Could anyone help me with the next step to http://cs.elderscrolls.com/constwiki/index.php/Rotating_an_object_around_another_object_with_a_script that is on the TES wiki. Do I add an OnActivate to get it to work and if so where?
Would appreciate any help, totally confused

Depends on what you are trying to do.

If you want an object to rotate around the player you could just put that script on the object that is being rotated and it should run from the start of the game (just make sure you put a moveTo player in there to get the object in the same cell as the player).

You can use an OnActivate block to initiate the rotation. Just use a short variable to keep track if the object has been activated or not.

That article was mainly meant to provide the math for other modders to adapt into their own scripts.

Thank you. That helped me figure it out. Cheers
