That would be awesome, because the language looks almost foreign to me. I actually have some TGF experience with other static engines but Sonic Worlds seems to be a lot more sophisticated (I realize this when I'm staring down the trigonometric equations and chains of alterable value) Something as simple as gravity seemed to be expressed rather abstractly and impossible for me to tweek.
I'm assuming for the wall jump you just change the gravity when the wall detector overlaps the backdrop and you're holding, let's say, left, for a limited amount of time, then you can either wall jump or fall off naturally. Or you could make it like in 'Splosion Man where if you slide enough, you get a charged jump.
(Edit) Oh, and I forgot to mention that I've yet to actually do any editing of the latest build. I'm still mostly theoretical until I actually know what I'm doing.
