IgnoreCollision with Particle System

Questions & Answers
1

Is it possible to IgnoreCollision between a Rigidbody and a ParticleSystem?

Or anything I can do after I detect the collision that I want to ignore?

PS: Like in IgnoreCollision() I need the case that the Particles and the Rigidbody don’t collide at all physically.

(I know that I can specify Layers to collide. But the Players are colliding with their own particle system(Gun Effect) and if I disable the collision using Layer, there are a lot of other Players and the Gun Effect is not colliding with them too (which makes the particle system affectless and pointless.)

I need to IgnoreCollision between each ParticleSystem and its own parent)

You could put the particle system game object as a variable on your player script and when:

void OnCollisionEnter(Collider other){

if(other.gameObject != particleSystem){

// you just ignored the child particle system
}
