OnParticlecollision2D?

I need to detect 2d particle collisions. I've enabled "Send collision messages" on the particle system and added the OnParticleCollision (GameObject o) method but it never hits in this method. Is 2D particle collision messaging allowed in unity?

 

For me this worked:
In the particle system, check the following:


Then add a script to this particle system with the following code:

Code (CSharp):

1. void OnParticleCollision(GameObject other)
2. {
3.      if (other.tag == "Enemy")
4.      {
5.           var enemy = other.GetComponent<Enemy>();
6.           enemy.TakeDamage();
7.      }
8. }
