How to set the collision area of a particle?

Actualy I found that the particle collision only happens when the center of the particle, but not the surface of the particle ,is collided with another object, so I can’t know when the collison happens if the particles is very big. How to solve this problem?

I'm not sure how, but your best bet it to offset the particle's material.

It is not possible. Particles can only register collisions with their center point.
You have to use real GameObjects with colliders instead.
