  Hereinafter, a game executed based on the game program will be described. First, before explaining the detailed flow by this game program, in order to make an understanding of this invention easy, the outline | summary is demonstrated. In the present embodiment, an object appears in the game space according to a change in input given to the game space shown on the second display screen 12a. Specifically, the game program uses the two screens to display the same game space in which a predetermined gravity is set, and the first display screen 11a is displayed by the gravity regardless of the player's operation. A game space including a free-falling player character PC is displayed. And the game space located in the downward direction with respect to the game space displayed on the 1st display screen 11a is displayed on the 2nd display screen 12a. In the game space displayed on the first display screen 11a and the second display screen 12a, an obstacle object OB appears in accordance with a change in input given to the game space shown on the second display screen 12a. The obstacle object OB can inhibit the movement of the player character PC, and the movement direction of the player character PC is changed based on the movement direction of the player character PC in contact with the obstacle object OB. In this embodiment, the game field GF is used as the game space.

  Next, specific examples of the game will be described with reference to FIGS. FIG. 3 is a diagram showing the relationship between the game field GF and the first display area and the second display area. FIG. 4 is an example of a game image displayed on the first display screen 11a and the second display screen 12a by the game program. FIG. 5 is an example of a screen in which an obstacle object OB appears in the game field GF displayed on the second display screen 12a when an input change is given to the second display screen 12a. FIG. 6 is an example of a screen in which an obstacle object OB that appears in the game field GF displayed on the second display screen 12a is displayed on the first display screen 11a. FIG. 7 is an example of one screen in which the moving direction of the player character PC in the game field GF is changed by the obstacle object OB. FIG. 8 is an example of a screen in which the moving direction of the enemy character EC in the game field GF is changed by the obstacle object OB. FIG. 9 is an example of a screen on which the movement of the enemy character EC in the game field GF is stopped by the obstacle object OB.

  As shown in FIG. 3, the entire map of the game field GF is provided with a background image, and game field coordinates (x, y) are set. The free fall direction set in the game field GF is defined as the y-axis direction, and the lateral direction perpendicular to the y-axis direction is defined as the x-axis direction. A player character PC, an obstacle object OB, and an enemy character EC, which will be described later, are arranged in the game field GF based on the game field coordinates (x, y), respectively.

  A part of the game field GF is set in the first display area and the second display area. Then, the game field GF included in the first display area is displayed on the first display screen 11a, and the game field GF included in the second display area is displayed on the second display screen 12a. In the first display area, display reference coordinates (x1, y1) are set at the upper left position, and the first display area is arranged on the game field coordinate plane according to the display reference coordinates (x1, y1). In the second display area, display reference coordinates (x2, y2) are set at the upper left position, and the second display area is arranged on the game field coordinate plane according to the display reference coordinates (x2, y2).

  As will be apparent from the description below, the first display area is set so that the player character PC is positioned at the predetermined position. That is, the display reference coordinates (x1, y1) of the first display area are set according to the arrangement position of the player character PC in the game field GF, and the first display area is also within the game field GF according to the movement of the player character PC. To move. Note that the relationship between the arrangement position of the player character PC and the display reference coordinates (x1, y1) is always constant (that is, the position where the player character PC is fixed in the first display area) in the description below. However, the positional relationship may be offset according to the movement of the player character PC.

  On the other hand, the second display area is set to an arrangement position that is paired with the first display area in the game field GF. Specifically, the second display area is always provided directly below the first display area with a certain interval. That is, the display reference coordinates (x2, y2) of the second display area are set as x2 = x1, y2 = y1 + a. Here, a is a constant.

  As shown in FIG. 4, a game image showing the state of the game field GF in the first display area is displayed on the first display screen 11a of the game apparatus 1. And the game image which shows the mode of the game field GF of a 2nd display area is displayed on the 2nd display screen 12a of the game device 1. FIG. The player character PC appearing in the game field GF is a hero character that freely falls on the game field GF at a predetermined speed regardless of the operation of the player. On the other hand, the enemy character EC (in FIG. 4, the enemy characters EC1 and EC2 are displayed as an example) is a character that freely moves in the game field GF and attacks the player character PC.

  As described above, the game field GF in the first display area in which the player character PC is always displayed is displayed on the first display screen 11a. Therefore, as the player character PC freely falls on the game field GF at a predetermined speed, the first display area displayed on the first display screen 11a also scrolls down the game field GF. Further, since the second display area displayed on the second display screen 12a is also set as a pair with the first display area, the game field GF is similarly scrolled downward. Therefore, on the first display screen 11a and the second display screen 12a, a game image in which the enemy character EC and the background image B arranged in the game field GF move upward relative to the player character PC. Expressed. In FIG. 4, the current enemy character EC and the background image B are indicated by solid lines, and the enemy character EC and the background image B before a predetermined time are indicated by broken lines, and all move upward as the predetermined time elapses. ing. The player character PC is indicated by the same solid line both at the present time and a predetermined time ago, and is arranged at a fixed position in the first display area. That is, the player character PC freely displays the game field GF by arranging and displaying the player character PC at a fixed position on the first display screen 11a and moving other images relatively upward. Expressing the state of falling.

  As shown in FIG. 5, an obstacle object OB appears at a position on the game field GF corresponding to an input given using the touch panel 13 covered on the surface of the second display screen 12a. Since the second display screen 12a is covered with the touch panel 13, a change in input given to the game field GF is detected by detecting an input of the touch panel 13 corresponding to the game field GF displayed on the second display screen 12a. Can be detected.

  For example, the player makes an input to the touch panel 13 that covers the second display screen 12 a with the stylus 16. In other words, an input instruction is given to the game field GF displayed on the second display screen 12a. In the game apparatus 1, by detecting this input in real time, touch panel coordinates for each predetermined time are obtained and converted into game field coordinates (x, y), respectively. Then, according to the respective game field coordinates (x, y), the obstacle object OB is arranged on the game field GF. In this embodiment, since the touch panel 13 is provided only on the second display screen 12a, the obstacle object OB can appear in the game field GF set in the second display area. Then, the obstacle object OB is arranged in the game field GF while being fixed to the game field coordinates (x, y) that have appeared.

  As shown in FIG. 6, on the first display screen 11a and the second display screen 12a, a game in which the obstacle object OB arranged in the game field GF also moves relatively upward with respect to the player character PC. An image is represented. In FIG. 6, the current obstacle object OB is indicated by a solid line, and the obstacle object OB before a predetermined time is indicated by a broken line. The player character PC is indicated by the same solid line both at the present time and a predetermined time ago, and is arranged at a fixed position in the first display area. That is, the obstacle object OB that has appeared in the game field GF set in the second display area becomes the first display area by scrolling the first display area and the second display area, and is displayed on the first display screen 11a. The player character PC or the enemy character EC is approached. In addition, the obstacle object OB disappears from the game field GF after a certain period of time.

  As shown in FIG. 7, when the player character PC comes into contact with the obstacle object OB, the obstacle object OB inhibits the movement of the player character PC, and the moving direction and moving speed of the player character PC in the game field GF change. To do. For example, when touching the obstacle object OB, the player character PC moves not only in the free fall direction but also in the left and right direction of the game field GF and in the upward direction against gravity. Moving. As described above, the movement of the player character PC can be indirectly operated by the obstacle object OB drawn by the player. In FIG. 7, the current obstacle object OB and the background image B are indicated by solid lines, and the obstacle object OB and the background image B before a predetermined time are indicated by broken lines. Has moved. The player character PC is indicated by the same solid line both at the present time and a predetermined time ago, and is arranged at a fixed position in the first display area. Thus, even if the player character PC moves in the left-right direction, the first display area displayed on the first display screen 11a scrolls in the opposite direction, and the player character PC is always displayed at the center position.

  As shown in FIGS. 8 and 9, when the enemy character EC comes into contact with the obstacle object OB, the obstacle object OB inhibits the movement of the enemy character EC, and the movement direction and movement of the enemy character PC in the game field GF. The speed changes. For example, as shown in FIG. 8, when the enemy character EC comes into contact with the obstacle object OB, the enemy character EC moves so as to be reflected with respect to the side of the contacted obstacle object OB. Also, as shown in FIG. 9, when the enemy character EC comes into contact with the obstacle object OB, the movement is temporarily stopped by the obstacle object OB that has come into contact. Thus, the movement of the enemy character EC can be disturbed by the obstacle object OB drawn by the player. In FIG. 8 and FIG. 9, the current obstacle object OB and the enemy character EC are indicated by a solid line, and the enemy character EC before a predetermined time is indicated by a broken line. In FIG. 8, the enemy character EC moves in the game field GF while reflecting on the obstacle object OB. In FIG. 8, the enemy character EC has stopped moving in the game field GF by the obstacle object OB.

  Next, the process executed by the game program will be specifically described with reference to FIGS. FIG. 10 is a flowchart showing processing executed by the game program. FIG. 11 is a subroutine showing detailed processing of the obstacle object drawing / erasing processing in step 33 of FIG.

FIG. 16 is a diagram illustrating an example in which the moving direction of the enemy character EC changes when contacting the obstacle object OB.

  First, when a power source (not shown) of the game apparatus 1 is turned on, a boot program (not shown) is executed by the CPU core 21, and thereby a game program stored in the cartridge 17 is loaded into the WRAM 22. . When the loaded game program is executed by the CPU core 21, the step shown in FIG. 10 (abbreviated as “S” in FIG. 10) is executed.

  First, the CPU core 21 sets default values such as a movement vector and an arrangement position indicating the moving direction and moving speed of the player character PC in the game field GF (step 31). Then, the CPU core 21 randomly sets default values such as a movement vector and an arrangement position indicating the moving direction and moving speed of the plurality of enemy characters EC in the game field GF, respectively (step 32), and the process is performed in the next step. Proceed to

  Next, the CPU core 21 performs a drawing / erasing process of the obstacle object OB (step 33), and performs a process relating to the player character PC (step 34) and the enemy character EC (step 35). The details of these steps 33 to 35 will be described later.

  Next, the first GPU 24 and the second GPU 26 operate according to instructions from the CPU core 21, and various image data such as the background image B, the obstacle object OB, the player character PC, and the enemy character EC included in the game program are read out. The game field GF in the first display area is drawn in the 1VRAM 23, and the game field GF in the second display area is drawn in the second VRAM 25 (step 36). A game image showing the state of the game field GF in the first display area is displayed on the first display screen 11a of the game apparatus 1, and the state of the game field GF in the second display area is shown on the second display screen 12a. A game image is displayed.

  As will be described later, the positions of the obstacle object OB, the player character PC, and the enemy character EC (game field coordinates (x, y)) in the game field GF are set by the processing in steps 33 to 35, respectively. ing. Then, the CPU core 21 sets the display reference coordinates (x1, y1) of the first display area so that the player character PC is arranged at a predetermined position (for example, the center) of the first display area. Further, the CPU core 21 sets the display reference coordinates (x2, y2) of the second display area so that the second display area is always provided directly below the first display area with a certain interval.

  In addition, although the relationship between the arrangement position of the player character PC and the display reference coordinates (x1, y1) is always constant, the positional relationship may be offset according to the movement action of the player character PC. Further, virtual cameras corresponding to the first display area and the second display area are set for the game field GF, and the viewpoints of the virtual cameras are moved, so that the first display area and the second display area Each game image showing the state of the game field GF may be drawn.

  Next, the CPU core 21 determines whether or not to end the game (step 37), and when continuing the game, returns to step 33 and repeats the process. On the other hand, when ending the game, the CPU core 21 ends the processing according to the flowchart. For example, when the game over process described later is performed, the player character PC reaches a target point in the game field GF, or the player performs an operation to end the game, the CPU core 21 ends the game. Judge that.

  Next, with reference to FIG. 11, the detailed processing of the obstacle object drawing / erasing processing in step 33 will be described. First, the CPU core 21 starts detecting input to the touch panel 13 (step 41). Next, the CPU core 21 determines whether or not there is an input from the touch panel 13 (step 42). Then, when there is an input from the touch panel 13, the CPU core 21 advances the processing to the next step 43. On the other hand, if there is no input from the touch panel 13, the CPU core 21 advances the processing to the next step 48.

  In step 43, the CPU core 21 detects the input touch panel coordinates. As shown in FIG. 14C, the touch panel 13 has a coordinate system (touch panel coordinates) corresponding to the coordinate system of the second display area displayed on the second display screen 12a, and includes a stylus 16, a player's finger, and the like. The position coordinate data corresponding to the position input (instructed) is output. That is, in step 43, the CPU core 21 detects position coordinates output from the touch panel 13 (including a device driver that controls the touch panel 13).

  Next, the CPU core 21 converts the detected touch panel coordinates into a coordinate system of the second display area as shown in FIG. 14B, and calculates an offset from the display reference coordinates of the second display area (step). 44). Then, the CPU core 21 detects the display reference coordinates (x2, y2) of the second display area set with respect to the game field coordinates (x, y) (step 45), and is calculated in step 44 above. The game field coordinates for the offset are calculated (step 46). Here, a coordinate system as shown in FIG. 14A is set in the first display area, and a coordinate system as shown in FIG. 14B is set in the second display area. The display reference coordinates of the first display area (coordinates (0, 0) shown in FIG. 14A) are set so that the player character PC is placed at a predetermined position of the first display area on the game field GF. Is done. Further, the display reference coordinates (the coordinates (0, 0) shown in FIG. 14B) of the second display area are directly below the first display area with the second display area always spaced apart on the game field GF. It is set to be provided in the direction. That is, the CPU core 21 sets the display reference coordinates of the first display area based on the game field coordinates of the player character PC, and sets the display reference coordinates of the second display area based on the display reference coordinates of the first display area. Set. Thus, the touch panel coordinates detected in step 43 are transformed into game field coordinates (x, y) corresponding to the touch panel coordinates by the processing in steps 43 to 46.

  Next, the CPU core 21 generates an obstacle object OB at the position of the game field coordinates (x, y) calculated in step 46 and places it on the game field GF (step 47). Proceed to step 48. The obstacle object drawing / erasing process is a subroutine that is processed at regular intervals, and when the player continues to input using the touch panel 13, the above steps 43 to 47 are also repeated at regular intervals. . Accordingly, the obstacle object OB appears in the game field GF every predetermined time, and a plurality of obstacle objects OB are generated according to the time for which the input is continued (see FIG. 5). The obstacle object OB may be in other modes. For example, the start point and the end point of the input performed by the player using the touch panel 13 may be detected, and a bar-like object connecting the start point and the end point may appear as the obstacle object OB.

  In step 48, the CPU core 21 determines whether or not there is an obstacle object OB that has passed for a fixed time after appearing in the game field GF. The game apparatus 1 has a timer for measuring the predetermined time, and the CPU core 21 determines the elapse of the predetermined time based on the timer. Then, the CPU core 21 erases the obstacle object OB after a certain time from the game field GF (step 49) and ends the subroutine. On the other hand, if there is no obstacle object OB for which a fixed time has passed, the CPU core 21 fixes and arranges the obstacle object OB in the game field GF as it is, and ends the subroutine.

  The obstacle object OB that has appeared in the game field GF is erased from the game field GF after a certain period of time by the processing in step 48 and step 49. Therefore, even if the player character PC stops on the game field GF in a state in which the movement of the obstacle object OB is obstructed, the obstacle object OB is eventually erased, so that the player character PC continues to play the game field GF. A free-falling action can be performed.

  Next, with reference to FIG. 12, the detailed process of the player character process in step 34 will be described. First, the CPU core 21 determines contact between the player character PC and the obstacle object OB on the game field GF (step 51), and determines whether or not they are in contact (step 52).

  When the player character PC and the obstacle object OB are in contact with each other, the CPU core 21 calculates the inclination of the side of the obstacle object OB at the contacted coordinate position (step 53). For example, as shown in FIG. 15, it is assumed that the player character PC touches at a point TP on the outer edge of the spherical obstacle object OB with the movement vector V1. In this case, the coordinate position where the point TP is in contact is the edge of the obstacle object OB at the coordinate position where the tangent S of the circle indicating the outer edge of the obstacle object OB including the point TP is in contact. In the example of FIG. 15, the side inclination is about 45 ° lower left.

  Next, the CPU core 21 calculates a new movement vector of the player character PC according to the movement vector of the player character PC and the inclination of the side (step 54), and advances the processing to the next step 56. For example, the movement vector of the new player character PC is calculated so as to be reflected with respect to the side, similarly to the enemy character EC described later. In the example of FIG. 15, a new movement vector V2 is calculated so that the movement vector V1 is reflected at the tangent S and the point TP.

  On the other hand, if it is determined in step 52 that the player character PC and the obstacle object OB are not in contact with each other, the CPU core 21 sets a new movement vector of the player character PC based on the free fall law in the game field GF. The movement vector of the player character PC is calculated (step 55), and the process proceeds to the next step 56. For example, as indicated by the movement vector V3 in FIG. 15, even if the player character PC is moving in the horizontal direction, the moving direction is gradually changed downward by the free fall law.

  In step 56, the CPU core 21 moves the position of the player character PC in the game field GF based on the new movement vector calculated in step 54 or 55, and new game field coordinates (x , Y). Next, the CPU core 21 determines whether or not the player character PC and the enemy character EC are in contact with each other on the game field GF (step 57). When the player character PC and the enemy character EC come into contact with each other, the CPU core 21 sets the game over (step 58), and ends the subroutine. On the other hand, if the player character PC and the enemy character EC are not in contact, the CPU core 21 ends the subroutine as it is.

  Next, detailed processing of the enemy character processing in step 35 will be described with reference to FIG. First, the CPU core 21 determines contact between the enemy character PC selected on the game field GF and the obstacle object OB (step 61), and determines whether they are in contact (step 62). Then, the CPU core 21 advances the process to the next step 63 when the player character PC and the obstacle object OB are in contact with each other. On the other hand, the CPU core 21 proceeds to the next step 66 when the player character PC and the obstacle object OB are not in contact with each other.

  In step 63, when the player character PC and the obstacle object OB are in contact, the CPU core 21 calculates the inclination of the side of the obstacle object OB at the coordinate position in contact. For example, as shown in FIG. 16, it is assumed that the enemy character EC touches at a point TP on the outer edge of the spherical obstacle object OB with the movement vector V1. In this case, the coordinate position where the point TP is in contact is the edge of the obstacle object OB at the coordinate position where the tangent S of the circle indicating the outer edge of the obstacle object OB including the point TP is in contact. In the example of FIG. 16, the slope of the side is a lower left drop of about 45 °.

  Next, the CPU core 21 calculates a straight line perpendicular to the side with the coordinate position in contact as the center (step 64). Then, the CPU core 21 calculates a new movement vector by reversing the direction with respect to the currently set movement vector using the straight line calculated in step 64 as the axis of line symmetry (step 65), The process proceeds to the next step 66. For example, in the example of FIG. 16, the step 64 calculates the straight line perpendicular to the side centered on the coordinate position where the straight line L is in contact. Then, with respect to the movement vector V1, a movement vector V2 in which the straight line L is axisymmetric axis and the direction is reversed is newly calculated. In FIG. 16, the broken enemy character EC shows a state before contact with the obstacle object OB, and the solid enemy character EC shows a state after contact with the obstacle object OB at the point TP.

  In step 66, the CPU core 21 moves the position of the enemy character EC in the game field GF based on the current movement vector, and sets new game field coordinates (x, y) for the player character PC. Next, the CPU core 21 determines whether or not the position on the game field GF of the enemy character EC moved in step 66 has deviated from the first display area to the upper side (step 67). The position deviated upward from the first display area is a position that is not included in the first display area even if the first display area scrolls left or right or down from the current setting position of the game field GF. Yes, it means a position that is out of an area that is not represented as a game image again. If the CPU core 21 is out of the first display area, the CPU core 21 deletes the enemy character EC from the game field GF (step 68), and proceeds to the next step 69. On the other hand, if the CPU core 21 does not move upward from the first display area, the CPU core 21 proceeds to the next step 69 as it is.

  In step 69, the CPU core 21 determines whether or not the game field coordinates for which the first display area and the second display area are set have reached the enemy character appearance coordinates. When the enemy character appearance coordinates are reached, the CPU core 21 sets and sets a new enemy character EC in an area deviated from the second display area to the lower side (step 70), and the process proceeds to the next step 71. Proceed to The area deviating from the second display area to the lower side means that when the first display area and / or the second display area is scrolled down from the current set position of the game field GF, the first display area and / or It is a position that is scheduled to be included in the second display area, and means an area that can be expressed as a game image by continuing the game. On the other hand, if the enemy character appearance coordinates have not been reached, the CPU core 21 proceeds directly to the next step 71.

  In step 71, the CPU core 21 determines whether or not processing has been performed for all enemy characters EC arranged in the game field GF. If the unprocessed enemy character EC remains, the process returns to step 61 to select a new enemy character EC and repeat the process. On the other hand, when the processing is performed for all enemy characters EC, the processing according to the subroutine ends.

  In the above-described embodiment, as shown in FIG. 1, the game image in the first display area is displayed on the first display screen 11 a of the first LCD 11 that is physically two display devices, and the second display screen of the second LCD 12. Although the game apparatus 1 that displays the game image of the second display area on 12a has been described, the present invention is not limited to the game program executed on such a game apparatus 1. For example, it is a game device provided with a single physical display device, and the display screen of the display device may be used by dividing it into two vertically and horizontally. FIG. 17 shows a modified example of the game device that is provided with this single display device and that is divided into left and right parts. In addition, the same code | symbol is attached | subjected to the same structure as the Example mentioned above, and the detailed description is abbreviate | omitted.

  As shown in FIG. 17, the game apparatus 1 includes a single LCD 100 in place of the first LCD 11 and the second LCD 12 described above. The screen of the LCD 100 is divided into at least two display screens, a first display screen 100L and a second display screen 100R, by a game program or a monitor program. The second display screen 100R is covered with the touch panel 18.

  FIG. 18 is a screen example of a game image displayed on each of the first display screen 100L and the second display screen 100R by the game program. In the embodiment described above, the first display area and the second display area set above and below a part of the game field GF are displayed as game images. In this modified example, as shown in FIG. 18, a first display area and a second display area that are continuous to the left and right of a part of the game field GF are set. Then, the game field GF included in the first display area is displayed on the first display screen 100L, and the game field GF included in the second display area is displayed on the second display screen 100R. In the embodiment described above, the game progresses basically by moving downward on the game field GF based on the free fall of the player character PC. On the other hand, in this modified example, the player character PC basically rolls on the path R and moves to the right of the screen while following the gravity acting on the lower side of the screen.

  The player character PC appearing in the game field GF of the present modification is a hero character that rolls the game field GF rightward at a predetermined speed regardless of the operation of the player. A path R is set in the game field GF, and the player character PC rolls along the path R in the right direction on the screen. The first display screen 100L displays the game field GF in the first display area in which the player character PC is always displayed. Accordingly, as the player character PC moves in the game field GF at a predetermined speed, the game screen displayed on the first display screen 100L and the second display screen 100R also scrolls the game field GF rightward (FIG. 18). (A)).

  As shown in FIG. 18B, an object appears at a position on the game field GF corresponding to an input given using the touch panel 18 covered on the surface of the second display screen 100R. In the present modification, the guiding object OB appears as a freehand line segment at a position on the game field GF corresponding to an input given using the touch panel 18. In the present modification, since the touch panel 18 is provided only on the second display screen 100R, the guidance object OB can appear in the game field GF set in the second display area. Then, the guiding object OB is fixed to the appearing game field coordinates and arranged in the game field GF. Then, the player character PC rolls along the guidance object OB and moves on the game field GF (FIG. 18 (c)).

  For example, as shown in FIG. 18A, a gap is formed between the path R and the paths R1 and R2. If the player character PC continues to roll on the path R as it is, the player can pass through the gap. The character PC is expected to fall. Also, as shown in FIGS. 18A and 18B, an enemy character EC is arranged on the path R2, and if the player guides the player character PC to the path R2, the player character PC becomes the enemy character. Expect to encounter EC. Accordingly, as shown in FIG. 18B, the player creates a guiding object OB that connects the path R to the path R1 in order to continue the movement of the player character PC while avoiding encountering the enemy character EC. Eventually, as shown in FIG. 18C, when the player character PC reaches the position of the guidance object OB created by the player, the player character PC is guided from the path R to the path R1 along the guidance object OB.

  Further, when the player character PC and the guiding object OB come into contact, the player character PC expresses reactions such as “acceleration”, “deceleration”, and “bounce” according to the shape of the line drawn by the player. That is, the guidance object OB, which is a freehand line segment drawn by the player, is processed as terrain in real time in the same manner as other routes R.

  It should be noted that the guiding object OB of the present modification may also disappear after a certain period of time as in the above-described embodiment. For example, it may disappear gradually from the start point where the guiding object OB is drawn to the end point, or may disappear simultaneously from the start point to the end point.

  In this manner, a player character that moves on the game screen regardless of the player's operation appears, and the player character can be indirectly operated by drawing an object that becomes an obstacle or a guide in the game field. . Therefore, since the picture drawn by the player affects the movement of the player character, the player can enjoy the enjoyment that he / she is directly involved in the game world. The screen is always scrolled in a certain direction, and the object is automatically erased when a certain time elapses, so that the game screen is not filled with the drawn pattern.

  Also, the first display area for displaying the player character and the second display area for generating the object are separately divided, and the generated object scrolls from the second display area to the first display area. On the other hand, the object is drawn at a far position. Therefore, it takes time for the object to affect the movement of the player character, and the object must be drawn by estimating the movement of the player character and the surrounding situation until the object scrolls and reaches the position of the player character. In other words, it is possible to enjoy the joy of operating the player character indirectly by improving the strategy.

  If such an effect is not expected, a game device that displays a game image on the display screen of one physical display device covered with a touch panel may be used. In this case, a game field including both the first display area and the second display area described above is displayed on the display screen. The player can input the game field displayed on the display screen using the touch panel, and can generate an object even near the display position of the player character.

  Further, according to the present invention, by using the touch panel, the player can obtain a feeling directly related to the game space over a wide range. However, in the case where such an effect is not expected, in a game apparatus without a touch panel. Is also applicable. For example, if the player designates a position in the game space by operating a mouse or a cross key and generates an object at the position, a similar game can be realized.

  The present invention can realize a game in which a picture or the like drawn by a player affects the action of the player character, and the game is progressed to a game device having an operation device such as a touch panel and at least one display screen. It is useful as a game program and its game device.
