So is there any way to create particle form like this?
Thanks!

I’ve done very little scripting with Particles (beyond turning them on an off), so this was an interesting question for me. Here is a script that uses a Mathf.Sin() to create a wave as you’ve outlined.

var magnitude = 1.0;
var period 	= 2.0;
var maxParticles = 1000;

private var particles : ParticleSystem.Particle[];
private var ps : ParticleSystem;

function Start () {
	ps = particleSystem;
	particles = new ParticleSystem.Particle[maxParticles];
}

function Update() {
	if (ps.particleCount > particles.Length) {
		particles = new ParticleSystem.Particle[ ps.particleCount];
	}
	
 	ps.GetParticles(particles);
	for(var i = 0; i < ps.particleCount; i++) {
 		var dist = particles*.position.x - transform.position.x;*

particles_.position.y = Mathf.Sin((dist % period) / period * 2.0 * Mathf.PI) * magnitude;_
* }*

* ps.SetParticles(particles, ps.particleCount);*
}

Apparently you cannot get the maximum number of particles in script, so I use a variable plus some code that will resize the array if the variable is wrong.
