Classpublic class Velocity
InheritanceVelocity Inheritance InitializerBase

The ColorInit Initializer sets the velocity of the particle. It is usually combined with the Move action to move the particle using this velocity.

The initial velocity is defined using a zone from the org.flintparticles.twoD.zones package. The use of zones enables diverse ranges of velocities. For example, to use a specific velocity, a Point zone can be used. To use a varied speed in a specific direction, a LineZone zone can be used. For a fixed speed in a varied direction, a Disc or DiscSector zone with identical inner and outer radius can be used. A Disc or DiscSector with different inner and outer radius produces a range of speeds in a range of directions.

Constructor detail
Velocity()constructor
public function Velocity(zone:Zone2D = null)

The constructor creates a Velocity initializer for use by an emitter. To add a Velocity to all particles created by an emitter, use the emitter's addInitializer method.

Parameters
zone:Zone2D (default = null) — The zone to use for creating the velocity.

public override function initialize(emitter:Emitter, particle:Particle):void

This method does nothing. All derived classes override this method to initialize each particle created by the emitter.

Parameters
emitter:Emitter
 
particle:Particle
