  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of a simulation game machine according to the present invention.
The simulation game machine 10 according to the present embodiment is a virtual world (game space) in which a fighter (first flying body, airplane) and a missile (second flying body) having different flight principles in the real world (real world). ) Is a flight simulation game machine that develops the game by flying.
Here, “the flight principle is different” means that the flight principle is different. For example, fighter A and fighter B do not have different flight principles. Also, the flight principle is not different between fighters and passenger aircraft. On the other hand, fighter aircraft and missiles have different flight principles. This is because fighter planes fly with wings, but missiles do not depend on the attached wings and fly with thrust from the rocket engine.

  The simulation game machine 10 also includes an input device 20, an input control circuit 30, a monitor 40, a video control circuit 50, a speaker 60, a sound control circuit 70, a memory 80, a control unit 90, and the like. .

The input device 20 is a device such as a joystick, a missile launch button, or a switch operated by a player.
The input control circuit 30 is a circuit that transmits an input signal input from the input device 20 to the control unit 90.
The monitor 40 is a device that outputs the image data from the video control circuit 50 as a visible image.
The video control circuit 50 is a circuit that controls the synthesis and output of image data.
The speaker 60 is a device that outputs audio data from the sound control circuit 70 as an audible sound.
The sound control circuit 70 is a circuit that controls the synthesis and output of audio data.
The memory 80 includes a ROM, an EEPROM, a RAM, and the like, and includes a first storage unit 81, a second storage unit 82, and a program storage unit 83.
The first storage unit 81 is a part that stores parameters related to fighters, and the second storage unit 82 is a part that stores parameters related to missiles (details of the parameters will be described later).
The program storage unit 83 stores a simulation game machine program for operating the simulation game machine 10. The simulation game machine program includes a common flight control routine (flight engine) used for flight control of fighters and missiles (details of the common flight control routine will be described later).
The control unit 90 is a part that performs overall control of the simulation game machine 10, and operates a common flight control routine using parameters stored in the first and second storage units 81 and 82. A flight control unit 91 that performs flight control of fighters and missiles is provided.
When controlling the flight of a fighter aircraft, the control unit 90 controls the flight of the fighter aircraft by operating a common flight routine using parameters related to the fighter aircraft. In addition, when a missile is launched from a fighter, the flight of both the fighter and the missile must be controlled. In that case, the parameters related to the fighter and the missile are used alternately. Flight control of fighters and missiles is performed by operating the flight routine.

FIG. 2 is a diagram for explaining axes used for flight control of the flying object.
The flying object (fighter and missile) of the present embodiment is controlled by X-axis pitching, Y-axis yawing, and Z-axis rolling, and the control unit 90 receives an input signal from the input device 20. The aircraft is controlled by converting the values into the X-axis, Y-axis, and Z-axis values.
X-axis pitching is a movement around the left-right axis of the flying object, that is, a movement of swinging the nose up and down.
Y-axis yawing is a movement around the vertical axis of the flying object, that is, a movement of swinging the nose from side to side.
The Z-axis rolling is a movement around the front-rear axis of the flying object, that is, a movement of the flying object tilted to the right or left.

FIG. 3 is a diagram for explaining the details of the parameters related to the missile. The parameters related to the missile include the following.
(1) Rotation angle X data (see FIG. 3A)
This data shows the relationship between the missile speed (KT; knot) and the rotation angle X (deg / s). For example, if the missile is flying at 200 KT, the missile will pitch at about 35 deg / s.
(2) Suppression angle data (see FIG. 3B)
This data shows the relationship between missile speed (KT) and hold-down angle (deg). For example, if the missile is flying at 200 KT, the hold angle is about 1 degree. Here, the restraining angle is an angle indicating how much the flying body has raised the nose with respect to the Z axis in FIG.
(3) Maximum restraint angle data (see Fig. 3 (C))
This data shows the relationship between missile speed (KT) and maximum hold-down angle (deg). For example, if a missile is flying at 200 KT, the maximum hold-down angle is about 2 degrees. Here, the maximum restraining angle is a value indicating how far the flying body can raise the nose.

(4) Acceleration / deceleration degree (see FIG. 3D)
This data shows the relationship between the value (KT) obtained by subtracting the current missile speed from the missile target speed and taking the absolute value, and the addend and subtraction. For example, if the target speed of the missile is 400 KT and the missile is currently flying at 200 KT, the absolute value obtained by subtracting the current missile speed from the target speed of the missile is 200 KT. In this case, about 0.8 KT is added to the current missile speed per frame for acceleration, and about 2.3 KT per frame is subtracted from the current missile speed for deceleration.
(5) Drag coefficient (see Fig. 3 (E))
This data shows the relationship between the restraining angle (deg) and the drag coefficient. For example, if the restraint angle of the missile is 1 degree, the drag coefficient is about 0.9. Here, the drag coefficient is a coefficient determined by the shape of the flying object and the value of the angle of attack. Considering an aircraft flying at 1000 KT, if the restraint angle is 0 degree, it can fly as it is at 1000 KT, but if the restraint angle is 1 degree, it will fly at 900 KT (1000 KT x 0.9). To come.
(6) Air coefficient (See Fig. 3 (F))
This data shows the relationship between altitude (FEET; feet) and air coefficient. For example, if the flying object is flying at an altitude of 60,000 feet, the air coefficient is about 0.7. Note that the range of the air coefficient is 0.1 (high resistance) to 1.0 (no resistance).

  These parameters are related to missiles, but there are separate data on fighters. Also, the number of parameters used need not be exactly the same for missiles and fighter aircraft. For example, missiles use 6 parameters, but fighter aircraft use 10 parameters. Also good.

FIG. 4 is a diagram for explaining the flow of processing of a common flight control routine.
In S101, an input of the rotation amount around the XZ axis is received from the input device 20. The X-axis performs fighter aircraft pitching processing, and the Z-axis performs fighter aircraft rolling processing. The direction of missile travel is determined by pitching and rolling, just like fighters.
In the case of a fighter aircraft, processing is performed using an input value from the input device 20, but in the case of a missile, first, the angle on the XZ plane to the target is obtained from the coordinates of the target and the missile.
Next, the rotation angle of the Z axis is obtained. Specifically, the input value Z is obtained from “input value Z = (rotation angle ÷ 4000 deg / s × 127) × frame rate”. Here, the frame rate is a value representing how many times the screen is updated per unit time. “127” is an arbitrary numerical value for rounding the value in order to facilitate processing. “4000 deg / s” is a value specific to the missile.
Further, the rotation angle of the X axis is obtained. Specifically, the input value X is obtained from “input value X = (rotation angle ÷ angular velocity × 127) × frame rate”. The range of the input values X and Z is -127 to +127.

In S102, it is checked whether the incoming data is in the range of -127 to +127.
In S103, the angular velocity is obtained by “angular velocity = (rotation angle ÷ 127 × input value) ÷ frame rate”. The rotation angle X is obtained according to the speed from FIG. The missile rotation angle Z is a fixed value, and is 4000 deg / s ÷ frame rate.

In S104, the moving speed per frame of the flying object is obtained from the maximum speed, acceleration, deceleration degree, fuel consumption, drag coefficient, and air coefficient.
Here, the maximum speed is a fixed value and is the maximum speed during horizontal flight.
As for the degree of acceleration and deceleration, the target speed is compared with the current speed from FIG. 3D, and the change speed per frame is obtained by the difference.
The fuel consumption is a fixed value, and the target speed is designated as the maximum speed for the designated number of seconds, and the target speed is designated as 0 when the designated number of seconds elapses.
As for the drag coefficient, the amount of movement per frame is calculated from the angle of attack from FIG.
As for the air coefficient, the amount of movement per frame is determined according to the air state (altitude) from FIG.

In S105, the angle of attack is obtained according to the speed from FIG.
In S106, the maximum angle of attack is obtained according to the speed from FIG.
In S107, the rotation angle and the moving speed are added to the current angle and speed.
And flight control is performed by repeating S101-S107.
Note that the flight control routine shown here is an example, and other flight control routines may be used if a common control routine is used for the fighter and the missile.

Thus, according to the present embodiment, the following effects are obtained.
(1) By operating a common flight control routine, flight control of fighters and missiles is performed, so only one flight control routine is required, and memory usage and development time can be reduced. In addition, the efficiency of program creation and missile behavior control can be simplified.
(2) By using a common flight control routine, fighter aircraft and missiles move to some extent, and more natural and reasonable movements can be expressed in virtual space.

(3) When a flight control routine for an airplane exists in advance, the missile can be easily controlled by diverting it. In this way, it is possible to control the missile to have a control stick as if it were steered on the XZ axis and headed toward the target.
(4) A highly versatile flight control routine can be provided for the control of a wide variety of aircraft.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications and changes are possible, and these are also within the equivalent scope of the present invention.
(1) The simulation game machine may be installed in a facility such as a game center or may be a home game machine. In addition, a program for performing the control as described above may be distributed and used as a mobile phone game.
(2) Although the missile has been described as an example of launching from a fighter aircraft, it may be launched from a ground turret or the like.
(3) The missile parameters may be different for short-range missiles and long-range missiles.
