ParticleEmitter.particles

Description

Returns a copy of all particles and assigns an array of all particles to be the current particles.

Note that after modifying the particles array you must assign it back to the particleEmitter to see the change. Particles with energy of zero or less will be killed when assigning the particles. Thus when creating a complete new particle array, you need to set the energy of all particles explicitly.

var emitter: ParticleEmitter;

function Start() {
	emitter = GetComponent.<ParticleEmitter>();
}


function LateUpdate () {
	// extract the particles
	var particles = emitter.particles;
	
	for (var i = 0; i < particles.Length; i++) {
		// Move the particles up and down on a sinus curve
		var yPosition = Mathf.Sin (Time.time) * Time.deltaTime;
		particles[i].position += Vector3 (0, yPosition, 0);
		
		// make the particles red
		particles[i].color = Color.red;
		// modify the size on a sinus curve
		particles[i].size = Mathf.Sin (Time.time) * 0.2;
	}
	
	// copy them back to the particle emitter
	emitter.particles = particles;
}
