I got a building, but i just walks right through it? -What to do :S
You add colliders so you don’t walk through it.
The simplest way is to add mesh collision, and use the same mesh as the collider. Of course, you can also make a special collider mesh, or if the building is box orientated, and not enterable, use a simple box collider

How do i add the collision??
-Thanks for the answers 
Its box orientated, but how do i add it?
In your project list if you click on your building mesh, there’s a checkbox to add collision to the model
Made it, Thanks for the help
