Hi, i’m a new user…
I would like to use particle system as weapon in my game, but i don’t try any method to detect particles collision with enemies…
I searched the forum but I found no answer to my problem; it can do this?
how can I create laser weapon?

Thank you

Something like a laser weapon can be done with raycast.

Are you talking about a laser beam that shoots far and does damage to things it touches, or are you talking about a sword type weapon?
