Set driven key research 2

 The following link is how to set up a set driven key just using a joint system alone without any controllers. I watched the video to rekindle my knowledge on set driven keys and try to gather some more knowledge on them. I found out that the way I remembered of doing set driven keys was the way the person in the video was doing them also that the way I was thinking about doing set driven keys using joints were the same. So I must of learned the standard way of doing set driven keys.
