Is it possible to randomly emit particles but choosing their positions in a 2D grid?

Hello,

Is it possible to randomly emit particles but choosing their positions in a 2D grid?

For example:



The blue points are spawning possibilities and the red points are the particles currently emitted.
I didn't find the right way to do it when using the Particle System component.
Can someone give me an hint on how I could achieve it please ?

Thanks!

 

Code (CSharp):

1. public class Emitter : MonoBehaviour
2. {
3.     public ParticleSystem ps; // plug in via the Inspector
4.  
5.     public void Emit(Vector3 pos)
6.     {
7.          ParticleSystem.EmitParams ep = new ParticleSystem.EmitParams
8.          {
9.               position = pos,
10.               // LOTS of other parameters if you want to specify color, velocity, etc
11.          };
12.  
13.          ps.Emit(ep, 1);
14.     }
15. }

You set up the particle system to have the material / texture you want and some initial parameters. Then you can manually emit at particular positions on your grid, selecting from the possible emit spots.

 

Thank you for answering!
I think I got it, I have to define the positions myself and my particle system should emit the point texture where I want.
