I am creating a game that is a top down space shooter. It is in 2D, therefore I have constrained the rotations of the objects so that it can only rotate in the Y-axis. I also want them to always be at Y = 0; even if they manage to somehow get on top of each other, I want them to 'fix' their positions.
I have been reading the forums and there is a post about 2D games and the recommendation was to use a point to plane constraint. I went over the demo but it confused me. If someone can clarify and explain how to set up the point to plane constraint (especially given my case) I'd be grateful. Thanks!
