How do I create a minimap in the multiplayer game example.

I've edited the multiplayer game example and added a lot of more features, and now I've had a recommendation from someone to add an minimap, I truly agree with this genius idea and I really want to go forward with it, although I'm struggling, please somebody explain how to add it to the multiplayer game example! If you want i'll send you the game in a capx.

There is a good example here:
