[SDK] GetPlayerUserID fails

[ir0nic]

Hi.
I want to get the entity index (player index so far) from userid. In serverplugins, I simply use m_pEngine->GetPlayerUserID, works well, but on clientside (so in hacks..) it returns 0 - every time.
Is there another way to get the index by userid?

OMG! Forum fail. Sorry - please move.

Thanks!

pEngine->GetPlayerForUserID(userid);

Works fine for me?
