| epsilon : Number
The minimum distance for which the gravity force is calculated.
| MutualGravity | ||
| maxDistance : Number
The maximum distance between particles for the gravitational
effect to be calculated.
| MutualGravity | ||
| power : Number
The strength of the gravity force.

MutualGravity(power:Number = 0, maxDistance:Number = 0, epsilon:Number = 1)
The constructor creates a MutualGravity action for use by an emitter.

addedToEmitter(emitter:Emitter):void
Instructs the emitter to produce a sorted particle array for optimizing
the calculations in the update method of this action.

removedFromEmitter(emitter:Emitter):void
This method does nothing.

|
Checks all particles near the current particle and applies the
gravity force between them.

Hide Inherited Public Properties
Show Inherited Public Propertiesepsilon:Number [read-write]The minimum distance for which the gravity force is calculated. Particles closer than this distance experience the gravity as it they were this distance away. This stops the gravity effect blowing up as distances get very small.
Implementation public function get epsilon():Number
public function set epsilon(value:Number):void
| maxDistance | property |
maxDistance:Number [read-write]The maximum distance between particles for the gravitational effect to be calculated. You can sometimes speed up the calculation of this action by reducing the maxDistance since often only the closest other particles have a significant effect on the motion of a particle.
Implementation public function get maxDistance():Number
public function set maxDistance(value:Number):void
| power | property |
power:Number [read-write]The strength of the gravity force.
Implementation public function get power():Number
public function set power(value:Number):void
| MutualGravity | () | constructor |
public function MutualGravity(power:Number = 0, maxDistance:Number = 0, epsilon:Number = 1)The constructor creates a MutualGravity action for use by an emitter. To add a MutualGravity to all particles created by an emitter, use the emitter's addAction method.
