Wait, TZAN made that? I've been watching a few videos of it around. The trick IS to look behind you, because he doesn't move when you're looking at him. Then put him behind a tree, and you take no damage as you put a few miles between the two of you.
I mess around with Unity, so Silver was just joking around and I played along. Normally I wouldnt give away the truth and just let you believe the funny business, but I don't want to take credit (blame) for other peoples work.
