Putting an array reference into a local variable in C#

Unity Engine
1

Hello, I’m trying to convert this sample JS code from the ParticleEmitter.particles documentation into C#:

// Attach this script to an existing particle system.
function LateUpdate () {
    // extract the particles
    var particles = particleEmitter.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 system
    particleEmitter.particles = particles;
}

Starting with the first line in the block:

ParticleEmitter[] particles = particleEmitter.particles;

I’m getting stuck with the following error:

error CS0029: Cannot implicitly convert type UnityEngine.ParticleEmitter.particles' to UnityEngine.ParticleEmitter[ ]’

I’ve only been using C# for a few days; would someone mind pointing me in the right direction? I just want to assign a reference to the particles array to a local variable. (Yes, I’ve searched the forums and google… :? )

Thanks,
John

you want an array of particles, not an array of particle EMITTERS as your error explains :wink:

Ahah! Why yes, that makes perfect sense now… :sweat_smile:

Thanks,
