Description

  The present invention relates to a game apparatus, and more particularly, to a rifle game apparatus that executes a battle game in which a user who uses a simulated rifle shoots on a monitor in a simulated manner.

  Conventionally, a game screen is displayed on a screen of a monitor or the like, and the object displayed on the monitor is irradiated with an electric beam from a simulated gun, thereby performing a hit determination on the object. Rifle game devices are known.

For example, Patent Document 1 describes that a simulated gun of a video game apparatus that executes a rifle game is provided with a scope that displays an object to be shot in an enlarged manner to improve the resolution of the enlarged display.
JP 2004-049412 A

  However, in the video game apparatus of Patent Document 1, the simulated gun used is limited to the function as a gun, so the game content to be executed cannot exceed the category of rifle games. In other words, in such a video game machine, the functions for the attack of the simulated gun provided in the video game are limited, so that the content of the game executed by the video game machine is also limited. We cannot provide a game machine that can be expected to develop.

  Furthermore, when a function that can be used as a sword in the game is added to the simulated gun of such a rifle game, for example, a function that can be used as a sword in the game, whether the user intended to use the sword during the game, It becomes difficult to determine whether the rifle was used for shooting.

  An object of the present invention is to provide a game device that can be expected to be developed in various ways by adding a new function for a pseudo-attack in a battle game to a simulated gun provided in the game device. The purpose is to improve the interest of the player.

(1) a game control unit (for example, a control unit 150 to be described later) that executes a game in response to an input from the user;
A monitor unit (for example, a monitor unit 200 described later) for displaying image data of a game executed by the game control unit;
A trigger unit (for example, a trigger to be described later) that irradiates an object displayed on the monitor unit with a light beam (for example, an electromagnetic wave to be described later, including infrared rays) and receives an operation from the user. A gun-type controller (for example, a gun-type controller 500 described later),
A sensor (for example, an infrared camera sensor 400, an I / O port described later) that images the irradiated light beam, outputs coordinate data indicating the position coordinates of the monitor unit, and transmits the output coordinate data to the game control unit 180), and
The gun-type controller has a shape of a simulated sword arranged parallel to the longitudinal direction, and detects an acceleration by a user operation and digitizes the acceleration (for example, an acceleration described later) A sensor 530), and when the acceleration is detected, a numerical value of the acceleration is transmitted as acceleration data to the game control unit;
The game control unit controls the received coordinate data and the acceleration data as game input data.

In the game device of (1), when the gun-type controller used in the game device detects a predetermined acceleration by a user operation and digitizes the acceleration, the acceleration value is converted into acceleration data when the acceleration is detected. To the game control unit. And a game control part controls the said acceleration data transmitted with the coordinate data from the light irradiated from the gun-type controller as game input data.
Therefore, it is possible not only to cause the gun-type controller to function as a gun used in the game, but also to use acceleration applied by the user to a predetermined gun-type controller as game input data. That is, since the acceleration data including the direction and magnitude of the acceleration operated by the user can be handled as input data to the game, this game apparatus is a pseudo-game machine used in, for example, a gun-type controller game. It is possible to provide a game with a special sword. As a result, by adding new functions to the simulated guns provided in the game device, it is possible to provide a game device that can be expected to be developed in various ways, and to improve the interest of the player than before. It is.

(2) a threshold data storage unit (for example, a data storage unit 190 to be described later) that stores threshold data for determining whether to control the acceleration data received by the game control unit as the game input data;
The game device according to (1), wherein the game control unit determines whether to control the received acceleration data as the game input data based on the threshold data.

According to the invention described in (2), the game device includes a threshold data storage unit that stores threshold data for determining whether to control acceleration data received by the game control unit as game input data. The control unit determines whether to control the received acceleration data as game input data based on the threshold data.
Therefore, when the acceleration applied by the user to the gun-type controller is smaller than the threshold data, it is not controlled as game input data, so that the user simply functions the gun-type controller as a gun. When operated, the acceleration for the gun-type controller generated for this purpose is not handled as game input data for the sword. As a result, this acceleration can be handled as game input data only when the user applies acceleration to the gun-type controller in consideration of the use of the sword.

(3) a sword image data storage unit (for example, a data storage unit 190 described later) in which sword image data indicating that a sword is used in a pseudo manner with respect to the object displayed on the monitor unit is provided;
The game device according to (1) or (2), wherein when the game control unit controls the received acceleration data as the game input data, the corresponding sword image data is displayed on the monitor unit.

According to the invention described in (3), the game device includes the sword image data storage unit in which the sword image data indicating that the sword is used in a pseudo manner with respect to the object displayed on the monitor unit is stored. When the game control unit controls the received acceleration data as the game input data, the corresponding sword image data is displayed on the monitor unit.
Therefore, when the user applies acceleration to the gun-type controller, it is possible to display an image image on the monitor as if the sword was used on the object. It becomes possible to make a pseudo-experience as if you are using.

(4) A shooting image data storage unit (for example, a data storage unit 190 to be described later) in which shooting image data indicating that the target displayed on the monitor unit has been artificially shot is stored.
The game device according to (2) or (3), wherein the game control unit displays corresponding shooting image data on the monitor unit in response to receiving the coordinate data.

According to the invention described in (4), the game apparatus includes a shooting image data storage unit in which shooting image data indicating that the target displayed on the monitor unit has been artificially shot is stored, In response to receiving the coordinate data, the control unit displays the corresponding shooting image data on the monitor unit.
Therefore, in response to the user operating the trigger unit of the gun-type controller, it is possible to display an image image as if the object was shot on the monitor unit. It is possible to have a simulated experience as if you were shooting at.

(5) The game control unit determines whether or not the user has operated the trigger unit for a predetermined time when the numerical value of the acceleration data is equal to or greater than the threshold value of the threshold data. Control unit 150),
When the bayonet determination unit determines that the user has operated the trigger unit, the game control unit does not display the corresponding sword image data on the monitor unit, and does not display the corresponding shooting image data. Is displayed on the monitor unit. The game device according to (4).

According to the invention described in (5), when the numerical value of the acceleration data is equal to or greater than the threshold value of the threshold data, the game control unit determines whether or not there is a user operation on the trigger unit for a predetermined time, If it is determined that the user has operated, the game control unit displays the corresponding shooting image data on the monitor unit without displaying the corresponding sword image data on the monitor unit.
Therefore, even if acceleration is applied from the user to the gun-type controller, unless the user intentionally applies acceleration, the sword image data is not displayed on the monitor unit. If a sword is used, the user can be made unaware.
When the gun-type controller has a function as a pseudo gun and a function as a sword as in this game device, there is a problem in controlling which function the user uses. is there. In this game apparatus, the bayonet determination unit can determine which function the user is using by determining whether or not the user has operated the trigger unit for a predetermined time.

  According to the present invention, by providing a new function to the simulated gun provided in the game apparatus, a game apparatus that can be expected to be developed in various ways is provided, and the interest of the player is improved as compared with the past. It is possible.

  The battle game realized by the control unit 150 is a game in which a user shoots at an object on the battle game or uses a sword to attack the object in response to an input from the gun-type controller 500. It is. For example, the target of attack in the battle game is an enemy character (hereinafter referred to as “enemy character”) to which the user battles, and this enemy character has a vitality value indicating how much the enemy character disappears when attacked. Are related in advance. Then, the user shoots the enemy character or uses a sword to reduce the vitality value of the enemy character. Here, the enemy character reduces the vitality value previously related to the user by attacking the user. When the vitality value of the user becomes 0, the battle game is ended.

  The data storage unit 190 realizes data processed by the control unit 150, image data, game parameters (user vitality values, parameters indicating enemy character vitality values, user scores, etc.), threshold data described later, and a battle game. It may be a hard disk in which a program or the like is stored, or a storage device of the RAM 170. The image data stored in the data storage unit 190 may be image data related to a character such as an enemy character, which is a target used in a battle game. Further, the image data may be shooting image data or sword image data displayed under a predetermined condition when the user uses the gun-type controller 500, or relates to an item or the like that restores the user's life force value. It may be image data. In addition, as will be described with reference to FIGS. 8 and 9, image data related to a background image that is displayed in a simulated manner in a battle game and image data related to an obstacle in progress of the game may be included.

  The image data stored in the data storage unit 190 may be data that realizes three-dimensional graphics using polygons. That is, polygon data and texture data are stored in the data storage unit 190 as image data, and a character representing the texture data pasted on the polygon is displayed on the monitor unit 200.

  The monitor unit 200 is a device that displays the image data controlled by the control unit 150, and may be a display device such as a liquid crystal display, a plasma display, or an organic EL display. The infrared camera sensor 400 constantly shoots the screen of the monitor unit 200 and detects infrared rays emitted from the gun-type controller 500. In a preferred embodiment of the present invention, the electromagnetic wave irradiated by the gun-type controller 500 is, for example, an electromagnetic wave in the vicinity of infrared and infrared wavelength bands, but the type of electromagnetic wave irradiated by the gun-type controller 500 is limited to infrared. Not.

  The infrared camera sensor 400 images electromagnetic waves such as infrared rays, analyzes the position where the electromagnetic waves are irradiated on the monitor unit 200 as coordinate data, and transmits the coordinate data to the control unit 150. That is, the infrared camera sensor 400 associates the vertical and horizontal positions of the screen display area surface of the monitor unit 200 with the vertical and horizontal position coordinates of the CCD elements constituting the infrared camera sensor 400, and the CCD elements that have captured infrared rays. The position of the monitor unit 200 is calculated from the coordinates. Here, the infrared camera sensor 400 may capture infrared light and transmit the captured data to the control unit 150, and the control unit 150 may analyze the position of the infrared light on the monitor unit 200 as coordinate data. As will be described later, the infrared camera sensor 400 images the first electromagnetic wave and the second electromagnetic wave as electromagnetic waves to be imaged, distinguishes these electromagnetic waves, and transmits the coordinate data to the control unit 150.

  The start operation unit 600 is a device that accepts insertion of a coin or the like from a user and transmits a signal indicating that a coin has been inserted to the control unit 150.

  FIG. 3 is an external view of the gun-type controller 500. The gun-type controller 500 is a device that accepts input from a user for a battle game. The gun-type controller 500 includes a light-emitting unit 510 that emits electromagnetic waves such as infrared rays, a trigger unit 520 that receives an input from a user, and an acceleration sensor 530 that detects acceleration applied to the gun-type controller 500.

  The gun-type controller 500 has the appearance of a gun such as a rifle, gun, or pistol, and a simulated sword 540 that protrudes in a direction parallel to the longitudinal direction is disposed near the muzzle. The gun-type controller 500 may be connected to the game casing 100 via a wire via the I / O port 180 to realize communication, but the game casing 100 includes a receiving unit such as an access point, a wireless LAN, Wireless communication may be performed using Bluetooth (registered trademark) or the like.

  The acceleration sensor 530 of the gun-type controller 500 detects the direction and magnitude of the movement made by the user with respect to the gun-type controller 500 as acceleration, and transmits the direction and magnitude to the control unit 150 as acceleration data. To do. Details of the acceleration sensor 530 will be described later with reference to FIG. As will be described later, the gun-type controller 500 includes the acceleration sensor 530, so that the action is detected as acceleration in response to the user performing an action using the sword. Process as acceleration data.

  The gun-type controller 500 includes a light emitting unit 510 that emits electromagnetic waves such as infrared rays. The light emitting unit 510 is always irradiated with a predetermined electromagnetic wave (hereinafter referred to as “first electromagnetic wave”), and when the trigger unit 520 is operated by the user, electromagnetic waves in different frequency bands (hereinafter referred to as “second electromagnetic wave”). Of electromagnetic waves ”). That is, as will be described later, when the user uses the gun-type controller 500 as a sword, the sword coordinate data indicating the location of the gun-type controller 500 (the location where the sword is used or the trajectory of the cut) used by the user is controlled. In order for 150 to receive, the light emission part 510 always irradiates the 1st electromagnetic wave in order to detect which position on the monitor part 200 the tip of a sword is. The irradiated electromagnetic wave is received by the infrared camera sensor 400 and is transmitted to the control unit 150 by the infrared camera sensor 400. Normally, the control unit 150 does not determine that it is intentional use of a sword, so the control unit 150 does not perform any particular processing. However, when the acceleration data is received, the user intentionally uses the sword. In determination, the sword coordinate data and the acceleration data are processed by the control unit 150.

  When an operation from the user is received with respect to the trigger unit 520 of the gun-type controller 500, the light emitting unit 510 irradiates the second electromagnetic wave different from normal in order to determine that the user has shot, The infrared camera sensor 400 receives the second electromagnetic wave and transmits coordinate data (by shooting) to the control unit 150.

[Main flow processing]
Based on FIG. 4, a main flow process executed by the control unit 150 of the game apparatus 1 will be described. The game apparatus 1 receives a coin or the like inserted in the start operation unit 600 and presses a game start switch or the like, so that the start operation unit 600 accepts it and transmits a signal indicating that to the control unit 150, whereby the user It is determined that an operation has been received from (step S100). The control unit 150 reads out a program related to the game start from the data storage unit 190, thereby realizing the game execution unit 151 and performing a game start process (step S101).

  The control unit 150 displays image data such as the background of the battle game on the monitor unit 200, and reads out and displays image data of an object (enemy character or the like) with which the virtual user corresponding to the user battles from the data storage unit 190. The object appearance process is executed (step S102). Here, the control unit 150 executes an attack determination process for performing an attack determination on the object displayed on the monitor unit 200 based on data input by the user operating the gun-type controller 500. (Step S103).

  The control unit 150 performs an enemy character attack process in which the enemy character reduces the life force value of the virtual user in the battle game. If the enemy character decreases the life force value of the virtual user, the attack process of the enemy character is performed. Thus, a damage determination process for determining whether the vitality value of the virtual user has become 0 or less is executed (step S104).

  Next, the control unit 150 determines whether the game end condition is met (step S105). The game end condition is, for example, the case where the vitality value of the virtual user becomes 0 or less as described above, or the case where the game progress ends at a predetermined stage (for example, all stages of the battle game are ended). If the game end condition is met, the control unit 150 executes a game end process (step S106). If the game end condition is not met, the control unit 150 proceeds to the process from step S102.

[Competitive game screen]
As shown in FIG. 5, the control unit 150 displays the game score 20 obtained by the virtual user and the vitality value 21 of the virtual user by the game start process, and starts the battle game by the object appearance process. Then, the enemy characters 10a to 10d are displayed on the monitor unit 200. The control unit 150 performs an effect in which the enemy characters 10a to 10d approach the virtual user, and when the enemy characters 10a to 10d appear on the monitor unit 200 and a predetermined time elapses, the enemy character such as the enemy character 10a. And the virtual user can attack the enemy character 10a and the like.

  When the control unit 150 determines that the virtual user can attack the enemy characters 10a to 10d, the attack targets 11, 12, and 13 indicating that the enemy characters 10a and 10b can be attacked are displayed. The The control unit 150 changes the size of the attack targets 11, 12, and 13 according to the attack range against the enemy characters 10a to 10b.

  The control unit 150 displays the attack type identification displays 30a and 31a for the user to determine whether the user attacks by attacking the attack targets 11, 12, and 13 or by using a sword. ˜31c may be displayed on the monitor unit 200. That is, the attack type identification displays 30a and 31a to 31c corresponding to the attack targets 11, 12, and 13 are displayed by the control unit 150 together with the display of the attack targets 11, 12, and 13, so that the corresponding enemy characters are adopted. Inform the user of the attack type to be performed.

[Shooting decision flow processing]
Next, the shooting determination flow process executed by the control unit 150 will be described with reference to FIG. The shooting determination flow process and the sword use determination flow process, which will be described later with reference to FIG. 7, are always executed independently of the situation of the game apparatus 1 after the control unit 150 executes the game start process. The That is, the gun-type controller 500 always accepts user input to the gun-type controller 500 after the start of the battle game.

  The control unit 150 determines whether or not the trigger unit 520 of the gun-type controller 500 has received a signal indicating that a user operation has been performed (step S110). The infrared camera sensor 400 captures infrared rays emitted from the gun-type controller 500, analyzes the infrared position on the monitor unit 200 as coordinate data, and transmits the analyzed coordinate data to the control unit 150. The control unit 150 receives the coordinate data transmitted from the infrared camera sensor 400 (step S111). Here, the control unit 150 receives the coordinate data from the infrared camera sensor 400 without receiving a signal indicating that the user has performed an operation on the trigger unit 520 shown in step S110, and performs the attack determination process. May be executed.

  Next, the control unit 150 executes an attack determination process that compares the received coordinate data with the image data displayed on the monitor unit 200. For example, in an aspect in which 3D graphics is realized using a polygon, the control unit 150 compares the coordinates of the vertex of the polygon with the coordinate data transmitted by the infrared camera sensor 400 and executes an attack determination process. That is, when the coordinate data matches the coordinates of the vertexes of the polygon, the control unit 150 reduces the vitality value of the enemy character displayed in the coordinate data. Alternatively, when the control unit 150 determines that the coordinate data is close to the coordinates of the vertexes of the polygon within a predetermined range, the controller 150 displays the enemy displayed in the coordinate data based on the size of the predetermined range. The character's vitality value may be reduced (for example, if the coordinates are far from each other, the attack effect is reduced).

[Sword use decision flow]
Based on FIG. 7, the sword usage decision flow process executed by the control unit 150 will be described. The control unit 150 receives acceleration data from the gun-type controller 500 (step S120). That is, the acceleration sensor 530 detects a predetermined acceleration by a user operation, digitizes the acceleration, and transmits the acceleration value to the control unit 150 as acceleration data. The control unit 150 receives this acceleration data. Control unit 150 performs a waiting process until acceleration data is received (step S120: NO).

  When the acceleration data is received (step S120: YES), the control unit 150 determines whether the user intentionally uses the sword from the scalar value and direction of the received acceleration data (step S121). . That is, the control unit 150 compares the threshold data with the scalar value and direction of the acceleration data, and determines whether the user is intentionally using a sword.

  For example, when the control unit 150 receives acceleration data of a predetermined acceleration scalar (0.5 G or more) in a direction perpendicular to the screen of the monitor unit 200, the control unit 150 intentionally uses the sword. If it is determined that it is being performed, threshold data is set. As described above, the threshold data is data including the magnitude and direction of acceleration for determining whether the user is intentionally using a sword. In this example, the threshold data is “monitor unit 200. Screen and vertical direction "," 0.5G ". By comparing the threshold data with the detected acceleration data, the control unit executes the determination in step S121.

  When the control unit 150 determines that the user intentionally uses the sword (step S121: YES), the control unit 150 transmits the infrared camera sensor 400 that has processed the captured second electromagnetic wave. The sword coordinate data is stored in the data storage unit 190 (step S122).

  Next, the control unit 150 determines whether the trigger unit 520 has been operated (step S123). At this time, if the trigger unit 520 is operated, the process proceeds to the shooting determination flow as shown in FIG. 7 (step S123: YES). The control unit 150 performs a waiting process for a predetermined time (about 0.5 seconds) even when the trigger unit 520 is not operated (step S123: NO). That is, the control unit 150 performs a waiting process for accepting an operation from the user on the trigger unit 520 until a predetermined time has elapsed (step S124: NO).

  When the control unit 150 determines that the predetermined time has passed (step S124: YES), the sword flag serving as an identifier for determining that the user intentionally uses the sword is turned on, and The flag is stored in the RAM 170 (step S125). And the control part 150 performs an attack determination process (step S126).

  Here, steps S123 and S124 are not executed, and the trigger unit 520 is operated by the user, and at the same time, the control unit 150 executes the shooting determination flow process and determines that it is intentional use of a sword. In such a case (step S123: YES), two processes may be processed in parallel by executing step S126. That is, both the shooting determination flow process and the sword use determination flow process are executed, and the attack determination process flow described later is executed due to both processes, so that the sword is executed while executing the shooting in the battle game. It is possible to realize processing such as using

[Attack decision processing flow]
Based on FIG. 8, the attack determination processing flow executed by the control unit 150 will be described. The control unit 150 determines whether the sword flag is stored in the RAM 170 (ON) (step S130). When determining that the sword flag is stored (step S130: YES), the control unit 150 displays the sword image data on the monitor unit 200 (step S131). Then, the control unit 150 evaluates the attack effect of the sword (step S132).

  As shown in FIG. 9, the sword image data is an image as if the enemy character 10 a used by the user is cut as in the sword use image 60. The evaluation of the attack effect of the sword is determined based on the sword coordinate data detected by the second electromagnetic wave in the attack target 12, the acceleration scalar of the acceleration data, and the direction of acceleration. That is, the control unit 150 assumes that the degree of attack on the enemy character 10 is greater (the degree of decrease in the vitality value of the enemy character is greater) as the received sword coordinate data is closer to the coordinates of the center of the circle of the attack target 12. Process.

  Furthermore, if the received acceleration scalar is large, the control unit 150 has a large degree of attack against the enemy character 10 (the degree to which the vital character value of the enemy character is decreased is large). Here, the control unit 150 extracts only the vector component (hereinafter, “screen vertical direction”) in the vertical direction with respect to the screen of the monitor unit 200 from the acceleration direction vector of the received acceleration data. The vertical direction is the acceleration scalar.

  On the other hand, when determining that the sword flag is not stored in the RAM 170 (step S130: NO), the control unit 150 displays the shooting image data on the monitor unit 200 (step S133). And the control part 150 evaluates the attack effect of a shooting (step S134).

  As shown in FIG. 9, the shooting image data 65 is image data in which the enemy character 10b is attacked by shooting. And the control part 150 performs the evaluation process of the attack effect of a shooting. The control unit 150 compares the coordinate data received from the infrared camera sensor 400 with the position of the attack target 12 displayed on the monitor unit 200, and executes an attack effect evaluation process. In other words, the control unit 150 processes that the degree of attack on the enemy character 10 is greater (the degree of decrease in the vitality value of the enemy character is greater) as the received coordinate data is closer to the coordinates of the center of the circle of the attack target 12. To do.

  Then, the control unit 150 turns off the sword flag (deletes the sword flag stored in the RAM 170) (step S135), and ends the attack determination processing flow.

  Next, a description will be given of a process in which the control unit 150 determines that the sword is intentionally used when the user performs the operation of swinging down the gun-type controller 500 and evaluates the attack effect by using the sword. FIG. 10 shows the locus 50 of the electromagnetic wave when the user performs an action of swinging the gun-type controller 500 from the upper side to the lower side of the monitor unit 200 (hereinafter referred to as a “lowering action”) with respect to the enemy character 10a. The control unit 150 may determine in step S <b> 121 to determine that the sword is intentionally used when the acceleration data by the swing-down operation is received from the acceleration sensor 530.

  Since the gun-type controller 500 constantly irradiates the first electromagnetic wave, the infrared camera sensor 400 images the locus of the electromagnetic wave irradiating the monitor unit 200. The infrared camera sensor 400 captures the trajectory and transmits it as a straight (or curved) trajectory in which a plurality of sword use coordinate data are collected. The infrared camera sensor 400 may transmit a plurality of sword coordinate data to the control unit 150. When the locus is a straight line, the infrared camera sensor 400 transmits the start point coordinates and the end point coordinates of the locus to the control unit 150. It's okay. The control unit 150 that has received the sword coordinate data in this way executes the attack determination processing flow, compares a plurality of sword use coordinate data or straight line start point coordinates and end point coordinates, and the attack target 12 coordinates, Perform an attack effectiveness assessment.
