protected void	leftStasis() Called when the actor leaves stasis.
protected void	penetratedEnvironment(Vector2f penetration) Notes that the actor collided with one or more things during its advancement.
void	stepLimit(float minDirection, float maxDirection, boolean remove) Adds or removes a step limiter.
boolean	tick(int timestamp) Ticks the participant.
void	transfer(Logic source, Map<Object,Object> refs) Transfers state from the specified source logic.
protected void	updateShape() Updates the shape transform based on the actor's position.
protected void	wasDestroyed() Override to perform custom cleanup.

Constructor Detail

MobileLogic

public MobileLogic()

Method Detail

stepLimit

public void stepLimit(float minDirection,
                      float maxDirection,
                      boolean remove)

Adds or removes a step limiter.

getDirection

public float getDirection()

Returns the direction of the mobile.

tick

public boolean tick(int timestamp)

Description copied from interface: TudeySceneManager.TickParticipant

Ticks the participant.

Specified by:

tick in interface TudeySceneManager.TickParticipant

Parameters:

timestamp - the timestamp of the current tick.

Returns:

true to continue ticking the participant, false to remove it from the list.

getSceneModel

public TudeySceneModel getSceneModel()

Description copied from interface: ActorAdvancer.Environment

Returns a reference to the scene model.

Specified by:

getSceneModel in interface ActorAdvancer.Environment

getPenetration

public boolean getPenetration(Actor actor,
                              Shape shape,
                              Vector2f result)

Description copied from interface: ActorAdvancer.Environment

Checks whether the actor is colliding with anything and, if it is, populates the provided object with the penetration vector (the minimum translation required to cancel the penetration).

Specified by:

getPenetration in interface ActorAdvancer.Environment

Returns:

true if a collision was detected (in which case the result vector will be populated), false otherwise.

collides

public boolean collides(Actor actor,
                        Shape shape)

Description copied from interface: ActorAdvancer.Environment

Checks whether the actor is colliding with anything.

Specified by:

collides in interface ActorAdvancer.Environment
