How to make a radar/map

Question

Hey everyone, I am making a car game, where your view is from above the car.... I was wondering if anyone knew if it is possible to make a sort of radar map where you can see slightly more of what's around you from a birds eye perspective. It's like most games (like grand theft auto) and you can see the buildings and stuff like that.

Any answer would be appreciated!!!

You could take a look at the Wiki or this answer How do I attach a Camera to a GUI (for a Mini map).

As ina said, you can create another camera view, indeed. Make a camera and position it somewhere above the car, point it directly down towards the car, and make sure it follows the car around (if car rotation is not a problem, make it a child of the car GameObject).

Then, if you have Unity Pro, make a RenderTexture and make the Map camera render into it, then display that texture in a GUI.Box.

If you don't have Unity Pro, you need to fiddle with the viewport settings of the Map camera to ensure it renders its content into a sub-window of the screen.

In any case, it might be a good idea to make the Map camera orthographic.
