well, that's because in the powder toy code there are alot of open ifs and such and you might-of accedentally deleted a } or forgot a }. I've done it before
"I have managed to code an element into the code, without looking at the wiki (except setting up the project) and failed. The code is flawless, yet C++ keeps saying that part of my code 'expects a }' when it is in the middle of my coding!"
Cool, but we can't guess what error messages you are getting nor what code you are using.
