Sorry if my question looks dumb, I can’t find an precise answer by myself (also sorry for the english mistakes, it’s not my native language).
I am wondering if it’s OK to switch my 3D project into a 2D project by changing the Default Behavior Mode on the Editor Setting and replacing Colliders, Rigidbodies and OnTrigger functions to their 2D equivalents.
I began a project on 3D mode with a 2D gameplay and set the Z scale to 0.05f to have sprite-like objects (basic objects like spheres), but now the project is getting serious and I’d like to spare useless 3D calculations.
So here are my questions, should I start a new 2D project and refactor my game or can I just change the Editor Settings and replace 3D components by their 2D equivalents ? Do I risk performance issues if I change the mode and replace the components ? What does it involves in the back yard?
(I’m on Unity 4.5 btw)
Thanks a lot for your help
