The Flash animation makes nodes appear at the begin keyframe and disappear at the end keyframe. This is done via the visibility of nodes and not via their transparency.

Adding the animation#

First, choose nodes that you want to show and hide.

Then, double-click on the Flash animation effect in the Animation panel of the Animator.

This animation has 4 keyframes:

  • between keyframes 1 and 2 the specified nodes will stay hidden
  • at the keyframe 2 the specified nodes will become visible and between keyframes 2 and 3 they will stay visible
  • at the keyframe 3 the specified nodes will become hidden and between keyframe 3 and 4 they will stay hidden

Move the keyframes of the animation as needed.


You can always move the keyframes of the animation.


You can change how the parameters are interpolated between the frames by modifying the Easing curve.
