Package	org.flintparticles.twoD.actions
Class	public class AntiGravity
Inheritance	AntiGravity GravityWell ActionBase

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.

This is the same as the GravityWell action with a negative force.

Property detail

power

property

power:Number [read-write]

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

Implementation
public function get power():Number
public function set power(value:Number):void

Constructor detail

AntiGravity

()

constructor

public function AntiGravity(power:Number, x:Number, y:Number, 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` — The strength of the force - larger numbers produce a stronger force.

	`x:Number` — The x coordinate of the point away from which the force pushes the particles.

	`y:Number` — The y coordinate of the point away from which the force pushes the particles.

	`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 if they were this distance away. This stops the anti-gravity effect blowing up as distances get small.
