Action Client Reference

Action is a base class for all "non-animating" animations that provides empty implementations for abstract methods and adds a doAction method that will be called to perform the action's operation. While regular animations perform an operation in a sequence of small steps spread over an interval, the actions perform a single operation instantaneously. By default, all actions have a duration of zero. The actions are very useful for defining complex animations.

Action Client Properties

NameDescription
durationLength of the animation in seconds. The default is 1.
eventsThe collection of event handlers for this behavior. This property should only be used by derived behaviors and should not be publicly called by other code.
fpsNumber of steps per second. The default is 25.
id
isActivetrue if animation is active, false if not.
isInitialized
isPlayingtrue if animation is playing, false if not.
