Description

  The present invention relates to a game program and a game device, and more specifically, to a second display screen by being executed by a computer of a game device including a first display screen and a second display screen covered with a touch panel. The present invention relates to a game program for changing a game image in accordance with a change in input, and the game apparatus.

  In a conventional game device, a state in the game space is displayed as a game image on a television or the like. To this game device, a controller provided with a plurality of operation keys is connected in order for the player to operate a character appearing in the game space. The game device detects an output signal from the controller to determine which operation key is operated by the player, and reflects the action assigned to the operation key on the character. The image is changing.

  However, since the shape and arrangement of the operation keys provided on the controller are physically determined, it is impossible to prepare an optimal operation key corresponding to the game. For this reason, game devices that use a display device with a touch panel or a tablet instead of a controller have appeared (for example, see Patent Documents 1 to 4).

  As shown in FIG. 3 of Patent Document 1, the game device disclosed in Patent Document 1 displays an image of operation keys necessary for each game program on a touch panel. Depending on which operation key image is selected by touching, the function corresponding to the operation key image is reflected in the game.

  As shown in FIGS. 3 to 8 of Patent Document 2, the game device disclosed in Patent Document 2 displays a graphic and characters related to a game image displayed on a television on a touch panel on the controller side. Displayed on the device. Then, by selecting the symbol by touching it with a finger, the function corresponding to the symbol or character is reflected in the game.

  In the game device disclosed in Patent Document 3, as shown in FIG. 6 of Patent Document 3, a game screen is displayed on a display to which a touch panel is attached. Then, the target selected by touching is moved on the game screen with a motion corresponding to the vector amount of the finger motion touched on the touch panel by the player.

As shown in FIG. 2 of Patent Document 4, the game device disclosed in Patent Document 4 is configured by integrally arranging a tablet and a flat display so that the game is displayed on the flat display. A golf course is represented as an image. Then, the flight of the virtual sphere is simulated with the direction of the coordinate sequence corresponding to the trajectory input by the player using the pen on the tablet as the batting direction and the interval between adjacent coordinates in the coordinate row as the batting force.

  However, in the game devices disclosed in Patent Documents 1 and 2 described above, it is determined only whether or not a symbol displayed on the display device under the touch panel on the controller side is selected, and the function corresponding to the symbol is a game. It was only reflected in the image. That is, conventional operation keys provided physically are simply displayed on the display device under the touch panel, and the operation keys can be simply displayed in free positions and shapes according to the type of game. There was a problem that only an effect could be expected.

  In addition, in the game devices disclosed in Patent Documents 3 and 4 described above, the player aims to move an image displayed superimposed on the touch panel or the tablet to a desired position on the game image. When is small, it becomes difficult for the player to accurately instruct the desired movement. In addition, since an object such as a player character that the player moves on the game image using a touch panel or a tablet may be hidden by the operation of the player, the game's interest to enjoy the movement of the player character is impaired. There is.

  A touch panel is also used for a personal digital assistant (PDA) or the like, and a system in which a user directly operates a symbol displayed on a liquid crystal display device covered with the touch panel is adopted. Specifically, in a PDA or the like, a folder is opened by “double-clicking” on a design such as a folder, or an icon is moved by “dragging” a design such as an icon. That is, in PDA and the like, since it is premised that the user-desired operation is surely performed, the directly touched design changes its display mode. However, when such a technique is simply diverted to an electronic game, the display mode of the player character that can be directly operated by the player is changed. Also changes, making it impossible to identify the player character itself. For example, it is assumed that symbols of a plurality of triangular operation keys and a circular operation key are displayed on a display unit covered with a touch panel. When the display operation of the circular operation key changes to a triangular shape by touching the circular operation key, the player determines which operation key is the operation key that was originally circular. I don't know.

  Therefore, an object of the present invention is to allow a player to accurately input a symbol using the touch panel with respect to the symbol displayed on the second display screen covered with the touch panel, and to improve its operability. It is to provide a game program and a game apparatus capable of changing a game image displayed on the first display screen in accordance with the input while ensuring.

  In order to achieve the above object, the present invention employs the following configuration. Note that reference numerals in parentheses, step numbers (steps are abbreviated as S and only step numbers are described), supplementary explanations, and the like have shown correspondences with embodiments described later in order to help understanding of the present invention. However, it does not limit the scope of the present invention.

  The game program of the present invention is executed by a computer (21 etc.) of the game apparatus (1) including the first display screen (11a) and the second display screen (12a) covered with the touch panel (13). The game program includes a computer, first game image display control means (S21, S51), second game image display control means (S22, S52), input detection means (S23, S27, S28, S53, S57, S58), It functions as change condition calculation means (S24, S26, S29, S31, S54, S56, S59, S61) and player character control means (S32, S62). The first game image display control means displays a first game image including a player character (P1) to be operated by the player on the first display screen. The second game image display control means displays on the second display screen a second game image for displaying a character symbol (P2) corresponding to the player character larger than the player character in the first game image. The input detection means detects an input position (input coordinates) touch-operated on the touch panel and an input change thereof (for example, a continuous series of input coordinate changes). When the change condition calculation means is on the character design displayed on the second display screen at least a part of the input position detected by the input detection means (start point, end point, position coordinates of some or all intermediate points) Then, change condition data (movement direction, speed, Ryukyu mode, etc.) for changing the display mode (movement, etc.) of the player character according to the input position on the character design and the input change detected by the input detection means are calculated. To do. The player character control means changes the display mode of the player character based on the change condition data.

  The change condition calculation means divides the detection area (P3) of the touch panel corresponding to the character symbol displayed on the second display screen into a plurality of definition regions (Z1 to Z4), and includes a definition region including an input position on the character symbol Depending on, different types of operation parameters (Ryukyu mode) may be calculated as change condition data (S84).

  For example, the player character is a moving body that moves in the game space. In this case, the change condition calculation means calculates initial movement condition data (movement amounts gStepX and gStepY, speed gSpeed) and movement change condition data (flag for setting the Ryukyu mode, curve coefficient k) as the change condition data. The change condition calculation means calculates initial movement condition data for determining the initial movement direction of the moving object in the game space based on the direction of the input change (S86, S87, S89). The change condition calculating means calculates movement transition condition data for changing the moving direction of the moving object in the game space after starting to move in the initial moving direction based on the input position on the character symbol (S84, S91, S155).

  The input change detection means determines the presence or absence of input to the touch panel at regular time intervals, and detects the input position and the input change by detecting the position coordinates on the touch panel while the input is continuously detected. It does not matter if it is detected. Then, the change condition calculation means extracts the position coordinates at the input start time and the input end time for the touch panel successively detected by the input change detection means, respectively, and changes according to the position coordinates at the input start time and the input end time. The condition data may be calculated.

  For example, the player character is a moving body that moves in the game space. In this case, the change condition calculation means calculates initial movement condition data and movement change condition data as the change condition data. The change condition calculation means is for determining the initial moving direction and speed of the moving object in the game space based on the direction from the position coordinate at the start of input (start point S) to the position coordinate at the end of input (end point E). Initial movement condition data is calculated. The change condition calculation means divides the detection area of the touch panel corresponding to the character design displayed on the second display screen into a plurality of definition areas, and calculates the position coordinates at the input start time and the position coordinates at the input end time on the character design. In accordance with the definition area including at least one, movement transition condition data for changing the movement direction of the moving object in the game space after the movement is started in the initial movement direction is calculated.

  The change condition calculation means sets the detection area of the touch panel corresponding to the character symbol displayed on the second display screen to a plurality of definition areas according to the direction from the position coordinates at the input start time to the position coordinates at the input end time. You may divide | segment (FIG. 8, S101-S105, S107, S109-S111, S113).

  In addition, the change condition calculation means includes a predetermined reference position (center of P2) included in the detection area of the touch panel corresponding to the character symbol displayed on the second display screen, the position coordinates at the input start time, and the input end time. Depending on the distance from the straight line (SE) including the position coordinates, the movement transition condition data may be calculated (S91) so that the amount of change for changing the moving direction of the moving body increases.

  The input change detection means detects the input position and the input change by determining the presence or absence of input to the touch panel at regular time intervals and detecting the position coordinates on the touch panel while the input is continuously detected. It doesn't matter. The game program may further cause the computer to function as time measuring means (S30, S60) for measuring the input detection time while the input changing means continuously detects the input. In this case, the change condition calculation means extracts the position coordinates at the input start time and the input end time for the touch panel continuously detected by the input change detection means, respectively, and the position coordinates at the input start time and the position coordinates at the input end time. And change condition data is calculated according to at least two of the input detection times.

  The input change detection means detects the input position and the input change by determining the presence or absence of input to the touch panel at regular time intervals and detecting the position coordinates on the touch panel while the input is continuously detected. It doesn't matter. The game program is a single program that shows the relationship between the position coordinates (point N) being input to the touch panel and the position coordinates at the start of input while the input change detecting means continuously detects the input. The computer may further function as figure generation means (S73, S74) for generating a figure (isosceles triangle Tr, line segment, arrow, etc.). In this case, the second game image display control means displays a second game image further including the graphic generated by the graphic generating means on the second display screen (FIG. 7).

  For example, the graphic generated by the graphic generation means is an isosceles triangle (Tr) having the input position coordinate as the apex and the input start time position coordinate as the midpoint of the base of a predetermined length (2L).

  The game apparatus of the present invention includes a storage means (22), a first display screen, a second display screen covered with a touch panel, and a game execution means (21 and the like). The storage means stores any of the game programs described above. The game execution means executes the game program stored in the storage means.

  According to the game program of the present invention, since the display mode of the player character on the first display screen changes according to the change of the touch panel input given to the character design, it is possible to provide a game with an unprecedented operational feeling. Can do. In addition, since the character design corresponding to the player character is displayed larger than the player character on the second display screen, it is possible to indicate the player's desired location relatively accurately. In addition, a player character whose display mode changes is displayed on the first display screen, and the player's operation is performed on the character design displayed on the second display screen, so that the player character is hidden by the player's touch operation. This can be prevented. Furthermore, since the display mode of the player character on the first display screen is changed according to the relatively accurate input position and input change with respect to the character design, and the display mode of the character design displayed on the second display screen is not changed. The player expresses the desired display mode change on the first display screen, and at the same time, the player's character on the first display screen is the target of his / her operation. The player can easily grasp it.

  Further, when the change condition calculation means calculates the change condition data using a plurality of definition areas (Z1 to Z4), it is possible to increase the interest of the game by increasing variations that change the display mode of the player character. . Further, in general, when the character design to be touched is divided into areas and the above variations are increased, it is considered that the area where the touch operation is performed becomes small and the operation desired by the player becomes difficult. Since the character design is displayed larger than the player character, the desired location of the player can be indicated relatively accurately even if the region is divided.

  Further, when the player character is a moving body that moves in the game space, and the change condition calculation means calculates the initial movement condition data and the movement change condition data as the change condition data, a variation that changes the display mode of the player character is provided. Increase the interest of the game.

  When the change condition calculation means calculates the change condition data according to the position coordinates at the input start time and the input end time, the player's intuitive operation is reflected in the change in the display mode of the player character on the first display screen. be able to.

  In addition, when calculating movement transition condition data according to the definition area that includes the position coordinates at the input start time or the input end time, it depends on the relationship between the coordinate position at the input start time or the end time and the character symbol definition area. Therefore, the player's intuitive operation can be reflected in the movement of the player character on the first display screen.

  In addition, when a plurality of definition areas are divided according to the direction from the input start time to the position coordinates from the input end time, it is possible to expect a change in the display mode of the player character based on the direction in which the player character is initially moved. Therefore, the player character can be intuitively predicted from the touch operation.

  In addition, when calculating the movement transition condition data so that the amount of change in the moving direction of the moving body increases according to the distance between the predetermined reference position and the straight line including the position coordinates at the input start time and the input end time, The variation which changes the display mode of a player character can be increased, and the interest property of a game can be increased. In addition, the player can intuitively understand that the amount of change increases.

  Further, when further functioning as a time measuring means, since the time during which the input is continued is reflected in the manner of changing the display mode, the intuitive operation is reflected by the change of the player character on the first display screen. be able to.

  Further, when a graphic showing the relationship between the position coordinates being input and the position coordinates at the start of input is displayed on the second display screen, the current input status to the touch panel can be shown to the player as needed.

  Further, in the case where the figure is represented by an isosceles triangle having the position coordinates during input as the vertex and the position coordinates at the start of input as the midpoint of the base of a predetermined length, the direction from the start point of the touch operation to the position during input and Distance can be shown simultaneously.

  According to the game device of the present invention, the same effect as the above-described game program can be obtained.

(First embodiment)

Further, a game cartridge 17 (hereinafter simply referred to as cartridge 17), which is a storage medium storing the game program of the present invention, is detachably mounted on the game apparatus 1. When the position detection accuracy of the touch panel 13 is high, it is effective to use the stylus 16. However, when the position detection accuracy is low, it is not necessary to use the stylus 16. It is also possible to input. Further, the touch panel 13 may be of any type such as a resistive film type, an optical type, an ultrasonic type, a capacitance type, and an electromagnetic induction type, and is particularly advantageous because the resistive film type is low cost. The detection method may be either a matrix method (digital) or a resistance value detection method (analog) depending on the configuration.

  FIG. 2 is a block diagram showing the configuration of the game apparatus 1. As shown in FIG. 2, the game apparatus 1 includes a CPU 21 that is an example of a computer for executing a game program. The CPU (central processing unit) 21 is electrically connected to a WRAM (working storage unit) 22, a first GPU (image processing unit) 23, a second GPU 24, and an I / F (interface) circuit 25 via a predetermined bus. Connected. The WRAM 22 is a memory that temporarily stores a game program executed by the CPU 21 and a calculation result of the CPU 21. The first GPU 23 draws a first game image to be displayed and output on the first LCD 11 in accordance with an instruction from the CPU 21 in a first VRAM (video RAM) 27, and the drawn first game image is displayed on the first display screen of the first LCD 11. 11a is displayed. The second GPU 24 draws a second game image (design) for display on the second LCD 12 in accordance with an instruction from the CPU 21 in the second VRAM 28, and displays the drawn second game image on the second display screen 12a. The I / F circuit 25 is a circuit that exchanges data between the CPU 21 and an external input / output device such as the touch panel 13, the operation key 14, and the speaker 15.

  The touch panel 13 (including the device driver for the touch panel) has a coordinate system corresponding to the coordinate system of the second VRAM 28, and the position coordinate data corresponding to the position input (instructed) by the stylus 16, the player's finger, or the like. Output. In this embodiment, the resolution of the display screen is 192 dots × 256 dots and the detection accuracy of the touch panel 13 will be described as 192 dots × 256 dots corresponding to the display screen, but the detection accuracy of the touch panel 13 is lower than the resolution of the display screen. It may be a thing.

  Further, a connector 26 is electrically connected to the CPU 21, and the cartridge 17 is detachably connected to the connector 26. The cartridge 17 is a storage medium for storing a game program. Specifically, the cartridge 17 includes a ROM 17a for storing the game program and a RAM 17b for storing backup data in a rewritable manner. The game program stored in the ROM 17a of the cartridge 17 is loaded into the WRAM 22, and the game program loaded into the WRAM 22 is executed by the CPU 21.

  Hereinafter, a game executed based on the game program will be described. In the first embodiment, the player character P1 displayed on the first display screen 11a is moved in accordance with a change in input given to the character symbol P2 on the second display screen 12a. Before explaining the detailed flow of the game program, the outline thereof will be described with reference to FIGS. 3 and 4 in order to facilitate understanding of the present invention. FIG. 3 is an example of one screen of the first game image and the second game image displayed on the first display screen 11a and the second display screen 12a by the game program, respectively. FIG. 4 is an example of a screen when the first game image on the first display screen 11a changes when an input change is given to the second display screen 12a.

  As shown in FIG. 3, the first game image is displayed on the first display screen 11a of the game apparatus 1, and the second game image showing the symbol associated with the first game image is displayed on the second display screen 12a. Is displayed. The first game image shows a state of the game space viewed from a predetermined viewpoint. Further, the symbol shown in the second game image is an image of a symbol corresponding to the type of game such as a character or item appearing in the game space, and the symbol is linked to the image included in the first game image. Associated with the program.

  Specifically, the game program is for displaying a billiard game using two screens. On the first display screen 11a, a billiard table D on which a hand ball P1 and six target balls T are placed is viewed from above. Is viewed as a first game image. The hand ball P1 is an image showing a player character that can be operated by the player, and the target ball T is an image that moves on the billiard table D due to a collision of the hand ball P1 or the like. On the other hand, in the second game image on the second display screen 12a, an image of the operation hand ball P2 that is enlarged and viewed from the top of the hand ball P1 is displayed as the character design of the present invention. The hand ball P1 and the operation hand ball P2 are associated by the game program, and a change in input given to the operation hand ball P2 using the touch panel 13 is an example of a change in the first game image. Is reflected in the change of the display mode (movement in this embodiment). Since the second display screen 12a is covered with the touch panel 13, the operation hand ball is detected by detecting an input to the area of the touch panel 13 corresponding to the display area of the operation hand ball P2 displayed on the second display screen 12a. Changes in the input given to P2 can be detected. The state of the first game image and the second game image at this time is shown in FIG.

  As shown in FIG. 4, 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 operation hand ball P2 displayed on the second display screen 12a. In the game apparatus 1, by detecting this change in input, for example, continuous input in the first direction LO is grasped. When continuous input in the first direction LO is detected, for example, the launch direction and initial speed for the hand ball P1 on the first display screen 11a are calculated based on at least two parameters included in the change in the continuous input. This launch direction and initial speed correspond to the change condition data in the present invention. Based on the launch direction and the initial speed, the first game image in which the hand ball P1 moves on the billiard table D along the trajectory OR is generated by moving while calculating the moving direction and the moving amount of the hand ball P1. The first game image is displayed on the first display screen 11a. Thus, based on the change of the input with respect to the touch panel 13 which covers the 2nd display screen 12a, the 1st game image of the 1st display screen 11a is changed. In this screen example, the drag is performed in the linear first direction LO. However, the screen may be dragged in a curved line or an S shape. In this case, if the position coordinates in the middle from the start point to the end point are also used as parameters, the hand ball P1 can be controlled to move so as to pass, for example, an S-shaped trajectory. Of course, in this case, the hand ball P1 is moved while calculating the rotation direction and the rotation rate of the ball.

  Next, with reference to FIG. 5 and FIG. 6, the process performed by the said game program is demonstrated concretely. 5 is a flowchart showing processing executed by the game program, FIG. 6A is a diagram showing a concept of data stored in the first VRAM 27, and FIG. 6B is stored in the second VRAM 28. FIG. 6C is a diagram showing the concept of the coordinate system of the touch panel 13.

  First, when a power supply (not shown) of the game apparatus 1 is turned on, a boot program (not shown) is executed by the CPU 21, whereby a game program stored in the cartridge 17 is loaded into the WRAM 22. When the loaded game program is executed by the CPU 21, the steps shown in FIG. 5 (abbreviated as “S” in FIG. 5) are executed.

  First, the first GPU 23 is operated by a command from the CPU 21, various image data such as a billiard table included in the game program is read, and the first game image is drawn in the first VRAM 27 (step 21). Specifically, as shown in FIG. 6A, a billiard table D, a hand ball P1, and a plurality of target balls T are drawn in the drawing area of the first VRAM 27. Then, the first game image in the first VRAM 27 is displayed and output on the first LCD 11. Next, the second GPU 24 operates in accordance with an instruction from the CPU 21, the character image data included in the game program is read, and the symbol associated with the first game image is drawn in the second VRAM 28 as the second game image. (Step 22). Specifically, as shown in FIG. 6B, the character design (handball for operation) P2, which is the operation target design, is drawn in the drawing area of the second VRAM 28. Then, the second game image in the second VRAM 28 is displayed and output on the second LCD 12. By executing Step 21 and Step 22, it is possible to start playing the billiard game.

  Then, the CPU 21 starts detecting input to the touch panel 13 (step 23). As shown in FIG. 6C, the touch panel 13 has a coordinate system corresponding to the coordinate system of the second VRAM 28, and position coordinate data corresponding to a position input (instructed) by the stylus 16, a player's finger, or the like. Is output. That is, in step 23, the CPU 21 detects position coordinates output from the touch panel 13 (including a device driver that controls the touch panel 13).

  Next, the CPU 21 determines whether or not the input is for the character symbol P2 (step 24). Specifically, the CPU 21 detects the coordinate area P3 (see FIG. 6B) in which the character coordinates P2 (see FIG. 6B) is drawn as the position coordinates first detected from the touch panel 13 (position coordinates that become the starting point of the input change). 6 (c)). If the detected position coordinates are included in the coordinate area P3, the CPU 21 proceeds to the next step 25 as an input to the character symbol P2, and repeats step 23 if it is not included in the coordinate area P3.

  When there is an input to the character symbol P2 in step 24, the CPU 21 executes the following steps 25 to 30 in order to detect a change in the input to the touch panel 13. First, the CPU 21 starts counting by a time counter for measuring time continuously input (step 25). Next, the CPU 21 temporarily stores the position coordinate data detected at the above step 24 at the input start time in the WRAM 22 (step 26). The position coordinate data of the start point stored in step 26 is the position coordinate at the input start time in the present invention.

  Then, the CPU 21 detects the input coordinates from the touch panel 13 at regular time intervals (step 27), and repeats the process of step 27 until there is no input from the touch panel 13 (step 28). That is, in step 27 and step 28, while the touch operation on the touch panel 13 is continuously performed, the CPU 21 continues to detect a change in input in response to the touch operation. In the present embodiment, if data input from the touch panel 13 is interrupted even once, it is determined that continuous input has ended. For example, when data input from the touch panel 13 cannot be detected in several consecutive detections, It may be determined that continuous input has been completed for the first time.

  When there is no input from the touch panel 13 in step 28 (that is, when the touch operation on the touch panel 13 by the player is finished), the CPU 21 stores the position coordinate data at the time when the input is finished in the WRAM 22 (step 29). The position coordinate data of the end point stored in step 29 is the position coordinate of the input end point in the present invention.

  Next, the CPU 21 stops counting by the time counter when there is no continuous input, and stores continuous input time data indicating how long the continuous input has continued in the WRAM 22 (step 30). The continuous input time data stored in step 30 is the input detection time in the present invention.

  Note that at step 26 and step 29 described above, at least two parameters (position coordinates at the input start time and input end time) are extracted from the change in the input to the touch panel 13. Furthermore, in this embodiment, a case where a total of three parameters including the continuous input time data (input detection time) detected in step 30 is used will be described. As will be apparent from the description below, in this embodiment, the position coordinates of two points at the start point and the end point are extracted. For example, a part or all of the position coordinate data of the intermediate point from the start point to the end point is used. Also good. In this embodiment, the time from the start point to the end point is used as continuous input time data. However, time data at a midpoint from the start point to the end point may be used. By using the time data at the midpoint, the behavior of the hand ball P1 is changed by the change in the input in the first half from the start point to the end point, so that a more intuitive movement of the hand ball P1 according to the operation of the player can be displayed. The types and number of these necessary parameters are determined depending on what kind of action the player object (hand ball P1 in this embodiment) wants to perform on the first display screen 11a. In other words, in the case of performing a complex motion, the number of parameters required to determine the complex motion increases, but in the case of a simple motion such as a linear movement, calculation is performed using two parameters. be able to.

  Next, the CPU 21 calculates change condition data such as the initial speed and moving direction of the hand ball P1 in the first game image on the first display screen 11a based on the stored parameters (step 31). Specifically, the input start time at step 26, that is, the position coordinate data of the start point, the input end time at step 29, that is, the position coordinate data of the end point, and the continuous input time data from the start point to the end point at step 30. Based on the three parameters, the initial speed and moving direction of the hand ball P1 are calculated.

  For example, if the start point (x1, y1), the end point (x2, y2), and the continuous input time t1, the CPU 21 determines the difference Δx = x2−x1 and Δy between the end point (x2, y2) and the start point (x1, y1). The moving direction (Δx, Δy) is calculated by = y2−y1. That is, if the place where the hand ball P1 is disposed is the position coordinate (X, Y), the position coordinate (X, Y) moves in the direction of movement (Δx, Δy) (first direction LO: FIG. 4). The hand ball P1 is moved. Then, as the initial speed of the hand ball P1, the initial speed is calculated so that the initial speed becomes faster as the continuous input time t1 is shorter. For example, initial speed = initial setting initial speed / continuous input time t1. Further, when calculating the initial speed, the difference (Δx, Δy) is taken into account, and the larger the difference is, the faster the initial speed is, and vice versa.

  Note that it is also possible to calculate the initial speed and the moving direction based on only two parameters of the start point (x1, y1) or the end point (x2, y2) and the continuous input time t1. For example, the center of the character symbol P2 is set to the reference position (x0, y0), and the difference between the start point or the end point and the reference position (x0, y0) is set as the moving direction of the handball P1, and the initial time of the handball P1 is determined by the continuous input time t1. Determine the speed. Furthermore, it is also possible to calculate the initial speed and the moving direction based on only two parameters of the start point (x1, y1) and the end point (x2, y2). For example, the difference between the end point and the start point may be set as the movement direction, and the magnitude of the difference may be reflected in the initial speed. Thus, if at least two parameters are extracted from the change in input to the touch panel 13, the first game image on the first display screen 11a can be changed in accordance with the change in input. In addition to calculating the conditions for moving the hand ball P1, in addition to the initial speed and the moving direction, conditions such as acceleration, deceleration, moving distance, and moving speed may be calculated.

  Next, the CPU 21 sets conditions for moving the hand ball P <b> 1 based on change condition data such as the initial speed and the moving direction, which are the calculation results calculated from the parameters in step 31. Based on the above conditions, the CPU 21 calculates how the hand ball P1 rolls and moves along the trajectory OR (see FIG. 4) while performing calculations such as deceleration due to friction with the billiard table, collision with the wall, and reflection. It displays on the 1st display screen 11a (step 32). Then, the CPU 21 repeatedly executes the processes of steps 24 to 32 until the game ends (step 33).

  In the present embodiment, the hand ball P1 is linearly moved by a change in linear input to the touch panel 13. However, for example, input of touch operation on a linear line while drawing a small circle on the touch panel 13 is performed. By giving a change, the hand ball P1 is launched in the direction in which the entire line is drawn, and the condition for the hand ball P1 to rotate according to the drawing method and direction of the circle is calculated. It can also be changed.

  As described above, according to the first embodiment, the hand ball P1 on the first display screen 11a moves in accordance with a change in input given to the character design, that is, an input pattern in which the touch panel 13 is touched. It is possible to provide a game with a sense of operation that has never existed before. Further, since the character pattern (hand ball P2 for operation) corresponding to the player character (hand ball P1) displayed on the first display screen 11a is displayed on the second display screen 12a larger than the player character, A desired location can be indicated relatively accurately. Further, the player character whose display mode changes is displayed on the first display screen 11a, and the player's operation is performed on the character pattern displayed on the second display screen 12a, so that the player character is hidden by the player's touch operation. Such a situation can be prevented. Further, the display mode of the player character on the first display screen 11a is changed in accordance with a relatively accurate input position and input change with respect to the character design, and the display mode of the character design displayed on the second display screen 12a is not changed. Therefore, the player can express the change in the desired display mode on the first display screen 11a, and at the same time, it does not occur that the symbol to be operated by the player cannot be identified.

(Second Embodiment)
A game apparatus equipped with a computer that executes a game program according to a second embodiment of the present invention will be described. In this embodiment, the case where the display mode of the player character included in the game image is changed will be described. However, the overall display mode of the game image may be changed. Note that the game device according to the second embodiment is the same as the game device 1 used in the first embodiment described above, and therefore, the same components are denoted by the same reference numerals and detailed description thereof is omitted. .

  Hereinafter, a game executed based on the game program will be described. Also in the second embodiment, the player character P1 is displayed on the first display screen 11a and the character symbol P2 is displayed on the second display screen 12a, as in the first embodiment. And according to the change of the input given to the character design P2 of the 2nd display screen 12a, the player character P1 displayed on the 1st display screen 11a is moved. Before describing the detailed flow of the game program, an outline thereof will be described with reference to FIGS. FIG. 7 is an example of one screen of the first game image and the second game image displayed on the first display screen 11a and the second display screen 12a by the game program, respectively. FIG. 8 shows an example in which the character design P2 is divided into a plurality of definition areas Z1 to Z4. FIG. 9 to FIG. 13 are examples of one screen when the first game image on the first display screen 11a changes when an input change is given to the second display screen 12a.

  As shown in FIG. 7, as in the first embodiment, the first game image is displayed on the first display screen 11a of the game apparatus 1, and the graphic associated with the first game image is displayed on the second display screen 12a. A second game image showing is displayed. The first game image shows a state of the game space viewed from a predetermined viewpoint. Further, the symbol shown in the second game image is an image of a symbol corresponding to the type of game such as a character or item appearing in the game space, and the symbol is linked to the image included in the first game image. Associated with the program.

  Specifically, as in the first embodiment, a billiard game using two screens is displayed, and a billiard table on which a hand ball P1 and six target balls T are placed on the first display screen 11a. A state in which D is viewed from above is displayed as the first game image. The hand ball P1 is an image showing a player character that can be operated by the player, and the target ball T is an image that moves on the billiard table D due to a collision of the hand ball P1 or the like. On the other hand, in the second game image on the second display screen 12a, an image of the operation hand ball P2 that is enlarged and viewed from the top of the hand ball P1 is displayed as the character design of the present invention. The hand ball P1 and the operation hand ball P2 are associated by the game program, and a change in input given to the operation hand ball P2 using the touch panel 13 is an example of a change in the first game image. Is reflected in the change of the display mode (movement in this embodiment). Since the second display screen 12a is covered with the touch panel 13, the operation hand ball is detected by detecting an input to the area of the touch panel 13 corresponding to the display area of the operation hand ball P2 displayed on the second display screen 12a. Changes in the input given to P2 can be detected.

  As shown in FIG. 7, the player performs continuous input on the touch panel 13 covering the second display screen 12 a with the stylus 16 and instructs input on the operation hand ball P <b> 2. In the game apparatus 1, the direction of continuous input is grasped by detecting this change in continuous input. In the game program according to the second embodiment, in response to the continuous input change, a graphic Tr for showing the input change to the player is drawn on the second game image. Specifically, when there is continuous input on the touch panel 13 with the display area of the operation hand ball P2 as the starting point S, the figure Tr is drawn according to the positional relationship between the starting point S and the currently input point N. The The figure Tr is an isosceles triangle having the point N as a vertex and a certain base length, and the start point S is arranged at the midpoint of the base.

  When this continuous input is detected and the continuous input is completed, for example, the movement of the first display screen 11a with respect to the hand ball P1 based on at least two parameters (for example, the start point and the end point of the continuous input) included in the change of the continuous input The quantity (moving direction) and speed are calculated. Furthermore, in this embodiment, the Ryukyu mode is set based on the above parameters.

  Specifically, the Ryukyu mode is set based on the relationship between the positions of the start point S and end point E included in the change in the continuous input and the definition area obtained by dividing the display area of the operation hand ball P2. As shown in FIG. 8, the operation hand ball P2 is defined by dividing the display area into, for example, four definition areas Z1 to Z4. The positions of these definition areas Z1 to Z4 change according to the direction from the start point S to the end point E (hereinafter referred to as the input direction). FIG. 8 shows the definition areas Z1 to Z4 when the input direction is set to the upward direction in the drawing.

  As shown in FIG. 8, let M be a straight line that is perpendicular to the input direction and passes through the center of the operation hand ball P2. Of the two points that are 22.5 ° forward and leftward (total 45 °) in the input direction at the outer edge of the operation hand ball P2, the right side is the point F1 and the left side is the point F2. Regarding the two points that are 22.5 ° rearward left and right (total 45 °) in the input direction at the outer edge of the operation hand ball P2, the right side is the point R1 and the left side is the point R2. In other words, the angle from point F1 to point R1 is 135 °, and the angle from point F2 to point R2 is also 135 °. A straight line connecting the points F1 and R1 is F1-R1, and a straight line connecting the points F2 and R2 is F2-R2. Here, the straight line F1-R1 and the straight line F2-R2 are both parallel to the input direction, and the display area of the operation hand ball P2 is divided into three by the straight line F1-R1 and the straight line F2-R2. The area on the right side of the straight line F1-R1 (the rightmost area divided into three) is the definition area Z3. Further, the left area (the leftmost area divided into three) of the straight line F2-R2 is the definition area Z4. Further, a region sandwiched between the straight line F1-R1 and the straight line F2-R2 (a central region divided into three) is defined regions Z1 and Z2. The region sandwiched between the straight line F1-R1 and the straight line F2-R2 is further divided vertically by a straight line M, and the upper region becomes the definition region Z1 and the lower region becomes the definition region Z2. Thus, since the definition areas Z1 to Z4 are set based on the input direction, the direction of the definition areas Z1 to Z4 changes when the input direction changes. Specifically, the definition areas Z1 to Z4 rotate around the center of the operation hand ball P2 as the input direction changes.

  Note that these definition areas Z1 to Z4 may be displayed separately on the second game image, or may not be displayed. As will be described later, the operation hand ball P2 is divided into the definition regions Z1 to Z4 so that a change in the display mode of the hand ball P1 (Ryukyu mode) can be predicted based on the direction in which the hand ball P1 is moved. Even if Z1 to Z4 are not divided and displayed as game images, the player can intuitively predict. In the above description, for the sake of simplicity, the operation hand ball P2 displayed in the second game image is divided to show the definition areas Z1 to Z4. However, in the actual processing, the operation hand ball P2 is The drawn coordinate area P3 (see FIG. 6C) may be divided into definition areas Z1 to Z4.

  In the Ryukyu mode, a plurality of types are set as variations that change the movement of the hand ball depending on the portion of the hand that is thrown by the cue. Specifically, the center of the handball P1 is cueed with a cue based on the direction in which the handball P1 is thrown, the “drawing ball” that whirls the lower part of the handball P1, the “push ball” that whirls the upper part of the handball P1, and the handball P1. The “left curve” for rolling the right part of the hand and the “right curve” for rolling the left part of the hand ball P1 can be set. When the starting point S included in the change in the continuous input is located in the definition area Z3, the Ryukyu mode is set to “left curve”. When the starting point S included in the change in the continuous input is located in the definition area Z4, the Ryukyu mode is set to “right curve”. When the starting point S included in the change in the continuous input is located in the definition area Z1, the Ryukyu mode is set to “push ball”. When both the start point S and the end point E included in the change in the continuous input are located in the definition area Z2, the Ryukyu mode is set to “pull ball”. When the start point S included in the change in the continuous input is located in the definition area Z2 and the end point E is located in the definition area Z1 or outside the display area of the operation hand ball P2, the Ryukyu mode is “centered”. Set to

  These movement amount (movement direction), speed, and Ryukyu mode correspond to the change condition data in the embodiment. Based on the change condition data, the first game image in which the hand ball P1 moves on the billiard table D is generated by moving while calculating the moving direction, moving amount, rotation direction, and rotation rate of the hand ball P1. Then, the first game image is displayed on the first display screen 11a.

  9 to 13 show first game image examples in which the hand ball P1 moves on the billiard table D according to each Ryukyu mode. 9 to 13 all show examples in which the input direction (indicated by the arrow S → E) is set from the left to the right of the drawing.

  In FIG. 9, the start point S of continuous input is located in the definition area Z2 of the operation hand ball P2, and the end point E is located in the definition area Z1. When this continuous input is detected, based on at least two parameters indicating the positions of the start point S and the end point E included in the change in the continuous input, the movement amount (movement direction) of the first display screen 11a with respect to the hand ball P1, Speed and Ryukyu mode are calculated. In this case, the Ryukyu mode is set to “centering”. Then, the first game image in which the hand ball P1 moves on the billiard table D along the trajectory g is generated by moving the hand ball P1 while calculating the movement amount and speed of the hand ball P1 based on the Ryukyu mode “center throw”. Then, the first game image is displayed on the first display screen 11a. As shown in FIG. 9, in the Ryukyu mode “centering”, the trajectory g is a straight line in the same direction as the input direction until contact with another object, and the rotation of the hand ball P <b> 1 is not set.

  In FIG. 10, the continuous input start point S is located within the definition area Z3 of the operation hand ball P2, and the end point E is located outside the display area of the operation hand ball P2. In this case, the Ryukyu mode is set to “left curve”, and the movement amount and speed with respect to the hand ball P1 are calculated based on at least two parameters indicating the positions of the start point S and the end point E. Based on the Ryukyu mode “left curve”, the hand ball P1 moves on the billiard table D along the trajectory g by moving while calculating the movement amount, speed, rotation direction, and rotation rate of the hand ball P1. The first game image to be generated is generated, and the first game image is displayed on the first display screen 11a. As shown in FIG. 10, in the Ryukyu mode “left curve”, the rotation of the hand ball P1 is set to the left rotation, and the trajectory g gradually turns to the left with respect to the input direction until it comes into contact with another object. Become.

  In FIG. 11, the start point S of continuous input is located within the definition area Z4 of the operation hand ball P2, and the end point E is located outside the display area of the operation hand ball P2. In this case, the Ryukyu mode is set to “right curve”, and the movement amount and speed with respect to the hand ball P1 are calculated based on at least two parameters indicating the positions of the start point S and the end point E. Based on the Ryukyu mode “right curve”, the handball P1 moves on the billiard table D along the trajectory g by moving while calculating the movement amount, speed, rotation direction, and rotation rate of the handball P1. The first game image to be generated is generated, and the first game image is displayed on the first display screen 11a. As shown in FIG. 11, in the case of the Ryukyu mode “right curve”, the rotation of the hand ball P1 is set to the right rotation, and the trajectory g gradually curves to the right with respect to the input direction until it comes into contact with another object. Become.

  In FIG. 12, both the start point S and the end point E of continuous input are located in the definition area Z2 of the operation hand ball P2. In this case, the Ryukyu mode is set to “pull ball”, and the movement amount and speed with respect to the hand ball P1 are calculated based on at least two parameters indicating the positions of the start point S and the end point E. Then, the handball P1 moves on the billiard table D along the trajectory g by moving while calculating the movement amount, speed, rotation direction, rotation rate, and the like of the handball P1 based on the Ryukyu mode “drawing ball”. A first game image to be generated is generated, and the first game image is displayed on the first display screen 11a. As shown in FIG. 12, in the Ryukyu mode “drawing ball”, the hand ball P1 is set to reverse rotation, and the trajectory g is a straight line in the same direction as the input direction until it comes into contact with another object. It is set to leave the target sphere T after contact.

  In FIG. 13, the starting point S of continuous input is located within the definition area Z1 of the operation hand ball P2, and the end point E is located outside the display area of the operation hand ball P2. In this case, the Ryukyu mode is set to “push ball”, and the movement amount and speed with respect to the hand ball P1 are calculated based on at least two parameters indicating the positions of the start point S and the end point E. Based on the Ryukyu mode “push ball”, the hand ball P1 moves on the billiard table D along the trajectory g by moving while calculating the movement amount, speed, rotation direction, and rotation rate of the hand ball P1. The first game image to be generated is generated, and the first game image is displayed on the first display screen 11a. As shown in FIG. 13, in the Ryukyu mode “push ball”, the hand ball P1 is set to forward rotation, and the trajectory g is a straight line in the same direction as the input direction until it comes into contact with another object. After the contact, the separation angle from the target sphere T is set to be small (for example, to follow the target sphere T in contact). Thus, based on the change of the input with respect to the touch panel 13 which covers the 2nd display screen 12a, the 1st game image of the 1st display screen 11a is changed.

  Next, processing executed by the game program will be specifically described with reference to FIGS. FIG. 14 is a flowchart showing processing executed by the game program. FIG. 15 is a subroutine showing detailed processing of the touch panel input processing in step 57 of FIG. FIG. 16 is a subroutine showing detailed processing of the change condition data calculation processing in step 61 of FIG. FIG. 17 is a subroutine showing detailed processing of the Ryukyu mode detection processing in step 84 of FIG. FIG. 18 is a subroutine showing detailed processing of the handball display position update processing in step 62 of FIG. FIG. 19 is a subroutine showing detailed processing of the handball contact processing in step 123 of FIG. FIG. 20 is a subroutine showing detailed processing of the gStepX and gStepY update processing in step 134 of FIG. FIG. 21 is a diagram for explaining a method of generating an isosceles triangle Tr displayed in step 74 of FIG. Note that the concepts of the first VRAM 27, the second VRAM 28, and the touch panel 13 in the processing executed by the game program are the same as those in FIG. 6 described in the first embodiment, for example.

  The processing when the game apparatus 1 is turned on in the present embodiment is the same as that in the first embodiment. 14 are the same as the processes of Step 21 to Step 26 described with reference to FIG. 5 in the first embodiment, and detailed description thereof is omitted.

  In step 57, the CPU 21 performs input processing from the touch panel 13 at regular time intervals. And CPU21 repeats the process of step 57 until there is no input from the touch panel 13 (step 58). That is, in step 57 and step 58, while the touch operation on the touch panel 13 is continuously performed, the CPU 21 continues the input process in response to the touch operation. In the present embodiment, if data input from the touch panel 13 is interrupted even once, it is determined that continuous input has ended. For example, when data input from the touch panel 13 cannot be detected in several consecutive detections, It may be determined that continuous input has been completed for the first time. Hereinafter, the details of the touch panel input process performed in step 57 will be described with reference to FIG.

  In FIG. 15, the CPU 21 determines whether or not it is the first input from the touch panel 13 (step 71). In the case of the first input, the CPU 21 displays a straight line having a length L on the left and right sides of the start point coordinates on the second game image (step 72), and ends the processing by the subroutine. As the start point coordinates, the position coordinate data at the input start time saved in step 56 is used. By the processing in step 72, a horizontal straight line having a length of 2L is drawn on the second display screen 12a with the start point touched by the player as the center.

  On the other hand, if it is determined in step 71 that it is the second time or later, the CPU 21 temporarily stores the position coordinates input from the touch panel 13 in the WRAM 22 as position coordinate data of the point N currently being input (step 73). Next, the CPU 21 displays an isosceles triangle Tr (see FIG. 7) having the point N as a vertex on the second game image (step 74), and ends the processing by the subroutine. The isosceles triangle Tr has a base of length 2L, and is drawn so that the midpoint of the base becomes the start point stored in step 56 above. Hereinafter, a method for generating an isosceles triangle Tr performed by the CPU 21 will be described with reference to FIG.

となる。また、二等辺三角形Ｔｒの底辺両端の２点をそれぞれＳ１およびＳ２とすると、点Ｓ１およびＳ２は、直線Ｎ１−Ｎ２上にある。したがって、それぞれの座標Ｓ１（Ｓ１ｘ、Ｓ１ｙ）およびＳ２（Ｓ２ｘ、Ｓ２ｙ）は、
Ｓ１ｘ＝（Ｌ／Ｑ）×Ｎ１ｘ＋Ｓｘ
Ｓ１ｙ＝（Ｌ／Ｑ）×Ｎ１ｙ＋Ｓｙ
Ｓ２ｘ＝（Ｌ／Ｑ）×Ｎ２ｘ＋Ｓｘ
Ｓ２ｙ＝（Ｌ／Ｑ）×Ｎ２ｙ＋Ｓｙ
となる。これらの点Ｎ、Ｓ１、およびＳ２を互いに直線で結べば、底辺長さ２Ｌで点Ｎを頂点とし、始点Ｓを当該底辺の中点とする二等辺三角形Ｔｒを描くことができる。 In FIG. 21, the starting point is a point S. Then, it is assumed that the point N is arranged at the coordinates N (Nx, Ny) and the point S is arranged at the coordinates S (Sx, Sy) with respect to the xy plane. Points N1 and N2 are points obtained by rotating the point N (Nx, Ny) by 90 ° and −90 ° with the point S (Sx, Sy) as the origin. In this case, the respective coordinates N1 (N1x, N1y) and N2 (N2x, N2y) are
N1x = cos (90 °) × (Nx−Sx) −sin (90 °) × (Ny−Sy)
N1y = sin (90 °) × (Nx−Sx) + cos (90 °) × (Ny−Sy)
N2x = cos (−90 °) × (Nx−Sx) −sin (−90 °) × (Ny−Sy)
N2y = sin (−90 °) × (Nx−Sx) + cos (−90 °) × (Ny−Sy)
Is calculated by And the length Q of the straight line connecting the point S and the point N is

It becomes. Further, assuming that two points at both ends of the base of the isosceles triangle Tr are S1 and S2, the points S1 and S2 are on the straight line N1-N2. Therefore, the respective coordinates S1 (S1x, S1y) and S2 (S2x, S2y) are
S1x = (L / Q) × N1x + Sx
S1y = (L / Q) × N1y + Sy
S2x = (L / Q) × N2x + Sx
S2y = (L / Q) × N2y + Sy
It becomes. By connecting these points N, S1, and S2 with a straight line, an isosceles triangle Tr having a base length of 2L and a point N as a vertex and a starting point S as a midpoint of the base can be drawn.

  In step 74, a figure other than an isosceles triangle may be drawn. For example, other figures may be drawn as long as the figure indicates the direction and distance from the start point S to the point N at the same time, such as a line connecting the start point S and the point N or an arrow from the start point S to the point N. .

  Returning to FIG. 14, when there is no input from the touch panel 13 in step 58 (that is, when the touch operation on the touch panel 13 by the player is finished), the process proceeds to step 59. 14 is the same as the process of step 29 and step 30 described with reference to FIG. 5 in the first embodiment, and detailed description thereof is omitted. It should be noted that at step 56 and step 59, at least two parameters (position coordinates at the input start time and input end time) are extracted from changes in the input to the touch panel 13. Furthermore, in this embodiment, a case where a total of three parameters including the continuous input time data (input detection time) detected in step 60 is used will be described. Also in the present embodiment, the types and number of these necessary parameters are determined depending on what kind of action the player object (the hand ball P1 in the present embodiment) on the first display screen 11a wants to perform.

  Next, the CPU 21 calculates change condition data such as the movement amount (movement direction), speed, and Ryukyu mode of the hand ball P1 in the first game image on the first display screen 11a based on the stored parameters (step). 61). Specifically, the input start time at step 56, that is, the position coordinate data of the start point, the input end time at step 59, that is, the position coordinate data of the end point, and continuous input time data from the start point to the end point at step 60. Based on the three parameters, the movement amount (movement direction) and speed of the hand ball P1 are calculated, and the Ryukyu mode is set. Hereinafter, the details of the change condition data calculation process will be described with reference to FIG.

  In FIG. 16, assuming that the start point S (x1, y1) and the end point E (x2, y2), the CPU 21 determines the difference Δx = x2−x1 and Δy between the end point E (x2, y2) and the start point S (x1, y1). = Y2-y1 is calculated (step 81). The CPU 21 obtains the continuous input time t1 in the above step 60. Next, the CPU 21 determines whether or not the continuous input time t1 = 0 or the differences Δx and Δy are both 0 (step 82). Then, when the continuous input time t1 = 0 or when the differences Δx and Δy are both 0, the CPU 21 turns off the movement flag (step 83) and ends the processing by the subroutine. On the other hand, if the continuous input time t1> 0 and at least one of the differences Δx and Δy is not 0, the CPU 21 advances the process to the next step 84.

  In step 84, the CPU 21 detects the Ryukyu mode using the position coordinate data of the start point S and the end point E. Hereinafter, the details of the Ryukyu mode detection process will be described with reference to FIG.

となる。ここで、Ａ＝（ｙ２−ｙ１）／（ｘ２−ｘ１）、Ｂ＝ｙ１−Ａ＊ｘ１である。そして、上記ｘ座標をそれぞれ直線ＳＥの式に代入すれば、２つの交点Ｑ１およびＱ２のｘｙ座標が求まる。なお、上記２つの交点のうち、終点Ｅ（ｘ２、ｙ２）に近い方を交点Ｑ２とする。 In FIG. 17, the CPU 21 calculates a straight line SE passing through the end point E and the start point S (step 101). Assuming that the start point S (x1, y1) and the end point E (x2, y2), the equation of the straight line SE passing through the end point E and the start point S is

It becomes. Next, the CPU 21 calculates two intersections Q1 and Q2 between the circle corresponding to the outer edge of the operation hand ball P2 and the straight line SE (step 102). The equation of the circle corresponding to the outer edge of the operating hand ball P2 is expressed as follows:
x ² + y ² = r ²
It becomes. And when solving the intersection of the straight line SE and the circle, its x coordinate is

It becomes. Here, A = (y2-y1) / (x2-x1) and B = y1-A * x1. Then, by substituting the x-coordinates into the equation of the straight line SE, the xy coordinates of the two intersections Q1 and Q2 can be obtained. Of the two intersections, the one closer to the end point E (x2, y2) is defined as an intersection point Q2.

  Next, the CPU 21 calculates angles of straight lines connecting the two intersections Q1 and Q2 and the center of the circle (step 103). The angle is obtained by substituting the xy coordinates of the two intersections obtained in step 102 for atan (y / x). When x = 0, the angle is set to 90 ° or 270 °. Further, when x1 = x2, in step 103, the respective angles are obtained by atan (y2 / x2) and atan (y1 / x1), and when x1 = 0 or x2 = 0, the angle is set to 90 ° or 270 °. To do.

  Next, the CPU 21 calculates the angle difference obtained in step 103 (step 104). Specifically, the angle corresponding to the intersection point Q1 is subtracted from the angle corresponding to the intersection point Q2. When the subtraction result is positive, the subtraction result is regarded as an angle difference. On the other hand, when the subtraction result is negative, 360 ° is added to the subtraction result to obtain an angle difference.

  Next, when the absolute value of the angle difference is 135 ° or less (Yes in step 105), the CPU 21 sets the Ryukyu mode to “left curve” and turns on the left curve flag (step 106). The processing by the subroutine is finished. If the absolute value of the angle difference is 225 ° or more (Yes in step 107), the CPU 21 sets the Ryukyu mode to “right curve” and turns on the right curve flag (step 108). Exit. In other words, the CPU 21 detects that the start point S of continuous input is located in the definition area Z3 of the operation hand ball P2 in step 105 (see FIG. 10). In step 107, the CPU 21 detects that the starting point S of continuous input is located in the definition area Z4 of the operation hand ball P2 (see FIG. 11).

  On the other hand, if the absolute value of the angle difference is greater than 135 ° and less than 225 ° (both Step 105 and Step 107 are No), the CPU 21 calculates a perpendicular line of the straight line SE passing through the center of the circle (Step 109). . Next, the CPU 21 calculates the positions of the start point S and the end point E based on the perpendicular obtained in step 109 (step 110). When both the start point S and the end point E are located on the definition area Z1 side (see FIG. 8) with respect to the perpendicular (Yes in step 111), the CPU 21 sets the Ryukyu mode to “push ball” and sets the push ball flag. Is turned on (step 112), and the processing by the subroutine is terminated. When the start point S and the end point E are both located on the definition area Z2 side with respect to the perpendicular (Yes in Step 113), the CPU 21 sets the Ryukyu mode to “drawing ball” and turns on the drawing ball flag ( Step 114), the processing by the subroutine is terminated. Further, when the start point S and the end point E are different from each other with respect to the perpendicular line (specifically, the start point S is located in the definition region Z2 and the end point E is located on the definition region Z1 side) (step 111). And Step 113 is No), the CPU 21 sets the Ryukyu mode to “centering”, turns on the centering flag (step 115), and ends the processing by the subroutine. In other words, the CPU 21 detects that the start point S of the continuous input is located in the definition area Z1 of the operation hand ball P2 by determining Yes in step 111 (see FIG. 13). Further, the CPU 21 determines that the result of step 113 is Yes, thereby detecting that the start point S and the end point E of the continuous input are both located in the definition area Z2 of the operation hand ball P2 (see FIG. 12). Yes. Furthermore, when the CPU 21 determines No in step 113, the start point S of the continuous input is located in the definition area Z2 of the operation hand ball P2, and the end point E is located in the definition area Z1 (FIG. 9). See).

Here, the formula of the perpendicular line of the straight line SE passing through the center of the circle calculated in step 109 is
y =-{(x2-x1) / (y2-y1)} x
Is required. Then, the CPU 21 can make the determinations in step 111 and step 113 based on the positive and negative values of the two numerical values C1 and C2 derived from the following equations.
C1 = y1 + {(x2-x1) / (y2-y1)} x1
C2 = y2 + {(x2-x1) / (y2-y1)} x2
In step 111, when both the numerical values C1 and C2 are positive, the CPU 21 determines that both the start point S and the end point E are located on the definition area Z1 side with respect to the perpendicular line. In step 113, if both the numerical values C1 and C2 are negative, the CPU 21 determines that both the start point S and the end point E are located on the definition area Z2 side with respect to the perpendicular.

  Returning to FIG. 16, after detecting the Ryukyu mode in step 84, the CPU 21 compares the absolute values of the differences Δx and Δy calculated in step 81 to determine whether or not | Δx |> | Δy |. (Step 85). If | Δx |> | Δy |, the CPU 21 calculates the movement amounts (movement directions) gStepX and gStepY per unit time based on the x-axis direction (step 86), and the process proceeds to the next step 88. Proceed to Specifically, in step 86, when the difference Δx is positive, the movement amount in the x-axis direction is set to gStepX = 1.0. Further, when the difference Δx is negative, the movement amount gStepX is set to −1.0. Also, the amount of movement in the y-axis direction is calculated as gStepY = Δy / | Δx |.

  On the other hand, if | Δx | ≦ | Δy |, the CPU 21 calculates the movement amounts (movement directions) gStepX and gStepY per unit time based on the y-axis direction (step 87), and the process proceeds to the next step 88. Proceed to Specifically, in step 87, if the difference Δy is positive, the movement amount in the y-axis direction is set to gStepY = 1.0. When the difference Δy is negative, the movement amount gStepY = −1.0 is set. Also, the amount of movement in the x-axis direction is calculated as gStepX = Δx / | Δy |.

で求められる。手球Ｐ１の速度は、連続入力時間ｔ１が短いほどその速度早くなるように算出されるが、ここでは連続入力時間ｔ１の影響を減らすように設定する。例えば、連続入力時間ｔ１を定数（例えば１６）で除算した後に平方根を取った数値ｔ１ａを用いる。そして、手球Ｐ１の速度ｇＳｐｅｅｄを
ｇＳｐｅｅｄ＝Ｌｓｅ／ｔ１ａ＋Ｓｐ１
で求める。ここで、Ｓｐ１は、最低速度定数（例えば１６）である。なお、計算された速度ｇＳｐｅｅｄが、予め設定された最高速度を超えていれば、速度ｇＳｐｅｅｄを当該最高速度に設定する。これによって、手球の速度ｇＳｐｅｅｄは、プレイヤのタッチ操作に応じて、初期値として最低速度〜最高速度の間で設定される。 In step 88, the CPU 21 sets the movement flag to ON. Next, the CPU 21 calculates the speed of the hand ball P1 based on the distance between the start point S and the end point E and the continuous input time t1 (step 89). The distance Lse between the start point S and the end point E is

Is required. The speed of the hand ball P1 is calculated so that the speed becomes faster as the continuous input time t1 is shorter. Here, the speed of the hand ball P1 is set to reduce the influence of the continuous input time t1. For example, a numerical value t1a obtained by dividing the continuous input time t1 by a constant (for example, 16) and then obtaining the square root is used. Then, the speed gSpeed of the hand ball P1 is gSpeed = Lse / t1a + Sp1
Ask for. Here, Sp1 is a minimum speed constant (for example, 16). If the calculated speed gSpeed exceeds a preset maximum speed, the speed gSpeed is set to the maximum speed. Thereby, the speed gSpeed of the hand ball is set between the minimum speed and the maximum speed as an initial value in accordance with the touch operation of the player.

  The movement amounts gStepX and gStepY calculated in step 86 or 87 and the speed gSpeed calculated in step 89 may be arbitrarily adjusted according to the operation of the hand ball P1 on the first display screen 11a. . For example, by multiplying the speed gSpeed by a constant (for example, 88) or by dividing the movement amounts gStepX and gStepY by a constant (for example, 16), the movement of the hand ball P1 expressed on the first display screen 11a is adjusted. Can do.

  Next, the CPU 21 determines whether one of the left curve flag and the right curve flag (hereinafter collectively referred to as a curve flag) is set to ON (step 90). Then, when the curve flag is OFF, the CPU 21 ends the process by the subroutine. On the other hand, when the curve flag is ON, the CPU 21 sets the curve coefficient k (step 91), and ends the processing by the subroutine. The curve coefficient k indicates an angle at which the absolute value is set to be larger as the distance between the straight line (straight line SE) connecting the start point S and the end point E and the center of the operation hand ball P2 increases. The angle at which the handball P1 is moved when the display position is moved is set to be about 2 ° to 7 °. Specifically, the curve coefficient k is set using the angle calculated in step 103. For example, when the angle is α, the curve coefficient k = (α−67) /24−4.5 is set when the Ryukyu mode is “left curve”. In the case of the “right curve”, the curve coefficient k = (α−292) /24+4.5 is set. According to this calculation formula, a negative curve coefficient k is set for the “left curve”, and a positive curve coefficient k is set for the “right curve”. Note that the equation for calculating the curve coefficient k can be arbitrarily adjusted according to the motion represented by the hand ball P1 on the first display screen 11a.

  Returning to FIG. 14, the CPU 21 updates the display position of the hand ball P <b> 1 based on the change condition data such as the movement amount and speed calculated in the change condition data calculation process in step 61, and the hand ball P <b> 1 rolls and moves. The state is displayed on the first display screen 11a (step 62). The details of the handball display position update process will be described below with reference to FIG.

  In FIG. 18, the CPU 21 determines whether or not the movement flag is ON (step 120). Then, the CPU 21 proceeds to the next step 121 when the movement flag is ON, and ends the processing according to the subroutine when the movement flag is OFF.

  In step 121, the CPU 21 sets a loop counter LC for counting the number of loops for determining the amount of movement and the direction of movement of the hand ball P1 per unit time according to the currently set speed gSpeed. Set to. For example, a value calculated by loop counter LC = gSpeed / 128 + 1 (rounded down after the decimal point) is set, and at least one value corresponding to the speed gSpeed is set. The set value of the loop counter LC can also be arbitrarily adjusted according to the operation represented by the hand ball P1 on the first display screen 11a.

  Next, the CPU 21 adds the movement amount gStepX currently set to the x coordinate value of the xy coordinates set as the display position of the hand ball P1, and adds the movement amount gStepY to the y coordinate value of the xy coordinates ( Step 122). Then, based on the display position (xy coordinates) of the hand ball P1 added in step 122, the CPU 21 performs a process in which the hand ball P1 comes into contact with another object (step 123). Hereinafter, the details of the handball contact process will be described with reference to FIG.

  In FIG. 19, the CPU 21 determines whether or not the hand ball P <b> 1 contacts the edge of the billiard table D based on the display position (xy coordinates) of the hand ball P <b> 1 added in step 122 (step 141). Next, when the hand ball P1 is in contact with the edge of the billiard table D, the CPU 21 determines whether or not the hand ball P1 is in contact with the edges installed at the top and bottom of the first display screen 11a (step 142). Then, when the hand ball P1 comes into contact with the edges (that is, the left and right edges) that are not the upper and lower sides of the billiard table D, the CPU 21 reverses the sign of the currently set movement amount gStepX and proceeds to the next step 145. Proceed. Further, when the hand ball P <b> 1 comes into contact with the upper and lower edges of the billiard table D, the CPU 21 reverses the sign of the currently set movement amount gStepY and advances the processing to the next step 145.

  In step 145, the CPU 21 decelerates the speed gSpeed of the hand ball P1 based on a predetermined deceleration rate set for contact with the edge. For example, the speed gSpeed is reduced by multiplying the currently set speed gSpeed by 7/8. Then, the CPU 21 advances the processing to the next step 149.

  When it is determined in step 141 that the hand ball P1 does not come into contact with the edge of the billiard table D, the CPU 21 determines whether or not the hand ball P1 is in a pocket provided on the billiard table D (step 146). When the hand ball P1 enters the pocket, the CPU 21 sets the speed gSpeed to 0 and performs pocket-in processing (step 147), then turns off the movement flag (step 148), and performs processing according to the subroutine. finish. On the other hand, if the hand ball P1 is not in the pocket, the CPU 21 advances the process to the next step 149.

  In step 149, based on the display position (xy coordinates) of the hand ball P1 added in step 122, it is determined whether or not the hand ball P1 is in contact with another target ball T. Then, when the hand ball P1 comes into contact with another target ball T, the CPU 21 advances the process to the next step 150. On the other hand, when the hand ball P1 does not come into contact with another target ball T, the CPU 21 ends the processing by the subroutine.

  In step 150, the CPU 21 detects a condition in which the hand ball P1 and the target ball T are in contact with each other. Here, the contact condition includes not only the moving direction and moving speed (movement vector) of each of the contacted hand ball P1 and the target ball T but also the angle at which the hand ball P1 and the target ball T have contacted, the contact point thereof, and the like. Next, the CPU 21 updates the movement amounts gStepX and gStepY set in the hand ball P1 based on the contact condition detected in step 150 (step 151). For example, the movement amounts gStepX and gStepY are updated using the result obtained by adding the movement vectors of the hand ball P1 and the target ball T. Further, the signs of the movement amounts gStepX and gStepY are changed according to the positions of the hand ball P1 and the target ball T. As described above, the movement amounts gStepX and gStepY are updated according to the contact condition, but further description thereof is omitted here.

  Next, the CPU 21 updates the speed gSpeed set in the hand ball P1 based on the contact condition detected in step 150 (step 152). For example, in the update of the speed gSpeed, the speed gSpeed is set to 0 when the hand ball P1 and the target ball T collide head-on, and the deceleration amount of the speed gSpeed is reduced according to the shift amount of the spheres. In the present embodiment, when the hand ball P1 and the stopped target ball T come into contact with each other, the speed gSpeed of the hand ball P1 is reduced to at least 50%. In addition, when the moving speed of the target ball T is higher than the moving speed of the hand ball P1, the speed gSpeed of the hand ball P1 may be increased. As described above, the speed gSpeed is updated according to the contact condition, but further description is omitted here.

  Next, the CPU 21 calculates the amount of movement and the speed of the target ball T in contact with the hand ball P1 (step 153). The movement amount and speed are set for the target ball T as well as the hand ball P1 and updated according to the contact condition. However, further explanation is omitted here.

  Next, the CPU 21 determines whether or not the Ryukyu mode of the hand ball P1 is set to “push ball” or “draw ball” (step 154). Specifically, the CPU 21 makes a determination using the push ball flag turned on in step 112 or the draw ball flag turned on in step 114. When the Ryukyu mode of the hand ball P1 is set to “push ball” or “drawing ball”, the CPU 21 sets a curve coefficient k corresponding to the Ryukyu mode (step 155), and ends the processing by the subroutine. To do. On the other hand, when the Ryukyu mode of the hand ball P1 is not set to either “push ball” or “draw ball”, the CPU 21 ends the processing by the subroutine as it is. Here, when the Ryukyu mode is “push ball”, the curve coefficient k set in step 155 has a smaller separation angle from the target ball T in the movement of the display position of the hand ball P1, which will be described later (for example, the target ball touched). To follow T). Further, the curve coefficient k is set such that when the Ryukyu mode is “pull ball”, the separation angle from the target ball T is increased (for example, away from the target ball T in contact) when the display position of the hand ball P1 is moved. The In this embodiment, when the Ryukyu mode is “push ball”, the curve coefficient k is set to + 3 °, and when the Ryukyu mode is “pull ball”, the curve coefficient k is set to −3 °. Note that the set value of the curve coefficient k may not be the above-described fixed value. The curve coefficient k can be arbitrarily adjusted according to the motion represented by the hand ball P1 on the first display screen 11a. For example, the set value may be changed according to the contact condition.

  Returning to FIG. 18, after the handball contact process in step 123, the CPU 21 determines whether or not the handball P <b> 1 has contacted another object based on the display position (xy coordinates) of the handball P <b> 1 added in step 122. (Step 124). The contact between the hand ball P1 and the other object can be determined from the processing result of step 123. When the hand ball P1 and the other object are not in contact (all the above-mentioned steps 141, 146, and 149 are No), the CPU 21 Decreases the set value of the loop counter LC by -1 (step 125). Then, the CPU 21 determines whether or not the set value of the loop counter LC is 0 (step 126). If the set value of the loop counter LC is not 0, the CPU 21 returns to step 122 and repeats the process.

  On the other hand, when the set value of the loop counter LC becomes 0, the CPU 21 designates the xy coordinates currently set as the display position of the hand ball P1 as the display position of the hand ball P1 in the first game image, and uses the hand ball P1. The information is displayed on the first display screen 11a (step 127), and the process proceeds to the next step 128. This step 127 is a step in which the CPU 21 repeats the process every unit time, and the display position of the hand ball P1 in the first game image is also updated every unit time. Here, the display position of the hand ball P1 is updated by adding the movement amounts gStepX and gStepY in step 122 and repeating the addition by the number of set values of the loop counter LC. That is, the hand ball P1 moves to the display position where the movement amounts gStepX and gStepY are repeatedly added by the number set by the loop counter LC, and is displayed on the first game image. Further, since the set value of the loop counter LC is set according to the speed gSpeed, the hand ball P1 moves according to the movement amounts gStepX and gStepY and the speed gSpeed per unit time and is displayed on the first game image. It will be.

  If it is determined in step 124 that the hand ball P1 has come into contact with another object (any of the above steps 141, 146, and 149 is Yes), the CPU 21 determines the xy coordinates currently set as the display position of the hand ball P1. The display is designated as the display position of the hand ball P1 in one game image, the hand ball P1 is displayed on the first display screen 11a (step 136), and the process returns to step 120 and is repeated. Note that the processing in step 136 is the same as that in step 127, and a detailed description thereof will be omitted.

  After displaying the hand ball P1 on the first game image in step 127, the CPU 21 determines whether the speed gSpeed is high (step 128) and whether the speed gSpeed is medium (step 129). To do. In these steps 128 and 129, the CPU 21 classifies the current speed gSpeed of the hand ball P1 into high speed, medium speed, and low speed. For example, gSpeed ≧ 512 is high speed, 512> gSpeed ≧ 256 is medium speed, 256> gSpeed Is defined as slow.

  When the speed gSpeed is high (Yes in Step 128), the CPU 21 sets a new speed gSpeed by subtracting the current speed gSpeed based on the friction coefficient (Step 130), and proceeds to the next Step 133. . Specifically, in step 130, a value obtained by dividing the speed gSpeed by a predetermined friction constant (for example, 28) is subtracted from the speed gSpeed. Further, when the speed gSpeed is medium speed (Yes in Step 129), the CPU 21 sets a new speed gSpeed by subtracting a constant b (for example, b = 16) from the current speed gSpeed (Step 131). To the next step 133. Further, when the speed gSpeed is low (both steps 128 and 129 are No), the CPU 21 sets a new speed gSpeed by subtracting a constant c (b> c; for example, c = 7) from the current speed gSpeed. (Step 132), and the process proceeds to the next step 133. The classification and deceleration value of the speed gSpeed may be arbitrarily adjusted according to the motion represented by the hand ball P1 on the first display screen 11a. For example, the classification of the speed gSpeed is further increased to correspond to each classification. You may set a different deceleration value.

  In step 133, the CPU 21 determines whether or not the speed gSpeed ≦ 0. When the speed gSpeed ≦ 0, the CPU 21 turns off the movement flag (step 135) and ends the processing by the subroutine. On the other hand, when the speed gSpeed> 0, the CPU 21 performs an update process of the movement amounts gStepX and gStepY (step 134), returns to step 120, and repeats the process. That is, the handball display position updating process is repeated until the speed gSpeed becomes 0 or less. The details of the movement amount gStepX and gStepY update processing will be described below with reference to FIG.

  In FIG. 20, the CPU 21 determines whether or not the center throwing flag is turned on as the throwing ball mode of the hand ball P1 (step 161), whether the push ball flag or the pulling ball flag is turned on (step 162), and the curve flag. Is determined (step 163). Then, when the center rolling flag is ON (Yes in step 161), the CPU 21 advances the process to the next step 166. Further, when the push ball flag or the draw ball flag is ON (Yes in Step 162), the CPU 21 determines whether or not the curve coefficient k corresponding to the ON flag is set (Step 164). If the curve coefficient k corresponding to the ON flag is not set (No in step 164), the CPU 21 proceeds to the next step 166, where the curve coefficient k is set (Yes in step 164). ), The process proceeds to the next step 165. Further, the CPU 21 proceeds to the next step 165 when the curve flag is turned on (Yes in step 163), and performs the process when none of the flags is turned on (all steps 161 to 163 are No). Proceed to next step 166.

  In step 165, the CPU 21 subtracts a predetermined amount from the absolute value of the curve coefficient k, and proceeds to the next step 166. For example, when the curve coefficient k is set in accordance with the turned curve flag, the CPU 21 subtracts 0.1 from the absolute value of the curve coefficient k. When the curve coefficient k is set according to the pushed ball flag or the pulled ball flag that is turned on, the CPU 21 subtracts 0.2 from the absolute value of the curve coefficient k. Note that the subtraction value of the curve coefficient k may be arbitrarily adjusted according to the motion represented by the hand ball P1 on the first display screen 11a.

In step 166, the CPU 21 updates the movement amounts gStepX and gStepY based on the curve coefficient k, and ends the processing by the subroutine. When the curve coefficient k is not set, the curve coefficient k = 0. Specifically, the CPU 21 updates the movement amounts gStepX and gStepY based on the following expressions.
gStepX = cosk * gStepX−sink * gStepY
gStepY = sink * gStepX + cosk * gStepY
Here, gStepX and gStepY on the left side indicate the updated movement amounts gStepX and gStepY, respectively. Further, gStepX and gStepY on the right side indicate the movement amounts gStepX and gStepY before updating, respectively. By this update, the movement amounts gStepX and gStepY after the update are values obtained by rotating the movement amounts gStepX and gStepY before the update by an angle k around the origin. As described above, since the movement amounts gStepX and gStepY are parameters for moving the hand ball P1 every unit time, the movement amounts gStepX and gStepY are updated in step 166 so that the hand ball P1 is curved at an angle k. It can be expressed by one game image.

  Returning to FIG. 14, after the handball display position update process in step 62, the CPU 21 determines whether or not to end the game (step 63). Then, the CPU 21 repeatedly executes the processing of step 54 to step 62 until the game ends.

  As described above, according to the second embodiment, in addition to the effects in the first embodiment described above, according to the input change given to the operation target symbol, that is, according to the input pattern for touch-operating the touch panel 13. Since the input situation is drawn as a figure (isosceles triangle Tr), the current input situation can be shown to the player at any time. In the second embodiment, the character design (hand ball P2 for operation) corresponding to the player character (hand ball P1) displayed on the first display screen 11a is divided into regions, and the display mode of the player character is further changed. Increasing variations to increase the interest of the game. On the other hand, in general, when the character design to be touched is divided into areas and the above variations are increased, it is conceivable that the area where the touch operation is performed becomes small and the operation desired by the player becomes difficult. However, according to the second embodiment, since the character design is displayed larger than the player character on the second display screen 12a, the desired location of the player is indicated relatively accurately even if the region is divided. be able to. Further, since the character design is divided into regions so that a change in the display mode of the player character can be predicted based on the direction in which the player character is moved, a change in the player character can be predicted intuitively from a touch operation. Further, since the player's touch operation only inputs the start point and the end point for the character symbol displayed on the second display screen 12a, it is possible to prevent the level of complexity / difficulty of the game operation from being excessively increased. Thus, various movements of the player object can be realized with simple operations.

  In the second embodiment described above, the Ryukyu mode is basically set based on the position of the starting point S (in order to distinguish the Ryukyu mode from “center throwing” and “drawing ball”, the end point E The position is considered; see FIGS. 9 to 13), and the Ryukyu mode may be set based on the position of the end point E. For example, when the end point E is located in the definition area Z3, the Ryukyu mode “left curve” is set, and when the end point E is located within the definition area Z4, the Ryukyu mode “right curve” is set. When it is located in the area Z2, the Ryukyu mode “drawing ball” is set, and when the end point E is located in the definition area Z1, the Ryukyu mode “center throwing” is set. If the Ryukyu mode is set to “push ball” when positioned inside, the Ryukyu mode based on the position of the end point E can be basically set.

  In the first and second embodiments described above, as shown in FIG. 1, the first game image is displayed on the first display screen 11 a of the first LCD 11, which is physically two display devices, and the second LCD 12. Although the game apparatus 1 that displays the second game image on the two-display screen 12a has been described, the present invention is not limited to the game program executed on such a game apparatus 1. For example, a game device having a single physical display device may be used by dividing the display screen of the display device into two. An example of a game device provided with this single display device is shown in FIG.
