Shapable

public class Ship

extends Body

implements Shapable

A ship. The ship is steered with the methods rotateLeft, rotateRight, and goStraight; the thruster is operated with the methods thrusterOn, and thrusterOff; the firing is controled with the methods fireOn, and fireOff; and the ship is terminated with the method explode.

Constructor Detail

Ship

public Ship(Point2 p)

Creates a ship at position p pointing at a random direction. The mass of the ship is defined by the parameter shipMass and the size by the parameter shipRadius.

Method Detail

getAngle

public double getAngle()

Returns the current angle (in radians).

setAngle

public void setAngle(double t)

Sets the current angle to t (in radians).

setColor

public void setColor(java.awt.Color c)

Sets the color of the ship to c.

advance

public void advance(double dt)

Advances the time dt seconds and updates the position, velocity, and rotation of the ship accordingly. If the parameter decorations is true and the thruster is on, the ship emits a spark at the stern.

Overrides:

advance in class Body

See Also:

thrusterOn(), Spark

isColliding

public boolean isColliding(Body other)

Returns whether the ship collides with the body other. The parameter collisionProjectileShip defines, whether the projectiles can collide with the ships. The parameter collisionShipShip defines, whether the ships can collide with each other.

Overrides:

isColliding in class Body

See Also:

Projectile

rotateLeft

public void rotateLeft()

Sets the steering to the left (i.e., counterclockwise). The rotation speed is defined by the parameter shipSteeringRotationPerSecond.

rotateRight

public void rotateRight()

Sets the steering to the right (i.e., clockwise). The rotation speed is defined by the parameter shipSteeringRotationPerSecond.

goStraight

public void goStraight()

Sets the steering to straight forward.

thrusterOn

public void thrusterOn()

Sets the thruster on. The force of the thruster is defined by the parameter shipThrusterForce.

thrusterOff

public void thrusterOff()

Sets the thruster off.

isThrusting

public boolean isThrusting()

Returns whether the thruster is on.

fireOn

public void fireOn()

Sets the firing on. The firing rate is defined by the parameter shipShotsPerSecond.

See Also:

Projectile

fireOff

public void fireOff()

Sets the firing off.

isFiring

public boolean isFiring()

Returns whether the ship is firing during the current update interval.

See Also:

fireOn(), advance(double)

explode

public void explode()

Explodes the ship and removes it from the universe. If the parameter decorations is true, a cloud of sparks is created at the site of the explosion according to the parameters sparksOnCloud and sparkMaxVelocity.
