I want to add tail to rockets in my game because some of them are dark and besides it look cool. So I decided to use particle system.
The “Bullet” (hasn’t decided if it’ll be bullet or actual rocket) and tail are in one object group. Positioning “tail” direction of particles against bullet/rocket movement shouldn’t be hard.
Unfortunately though I don’t know how to pick right objects so bullet and tail would be in same group instance (so I don’t get funky result like tail positioning against rocket that is flying in opposite direction). How to do that?
