.:: Bots United ::. - SetGravity()

Trying to make a mod, where I have a flying character. But I need everything else to have regular gravity.
I tried in \src\dlls\GameInterface.cpp

Code:

void CServerGameClients::ClientActive( edict_t *pEdict, bool bLoadGame )

{

   ...

   pPlayer->SetGravity(0.0f);

}

it does a whole lot of nothing. my character still has regular gravity set on them. Is there a way I can set it's weight to 0, or setGravity on it to 0! *&$(@*#&(
Help please!! :surrender:
