BoundingBox(left:Number = 0, top:Number = 0, right:Number = 0, bottom:Number = 0, bounce:Number = 1)
The constructor creates a BoundingBox action for use by
an emitter.

Tests whether the particle is at the edge of the box and, if so,
adjusts its velocity to bounce in back towards the center of the
box.

| bounce | property |
bounce:Number [read-write]The coefficient of restitution when the particles bounce off the sides of the box. A value of 1 gives a pure pure elastic collision, with no energy loss. A value between 0 and 1 causes the particle to loose enegy in the collision. A value greater than 1 causes the particle to gain energy in the collision.

public function BoundingBox(left:Number = 0, top:Number = 0, right:Number = 0, bottom:Number = 0, bounce:Number = 1)The constructor creates a BoundingBox action for use by an emitter. To add a BoundingBox to all particles created by an emitter, use the emitter's addAction method.

| update | () | method |
public override function update(emitter:Emitter, particle:Particle, time:Number):voidTests whether the particle is at the edge of the box and, if so, adjusts its velocity to bounce in back towards the center of the box.
This method is called by the emitter and need not be called by the user
Parametersemitter: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.
