Method Detail

draw

public void draw(java.awt.Graphics g)
Description copied from class: Sprite
This method is called by the SpritePanel to tell the sprite to draw itself. It is not meant to be called directly. Subclasses should override this method to draw an appropriate picture. The method in this class just draws a tiny black dot at the location of the sprite.

Overrides:
draw in class Sprite

fire

public void fire()
Fire a bullet by adding a Bullet sprite to the panel that contains this GunSprite. The bullet's speed is given by the gun's bulletSpeed property. The direction of the bullet is given by the direction the gun is pointing. (If the gun is not in a panel, this method does nothing.)

getAngle

public double getAngle()

getBulletSpeed

public double getBulletSpeed()

setAngle

public void setAngle(double degrees)
Sets the direction that the gun is pointing. The angle is given in degrees, with zero degrees pointing up. Positive angles are measured clockwise from that position; negative angles, counterclockwise.

setBulletSpeed

public void setBulletSpeed(double speed)
Sets the speed for bullets fired by this gun.
