The ScaleImage action adjusts the size of the particles imnage as it ages.
It uses the particle's energy level to decide what size the particle
should be.
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.
If you also want to adjust the mass and collision radius of the particle, use
the ScaleAll action.
endScale:Number
The scale factor for the particle when its energy
is 0 - usually at the end of its lifetime. A scale of 1 is normal size.
Implementation public function get endScale():Number public function set endScale(value:Number):voidstartScale:Number
The scale factor for the particle when its energy
is 1 - usually at the start of its lifetime. A scale of 1 is normal size.
Implementation public function get startScale():Number public function set startScale(value:Number):voidpublic function ScaleImage(startScale:Number = 1, endScale:Number = 1)
The constructor creates a ScaleImage action for use by an emitter.
To add a ScaleImage to all particles created by an emitter, use the
emitter's addAction method.
Parameters | startScale:Number (default = 1) |
| |
| endScale:Number (default = 1) |

override public function update(emitter:Emitter, particle:Particle, time:Number):void
Sets the scale 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
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.
