How to set the orbit Camera??

Hi, im recently discover the TGE world. when i was playing with it, i found out that there is a way to move the camera (which is orbiting above the player) and the player too (like God of war), without touching the source code, only scripting.... now, i searched all the resources and forums sections and tried all of those things, but none work for me. If anyone can tell me how use the orbit camera (with a example, a step by step thingy or a little bit of code sample to understand better how it works), i would really aprecciate it.

Thanks for reading
