Constructor Detail
TurnTowardsPoint()Constructor
public function TurnTowardsPoint(point:Vector3D = null, power:Number = 0)

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

Parameters
point:Vector3D (default = null) — The strength of the turn action. Higher values produce a sharper turn.
 
power:Number (default = 0) — The point towards which the particle turns.

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.
