TargetVelocity(targetVelocityX:Number = 0, targetVelocityY:Number = 0, rate:Number = 0.1)
The constructor creates a TargetVelocity action for use by an emitter.

Calculates the difference between the particle's velocity and
the target and adjusts the velocity closer to the target by an
amount proportional to the difference, the time and the rate of convergence.

public function TargetVelocity(targetVelocityX:Number = 0, targetVelocityY:Number = 0, rate:Number = 0.1)The constructor creates a TargetVelocity action for use by an emitter. To add a TargetVelocity to all particles created by an emitter, use the emitter's addAction method.

public override function update(emitter:Emitter, particle:Particle, time:Number):voidCalculates the difference between the particle's velocity and the target and adjusts the velocity closer to the target by an amount proportional to the difference, the time and the rate of convergence.
This method is called by the emitter and need not be called by the user.
