Shuriken Particle System GetParticles() not working
I am trying to get a effect like the old "rotation axis" in the new Shuriken particle system.
If there is a easy method for this please tell me.
My approach to solve this problem was to write a script, which changes the velocity of every particle, but it seems as if GetParticles() does not work for me.
Now the real question: How do I have to use this method?
Thats strange, I haven't seen that method anywhere and I can't get it from anything.
Not even the scripting reference shows this method anywhere?
Example script that will make all particles red:
public class ParticleBufferAccess : MonoBehaviour {
private ParticleSystem.Particle[] particles = new ParticleSystem.Particle[1000];
void LateUpdate() {
int length = particleSystem.GetParticles(particles); int i = 0;
while (i < length) {
particles[i].color = Color.red; i++;
}
particleSystem.SetParticles(particles, length); }
}
Thanks @WBDN, I was trying to move particles in other ways but GetParticles(particles) always returned "0", so no particles at all.
Finally the solution was to allocate space for the particles on declaration:
private ParticleSystem.Particle[] particles = new ParticleSystem.Particle[1000];
This is hidden in the bottom in Unity's documentation example, so it would be great if you improve it a little bit :)

I've noticed that there's a delay before the GetParticles() function has any particles available, that might be why there's no particles? I got it working by emitting in Start() and then getting particles in Update().
