Overrides com.badlogic.gdx.scenes.scene2d.actions.TemporalAction.begin.

Doc from com.badlogic.gdx.scenes.scene2d.actions.TemporalAction.begin.

public void reset()

Overrides com.badlogic.gdx.scenes.scene2d.actions.TemporalAction.reset.

Implements com.badlogic.gdx.utils.Pool.Poolable.reset.

Doc from com.badlogic.gdx.scenes.scene2d.Action.reset.

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 restart().

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

setAlphaback to summary
public void setAlpha(float alpha)
setColorback to summary
public void setColor(Color color)

Sets the color to modify. If null (the default), the actor's color will be used.

updateback to summary
protected void update(float percent)

Implements abstract com.badlogic.gdx.scenes.scene2d.actions.TemporalAction.update.

Doc from com.badlogic.gdx.scenes.scene2d.actions.TemporalAction.update.

Called each frame.
