You know how to get a mob up... but not down.. Though it goes about the same way.. Why am I starting to think you copy/pasted whatever you have already in the first place? :/

Or, his existing system could be faulty. <_<
Of course, even then, he might've posted his code.

Anyway, kid who wants the help, people usually don't just make systems of this importance in something other than a demo or library largely available. One reason is because it's a bit harder to search the forum than the hub for demos and libraries.

Anyway, Kunark has made a good gravity system. It's a bit bloated, but should work at any rate. It's in one of his older works. There is a like a pack of his game's source somewhere, I beleive on the hub.

I haven't really looked at this one, but it works.

See if that helps.
