Particles emit in the same direction twice if they hit a collider

Im trying to make a simple fireball particle system that ends when it hits a collider. The particle system is a child of my player and will emit in the right direction, but if the first emit hits another collider the second emit will always emit in the same direction as the first one. I end the particles by getting the particles from the particle system, setting their remaining lifetimes to 0, and setting them back in the particle system. I think this might be the issue but im not sure why and if theres another way to get rid of the particles. I just started using the shuriken particle system and im not sure how it all works so any help would be appreciated.
