InheritanceRotationalQuadraticDrag Inheritance ActionBase Inheritance Object

The RotationalQuadraticDrag action applies drag to the particle to slow it down when it's rotating. The drag force is proportional to the square of the angular velocity of the particle.

Constructor Detail
RotationalQuadraticDrag()Constructor
public function RotationalQuadraticDrag(drag:Number = 0)

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

Parameters
drag:Number (default = 0) — The amount of drag. A higher number produces a stronger drag force.

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

This method does nothing. All derived classes override this method to update each particle every frame.

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.
