Ok, I said I would post my plugin today, so here it is. Do not be deceived by it, though. It's not as far as it looks. Think of all the other ucodes I have to implement. Also, I'm about to venture into one of the hardest parts: texturing and texture combining. Luckily, I have some experience in this, from writing a glide wrapper (which was never actually released).
I'm thinking about making my glide plugin open-source, so that others can help too. At least if I had to leave the project at some point, somebody else could pick it up. It would be sad to see an attempt at something that is wanted so much go to waste. Anyway, it's not going open-source yet, since it's progressing too fast. Once progress slows, I'll consider doing it.
By the way, can someone try running SF Rush and tell me how it works?
to Cyberman:
Yes, Winglide does come with source. Just search on yahoo for "Winglide". I don't have time to redo it for Glide3x, though.
