordinate designating unit is divided into four or eight areas, and each area is divided into an area for instructing movement in the upper direction of the screen or the object in the forward direction and the lower direction of the screen or in the backward direction of the object. Assigned to the area for instructing movement of the object to the right of the screen or to the right of the object, and the area for instructing movement of the object to the left of the screen or to the left of the object. In the case of division, the object is moved in an oblique direction such as a diagonal upper right direction of the screen), and the object is moved according to which region the designated coordinates are included.
(2) The object moves on the screen or in the virtual space based on the history of the designated coordinates by the coordinate designating means. Direction of change of the designated coordinates by the coordinate designating means (starting from the previous designated coordinates as the current designated coordinates) Move the object based on the heading direction. For example, when the designated coordinate moves in the upward direction in the designated coordinate system, the object is moved upward on the screen or forward of the object.
Also, the object movement control step typically controls the movement of the object based on the designated coordinates (typically the latest or similar time) of the coordinate designating means. For example, even if the movement of the object is controlled based on the designated coordinates one frame before the coordinate designating means, the operational effects of the present invention are not lost. Further, when the object moves in the virtual space, the object may be displayed by displaying the object at a fixed position on the screen and scrolling the virtual space image.

The instruction history storage step stores at least one (at least previous) instruction coordinates in the past. The first determination step and the second determination step determine whether or not a plurality of pieces of position coordinate information relating to a series of coordinate instructions satisfy a predetermined condition based on the history information stored in the instruction history storage step. For example, when determining whether or not the past n-point indicated coordinates satisfy a predetermined condition, the past n-point (or more) indicated coordinates may be stored as history information, or n− One point (for example, only the previous designated coordinates) is stored and determined from the n-1 point designated coordinates (for example, determined from the previous designated coordinates and the current designated coordinates only), By accumulating the determination result, for example, it is recorded that the determination result is affirmative and it is determined that the affirmation state continues, or the parameter is increased or decreased according to the determination result to the value of the parameter. Judgment according to It may be or.
In addition, the following processes are performed in the first determination step.
(1) A certain point in the past (for example, a coordinate instruction start point, a point in time for a predetermined time or a frame before the present point, and the displacement between the previous pointed coordinates and the current pointed coordinates (touch speed in the case of a touch panel) becomes a certain level or more. Whether or not a series of a plurality of designated coordinates from the point in time or the point in time when the previous designated coordinate was detected) to a predetermined point (typically up to the latest point or a point equivalent thereto) satisfies a predetermined condition. judge.
(2) A certain point in the past (for example, a coordinate instruction start point, a point in time for a predetermined time or a predetermined frame from the present point, and the displacement between the previous pointed coordinates and the current pointed coordinates (touch speed in the case of a touch panel) becomes a certain level or more. Whether or not a series of a plurality of designated coordinates from the point in time or the point in time when the previous designated coordinate was detected) to a predetermined point (typically up to the latest point or a point equivalent thereto) satisfies a predetermined condition. When the determination is positive, the predetermined parameter is increased (decreased). Further, it is determined that the parameter is equal to or greater than a predetermined value (ie, is equal to or less than a predetermined value).
Here, the “predetermined conditions” used in the first determination step include the following.
(1) Whether the distance between the previous designated coordinate and the current designated coordinate is greater than or equal to a predetermined value (may be an average from a past point in time to a predetermined point)
(2) A trajectory connecting a series of a plurality of designated coordinates in the order of detection satisfies a predetermined condition (a match with a predetermined pattern such as figure recognition or character recognition may be determined, or a trajectory based on a series of designated coordinates. (It may be a determination that indicates a rotation operation or that a straight line is drawn in a predetermined direction)
In the first determination step, it is preferable to determine whether a series of a plurality of designated coordinates satisfy a predetermined condition while the coordinate designation is continued. That is, when there is no more coordinate instruction by the coordinate instruction means, the first determination step may not refer to the previous history. In addition, the “plurality of position coordinate information related to a series of coordinate instructions” to be determined in the first determination step may be only the history information stored in the instruction history storage step. Typically, both the history information stored by the instruction history storage step is included. That is, in the first determination step, it is determined based on the latest designated coordinates and the history information stored in the designated history storage step that a predetermined condition of the designated coordinates input from a certain past time to the present is satisfied. It is typical.

  Further, in the movement restriction step, the movement of the object by the object movement control step may be stopped (movement by the object movement control step is set to 0), or the movement speed may be restricted. In the latter case, a value obtained by subtracting a predetermined amount (predetermined ratio) from the movement amount (or a predetermined fixed movement amount) calculated in the object movement control step may be used, or the movement amount calculated in the object movement control step may be The movement amount calculated by the object movement control step may be limited to a predetermined value when it is equal to or greater than a predetermined value, or by changing a coefficient of an expression for calculating the movement amount used by the object movement control step. The maximum value may be reduced).

In a second aspect based on the first aspect, the program causes the computer to further execute a second determination step (S12) and an additional control step (S15). In the second determination step, it is determined whether the history of the designated coordinates by the coordinate designating unit satisfies a predetermined condition based on the history information stored in the designated history storage step. The additional control step executes a predetermined process different from the process in the object movement control step when it is determined in the second determination step that the predetermined condition is satisfied. Here, the predetermined condition used in the first determination step and the predetermined condition used in the second determination step may be the same condition. In this case, the first determination step and the second determination step are realized by the same single process. May be. That is, the additional control step executes a predetermined process different from the process in the object movement control step when it is determined in the first determination step that the predetermined condition is satisfied. The predetermined condition used in the first determination step may be different from the predetermined condition used in the second determination step. In this case, the first determination step uses the predetermined condition used in the second determination step. It is preferable that the condition is stricter than the predetermined condition. More specifically, the predetermined condition used in the second determination step is that the first determination step uses a plurality of position coordinate information related to a series of coordinate instructions based on the history information. Satisfying a predetermined condition and further satisfying another requirement can be made a condition. More specifically, for example, the following may be performed.
The predetermined condition used in the first determination step is that a trajectory connecting a series of a plurality of designated coordinates in the detection order indicates a rotation of θ1 degree (may be 360 degrees or more, that is, it may be one rotation or more). The predetermined condition used in the determination step may indicate that a trajectory connecting a series of a plurality of designated coordinates in the detection order indicates a rotation of θ2 degrees (θ2>θ1; 360 degrees or more, that is, one rotation or more).
The predetermined condition used in the first determination step is that a trajectory connecting a series of a plurality of designated coordinates in the order of detection indicates a straight line having a length L1, and the predetermined condition used in the second judgment step is a series of a plurality of designated coordinates. May be a straight line having a length L2 (L2> L1).
The predetermined condition used in the first determination step is that a trajectory connecting a series of a plurality of designated coordinates in the detection order satisfies the predetermined condition, and the predetermined parameter is increased in accordance with the predetermined condition, and the second determination step The predetermined condition used by may be that the parameter is equal to or greater than a predetermined value.
The “predetermined process different from the object movement control” may be any process as long as the process is different from the process in the object movement control step, so that the user can execute the process different from the object movement control process. Both have the excellent effect that they can be input by coordinate instructions. The “predetermined process different from the process by the object movement control step” is preferably a process related to the object. For example, when the object is a game object, the game object is a predetermined action (an action other than movement, Perform jump action, attack action, defensive action and item use action). The process may be unrelated to the object. For example, a process for opening a menu may be executed, a pause process may be executed, or a process for saving current game progress data may be executed. It doesn't matter.

  In a third aspect based on the second aspect, the program further causes the computer to execute a coordinate instruction off detection step (S11) for detecting that the coordinate instruction by the coordinate instruction means has changed from a certain state to a non-state. In the additional control step, when the coordinate instruction OFF detection step detects that the coordinate instruction by the coordinate instruction means has changed from a certain state to a non-state, whether the predetermined condition is satisfied by the second determination step. When it is determined that the condition is satisfied, a predetermined process different from the process by the object movement control step is executed.

  In a fourth aspect based on the second aspect, when the additional control step determines that the predetermined condition is satisfied by the second determination step, the additional control step is performed for the related object related to the object controlled by the object movement control step. A predetermined process related to movement is started.

  In a fifth aspect based on the first aspect, the program causes the computer to further execute a parameter calculation step (S24) and an additional control step (S15). The parameter calculation step increases the predetermined parameter when it is determined in the first determination step that the predetermined condition is satisfied. The additional control step executes a predetermined process different from the process in the object movement control step when the parameter is equal to or greater than a predetermined value. The processing in the parameter calculation step may be as follows. That is, the first determination step repeats the determination at a predetermined timing, and the parameter calculation step increases the parameter every time the first determination step determines that the predetermined condition is satisfied, and the first determination step determines the predetermined condition. Each time it is determined that is not satisfied, the parameter may be decreased.

  In a sixth aspect based on the fifth aspect, when the parameter is greater than or equal to a predetermined value, the additional control step executes a predetermined process different from the process in the object movement control step based on the value of the parameter. . For example, the additional control step controls the movement of an object different from the object, and changes the moving speed or moving distance of the different object according to the parameter value. More specifically, as the parameter value increases, the moving speed of the object (or an increase amount of the moving speed may be increased) or the moving distance is set to be larger. Alternatively, the additional control step controls the object to perform an attack action, and sets the attack power according to the parameter value (the larger the parameter, the greater the attack power). The life force parameter of the object affected by the attack action is reduced according to the magnitude of the attack power, or the range affected by the attack action according to the magnitude of the attack power (on the basis of the object Other objects existing in the range are affected by the attack action).

  In a seventh aspect based on the first aspect, the program calculates an input speed for calculating a moving speed of the designated coordinates in the coordinate designating means regarding a plurality of designated coordinates concerning a series of coordinate instructions based on the history information. Step (S31) is further executed by the computer. Moreover, a 1st determination step determines whether the calculated moving speed is more than predetermined value. Further, the limiting step adds a predetermined limit on the movement of the object when it is determined that the moving speed is equal to or higher than a predetermined value.

  In an eighth aspect based on the first aspect, in the first determination step, the plurality of designated coordinates related to the series of coordinate instructions are connected in the order of instruction based on the plurality of designated coordinates concerning the series of coordinate instructions. It includes a rotation operation determination step for determining whether or not the locus is drawing a circular figure. The limiting step adds a predetermined limitation on the movement of the object when it is determined by the rotation operation determining step that the locus has drawn a circular figure. Here, in the eighth invention, the object movement control step gradually controls the movement of the object toward the screen position or the virtual space position corresponding to the designated coordinates by the coordinate designating means, and the rotation operation determination step comprises the object screen. It may be determined that the rotation operation is performed so as to draw an arc centered on the position.

  In a ninth aspect based on the eighth aspect, the program causes the computer to further execute a parameter addition step (S24), a parameter display step (S7), and an additional control step (S15). The parameter addition step adds a predetermined value to a parameter indicating the number of times that the condition is satisfied every time it is determined by the rotation operation determination step that a figure having a circular locus is repeatedly drawn a predetermined number of times. In the parameter display step, the parameters are displayed on the screen. The additional control step executes a predetermined process different from the process in the object movement control step when the parameter is equal to or greater than a predetermined value.

  In a tenth aspect based on the first aspect, in the first determination step, the plurality of designated coordinates relating to the series of coordinate instructions are connected in the order of instruction based on the plurality of position coordinate information concerning the series of coordinate instructions. It includes a shape drawing determination step for determining whether or not the locus has drawn a predetermined shape repeatedly for a predetermined number of times. In the restricting step, when it is determined by the shape drawing determining step that the trajectory repeats a predetermined shape for a predetermined number of times or more, a predetermined restriction is imposed on the movement of the object in the object movement control step.

  An eleventh aspect of the invention is an information processing apparatus including coordinate instruction means, object display means, object movement control means, first determination means, and movement restriction means. The coordinate instruction means is, for example, a means including a pointing device such as a mouse in addition to a touch panel and a touch screen. The object display means reads out the image data of the object and displays it on the display device. The object movement control means controls the movement of the object according to the designated coordinates by the coordinate designating means. The instruction history storage unit stores the history information of the designated coordinates by the coordinate instruction unit in the storage unit. The first determination unit determines whether or not a plurality of pieces of position coordinate information relating to the series of coordinate instructions satisfy a predetermined condition based on the history information stored by the instruction history storage unit. When the first determination unit determines that the predetermined condition is satisfied, the movement restriction unit adds a predetermined restriction on the movement of the object in the object movement control unit.

  According to the first invention, when a player operates an object, it is possible to easily perform an intention operation other than the movement of the object, and an operation in game processing or information processing using a coordinate instruction unit such as a touch panel. Can increase the sex.

  According to the second aspect of the present invention, it is possible to easily perform an intention operation other than the movement of an object in a state where a coordinate instruction is given (for example, with a finger touching the touch panel). The operability of game processing and the like can be improved.

  According to the third aspect, since the control of the related object can be started at the timing of the touch-off operation, the timing at which the additional control is started can be grasped. In addition, after the first determination step becomes affirmative, the movement of the object is restricted, and thereafter, the coordinate input process for “different processing” by the additional control step can be reliably performed.

  According to the fourth invention, an operation of moving an object other than the object controlled in the object movement control step can be executed.

  According to the fifth aspect, the additional control is started when the parameter becomes equal to or greater than a predetermined value. Thereby, it is possible to cause the player to grasp the timing for starting the additional control, and it is possible to further improve the operability.

  According to the sixth invention, since additional control is executed based on the value of the parameter, particularly in the game process, for example, a process for changing the attack speed according to the value of the parameter is possible. It becomes possible to raise.

  According to the seventh aspect, since the movement is not restricted unless the speed of the coordinate instruction is a certain speed, an operation other than the movement that is not intended by the player can be prevented. In addition, it is possible to intentionally make it easier for the player to perform operations other than movement, and it is possible to improve the operability in the processing using the coordinate instruction means.

  According to the eighth invention, the movement is restricted when the player performs an operation (rotation operation) to repeatedly draw a circular figure with a finger. Therefore, an operation other than the movement that is not intended by the player can be prevented, and the operability in the information processing using the coordinate instruction means can be improved.

  According to the ninth aspect, the parameter is increased each time a rotation operation is performed by the player's finger, and the parameter is displayed on the screen. Then, when the parameter reaches a predetermined value or more, additional control is started. As a result, the player can grasp the timing for starting the additional control, and the operability can be further improved.

  According to the tenth aspect of the present invention, movement is restricted when a coordinate instruction operation is performed such that a predetermined shape is repeatedly drawn with a finger or the like of the player. Therefore, an operation other than the movement that is not intended by the player can be prevented, and the operability in the information processing using the coordinate instruction means can be improved.

  According to the eleventh aspect, the same effect as that of the first aspect can be obtained.

  Further, the obstacle 102 is displayed on the first LCD 11, but as described above, the play field is forcibly scrolled downward. Therefore, the obstacle 102 is displayed so as to descend from the first LCD 12 to the second LCD 12 (approaching the player character 101) as time passes. That is, the obstacle 102 prevents the player character 101 from going. Therefore, in this game, in order to secure the course of the player character 101, the obstacle 102 is destroyed using the iron ball 103 and the game proceeds (if the obstacle 102 is not destroyed, The player character 101 is crushed by the obstacle 102 and the game is over). That is, in this game, the player secures the path of the player character 101 by destroying the obstacle 102 using the iron ball 103.

  Next, an operation method of the action game according to the present embodiment will be described. First, there are two main types of operations performed by the player in this game. The first is a moving operation for moving the player character 101 within the display area of the second LCD 12. The other is an attack operation for destroying the obstacle 102 with the iron ball 103. In the present embodiment, the two operations are performed by an operation using a touch panel.

  First, the moving operation will be described. The player presses the position (destination) where the player character 101 is to be moved on the play field displayed on the screen of the second LCD 12 with the stick 16 (or finger). Here, for example, it is assumed that the point 106 in FIG. 4 is pressed (note that the point 106 is shown for convenience of explanation and is not displayed on the actual game screen). In response to this, as shown in FIG. 5, the player character 101 starts moving at a predetermined speed toward the position of the point 106. And finally, as shown in FIG. 6, it will move to the position of the said point 106 (At this time, the iron ball 103 will also move so that it may be pulled by the movement of the said player character 101). During this time, the player keeps pressing the position of the point 106 with the stick 16. That is, the position where the player is touching with the stick 16 is detected every 1/60 seconds (to make the frame rate 60 fps as described above), and the player character 101 is set in advance toward that position. The movement operation by the player is realized by performing a process of moving at a predetermined speed (hereinafter, this movement speed is referred to as a normal movement speed). In other words, the player can move the player character 101 to the pressed position by continuously pressing the position to be moved with the stick 16 or the like. Also, once the touch panel 15 is pressed with the stick 16 and then the stick 16 is moved on the touch panel 15, the player follows the stick 16 (more precisely, the pressing position by the stick 16). The character 101 moves. That is, as described above, since the position touched by the player is detected every 1/60 seconds, the coordinates of the movement target destination of the player character 101 are updated every 1/60. As a result, the player character 101 moves so as to follow the movement of the stick 16. If the stick 16 is released during the movement of the player character 101, the player character 101 stops moving and stops on the spot.

  Next, the attack operation of the player character 101 will be described. In the game of the present embodiment, by continuously repeating an operation of drawing a circle with the stick 16 on the touch panel 15, the iron ball can be swung around the player character 101 as a fulcrum. Then, by touching off with the iron ball being swung, the iron ball can be thrown in front of the player character 101 and upward on the screen.

  This attack operation will be described with reference to FIGS. 7 to 11 are diagrams showing game images when the player is performing an attack operation. First, in the state of FIG. 7, the player touches a desired location on the touch panel 15, here, the position of the point 106 with the stick 16. Next, the player performs an operation of moving the stick 16 on the touch panel 15. At this time, as shown in FIG. 8, the player performs an operation so that the locus of movement of the stick 16 becomes a circle (however, it is not necessary to accurately draw a concentric circle). This corresponds to an operation of rotating the iron ball. That is, an operation of moving the stick 16 in a circular shape is performed (hereinafter, this operation is referred to as a rotation operation).

  At this time, as described above, the player character 101 tries to move at the normal moving speed toward the touched position. That is, a movement to follow the movement of the stick 16 is performed. However, the normal moving speed of the player character 101 and the speed at which the player moves the stick 16 do not necessarily match. Therefore, when the speed at which the player moves the stick 16 is significantly higher than the normal movement speed of the player character 101, the change in the coordinates of the movement target destination of the player character 101 updated every 1/60 seconds as described above. growing. As a result, as shown in FIG. 9, the player character 101 moves so as to draw a circle smaller than the circle drawn by the stick 16 around the position when the rotation operation is started.

  When the rotation operation is started, the momentum of the rotation (hereinafter simply referred to as the rotation amount) is calculated. When the rotational momentum of a certain degree or more is calculated, the charge meter 105 is raised. That is, if the rotation operation is continued with a certain degree of momentum, the charge meter 105 gradually rises (the charge meter 105 is assumed to be empty before the rotation operation is started). At this time, the moving speed of the player character 101 is decreased in accordance with the rise of the charge meter 105 (hereinafter, the decreased moving speed is referred to as a limited moving speed). Further, the iron ball 103 is moved around the player character 101 based on the rotation amount. Therefore, if the rotation operation is continued, the moving speed of the player character 101 gradually decreases as the charge meter 105 rises. As a result, as shown in FIG. 10, the player character 101 moves from a position that becomes a fulcrum of the rotating iron ball 103 (because the movement speed is reduced). Almost no movement. The charge meter 105 has an upper limit value, and if it rises to some extent, it will not rise any further. In FIG. 10, the charge meter 105 is in a state of MAX.

  As shown in FIG. 10, the charge meter 105 becomes MAX, and the player performs a touch-off operation in a state where the iron ball 103 rotates around the player character 101 as a fulcrum. Then, as shown in FIG. 11, the iron ball 103 is thrown toward the upper part of the screen, that is, the first LCD 11 (the charge meter 105 becomes empty). Then, the iron ball 103 collides with the obstacle 102, and the obstacle 102 is destroyed. Thereby, the course of the player character 101 can be secured.

  As described above, in this embodiment, when performing a rotation operation of swinging an iron ball for an attack, the player character 101 is not moved according to the touch operation as it is, but the attack operation is performed by limiting the movement. It is easy to do and enhances the operability of game play.

  Next, details of the game process executed by the game apparatus 10 will be described. First, data stored in the RAM 24 during game processing will be described. FIG. 12 is a diagram showing a memory map of the RAM 24 of the game apparatus 1. During game processing, the RAM 24 stores the touch data 241, touch history data 245, previous frame character position 246, previous frame iron ball position 247, current frame character position 248, current frame iron ball position 249, charge amount 250, charge upper limit. 251, rotation amount 252, speed limit 253, normal chain longest value 254, attack chain longest value 255, front frame iron ball movement amount 256 and the like are stored. In addition to these data, the RAM 24 stores game program and game image data read from the ROM 17 a of the memory card 17.

  The touch data 241 is data indicating a position on the touch panel 15 where an input is made by the player. In the present embodiment, the input on the touch panel is detected every 1/60 seconds (every one display frame) as described above. The touch data 241 includes an X coordinate 242, a Y coordinate 243, and a touch state flag 244. The X coordinate 242 indicates the coordinate in the X direction of the contact position on the screen of the second LCD 12 in FIG. 1, and the Y coordinate 243 indicates the coordinate in the Y direction of the contact position. The touch state flag 244 indicates a state in which the touch panel 15 is touched. The flag = “0” indicates that there is no contact. The flag = "1" indicates the start of contact. The flag = “2” indicates contact continuation.

  The touch history data 245 is a history of touch data for a predetermined display frame before the current display frame, for example, touch data for the past 60 frames. The touch history data 245 is stored by a ring buffer method, and is updated to new data in order from old data. The data structure is the same as that of the touch data 241.

  The previous frame character position 246 is data indicating the position of the player character 101 in the virtual game space in the display frame immediately before the current display frame (for example, (x, y, z) in a three-dimensional coordinate system). Expressed in the form).

  The previous frame iron ball position 247 is data indicating the position of the iron ball 103 in the virtual game space in the display frame immediately before the current display frame.

The current frame character position 248 is data indicating the position of the player character 101 in the current display frame in the virtual game space.
The current frame iron ball position 249 is data indicating the position of the iron ball 103 in the virtual display space in the current display frame. That is, a game image including the player character 101 and the iron ball 103 is generated based on the position indicated by the coordinates and displayed on the screen.

  The charge amount 250 is a value corresponding to the charge meter 105 shown in FIG. That is, it is a parameter whose value increases based on the rotation operation of the player.

  The charge upper limit 251 is a value set in advance as a value indicating the upper limit value of the charge meter 105 shown in FIG. Therefore, the charge amount 250 does not exceed the value of the charge upper limit 251.

  The rotation amount 252 is a parameter indicating the rotation amount applied to the rotation operation performed by the player. For example, in the operation of drawing a circle as shown in FIG. 8 described above, when the rotation of the circle makes one rotation, it is determined that the larger the number of rotations within a predetermined unit time, the larger the rotation amount. The amount of rotation is greater in the latter when the rotation is 5 times per second and when the rotation is 10 times per second. In other words, it is also a parameter indicating the moving amount and moving speed of the stick 16 on the touch panel 15 within a predetermined unit time when the rotating operation is performed.

  The speed limit 253 is a parameter used when the moving speed of the player character 101 is limited, and is a parameter that defines the maximum value of the above limited moving speed. In other words, the speed limit 253 indicates the upper limit of the movement amount of the player character 101 per frame. For example, the parameter is such as “5 in the X direction and 2 in the Y direction in one frame” (in this embodiment, it is treated as a velocity vector). Therefore, when the value of the speed limit 253 is small, the moving speed of the player character 101 is slow. In addition, a value smaller than the normal movement speed set in advance as a default is set as the value.

  The normal chain maximum value 254 is a value indicating the maximum value of the length of the chain 104 other than during an attack, and a predetermined value is set. Further, the longest chain value 255 at the time of attack is a value indicating the maximum value of the length of the chain 104 at the time of the attack, and a predetermined value is set.

  The previous frame iron ball movement amount 256 is a value indicating the movement amount of the iron ball 103 in the virtual game space in the display frame immediately before the current display frame.

  Next, with reference to FIGS. 13 to 20, game processing executed by the game apparatus 10 will be described. FIG. 13 is a flowchart showing the entire game process executed by the game apparatus 10. When the power of the game apparatus 10 is turned on, the CPU core 21 of the game apparatus 10 executes a startup program stored in a boot ROM (not shown), and each unit such as the RAM 24 is initialized. Then, the game program and various data stored in the memory card 17 are read into the RAM 24 via the connector 23, and the execution of the game program is started. As a result, a game image is displayed on the first LCD 11 via the first GPU 26, and a game image is displayed on the second LCD 12 via the second GPU 27, and the processing of the flowchart shown in FIG. 13 is started.

  In FIG. 13, first, a throw determination process is performed (step S1). In this process, as shown in FIG. 10 described above, it is determined whether the iron ball 103 is touched off, that is, whether the iron ball 103 is thrown (whether an attack is performed). Details of this processing will be described later.

  Next, input to the touch panel 15 is detected, and data indicating the result is stored in the RAM 24 as touch data 241 (step S2).

  Next, a charge process is performed (step S3). In this process, the player's rotation operation on the touch panel 15 as described above is detected, the rotation amount is calculated, and the charge amount 250 is added or subtracted according to the rotation amount. That is, processing related to raising the charge meter 105 by performing the rotation operation is performed. Details of this processing will be described later.

  Next, speed limit setting processing is performed (step S4). In this process, the speed limit 253 is calculated and set based on the calculation of the touch input speed (speed at which the stick 16 is moved) and the speed and the charge amount 250 with reference to the touch history. Is performed. That is, as the charge meter rises, processing related to the movement speed of the player character 101 being slowed is performed. Details of this processing will be described later.

  Next, a player character movement process is performed (step S5). In this process, a process for moving the player character 101 based on the touch data 241 and the speed limit 253 detected in step S2 is performed. Details of this processing will be described later.

  Next, an iron ball character movement process is performed (step S6). In this process, a process for moving the iron ball 103 is performed. Details will be described later.

  Next, other game processes are performed (step S7). In this processing, game processing other than the above processing, such as determination of whether the iron ball 103 collides with the obstacle 102, is performed. In addition, processing for generating and displaying an image (game image) of the virtual game space reflecting the result of the above processing is also performed.

  Next, the touch coordinates are stored in the touch history data 245 (step S8). That is, data relating to the touch input detected in step S2 is stored as touch history data 245. Next, a process of saving the position data of the player character 101 and the iron ball 103 in the process of the current frame as the position information of the previous frame is performed (step S9). Specifically, the previous frame character position 246 is updated with the current frame character position 248. Also, the previous frame iron ball position 247 is updated with the current frame iron ball position 249.

  After step S8, it is determined in step S9 whether or not the game is over (step S10). If YES, the game process is terminated, and if NO, the process returns to step S1 to repeat the game process. Thus, the game process ends.

  Next, details of the throw determination process shown in step S1 will be described. FIG. 14 is a flowchart showing details of the throw determination process shown in step S1. In FIG. 14, first, it is determined whether or not the touch panel 15 has been touched off from the touch-on state (step S11). For example, the value of the touch state flag 244 is read to determine whether it is “0” (value indicating no contact). In the case of “0”, it is further determined from the touch history data 245 whether or not the value of the touch state flag for the previous frame is “0”. As a result, when the value of the touch state flag for the previous frame is not “0”, it is determined that the touch-off is performed from the touch-on state.

  As a result of the determination in step S1, when it is determined that the touch-off is not performed (NO in step S11), the throw determination process is ended as it is. On the other hand, when it is determined that the touch-off has occurred (YES in step S11), it is subsequently determined whether or not the charge amount 250 is greater than a predetermined value (step S12). As a result of the determination, when it is determined that the value is equal to or less than the predetermined value (NO in step S12), the throw determination process is ended as it is. On the other hand, when it is determined that the charge amount 250 exceeds the predetermined value (YES in step S12), the virtual game space of the current iron ball is next displayed to indicate that the iron ball 103 is ready to be thrown. It is determined whether or not the position within the area is within the throwable area (step S13). Here, the throwable area will be described with reference to FIG. FIG. 15 is a diagram for explaining a throwable area. In FIG. 15, an area 151 shown in a fan shape in front of the player character 101 (upward on the screen) is a throwable area. At the time of touch-off, as shown in FIG. 15, when the iron ball 103 is not yet in this area (positioned behind the player character 101), the iron ball 103 is moved to the throwable area. Then, the process of moving the subsequent iron ball forward (upward on the screen), that is, the process of throwing the iron ball 103 is performed.

If the result of the determination in step S13 is that the iron ball 103 is not within the throwable area (NO in step S13), the current frame is used to move the iron ball 103 to the throwable area using the following formula: The iron ball position 249 is set to a value obtained by adding a rotation amount 252 described later to the front frame iron ball position 247 (step S14), and the process returns to the determination of step S13.
Current frame iron ball position 249 = Previous frame iron ball position 247 + Rotation amount 252

On the other hand, when it is determined that it is in the throwable position (YES in step S13), the current frame iron ball position 249 is added to the previous frame iron ball position 247 and the throwing speed Vo using the following formula. (Step S15). Here, the throwing speed Vo is a speed vector set in advance.
Current frame iron ball position 249 = Previous frame iron ball position 247 + Throwing speed Vo

Next, whether or not the linear distance between the player character 101 and the iron ball 103 in the virtual game space (that is, the length of the chain 104) is longer than the value indicated by the longest attack chain value 255. The determination is made using the following equation (step S16).
Maximum chain length at attack 255 <current frame iron ball position 249−current frame character position 248

  As a result of the determination in step S16, when the straight line distance between the player character 101 and the iron ball 103 is smaller than the longest attack chain value 255 (NO in step S16), the process returns to step S15 and the process is repeated. On the other hand, when it is determined that the straight line distance between the player character 101 and the iron ball 103 is greater than the longest attack chain value 255 (YES in step S16), the thrown iron ball 103 is pulled back to the place of the player character 101. Processing is performed (step S17). That is, it indicates that the attack has ended.

  Next, 0 is set to the charge amount 250 (step S18). That is, since the attack has ended, the charge meter 105 is emptied. This completes the throw determination process.

  Next, details of the charging process shown in step S3 will be described. FIG. 16 is a flowchart showing details of the charging process shown in step S3.

  In FIG. 16, first, the coordinates indicated by the previous frame character position 246 are converted into the screen coordinate system (step S21). That is, the screen coordinates corresponding to the previous frame character position 246 are calculated. Here, the coordinates in the previous frame are used because the coordinates in the current frame are determined in the character movement processing for the subsequent processing, and are not yet determined at this point.

  Next, the touch history data 245 is referred to, and it is detected whether or not a rotation operation around the screen coordinates calculated in step S21 has been performed. Further, the amount of rotation for the rotation operation is calculated (step S22). This is performed by the following process, for example. First, the first point (A), the second point (B), the third point (C),... Are sequentially detected. Next, a displacement angle of the line segment BC with respect to the line segment AB is obtained. Thereafter, similarly, the displacement angles of two adjacent line segments are sequentially obtained, and these are accumulated. If the cumulative displacement angle is equal to or greater than a threshold value, there is a method of recognizing that a rotation operation has been performed and using the cumulative displacement angle as a rotation amount. That is, it is a method of determining based on touch coordinates for several times. As another process, the following process can be considered. First, operation vectors having the first point and the second point (that is, the touch coordinates detected in the previous frame and the touch coordinates detected in the current frame) of the touch input detected earlier as the start point and the end point are calculated. Then, it is orthographically projected on a straight line perpendicular to the first vector having a predetermined reference point and the first point as a start point and an end point, respectively. Then, a method is conceivable in which the component vector (effective operation amount) extracted by the normal projection is used as the rotation amount. If no rotation operation is detected, 0 is set as the rotation amount. Further, it may be determined that the locus of the touch coordinates is rotated so as to draw an arc centered on the screen position (P) of the player character. For example, the touch position trajectory is centered on the screen position (P) of the player character. Alternatively, a method may be used in which an angle formed by a line segment connecting A and P and a line segment connecting B and P is obtained and the amount of rotation is calculated thereby. The above processing method is merely an example, and the present invention is not limited thereto, and any processing method may be used as long as the rotation operation and the rotation amount can be calculated.

Next, it is determined whether or not the rotation amount calculated in step S22 exceeds a predetermined threshold value (step S23). As a result of the determination, when it is determined that the rotation amount does not exceed the predetermined threshold (NO in step S23), the charge amount 250 is subtracted by a predetermined value (step S25). On the other hand, when it is determined that the value has been exceeded (YES in step S23), a predetermined value is added to the charge amount 250 (step S24). Here, as for the value to be added by the charge amount 250, a fixed value may be always added, but the amount to be added may be decreased as the charge amount 250 is increased. More specifically, a value proportional to 1 / charge amount ⁿ may be added (note that n is a natural number, the same applies in the following description). Alternatively, a value proportional to 1 / (charge amount ⁿ + fixed value) may be added. Further, the value to be added may be increased in proportion to the rotation amount.

  Next, it is determined whether or not the charge amount 250 exceeds the charge upper limit 251 (step S26). As a result of the determination, when it is determined that the value has been exceeded (YES in step S26), the value of the charge upper limit 251 is set to the charge amount 250 (step S27). That is, the charge amount 250 is adjusted so as not to exceed the charge upper limit 251. On the other hand, when it is determined that it does not exceed (NO in step S26), the process of step S27 is not performed and the charge process is terminated as it is.

  Next, details of the speed limit setting process shown in step S4 will be described. FIG. 17 is a flowchart showing details of the speed limit setting process shown in step S4. In FIG. 17, first, the moving speed of the stick 16 (hereinafter referred to as touch input speed) is calculated (step S31). The process of step S31 will be described more specifically. First, an X coordinate 242 and a Y coordinate 243 (hereinafter referred to as touch coordinates) are read from the touch data 241. Next, from the touch history data 245, the X coordinate and Y coordinate (hereinafter referred to as the previous touch coordinate) in the previous frame are read. Next, the difference between the current touch coordinates and the previous touch coordinates is calculated as a velocity vector. The calculated speed vector becomes the touch input speed.

Next, a speed limit 253 is set according to the charge amount 250 and the touch input speed calculated in step S31 (step S32). Here, it is assumed that the speed limit 253 is set to be smaller as the charge amount 250 is larger (that is, the relationship between the charge amount and the speed limit 253 is inversely proportional). Note that the setting method is not limited to this, and for example, the speed limit 253 may be set to decrease as the touch input speed increases. In addition, a value obtained by reducing a value proportional to the charge amount 250 ⁿ or a value proportional to the touch input speed ⁿ from a value (normal movement speed) set in advance as the movement speed of the player character is the speed limit 253. It may be set. A value proportional to 1 / charge amount 250 ⁿ or a value proportional to 1 / touch input speed ⁿ may be set as speed limit 253. Of course, the speed limit 253 may be set based only on the charge amount 250, or the speed limit 253 may be set based only on the touch input speed. Thus, the speed limit setting process ends.

  Next, details of the player character movement process shown in step S5 will be described. FIG. 18 is a flowchart showing details of the player character movement process shown in step S5. In FIG. 18, first, a position Tv in the virtual game space corresponding to the touch position is calculated (step S41). Specifically, the position Tv in the virtual game space corresponding to the touch position is calculated by converting the coordinate system of the touch panel into a coordinate system in the virtual game space. (As described above, in the present embodiment, the touch panel 15 uses the same resolution (detection accuracy) as the resolution of the second LCD 12, and thus the coordinates of the touch position indicate the screen coordinates as they are.)

Next, the moving speed V of the player character 101 is calculated using the following equation (step S42).
Movement speed V = coefficient c × (previous frame character position 246−virtual game space position Tv corresponding to the touch position)
Here, the coefficient c is a positive number of 1 or less. The moving speed V is calculated as a speed vector, for example.

  Next, it is determined whether or not the calculated moving speed V exceeds the speed limit 253 (step S43). As a result of the determination, when it is determined that the speed limit 253 is not exceeded (NO in step S43), the process proceeds to the process of step S45 as it is. On the other hand, when it is determined that the speed limit 253 is exceeded (YES in step S43), the speed limit 253 is set to the moving speed V (step S44).

Next, the current frame character position 248 is set using the following equation (step S45).
Current frame character position 248 = previous frame character position 246 + movement speed V
As a result, the position of the player character 101 displayed in the current frame is determined. This is the end of the player character movement process.

  Next, details of the iron ball movement process shown in step S6 will be described. FIG. 19 is a flowchart showing details of the iron ball moving process shown in step S6. FIG. 20 illustrates the process of moving the iron ball 103. In FIG. 19, first, a process of moving the position of the iron ball 103 by the same movement amount as the previous iron ball movement amount is performed (step S51). This process corresponds to the arrow 201 in FIG.

  Next, a process of moving the iron ball 103 by a distance corresponding to the amount of rotation is performed in a direction perpendicular to the direction connecting the iron ball 103 from the player character 101 (step S52). This process corresponds to the arrow 202 shown in FIG.

  Next, it is determined whether or not the linear distance between the player character 101 and the iron ball 103 is larger than the normal chain longest value 254 (step S53). As a result of the determination, when the linear distance between the player character 101 and the iron ball 103 is larger than the normal chain maximum value 254 (YES in step S53), the linear distance between the player character 101 and the iron ball 103 is Processing is performed in which the position of the iron ball 103 is brought close to the player character 101 so that the normal chain maximum value 254 is obtained (step S54). This process corresponds to the arrow 203 in FIG. Then, the current frame iron ball position 249 is updated at the position after the approach. On the other hand, as a result of the determination in step S53, if the linear distance between the player character 101 and the iron ball 103 is equal to or smaller than the normal chain maximum value 254 (NO in step S53), the process in step S54 is not performed, The current frame iron ball position 249 is updated at the position moved in step S52. Then, the process proceeds to the next step S55.

  Next, the difference between the current frame iron ball position 249 and the previous frame iron ball position 247 is calculated and stored as the previous frame iron ball movement amount 256 (step S55). This is for use in the process of step S51 in the process in the next frame. Thus, the iron ball movement process ends.

  As described above, in the present embodiment, the moving speed of the player character 101 is reduced when the rotation operation is vigorous (the rotation amount is a certain level or more). Thereby, it becomes easy to perform operations other than the movement of the player character, such as throwing an iron ball as described above, and the operability can be improved. Moreover, it is also possible to achieve both different operations without degrading the operability of the moving operation performed by the touch operation on the touch panel and the operation other than the moving operation. In other words, when you want to move the player character in a circle, move it slowly with a stick 16, and when you want to attack (ironball throwing), draw a circle many times. The stick 16 can be moved.

  In regard to the throw determination in step S1 of FIG. 13 described above, instead of the touch-off determination (step S11) that is the determination of attack start as described above, the touch history data 245 is referred to for the past predetermined number of frames. The attack start may be determined by calculating the input trajectory and determining whether the input trajectory draws a predetermined trajectory. For example, when it is determined that the input locus has drawn a triangle, the same processing as when the touch-off is performed may be performed. In addition, regarding the timing for determining whether or not such a predetermined figure has been drawn, it may be determined whether or not a predetermined locus has been drawn when touched off, or before touch-off. Alternatively, it may be determined whether a predetermined locus has been drawn. That is, even when the touch-off is performed, the attack may not be started (the iron ball is not thrown) if the input locus does not draw a predetermined locus. Alternatively, an attack may be started if a predetermined locus is drawn even before touch-off.

  Further, as the processing content at the time of touch-off, in the above-described embodiment, the processing of throwing an iron ball is performed. The content to be processed is not limited to this. For example, a process of jumping the player character 101 may be performed, or a defensive action (for example, holding a shield) of the player character 101 may be performed. Also good. Further, the parameters (attack power, moving speed, etc.) of the player character 101 may be temporarily changed. In any case, when performing an operation other than the movement of the player character 101, the movement speed of the player character 101 can be reduced so that the player character 101 does not move around unnecessarily. During the movement, it is possible to prevent the player character 101 from moving too much to an unintended position and improve operability.

  Further, with regard to the character movement process in step S5, when the charge amount 250 is greater than or equal to a predetermined value, a process that does not move the player character 101 may be performed. In this case, for example, if the charge amount is MAX, the position of the player character 101 is fixed, so that the operability can be further improved.

In addition, regarding the process of step S15 described with reference to FIG. 14, in the above-described embodiment, the position of the iron ball is calculated with the throwing speed Vo as a fixed value. However, the throwing speed Vo is not limited to a fixed value, and may be calculated so as to change according to the charge amount. In this case, even if the charge meter 105 shown in FIG. 10 or the like has not accumulated up to MAX, the threshold value determined in step S12 is set to MAX of the charge meter 105 so that an iron ball is thrown at the time of touch-off. Set to a value smaller than the corresponding value. Then, a value calculated using the following equation may be used as the throwing speed Vo.
Throwing speed Vo = coefficient c × ((charge amount 250) − (threshold)) + constant A
Here, the constant A is a value set in advance as the minimum throwing speed. The threshold value is the same as the threshold value used in step S12 in FIG. 14, and is a value stored in advance in a program or the like. By processing in this way, it is possible to change the throwing speed Vo according to the charge amount, and it is possible to increase the reality of the game and increase the fun of the game.

  Further, whether or not the rotation amount for the process of step S23 in FIG. 16 has exceeded a predetermined threshold value may be determined not only by the rotation amount but also by whether or not the touch speed has exceeded a predetermined threshold value. good. Furthermore, the determination may be made based on both the rotation amount and the touch speed. As a result, the amount of rotation can be detected more accurately, and erroneous operation can be prevented.

  In addition, for the operation of swinging the iron ball 103 (see FIG. 10), which is the premise of the process of throwing the iron ball 103 as described above, a flag “rotation mode” is provided to indicate that the ball is being swung. The data may be stored in the RAM 24. In other words, the processing may be such that “rotation mode” is set to ON when a rotation operation at a predetermined speed or more is performed, and OFF is set otherwise. When this “rotation mode” flag is used, the speed limit setting process in step S4 in FIG. 13 and the player character movement process in step S5 may be performed as described below.

  FIG. 21 is a flowchart showing the speed limit setting process when the “rotation mode” flag is used. In FIG. 21, first, the process of step S31 as described above is performed. That is, the touch history data 245 is referred to, and the touch input speed is calculated based on the touch data for the past several frames.

  Next, it is determined whether or not the calculated touch input speed is equal to or higher than a predetermined value (step S61). As a result, when it is determined that the touch input speed is equal to or higher than the predetermined value (YES in step S61), the “rotation mode” flag is set to ON (step S62). Subsequently, the process of step S32 described above is performed. That is, the speed limit 253 is set according to the charge amount 250 and the touch input speed. Then, the speed limit setting process ends. On the other hand, if the result of determination in step S61 is that the touch input speed is determined to be less than the predetermined value (NO in step S61), the “rotation mode” flag is set to off (step S63), and the speed limit setting process ends. To do.

Next, the player character movement process when the “rotation mode” flag is used will be described. FIG. 22 is a flowchart showing the player character movement process when the “rotation mode” flag is used. In FIG. 22, first, the process of step S41 described above is performed. That is, the virtual game space position Tv corresponding to the touch position is calculated. Next, the process of step S42 mentioned above is performed. That is, the moving speed of the player character 101 is calculated using the following equation.
Movement speed V = coefficient c × (previous character position−virtual game space position Tv corresponding to the touch position)

Next, it is determined whether or not the “rotation mode” flag is set to ON (step S71). As a result of the determination, when the “rotation mode” flag is set to ON (YES in step S71), in order to decrease the moving speed of the player character 101, the moving speed V calculated in the above step S42 is used. Then, a correction process is performed using the following equation (step S72).
V = V × second coefficient c2
Here, unlike the coefficient c used in step S42, the second coefficient c2 is a positive number less than 1. For this reason, the value of V calculated in step S72 is smaller than the value of V calculated in step S42, that is, the moving speed is reduced. Next, the “rotation mode” flag is set to OFF (step S73). And the process after step S43 as mentioned above is performed.

  On the other hand, as a result of the determination in step S71, when the “rotation mode” flag is not set to ON (NO in step S71), the processing from step S43 as described above is performed as it is. This completes the player character movement process when the “rotation mode” flag is used.

  Thus, even if the process is performed using the “rotation mode” flag, the same effect as described above can be obtained.
