  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 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.

  FIG. 3 shows a memory map of the RAM 24. The RAM 24 stores a game program 40, character information 42, background information 44, selection display circle image data 46, operation locus element image data 48, current input coordinates 50, and operation locus information 52.

  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 characters in the game world. Examples of the character include a player character that can be operated by the player and an enemy character that is automatically operated by a computer. The character information 42 includes image data of each character in the game world, current position information of each character, and status information of each character. The image data is read from the ROM 17a into the RAM 24 and used for generating a game image. Current position information and status information are updated as needed as the game progresses.

  The background information 44 is information relating to the ground and obstacles that constitute the background of the game world. The background information also includes position information and image data.

  The selection display circle image data 46 is a circle or a circle displayed on the screen so as to surround the selected player character when one or more player characters (for example, PC1 to PC3 in FIG. 5) are selected as an operation target by the player. This is image data of an ellipse (see 54 in FIG. 7). Hereinafter, this circle (or ellipse) image is referred to as a selective display circle image. By appropriately setting the radius value of the selection display circle image data 46, a selection display circle image having an arbitrary size can be generated.

  The operation trajectory element image data 48 is image data for generating an image of a trajectory when the player slides the stick 16 on the touch panel 15 (hereinafter referred to as an operation trajectory). This is rectangular polygon data. By appropriately setting the length and width values of the operation trajectory element image data 48, it is possible to generate an operation trajectory element image having an arbitrary square shape.

  The current input coordinates 50 are coordinates indicating the contact position of the stick 16 on the touch panel 15, and are updated at any time based on an output signal from the touch panel 15.

  The operation locus information 52 is information indicating a transition history of the contact position of the stick 16 on the touch panel 15. For example, when the player slides the stick 16 on the touch panel 15, the shape of the locus is stored as the operation locus information 52. By using the operation locus information 52, for example, it can be determined whether or not the player has slid the stick 16 so as to surround the character displayed on the screen. Details of the operation locus information 52 will be described later (FIGS. 16 to 20).

  Next, an outline of a game executed based on the game program 40 will be described with reference to FIGS.

  When the game is started, the state of the game world is displayed on the second LCD 12 as shown in FIG. In the game world, there are five player characters PC1 to PC5 and one enemy character EC. The player characters PC1 to PC5 are characters that can be operated by the player, and the enemy character EC is a character that is automatically controlled by a computer. However, the player characters PC1 to PC5 are controlled to move by the computer as if they were acting at their own will when the player is not performing any input operation. For example, one player character is dozing and another player character is running around the game world. However, the configuration may be such that the movement control by the computer is not performed when the player is not performing any input operation.

  The player can select any one or more of the five player characters PC1 to PC5 as an operation target. As shown in FIG. 5, this selection operation is performed by surrounding the player character desired to be operated with the stick 16 (more precisely, the stick 16 on the touch panel 15 so as to surround the display position of each player character desired to be operated). Slide). When a mouse is used instead of the touch panel 15 as the coordinate input means, the pointer displayed on the screen may be moved so as to surround the player character to be operated while pressing the mouse button.

  When the selection operation as described above is performed, as shown in FIG. 6, the position of the center of gravity of the player character (hereinafter referred to as the operation target character) selected as the operation target, that is, the coordinate value of the operation target character is displayed for each coordinate axis. The selection display circle image 54 is displayed at the position indicated by the coordinates obtained by averaging, and the operation target character starts moving toward the inside of the selection display circle image 54. As a result, as shown in FIG. 7, the operation target characters gather together and wait for an instruction from the player. Thereafter, the player can give a movement instruction, an attack instruction, or a dissolution instruction to the operation target character through the touch panel 15.

  The movement instruction can be performed by touching the selection display circle image 54 with the stick 16 and then sliding the stick 16 as shown in FIG. When a movement instruction is given from the player, each operation target character starts moving toward the current touch position TP. Since there are individual differences in the moving speed of each player character, as shown in FIG. 9, there are player characters (PC3, PC4) that arrive immediately at the current touch position TP, and player characters that do not arrive easily (PC3, PC4). PC2). When the player moves the stick 16 away from the touch panel 15 while the operation target character is moving toward the current touch position TP, the movement instruction is canceled and the operation target character is near the center of gravity at that time. Are gathered together to wait for the player's instruction.

  The selection display circle image 54 is also displayed during the movement operation as described above, but the color of the selection display circle image 54 is changed during the movement operation and when the operation target character is waiting for an instruction from the player. It may be changed. Thus, for example, even when the stick 16 is momentarily separated from the touch panel 15 during the movement operation and the movement instruction is unexpectedly released, the player may immediately notice this by the color of the selection display circle image 54. it can.

  The attack instruction can be given by surrounding the enemy character EC with the stick 16 as shown in FIG. 10 during the movement operation (that is, when the stick 16 is slid as shown in FIG. 8). When an attack instruction is given from the player, the designation of the operation target is canceled (that is, the state returns to the state where the operation target character does not exist), and the player characters PC2 to PC4 given the attack instruction stick as shown in FIG. The enemy character EC surrounded by 16 is attacked. Note that the selection display circle image 54 is not displayed on the screen when the designation of the operation target is cancelled.

  The dissolution instruction is an instruction to cancel the designation of the operation target, and can be performed by sliding the stick 16 across the selection display circle image 54 as shown in FIG. When the designation of the operation target is canceled by the dissolution instruction, the player characters P2 to P4 again act arbitrarily as shown in FIG.

  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 S34 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.

  In step S14, an operation track information update process is performed. Hereinafter, the details of the operation trajectory information update processing will be described with reference to the flowchart of FIG.

(Operation track information update process)
In step S40 of FIG. 14, the remaining valid time of each input coordinate in the operation trajectory information 52 is updated. Since no input coordinates exist in the operation locus information 52 from when the game is started until the player touches the touch panel 15 for the first time, no processing is performed in step S40. The remaining valid time of the input coordinates will be described later.

  In step S42, it is determined whether or not the input coordinate is detected in step S12 of FIG. 13. If the input coordinate is detected, the process proceeds to step S44. If the input coordinate is not detected, the operation trajectory information update process is performed. And the process proceeds to step S16 in FIG.

  In step S44, the input coordinates detected in step S12 of FIG. 13 (that is, the current input coordinates 50) are the same as the input coordinates detected immediately before that (that is, the latest input coordinates stored in the operation trajectory information 52). If they are the same, the operation trajectory information update process is terminated and the process proceeds to step S16 in FIG. 13; otherwise, the process proceeds to step S46.

  Note that the processing in step S44 described above is performed so that when the same input coordinates are successively detected, these input coordinates are not stored in the operation trajectory information 52 in order to save the storage area of the RAM 24. However, the present invention is not limited to this. That is, the detected input coordinates may be sequentially stored in the operation trajectory information 52 unconditionally without performing the determination in step S44.

  In step S46, the input coordinates detected in step S12 of FIG.

  In step S48, the remaining effective time of the input coordinates newly stored in the operation trajectory information 52 in step S46 is set to an initial value (for example, 10).

  A specific processing example of the operation trajectory information update processing will be described with reference to FIGS.

  FIG. 15 shows an example of input coordinates detected in step S12 of FIG. 13 in the processing of each frame after the game starts. In the example of FIG. 15, the input coordinates are not detected in the first frame and the second frame, the input coordinates (X1, Y1) are detected from the third frame to the fifth frame, and input from the sixth frame to the 18th frame. The coordinates change every frame, and the input coordinates are not detected in the 19th and 20th frames. In the third frame, the player touches the touch panel 15 with the stick 16, the player slides the stick 16 on the touch panel 15 from the sixth frame to the eighteenth frame, and the player moves the stick 16 from the touch panel 15 in the nineteenth frame. It means having been released.

  16 to 20 show how the operation trajectory information 52 changes when the input operation as shown in FIG. 15 is performed.

  In the third frame, the input coordinates (X1, Y1) are detected in step S12 of FIG. Then, as shown in FIG. 16, the input coordinates (X1, Y1) are stored in the operation trajectory information 52 by the process of step S46 of FIG. For convenience, this input coordinate is referred to as input coordinate P1. Further, the remaining effective time of the input coordinate P1 is set to an initial value (here, 10) by the process of step S48 of FIG.

  In the fourth frame, the input coordinates (X1, Y1) are detected in step S12 of FIG. And the remaining effective time of the input coordinate P1 is updated to 9 by the process of step S40 of FIG. Note that the input coordinates (X1, Y1) detected in step S12 of FIG. 13 are the same as the input coordinates P1, and therefore are not added to the operation trajectory information 52.

  In the fifth frame, the input coordinates (X1, Y1) are detected in step S12 of FIG. Then, the remaining valid time of the input coordinate P1 is updated to 8 by the process of step S40 of FIG. Note that the input coordinates (X1, Y1) detected in step S12 of FIG. 13 are the same as the input coordinates P1, and therefore are not added to the operation trajectory information 52.

  In the sixth frame, the input coordinates (X2, Y2) are detected in step S12 of FIG. And the remaining effective time of the input coordinate P1 is updated to 7 by the process of step S40 of FIG. Further, as shown in FIG. 17, the input coordinates (X2, Y2) are stored in the operation trajectory information 52. For convenience, this input coordinate is referred to as input coordinate P2. Further, the remaining effective time of the input coordinate P2 is set to an initial value (here, 10) by the process of step S48 of FIG.

  In the seventh frame, the input coordinates (X3, Y3) are detected in step S12 of FIG. Then, the remaining valid times of the input coordinates P1 and P2 are updated to 6 and 9, respectively, by the process of step S40 of FIG. Furthermore, as shown in FIG. 18, the input coordinates (X2, Y2) are stored in the operation trajectory information 52. For convenience, this input coordinate is referred to as input coordinate P3. Furthermore, the remaining effective time of the input coordinate P3 is set to an initial value (here, 10) by the process of step S48 of FIG.

  Thereafter, in the same manner, the update of the remaining valid time and the addition of new input coordinates are repeated.

  FIG. 19 shows the state of the operation trajectory information 52 at the time when the processing of the 13th frame is finished. At this time, the remaining valid time of the input coordinate P1 is 0, which indicates that the input coordinate P1 has become invalid. Similarly, FIG. 20 shows the state of the operation trajectory information 52 at the time when the processing of the 16th frame is finished. At this time, in addition to the input coordinate P1, the remaining valid time of the input coordinate P2 is also 0, which indicates that the input coordinates P1 and P2 have become invalid. The input coordinates that have become invalid may be deleted from the RAM 24 as necessary.

  As described above, in the operation trajectory information update process, input coordinates are sequentially added to the operation trajectory information 52, and on the other hand, 10 frame periods (the screen of the second LCD 12 is displayed 10 times) after being stored in the operation trajectory information 52. The input coordinates for which the period until the update has elapsed are sequentially invalidated.

  In the present embodiment, the initial value of the remaining effective time is set to 10, but this is merely a value for convenience of explanation, and the present invention is not limited to this. As is clear from the above description, the initial value of the remaining effective time affects the time until the input coordinates stored in the operation trajectory information 52 become invalid, so that the value greatly affects the operability. become. Therefore, the remaining effective time should be set to a value that can provide good operability. Note that the initial value of the remaining effective time may be arbitrarily set by the player, or the initial value of the remaining effective time may be automatically and appropriately changed during game play. Further, the initial value of the remaining effective time may be changed at any time according to the operation trajectory information 52 (for example, according to the change amount or change direction of the input coordinates).

  When the operation trajectory information update process in FIG. 13 ends, the CPU core 21 executes the operation trajectory image generation process in step S16. Hereinafter, the details of the operation trajectory image generation processing will be described with reference to the flowchart of FIG.

(Operation locus image generation processing)
In step S50 of FIG. 21, one input coordinate is selected from the input coordinates included in the operation locus information 52. Here, it is assumed that the time stored in the operation trajectory information 52 is sequentially selected from the newest to the oldest. Therefore, immediately after the operation trajectory image generation process is started, the newest input coordinate among the input coordinates included in the operation trajectory information 52 is selected.

  In step S52, it is determined whether or not the remaining valid time of the input coordinates selected in step S51 is 0. If it is 0, the operation trajectory image generation process is terminated and the process proceeds to step S18 in FIG. If not, the process proceeds to step S54.

  In step S54, the width of the operation trajectory element image is determined according to the remaining valid time of the input coordinates selected in step S51.

  In step S56, the input coordinates selected in step S51 and the input coordinates stored in the operation locus information 52 immediately before the input coordinates (that is, the input coordinates next to the input coordinates selected in step S51). An operation trajectory element image is placed between them.

  In step S58, it is determined whether or not there is an input coordinate (that is, an unprocessed input coordinate) not selected in step S50 in the operation trajectory information 52, and if it exists, the process returns to step S50. If it does not exist, the operation trajectory image generation process is terminated, and the process proceeds to step S18 in FIG.

  As described above, the processes of steps S54 and S56 are performed for all valid input coordinates included in the operation trajectory information 52. Here, with reference to FIGS. 22-25, the specific example of the process of said step S54 and step S56 is demonstrated.

  22 is stored in the operation trajectory information 52, the remaining effective time of the input coordinate Pa is 7, the remaining effective time of the input coordinate Pb is 8, and the remaining effective time of the input coordinate Pc is 9. Assume that the remaining effective time of the input coordinate Pd is 10. At this time, in step S50, the input coordinate Pd is first selected, and in the subsequent step S54, as shown in FIG. 23, the width of the operation trajectory element image arranged between the input coordinate Pc and the input coordinate Pd is 10 (input). The remaining effective time of the coordinate Pd) is determined, and in the subsequent step S56, the operation locus element image is arranged between the input coordinate Pc and the input coordinate Pd.

  In the next step S50, the input coordinate Pc is selected, and in the subsequent step S54, as shown in FIG. 23, the width of the operation trajectory element image arranged between the input coordinate Pb and the input coordinate Pc is 9 (input coordinate In the subsequent step S56, the operation trajectory element image is arranged between the input coordinates Pb and the input coordinates Pc.

  By repeating the same processing, an image as shown in FIG. 25 is finally obtained.

  In this embodiment, a rectangular shape is used as the operation trajectory element image, but the present invention is not limited to this. For example, a trapezoidal operation locus element image as shown in FIG. 24 may be used. In the example of FIG. 24, for example, the width of the operation trajectory element image arranged between the input coordinate Pc and the input coordinate Pd is changed from 9 (the remaining effective time of the input coordinate Pc) to 10 (the remaining effective time of the input coordinate Pd). The operation locus element image gradually changes. Thereby, the contour of the image of the operation locus becomes smoother.

  When the operation trajectory image generation processing in FIG. 13 is completed, the CPU core 21 uses an operation trajectory (hereinafter simply referred to as an effective operation trajectory) constituted by a valid input coordinate group included in the operation trajectory information 52 in step S18. It is determined whether or not the player character is surrounded. If it is determined that the player character is surrounded, the process proceeds to step S20. If not, the process proceeds to step S22. A method for determining whether or not the player character is surrounded by an effective operation locus is arbitrary. For example, whether the line segments connecting the valid input coordinates included in the operation trajectory information 52 in the order stored in the operation trajectory information 52 intersect each other (that is, a closed region is formed by the valid operation trajectory). If a closed region is formed by an effective operation locus, it is further determined whether or not a player character exists inside the closed region.

  In step S20, the player character surrounded by the effective operation locus is set as the operation target character, and the movement target point of each operation target character is set so that these operation target characters gather together to form a party. . Specifically, the same number of movement target points as the number of operation target characters are set in the selection display circle image 54 shown in FIG. As a result, each operation target character starts moving toward the movement target point closest to its current position, and finally enters a state as shown in FIG. 7 (for example, after 60 frames).

  In step S22, it is determined whether or not the enemy character is surrounded by an effective operation locus during the moving operation as shown in FIG. 10. If the enemy character is surrounded by an effective operation locus, the process proceeds to step S24. Proceed to step S26.

  In step S24, the enemy character surrounded by the valid operation trajectory is set as the attack target of the party member who has been moving.

  In step S26, it is determined whether or not the selection display circle image 54 has been crossed by an effective operation locus as shown in FIG. 12. If the selection display circle image 54 has been crossed by an effective operation locus, the process proceeds to step S28. Proceed to S30.

  In step S28, the designation of the operation target is canceled and the party formed in step S20 is dissolved.

  In step S30, various processes necessary for the progress of the game, such as the movement process of each character, the animation process of each character, the update of parameters indicating the state of each character, the generation of game sound, the scroll process of the screen, and the like. Process.

  In step S32, a game image including the operation locus image generated by the operation locus image generation processing in step S16 is generated, and the game image is displayed on the second LCD 12.

  In step S34, 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.

  As described above, according to the present embodiment, input coordinates that have been stored for a period of time after being stored in the operation locus information are sequentially invalidated, and an operation locus constituted by valid input coordinates is used for the game process. . Therefore, for example, when the player character or enemy character is surrounded by the stick 16 at a slow speed, the selection instruction and the attack instruction are not input. Thereby, it is possible to suggest to the player that it is necessary to surround the player character and the enemy character more quickly in order to input the selection instruction and the attack instruction described above. In the present embodiment, the reason why the quick input operation is requested for the selection instruction, the attack instruction, and the dissolution instruction is that these instructions are accidentally input against the player's intention (for example, the intention during the movement operation) This is to prevent an attack instruction or a dissolution instruction from being input without

  In addition, according to the present embodiment, the operation trajectory configured by the valid input coordinates stored in the operation trajectory information is displayed on the screen, so that the player can easily grasp the shape of the current effective operation trajectory. can do.

  In addition, according to the present embodiment, the width of the operation locus displayed on the screen partially changes according to the remaining effective time of the input coordinates constituting the operation locus, so that the player is displayed on the screen. It is possible to intuitively understand how long each part of the operation trajectory is invalidated. For example, in the example of FIG. 26, it is determined how long the input coordinates will become invalid from the width of the operation locus at the input coordinates (stick contact position represented by a wavy line) when the player starts coordinate input. I can understand to some extent.

  FIG. 27 is an example in which an input operation is performed at an appropriate speed, and FIG. 28 is an example in which the input operation fails. When the input operation fails, the player can confirm how fast the input operation should have been performed from the image of the operation locus at that time.

  In the present embodiment, the width of the operation locus is partially changed according to the remaining effective time of the input coordinates, but the present invention is not limited to this. For example, the color and transparency of the operation locus may be partially changed according to the remaining effective time of the input coordinates. As a preferred example, as the remaining effective time of the input coordinates decreases, the color of the portion of the operation locus corresponding to the input coordinates is reduced. As a method of making the color lighter, the color of the operation track image itself is changed to a lighter color, or the color of the operation track image is apparently lightened by dithering, or the parameter indicating the transparency of the operation track image is changed. The method to do is mentioned.
