Method Detail

setActor

public void setActor(Actor actor)

Description copied from class: Action

Sets the actor this action will be used for. This is called automatically when an action is added to an actor. This is also called with null when an action is removed from an actor. When set to null, if the action has a pool then the action is returned to the pool (which calls Action.reset()) and the pool is set to null. If the action does not have a pool, Action.reset() is not called.

This method is not typically a good place for a subclass to query the actor's state because the action may not be executed for some time, eg it may be delayed. The actor's state is best queried in the first call to Action.act(float). For a TemporalAction, use TemporalAction#begin().

Overrides:

setActor in class Action

act

public boolean act(float delta)

Description copied from class: Action

Updates the action based on time. Typically this is called each frame by Actor.act(float).

Specified by:

act in class Action

Parameters:

delta - Time in seconds since the last frame.

Returns:

true if the action is done. This method may continue to be called after the action is done.

isEnabled

public boolean isEnabled()

setLayoutEnabled

public void setLayoutEnabled(boolean enabled)
