Apply Physics2D to 3D Game Objects - Unity3D

问题

Is it possible to use Physics 2D components(rigidbody2d,collider2d..etc) on 3d Game objects. I am planning develop 2 game with some of 3d model.

Thanks!

It is not, however what you can do with rigidbody3d is lock the physics movement and rotation on it. For example, if you only ever wanted it to move along the x and y axis of your game, in the inspector just tick the freeze z movement box for the rigidbody component.
