I want to add physics to the Donut component (the Game.blend in the assets).

This is my unity window

Expanded the Donut component

My donut also have a rigid component that I accidentally clicked,but I didn't add any scripts into it.

Answer 1

I found the solution

1. Add a collider component in the game object inspector
2. Click on the None material and replace it by the Physic Material folder.
