Classpublic class Accelerate
InheritanceAccelerate Inheritance ActionBase

The Accelerate Action adjusts the velocity of each particle by a constant acceleration. This can be used, for example, to simulate gravity.

Constructor detail
Accelerate()constructor
public function Accelerate(accelerationX:Number, accelerationY:Number)

The constructor creates an Acceleration action for use by an emitter. To add an Accelerator to all particles created by an emitter, use the emitter's addAction method.

Parameters
accelerationX:Number — The x coordinate of the acceleration to apply, in pixels per second per second.
 
accelerationY:Number — The y coordinate of the acceleration to apply, in pixels per second per second.

Method detail
update()method
public override function update(emitter:Emitter, particle:Particle, time:Number):void

Applies the acceleration to a particle for the specified time period.

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.
