InheritanceAntiGravity Inheritance GravityWell Inheritance ActionBase Inheritance Object

The AntiGravity action applies a force to the particle to push it away from a single point - the center of the effect. The force applied is inversely proportional to the square of the distance from the particle to the point.

The strength of the anti-gravity force - larger numbers produce a stronger force.

Constructor Detail
AntiGravity()Constructor
public function AntiGravity(power:Number = 0, position:Vector3D = null, epsilon:Number = 1)

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

Parameters
power:Number (default = 0) — The strength of the force - larger numbers produce a stronger force.
 
position:Vector3D (default = null) — The point in 3D space that the force pushes the particles away from.
 
epsilon:Number (default = 1) — The minimum distance for which the anti-gravity force is calculated. Particles closer than this distance experience the anti-gravity as it they were this distance away. This stops the anti-gravity effect blowing up as distances get very small.
