unity3d - Unity Assets doesn't collision with player, but cubes etc. does

Question

I want to test making games with Unity the first time but I don't get, why the player only collides with normal elements like cubes, planes etc. (so elements, which you can create in unity), but with assets like a floor or something it doesn't work. The player just goes through the asset objects. I'm sure I have to change something at the asset objects, but what?

Answer 1

Try adding a suitable type of Collider (ref), the default Unity GameObjects come with Colliders preattached.
