| Class | public class Fade |
| Inheritance | Fade  ActionBase Object |
Usually a particle's energy changes from 1 to 0 over its lifetime, but this can be altered via the easing function set within the age action.
This action should be used in conjunction with the Age action.

public function Fade(startAlpha:Number = 1, endAlpha:Number = 0)The constructor creates a Fade action for use by an emitter. To add a Fade to all particles created by an emitter, use the emitter's addAction method.
This action has a priority of -5, so that the Fade executes after color changes.

override public function update(emitter:Emitter, particle:Particle, time:Number):voidSets the transparency of the particle based on the values defined and the particle's energy level.
This method is called by the emitter and need not be called by the user
