Due to the success of my previous tutorials about Delegates and Lerp, here comes the next in the series. This time about Collisions, Colliders, Physics and tips around it:
Hope you like it 
Next one will be about Coroutines… unless someone has a better idea? 
UPDATE:
I corrected many mistakes I made in the post. Thanks a lot Adam for the help!
You can read the updated version here: Unity Dojo - Videogame Development, Tips and Design Patterns: How to detect Collisions in Unity. Like a BOSS.

Juan,
I make a small level, It is a FBX model I loaded it into unty 5. I looks very good. I have no collision. But if I use unity 5 cube and make a big box out of it I have collision. So I take that to mean I must use some type of code to my level to get a collision. I just copy you blog and will read to night. If you have time let me know what would be the best way to get collision with a unity 5 cube and my level?
Thank you
