I just wanted to know what to do to rotate an object continuously around a fixed axis, like a fan, in the game engine. I’m trying to make a plane turbine spin.

Add an “Always” Sensor, link it to an “AND” Controller, link that to a “Motion” Actuator, from there change the “Rot” rates.

I recommend you take a gander at the Blender Game Engine Tutorial

in logic bricks, make this combonation for the turbine object (the one that will spin)

always---------and----------motion: rot

and increase the rotation value for whatever axis you are working with.
