Try using this

Код:

public OnPlayerRequestSpawn(playerid)
{
    if(Logged[playerid] == 0)
    {
        SendClientMessage(playerid,red,"ERROR: You must log in before spawning.");
        return 0; //Making sure the player won't spawn.
    }
    //Player is logged, so they sawn.
    return 1;
}

You need to return 0 so the player can't spawn.
