Actually OnPlayerUpdate gets called 100+ times a sec.
You can make an EX update

pawn Код:

public OnPlayerConnect( playerid )
{
    SetTimerEx( "OnPlayerUpdateEx", 1000, 1, "i", playerid );
    return 1;
}

later, replace your OnPlayerUpdate with this

pawn Код:

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