  The configuration and operation of the game device according to one embodiment of the present invention will be described below.

  FIG. 1 is an external view of a game device according to an embodiment of the present invention. In FIG. 1, the game apparatus 10 includes a first LCD (Liquid Crystal Display) 11 and a second LCD 12. The housing 13 includes an upper housing 13a and a lower housing 13b. The first LCD 11 is accommodated in the upper housing 13a, and the second LCD 12 is accommodated in the lower housing 13b. The resolutions of the first LCD 11 and the second LCD 12 are both 256 dots × 192 dots. In this embodiment, an LCD is used as the display device. However, any other display device such as a display device using EL (Electro Luminescence) can be used. An arbitrary resolution can be used.

  The upper housing 13a is formed with sound release holes 18a and 18b for releasing sound from a pair of speakers (30a and 30b in FIG. 2) to be described later.

  The lower housing 13b is provided with a cross switch 14a, start switch 14b, select switch 14c, A button 14d, B button 14e, X button 14f, Y button 14g, L button 14L and R button 14R as input devices. Yes. As a further input device, a touch panel 15 is mounted on the screen of the second LCD 12. The lower housing 13b is also provided with a power switch 19 and an insertion port for storing the memory card 17 and the stick 16.

  As the touch panel 15, an arbitrary system such as a resistive film system, an optical system (infrared system), and a capacitive coupling system can be used. The touch panel 15 has a function of outputting coordinate data corresponding to the contact position when the surface of the touch panel 15 is touched with the stick 16. In the following description, it is assumed that the player operates the touch panel 15 with the stick 16, but it is of course possible to operate the touch panel 15 with a pen (stylus pen) or a finger instead of the stick 16. In the present embodiment, the touch panel 15 having a resolution (detection accuracy) of 256 dots × 192 dots is used as in the resolution of the second LCD 12. However, the resolution of the touch panel 15 and the resolution of the second LCD 12 are not necessarily the same.

  The memory card 17 is a recording medium on which a game program is recorded, and is detachably attached to an insertion port provided in the lower housing 13b.

  Next, the internal configuration of the game apparatus 10 will be described with reference to FIG.

In FIG. 2, a CPU core 21 is mounted on the electronic circuit board 20 accommodated in the housing 13. A connector 23 is connected to the CPU core 21 via a bus 22, an input / output interface circuit (referred to as I / F circuit in the drawing) 25, a first GPU (Graphics Processing Unit) 26, a second GPU 27, a RAM 24, and An LCD controller 31 is connected. The memory card 17 is detachably connected to the connector 23. The memory card 17 includes a ROM 17a that stores a game program and a RAM 17b that stores backup data in a rewritable manner. The game program stored in the ROM 17a of the memory card 17 is loaded into the RAM 24, and the game program loaded into the RAM 24 is executed by the CPU core 21. In addition to the game program, the RAM 24 stores temporary data obtained by the CPU core 21 executing the game program and data for generating a game image. The I / F circuit 25 is connected to the touch panel 15, the right speaker 30a, the left speaker 30b, and the operation switch unit 14 including the cross switch 14a and the A button 14d shown in FIG. The right speaker 30a and the left speaker 30b are respectively arranged inside the sound release holes 18a and 18b.

  A first VRAM (Video RAM) 28 is connected to the first GPU 26, and a second VRAM 29 is connected to the second GPU 27. In response to an instruction from the CPU core 21, the first GPU 26 generates a first game image based on data for generating a game image stored in the RAM 24, and draws the first game image in the first VRAM 28. Similarly, the second GPU 27 generates a second game image in accordance with an instruction from the CPU core 21 and draws it in the second VRAM 29. The first VRAM 28 and the second VRAM 29 are connected to the LCD controller 31.

  The LCD controller 31 includes a register 32. The register 32 stores a value of 0 or 1 according to an instruction from the CPU core 21. When the value of the register 32 is 0, the LCD controller 31 outputs the first game image drawn in the first VRAM 28 to the first LCD 11 and the second game image drawn in the second VRAM 29 as the second game image. Output to the LCD 12. When the value of the register 32 is 1, the first game image drawn in the first VRAM 28 is output to the second LCD 12, and the second game image drawn in the second VRAM 29 is output to the first LCD 11. To do.

  Note that the configuration of the game apparatus 10 as described above is merely an example, and the present invention can be applied to any computer system having a pointing device such as a touch panel, a mouse, or a touch pad and at least one display device. it can. Further, the game program of the present invention may be supplied not only to the computer system through an external storage medium such as the memory card 17 but also to the computer system through a wired or wireless communication line. May be recorded in advance in the non-volatile storage device.

  Next, an outline of a game executed by the game apparatus 10 will be described with reference to FIGS.

  When the game is started, as shown in FIG. 3, the state of a certain area of the game world is displayed on the second LCD 12. There are a plurality of player characters and a plurality of enemy characters in the game world. In the example of FIG. 3, only three player characters PC1 to PC3 and one enemy character EC are displayed on the screen, but other player characters and enemy characters are present in other areas of the game world. Existing. The player character is a character that can be operated by the player, and the enemy character is a character that is automatically controlled by a computer. Note that the player character may simply stop on the spot when the player is not performing any input operation, or may be controlled by a computer as if acting on his / her own will. .

  As shown in FIG. 4, the player can scroll the game image in a desired direction by touching the first peripheral area along the outer edge of the display screen of the second LCD 12 with the stick 16. By performing such a scrolling operation, the player can check the state of other areas of the game world that are not displayed on the display screen.

  The scroll direction of the game image is determined based on the contact position TP of the stick 16 with respect to the touch panel 15. For example, if the stick 16 is brought into contact with the right end of the display screen as shown in FIG. 4, the game image (game world) scrolls toward the left of the screen as shown in FIG. Thus, the player can check the state of the area located further to the right of the screen than the area of the game world currently displayed on the display screen. Further, for example, when the stick 16 is brought into contact with the lower right corner of the display screen as shown in FIG. 6, the game image scrolls in the upper left direction of the screen as shown in FIG. Thereby, the player can confirm the state of the area located in the lower right direction of the screen further than the area of the game world currently displayed on the display screen.

  There are several methods for determining the scroll direction of the game screen. As an example, a direction from the contact position TP of the stick 16 to the touch panel 15 toward the center of the display screen is set as a scroll direction.

  As shown in FIG. 8, the player can give a movement instruction to the player character by sliding the stick 16 on the touch panel 15 starting from the display position of an arbitrary player character. FIG. 8 shows an example of an input operation when the player character PC2 is moved rightward on the screen.

  The movement instruction is continuously given to the player character until the player releases the stick 16 from the touch panel 15. The player character that has received the movement instruction moves at a predetermined speed toward the contact position TP of the stick 16 (more precisely, toward the point in the game world corresponding to the contact position TP) as shown in FIG. . By performing such an input operation (hereinafter referred to as a movement operation), the player can guide a desired player character in a desired direction.

  Note that the player can also guide the player character to an area of the game world that is not currently displayed on the display screen by the above moving operation. Specifically, as shown in FIG. 10, during the movement operation, the stick 16 is slid to the second peripheral area along the outer edge of the display screen of the second LCD 12, and the movement operation is continued while the desired operation is performed. The game image can be scrolled in the direction. As apparent from a comparison between FIG. 4 and FIG. 10, the second peripheral region is a region different from the first peripheral region and is wider than the first peripheral region.

  Also in the scroll process during the moving operation as described above, the scroll direction of the game image is determined based on the contact position TP of the stick 16 with respect to the touch panel 15. For example, when the stick 16 is brought into contact with the right end of the display screen as shown in FIG. 10, the game image (game world) scrolls in the left direction of the screen as shown in FIG. Thereby, the player can guide the player character PC2 to the right side of the screen while confirming the state of the region located further to the right side of the screen than the region of the game world currently displayed on the display screen.

There are several methods for determining the scroll direction of the game screen during the moving operation. As an example, the direction from the contact position TP of the stick 16 to the touch panel 15 toward the center of the display screen may be the scroll direction, or the display of the player character that is the target of the moving operation from the contact position TP of the stick 16 to the touch panel 15. The direction toward the position may be the scroll direction.

  In the present embodiment, since the second peripheral area is set wider than the first peripheral area, it is easy to confirm the state of the player character in the moving direction during the moving operation, and the player character moves in the moving direction during the moving operation. It is possible to avoid encountering an enemy character that appears unexpectedly at a close distance. However, in the present invention, the second peripheral area is not necessarily set wider than the first peripheral area, and the second peripheral area may be narrower than the first peripheral area depending on the content of the game.

  Of course, the scroll operation and the movement operation as described above are also possible when coordinate input means other than the touch panel is used. For example, when a mouse is used as the coordinate input means, a scroll operation can be performed by pressing a button on the mouse after the pointer displayed on the screen is moved onto the first peripheral area. In this case, the scroll instruction is continuously input until the button on the mouse is released. Further, the moving operation can be performed by moving the pointer while pressing the button on the mouse after moving the pointer displayed on the screen onto the desired player character. In this case, the movement instruction is continuously input until the button on the mouse is released.

  Hereinafter, the operation of the game apparatus 10 will be described in more detail.

  FIG. 12 shows a memory map of the RAM 24. The RAM 24 stores a game program 40, character information 42, background information 44, first peripheral area information 46, second peripheral area information 48, a current input coordinate 50, a previous input coordinate 52, and an operating flag 54.

  The game program 40 is a program for causing the CPU core 21 to execute a game process, and is read from the ROM 17a into the RAM 24 prior to the execution of the game process.

  The character information 42 is information regarding player characters and enemy characters in the game world. As shown in FIG. 13, the character information 42 includes image data and state data of the player character and the enemy character. The state data includes current coordinates and an operation target flag for each character. The operation target flag is a flag indicating whether or not each character is a target of a moving operation by the player. The image data is read from the ROM 17a into the RAM 24 and used for generating a game image. The status data is updated as needed as the game progresses.

  The background information 44 is information regarding the ground, trees, etc. that make up the background of the game world. The background information also includes position information and image data.

  The first peripheral area information 46 and the second peripheral area information 48 are information indicating the ranges of the first peripheral area and the second peripheral area, respectively.

  The current input coordinate 50 is a coordinate indicating the contact position TP of the stick 16 with respect to the touch panel 15 and is updated at any time based on an output signal of the touch panel 15 at a constant cycle.

  The immediately preceding input coordinates 52 are the coordinates of the contact position TP detected immediately before the current input coordinates 50.

  The in-operation flag 54 is a flag indicating whether or not the movement operation by the player as shown in FIG. 9 is being performed.

  Next, the flow of processing of the CPU core 21 based on the game program 40 will be described with reference to the flowchart of FIG.

  When the game program 40 is executed, first, in step S10, the CPU core 21 performs an initialization process. This initialization process includes a process of arranging a player character and an enemy character in the game world.

  Thereafter, the processing of step S12 to step S30 is repeatedly executed at a constant cycle in synchronization with the screen update cycle (usually 1/60 second) of the second LCD 12.

  In step S <b> 12, the current input coordinates are detected based on the output signal from the touch panel 15 and stored in the RAM 24 as the current input coordinates 50. At this time, the value of the current input coordinate 50 before the update is held in the RAM 24 as the previous input coordinate 52.

  In step S14, based on the current input coordinates 50 and the current coordinates of each player character, it is determined whether or not the player has touched any player character with the stick 16. More specifically, it is determined whether or not the previous input coordinate 52 is “no input” and the current input coordinate 50 indicates the display position of any player character. As a result, if it is determined that the player has touched any player character with the stick 16, the in-operation flag 54 is turned on in step S16, and the operation target flag of the player character touched with the stick 16 is turned on. To.

  In step S18, it is determined whether or not the stick 17 has been removed from the touch panel 15. If it is determined that the stick 17 has been removed from the touch panel 15, the operating flag 54 is turned off in step S20, and the operation target flags of all player characters are turned off.

  In step S22, character movement processing is performed. Specifically, the current coordinates of the player character that is the moving operation target (that is, the player character for which the operation target flag is turned on) are directed to the point in the game world corresponding to the current input coordinate 50. Update to move at a predetermined speed. When there is no player character whose operation target flag is turned on, the process of step S22 is skipped.

  In step S24, various processes necessary for the progress of the game, such as enemy character movement processing, animation processing of each character, and generation of game sound, are performed.

  In step S26, scroll processing is performed. Details of this scroll processing will be described later.

  In step S28, a game image reflecting the scroll process of step S26 is generated, and this game image is displayed on the second LCD 12.

  In step S30, it is determined whether or not the game is finished. If the game is finished, the execution of the game program 40 is finished. If the game is not finished, the process returns to step S12 to process the next frame. Do.

  Next, details of the scroll process will be described with reference to the flowchart of FIG.

  In step S40, it is determined whether the in-operation flag 54 is on. If it is on, the process proceeds to step S48, and if it is off, the process proceeds to step S42.

  In step S42, the first peripheral area information 46 and the current input coordinates 50 are referred to, and it is determined whether or not the current input coordinates 50 indicate the inside of the first peripheral area. If the current input coordinate 50 points to the inside of the first peripheral area, the process proceeds to step S44. If not, the process proceeds to step S28 in FIG.

  In step S44, the current coordinates of each player character and the current input coordinates 50 are referred to and it is determined whether or not the current input coordinates 50 indicate any player character. If the input coordinates 50 currently point to any player character, the process proceeds to step S28 in FIG. 14, and if not, the process proceeds to step S46.

  In step S46, a scroll direction is determined based on the current input coordinates 50, and the game image is scrolled by a predetermined distance D1 in the scroll direction. Thereby, the game image is scrolled by the distance D1 per frame. That is, D1 can be said to be a value that defines the scroll speed.

  In the above step S44, the reason why the scroll process of step S46 is skipped when the current input coordinate 50 also points to any player character is in the first peripheral area as shown in FIG. 16, for example. This is to prevent the scroll process from being unexpectedly performed against the player's intention when the player tries to move the player character PC3 with the stick 16 (this leads to an erroneous operation). is there. If the player can input any instruction by touching the enemy character or tree with the stick 16, in step S44, the current input coordinate 50 is not limited to the player character and points to the enemy character or tree. Even if there is, the process may proceed to step S28 in FIG. Accordingly, it is possible to prevent an erroneous operation from occurring due to interference between the scroll operation and other input operations. However, in a game where such an erroneous operation is not particularly problematic, the process of step S44 may be omitted.

  In step S48, the second peripheral area information 48 and the current input coordinates 50 are referred to, and it is determined whether or not the current input coordinates 50 indicate the inside of the second peripheral area. If the current input coordinate 50 points to the inside of the second peripheral area, the process proceeds to step S50. If not, the process proceeds to step S28 in FIG.

  In step S50, a scroll direction is determined based on the current input coordinates 50, and the game image is scrolled in the scroll direction by a predetermined distance D2. Thereby, the game image is scrolled by the distance D2 per frame. That is, D2 can be said to be a value that defines the scroll speed.

  In the present embodiment, the value of D2 is set to a smaller value than D1. Thus, the response to the player's scroll instruction can be improved during the scroll operation, and the player character can be displayed on the display screen during the move operation by scrolling at the optimum speed according to the move speed of the player character during the move operation. It can be prevented from disappearing outside.

  In this embodiment, the peripheral area is set so as to surround the outer edge of the display screen. However, the present invention is not limited to this. For example, in a game in which the screen needs to be scrolled only in the horizontal direction, the peripheral area is set. May be arranged only on the left and right edges of the display screen. Similarly, in a game where it is necessary to scroll the screen only in the vertical direction, the peripheral area may be arranged only at the upper and lower edges of the display screen.

  In this embodiment, the scroll amount per frame is set to D1 or D2. However, the present invention is not limited to this. For example, the current input coordinates from the center of the display screen (or the player character to be moved). The scroll amount may be changed according to the distance up to 50. Typically, the scroll amount per frame may be increased as the distance from the center of the display screen to the current input coordinate 50 increases.
