I'm making an fps-style game, and for this, knowledge on the particle system is basically required. I'm wondering how to work the particle system at all, but I can learn that elsewhere. I'm asking how to make the particles appear whenever I click, as sparks from the gun the character wields. This will happen once every shot, and I want the sparks to come from the barrel of the gun, and be able to move with the character (To fire from your position, in your camera direction). I don't know much about the particle system in general, but I can learn that on my own, I just needed to know this. I'll probably ask more questions related to my game as I move through development. Any answer much appreciated.
