Im Using a particle system for a bullet looking effect with a max and min emmision of 1. the only thing thats wrong is the force isnt local it goes the same way even if my charecter turns does anyone know how to fix it so its local axis not world and will go forward even if i turn
Ye this is actually a pretty funny question for me since I asked the same thing to myself not more than a week or so ago.
The answer is quite simple, don't use particle emission for that. Instantiate and destroy a prefab, and put whatever effects you want on the object instead. It's easier to do, costs no extra work as far as I could tell and it can help you with collisions aswell.
If you want to determine force based on the character orientation you would have to create vector with x,y,z force components using trigonometry.
