A second liquid crystal display unit 32 is provided on the surface 30 a of the second housing 30. A speaker 34 is built in the second housing 30.

  FIG. 2 is a rear view of the game apparatus 10 in a folded state (a state in which the surface 20a of the first housing 20 and the surface 30a of the second housing 30 are combined). As shown in FIG. 2, buttons 24 l and 24 r are provided on the left and right sides of the rear side surface of the first housing 20, respectively. In addition, a memory card slot 26 into which a game memory card 40 (see FIG. 3), which is an information storage medium, can be mounted is provided at the center of the back side surface of the first housing 20. Note that other members (not shown) such as a power switch are also attached to the game apparatus 10.

  As shown in FIG. 3, the game apparatus 10 includes a touch screen 22 (first liquid crystal display unit 22a and touch panel 22b), operation key unit 24, memory card slot 26, second liquid crystal display unit 32, speaker 34, bus 42, micro A processor 44, a main memory 46, an image processing unit 48, an input / output processing unit 50, an audio processing unit 52, and a communication interface 54 are included. These are housed in a casing together with a battery (not shown), and are driven by the battery.

  The microprocessor 44 controls each part of the game apparatus 10 based on an operating system stored in a ROM (not shown) and a program stored in the game memory card 40. The main memory 46 includes a RAM, for example. A program read from the game memory card 40 is written to the main memory 46 as necessary. The main memory 46 is also used as a working memory for the microprocessor 44. The bus 42 is used for exchanging addresses and data among the units of the game apparatus 10.

Or you may make it supply a game program and game data to the game device 10 from a remote place via communication networks, such as the internet. Or you may make it supply a game program and game data to the game device 10 using various data communications, such as infrared communication.

  In the game apparatus 10, an action game is executed in which a player character (game character operated by the player) annihilates an enemy character in the game space. This action game is realized by executing a program stored in the game memory card 40.

  FIG. 4 shows an example of an action game screen. The game screen 60 is displayed on the touch screen 22 or the second liquid crystal display unit 32. A player character 62 (operation target) is displayed on the game screen 60 shown in FIG. Although the enemy characters are also displayed on the actual game screen 60, they are omitted in FIG. The player character 62 moves according to the player's operation. For example, the player character 62 moves in the direction instructed using the cross button 24c. For example, the player character 62 jumps when an upward direction is instructed using the cross button 24c. Further, for example, when an attack button (for example, button 24a) is pressed, the player character 62 throws a weapon 64 (moving body). The enemy character can be defeated by hitting the enemy 64 with the weapon 64.

  For example, the weapon 64 thrown by the player character 62 moves on a trajectory 66 as shown in FIG. That is, first, the weapon 64 moves in the front direction of the player character 62. Then, the weapon 64 rises after moving a certain distance, and finally makes a U-turn and moves in a direction opposite to the original moving direction (the front direction of the player character 62). The trajectory of the weapon 64 may be a trajectory different from the trajectory 66 shown in FIG.

  The weapon 64 has a property similar to a magnet. That is, when the player presses a predetermined button (the button 24r in the present embodiment) and the distance between the player character 62 and the weapon 64 at that time is equal to or less than a predetermined reference distance, the player character 62 and the weapon 64 are associated with each other. Then, the player character 62 continues to follow the weapon 64 while the player continues to press the button 24r. That is, the player character 62 continues to move while being pulled by the weapon 64. 5 and 6 show an example of the game screen 60 in this case. As shown in FIGS. 5 and 6, the game screen 60 in this case includes a circular image 70 (region guidance image) for guiding a target area whose distance from the player character 62 is equal to or less than a reference distance, and a player character 62. An arrow image 72 (direction guidance image) for guiding the direction to the weapon 64 is displayed. The circle image 70 is displayed when the player presses the button 24r. The player can grasp whether or not the weapon 64 is located in the target area with reference to the circular image 70. In addition, the player can know how to move the player character 62 in order to position the weapon 64 not located in the target area in the target area, using the circle image 70.

  Further, when the player character 62 is associated with the weapon 64 (that is, when the player character 62 is driven by the weapon 64), the player operates the cross button 24c so that the player character 62 and the weapon 64 are operated. The distance between can be changed. For example, when a direction substantially equal to the moving direction of the weapon 64 (or the direction from the player character 62 to the weapon 64) is instructed, the player character 62 approaches the weapon 64, and the player character 62 and the weapon 64 are positioned between them. The distance becomes shorter. Conversely, when a direction substantially equal to the reverse direction of the movement direction of the weapon 64 (or the reverse direction from the player character 62 to the weapon 64) is designated, the player character 62 moves away from the weapon 64, and the player character 62 And the distance between the weapon 64 increases. It should be noted that the thickness of the line indicating the circumference of the aforementioned circular image 70 changes based on the distance between the player character 62 and the weapon 64. As the distance between the player character 62 and the weapon 64 becomes longer, the line becomes thicker.

  When the player releases the button 24r while the player character 62 is associated with the weapon 64, the association between the player character 62 and the weapon 64 is released. That is, the player character 62 moves away from the weapon 64, and the player character 62 does not follow the weapon 64. The moving direction of the player character 62 in this case is set to the direction from the player character 62 to the weapon 64 when the button 24r is released (that is, the direction indicated by the arrow image 72). Then, the player character 62 moves in the moving direction by a moving distance based on the distance between the player character 62 and the weapon 64 when the pressing of the button 24r is released. If the distance between the player character 62 and the weapon 64 is long, the moving distance also becomes long. It should be noted that the player can predict the moving direction of the player character 62 after the association between the player character 62 and the weapon 64 is released, using the arrow image 72 as a basis. As described above, since the thickness of the line indicating the circumference of the circular image 70 changes based on the distance between the player character 62 and the weapon 64, the moving distance of the player character 62 in the moving direction is determined by the player. Can be predicted based on the thickness of the line indicating the circumference of the circular image 70.

  Incidentally, in the game screen 60 shown in FIG. 4, a block 68 is a place where the player character 62 cannot climb even if a normal jump is performed. In this regard, the player can move the player character 62 onto the block 68 by performing an operation described below. First, the player presses the button 24r at a timing when the distance between the player character 62 and the weapon 64 is equal to or less than the reference distance. For example, the player presses the attack button while pressing the button 24r. Since the initial position of the weapon 64 is set in the vicinity of the player character 62, in this case, the player character 62 and the weapon 64 are associated with each other when the weapon 64 is generated, and the player character 62 follows the weapon 64. Thereafter, the player increases the distance between the player character 62 and the weapon 64 by using the cross button 24 c to indicate a direction substantially equal to the reverse direction of the moving direction of the weapon 64. Then, for example, as shown in FIG. 5, the player releases the press of the button 24r at the timing when the arrow image 72 indicates the direction in which the block 68 exists. In this case, the player character 62 moves a relatively long distance in the direction indicated by the arrow image 72 when the pressing of the button 24r is released. That is, the player character 62 moves vigorously toward the block 68 and reaches the block 68.

  Hereinafter, a configuration for allowing the player to perform the movement operation of the player character 62 as described above will be described.

  FIG. 7 is a functional block diagram showing functions related to the present invention among the functions realized by the game apparatus 10. As shown in FIG. 7, the game apparatus 10 includes a storage unit 76, a display control unit 78, a moving body control unit 80, a first operation target control unit 82, a switching unit 84, and a second operation target. And a control unit 86.

  The storage unit 76 is realized by the main memory 46, for example. The storage unit 76 stores the current positions of the player character 62, weapon 64, and enemy character. For example, the current positions of the representative points of the player character 62, weapon 64, and enemy character are stored. The display control unit 78 is realized mainly by the microprocessor 44 and the image processing unit 48. The display control unit 78 displays the game screen 60 on the touch screen 22 or the second liquid crystal display unit 32 based on the stored contents of the storage unit 76. The moving body control unit 80, the first operation target control unit 82, and the second operation target control unit 86 update the current position of the player character 62 and the weapon 64 stored in the storage unit 76, whereby the game screen 60. The player character 62 and the weapon 64 displayed on the screen are moved.

  The moving body control unit 80 is realized mainly by the microprocessor 44. The moving body control unit 80 moves the weapon 64 (moving body). For example, the moving body control unit 80 generates the weapon 64 at an initial position determined based on the position of the player character 62 when the player presses the attack button. Then, the moving body control unit 80 moves the weapon 64 from the initial position according to a predetermined trajectory pattern (see the trajectory 66 in FIG. 4).

  The first operation target control unit 82 is realized mainly by the microprocessor 44. The first operation target control unit 82 associates the player character 62 (operation target) with the weapon 64 and causes the player character 62 to follow the weapon 64. For example, when the distance between the player character 62 and the weapon 64 is equal to or less than the reference distance, the first operation target control unit 82 associates the player character 62 with the weapon 64 and makes the player character 62 the weapon 64. Follow. The first operation target control unit 82 in the present embodiment performs a predetermined operation (pressing the button 24r), and when the distance between the player character 62 and the weapon 64 is equal to or less than the reference distance, The player character 62 is associated with the weapon 64 and the player character 62 is driven by the weapon 64.

  FIG. 8 is a diagram for explaining an example of position control of the player character 62 when the player character 62 is associated with the weapon 64 (when the player character 62 is driven by the weapon 64). In FIG. 8, reference numeral 62 a indicates a representative point of the player character 62. The representative point 62a is, for example, the center point of the head of the player character 62 or the center point of the trunk. Reference numeral 64 a indicates a representative point of the weapon 64. The representative point 64a is, for example, the center point of the weapon 64. Further, reference numeral 64b indicates the moving direction of the weapon 64. As shown in FIG. 8, for example, the position of the player character 62 is such that the representative point 62a of the player character 62 is positioned on a straight line 90 extending from the representative point 64a of the weapon 64 in the direction opposite to the moving direction 64b of the weapon 64. Is controlled. In other words, the player character is such that the angle (θ) between the moving direction 64b of the weapon 64 and the direction 92 from the weapon 64 (representative point 64a) to the player character 62 (representative point 62a) is 180 degrees. The position of 62 is controlled. In this case, the direction 94 from the player character 62 (representative point 62a) to the weapon 64 (representative point 64a) coincides with the moving direction 64b of the weapon 64. The aforementioned arrow image 72 is an image indicating the direction 94 (that is, the moving direction 64b of the weapon 64).

  When the player character 62 is associated with the weapon 64, the first operation target control unit 82 changes the positional relationship between the player character 62 and the weapon 64 based on the player's operation. For example, the first operation target control unit 82 changes the distance between the player character 62 and the weapon 64 based on the operation of the player. For example, the first operation target control unit 82 compares the direction instructed by the player with the moving direction 64b of the weapon 64 (or the direction 94 from the player character 62 to the weapon 64). Based on the comparison result, the first operation target control unit 82 changes the distance (r) between the player character 62 (representative point 62a) and the weapon 64 (representative point 64a). For example, when the direction instructed by the player and the moving direction of the weapon 64 are substantially equal, the distance (r) between the player character 62 and the weapon 64 is decreased. Further, for example, when the direction instructed by the player and the reverse direction of the moving direction 64b of the weapon 64 are substantially equal, the distance (r) between the player character 62 and the weapon 64 is increased.

  The switching unit 84 is realized mainly by the microprocessor 44. The switching unit 84 releases the association between the player character 62 and the weapon 64. That is, the switching unit 84 switches from a state in which the player character 62 follows the weapon 64 to a state in which the player character 62 does not follow the weapon 64 when a predetermined switching condition is satisfied. For example, the switching unit 84 releases the association between the player character 62 and the weapon 64 when the player performs a predetermined operation (cancels pressing of the button 24r). Note that the switching unit 84 may cancel the association between the player character 62 and the weapon 64 when a predetermined timing has come. The predetermined timing is, for example, a timing at which the elapsed time from the association between the player character 62 and the weapon 64 becomes a predetermined time.

  The second operation target control unit 86 is realized mainly by the microprocessor 44. The second operation target control unit 86 refers to the movement of the player character 62 after the switching by the switching unit 84 is performed at a timing corresponding to the execution of the switching by the switching unit 84 (hereinafter referred to as “switching timing”). Is controlled based on the positional relationship (for example, distance) between the player character 62 and the weapon 64. The “switching timing” can be paraphrased as a timing based on the timing at which switching by the switching unit 84 is executed. For example, the “switching timing” is the timing itself at which switching by the switching unit 84 is executed. Alternatively, the “switching timing” may be, for example, a predetermined timing immediately after the switching by the switching unit 84 or a predetermined timing immediately before the switching by the switching unit 84 is executed.

  The second operation target control unit 86 (moving direction determining means) sets the moving direction of the player character 62 after the switching by the switching unit 84, the direction 94 from the player character 62 to the weapon 64 at the switching timing, or This is determined based on the moving direction 64b of the weapon 64 at the switching timing. Further, the second operation target control unit 86 (movement distance control means) sets the movement distance of the player character 62 in the determined movement direction to the distance (r) between the player character 62 and the weapon 64 at the switching timing. Control based on. That is, the second operation target control unit 86 moves the player character 62 in the determined moving direction by a moving distance based on the distance (r) between the player character 62 and the weapon 64 at the switching timing.

  For example, the second operation target control unit 86 stores data in which the distance (r) between the player character 62 and the weapon 64 is associated with the movement distance. This data may be arithmetic expression data or table data. In this case, the second operation target control unit 86 acquires a movement distance corresponding to the distance (r) between the player character 62 and the weapon 64 at the switching timing based on the above data. Then, the second operation target control unit 86 moves the player character 62 in the moving direction by the moving distance.

  For example, the second operation target control unit 86 stores data in which the distance (r) between the player character 62 and the weapon 64 is associated with the movement time. This data may also be arithmetic expression data or table data. In this case, the second operation target control unit 86 acquires the movement time corresponding to the distance (r) between the player character 62 and the weapon 64 at the switching timing based on the above data. Then, the second operation target control unit 86 moves the player character 62 in the movement direction at a predetermined speed during the movement time.

  For example, the second operation target control unit 86 stores data in which the distance (r) between the player character 62 and the weapon 64 is associated with the moving speed. This data may also be arithmetic expression data or table data. The second operation target control unit 86 in this case acquires a moving speed corresponding to the distance (r) between the player character 62 and the weapon 64 at the switching timing based on the above data. Then, the second operation target control unit 86 moves the player character 62 in the moving direction at the moving speed for a predetermined time.

  For example, the second operation target control unit 86 stores data in which the distance (r) between the player character 62 and the weapon 64 is associated with the initial speed. This data may also be mathematical data or table data. In this case, the second operation target control unit 86 acquires the initial speed corresponding to the distance (r) between the player character 62 and the weapon 64 at the switching timing based on the above data. Then, the second operation target control unit 86 moves the player character 62 in the moving direction at the initial speed.

  Next, processing executed by the game apparatus 10 to realize the functional blocks shown in FIG. 7 will be described. 9 to 11 are flowcharts mainly showing processes related to the present invention among the processes executed by the game apparatus 10. The microprocessor 44 executes the processes shown in FIGS. 9 to 11 according to the program stored in the game memory card 40.

  As shown in FIG. 9, first, the microprocessor 44 (first operation target control unit 82) determines whether or not a predetermined button (button 24r) has been pressed (S101). When it is determined that the predetermined button has been pressed, the microprocessor 44 (first operation target control unit 82) determines whether or not the weapon 64 is located in the target area whose distance from the player character 62 is equal to or less than the reference distance. Is determined (S102). For example, it is determined whether or not the representative point 64a of the weapon 64 is included in the target area whose distance from the representative point 62a of the player character 62 is equal to or less than the reference distance.

  When it is determined that the predetermined button has not been pressed (S101: N), or when it is determined that the weapon 64 is not located within the target area (S102: N), the microprocessor 44 determines the position of the player character 62. Is updated according to the player's operation (S103). For example, the position of the player character 62 is updated to a position moved by a predetermined distance from the current position in the direction instructed using the cross button 24c. Further, the microprocessor 44 (the moving body control unit 80) determines whether or not the attack button has been pressed (S104). If it is determined that the attack button has been pressed, the microprocessor 44 (the moving body control unit 80) generates the weapon 64 at the initial position (S105). The initial position of the newly generated weapon 64 is set to a position having a predetermined positional relationship with the position of the representative point 62a of the player character 62 when the attack button is pressed. For example, the initial position of the newly generated weapon 64 is set to a position that is a predetermined distance away from the position of the representative point 62a of the player character 62 when the attack button is pressed. After the processing of S104 and S105 is executed, the microprocessor 44 (moving body control unit 80) updates the position of the weapon 64 according to a predetermined trajectory pattern (see trajectory 66 in FIG. 4) (S106). When a plurality of weapons 64 are displayed on the game screen 60, the position of each weapon 64 is updated.

  Although omitted in FIG. 9, the positions of enemy characters and the like are also updated in parallel with the processing of S103 to S106. Also, processing for determining whether or not the weapon 64 has hit the enemy character and processing for deleting the enemy character from the game screen 60 based on the determination result are executed. Further, a process for determining whether or not the player character 62 has been attacked by an enemy character and a process for increasing or decreasing the value of a parameter (for example, a physical strength parameter or a damage parameter) of the player character 62 based on the determination result are also executed. Is done.

  After the process of S106 is executed, the microprocessor 44 determines whether or not the game end condition is satisfied (S107). The game end condition is a condition for game over or a condition for game clear. The case where the game over condition is satisfied is, for example, a case where a value of a parameter (for example, a physical strength parameter or a damage parameter) that increases or decreases when the player character 62 is attacked by an enemy character becomes a predetermined value. is there. Further, the case where the condition for clearing the game is satisfied is, for example, a case where the player character 62 reaches a predetermined goal position, or a case where the player character 62 extinguishes a specific enemy character (boss character).

  When it is determined that the game end condition is satisfied, the microprocessor 44 and the image processing unit 48 display a game end screen on the touch screen 22 or the second liquid crystal display unit 32 (S109). On the other hand, when it is determined that the game end condition is not satisfied, the microprocessor 44 and the image processing unit 48 (display control unit 78) update the game screen 60 (S108). For example, the game screen 60 is updated based on the positions of the player character 62, weapon 64, and enemy character stored in the main memory 46 (storage unit 76). As a result, the positions of the player character 62, weapon 64, and enemy character displayed on the game screen 60 are updated. After the process of S108 is executed, the process of S101 is executed again. Except when it is determined in S102 that the weapon 64 is located within the target area, or when it is determined that the game end condition is satisfied in S107, the processing of S101 to S108 is performed every predetermined time (for example, 1/60 seconds). Repeatedly.

  When it is determined that the weapon 64 is located within the target area (S102: Y), the microprocessor 44 executes the process shown in FIG.

  That is, the microprocessor 44 (first operation target control unit 82) associates the player character 62 with one of the weapons 64 located in the target area (S110). When a plurality of weapons 64 are located in the target area, the player character 62 is associated with the weapon 64 closest to the player character 62. In this process, information for specifying the weapon 64 associated with the player character 62 is stored in the main memory 46.

  Further, the microprocessor 44 (switching unit 84) determines whether or not the pressing of the predetermined button (button 24r) is released (S111). If it is determined that pressing of the predetermined button has not been released, the microprocessor 44 (moving body control unit 80) updates the position of the weapon 64 according to a predetermined trajectory pattern (see trajectory 66 in FIG. 4) (S112). Thereafter, the microprocessor 44 (first operation target control unit 82) executes processing (S113 to S117) for causing the player character 62 to follow the weapon 64 associated with the player character 62.

  First, the microprocessor 44 determines whether or not the direction instructed using the cross button 24c is substantially equal to the moving direction 64b of the weapon 64 associated with the player character 62 (or the direction 94 from the player character 62 to the weapon 64). Is determined (S113). For example, as the moving direction 64b of the weapon 64, the direction from the position immediately before the weapon 64 to the current position of the weapon 64 is acquired. Further, for example, when the angle between the direction instructed using the cross button 24c and the moving direction 64b of the weapon 64 is equal to or smaller than the reference angle, the direction instructed using the cross button 24c is the movement of the weapon 64. It is determined that it is substantially equal to the direction 64b. If it is determined that the direction instructed using the cross button 24c is substantially equal to the moving direction 64b of the weapon 64 associated with the player character 62, the microprocessor 44 decreases the predetermined value (Δr) from the value of the variable r. (S114). As will be described later, the variable r indicates the distance between the player character 62 and the weapon 64 associated with the player character 62. Note that the initial value of the variable r is set to a predetermined value, for example.

  On the other hand, if it is determined that the direction indicated using the cross button 24c is not substantially equal to the moving direction 64b of the weapon 64 associated with the player character 62, the microprocessor 44 is indicated using the cross button 24c. It is determined whether or not the direction is substantially equal to the reverse direction of the moving direction 64b of the weapon 64 associated with the player character 62 (or the reverse direction of the direction 94 from the player character 62 to the weapon 64) (S115). For example, when the angle between the direction indicated using the cross button 24c and the reverse direction of the moving direction 64b of the weapon 64 is equal to or smaller than the reference angle, the direction indicated using the cross button 24c is the weapon 64. Is determined to be substantially equal to the reverse direction of the moving direction 64b. When it is determined that the direction indicated using the cross button 24c is substantially equal to the reverse direction of the moving direction 64b of the weapon 64 associated with the player character 62, the microprocessor 44 sets the value of the variable r to a predetermined value (Δr ) Are added (S116).

  After the processes of S113 to S116 are executed, the microprocessor 44 updates the position of the player character 62 based on the position of the weapon 64 associated with the player character 62 (S117). For example, the position of the representative point 62a of the player character 62 is a position on a straight line 90 extending from the representative point 64a of the weapon 64 associated with the player character 62 in the direction opposite to the moving direction 64b of the weapon 64, The weapon 64 is updated to a position where the distance from the representative point 64a is r (see FIG. 8). By executing this process, the player character 62 follows the weapon 64.

  Although omitted in FIG. 10, the positions of enemy characters and the like are also updated in parallel with the processing of S112 to S117. Also, processing for determining whether or not the weapon 64 has hit the enemy character and processing for deleting the enemy character from the game screen 60 based on the determination result are executed. Further, a process for determining whether or not the player character 62 has been attacked by an enemy character and a process for increasing or decreasing the value of a parameter (for example, a physical strength parameter or a damage parameter) of the player character 62 based on the determination result are also executed. Is done.

  After the process of S117 is executed, the microprocessor 44 determines whether or not the game end condition is satisfied (S118). This process is the same as S107. When it is determined that the game end condition is satisfied, the microprocessor 44 and the image processing unit 48 display a game end screen on the touch screen 22 or the second liquid crystal display unit 32 (S109).

  On the other hand, when it is determined that the game end condition is not satisfied, the microprocessor 44 and the image processing unit 48 (display control unit 78) update the game screen 60 (S119). This process is the same as the process of S108. However, in this case, the microprocessor 44 (region guide means, direction guide means) displays the circle image 70 and the arrow image 72 on the game screen 60. The display positions of the circle image 70 and the arrow image 72 are determined based on the display position of the player character 62. In this case, the microprocessor 44 (region guide means) determines the display mode of the circular image 70 based on the value of the variable r. For example, data in which the value of the variable r is associated with the display mode information related to the display mode of the circle image 70 is read from the game memory card 40. This data may be arithmetic expression data or table data. Then, display mode information corresponding to the value of the variable r is acquired based on the data, and the display mode of the circular image 70 is controlled based on the display mode information. In the case of the present embodiment, the display mode information is information indicating the thickness of the line indicating the circumference of the circular image 70, and as a result, the thickness of the line indicating the circumference of the circular image 70 is the variable r. Varies based on value. For example, the color of the line indicating the circumference of the circular image 70 or the color in the circular image 70 may be changed based on the value of the variable r. After the process of S119 is executed, the process of S111 is executed again. Unless it is determined in S111 that the predetermined button (button 24r) has been released, or in S118, it is determined that the game end condition has been satisfied, the processing in S111 to S119 is performed for a predetermined time (for example, 1/60 seconds). ) Repeatedly.

  If it is determined that the predetermined button (button 24r) has been pressed (S111: Y), the microprocessor 44 executes the processing shown in FIG.

  That is, the microprocessor 44 (second operation target control unit 86) determines the target movement position of the player character 62 after the association between the player character 62 and the weapon 64 is released (S120).

  First, the microprocessor 44 determines the moving direction of the player character 62 after the association between the player character 62 and the weapon 64 is released. The moving direction is determined as a direction 94 from the current position of the representative point 62 a of the player character 62 to the current position of the representative point 64 a of the weapon 64 associated with the player character 62.

  Further, the microprocessor 44 determines the moving distance in the moving direction. The moving distance is determined based on the value of the variable r. In this case, data in which the value of the variable r is associated with the movement distance is read from the game memory card 40. Then, the movement distance corresponding to the current value of the variable r is acquired based on the data.

  Then, the player character 62 after the association between the player character 62 and the weapon 64 is released after the position moved by the determined movement distance from the current position of the representative point 62a of the player character 62 in the determined movement direction. The moving target position is determined.

  Thereafter, the microprocessor 44 (switching unit 84) cancels the association between the player character 62 and the weapon 64 set in S110 (S121). For example, information for specifying the weapon 64 associated with the player character 62 is deleted from the main memory 46.

  Thereafter, the microprocessor 44 (the moving body control unit 80) updates the position of the weapon 64 according to a predetermined trajectory pattern (see the trajectory 66 in FIG. 4) (S122). Further, the microprocessor 44 (second operation target control unit 86) updates the position of the player character 62 (representative point 62a) to a position moved by a predetermined distance in the direction from the current position to the movement target position (S123). ). By executing this process, the player character 62 moves toward the movement target position.

  Although omitted in FIG. 11, the positions of enemy characters and the like are also updated in parallel with the processing of S122 and S123. Also, processing for determining whether or not the weapon 64 has hit the enemy character and processing for deleting the enemy character from the game screen 60 based on the determination result are executed. Further, a process for determining whether or not the player character 62 has been attacked by an enemy character and a process for increasing or decreasing the value of a parameter (for example, a physical strength parameter or a damage parameter) of the player character 62 based on the determination result are also executed. Is done.

  After the process of S123 is executed, the microprocessor 44 determines whether or not the game end condition is satisfied (S124). This process is the same as S107. When it is determined that the game end condition is satisfied, the microprocessor 44 and the image processing unit 48 display a game end screen on the touch screen 22 or the second liquid crystal display unit 32 (S109).

  On the other hand, when it is determined that the game end condition is not satisfied, the microprocessor 44 and the image processing unit 48 (display control unit 78) update the game screen 60 (S125). This process is the same as the process of S108. Thereafter, the microprocessor 44 (second operation target control unit 86) determines whether or not the player character 62 has moved to the movement target position determined in S120 (S126). When the player character 62 moves to the movement target position, the process of S101 is executed. On the other hand, when the player character 62 has not moved to the movement target position, the process of S122 is re-executed. Except when it is determined that the game end condition is satisfied in S124, or when it is determined that the player character 62 has moved to the movement target position in S126, the processing of S122 to S126 is performed for a predetermined time (for example, 1/60 seconds). Repeated every time.

  In the game apparatus 10 described above, the movement of the player character 62 (for example, the movement distance) after the player character 62 transitions from the state in which the player character 62 follows the weapon 64 to the state in which the player character 62 does not follow the weapon 64 is the transition. Control is performed based on the distance (r) between the player character 62 and the weapon 64 at the timing to be performed. For this reason, according to the game apparatus 10, the player moves the player character 62 after moving to the state where the player character 62 does not follow the weapon 64 (for example, the moving distance), and the player moves the player character 62 following the weapon 64. During this time, control can be performed by adjusting the distance (r) between the player character 62 and the weapon 64. That is, the operability related to the movement of the player character 62 can be improved.

  Further, in the game apparatus 10, when the player releases the press of the button 24 r, a transition is made from a state where the player character 62 follows the weapon 64 to a state where the player character 62 does not follow the weapon 64. For this reason, the player can adjust the timing at which the player character 62 is shifted to the state in which the player 64 is not driven by adjusting the timing at which the button 24r is released. As a result, the player can control the movement (for example, movement direction and movement distance) of the player character 62 after the player character 62 has shifted to a state in which it does not follow the weapon 64 by adjusting the timing at which the button 24r is released. It becomes like this.

  In the game apparatus 10, the display mode of the circle image 70 changes based on the distance (r) between the player character 62 and the weapon 64. Therefore, the player can easily grasp the distance (r) between the player character 62 and the weapon 64 by referring to the display mode of the circular image 70. As a result, the player can easily predict the movement (for example, the movement distance) of the player character 62 after the player character 62 shifts to a state in which it does not follow the weapon 64. That is, according to the game apparatus 10, the problem on the user interface that it is difficult to predict the movement (for example, the movement direction) of the player character 62 after the player character 62 shifts to a state in which the player character 62 does not follow the weapon 64 is solved.

  Further, in the game apparatus 10, when the distance between the player character 62 and the weapon 64 is equal to or less than the reference distance, the state in which the player character 62 does not follow the weapon 64 shifts to a state in which the player character 62 follows the weapon 64. . Therefore, the player can move the player character 62 to the weapon 64 by bringing the player character 62 closer to the weapon 64. Furthermore, in the game apparatus 10, when the player presses the button 24 r and the distance between the player character 62 and the weapon 64 is equal to or less than the reference distance, the game character 10 shifts to a state in which the player character 62 follows the weapon 64. Therefore, the player can instruct whether or not to cause the player character 62 to follow the weapon 64.

  In the game apparatus 10, the player can arbitrarily generate a weapon 64 that can be associated with the player character 62 by pressing the attack button.

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

  For example, when the player character 62 is associated with the weapon 64, the first operation target control unit 82 determines the angle between the moving direction 64 b of the weapon 64 and the direction 92 from the weapon 64 to the player character 62. (Θ) may also be changed based on the operation of the player. Thus, the player may change the direction 94 from the player character 62 to the weapon 64 by operating the cross button 24c. That is, the moving direction of the player character 62 after the player character 62 has shifted to a state where the player character 62 does not follow the weapon 64 may be adjusted by the player operating the cross button 24c.

  Further, for example, in S119 of FIG. 10, the microprocessor 44 (direction guide means) may determine the display mode of the arrow image 72 based on the value of the variable r. For example, data obtained by associating the value of the variable r with the display mode information regarding the display mode of the arrow image 72 may be read from the game memory card 40. This data may be arithmetic expression data or table data. Then, display mode information corresponding to the value of the variable r may be acquired based on the data, and the display mode of the arrow image 72 may be controlled based on the display mode information. For example, the display mode information is information indicating the thickness of the arrow of the arrow image 72. In this case, the thickness of the arrow of the arrow image 72 changes based on the value of the variable r. For example, the size, length, and color of the arrow of the arrow image 72 may be changed based on the value of the variable r. In this way, the player can easily predict the movement (for example, the movement distance) of the player character 62 after the player character 62 has shifted to a state in which the player 64 does not follow the weapon 64 by referring to the display mode of the arrow image 72. . That is, the problem on the user interface that it is difficult to predict the movement (for example, the movement direction) of the player character 62 after the player character 62 has shifted to a state in which the player 64 does not follow the weapon 64 is solved.

  Further, for example, the movement control unit 80 may move the weapon 64 from the initial position in a direction determined based on the direction instructed by the player. In this way, the player may be able to instruct the moving direction of the weapon 64 using the cross button 24c. That is, the player may be able to instruct the moving direction of the weapon 64 to which the player character 62 can be associated.

  Further, for example, instead of the player character 62 throwing the weapon 64, the player character 62 may fire a bullet or a magic bullet, for example. Also in this case, the player character 62 may be associated with a bullet or a magic bullet in the same manner as the weapon 64. Further, the moving object associated with the player character 62 may not be used for attacking enemy characters. Further, the moving body associated with the player character 62 may not be generated in accordance with the player's operation. Further, the operation target of the player may not be a game character imitating a human like the player character 62. The present invention can also be applied to games other than action games. The present invention can be applied to a game in which an operation target of a player and a moving object are displayed on a game screen. For example, the present invention can be applied to a soccer game. Here, an example in which the present invention is applied to the man mark function in a soccer game will be described. For example, the player presses a predetermined button (for example, button 24r), and the operation target character that is the soccer player character to be operated and the opponent character (moving body) that is the soccer player character of the opponent team at that time, When the distance between is less than or equal to a predetermined reference distance, the operation target character and the opponent character are associated with each other. Then, the operation target character follows the opponent character, and the operation target character marks the opponent character. In a state where the operation target character follows the opponent character, the positional relationship (distance, etc.) between the operation target character and the opponent character changes according to the player's operation. Then, when a predetermined switching condition is satisfied, the operation target character is switched from a state where the operation target character follows the opponent character to a state where the operation target character does not follow the other character. That is, the man mark for the opponent character of the operation target character is released. In this case, the movement control of the operation target character after the man mark is released is performed based on the positional relationship (distance etc.) between the operation target character and the opponent character at the timing when the man mark is released.

  Further, for example, a game executed on the game apparatus 10 is not limited to a game in which a two-dimensional game space constituted by two coordinate elements is displayed on the game screen. The game executed on the game apparatus 10 may be a game that displays a three-dimensional game space composed of three coordinate elements on a game screen. That is, the game executed on the game apparatus 10 may be a game in which the positions of the player character 62, the weapon 64, the enemy character, and the like are managed by three coordinate elements.

  In the above description, the program is supplied to the game apparatus 10 via the game memory card 40 as an information storage medium. However, the program may be distributed to the game apparatus 10 via a communication network. FIG. 12 is a diagram showing an overall configuration of a program distribution system using a communication network. A program distribution method according to the present invention will be described with reference to FIG. As shown in FIG. 12, the program distribution system 100 includes a program distribution device 108, a communication network 106, and a game device 10. The program distribution device 108 includes a database 102 and a server 104. The communication network 106 includes, for example, the Internet and a cable television network. In this system, a database (information storage medium) 102 stores a program similar to the storage content of the game memory card 40. Then, when a consumer makes a program distribution request using the game apparatus 10, this is transmitted to the server 104 via the communication network 106. Then, the server 104 reads the program from the database 102 in response to the program distribution request and transmits it to the game apparatus 10. Here, the program is transmitted in response to the program distribution request, but the program may be transmitted unilaterally from the server 104. Thus, if the program is distributed via the communication network 106, the consumer can easily obtain the program.
