Question by leonalchemist · Nov 25, 2014 at 10:13 PM · 2dcollisioncollidershooter

2D shooter, 3d or 2d colliders?

Gonna work on a basic 2d space shooter and was wondering which is better in terms of accuracy and performance for bullet collisions and such, any pros and cons I should be aware of before starting to code? thx

Well, 2D collision has a whole extra dimension less to resolve than 3D. So... if your game only operates in 2D, use 2D physics.

I don't understand why people would use 3D physics for a 2D game? 2D collision is just fine. Only difference between 2D and 3D collision is that 3D can also detect it on the Z angle. If it's JUST a 2D game, Z angle is basically pointless.
