[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game method, a game program, a game device and a game system for playing a game in which a player operates an operation article to hit a virtual projectile on a virtual target in a game space.

[0002]

2. Description of the Related Art In order to give a simulated experience of a player actually handling a gun, a bow and arrow in a game, a game device using an operation object imitating a gun or a bow is generally known. ing. For example, Japanese Unexamined Patent Publication No. 2000-189670 provides an operation article having a bow-shaped grip portion, a string spanning the grip portion, and a tension sensor that detects tension applied to the string. There is disclosed a game device in which the flight distance of an arrow displayed on the screen changes depending on how the strings are pulled. According to this game device, the player can hit the arrow to a virtual target near or far by adjusting the flight distance of the arrow according to the pulling degree of the string, and therefore the player actually shoots the arrow. It is possible to get a pseudo-experience.

[0003]

However, in the above game device, one target is shot down by one shot of an arrow, and a plurality of virtual targets are skewered at one time.
It is not possible to increase the power of the arrow by maintaining the force applied to the strings by the player for a certain period of time, and to damage multiple virtual targets collectively. Furthermore, when the player is attacked by the enemy, he or she cannot experience the damage.

[0004] It is an object of the present invention to provide a technique that allows a user to experience a game that makes the most of the characteristics of an elastic body by using an operation article that is constructed using the elastic body.

[0005]

In order to solve the above-mentioned problems, the first invention of the present application provides a game space displayed on a display by a player operating an operation article having an elastic body in a real space. A game method for shooting a virtual projectile and applying the virtual projectile to a virtual target in the game space is provided. This method has the following steps.

A: a stress detecting step of detecting a stress generated in the elastic body as a result of the player operating the operation article, B: an aiming position detecting step of detecting an aiming position of the operation article on the display, C : A stress acquisition step of acquiring the detected stress,
Aiming position acquisition step of acquiring the detected aiming position on the display, D: Aiming position determining step of determining an aiming position in the game space based on the acquired aiming position on the display, E: the Power determination step of determining the power of the virtual projectile from the acquired stress, F: Player position detection step of detecting the position of the player in the real space, and G: Position of the player in the real space. A trajectory that determines the player position in the game space from the above, and determines the trajectory of the virtual projectile in the game space based on the player position in the game space, the aiming position in the game space, and the power. Determining step, H: a hit determining step of determining whether or not the virtual projectile hits a virtual target based on the trajectory, and I: the above If virtual projectile has hit the virtual target, a display control step of displaying the effect according to the power of the virtual projectile on the display.

The operation article is an input device operated by the player to progress the game, and is formed in a shape similar to a bow, a gun, a slingshot, or the like. The virtual operation object is a game character for expressing the operation object in the game space,
It is represented by the same shape as the operation article. The virtual projectile represents, for example, an arrow when the operation article is formed in a bow shape, a bullet when the operation article is formed in a gun shape, and a pachinko ball when the operation article is formed in a pachinko shape. It is a game character. The virtual target is, for example, a game character that represents a target or an enemy.

The elastic body is, for example, a bow-shaped operation article having a string, and when the player pulls the string, a spring which accumulates elastic force in association with the above-mentioned operation can be used. The stress can be detected using a tensiometer, a microswitch, an optical sensor, a potentiometer, an acceleration sensor, an ultrasonic sensor, or any other element. The aiming position can be detected by using, for example, a known photo sensor.

The player position detecting step includes, for example, an infrared sensor and an ultrasonic sensor for emitting infrared rays and ultrasonic waves to the player and receiving the reflections thereof, as well as holding or putting on an operation article such as an operation object. It can be performed by using a CCD camera that detects light emitted from a light emitting element provided on the object. Since the trajectory of the virtual projectile is determined by the position of the player, the player can aim the same virtual target from various positions and angles by changing the position. Therefore, the player can have a simulated experience as if he is attacking the virtual target while changing the place. To determine the trajectory of the virtual projectile in the game space based on the aiming position and power in the game space, for example, if the power is smaller than a certain value F, the lower left corner of the screen is the starting point and the aiming position is the end point. It is conceivable that a gentle parabola is determined as the trajectory of the virtual projectile, and if the power is greater than a certain value F, the trajectory of the virtual projectile is determined as a substantially linear parabola whose starting point is the lower left of the screen and the aiming point is the end point. To be

Displaying the effect according to the power of the virtual projectile means displaying a state in which the virtual target suffers great damage when the virtual projectile having a great power hits the virtual target. For example, when the player strongly pulls and releases the string of the bow-shaped operation object having the above-mentioned string (hereinafter, simply referred to as the bow-shaped operation object), the power of the virtual projectile is increased, and the damage given to the virtual target is increased. To be large.

In a second invention of the present application, in the first invention, J: a virtual projectile displaying step for displaying the virtual projectile moving along the trajectory, and K: a case where the virtual projectile hits a virtual target. , A power subtraction step of reducing the power, L: a penetration determination step of determining whether or not the virtual projectile has penetrated a virtual target hit by the virtual projectile, M: the virtual projectile on the virtual target A penetration display step for displaying a penetrated state, and N: a repeating step of repeating the hit determination step, the power subtraction step, the penetration determination step, and the penetration display step until the power becomes zero or less. Further, in the display control step, a penetration effect which is an effect on a virtual target penetrated by the virtual projectile is further displayed on the display. Provide a game method.

The determination as to whether or not the object has penetrated can be exemplified by determining that the material has penetrated when the power is larger than the parameter "hardness" of the virtual target. Displaying the penetration effect means, for example, displaying a state in which a virtual target that has penetrated the virtual projectile is destroyed. When it is determined that the hit determination step is successful, the power of the virtual projectile is reduced. If the power remains even after hitting a virtual target with a virtual target, you can hit the virtual projectile with another virtual target. For example, when there are multiple virtual targets on the trajectory of the virtual projectile, the player can collectively shoot through the multiple virtual targets with one virtual projectile by applying a strong force to the operation object. It will be more interesting.

The third invention of the present application is the first invention or the second invention.
In the invention, O: a holding time detecting step of detecting a holding time which is a time during which the stress is held in a substantially constant state, and P: the power of the virtual projectile is increased according to the detected holding time. A game method further including a special power determination step.

When the player applies a certain force to the elastic body and maintains this state for a certain time or longer, the virtual projectile can be given special power. For example, when the player performs a motion of releasing an arrow after maintaining the state where the bow of the bow-shaped operation object is constantly stretched for 5 seconds, it exists not only around the virtual target hit by the virtual projectile but also around the virtual target. Other virtual targets are also destroyed.

Fired at the target. The player can change the position of the virtual player in the game space by moving within a predetermined area on the front surface of the game device 100. This allows the player to launch a virtual projectile from various positions within the game space.
The game is cleared by defeating a predetermined number and types of virtual targets. The game is over when the remaining life of the player becomes zero.

(3-1-1) Relationship between Strength of Elastic Force Stored in Spring of Arched Object and Holding Time and Power of Virtual Projectile The power of the virtual projectile is equal to that of the elastic force stored in the spring 205. It changes depending on the strength. FIG. 7A is a diagram showing a state where the player pulls the arrow weakly. FIG. 7B shows an example of the power of the virtual projectile when the player pulls the arrow weakly as shown in FIG. 7C. FIG. 7C is a diagram showing a state in which the player has strongly pulled the arrow. FIG. 7D shows an example of the power of the virtual projectile when the player strongly draws the arrow as shown in FIG. 7C.

When the player weakly pulls the arrow 204 as shown in FIG. 7A, the elastic force stored in the spring 205 is small, and as shown in FIG. 7C, the player strongly pulls the arrow 204. For example, the elastic force stored in the spring 205 increases. The value of this elastic force is stored in the RAM 19 every predetermined time.
Memorized in. If the maximum value of the elastic force memorized between the time when the elastic force becomes zero and the time when the elastic force becomes zero next time is large, the power of the virtual projectile becomes large, and conversely, if it is small, the power of the virtual projectile becomes small It is determined. For example, the power is such that if the player pulls the arrow 204 weakly, the virtual projectile will only penetrate one virtual target (see FIG. 7B), but if the player pulls strongly, it can shoot out multiple virtual targets (FIG. 7).
(See (d)). When a virtual projectile hits a virtual target, its power decreases, and the virtual projectile continues to fly until its power reaches zero.

When the player holds the arrow 204 at the same position for a certain period of time or longer, it is possible to give the virtual projectile special power (hereinafter referred to as a special move). For example, when the elastic force is kept constant for a predetermined time, for example, 5 seconds or longer, lightning strikes the place where the virtual projectile has landed and all virtual targets around the landing point are destroyed as shown in FIG. be able to. The power of the Special Move may be changed depending on the value of the held elastic force and the holding time.

(3-1-2) Relationship between Position and Aiming Position of Player and Orbit of Virtual Projectile The trajectory of the virtual projectile is the position of the player in the game space and the aim of the virtual projectile in the game space. It is calculated as a straight line or a curve that passes through the position. The position of the player in the game space is determined based on the position of the player in the real space detected by the position detection unit 6. FIG. 9A is a schematic plan view of the battle game system 2000 seen from above. One player moves in areas A and B to play the game, and another player moves in areas C and D to play the game. FIG. 9B is a diagram showing player positions A ′ and B ′ in the game space. Regions A and B in the real space are player positions A ′ in the game space, respectively.
And B '.

The position sensors 102a and 102b are respectively shown in FIG.
The players existing in the areas A and B of (a) can be detected, and the position sensors 102c and 102d can detect the players existing in the areas C and D, respectively. When the game is started by one player, the position sensors 102a and 102b are used.
Infrared rays are emitted from 02a and 02b. Position sensor 102
When the infrared ray reflected by a hits the player is detected, the position of the player in the real space is the area A in FIG.
The player position in the game space is determined as A'in FIG. 9 (b). Similarly, when the position sensor 102b detects the body temperature of the player, the position of the player in the real space is determined to be the area B, and the position of the player in the game space is determined to be B'in FIG. 9B.

When the game is started by two players, the position sensors 102a to 102d are used. When the game is started by two players, the position sensors 102c and 102d may similarly detect the position of the other player. Furthermore, if more detailed player position detection is desired, the number of position sensors 102 installed may be increased.

The aiming position in the game space of the virtual projectile is obtained by detecting the horizontal bright line at the timing when the elastic force detected by the force sensor 206 becomes zero and calculating the horizontal and vertical bright line positions at this timing. Obtained from the aiming position on the monitor. Therefore, the player can attack the virtual target from different points in the game space by changing the position in the real space. For example, when the player moves from the area A to the area B in the real space, the virtual projectile can be launched from the game space position B ′ where the trajectory of the virtual projectile released by the player intersects with the plurality of virtual targets. FIG. 10 is an explanatory diagram showing that the firing point of the virtual projectile changes according to the change in the position of the player in the real space. FIG. 10A is a diagram showing a state in which, in the game space shown in FIG. 9B, a virtual projectile is shot from the player position B ′ in the game space with the aiming at the virtual target Z1. In this figure, virtual target Z1 and virtual target Z1
The virtual targets Z2 and Z3 behind it have been shot through. FIG. 10B is a diagram showing a state where a virtual projectile is shot from the player position A ′ to the virtual target Z3 in the game space shown in FIG. 9B.

(3-2) Process Performed by CPU The process performed by the CPU 10 will be described with reference to FIG. 1 again.
The CPU 10 includes an air vibration control unit 11 and a firing control unit 1.
3, a hit determination means 14, a sound output control means 15, an operation determination means 16, a situation determination means 17, an object display control means 18, and a player position determination means 19.

The operation determining means 16 acquires the aiming position on the monitor from the aiming position detecting section 52 at a constant time interval ΔT1, and determines the corresponding aiming position in the game space R
It is temporarily stored in AM19. Further, the operation determination means 16 is
The value of the elastic force of the spring 205 of the bow-shaped operation article 200 is acquired at a constant time interval ΔT1 and stored in the RAM 19. further,
The operation determining means 16 stores in the RAM 19 the maintenance time, which is the time when the elastic force is maintained constant.

The player position determining means 19 acquires the position of the player in the real space detected by the position detecting section 6 at a constant time interval ΔT1, determines the player position in the game space, and stores it in the RAM 19. FIG. 17 shows the RAM1
9 is a conceptual explanatory diagram of a work table 191 created in FIG. This table stores the aiming position in the game space, the player position in the game space, and the elastic force at each time.

The firing control means 13 determines whether or not a virtual projectile has been fired. If fired, it determines the trajectory of the virtual projectile. This trajectory is calculated based on the elastic force value stored in the work table 191, the aiming position in the game space, and the player position in the game space. Orbit
It may be a straight line or a curved line such as a parabola that starts from the player position in the game space and passes through the aiming position in the game space. The end point of the trajectory may be a position corresponding to the end of the game space.

The hit determination means 14 determines whether or not the launched virtual projectile hits n virtual targets E (n is a natural number) or walls existing in the game space. In particular,
The hit determination means 14 determines whether or not the position of the virtual target and the position of the virtual projectile match while moving the virtual projectile along the trajectory determined by the launch control means 13, and the two match. If it does, it is judged to have been hit. And
The result of the above judgment is stored in the RAM 19. Then, the result of the above judgment is stored in the RAM 19. Further, the hit determination means 14 reduces the power in the case of a hit by a predetermined value, and repeats the above determination until the power becomes zero. on the other hand,
The hit determination means 14 determines whether or not an enemy projectile fired by the virtual target at the player has hit the player. Specifically, when the trajectory of the enemy projectile in the game space matches the player position in the game space, it is determined that the player has been hit by the enemy.

When the player is hit by an enemy, the air vibration control means 11 controls the air vibration section 7 to generate air vibration. The sound output control means 15 causes the speaker to output the sound effect data read from the semiconductor memory 4 to the RAM 19 according to the result of the hit determination. The sound effect may be, for example, a sound in which a virtual projectile hits a virtual target and the virtual target is destroyed.

The situation determining means 17 calculates the remaining life of the player according to the result of the hit determination. For example, when the player is hit by an enemy projectile as a result of the hit determination, the life of the player is reduced by a predetermined degree accordingly. The player's life is stored in the RAM 19 (not shown). On the other hand, the situation determination means 17 has a RAM 19
The power of the virtual projectile is determined according to the value of the elastic force stored in the RAM 19 and stored in the RAM 19. The power is determined based on the maximum value until the elastic force increases from zero and becomes zero again. Further, the situation determination means 17 sets the deadly attack flag bH = 1 when the maintenance time stored in the RAM 19 is a predetermined time or more. The elastic force has a predetermined value, for example, the spring 205
Is the maximum value of the elastic force that can be stored, and when the maintenance time is a predetermined time or more, the special move flag bH = 1
Also good. When the special move flag bH = 1, the power is set to the special move oversize value, and the effective range that is a range in which the virtual target can be destroyed by the special move is set. Furthermore, the situation determination means 17 determines y virtual targets H that the hit determination means 14 has determined have hit a virtual projectile.
(Y ≦ n, y is a natural number) or the destruction flags of z virtual targets H ′ (z ≦ n, z is a natural number) existing in the above-described effective range are set to 1. In addition, the situation determination means 17 determines whether the virtual projectile hitting the virtual target has penetrated the virtual target. Specifically, if the “hardness” of the virtual target H is greater than or equal to the power, it is determined that the virtual projectile has penetrated the virtual target. Here, "hardness" is a parameter indicating the resistance of the virtual target to the virtual projectile. Furthermore, the situation determination means 17 determines w virtual targets P (w ≦
The value of the penetration flag is 1 for y and w are natural numbers.

This allows the player to instantly feel the air vibration and feel the damage. <Other Embodiments> (A) Other Examples of Position Detecting Unit As another example of the position detecting unit 6 shown in FIG. 1, an ultrasonic sensor can be cited. This ultrasonic sensor is composed of a transmitting element provided in the center of the upper part of the housing and a pair of receiving elements provided on the left and right of the upper part of the housing. The method of detecting the position of the player by the ultrasonic sensor is performed as follows. Ultrasonic waves are emitted from the central transmitting element, and the ultrasonic waves reflected by hitting the player's head are received by the left and right receiving elements. Then, the position of the player in the real space is determined by calculating the distances from the left and right receiving elements to the head. This method is generally known as triangulation. The player position determining means 19 determines the player position in the game space according to the position of the player thus determined in the real space.

(B) It is also possible to increase the power of the special move according to the stress of the elastic body maintained for a certain period of time. For example, the effective range is wider when the elastic force of the spring 205 of the bow-shaped operation article 200 in the first embodiment is maintained at 100 N for 5 seconds than when the elastic force of the spring 205 is maintained at 90 N for 5 seconds. In this way, if the maintained elastic force is large, the effective range of the special move can be expanded, and the player can change the power of the special move by his / her operation.

(C) It is also possible to increase the power of the special move according to the maintenance time. For example, the longer the maintenance time, the wider the effective range of the special move. By doing so, the player can change the power of the special move by his / her operation. (D) The present invention also includes a computer-readable recording medium recording a program for performing the above-described processing. Here, as the recording medium, a computer-readable flexible disk, semiconductor memory, CD-ROM, DV
