Description

  The present invention relates to a game program, a game apparatus, and a game method for executing a game that virtually acts on a moving object that moves in a game space.

  Conventionally, a baseball game is known in which a ball object is hit by aligning the center portion of the meat cursor with the arrival position of the ball object moving in the game space and pressing the controller's push button (for example, Patent Documents). 1). In such a baseball game, the player moves the meet cursor by operating, for example, a cross key of the controller.

  By the way, in recent years, a mobile phone (for example, i-phone (registered trademark)) that includes a touch panel type display unit and can execute a game has become widespread.

  In such a mobile phone, the user can perform all operations by touching the touch panel. Therefore, it is not necessary to provide physical buttons such as a numeric keypad on the mobile phone, and a simple appearance is realized. In addition, the mobile phone is basically operated by tracing the touch panel with a finger or touching it lightly with a finger. In other words, since a tracing operation is newly added in addition to the pressing operation, a novel user interface is realized as compared with the conventional mobile phone which is based on the pressing operation.

Japanese Patent No. 3892889

  However, since the game of Patent Document 1 is premised on the use of a controller having a cross key, a push button, etc., the characteristics of the user interface of a mobile phone having a touch panel display unit based on finger operation are described. It cannot be fully utilized. Therefore, in the method of Patent Document 1, the operation of tracing, which is a characteristic operation of this type of mobile phone, is not utilized at all.

  An object of the present invention is to provide a game control program for realizing a game capable of virtually acting on a moving object moving in a game space by utilizing a user interface of a portable terminal having a touch panel display unit It is to be.

  (1) A game apparatus according to an aspect of the present invention is a game apparatus that controls the progress of a game that virtually acts on a moving object that moves in a game space, and includes a touch panel display unit. Trajectory acquisition for acquiring a trajectory in which the player actually moves the finger in contact based on an operation instruction from the player that moves the finger in contact with the operating means and draws a predetermined closed loop on the display screen of the display unit Means, and when the closed loop trajectory is acquired by the trajectory acquiring means within a predetermined time, an aiming cursor generating means for generating an aiming cursor having a shape corresponding to the acquired trajectory, and after generation of the aiming cursor When the remaining time is within the predetermined time, the aiming cursor is moved forward based on the operation instruction from the player input to the operation means. When a moving means for moving and displaying on the display unit and an operation instruction for determining a timing for giving a virtual action to the moving object are input, a timing signal output from the operating means is acquired. When at least a part of the moving object and the aiming cursor overlap when the timing acquisition means and the timing acquisition means acquire the timing signal, a virtual action is applied to the moving object. Action imparting means.

  A game control program according to another aspect of the present invention is a game control program that causes a computer to function as a game device that controls the progress of a game that virtually acts on a moving object that moves in a game space. The game apparatus includes an operation unit including a touch panel type display unit, and on the display screen of the display unit, based on an operation instruction from a player that moves a finger so as to draw a predetermined closed loop, A trajectory acquisition unit that acquires a trajectory in which the player has actually moved a finger, and an aiming having a shape corresponding to the acquired trajectory when the trajectory acquisition unit acquires the trajectory of the closed loop within a predetermined time. An aiming cursor generating means for generating a cursor, and a remaining time after generation of the aiming cursor and at the predetermined time A moving means for moving and displaying the aiming cursor on the display unit based on an operation instruction from the player input to the operating means, and a timing for giving a virtual action to the moving object. When an operation instruction for determining is input, a timing acquisition unit that acquires a timing signal output from the operation unit; and when the timing acquisition unit acquires the timing signal, the moving object and the When at least a part of the aiming cursor overlaps, the computer is caused to function as an action imparting unit that virtually acts on the moving object.

  A game control method according to yet another aspect of the present invention is a game control method in which a game device controls the progress of a game that virtually acts on a moving object that moves in a game space, The game apparatus includes an operation unit including a touch panel display unit, and the game apparatus is based on an operation instruction from a player that moves a finger in a predetermined closed loop on the display screen of the display unit. A trajectory acquisition step of acquiring a trajectory in which the player actually moves the finger, and a trajectory acquired when the game apparatus acquires the closed-loop trajectory by the trajectory acquisition step within a predetermined time. An aiming cursor generating step for generating an aiming cursor having a shape corresponding to the shape, and the game device after the aiming cursor is generated, A moving step of moving the aiming cursor in the game space based on an operation instruction from the player input in the operation step when there is a remaining time in the predetermined time; and A timing acquisition step of acquiring a timing signal output from the operation means when an operation instruction for determining a timing at which a virtual action is applied to an object is input; and the game device acquires the timing When the timing signal is acquired by a step, when at least a part of the moving object and the aiming cursor overlap, there is provided an action applying step that virtually acts on the moving object. Yes.

  According to these configurations, when the player gives an operation instruction to move the finger in a predetermined closed loop on the display screen of the display unit, the player actually touches the finger based on the operation instruction. The moved locus is acquired, and an aiming cursor having a shape corresponding to the locus is generated and displayed on the display unit. The player moves the aiming cursor in the game space by operating the operation means. Then, when an operation instruction for determining the timing at which an action is applied to the moving object is input by the player, a timing signal is output from the operation means and acquired by the timing acquisition means. If the moving object and the aiming cursor overlap when the timing signal is acquired, an action is given to the moving object.

  In other words, in order to display the aiming cursor on the display screen, the player moves his / her finger on the display screen so that the generated aiming cursor acts on the moving object. A new operation will be performed. Moreover, since the generation of the aiming cursor and the subsequent movement of the aiming cursor need to be performed within a limited time, the player is also required to have a strategy for how to allocate the time. This makes it possible to fully exploit the features of the game device including the display unit, and to realize a game having unprecedented interest.

  The aiming cursor may be moved by, for example, incorporating a gyro sensor in the game device and moving the aiming cursor by tilting the entire game device. That is, the finger is moved without touching the aiming cursor for the following reason.

  In other words, since the aiming cursor must finally be placed on the moving object, it is necessary to clearly grasp the positional relationship with the moving object that gradually approaches, but if the aiming cursor is moved with the finger of the player This is because it is assumed that the finger itself gets in the way and makes it difficult to see the positional relationship between them.

  For example, when the above configuration is applied to a baseball game, the area of the aiming cursor corresponding to the meet cursor in the conventional game increases as the area of the closed loop drawn by the trajectory when the player moves his / her finger in contact increases. The body object, that is, the ball object can be easily brought into contact with the aiming object.

  However, since it takes time to draw a large aiming cursor, the remaining time of the predetermined time is shortened, and as a result, the time for performing movement adjustment for placing the aiming cursor on the ball object is limited. . In an extreme case, a predetermined time is consumed simply by drawing the aiming cursor, and there may be no time for moving the aiming cursor. Conversely, when drawing a small aiming cursor, the contact area with the ball object is small, but the time required to draw the trajectory is short, so the remaining time of the predetermined time is also long, and the aiming cursor is placed on the ball object. There is a margin in the time for performing the movement adjustment.

  In other words, the size of the aiming cursor and the time to move the created aiming cursor are in a trade-off relationship, so that the player can select his / her favorite operation or obtain time Since it is necessary to consider allocation and various strategies, it is possible to provide a baseball game with unprecedented interest.

  (2) The predetermined time is an event period from an event start time set based on a movement start time of the moving object to an event end time at which the moving object ends moving, and the timing acquisition unit Preferably, the timing signal is acquired after the generation of the aiming cursor and when there is a remaining time in the event period.

  According to this configuration, the event period is set from the event start time set on the basis of the movement start time of the moving object to the event end time at which the moving object ends moving. Then, during the event period, the player is required to perform an operation of moving his / her finger on the display screen and an operation of moving the aiming cursor and overlapping the moving object.

  Specifically, if this configuration is applied to, for example, a baseball game, the time from when the pitcher is thrown (event start) until the pitched ball passes over the home base (event end) This is the time (event time) allowed for drawing the aiming cursor.

  Therefore, if the player tries to draw a large aiming object in order to widen the area that hits the ball, the time spent for finger contact movement increases, and as a result, the remaining time of the event period decreases, so the movement of the aiming object The time that can be spent on (position adjustment to match the flying ball) is reduced.

  Therefore, the player sets the area of the closed loop in consideration of the remaining time of the event period, and can realize a game having an unprecedented interest.

  (3) It is preferable that the moving means decreases the moving speed of the aiming cursor as the area of the aiming cursor increases.

  According to this configuration, it is possible to set a virtual movement tendency that the movement is slower as the area is larger. For example, when this configuration is applied to a baseball game, if the meat cursor (aiming cursor) that is the hitting range is set large for the ball object thrown from the pitcher, the area where the ball object and the meat cursor overlap is wide. On the other hand, since the moving speed for adjusting the position of the meet cursor becomes slow, it becomes difficult to move the meet cursor quickly in accordance with, for example, a changing ball. Conversely, if the meet cursor is set to be small, the hitting range is reduced, but the moving speed is increased, so that the meet cursor can be quickly moved with respect to the changing ball.

  Therefore, the player can generate an aiming cursor of a desired size from the balance of the area of the aiming cursor and the moving speed, can increase variations in operations and strategies, and enhance the interest of the game. Can do.

  (4) It further comprises level setting means for setting the level of the player based on the operation instruction of the player, and the aiming cursor generation means is a case where the trajectory where the player touches the finger is not in a closed loop. Preferably, the aiming cursor is generated when the distance between the start point and the end point of the trajectory is smaller than a predetermined distance that is predetermined according to the level set by the level setting means.

  According to this configuration, the distance between the start point and the end point of the trajectory is determined in advance according to the level set by the player, even when the closed loop cannot be drawn as a result of the player moving his / her finger. If it is smaller than the specified distance, an aiming cursor is generated.

  For example, when this configuration is applied to a baseball game, the start point and end point of a meet cursor (aiming cursor) that is a hitting range are not connected to a ball thrown from a pitcher, and a gap is generated between the two points. Even if it is, the meet cursor is regarded as completed according to the level set by the player.

  Therefore, for example, if the level is set low by the level setting means, even a beginner or a player who wants to play the game easily can enjoy the game, and the difficulty level of the game depends on the skill level of the player's game. Can be changed, and the fun of the game can be further enhanced.

  (5) The action applying means may increase the distance between the start point and the end point of the trajectory when the aiming cursor is generated even when the trajectory where the player moves the finger in contact is not in a closed loop. Indeed, it is preferable to reduce the power when acting on the moving object.

  According to this configuration, a penalty can be imposed on the player when a closed loop cannot be drawn.

  For example, consider the case where this configuration is applied to a baseball game. In (4) above, even if a gap occurs in the aiming cursor (meet cursor), it is considered that the aiming cursor is completed according to the level. As the gap increases, the hitting force on the ball object can be set to be small, for example, the flying distance of the hit ball decreases, and a penalty can be given to the player.

  (6) When the locus is in a closed loop, the aiming cursor generation unit removes a locus section between the intersection of the locus and the start point of the locus and a locus section between the intersection and the end point of the locus. The aiming cursor is preferably generated.

  According to this configuration, when the trajectory drawn by moving the finger in contact with the player is in a closed loop, the trajectory section between the trajectory intersection and the trajectory start point and the trajectory section between the intersection and the trajectory end point are Removed and an aiming cursor is generated. Therefore, the aesthetics of the aiming cursor can be improved.

  (7) The action imparting means increases power when acting on the moving object as the lengths of the trajectory section between the intersection and the start point and the trajectory section between the intersection and the end point increase. It is preferable to set a small value.

  According to this configuration, as the length of the trajectory section between the intersection and the start point of the trajectory and the trajectory section between the intersection and the end point increases, the player cannot accurately draw the closed loop. Can be penalized.

  For example, when this configuration is applied to a baseball game, if only the intersection has to be formed for drawing the meet cursor (aiming cursor), the beard extends from the intersection rather than accurately matching the start point and the end point. Drawing the above-described trajectory section makes it possible to draw a closed loop easily and quickly, which is advantageous to the player.

  However, if the evaluation is the same for the case where the locus section is drawn and the case where it is not drawn, an unfair feeling will occur. Therefore, it is possible to increase the interest of the game by setting the ball striking force to be smaller, such as the longer the trajectory section, the shorter the hit distance, and imposing a penalty on the player.

  (8) It is preferable that the action applying unit sets a power for applying an action to the moving object as the shape of the track acquired by the track acquiring unit moves away from a predetermined reference shape.

  According to this configuration, as the shape of the trajectory drawn by touching and moving the finger by the player moves away from the predetermined reference shape, the player is not able to draw the closed loop accurately. Can be imposed.

  In the above (7), if the meet cursor (aiming cursor) only needs to be a closed loop, it is advantageous for the player to draw quickly even if the shape is distorted. However, if the evaluation is the same for the case where the closed loop is accurately drawn and the case where the closed loop is not drawn, an unfair feeling will occur. Therefore, in order to differentiate between the case where the closed loop is accurately drawn and the case where it is not drawn, a penalty such as reducing the hitting force against the ball object, such as the distance of hitting the ball, the farther away from the reference shape, the lower the hitting distance. By imposing on the player, it is possible to enhance the interest of the game.

  (9) When the trajectory acquired by the trajectory acquisition unit is a closed loop, the action applying unit sets a larger power for applying the action to the moving object as the area in the closed loop decreases. It is preferable to do.

  According to this configuration, even when the closed loop area is reduced and it is difficult to pass the moving object through the aiming cursor, the power acting on the moving object is increased accordingly. The advantage in this case can be imposed on the player.

  (10) The action imparting means acts on the moving object as the passing position of the moving object with respect to the aiming cursor is closer to the center of gravity of the aiming cursor when the timing obtaining means obtains the timing signal. It is preferable to set the power at the time of giving a large value.

  According to this configuration, as the passing position of the moving object in the aiming object is closer to the center of gravity of the aiming cursor, the moving object can be acted with higher power. Therefore, the player is motivated to move the aiming cursor so that the moving object passes through the center of gravity of the aiming cursor, and the game can be more interesting.

  (11) It is preferable that the aiming cursor generating unit generates the aiming cursor so that a contour line becomes thicker when a time required for the player to draw a closed loop is longer than a predetermined time.

  According to this configuration, when the player draws a closed loop over time, the outline of the aiming cursor is thickened. For this reason, the area of the aiming cursor is increased, and a merit can be given to the player. For example, when the above configuration is applied to a baseball game, drawing a closed loop over time to generate a meet cursor (aiming cursor) causes the ball object to fly in the meantime. The movement adjustment time after completion is limited, which is disadvantageous for the player.

  Therefore, if a merit that the area of the aiming cursor is increased is provided, an element advantageous to the player is given to the hitting itself. As a result, various options are given to the player, and variations of operations and strategies can be increased, and the fun of the game can be enhanced.

  Note that the timing at which the outline becomes thick may be the time when the closed loop is completed. In other words, if the time until the closed loop is completed is measured, and if this time exceeds a predetermined reference time, it is considered that the player has drawn over time and the entire contour line is made thicker. Good.

  (12) It is preferable that the aiming cursor generation unit does not generate the aiming cursor when the trajectory protrudes from a predetermined maximum area where the player can draw the closed loop on the display screen of the display unit.

  According to this configuration, since the player is restricted to move his / her finger within a predetermined maximum area on the display screen, it is possible to give the player a sense of tension. Can be increased. Further, it is possible to prevent the difficulty of the game from being reduced due to an excessive increase in the area of the aiming cursor.

  (13) Character data storage means for storing information on a plurality of characters that give a virtual action to the moving object is further provided, and the information on the characters is set individually for each character in advance. Preferably, the trajectory acquisition means displays the maximum area on a display screen before an operation instruction from a player who draws a closed loop is included.

  According to this configuration, since the maximum region where a closed loop can be drawn is displayed, it is possible to avoid a situation where a large closed loop is drawn in a dark cloud. More specifically, for example, depending on the player, there is a possibility of not thinking about moving the drawn aiming cursor, but just thinking about drawing a large aiming cursor and hitting it on the ball object. In addition, the original game features are not utilized, and, for example, when the players compare the battle results, the game conditions greatly change and unfairness also arises. Therefore, by adopting the above-described configuration, it is possible to secure basic game characteristics in which an aiming cursor is drawn, moved, and applied to the ball object. In addition, according to this configuration, the maximum area in which a closed loop can be drawn differs for each character (for example, a batter character), so that the player can grasp in advance the character's batting ability (the range in which the ball can be returned) and have an interest in the game. improves.

  (14) It is preferable that the maximum area is displayed in a translucent manner and is erased when the player touches the display screen.

  According to this configuration, the maximum area of the closed loop can be easily identified from the game configuration screen and does not interfere with the game screen itself. Further, since the player erases at the moment of contact to draw a closed loop, it is possible to eliminate an easy player operation such that the maximum closed loop can be drawn by simply tracing it.

  According to the present invention, it is possible to make full use of the characteristics of a game device including a touch panel display unit, and at the same time, it is possible to realize a game having unprecedented interest.

  Hereinafter, a game device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of a game device according to an embodiment of the present invention. In the present embodiment, for example, a mobile phone including a touch panel display unit is employed as the game apparatus. However, this is only an example, and a portable terminal having a touch panel display such as a PDA (Personal Data Assistance) may be adopted, or a portable game device having a touch panel display may be adopted. Good.

  In the present embodiment, a ball object BL1 (an example of a moving object) that moves in the game space as a game is positioned by an aiming cursor (corresponding to a conventional game meet cursor, which will be described below as an aiming cursor). Adopting a baseball game that virtually strikes back.

  1 includes a gyro sensor 1, a CPU (Central Processing Unit) 2, a communication control circuit 3, a RAM (Random Access Memory) 4, a ROM (Read-Only Memory) 5, a sound processing circuit 6, and an image processing circuit. 7, a monitor 8, a speaker 61, and a microphone 62. The blocks such as the gyro sensor 1 to the image processing circuit 7 shown in FIG. 1 are connected to each other via a bus line BS.

  The gyro sensor 1 is composed of, for example, a gyro sensor that can detect the attitude of the game apparatus in the roll direction and the attitude with respect to the pitch direction, and detects angular velocities in the roll direction and the pitch direction and outputs an angular velocity signal.

  The CPU 2 interprets instructions from the game control program stored in the ROM 5 and performs various data processing and control. The communication control circuit 3 spreads the transmission target data generated by the CPU 2 using, for example, CDMA (Code Division Multiple Access) or the like, and then performs QAM (Quadrature Amplitude phase Modulation), PSK (Phase Shift Keying), QPSK (Quadrature). A process of modulating and transmitting by (Phase Shift Keying) or the like, a process of demodulating the received data, a despreading process, and a process of outputting the obtained data to the CPU 2 are performed.

  The RAM 4 secures a work area for the CPU 2. The ROM 5 stores programs and the like necessary for basic control (for example, startup control) of the game device.

  The sound processing circuit 6 generates an analog audio signal corresponding to the sound generation instruction from the CPU 2 and outputs it to the speaker 61. The image processing circuit 7 controls the monitor 8 in accordance with a drawing instruction from the CPU 11 and displays a predetermined image on the monitor 8. The microphone 62 converts the sound from the player into an electric signal.

  The image processing circuit 7 includes a touch input detection circuit 9 and displays various images on the monitor 8. The touch input detection circuit 9 outputs the coordinate data of the contact position to the CPU 2 and makes the CPU 2 recognize the contact position when an instruction means such as a touch pen or a player's finger is directly touched to the monitor 8.

  Further, the touch input detection circuit 9 outputs the coordinate data of the object to the CPU 2 when the pointing means is directly touched at the position of the object displayed on the monitor 8, and the object is touched. Is recognized by the CPU 2.

  The monitor 8 includes, for example, a liquid crystal panel and a touch pad attached on the display surface of the liquid crystal panel. As the touch pad, for example, a capacitive type or a resistive film type is adopted. As the liquid crystal panel, for example, a liquid crystal panel such as TFT (Thin Film Transistor) or STN (Super Twisted Nematic) is used, and for example, 4096 colors can be displayed. Note that an organic EL (Electro Luminescence) panel or the like may be employed instead of the liquid crystal panel.

  FIG. 2 shows a functional block diagram of the game apparatus shown in FIG. As shown in FIG. 2, the game device includes an operation display unit 10, a program execution unit 20, and a storage unit 30.

  The operation display unit 10 includes the gyro sensor 1, the touch input detection circuit 9, the monitor 8, and the like shown in FIG. 1, and receives various operation instructions input by the player and displays various game images.

  Specifically, in order to generate the aiming cursor, the operation display unit 10 receives an operation instruction for causing the player to touch and move the finger so as to draw a predetermined closed loop on the display screen of the operation display unit 10.

  Therefore, the operation display unit 10 outputs coordinate data that is two-dimensional data indicating the position on the display screen touched by the player. Here, the operation display unit 10 outputs coordinate data at regular time intervals when the player is touching the operation screen with a finger. In addition, the time interval at which the coordinate data is output is significantly shorter than the time required for the player to move the finger between adjacent coordinates on the touch pad.

  In the present embodiment, a circle is employed as the predetermined closed loop, but this is merely an example, and a figure other than a circle such as an ellipse or a polygon may be employed.

  Further, the operation display unit 10 receives a batting instruction input by the player in order to determine the batting timing of the ball object moving in the game space. Specifically, the operation display unit 10 displays a batting instruction button (not shown) under an instruction from the program execution unit 20, and accepts the batting instruction by causing the player to touch the batting instruction button. When the operation display unit 10 receives a batting instruction from the player, the operation display unit 10 outputs a timing signal.

  In addition, the operation display unit 10 receives a movement instruction input by the player in order to move the aiming cursor on the display screen. Here, the player inputs a movement instruction by tilting the game apparatus itself without touching the aiming cursor. Therefore, the operation display unit 10 receives a movement instruction from the player by causing the gyro sensor 1 to detect whether or not the game apparatus is tilted.

The reason why the aiming cursor movement instruction is performed without contact as described above is as follows.
In other words, the aiming cursor needs to be finally applied to the ball object, so it is necessary to clearly grasp the positional relationship with the gradually approaching ball object, but if the aiming cursor is moved with the player's finger This is because it is assumed that the finger itself becomes an obstacle and it is difficult to see the positional relationship between the two.

  FIG. 3 is a diagram showing an example of a baseball game image displayed on the display screen of the operation display unit 10. As shown in FIG. 3, this baseball game is a baseball game in which the pitcher character CL2 throws the ball object BL1 and the batter character CL1 returns the ball object BL1 with the bat object BT.

  Here, the player touches and moves the finger so as to draw a circle on the display screen of the operation display unit 10 to generate the aiming cursor K1. Then, the player tilts the operation display unit 10 to move the aiming cursor K1. When the ball object BL1 reaches the vicinity of the home base, the player positions the aiming cursor K1 on the ball object BL1 and inputs a batting instruction. To do. Then, the bat object BT is displayed as a swing, and the ball object BL1 is hit back.

  Returning to FIG. 2, the program execution unit 20 is mainly configured by the CPU 2, and includes a trajectory acquisition unit 21, an aiming cursor generation unit 22, a cursor movement unit 23, a timing acquisition unit 24, an action addition unit 25, and a level setting unit 26. It has a function. These functions are realized by the CPU 2 executing a game control program.

  The trajectory acquisition unit 21 recognizes the position on the display screen touched by the player from the coordinate data output from the operation display unit 10, and tracks the position, thereby tracking the finger touched on the display screen by the player. Get the trajectory.

  Specifically, when the coordinate data is output from the operation display unit 10 at regular time intervals and the position indicated by the coordinate data is changed, the trajectory acquisition unit 21 determines that the player is moving the finger in contact. to decide.

  On the other hand, the trajectory acquisition unit 21 outputs coordinate data from the operation display unit 10 at a constant time interval. However, when the position indicated by the coordinate data has not changed for a certain period of time, or the finger moves from the display screen. When the coordinate data is not output after being released, it is determined that the player has finished the operation of moving the finger in contact.

  When the trajectory acquisition unit 21 determines that the player is moving the finger in contact, the trajectory acquisition unit 21 specifies the position indicated by the coordinate data output first in the series of coordinate data as the start point of the trajectory, and finally outputs it. The position indicated by the coordinate data is specified as the end point of the trajectory, and the display indicated by a series of coordinate data output at regular time intervals from when the coordinate data of the start point is output until the coordinate data of the end point is output A line drawn by each dot on the screen is acquired as a locus.

  In addition, the trajectory acquisition unit 21 displays a semi-transparent and circular maximum region MD that can draw a closed loop serving as the aiming cursor K1 in the approximate center of the operation display unit 10 before the player touches the finger. Displayed above (see FIG. 3).

  Here, the size of the maximum area MD is individually set according to the batting ability of the batter character CL1. That is, the maximum area MD is displayed larger as the batting ability of the batter character CL1 is higher.

  However, it is desirable that the maximum area MD does not exceed the range obtained by dividing the strike zone into four, for example. This is because if the aiming cursor is too large, the aiming cursor K1 is easily displayed with the large range as a target, and in order to avoid a strike, the game object is simply played by hitting the bat object BT against the ball object BL1. This is to avoid becoming.

  As a result, the player draws a closed loop after visually recognizing the maximum area MD displayed in advance. When the size of the closed loop exceeds the maximum area, the aiming cursor K1 is Not generated. In this case, the batter character CL1 will see off regardless of whether or not the ball object BL1 is a strike. Therefore, the player is requested to generate the aiming cursor K1 with the maximum area MD as an upper limit.

  The displayed maximum area MD is deleted when the player touches the display screen with a finger. This is to eliminate an easy player operation in which the maximum closed loop can be drawn by simply tracing it.

  In FIG. 3, the aiming cursor K1 and the maximum area MD are displayed at the same time for convenience of explanation. Actually, the maximum area MD is deleted when the player touches the display screen with a finger. Therefore, they are not displayed at the same time.

  The aiming cursor generation unit 22 generates an aiming cursor K1 having a shape corresponding to the trajectory acquired by the trajectory acquisition unit 21 within a predetermined time. Here, as the predetermined time, an event period from an event start time set on the basis of the movement start time of the ball object BL1 to an event end time when the ball object BL1 passes on the home base can be adopted.

  As the event start time, for example, a time at which the pitcher character CL2 performs a motion to throw the ball object BL1, that is, a time slightly before the movement start time of the ball object BL1 can be used. However, this is an example, and the movement start time of the ball object BL1 may be adopted as the event start time. The event end time is set as the timing at which the ball object BL1 passes on the home base because no hitting can occur thereafter.

  In addition, the aiming cursor generation unit 22 does not generate the aiming cursor K1 when the locus protrudes from the maximum area MD.

  This imposes a restriction that the player must move his / her finger within the maximum area MD, thereby enhancing the interest of the game. Further, it can be prevented that the area of the aiming cursor K1 becomes excessively large and the ball object BL1 is easy to hit and the difficulty level of the game is extremely lowered.

  Returning to FIG. 2, when the locus acquired by the locus acquisition unit 21 is not in a closed loop, the aiming cursor generation unit 22 changes the locus ZL from the start point SP to the end point EP as shown in FIG. Basically, the aiming cursor K1 is not generated when there is no intersection. FIG. 4A is a diagram illustrating an example of a trajectory ZL that is not a closed loop, and FIG. 4B is a diagram illustrating an example of a trajectory ZL that is a closed loop.

  On the other hand, as shown in FIG. 4B, when the trajectory ZL intersects from the start point SP to the end point EP and has an intersection CP, the aiming cursor generation unit 22 generates the aiming cursor K1. .

  When a trajectory ZL as shown in FIG. 4B is acquired by the trajectory acquisition unit 21, the aiming cursor generation unit 22 is the same as the aiming cursor K1 corresponding to the shape of the trajectory ZL, that is, the trajectory KL. An aiming cursor K1 having the same shape and size is generated. However, this is only an example, and the aiming cursor generation unit 22 may generate the aiming cursor K1 by interpolating the trajectory ZL in the shape of a circle. In this case, the aiming cursor generation unit 22 may generate a circle having the same area as the area in the trajectory ZL as the aiming cursor K1.

  Further, even when the trajectory ZL is not a closed loop, the aiming cursor generation unit 22 has a case where the distance D1 between the start point SP and the end point EP of the trajectory ZL is smaller than the specified distance as shown in FIG. The aiming cursor K1 may be generated. Here, as the specified distance, a value determined in advance according to the level of the player set by the level setting unit 26 may be adopted. Specifically, a value that becomes shorter as the player's level becomes higher may be adopted as the specified distance.

  Thereby, it becomes possible to change the difficulty level of a game according to the skill level of the game of the player, and the fun of the game can be further enhanced.

  Further, as shown in FIG. 4B, the aiming cursor generation unit 22 performs a trajectory section ZL1 between the intersection CP and the start point SP and a trajectory section between the intersection CP and the end point EP when the trajectory ZL is in a closed loop. It is preferable to generate the aiming cursor K1 by removing ZL2. Thereby, the aesthetics of the aiming cursor K1 can be improved.

  Further, the aiming cursor generation unit 22 may generate the aiming cursor K1 so that the contour line becomes thicker when the time required for the player to draw the closed loop is longer than the specified time. FIG. 5 is a diagram showing the aiming cursor K1 having a thick outline.

  As shown in FIG. 5, it can be seen that the outline of the aiming cursor K1 is thicker than the outline of the aiming cursor K1 shown in FIG. Here, the aiming cursor generator 22 counts the time required for the finger to touch and move from the start point SP to the end point EP when drawing the trajectory ZL, and when the measured time is longer than the specified time, the aiming cursor K1 The aiming cursor K1 may be generated so that the contour line becomes thicker by a predetermined width toward the outside of the contour than the normal thickness.

  Returning to FIG. 2, the cursor moving unit 23 moves the aiming cursor K <b> 1 in the game space and moves and displays it on the display screen based on the operation instruction from the player input to the operation display unit 10.

  FIG. 6 is a diagram showing an arrangement position of the aiming cursor K1 in the game space. In the present embodiment, a virtual three-dimensional space defined by three axes orthogonal to each other of the x axis, the y axis, and the z axis is employed as the game space.

  6 is set in a direction parallel to the straight line L3 connecting the center O2 of the pitcher mound and the center O3 of the home base HB in the virtual three-dimensional space, the z axis is set in the vertical direction, Is set in a direction perpendicular to the vertical direction and the straight line L3.

  In the present embodiment, the aiming cursor K1 moves on the plane SF1 that passes through the center O3 of the home base HB and is parallel to the xz plane, for example.

  FIG. 7 is a schematic diagram showing the relationship between the attitude of the game apparatus and the moving speed of the aiming cursor K1. In the present embodiment, the inclination angle θp of the pitch axis of the game device is associated with the moving speed Vz of the aiming cursor K1 in the z direction of the virtual three-dimensional space, and the inclination angle θr of the roll axis is the x direction of the virtual three-dimensional space. Is associated with the moving speed Vx of the aiming cursor K1. In this embodiment, when the display screen of the game apparatus is parallel to the horizontal plane, θp = 0 and θr = 0.

  Specifically, the tilt angle θr is calculated with a positive value in the clockwise direction and a negative value in the counterclockwise direction when the roll axis is viewed from the front of the player to the back side.

  Therefore, when the tilt angle θr is positive, the moving speed Vx has a positive value, and the aiming cursor K1 moves to the right on the display screen. When the inclination angle θr is negative, the moving speed Vx has a negative value, and the aiming cursor K1 moves to the left on the display screen.

  Further, the inclination angle θp is calculated with a positive value in the counterclockwise direction and a negative value in the clockwise direction when the pitch axis is viewed from the left to the right.

  Therefore, when the inclination angle θp is positive, the moving speed Vz has a positive value, and the aiming cursor K1 moves to the back side. When the inclination angle θp is negative, the moving speed Vz has a negative value, and the aiming cursor K1 moves to the near side.

  The cursor moving unit 23 obtains a combined vector of the moving speed Vz and the moving speed Vx, sets the direction of the combined vector as the moving direction of the aiming cursor K1, and sets the magnitude of the combined vector as the moving speed Vk of the aiming cursor K1. As a result, the aiming cursor K1 is moved on the plane SF1 shown in FIG. Thereby, as shown in FIG. 7, the aiming cursor K1 is moved and displayed in the direction of the arrow indicating the direction of the moving speed Vk on the display screen.

  Note that the inclination angle θp and the movement speed Vz have a relationship in which the absolute value of the movement speed Vz increases as the absolute value of the inclination angle θp increases. In addition, the inclination angle θr and the movement speed Vx have a relationship in which the absolute value of the movement speed Vx increases as the absolute value of the inclination angle θr increases.

  Therefore, as the absolute values of the tilt angles θp and θr increase, that is, as the tilt angles with respect to the pitch axis and the roll axis of the game apparatus increase, the moving speed of the aiming cursor K1 increases.

  Here, the cursor moving unit 23 calculates the amount of change in the angle of the operation display unit 10 by integrating the angular velocity signal output from the operation display unit 10 at a constant time interval, and calculates the calculated amount of change in the angle. The inclination angles θp and θr may be calculated by integrating.

  The initial position of the aiming cursor K1 in FIG. 6 can be, for example, the point P1 at the center position of the strike zone on the straight line L4 parallel to z passing through the center O3. Therefore, the cursor moving unit 23 may arrange the aiming cursor K1 in the virtual three-dimensional space so that the center of gravity of the aiming cursor K1 is located at the point P1 when the aiming cursor K1 is generated.

  Further, as the fixed time interval for calculating the moving speed Vz of the aiming cursor K1 by the cursor moving unit 23, for example, a time of 3 frames, that is, a value of about 3/60 seconds (0.5 seconds) may be adopted. Although it is possible, it is not limited to this, and it may be shorter or longer than 0.5 seconds.

  Returning to FIG. 2, the cursor moving unit 23 may decrease the moving speed of the aiming cursor K1 as the area of the aiming cursor K1 increases. In this case, the cursor moving unit 23 obtains a correction coefficient α that reduces the magnitude of the moving speed Vk as the area of the aiming cursor K1 increases, and multiplies the moving speed Vk by the correction coefficient α (α · Vk). ), The magnitude of the moving speed Vk may be corrected. Here, the cursor moving unit 23 receives the area of the aiming cursor K1 as an input, outputs the correction coefficient α, and corrects using a predetermined function in which the correction coefficient α decreases as the area of the aiming cursor K1 increases. The coefficient α may be calculated.

  FIG. 8 is a diagram for explaining the relationship between the area of the aiming cursor K1 and the moving speed of the aiming cursor K1, (A) shows a case where the area of the aiming cursor K1 is small, and (B) shows the aiming cursor K1. The case where the area of is large is shown.

  The aiming cursor K1 shown in FIG. 8B has a larger area than the aiming cursor K1 shown in FIG. Therefore, the correction coefficient α in FIG. 8B has a smaller value than the correction coefficient α in FIG. Therefore, the aiming cursor K1 shown in FIG. 8B moves more slowly than the aiming cursor K1 shown in FIG.

  Returning to FIG. 2, the timing acquisition unit 24 acquires a timing signal output from the operation display unit 10 when a batting instruction for determining the batting timing of the ball object BL1 is input by the player. The timing signal is output, for example, when the player touches a hit button displayed at a predetermined position on the display screen of the operation display unit 10. Here, the timing acquisition unit 24 may acquire a timing signal after the aiming cursor K1 is generated and there is a remaining time in the event period.

  When the timing acquisition unit 24 acquires the timing signal, the action imparting unit 25 performs a hit determination process that determines that the ball object BL1 has been hit if at least a part of the ball object BL1 and the aiming cursor K1 overlap. To do.

  FIG. 9 is an explanatory diagram of a hit determination process executed by the action applying unit 25. FIG. 9 shows a state where the virtual three-dimensional space shown in FIG. 6 is viewed in the x-axis direction.

  Specifically, when the timing acquisition unit 24 acquires the timing signal, the action applying unit 25, as shown in FIG. 9, when the ball object BL1 intersects or touches the aiming cursor K1 on the plane SF1, It is determined that the ball object BL1 has been hit.

  However, in this case, the difficulty level of the game is increased, and there is a possibility that the game is not interesting. Therefore, in the present embodiment, for example, when the timing acquisition unit 24 acquires a timing signal, the y component of the ball object BL1 is positioned at a distance d1 in the −y direction with respect to the plane SF1 and the plane SF1. If the extension line of the ball object BL1 at that time crosses the aiming cursor K1 on the plane SF1 and exists at a position separated by a distance d2 in the + y direction, it can be determined that the ball object BL1 has been hit. .

  Here, as an extension line of the ball object BL1, for example, a straight line extending from the mass point G1 positioned at the center of gravity of the ball object BL1 in the direction of the speed of the ball object when the timing acquisition unit 24 acquires the timing signal is used. can do.

  Alternatively, when the timing acquisition unit 24 acquires the timing signal, the y component of the ball object BL1 exists between a position that is a distance d1 away from the plane SF1 and a position that is a distance d2 away from the plane SF1. In this case, a plane SF1 ′ passing through the mass point G1 of the ball object BL1 and parallel to the plane SF1 is set, the aiming cursor K1 on the plane SF1 is projected on the set plane SF1 ′, and the projected aiming cursor K1 is within the region of the projected aiming cursor K1. If the ball object BL1 exists, it may be determined that the ball object BL1 has been hit.

  As d1 and d2, the same distance as the length of the y component of the strike zone from the plane SF1, or a distance obtained by adding or subtracting some margin may be employed.

  Returning to FIG. 2, as the length of the trajectory sections ZL <b> 1 and ZL <b> 2 shown in FIG. 4B increases, the action imparting unit 25 decreases the hitting power to the ball object BL <b> 1 (an example of power when applying the action). Set the hitting power to be.

  In this way, by setting the hitting power weak, a penalty can be imposed on the player. Here, the penalty means that a penalty is given to the player in the progress of the game. In this embodiment, the penalty given to the player is realized by reducing the hitting power.

  As the hitting power, for example, the magnitude and direction of the initial velocity V0 of the hit ball object BL1 are employed.

  In the present embodiment, the action imparting unit 25 changes the direction and magnitude of the reference initial speed Vref having a predetermined direction and magnitude according to the passing position of the ball object BL1 in the aiming cursor K1. The direction and magnitude of the initial speed V0 are calculated.

  Therefore, the action imparting unit 25 obtains the correction coefficient β1 that decreases the magnitude of the reference initial speed Vref as the length of the trajectory sections ZL1 and ZL2 (specifically, ZL1 + ZL2) increases, and determines the correction coefficient β1 as the reference initial value. By multiplying the speed Vref (β1 · Vref), the reference initial speed Vref is corrected, and the corrected reference initial speed Vref may be set as the initial speed V0.

  Note that the action applying unit 25 receives the correction coefficient β1 as an output, receives the trajectory section ZL1 + the trajectory section ZL2, and uses a predetermined function in which the correction coefficient β1 decreases as the trajectory section ZL1 + the trajectory section ZL2 increases. The correction coefficient β1 may be calculated.

  In addition, the action imparting unit 25 may set the magnitude of the initial speed V0 to be smaller as the shape of the trajectory ZL acquired by the trajectory acquisition unit 21 departs from a predetermined reference shape.

  FIG. 10 is an explanatory diagram of a determination process performed by the action imparting unit 25 as to whether or not the shape of the locus ZL is away from the reference shape. FIG. 10A illustrates an example of the reference shape ZR, and FIG. 10B illustrates the reference shape ZR. It is the figure which showed the shift | offset | difference with locus | trajectory ZL.

  In the present embodiment, for example, a circle having a predetermined area is adopted as the reference shape ZR. The action imparting unit 25 obtains a difference between a predetermined area of the reference shape ZR and an area of the locus ZL, specifically, an absolute value of the difference (= | ZR area−ZL area |). Then, as the | ZR area−ZL area | increases, the action imparting unit 25 obtains a correction coefficient β2 for reducing the magnitude of the reference initial speed Vref, and multiplies the reference initial speed Vref by the correction coefficient β2. Thus, the magnitude of the reference initial speed Vref is corrected (β2 · Vref), and the magnitude of the corrected reference initial speed Vref may be set as the magnitude of the initial speed V0.

  Note that the action imparting unit 25 may obtain the deviation of the shape of the trajectory ZL from the reference shape ZR using another method instead of the difference in area. FIG. 11 is an explanatory diagram of another example of the determination process by the action imparting unit 25 as to whether or not the shape of the locus ZL is away from the reference shape.

  In the method of FIG. 11, the action imparting unit 25 divides the locus ZL into a predetermined number of minute sections dl at equal intervals, and the difference between the angle θl formed by adjacent minute sections dl and the reference angle θref. The sum of absolute values (= | θl−θref |) is obtained. Then, as the total increases, the action imparting unit 25 obtains a correction coefficient β2 for decreasing the initial speed V0, and multiplies the reference initial speed Vref by the correction coefficient β2 to obtain the magnitude of the reference initial speed Vref. The magnitude of the corrected reference initial speed Vref may be set as the magnitude of the initial speed V0. As the reference angle θref, an angle formed by tangents of minute sections when a circle is divided into a predetermined number of minute sections can be used.

  Returning to FIG. 2, when the trajectory ZL acquired by the trajectory acquisition unit 21 is in a closed loop, the action imparting unit 25 may set the hitting power to be larger as the area in the closed loop becomes smaller.

  In this case, the action imparting unit 25 obtains the area of the closed loop of the trajectory ZL, obtains a correction coefficient β3 for increasing the magnitude of the reference initial speed Vref as the area of the closed loop decreases, and uses the correction coefficient β3 as a reference. By multiplying the initial speed Vref (β3 · Vref), the magnitude of the reference initial speed Vref is corrected, and the magnitude of the corrected reference initial speed Vref may be set as the magnitude of the initial speed V0.

  The action applying unit 25 outputs the correction coefficient β3, receives the closed loop area as an input, and calculates the correction coefficient β3 using a predetermined function in which the correction coefficient β3 increases as the closed loop area decreases. Good.

  Further, the action applying unit 25 sets the hitting power to be larger as the passing position of the center of gravity of the ball object BL1 with respect to the aiming cursor K1 when the timing obtaining unit 24 acquires the timing signal is closer to the center of gravity of the aiming cursor K1. Also good.

  FIG. 12 is a diagram showing a calculation process of the direction of the initial velocity of the hit ball object BL1, (A) shows the aiming cursor K1, and (B) shows the ball object BL1 immediately after hit in the x direction. (C) shows a state in which the ball object BL1 immediately after hitting is seen from the z direction.

  As shown in FIG. 12A, it is assumed that the center of gravity of the ball object BL1 has passed a point P4 (u, v) in the hitting area. However, u is a coordinate axis passing through the center O1 of the aiming cursor K1 and parallel to the x axis, and v is a coordinate axis passing through the center O1 and parallel to the z axis.

  In this case, the action imparting unit 25 obtains the distance ds between the point P4 and the center O1, obtains a correction coefficient β4 for setting the reference initial speed Vref to be smaller as the distance ds increases, and uses the correction coefficient β4 as a reference. By multiplying the initial speed Vref (β4 · Vref), the magnitude of the reference initial speed Vref is corrected, and the magnitude of the corrected reference initial speed Vref may be set as the magnitude of the initial speed V0.

  Note that the action applying unit 25 may calculate the correction coefficient β4 using a predetermined function in which the correction coefficient β4 is output, the distance ds is input, and the correction coefficient β4 increases as the distance ds decreases.

  Further, as shown in FIG. 4A, the action imparting unit 25 determines the distance D1 when the aiming cursor K1 is generated even when the trajectory where the player moves the finger in contact is not in a closed loop. As the power increases, the hitting power may be set smaller.

  In this case, the action imparting unit 25 obtains a correction coefficient β5 for reducing the magnitude of the reference initial speed Vref as the distance D1 increases, and multiplies the reference initial speed Vref by the correction coefficient β5 (β5 · Vref), the reference initial speed Vref may be corrected, and the corrected reference initial speed Vref may be set as the initial speed V0.

  Note that the action applying unit 25 may calculate the correction coefficient β5 using a predetermined function in which the correction coefficient β5 is output, the distance D1 is input, and the correction coefficient β5 increases as the distance D1 increases.

  Next, a method for calculating the direction of the initial velocity V0 of the ball object BL1 will be described with reference to FIGS. As shown in FIG. 12 (A), if v at point P4 is negative, it is determined that the hitting point by the bat object BT is located below the sweet spot of the bat object BT, as shown in FIG. 12 (B). Further, the pitch angle θ1 of the reference initial speed Vref is increased according to the value of v, and the pitch angle θ1 of the increased reference initial speed Vref is set as the pitch angle of the initial speed V0.

  On the other hand, if v of the point P4 is positive, it is determined that the hitting point by the bat object BT is located above the sweet spot, and the pitch angle θ1 of the reference initial speed Vref is decreased according to the value of v, and after the decrease The pitch angle θ1 of the reference initial speed Vref is set as the pitch angle of the initial speed V0.

  If u at point P4 is positive, in the case of a right batter, it is determined that the hit point by the bat object BT is located on the tip side opposite to the grip end from the sweet spot, as shown in FIG. Then, the yaw angle θ2 of the reference initial speed Vref is changed to the + θ2 side according to the value of u, and the yaw angle θ2 of the reference initial speed Vref after the change is set as the yaw angle of the initial speed V0.

  On the other hand, if u at point P4 is negative, in the case of a right batter, the hit point by the bat object BT is located closer to the grip end than the sweet spot, so the yaw angle θ2 of the reference initial speed Vref is set according to the value of u. The yaw angle θ2 of the reference initial speed Vref after the change is set as the yaw angle of the initial speed V0.

  Furthermore, as shown in FIG. 9, when the timing signal is acquired by the timing acquisition unit 24 when the ball object BL1 is positioned on the −y side from the plane SF1, that is, the hit timing of the ball object BL1 is fast. In the case, as shown in FIG. 12C, in the case of a right batter, the yaw angle θ2 of the reference initial speed Vref is increased to the −θ2 side according to the value of d, and the yaw angle of the reference initial speed Vref after the increase is increased. θ2 is set as the yaw angle of the initial speed V0.

  On the other hand, when the timing signal is acquired by the timing acquisition unit 24 when the ball object BL1 is positioned on the + y side from the plane SF1, that is, when the hit timing of the ball object BL1 is late, FIG. As shown, in the case of a right batter, the yaw angle θ2 of the reference initial speed Vref is increased to the + θ2 side according to the value of d, and the yaw angle θ2 of the increased reference initial speed Vref is set as the yaw angle of the initial speed V0. To do.

  Returning to FIG. 2, the level setting unit 26 sets the level of the player based on the operation instruction of the player. Here, prior to the start of the game, the level setting unit 26 displays an operation image for causing the player to set the level on the operation display unit 10, and the operation display unit 10 accepts the operation image by operating the operation image. The player level may be set based on the given player operation command.

  The storage unit 30 includes a game control program storage unit 31, an image data storage unit 32, and a character data storage unit. The game control program storage unit 31 stores a game control program for causing the game device shown in FIG. 1 to execute the above-described baseball game.

  The image data storage unit 32 stores various image data necessary for playing a baseball game such as a batter character CL1, a bat object BT, a background image of a baseball field, a pitcher character CL2, and a fielder character. Here, as the image data of the background image of the baseball field, for example, image data created in advance by rendering a virtual three-dimensional model created in advance in a virtual three-dimensional space from a predetermined viewpoint can be adopted. .

  The character data storage unit 33 stores information related to the batting ability of the batter character CL1 (particularly, the range in which the ball can be returned). As described above, before the player touches the operation display unit 10 with his / her finger, the maximum area MD in which a closed loop serving as the aiming cursor K1 can be drawn is semi-transparent and circular in advance. However, the size of the maximum area MD is individually set according to the batting ability of the batter character CL1. In this setting, information in the character data storage unit 33 is used.

  Next, the operation of the game device according to the present embodiment will be described. FIG. 13 is a flowchart showing the operation of the game device according to the embodiment of the present invention.

  First, in step S <b> 1, the program execution unit 20 stores image data such as a batter character CL <b> 1, a bat object BT, a baseball field background image, a pitcher character CL <b> 2, and a fielder character from the image data storage unit 32. Read and display, and make initial settings. In this case, for example, an image as shown in FIG.

  Next, the program execution unit 20 causes the pitcher character CL2 to perform an action, and starts an event period (step S2). Here, the program execution unit 20 may start the event period when a predetermined time has elapsed after the completion of the initial setting, or may start the event period in accordance with an operation instruction from the player.

  Further, when the event period is started by the program execution unit 20, the trajectory acquisition unit 21 starts a process of acquiring the trajectory ZL when the player touches and moves the finger on the display screen.

  In addition, the program execution unit 20 starts the movement of the ball object BL1 when a predetermined time has elapsed since the start of the event period. At this time, the program execution unit 20 changes the display mode of the pitcher character CL2 so that the pitcher character CL2 throws the ball object BL1.

  Further, the program execution unit 20 sets the initial velocity of the ball object BL1, regards the center of gravity of the ball object BL1 as a mass point, and sets the initial velocity and the gravitational acceleration previously given in the vertical direction downward in the virtual three-dimensional space. The position of the ball object BL1 in the virtual three-dimensional space is repeatedly calculated by solving the mass equation of motion using various external forces such as lift and the mass of the ball object BL1, and the trajectory of the ball object BL1 And the ball object is moved and displayed on the operation display unit 10 along the calculated trajectory.

  In this case, the program execution unit 20 randomly determines the ball type and the course according to the probabilities determined in advance for each ball type and the course, and draws the trajectory corresponding to the determined ball type and the course so that the ball object BL1 A predetermined external force is applied to the ball object BL1 so as to move. In addition, what is necessary is just to employ | adopt as what is predetermined according to the situation of a game, and pitcher character CL2 as a probability predetermined for every ball type and course.

  Moreover, what is necessary is just to employ | adopt the value predetermined according to the aspect of the game and pitcher character CL2 as a magnitude | size of initial velocity. Thereby, as shown in FIG. 3, the ball object BL1 is moved and displayed from the pitcher character CL2 toward the home base so as to draw a trajectory according to the ball type or course designated by the player.

  Next, the trajectory acquisition unit 21 acquires the trajectory of the finger that the player has moved in contact on the display screen (step S3). Here, the trajectory acquisition unit 21 determines that the touch movement has ended when the player releases the finger from the display screen after starting the touch movement of the finger, and acquires a trajectory in step S3. ). On the other hand, the trajectory acquisition unit 21 determines NO in step S3 when the finger has not been released from the display screen after the player has started touching and moving the finger, and the process proceeds to step S9. The process of acquiring the trajectory ZL is continued until the end.

  When the trajectory acquisition unit 21 acquires the trajectory ZL (YES in step S3), the aiming cursor generation unit 22 determines whether or not the trajectory ZL forms a closed loop (step S4), and forms a closed loop. If it is determined that YES (YES in step S4), the process proceeds to step S5. On the other hand, if it is determined that the locus ZL does not form a closed loop (NO in step S4), the process proceeds to step S9, and the player again moves the locus by touching the finger until the event period ends. Can be entered. The details of the process for determining whether or not a closed loop has been formed have been described above.

  Next, the aiming cursor generating unit 22 generates the aiming cursor K1 (step S5), and the cursor moving unit 23 receives an instruction to move the aiming cursor K1 from the player by tilting the main body of the game apparatus. Is received (YES in step S6), the aiming cursor K1 is moved and displayed on the display screen at a moving speed corresponding to the tilt angle (step S7).

  On the other hand, when the operation display unit 10 receives an instruction to stop the movement of the aiming cursor K1 by making the main surface of the game device parallel to the horizontal plane (NO in step S6), the cursor moving unit 23 After stopping the movement of K1, the aiming cursor K1 is displayed at that position, and the process proceeds to step S8.

  Next, when the hit button is touched by the player and the timing signal output from the operation display unit 10 is received (YES in step S8), the timing acquisition unit 24 advances the process to step S10.

  On the other hand, when the player does not touch the hit button and does not receive the timing signal output from the operation display unit 10 (NO in step S8), the timing acquisition unit 24 advances the process to step S9.

  In step S9, the timing acquisition unit 24 determines whether or not the event period has ended. If the event period has ended (YES in step S9), the process proceeds to step S12, and the event period has not ended. (NO in step S9), the process returns to step S3.

  That is, the processes from step S3 to S9 are repeated until the event period ends, an operation instruction for generating the aiming cursor K1 by the player, a movement instruction for moving the aiming cursor K1 by the player, and a batting instruction by the player Is accepted.

  If the timing acquisition unit 24 can acquire the timing signal by the end of the event period (YES in step S8), the action imparting unit 25 determines that the player has given a batting instruction, and performs the process. Proceed to S10.

  On the other hand, when the timing acquisition unit 24 cannot acquire the timing signal until the event period ends (NO in step S8 and YES in step S9), the action giving unit 25 is assumed to have been sent off by the player. Determination is made and the process proceeds to step S12.

  Also, if the player cannot draw a trajectory before the end of the event period (NO in step S3 and YES in step S9), or the player has drawn a trajectory but it is not a closed loop If the result is NO (YES in step S4 and YES in step S9), the action imparting unit 25 determines that the player has sent off and advances the process to step S12.

  In step S10, the action imparting unit 25 performs a hit determination process, and determines whether or not the player has hit the ball object BL1. Then, when it is determined that the player has hit the ball object BL1 (YES in step S10), the action imparting unit 25 performs a process of setting the hitting power (step S11), and the initial velocity V0 of the ball object BL1. Is calculated, and the hitting process is executed (step S13).

  In this case, the action imparting unit 25 causes the operation display unit 10 to display an image that clearly indicates that the ball object BL1 has been hit by the bat object BT, as shown in FIG.

  The action imparting unit 25 calculates the trajectory of the hit ball object BL1, and moves and displays the ball object BL1 along the calculated trajectory. In this case, the action imparting unit 25 regards the center of gravity of the ball object BL1 as a mass point, and solves the mass equation of motion using the initial velocity V0 of the ball object BL1 calculated in step S11, thereby determining the position of the ball object BL1. By repeatedly calculating, the trajectory of the ball object BL1 is calculated, and the ball object BL1 is moved and displayed on the operation display unit 10 along the calculated trajectory.

  On the other hand, when it is determined that the player has not been able to hit the ball object BL1 (NO in step S10), that is, when the player has swung the ball object BL1, the pitcher character CL2 moves the bat object. After the image to be swung is displayed on the operation display unit 10, an emptying process such as causing the operation display unit 10 to display an image in which the catcher character catches the ball object BL1 is executed (step S14).

  In step S <b> 12, the action imparting unit 25 performs a see-off process such as causing the operation display unit 10 to display an image in which the catcher character catches the ball object.

  As described above, according to the game device according to the present embodiment, when the player gives an operation instruction to move the finger in a predetermined closed loop on the display screen of the operation display unit 10, the operation instruction is displayed. Based on this, a trajectory in which the player actually moves his / her finger is acquired, and an aiming cursor K 1 having a shape corresponding to the trajectory is generated and displayed on the operation display unit 10.

  The player operates the operation display unit 10 to move the aiming cursor K1 in the game space. Then, when a player inputs a batting instruction for determining the timing of applying an action to the ball object BL1, a timing signal is output from the operation display unit 10 and acquired by the timing acquisition unit 24. If the ball object BL1 passes the aiming cursor K1 when the timing signal is acquired, it is determined that the ball object BL1 has hit.

  In other words, in order to display the aiming cursor K1 on the display screen, the player is required to perform a completely new operation that is not performed in the past, such as moving a finger on the display screen.

  Therefore, it is possible to make full use of the characteristics of the game device including the operation display unit 10 including the touch pad, and at the same time, it is possible to realize a game having unprecedented interest.

  In the above embodiment, the aiming cursor K1 is moved by tilting the operation display unit 10, but the present invention is not limited to this. For example, the aiming cursor K1 may be moved and displayed by sliding the operation display unit 10 in an arbitrary direction.

  In this case, an acceleration sensor is provided in the operation display unit 10, and the acceleration signal output from the acceleration sensor is integrated twice. For example, by using the method disclosed in Japanese Patent No. 3947549, the aiming cursor K1 is displayed on the display screen. It is only necessary to calculate the movement amount at, and move and display the aiming cursor K1 according to the calculated movement amount.

  Further, for example, an operation image of a cross key that can specify four directions of up, down, left, and right is displayed on the operation display unit 10, and the aiming cursor K1 may be moved by touching the player with the cross key. .

  Further, as another method, for example, the finger is brought into contact with the outer edge of the aiming cursor K1 or an area within a predetermined distance from the outer edge, and the aiming cursor K1 is moved by touching and moving the touched finger on the display screen. Also good. In this method, if the finger is brought into contact with the side opposite to the approaching direction of the moving object, the player can generally move the aiming cursor K1 to an arbitrary position while grasping the positional relationship between them. It becomes possible.

  In the above description, the case where the present game device executes a baseball game is illustrated, but the present invention is not limited to this, and a ball game that hits the ball with a racket such as tennis, table tennis, squash, etc. is executed. May be.

  Moreover, you may make this game device perform a clay shooting game. In this case, the aiming cursor K1 may be the aim of the rifle, and the flying object that is the shooting target may be the moving object.
