Base player pointer?!?!?

Okay I'm good with d3d and c++ but I just epic fail in memhacking
how the hell do you find base player pointer of a game?
I know how to use ollydbg and stuff but yeah nvr managed to get the hang of mem hax

I'd look into engine hooks before trying to memhack, give us some info(what game etc)

edit: uses unreal engine 3 and gameguard.
Main executable is packed with asprotect(can't unpack on vista)
I think I'm the only one devving for that game in mpgh now got chams to work
