The Age action operates in conjunction with the Lifetime
initializer. The Lifetime initializer sets the lifetime for
the particle. The Age action then ages the particle over time,
altering its energy to reflect its age. This energy can then
be used by actions like Fade and ColorChange to alter the
appearence of the particle as it ages.
The aging process need not be linear. This action can use
a function that modifies the aging process, to ease in or out or
to alter the aging in other ways.
When the particle's lifetime is over, this action marks it
as dead.
When adjusting the energy this action can use any of the
easing functions in the org.flintparticles.common.energy package
along with any custom easing functions that have the same interface.
easing:Function
The easing function used to modify the energy over the
lifetime of the particle.
Implementation public function get easing():Function public function set easing(value:Function):voidpublic function Age(easing:Function = null)
The constructor creates an Age action for use by an emitter.
To add an Age to all particles created by an emitter, use the
emitter's addAction method.
Parameters | easing:Function (default = null) |

override public function update(emitter:Emitter, particle:Particle, time:Number):void
Sets the energy of the particle based on its age and the easing function.
This method is called by the emitter and need not be called by the
user
Parameters
| emitter:Emitter — The Emitter that created the particle.
|
| |
| particle:Particle — The particle to be updated.
|
| |
| time:Number — The duration of the frame - used for time based updates.
