Give me a couple of weeks and I'll be releasing a template hopefully. It's taking longer than I hoped due to other non GameSalad things. There's no way I'm going to explain how to make one in a forum post. That's long!
There is one downside to the template though... it uses loops, and left and right expression comparisons so will only work in the nightly builds until version 11 of GameSalad is released.
