Hi all

I am new at Sketchucation, and at programming Ruby too.

I have a SU model, consisting of one big box and a servo. The servo is controlled by a slider (as used in sketchyphysics)

I just want to be able to move the slider and store the position of the box (it can be the center) in a global variable.

That's it

Please help me but please write in the most simple way so I can understand.

Thanks, I really appreciate your help
