What wouldn't work? Please post more detail and use a much better title next time. There's tons of topic titled help.
Maybe the OP expects it in other people rather than having other people expect it in the OP? "Not just anybody..."
Perhaps the OP should explain why the standard FPS controller won't work, and be more descriptive. http://www.youtube.com/watch?v=TU7JjJJZi1Q This is a wonderful example of a poster who A) Gave no information in the title of his post and B) gave no information in his post for people to be able to help him.
It could have only been better if the OP had bumped it less than 20 minutes later for not getting an immediate response.
