He said he doesn't have 2 of them..

Maybe, you got one in your includes, or...

You can also use an external one, a timer instead:

pawn Код:

public OnPlayerConnect( playerid )
{
    SetTimerEx( "OnPlayerUpdateEx", 500, 1, "i", playerid );
    return 1;
}

forward OnPlayerUpdateEx( playerid );
public OnPlayerUpdateEx( playerid )
{
    // Your OnPlayerUpdateCode...
    return 1;
}
