OnParticleCollision not always fired

Physics

Hi everybody,

I have this very simple projet where two particle systems emit on demand a particle towards a sprite with a box collider attached to it, and add an impulse force to this sprite when collision happens.

Problem is, sometimes the onParticleCollision event is not fired, the particle just goes through the collider.

I tried setting collision detection to “continuous”, I tried the DontGoThroughThings script, or decreasing the timestep parameters, nothing solves the problem.

This thread: http://stackoverflow.com/questions/21461774/how-to-prevent-rigidbody-from-passing-through-other-colliders seems to match my problem, but the particles I use are slow, and the force I am adding is weak, so I have trouble admitting speed would be the cause of my problem.

Any ideas? :frowning:

I want to revive this thread, as I am dealing with the same issue. I have also applied exactly the same ‘fixes’ as ceyssette did, yet none of them seem to work. Apparently the collision is inconsistent. I am using FPS controller, and, without moving the camera, I continuously shoot an effect. 6/10 collisions in the same angle will not take place. It should be noted that the effect is exactly the same (and to be even more specific, it’s being reused by ObjectPooling).

Has anyone found a solution thus far?

Cheers!
