Description

The present invention is a game apparatus may have an effect on the game progress with respect to the sighting directed to the screen by operating the controller, and relates to a game program for realizing the game apparatus.

  2. Description of the Related Art Conventionally, for example, a gun shooting game is known as a game in which an aim is made on a screen on which a game image is displayed by operating a controller and the game progresses. In a gun shooting game, a game image representing a virtual game space is generally displayed on the screen. When the player aims at a target such as an enemy character displayed on the screen using a gun controller simulating a gun and performs a trigger operation, the player character in the screen fires a bullet toward the target. If the bullet shot by the player character hits the enemy character, for example, the enemy character can be damaged or the enemy character can be defeated.

  In a gun shooting game, a configuration is disclosed in which one player can operate a plurality (two) of gun controllers (see, for example, Patent Document 1). If two gun controllers are used, there is an advantage in the progress of the game that it is possible to shoot with both hands and easily defeat the enemy.

  However, in the above-described conventional configuration, only two gun controllers can be operated, the game performance is relatively simple, and the game is not interesting.

  Hereinafter, as a preferred embodiment of the present invention, a case where the game apparatus according to the present invention is applied to a so-called arcade type gun shooting game apparatus will be specifically described with reference to the drawings.

  FIG. 1 is an overview of the game device according to the present embodiment. The game apparatus A includes two monitors 1 as display means, an LED 2, a gun controller 3, and a foot kick input device 4.

  The monitor 1 displays a game image and is composed of a relatively large liquid crystal panel. The two monitors 1 are arranged with their screens close to each other in the horizontal direction, and the entire game image is displayed across these two screens.

  The LED 2 is used for optically detecting the aiming position on the screen when the gun controller 3 is aimed at the screen of the monitor 1. In order to prevent erroneous detection, the LED 2 is an infrared LED, and at least two LEDs 2 are installed so as to emit infrared light from the vicinity of the screen of the monitor 1 to the front of the screen.

  The gun controller 3 is for the player to aim at a target, which will be described later, displayed on the screen, and to perform an operation as if shooting with a gun toward the aim. As shown in FIG. 2, the gun controller 3 includes a trigger 31 and a trigger switch 32. When the trigger 31 is operated by the player, a signal is output from the trigger switch 32 in conjunction with the operation. . The gun controller 3 also includes an image sensor 33 and an image processing unit 34. On the incident side of the image sensor 33, an infrared filter that passes only infrared light is provided together with an optical lens (not shown). The image sensor 33 and the image processing unit 34 are for specifying the aiming position of the gun controller 3 that is directed to the screen of the monitor 1. Although details will be described later, when the player sets the aim of the gun controller 3 on the screen of the monitor 1 and operates the trigger 31, the player character moves toward the aim in the virtual game space in conjunction with the trigger operation. Is displayed on the screen of the monitor 1. The gun controller 3 may be provided with operation buttons for performing other operations such as changing the type of weapon.

  In this embodiment, as shown in FIG. 1, four gun controllers 3 are provided. Two of these gun controllers 3 are arranged on the left and right sides of the stage 5. The game apparatus A can be played by one person or simultaneously by two persons. In the game apparatus A, for example, it is set so that one player can use the two gun controllers 3 when a predetermined condition is satisfied during the game.

  The foot kick input device 4 is for inputting by a kick operation using the player's foot (hereinafter referred to as “kick input” as appropriate), and is disposed below the monitor 1 (on the player side). As shown in FIG. 3, the foot kick input device 4 includes a kick pedal 41 for a player to perform a kick operation, and a pedal switch 42 for detecting the kick operation. The kick pedal 41 is configured such that a transparent panel 412 formed in a rectangular shape by, for example, acrylic resin is supported by a rectangular frame body 411. The transparent panel 412 is a part that the player directly kicks with his / her foot, and is supported by the frame body 411 in an inclined posture so as to move away from the monitor 1 as it goes downward. The frame body 411 has a step portion 411 a that restricts the movement of the transparent panel 412 toward the back side (monitor 1 side). Further, stoppers 413 for restricting the movement of the transparent panel 412 to the front side are attached to the four corners of the frame body 411. The distance between the stepped portion 411 a and the stopper 413 is slightly larger than the thickness of the transparent panel 412. As a result, the transparent panel 412 can be displaced from the near side to the far side while maintaining an inclined posture between the step portion 411a and the stopper 413. Between the step part 411a and the transparent panel 412, for example, an elastic member (not shown) configured by a spring is interposed. By appropriately providing the elastic member at a plurality of locations, the transparent panel 412 is always urged to the near side where the player should stand. Thereby, it has a moderate click feeling (input feeling) with respect to the kicking operation to the kick pedal 41. Note that the kick pedal 41 has a strength capable of withstanding an impact load when the player is strongly kicked by the player.

  The pedal switch 42 is provided in the step portion 411 a of the frame body 411 and is located between the step portion 411 a and the transparent panel 412. The pedal switch 42 is configured by, for example, a piezoelectric element and a load sensor (pressure sensor) including a circuit that detects a load applied to the piezoelectric element as a resistance change. The pedal switch 42 can detect a kick input when a kick operation (kick input) is performed on the transparent panel 412 with a predetermined load or more against the urging force of the elastic member, and the transparent panel 412 is displaced to the back side. Is possible. In the present embodiment, four pedal switches 42 are provided, and these pedal switches 42 are arranged substantially evenly so as to correspond to the four sides of the transparent panel 412. Although details will be described later, when an input is detected by any of the pedal switches 42, a pedal operation signal is output from the pedal switch 42. Further, the kick input device 4 can detect a kick input when a predetermined condition is satisfied in the progress of the game. In other words, even if the player makes a kick input when a predetermined condition is not satisfied in the progress of the game, the kick input is not detected.

  As shown in FIG. 1, a light emitting panel 43 is provided behind the kick pedal 41. The light emitting panel 43 includes, for example, LEDs, and is configured to be able to light a plurality of different colors (for example, blue and red) for each color according to predetermined conditions. When the light emitting panel 43 is turned on, the player can visually recognize the lighting state of the light emitting panel 43 through the transparent panel 412.

In the present embodiment, as shown in FIG. 1, two foot kick input devices 4 are provided side by side. When two players play simultaneously, each player can use the foot kick input device 4.

  FIG. 4 is a block diagram showing an internal electrical configuration of the game apparatus A. As shown in FIG. The game apparatus A includes a CPU 101, a ROM 102, a RAM 103, a GPU 104, a VRAM 105, a video interface 106, an input interface 107, and an output interface 108 as hardware. The CPU 101, ROM 102, RAM 103, GPU 104, input interface 107, and output interface 108 are connected to each other via a bus 109. Two monitors 1 are connected to the GPU 104 via a VRAM 105 and a video interface 106. The input interface 107 is connected to the trigger switch 32, the image processing unit 34, and the pedal switch 42. The output interface 108 is connected to the aiming position detection LED 2 and the light emitting panel 43. Note that the speaker 6 is connected to the bus 109 via an output interface 108 (audio interface) (see FIG. 1). The output interface 108 is connected to a stage swinging device and a light emitter of an illumination unit (not shown). ) Is connected. The trigger switch 32, the image sensor 33, and the image processing unit 34 are provided in all the gun controllers 3. However, only one gun controller 3 is illustrated, and the remaining gun controllers 3 are not illustrated.

  The CPU 101 executes system programs and game programs stored in the ROM 102, and performs various input / output controls and arithmetic processes. For example, the CPU 101 sends a command to the GPU 104 to display a predetermined game image on the monitor 1 in accordance with various signals and information input from the gun controller 3 or the pedal switch 42 via the input interface 107. Further, the CPU 101 operates the stage swinging device (not shown) and the light emitting panel 43 according to predetermined conditions defined in the game program. Further, the CPU 101 causes the speaker 6 to output a predetermined audio signal based on the audio data when executing the game program.

  The ROM 102 is a read-only semiconductor memory. The ROM 102 stores a system program for controlling basic operations of the hardware and a game program in which instructions for causing the CPU 101 to execute various processes relating to the game are stored. The ROM 102 stores game CG data and audio data, and a control table. Further, the ROM 102 also stores layer data for combining an aiming mark (to be described later) with a game image for display (overlay display). The aiming mark is an object for indicating the aiming position of the gun controller 3 on the game image. The aiming mark includes a normal aiming mark and a special aiming mark, which will be described in detail later.

  The CG data includes polygon data and texture data for generating a virtual game space. Polygon data and texture data are data for representing a target enemy character or a dynamic character such as a player character as if viewed by a player, and a static object such as a background, an object, or a gun by a three-dimensional shape model. . The virtual game space is generated by arranging a three-dimensional shape model in a predetermined three-dimensional coordinate system. In the virtual game space, a virtual camera that images the virtual game space in two dimensions is arranged. A two-dimensional image captured by the virtual camera is displayed on the monitor 1. The virtual camera is placed on the player character, for example. In this case, the player can view the virtual game space from the viewpoint of the player character (first person viewpoint: first person shooting game). In the control table, for example, various parameters such as a physical strength value and an attack power of the enemy character and the player character during the game progress are defined.

  The game program includes a program for generating a virtual game space, and also includes a program for changing the physical strength value and attack power of the enemy character and player character in accordance with the game progress status. For example, by executing a game program, the CPU 101 determines a virtual game space in which the player character should advance for each predetermined game stage, and determines the player character's physical strength value or the like according to various events occurring in the virtual game space. Increase or decrease attack power. Note that the game CG data, audio data, and game program may be recorded on a recording medium such as a hard disk, an optical disk, or a flash memory, and may be appropriately read from the recording medium via a reading device.

  The RAM 103 is a readable / writable semiconductor memory, and is used for loading a program by the CPU 101 and temporarily storing data and the like. For example, the RAM 103 stores CG data read from the ROM 102, and then the CG data is called from the RAM 103 and transferred to the GPU 104.

  The GPU 104 performs high-speed calculation processing necessary for image display processing, such as generating a three-dimensional virtual game space and generating a two-dimensional image from the virtual game space. Specifically, first, the GPU 104 generates a three-dimensional shape model of an enemy character and a background by executing a modeling process based on polygon data in accordance with a command from the CPU 101. Next, the GPU 104 gives a texture to the surface of the three-dimensional shape model by executing a texture mapping process based on the texture data. Next, the GPU 104 executes a layout setting process to place a three-dimensional shape model at a predetermined position in the three-dimensional coordinate system and generate a virtual game space in which enemy characters and backgrounds exist. At this time, virtual cameras and light sources are also arranged at predetermined positions in the three-dimensional coordinate system. Finally, the GPU 104 executes a rendering process for calculating the relative position and shading of the three-dimensional shape model with respect to the virtual camera, thereby obtaining a two-dimensional image obtained by imaging the virtual game space with the camera. Is generated. The two-dimensional image generated by the GPU 104 is sequentially transferred to the VRAM 105. Further, the GPU 104 performs a process of combining the aim mark with the two-dimensional image according to a command from the CPU 101, and transfers the two-dimensional image including the aim mark to the VRAM 105.

  The VRAM 105 is a semiconductor memory dedicated to video display. For example, the VRAM 105 functions as a frame buffer that temporarily holds a two-dimensional image generated by the GPU 104 and also temporarily holds data necessary for various processes of the GPU 104. The two-dimensional image held in the VRAM 105 is transferred to the monitor 1 frame by frame via the video interface 106.

  The monitor 1 rewrites the screen at a frame rate of 60 fps, for example, in accordance with the transfer of the two-dimensional image frame by frame from the VRAM 105. Thereby, a game image is displayed on the screen of the monitor 1. When the aim mark is included in the two-dimensional image, the aim mark is displayed in an overlay at a predetermined position on the screen. The aiming mark is a mark that represents the aiming position of the gun controller 3 that is directed to the screen of the monitor 1 by the operation of the player. For example, when an object such as a background or an enemy character is displayed on the entire screen, and the gun controller 3 is pointed at the screen, the aiming mark is displayed in a state of being overlapped with these objects. Note that different game images may be displayed on the screens of the two monitors 1 depending on, for example, the number of players playing the game and the game mode.

  The image sensor 33 captures infrared light from the plurality of LEDs 2 and outputs a two-dimensional captured image. For example, a CCD image sensor or a CMOS image sensor is applied. The image sensor 33 receives the infrared light of the LED 2 via an optical lens and an infrared filter, and outputs a captured image capturing a bright spot of infrared light not including noise such as visible light to the image processing unit 34. To do.

  The image processing unit 34 performs image processing on the captured image from the image sensor 33 and detects the aiming position of the gun controller 3 on the screen of the monitor 1 based on the position of the bright spot in the captured image. As a result, the image processing unit 34 outputs aiming coordinate information indicating the coordinates of the aiming position on the screen. Such an aim position detection process by the image processing unit 34 is realized by a known technique (the technique described in Japanese Patent Laid-Open No. 11-305935).

  When the aiming coordinate information output in this way is transmitted to the CPU 101, an aiming mark is displayed on the screen of the monitor 1 corresponding to the aiming position of the gun controller 3. At this time, when the trigger 31 is operated by the player, a trigger operation signal from the trigger switch 32 is transmitted to the CPU 101. Then, the CPU 101 acquires trigger operation information, and a game image that appears at the aiming position is displayed on the screen of the monitor 1. On the other hand, for example, when a bright spot cannot be detected in a predetermined area of the captured image, the image processing unit 34 determines that the aiming position is outside the screen. As a result, the aiming mark is not displayed on the screen of the monitor 1.

  Although details will be described later, when the two gun controllers 3 are in a usable state, under a predetermined condition, the CPU 101 determines the other gun controller 3 from the timing of the trigger operation of one gun controller 3. Time until the trigger operation timing. And CPU101 operates a timer, for example, when the trigger operation information of one gun controller 3 is acquired. Thereby, the CPU 101 can determine whether or not the trigger operation of the other gun controller 3 has been performed before a predetermined time elapses after the trigger operation of one gun controller 3 is performed.

  The pedal switch 42 outputs a pedal operation signal in conjunction with the kicking operation when the player performs an appropriate kicking operation on the kick pedal 41 when a kick input to the foot kick input device 4 is possible. When a pedal operation signal from the pedal switch 42 is transmitted to the CPU 101, the CPU 101 acquires kick input detection information. The detection information includes input timing, input intensity (load), and input duration time. For example, when the CPU 101 detects an input via the pedal switch 42, the CPU 101 activates a timer, measures the time during which the input detection by the pedal switch 42 is continued, and obtains the input duration time. Based on the kick input detection information, a game image in which a target dynamic character is stepped on or a static object is kicked is displayed on the screen of the monitor 1.

  Next, an example of a gun shooting game executed by the game apparatus A configured as described above will be described with reference to FIGS.

  When the game starts, a game image is displayed on the screen of the monitor 1 and the game proceeds. The game image is a virtual game space displayed on the screen of the monitor 1 as a two-dimensional image. In the game image, an object such as a background or an object is displayed, and a target such as an enemy character is displayed. At the start of the game, for example, it is set so that the player can operate only one gun controller 3 (hereinafter referred to as “first gun controller 3A” as appropriate). The player directs the gun controller 3 toward the screen of the monitor 1 to aim the target and perform an operation of pulling the trigger 31. Here, for example, when the CPU 101 acquires the trigger operation information, in the two-dimensional image displayed on the screen, whether or not the area occupied by the target and the shooting range centered on the coordinates of the aiming position are displayed in an overlapping manner. Is detected. The CPU 101 determines that the bullet has hit the target if the area occupied by the target and the shooting range overlap, and the bullet hits the target if the area occupied by the target and the shooting range do not overlap. Judge that it did not. A method for determining whether or not a bullet hits such a target is a well-known technique.

  A predetermined physical strength value is set for each of the player character and the enemy character, and the player character and the enemy character are set to fall when the physical strength value becomes zero. The CPU 101 manages parameters such as the physical strength value, position information, and attack power of the player character and enemy character. When it is determined that a bullet has hit an enemy character in the virtual game space by the operation of the player's trigger 31, the CPU 101 performs an effect process by a gun attack defined in the game program, and the monitor 1 screen displays the enemy character. A game image in which the character is damaged is displayed. Then, the CPU 101 decreases the stamina value of the shot enemy character by a predetermined number, and when the stamina value becomes 0, the CPU 101 puts the enemy character in a defeated state. FIG. 5 shows an example of various parameters such as the physical strength value and attack power of the player character. The attack power by the player character is varied depending on the type of weapon and the attack content. FIG. 6 shows an example of various parameters such as the physical strength value and attack power of the enemy character. These parameters relating to the player character and the enemy character are stored in the ROM 102, and are read from the ROM 102 and stored in the RAM 103 during the execution of the game.

  As the game progresses, a predetermined virtual game space is generated for each game stage. In the virtual game space, objects such as backgrounds and objects, enemy characters, and the like are arranged at predetermined positions. As described above, the game image displayed on the monitor 1 is a two-dimensional image obtained by imaging the virtual game space from the virtual camera arranged on the player character. The player character is controlled to move in a virtual game space, for example, a course selected by a player's operation or a predetermined course for each game stage. The enemy character is controlled to move in a virtual game space for each game stage, for example, along a predetermined course, or to move by a well-known AI (artificial intelligence) set for the enemy character. The enemy character is set as, for example, a zombie that has been revived, and the zombie (enemy character) approaches and attacks the player character in order to make the player character's physical strength value 0 in the game image. come. When the enemy character approaches a certain range (for example, 3 m: corresponding to the attack action range 3 m in FIG. 6) from the virtual camera (player character), the player character can be damaged by the attack from the enemy character. Then, the CPU 101 decreases the physical strength value of the damaged player character by a predetermined number, and when the physical strength value becomes 0, the player character falls. When the player character falls three times, the game ends. If the enemy characters approaching one after another can be quickly defeated and the attack from the enemy characters can be avoided, the clearing of one game stage is established and the next game stage can be advanced. Note that all or part of the player character may be displayed in the game image, or only the gun possessed by the player character may be displayed.

  When a predetermined condition is satisfied in the progress of the game, the second gun controller 3 (hereinafter referred to as “second gun controller 3B” as appropriate) can be used. As a condition for permitting the use of the second gun controller 3B, for example, a case where a second gun item that appears when a special enemy character is defeated is acquired. Further, when a predetermined condition is satisfied, the second gun controller 3B is released from the use permission and cannot be used. Conditions for releasing the use permission of the second gun controller 3B include, for example, a case where a predetermined time has elapsed since the use of the second gun controller 3B became possible, and a case where the player character has received a certain amount of damage. Is mentioned. FIG. 7 is a flowchart showing a procedure for permitting or not using the second gun controller 3B.

  As shown in FIG. 7, first, the CPU 101 determines whether or not a condition for permitting the use of the second gun controller 3B is satisfied (S10). When the conditions for permitting use of the second gun controller 3B are satisfied (S10: YES), the second gun controller 3B can be used (the state in which the second gun controller 3B can be used is referred to as “two-flag flag ON” as appropriate). ), The display of the aiming mark of the second gun controller 3B on the screen of the monitor 1 and the detection of the trigger operation by the second gun controller 3B are performed (S11). Next, it is determined whether or not the second gun controller 3B is usable (whether or not the 2-chome flag is on) (S12). Here, when it is determined that the two-flag flag is not ON (S12: NO), the use permission / inhibition process of the second gun controller 3B is terminated assuming that the second gun controller 3B cannot be used. If it is determined in step S12 that the two-flag flag is ON (S12: YES), it is then determined whether or not a condition for canceling the use permission of the second gun controller 3B is satisfied (S13). Here, when the condition for canceling the use permission of the second gun controller 3B is not satisfied (S13: NO), the use permission / refusal processing of the second gun controller 3B is ended assuming that the 2-chome flag is ON. On the other hand, if the condition for canceling the use permission of the second gun controller 3B is satisfied in step S13 (S13: YES), the second gun controller 3B is disabled (two-flag flag off) (S14), and the monitor 1 In this screen, the display of the aiming mark of the second gun controller 3B and the detection of the trigger operation by the second gun controller 3B are not performed. Then, the use permission / refusal processing of the second gun controller 3B is terminated. The process shown in the flowchart of FIG. 7 is executed for each frame. Further, whether or not the second gun controller 3B is used is controlled by the CPU 101.

  When the muzzles of the first and second gun controllers 3A and 3B are pointed toward the screen of the monitor 1, aiming marks are generated corresponding to the aiming positions of these gun controllers 3A and 3B, and the aiming marks are displayed on the game image. FIG. 8 is a flowchart showing a procedure for displaying the aiming marks of the first and second gun controllers 3A and 3B.

  First, aiming coordinate information (sighting position) for the screens of the gun controllers 3A and 3B is obtained by the image processing unit 34 described above, and this aiming coordinate information is transmitted to the CPU 101 (S20). Next, it is determined whether or not the 2nd flag is on (S21). Here, when it is determined that the two-digit flag is not ON (S21: NO), the CPU 101 generates only the aiming mark corresponding to the aiming position of the first gun controller 3A and displays it on the game image (S22). FIG. 9 is a diagram showing a game image when the aiming mark MA of the first gun controller 3A is displayed. The aiming mark MA is displayed as a double circle of a predetermined size centered on the aiming position PA of the first gun controller 3A, for example. When the aiming mark MA is displayed, the gun type of the first gun controller 3A is set to a hand gun (S23), and in a state of attacking with a normal attack power (attack power 30) by a trigger operation, as will be described later. is there. When the aiming mark MA of the first gun controller 3A is displayed, the aiming mark display process ends.

If it is determined in step S21 that the 2-chome flag is ON (S21: YES), it is determined whether or not the distance between the aiming positions of the first and second gun controllers 3A and 3B is equal to or less than a predetermined value (S24). ). Prior to this determination, the CPU 101 calculates the distance between the aiming position of the first gun controller 3A and the aiming position of the second gun controller 3B. As shown in FIG. 10, when the coordinates of the aiming position PA of the first gun controller 3A are (Xa, Ya) and the coordinates of the aiming position PB of the second gun controller 3B are (Xb, Yb), the aiming positions PA, PB The distance d between them is d = √ {(Xb−Xa) ² + (Yb−Ya) ² }.

  When the distance d between the aiming positions PA and PB exceeds, for example, a predetermined value d0 set in advance (S24: NO), that is, when d> d0, aiming of the first gun controller 3A and aiming of the second gun controller 3B Are considered not to overlap. Then, the CPU 101 generates aiming marks corresponding to the aiming positions PA and PB of the first and second gun controllers 3A and 3B and displays them on the game image (S25). FIG. 11 is a diagram showing a game image when the aiming marks MA and MB of the first and second gun controllers 3A and 3B are displayed. The aiming mark MB is displayed as a double circle centered on the aiming position PB of the second gun controller 3B, for example, and has the same size as the aiming mark MA. When the aiming marks MA and MB are displayed, the gun types of the first and second gun controllers 3A and 3B are both set to hand guns (S26), and the normal attack power ( This is a state of attacking with attack power 30). When the aim marks MA and MB of the first and second gun controllers 3A and 3B are displayed, the aim mark display process is ended.

  On the other hand, when the distance d between the aiming positions PA and PB is, for example, a predetermined value d0 or less set in advance (S24: YES), that is, when d ≦ d0, the aim of the first gun controller 3A and the second gun controller It is considered that the 3B aiming is overlapped, and a special aiming mark display process is performed instead of the aiming marks MA and MB (S27). Details of the display processing of the special aiming mark will be described later. When the special sighting mark display process in step S27 is executed, the sighting mark display process ends. The process shown in the flowchart of FIG. 8 is executed for each frame.

  FIG. 12 is a flowchart showing the procedure of the special aiming mark display process (the processing content of step S27 in FIG. 8).

  First, the CPU 101 calculates the special aim position where the special aim mark is to be displayed (S30). The special aim mark is generated at a special aim position determined based on the aim positions PA and PB of the first and second gun controllers 3A and 3B, for example. In the present embodiment, the special aiming position is set to an intermediate position between the aiming positions PA and PB of the first and second gun controllers 3A and 3B. Therefore, as shown in FIG. 13, if the coordinates of the aiming position PA of the first gun controller 3A are (Xa, Ya) and the coordinates of the aiming position PB of the second gun controller 3B are (Xb, Yb), the special aiming position The coordinates (Xs, Ys) of Ps are Xs = (Xa + Xb) / 2 and Ys = (Ya + Yb) / 2.

  Next, the CPU 101 generates a special aiming mark at the special aiming position and displays it on the game image (S31). FIG. 14 is a diagram showing a game image when the special aiming mark MS is displayed. The special aim mark MS is displayed, for example, as a double circle of a predetermined size centered on the special aim position PS. The size of the special aiming mark MS is set larger than the size of the aiming marks MA and MB described above with reference to FIG. Thereby, the player can quickly recognize that the special aiming mark MS is displayed. The special aiming mark MS may be different from the normal aiming marks MA and MB. For example, the special aiming mark MS may be identified by making the color and shape of the special aiming mark MS different from the aiming marks MA and MB. . Although details will be described later, when the special aiming mark MS is displayed, the special attack process can be executed in accordance with the trigger operation of the first and second controllers 3A and 3B. When the special aim mark MS is displayed, the special aim mark display process ends.

  Next, the procedure of attack processing performed in response to the trigger operation when the gun controller 3 is aimed at the screen will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the special aiming mark MS is displayed (S40). When the special aiming mark MS is not displayed (S40: NO), when any of the trigger operations of the first and second controllers 3A, 3B is performed (S41: YES), the CPU 101 detects the corresponding aiming position PA, A normal attack process is executed with normal attack power toward any of the PBs (S42). There are several variations of the normal attack processing executed here. First, if the two-flag flag is not on, the gun type of the first gun controller 3A is set to the hand gun as described in step S23 of FIG. 8, and the aiming position PA is set by the trigger operation of the first gun controller 3A. Normal attack processing is performed toward If the two-flag flag is ON, the gun type of the first and second gun controllers 3A and 3B is set to the hand gun as described in step S26 of FIG. 8, and the first and second gun controllers 3A are set. , 3B, the normal attack process is performed toward one or both of the aiming positions PA and PB where the trigger operation is performed. Regarding the contents of the normal attack process, the range in which the aiming mark MA (MB) is displayed is set as the shooting range, and as shown in FIGS. 9 and 11, the area occupied by the enemy character 10 in the game image If the aiming mark MA (MB) is displayed in an overlapping manner, it means that the bullet has hit the enemy character 10. When the normal attack process of step S42 is executed, the attack process ends.

  On the other hand, when the special aiming mark MS is displayed (S40: YES), if both the first and second gun controllers 3A and 3B are triggered simultaneously, a special attack process described later is executed. Here, whether or not the trigger operation is performed at the same time depends on whether a predetermined time elapses after the trigger operation of one of the first and second gun controllers 3A and 3B is performed. This is determined by whether or not the trigger operation of the other gun controller is performed. Here, the predetermined time is set to about 0.2 seconds (equivalent to 12 frames when the frame rate is 60 fps, for example). That is, with regard to the simultaneous determination of the trigger operation, a slight deviation of the trigger operation in both gun controllers 3A and 3B is allowed.

  When the special aim mark MS is displayed, if a trigger operation of one of the first and second gun controllers 3A and 3B is detected (S43: YES), the CPU 101 sets a timer. Operate (S44). Thereafter, when a trigger operation of the other gun controller 3 is detected before a predetermined time elapses from the timer operation (S45: NO, S46: YES), the CPU 101 executes a special attack process (S47). When the trigger operation of the other gun controller 3 is not detected in step S46 (S46: NO), the process returns to step S45 and continues to detect the presence or absence of the other trigger operation until the predetermined time has elapsed.

  FIG. 16 is an attack processing table that defines the content of the attack processing, and is stored in the ROM 102. During the game execution, the table is read from the ROM 102 and stored in the RAM 103. When the type of attack processing (normal attack processing or special attack processing) is determined, the CPU 101 calls data corresponding to the determined attack processing type from the attack processing table and executes the attack processing.

  Regarding the special attack process, the gun type is set to bazooka, and the attack is performed toward the special aiming position PS. For the special attack process, the range in which the special aim mark MS is displayed is set as the shooting range. As shown in FIG. 14, the area occupied by the enemy character 10 in the game image, the special aim mark MS, If they are displayed in an overlapping manner, a bullet has hit the enemy character 10. The attack power of the special attack process is set to be larger (attack power 100) than the attack power of the normal attack process. Therefore, when a bullet hits the enemy character by the special attack process, it is possible to give more damage to the enemy character than in the normal attack process. The attack power of the special attack process (bazooka) is set to about three times the attack power of the normal attack process (hand gun), for example (see FIG. 5).

  Returning to FIG. 15, when the special attack process of step S47 is executed, the timer operated in step S44 is reset (S48), and the attack process ends.

  In step S45, when the trigger operation of the other gun controller 3 is not detected before the predetermined time elapses from the timer operation (S45: YES), the CPU 101 performs the one gun controller that performed the trigger operation in step S43. The normal attack process is executed toward the aiming position PA (PB) 3 (S49). When the normal attack process is executed, the timer operated in step S44 is reset (S48), and the attack process ends.

  According to the game apparatus A of the present embodiment, the second second gun controller 3B can be used only when a predetermined condition is satisfied during the progress of the game. When the two gun controllers 3A and 3B are usable, the player can shoot with both hands using these gun controllers 3A and 3B. Shooting with both hands has the advantage of making it easier to defeat the enemy, and the player can obtain a refreshing feeling from continuous shooting.

  When the two gun controllers 3A and 3B are usable, the aiming marks of the gun controllers 3A and 3B can be obtained by overlapping the aiming of these gun controllers 3A and 3B (the aiming positions PA and PB are brought close to a predetermined range). A special aiming mark MS is displayed in place of MA and MB. When the trigger operation of the two gun controllers 3A and 3B is performed simultaneously (for example, within 0.2 seconds) while the special aiming mark MS is displayed, a special attack process having a high attack power is executed. . Therefore, for example, when a strong enemy character that cannot be defeated unless large damage is given appears, the player appropriately operates the first and second gun controllers 3A and 3B to execute the special attack process. The enemy character can be easily defeated.

  As can be understood from the above, in the game apparatus A, the player can have a unique strategy and capture in the progress of the game by properly using the normal attack process and the special attack process depending on the situation. New game characteristics can be provided.

  As described above, the time when the two gun controllers 3A and 3B can be used is limited. For this reason, the state in which the two gun controllers 3A and 3B can be used is a special state in which there is a stimulus in the progress of the entire game, and the fun of the game can be enhanced.

  When the first and second gun controllers 3A and 3B are usable, the first and second gun controllers 3A and 3B are displayed when the special aiming mark MS is displayed, that is, when the two aiming objects are considered to overlap. The attack power in the special attack processing may be changed according to the relative positional relationship between the aiming positions PA and PB.

  As an example of changing the attack power of the special attack process, the attack power of the special attack process is changed in two stages according to the relative directional relationship between the aiming positions PA and PB of the first and second gun controllers 3A and 3B. And a method of displaying different special aiming marks. For example, the CPU 101 determines whether two sights overlap in the left-right direction and when they overlap in the up-down direction, and changes the display mode of the special sighting mark in these two cases.

  FIG. 17 is a flowchart showing the procedure of the special sighting mark display process (the processing content of step S27 in FIG. 8) when the display mode of the special sighting mark is different depending on the direction in which the two sightings overlap. FIG. 18 is a diagram for explaining a method of determining the direction in which two aiming overlaps.

  As shown in FIG. 17, first, a special aiming position is calculated (S50). The special aiming position is set to an intermediate position between the two aiming positions PA and PB as described above with reference to step S30 in FIG.

Next, the direction in which the two sights overlap is determined (S51). Here, as shown in FIG. 18, a circle whose diameter is a line segment connecting the aiming positions PA and PB with the special aiming position PS as the center is formed, and this circle is arcuately positioned horizontally and vertically. Are divided into regions R1 and R2. Then, whether the two aiming points overlap in the left-right direction or the up-down direction is determined depending on whether the aiming positions PA, PB are in the regions R1, R2. Specifically, with reference to the top of the circle, 0 ° ≦ R2 <45 °, 135 ° ≦ R2 <225 °, 315 ° ≦ R2 <360 °, 45 ° ≦ R1 <135 °, 225 ° ≦ R1 Assuming <315 °, when the aiming positions PA and PB are in the region R1, it is determined that the two aiming points overlap in the left-right direction. When the aiming positions PA and PB are in the region R2, it is determined that the two aiming points overlap in the vertical direction.

  FIG. 19 is a special attack processing table that defines the contents of the special attack processing. When the aim is overlapped in the left-right direction, the attack power is larger and the shooting range is set larger than when the aim is overlapped in the up-down direction. Further, for example, the special aiming mark MS1 and the special aiming mark MS1 and the special aiming mark MS1 when the aiming is overlapped in the horizontal direction are made larger than the size of the special aiming mark MS2 when the aiming is overlapped in the vertical direction. MS2 can be identified.

  If it is determined in step S51 that the aiming is overlapped in the left-right direction (S51: YES), the CPU 101 generates a special aiming mark MS1 at the special aiming position PS and displays it on the game image (S52). If it is determined in step S51 that the aiming overlaps in the vertical direction (S51: NO), the CPU 101 generates a special aiming mark MS2 at the special aiming position PS and displays it on the game image (S53). When one of the special aiming marks MS1 and MS2 is displayed, the special aiming mark display process ends.

  When either one of the special aiming marks MS1 and MS2 is displayed and the trigger operations of the gun controllers 3A and 3B are performed at the same time, the special attack process with the content corresponding to the special aiming mark MS1 (MS2) is performed. Executed.

  As described above, according to the configuration in which the attack power in the special attack process is changed according to the relative positional relationship between the aiming positions PA and PB, the special attack process having a greater attack power is executed for the player. Since the willingness to aim can be stimulated, the interest of the game can be enhanced.

  Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above-described embodiment. The specific configuration of each part of the game device according to the present invention can be variously modified without departing from the spirit of the invention.

  In the above embodiment, the special aiming mark is generated around the intermediate position between the aiming positions of the two gun controllers. Instead, for example, the special aiming mark is generated around the aiming position of one gun controller. It is good also as a structure to be. In short, the special aiming mark is a special aiming position determined based on at least one of the aiming positions (first and second aiming positions) with respect to the display means of the first and second controllers. Any configuration can be used.

  In the above-described embodiment, the case where the shape of the special aiming mark is circular has been described as an example. However, the present invention is not limited to this, and the special aiming mark may be other shapes such as a polygon and a cross Also good. Further, the display size of the special aiming mark may be changed stepwise or linearly according to the distance between the two aiming positions. Furthermore, the shape of the special aiming mark may be changed according to the distance between the two aiming positions.

  In the above embodiment, the special aiming process is executed when the special aiming mark is displayed and the trigger operation is simultaneously performed. However, the present invention is not limited to this. . For example, when a special aiming mark is displayed, a special attack process may be executed when a trigger operation of one of the gun controllers is performed.

  In the above embodiment, when the special aiming mark is displayed, as an example of changing the attack power of the special attack process according to the relative positional relationship between the two aiming positions, the attack power is divided into two stages according to the direction in which the aiming is overlapped. However, the method for changing the attack power is not limited to this. For example, the attack power of the special attack process may be changed stepwise or linearly according to the distance between two aiming positions. Note that the display mode of the special aiming mark may be changed according to the change of the attack power of the special attack process, but the display mode is not necessarily different.

  In the above embodiment, the display size of the special aiming mark is larger than the display size of the normal aiming mark. On the contrary, the size of the special aiming mark is smaller than the size of the normal aiming mark. May be. In short, the size of the special aiming mark may be different from the size of the normal aiming mark.

  In the embodiment described above, the aiming mark and the special aiming mark for indicating the aiming position and the special aiming position are configured to be displayed on the game image, but the aiming mark and the like are not necessarily displayed on the game image. In the game control, it is only necessary that the CPU can acquire the aiming coordinate information and specify the aiming position or the special aiming position, and a predetermined attack process may be performed on the aiming position or the like by an input operation of the controller.

  In the above-described embodiment, an example where the game device is configured as an arcade type game device has been described. However, the present invention is not limited to this. The present invention can be applied regardless of the type of game device. For example, the present invention can be applied to a case where a game is played on a home game device or a portable game device. In the case of a home game device, for example, a game program or the like recorded on a recording medium such as an optical disk is read by a reading device provided in the game device, and the game is executed.

  In the above embodiment, the gun shooting game has been described as an example, but the present invention is not limited to this. The present invention can be applied to a game that can exert an effect on the progress of a game with respect to an aim aimed at a monitor screen by operating a controller. For example, a fighting game, a battle game, a sports game, or a target game Etc. can be applied. Further, as a controller used in these games, a controller composed of buttons, levers and the like can be adopted. In the case of a controller including a button or a lever, for example, the display position (aim position) of the aiming mark may be changed by operating the lever.
