I was wonder about the walk lights on the fun-fair, like these lights on the arm:



The effect on the arm is a walk effect, so, its look like the lights are walking. So, i want to know what function is needed or how to script in lite-c; How to change a skin from a model. If i know that, i put it in a loop, and its a walking light. If i'am wrong, How to script that else?

Best Regards,
Semmi
