Constructor Detail

DelegateAction

public DelegateAction()

Method Detail

setAction

public void setAction(Action action)

Sets the wrapped action.

getAction

public Action getAction()

act

public final 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.

restart

public void restart()

Description copied from class: Action

Sets the state of the action so it can be run again.

Overrides:

restart in class Action

reset

public void reset()

Description copied from class: Action

Resets the optional state of this action to as if it were newly created, allowing the action to be pooled and reused. State required to be set for every usage of this action or computed during the action does not need to be reset.

The default implementation calls Action.restart().

If a subclass has optional state, it must override this method, call super, and reset the optional state.

Specified by:

reset in interface Pool.Poolable

Overrides:

reset in class Action

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

toString

public String toString()

Overrides:

toString in class Action
