planet revolves around the sun

i know there is a way to do this but i can’t figure it out.
i’m trying to get one object to revolve around another objects
center in the game engine.
some one refresh my memory please.

Snap your 3D Cursor to the sun and make your Rotation Pivot the Cursor (period key).

%<

Then his animation won’t be a real rotation but a translation and he’ll need quite a lot of keys to get something vaguely related to an ellips.

Better to make the planets ride on cyclic curves that are easy to shape and whose speed can be controled.

Have a look.
