The ParticleField class lets you create a field of particles in an easy way. The particles are positioned randomly within limits that you set. The following lines demonstrate how you can instantiate a particle field and add it to the scene:
var particleField:ParticleField = new ParticleField(material,1000,5, 1800,1800,1800); scene.addChild(particleField);
When you create a particle field, you don't have to instantiate the Particles or Particle classes—the ParticleField class takes care of this.
The ParticleField constructor has one required and five optional parameters as shown in the next table:
