Class Gun

java.lang.Object
  Gun

Direct Known Subclasses:

BulletBillGun, LaserGun

public class Gun
extends java.lang.Object

Gun: shoots (i. e. emits) missiles (like a Factory). Handles shooting timeouts. Can be put into a spaceship.

Field Summary

protected double	abs_speed Absolute value of the speed vector that's set to missiles.
protected double	angle Angle the missiles are launched with (to y axis, value in radians).
protected int	direction Direction the gun is facing.
protected int	dx X distance of launched bullets from spaceship center.
protected int	dy
static int	initial_recovery Initial recovery time of this kind of gun.
protected int	level Level of the gun (and thus of the missiles).
protected int	recovery The number to which timer is set after a bullet has been launched.
protected int	side Side the gun (and so the missiles) is on.
protected Vector	speed Speed the missiles are set to when launched.
protected int	timer This variable determines how many turns the gun has to wait before it may emit another bullet.

Field Detail

timer

protected int timer

This variable determines how many turns the gun has to wait before it may emit another bullet. It is counted down; when it reaches 0, we can shoot. Otherwise, the gun will just shoot out thin air (i. e., a null pointer) when asked for a missile.

See Also:

missile()

recovery

protected int recovery

The number to which timer is set after a bullet has been launched. (I. e., the number of turns that will pass between two missiles.

speed

protected Vector speed

Speed the missiles are set to when launched.

side

protected int side

Side the gun (and so the missiles) is on.

level

protected int level

Level of the gun (and thus of the missiles).

dx

protected int dx

X distance of launched bullets from spaceship center.

dy

protected int dy

See Also:

dx

abs_speed

protected double abs_speed

Absolute value of the speed vector that's set to missiles.

angle

protected double angle

Angle the missiles are launched with (to y axis, value in radians).

direction

protected int direction

Direction the gun is facing. Allows for easier dy calculation in subclasses.

See Also:

dy

initial_recovery

public static int initial_recovery

Initial recovery time of this kind of gun. (Without alteration by FasterGuns, that is.)
