Constructor Detail

Walker

public Walker(World world)

Initialise a new Walker with no attached shapes. The walker will have fixed orientation, meaning that the physics engine will not rotate it when subject to torque.

Parameters:

world - the world in which this body will exist

Walker

public Walker(World world,
              Shape shape)

Initialise a new dynamic Walker with a single shape attached. The walker will have fixed orientation, meaning that the physics engine will not rotate it when subject to torque.

Parameters:

world - the world in which this body will exist

shape - the initial shape of this body

Method Detail

jump

public void jump(float speed)

Jump upwards with a given initial speed, after which gravity takes over. The horizontal component of the body's linear velocity is unchanged. This has no effect if the body is already jumping.

Parameters:

speed - the initial vertical speed

startWalking

public void startWalking(float speed)

Start continually setting the horizontal speed of the body, or change the speed if we are already walking.

Parameters:

speed - the horizontal speed (positive to move right, negative to move left)

stopWalking

public void stopWalking()

Stop continually setting the horizontal speed of the body.

destroy

public void destroy()

Description copied from class: Body

Remove this body from the world and notify all registered DestructionListeners. Destruction listeners are notified immediately (before any additional cleanup actions are performed and before the body is removed from the World). This body must not be accessed after being destroyed.

Overrides:
