Particle Collision by size of particle

I’m working on a flame thrower kind of particle system. However, I’d only like the particles to send a callback collision event if the particle is above a certain size. Any ideas how I might accomplish this?

Right now, I’m adding 1 to a int every time a particle collides with my player game object. If that int is above a certain threshold the player dies. What I’d love to avoid the player being near the flame and the smaller little flare things counting toward that threshold.

Here’s a screen for ref:

Thanks!

Bumping this up.

I’ve got a new method but still running into trouble. What I’d love to be able to read is the force by which a particle collides with my kinematic rigidbody 2d.

Any thoughts on that?
