Shuriken Particle System issue

Hi there guys! Im new to the forums, so if my question is in the wrong place, please put it in the right place!

Well, i have a really weird problem, i don't seem to understand the collision on particles in unity.
i'm making an starfox like game, and the level is an asteroid field, so i made the asteroids changing the renderer on shuriken, and done the things that i need. So the asteroids are all with 0 velocity, so they stand in place too. But the problem is, that even using the "OnParticleCollision" function, i can't get any collision on those asteroids...

I've changed the collision to world, tried everything but it seems that t doesn't work. Even there, if i create a simple particle system, and put a box to collide, at the editor it works perfectly, but when i hit the play button, it wont work too =/

Using the particle system to create the asteroids is really better than ever, but i need to make the asteroids collide, and i cant figure out how i make things collide with them!
i'm not sure if i'm clear enougth here, because i have a baaad english, and i'm scripting in c#, even the code below won't print anything to the console!

void OnParticleCollision(GameObject collisor) {
print(collisor.gameObject.tag);
}

All the tutorials on google, really... suck really bad... they only create a simple particle system that collides with a plane and nothing more...
Please, save my life! Haha

 

As far as I understand it, your asteroids are particles and they are not moving. In this situation it seems you want to detect collisions of other objects with the asteroids. From what I can see, your expectations don't match with what actually exists in Shuriken.
The collision of particles works different than other collisions. It works based on raycasts. When the position of a particle changes, a raycast is performed from the old to the new position in order to find collisions. That means, the shape of the particle is approximated to a point and as such not accurate at all.

So , now i understand ^^ Thanks a lot!

 

Hey Elder don't know if u still struggling with this I had my own troubles with it this post might help.
