Then, the aim 120 is aligned with the enemy 110 appearing on the game screen 100, and the trigger button 22 is operated to shoot down the enemy plane and raise the score. Game screen 100
The remaining game time 130 is displayed in the upper corner.

FIG. 3 is a functional block diagram of the commercial video game apparatus of the embodiment.

The commercial video game device 10 of the embodiment is
The control device 40, the I / O controller 42, the operation amount correction calculation unit 44, the game calculation unit 46, and the display circuit 50.
And a display 30.

The control device 40 is a member operated by the player, such as various levers 14 and 16 and operation buttons 20 and 22 shown in FIG. In particular, the control lever 14 is provided with an x-direction volume that outputs the amount of tilt in the left-right direction as a volume value Vx and a y-direction volume that outputs the amount of tilt in the front-rear direction as a volume value Vy. Each volume value Vx, Vy is I as the manipulated variable
It is configured to be output to the / O controller.

Similarly, the speed lever 16 is also provided with a z-direction potentiometer for outputting the operation amount in the front-rear direction as a volume value Vz, and the output Vz is I.
It is configured to output to the / O controller 42.

As described above, in the control device 40 of the embodiment, the left and right and up and down turning amounts of the airplane operated by the player are output as Vx and Vy, and the forward speed is output as Vz.

Then, the manipulated variable correction calculator 44 performs a predetermined correction calculation process on each of the manipulated variables Vx, Vy, Vz thus input, as described later, to obtain the correction calculation data ω.
It outputs x, ωy, and αz to the game calculation unit 46.

The game calculation unit 46 performs various game calculations based on the input signal from the control device 40 and a predetermined game program, and uses the display circuit 50 to display on the display 30 as shown in FIG. Game screen 100
Is displayed. Here, the game calculation unit 46
Is formed so that an airplane moves in a predetermined three-dimensional game space by a player's control, and the view in the three-dimensional game space seen from the cockpit of the airplane is perspectively projected and converted onto a predetermined projection plane. The game screen 100 is created and is displayed on the display 30.

FIG. 4 shows the principle of such an image synthesizing method.

The game device of the embodiment stores in advance information about the three-dimensional game space 300 and the three-dimensional object 110 appearing in the three-dimensional game space 300. The image information regarding the three-dimensional object 110 includes a plurality of polygons 112-1, 112-2, 112-.
It is expressed as a shape model consisting of a combination of 3 ... And is stored in advance in the memory.

Taking the game of the embodiment as an example, the three-dimensional object 110 is an enemy plane appearing in the three-dimensional game space 300, and in the three-dimensional game space 300,
Besides, as shown in FIG. 6, various types of 3 representing the scenery on the ground, etc.
A dimensional object is placed.

FIG. 5 shows an airplane 130 operated by a player in the three-dimensional game space 300 and an enemy airplane 1.
The positional relationship with 10 is shown. In the figure, the viewpoint 210 shown in FIG. 4 is set at the position of the cockpit of the airplane 130 operated by the player. Moreover,
A viewpoint coordinate system in which the direction of the line of sight of the viewpoint 210 is defined as the z axis, the horizontal direction as the x axis, and the vertical direction as the y axis is also set. This viewpoint coordinate system moves as the own device 130 moves.

Then, as shown in FIG. 4, the three-dimensional object 110 and the other three-dimensional objects in the three-dimensional game space 300 are perspective-projected on the projection plane 310 of the viewpoint coordinate system to form a pseudo three-dimensional image 320. It is displayed on the display 30.

When the computer blafix method is used, the shape model of the three-dimensional object 110 is created using an independent body coordinate system. That is, each polygon that forms the three-dimensional object 110 is arranged on this body coordinate system, and its shape model is specified. Furthermore, the three-dimensional game space 300 is configured by using the world coordinate system, and the three-dimensional object 110 represented by using the body coordinate system is arranged in the world coordinate system according to its motion model. And
With the position of the viewpoint 210 as the origin, the data is converted into a viewpoint coordinate system in which the viewpoint direction is the positive direction of the z-axis, and the projection plane 3
Each coordinate is perspective-projected into a screen coordinate system of 10. In this way, the image within the field of view of the three-dimensional game space 300 that can be seen from the cockpit of the player's own aircraft 310 operated by the player can be displayed on the display 30.

Therefore, on the display 30, the view of the front of the airplane operated by the player from the cockpit is displayed as the game screen 100, and the player 200 actually operates the airplane. You can perform the maneuver as if you were sitting.

By the way, in such a video game device, the enemy plane 110 is moved in the three-dimensional game space 300 in three spaces.
Move freely in three dimensions. Therefore, the enemy 110 does not always exist in the player's visual field. In particular, as in the present embodiment, in the case where the own airplane 130 is formed so that it can be freely maneuvered up, down, left and right in the three-dimensional game space, this can be easily done once the enemy airplane 110 is lost from the view. It is easy to fall into the situation where it cannot be captured by. This tendency is particularly noticeable when the enemy's plane flies in a complicated manner.

A feature of the present invention is to assist the control of the player's own machine 130 by the control device 40 so that the player can easily track the target 110 in the three-dimensional game space 300.
Thereby, for example, even when a game such as an airplane that is difficult to control is to be played, an enemy moving in the three-dimensional game space can be easily caught and the game can be enjoyed.

That is, in the commercial video game apparatus of the embodiment, the enemy plane 110 is in the three-dimensional game space 300.
Fly freely inside. The player uses the control device 40 to control his / her own airplane 130 and track the enemy airplane 110 moving in three dimensions. And enemy plane 11
When 0 enters the front field of view of the player's aircraft 130, the game screen 110 in which the enemy airplane 110 is seen in front is displayed on the display 30, as shown in FIG. The player aligns the sight 120 with the displayed enemy 110 and operates the trigger button to shoot down the enemy and raise the score.

However, since the enemy airplane 110 flies while moving three-dimensionally, even if the enemy airplane 110 is caught in the game screen, the enemy airplane 110 can easily escape from the game screen. Many. In particular, a player unfamiliar with the game operation, if the enemy's airplane 110 moves even a little, operates the operation lever 14 too much and swivels in the vertical and horizontal directions more than necessary, causing the enemy to enter the game screen 100. It is difficult to keep capturing. Further, once the enemy airplane 110 is escaped from the screen, it takes too much time to control the aircraft 130 in that direction even if the position of the enemy is found using a radar device or the like (not shown). There is.

As described above, there are three players who are unfamiliar with the operation.
An enemy plane that flies while moving within the three-dimensional game space 1
It is difficult to capture 10 and display it on the display 30. Therefore, for example, within the game time of 3 minutes or 5 minutes, the enemy airplane 11 is displayed on the display.
The time for capturing 0 becomes extremely short, and the game is often over before the game is enjoyed.

Therefore, in the game device of the embodiment, the operation signal input from the control device 40 is corrected in the operation amount shown in FIG. 3 so that the enemy plane 110 can be easily caught in the display display area of the viewpoint coordinate system. It is configured to be corrected by the calculation unit 44 and input to the game calculation unit 46.

First, when the game is started and the player controls the player's own machine using the control device 40, the following operation signals cause the I / O controller 42 to respond to the operation of the control lever 14 and the speed lever 16. It is input to the operation amount correction calculation unit 40 via the.

The left and right volume values of the control lever 14; Vx front and rear volume values of the control lever 14; Vy, the volume value of the speed lever 16; Vz, the operation amount correction calculation unit 44, the operation amounts Vx, Vy, thus input. Vz is 1 / one frame scanning unit
Read every 60 seconds.

If the airplane is moved using the read operation amounts as they are, the above-mentioned problems occur.

The manipulated variable correction calculator 44 of the embodiment performs the following correction calculation on the input values Vx, Vy and Vz, and inputs them to the game calculator 46.

[0044]     Rotational speed of the machine 130 in the x direction ωx = iVx     Rotational speed of y-direction of own machine ωy = jVy     Z acceleration in the z direction of the aircraft 130 αz = kVz (1) Here, i, j, and k are response characteristic coefficients.

Depending on how these response characteristic coefficients are set, it is possible to carry out an appropriate correction calculation according to various game contents.

Below, the current position of the enemy airplane 110 is set to P
= (X, y, z), a specific example of performing the correction calculation based on the current position will be described.

As shown in FIG. 5, the cockpit of the airplane 130 operated by the player is taken as the origin of the viewpoint coordinate system, and the current position of the enemy airplane 110 in this viewpoint coordinate system is P =
(X, y, z).

At this time, as shown in FIGS. 8A and 8B, in the zx plane and the zy plane in the viewpoint coordinate system, the x-direction angular position of the enemy airplane 110 with respect to the aircraft 130 is θx, y-direction angle. When the position is θ y and the z coordinate position of the enemy airplane 110 is Z, the response characteristic coefficient can be expressed by the following function.

I = fx (θx) j = fy (θy) k = fz (Z) (2) Here, the x-direction angular position θx and the y-direction angular position θy are respectively expressed by the following equations.

Θx = tan ⁻¹ (x / z) θy = tan ⁻¹ (y / z) (3) Various modes of correction can be performed according to the setting method of each function of the equation (2). The following formula is used in the examples.

[0051]     i = fx (θx) = i0 + lθx     j = fy (θy) = j0 + mθy     k = fz (Z) = k0 + nz (4) However, i0, j0, k0, l, m, n are constants.

Then, i, j and k obtained by the equation 4 are substituted into the above equation 1 to obtain ωx, ωy and αz.

The operation amount correction calculation unit 44 of the embodiment repeats such correction calculation every 1/60 seconds which is one frame unit according to the flow shown in FIG.

That is, in step S1, each lever 1
Input values Vx, Vy, and Vz of 4, 16 are read.

Next, in a step S2, the game calculation section 46
The three-dimensional coordinates of the current position of the enemy aircraft 110 in the viewpoint coordinate system are calculated as P = (x, y,
z).

Then, in step S3, based on the input position data P = (x, y, z) of the enemy aircraft, each of the above-mentioned mathematical expressions 2, 3 and 4 is performed, and the response characteristic coefficient i,
Find j and k.

Then, in step S4, the equation 1 is calculated based on the response characteristic coefficients thus obtained and the input values of the operating levers, and the corrected x-direction rotational speed ωx, y is corrected. The direction rotation speed ω y and the z-direction straight acceleration α z are calculated and output to the game calculation unit 46.

As a result, even if the control lever 14 is operated in the x and y directions by the same amount, the angular position θx, shown in FIG.
When θy is small (the closer the enemy's position is to the center of the display 30), the correction amounts are calculated so that the manipulated variables Vx and Vy act smaller. On the contrary, θx, θy
Is larger (the enemy's position is farther from the player's visual field range), the correction calculation is performed so that the values of Vx and Vy act more greatly.

Further, by performing the correction calculation operation in the z direction, the player's control is assisted so that the enemy plane 110 is always positioned in front of the own plane.

As described above, in the video game device of the embodiment, the player temporarily sets the enemy plane 110 to the game screen 1
When it is caught within 00, correction calculation is performed so that the movement amount of the own machine 130 becomes small even if the control lever 14 is operated too much. For this reason, the player's control is assisted so that the once caught enemy can be easily tracked without being missed. Further, even when the enemy plane 110 moves up, down, left, and right in the game space, the lever operation amount is corrected and calculated in a direction in which the enemy plane 110 can be easily captured, so that the aim 120 can be easily adjusted to the moving enemy plane 110. You can shoot down.

When the enemy caught in the game screen 100 is located at a distant position, the speed lever 16 is operated to increase the speed of the player's machine and reduce the distance from the enemy machine.
In this case, if the speed is increased too much and it is about to pass the enemy aircraft 110, the Vz value is corrected and calculated as described above, and the speed is reduced.
The player's control can be assisted so that the enemy does not escape to the outside of the game screen 100.

When the enemy plane 110 is outside the game screen 100, the operation amount of each lever 14, 16 is corrected so that the enemy plane 110 is within the display area. The enemy aircraft 110 can be easily caught.

In this way, according to the business video game apparatus of the embodiment, it is possible to assist the control of the player so that the enemy plane 110 moving around in three dimensions always enters the game screen 100. Therefore, even within a limited game time such as an arcade game machine, the ratio of the time when the enemy machine appears in the game screen 100 is increased, and the enjoyment and fun of the game content can be enjoyed accordingly. Therefore, it is possible to obtain a professional-use video game device that even a beginner can fully enjoy.

In this embodiment, the speed lever 16
Although the correction calculation is performed based on the operation amount Vz from, the correction calculation in the z direction may not be performed if necessary, and only the correction calculation for the operation amount of the control lever 14 may be performed. . Further, since the control using the control lever 14 is particularly difficult in the horizontal direction (x-axis direction), the control amount V
The correction of y may not be performed, and only Vx may be the correction target.

Further, in the above equation 4, θx, θy, Z
Instead of (θx −θa), (θy −θb), (Z−
C), i = i0 + l ([theta] x- [theta] a) j = j0 + m ([theta] y- [theta] b) k = k0 + n (Z-C) (4 '), which is different from the line-of-sight direction ([theta] a, Z in the direction of θb)
It becomes easy to catch the target at the position of the axial distance C. In particular, setting C to the front is important in a shooting game.

Here, by setting θa and θb in the direction of the aim 120 in the viewpoint coordinate system, the player's control can be assisted so that the enemy 110 can be easily caught by the aim 120.

In addition, in each of the above-mentioned embodiments, the enemy 1
Although a case has been described as an example in which the operation is assisted so that the player can easily capture the enemy 10, the present invention is not limited to this, and the enemy 110 can be captured within a predetermined display range centered on the viewpoint direction or the sighting 120 direction in the display 30. It may be configured to assist the maneuver so that it can be easily received. In this case, i, j, and k may be obtained as shown in the following equation (see FIG. 8).

First, i is calculated by the following equation.

[0069]   When θx> θa1 i = i0 +1 (θx −θa1)   When θa2 ≤ θx ≤ θa1 i = i0   When θx <θa2 i = i0 + 1 (θx −θa2) (4-1 ′) Further, j is calculated by the following equation.

[0070]   When θy> θb1 j = j0 + m (θy −θb1)   When θb2 ≤ θy ≤ θb1 j = j0   When θ <θb2: j = j0 + m (θy−θb2) (4-2 ') Further, k is calculated by the following equation.

When Z> C1 k = k0 + n (Z-C1) When C2≤Z≤C1 k = k0 When Z <C2 k = k0 + n (Z-C2) (4-3 ') By doing so, as shown in FIG.
It becomes easier to capture the right and left from the line-of-sight direction within a range having a width of θa1 and θa2. Furthermore, the enemy 110 is moved up and down by θb.
It becomes easier to capture within a range with a width of 1 and θb2. Further, it becomes easy to catch the enemy 110 in the line-of-sight direction (Z-axis direction) within a range having a width of C1 to C2.

Therefore, for example, the above-mentioned θa1, θa2, θb1, θ
b2 is set in accordance with the lock-on area of the aim 120, and C1 to C2 are set in an appropriate range of the shootable distance so that the enemy 110 can be easily caught in the lock-on area of the game screen 100 and fired. The player's control can be assisted. In this case, the maneuvering assistance is released after the vehicle is caught in the lock-on area.

Therefore, using such a method, for example, the game stage is divided into a beginner stage, an intermediate stage, and an advanced stage. At the beginner stage, the correction arithmetic expression of the above formula 4 or formula 4'is used to determine the viewpoint direction or aiming. The operation amount Vx of the control device so that the enemy 110 can be easily caught in 120 directions
, Vy, Vz are corrected, and in the intermediate stage, the numbers 4-1 ′, 4-2 ′, and 4-3 ′ are used to easily catch the enemy 110 in a predetermined lock-on area in the game screen 100. The operation amounts Vx, Vy, Vz are corrected and calculated, and after the lock-on area is captured, the correction calculation is canceled. In the advanced stage, the enemy 110 is simply displayed until it enters the game screen 100. Number 4-1 'to 4-
The correction calculation using 3'is performed, and after the correction calculation is captured on the game screen, the correction calculation may be canceled. As a result, it is possible to assist the operation according to the level of the player.

Other Embodiments In the above embodiments, the case where the input data Vx, Vy, Vz from the control device 40 are corrected and calculated based on the current position of the enemy aircraft 110 has been described as an example, but the present invention is not limited to this. The present invention is not limited to this, and the present position and moving direction of the enemy aircraft 110 may be used as the target data, and the correction calculation may be performed based on this target data.

FIG. 9 shows an example of the case where such a correction calculation is performed.

When performing the correction calculation of the embodiment, FIG.
As shown in (A) and (B), the angular positions θx and θy of the enemy aircraft 110 in the x and y directions are obtained in the same manner as in the above embodiment.

Further, as shown in FIGS.
The advancing angles ψx and ψy of the enemy aircraft 110 in the z-axis direction and the velocity component vz in the z-axis direction in the zx and zy planes are obtained.

Then, the values thus obtained are substituted into the following equations to calculate the response characteristic coefficients i, j, k.

I = gx (θx, ψx) = i0 + l (θx + ψx) j = gy (θy, ψy) = j0 + m (θy + ψy) k = gz (θz, vz) = k0 + n (Z + t0 · vz) ... (5) Then, by substituting the response characteristic coefficient obtained in this way into the equation 1, the rotational angular velocities ωx, ωy, and the linear acceleration αz in the z direction of the aircraft 130 are calculated.
Can be calculated for correction.

As described above, by using not only the current position of the enemy aircraft 110 but also the moving direction thereof as the target data for correction, even when the enemy aircraft 110 tries to escape from the game screen, The player's control can be assisted so that tracking can be performed easily.

In addition to this, the future position of the enemy plane 110 moving in the three-dimensional game space is predicted, and this enemy plane 1
It can also be configured to assist the player in maneuvering so that he can track 10.

For example, an airplane 130 operated by a player
Local coordinate system (viewpoint coordinate system) centered on the current position of
At a predetermined short time Δt seconds (1 frame unit
/ 60) the enemy's future position is P '= (x', y '
, Z ′), the response characteristic coefficients i, j, k may be calculated by using this future position according to the following equation.

I = hx (θx ′) = i0 + l ′ θx ′ j = hy (θy ′) = j0 + m ′ θy ′ k = hz (z ′) = k0 + n ′ Z ′ (6) Here, θx ′ and θy ′ are represented by the following equations.

Θx ′ = tan ⁻¹ (x ′ / z ′) θy ′ = tan ⁻¹ (y ′ / z ′) (7) In this way, the player's control is assisted based on the future position of the enemy aircraft. By doing so, the enemy plane 110 is displayed in the game screen 100.
It is possible to assist the control of the player so as to make it easier to catch.

Here, the method of obtaining the coordinates of the future position P ′ of the enemy 110 is to set the world coordinate position (X ′, Y ′, Z ′) of the enemy after Δt seconds with the current position of the own aircraft 130 as the center. The viewpoint coordinate system (x ′, y ′, z ′) to be converted is obtained.

It is also possible that the position (X ′, Y ′, Z ′) of the enemy aircraft 110 after Δt seconds in the world coordinate system is given in advance as an operation table. In this case, the world coordinate position of the enemy aircraft after Δt seconds may be read from the operation table and converted into the viewpoint coordinate system.

Besides this, the current position (X, Y, Z) and the moving speed (ωx, ωy in the world coordinate system are also used.
, Vz), the future position of the enemy aircraft 110 in the viewpoint coordinate system can be calculated.

Further, in each of the above embodiments, description has been made on the assumption that there is one enemy plane appearing in the three-dimensional game space, but the present invention is not limited to this, and as shown in FIG. 10, for example, A plurality of enemies 110a, 110 in the three-dimensional game space
The present invention can be applied to the case where b, 110c ... Appears.

In this case, for example, one of a plurality of enemies appearing in the three-dimensional game space may be selected, and the above-described correction calculation operation may be performed using the target data of the enemy. In this case, the following are possible ways of selecting the enemy.

The enemy 110c closest to the player's aircraft is selected.

As shown in FIG. 10, the range of the capture angle 40
Within 0, the enemy 110a closest to the player's aircraft 130 is selected (the lock-on range set when the enemy captured by the sight 120 is locked on and the field of view in the viewpoint coordinate system is set as the capture angle). The range of corners is considered, but it may be set irrespective of that.

The capture angle 400 is corrected according to the direction in which the control lever 14 is tilted, and the aircraft 1
