This action has a priority of 10, so that it executes before other actions.
| Property | Defined By | ||
|---|---|---|---|
| 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 | ||
 | priority : int
Returns a default priority of 0 for this action. | ActionBase | |
| Method | Defined By | ||
|---|---|---|---|
MutualGravity(power:Number = 0, maxDistance:Number = 0, epsilon:Number = 1)
The constructor creates a MutualGravity action for use by an emitter. | MutualGravity | ||
addedToEmitter(emitter:Emitter):void [override]
Instructs the emitter to produce a sorted particle array for optimizing
the calculations in the update method of this action. | MutualGravity | ||
| removedFromEmitter(emitter:Emitter):void
This method does nothing. | ActionBase | |
[override]
Checks all particles near the current particle and applies the
gravity force between them. | MutualGravity | ||

maxDistance:NumberThe 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.

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.

particle:Particle — The particle to be updated.
| |
time:Number — The duration of the frame - used for time based updates.
