      • setAction

        public void setAction​(Action action)
        Sets the wrapped action.

      • getAction

        public Action getAction()

      • delegate

        protected abstract boolean delegate​(float delta)

      • 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 is attached to. This also sets the target actor if it is null. This method is called automatically when an action is added to an actor. This method 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 an action 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

      • setTarget

        public void setTarget​(Actor target)
        Description copied from class: Action
        Sets the actor this action will manipulate. If no target actor is set, Action.setActor(Actor) will set the target actor when the action is added to an actor.
        Overrides:
        setTarget in class Action

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class Action
