You can try this:

pawn Код:

public OnPlayerSpawn(playerid)
{
    if (!logged[playerid])
    {
        SendClientMessage(playerid, COLOR_RED, "This server requires you to login before spawning. Please reconnect and use the /login command.");
        Kick(playerid);
        return 1;
    }
    return 1;
}

You can also try it OnPlayerRequestSpawn:

pawn Код:

public OnPlayerRequestSpawn(playerid)
{
    if(!logged[playerid])
    {
        SendClientMessage(playerid,COLOR_RED,"Be aware: You are not logged in yet!");
        return 0;
    }
    return 1;
}
