| Property | Defined by | ||
|---|---|---|---|

MatchVelocity(maxDistance:Number, acceleration:Number)
The constructor creates a MatchVelocity action for use by an emitter.
| MatchVelocity | ||
|
addedToEmitter(emitter:Emitter):void
Instructs the emitter to produce a sorted particle array for optimizing
the calculations in the update method of this action.
| MatchVelocity | ||
|
getDefaultPriority():Number
Returns a value of 10, so that the MatchVelocity action executes
before accelerating actions that act on particles independently of
other particles, like Acceleration and GravityWell.

 |
removedFromEmitter(emitter:Emitter):void
This method does nothing.
| ActionBase | |
|
Checks all particles near the current particle and applies the
acceleration to alter the particle's velocity
towards their average velocity.

| MatchVelocity | () | constructor |
public function MatchVelocity(maxDistance:Number, acceleration:Number)The constructor creates a MatchVelocity action for use by an emitter. To add a MatchVelocity to all particles created by an emitter, use the emitter's addAction method.
ParametersmaxDistance:Number — The maximum distance, in pixels, over which this
action operates. The particle will match its velocity other particles
that are at most this close to it.
|
|
acceleration:Number — The acceleration applied to adjust each
particle's velocity to match that of the other particles near it.

| update | () | method |
public override function update(emitter:Emitter, particle:Particle, time:Number):voidChecks all particles near the current particle and applies the acceleration to alter the particle's velocity towards their average velocity.
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.
