Well, I think it is there You can go to YouTube and search Frogmindgames and both are same I guess :-D
The post @AKAI2002 linked, there is one link for variables in it, and one more for "lookAt" variable.
The link brought me to a video that had audio, but didn't play the video. I looked up the video on YouTube, and I found it though. Thanks for mentioning it to me.
