I started a project about 2 months ago, when I created it I included no built in assets. Now, when I try to add collisions, everybody has it built in but me. How do I get the built in collisions? I tried going to Assets > Import Package > Physic Materials, but I’m pretty sure that’s not the right one. Please help.
Colliders are components that you place on your game objects. There are simple/primitive ones and mesh-based.
Select a game object and add a collider via Component->Physics.
I already have a box colliders on all of my objects.
And rigibodies?
