stock GetOnLinePlayers()
{
    new OnLine;
    for(new i, g = GetMaxPlayers(); i < g; i++)
        if(IsPlayerConnected(i))
            OnLine++;
    return OnLine;
}
Why do you want to specifically know if there's 1 connected?

Because there's going to be a message shown if the player is alone in the server, and when the second player joins, the message should be hidden to next players. I want to understand how can you detect a certain amount of players from online list. Example: "5 players needed to start the gamemode" and then it hides the message and players can play.

pawn Код:
GetOnlinePlayers();
if(OnLine == 1) ...
I believe that would work?

You're dead wrong, and don't throw out guesses like that again... Reason being that the GetOnlinePlayers function, isn't going to hand the variables it made, as they aren't global, to the rest of the script.

OnLine ONLY exists 'within' that function.

You use what it returns to point out what happened to the code that called it.
Код:
if(GetOnlinePlayers()>5){Commence}
else if{Don't}
^^ This check very likely doesn't actually work, but it's the idea that the actual variable isn't visible to the code at that level, and thus it should error out saying the variable isn't defined when you compiled it.

You should try this. I have explained everything to you below.

PHP код:
/*
Script Documentation:
Made by: brauf
Tested: Yes
*/
#include <a_samp>
new PlayersOnline; // this variable stores a integer of the players online
GetPlayersOnServer() // function to get players on server
{
    PlayersOnline = 0; // reset online players each time when trying to fetch it otherwise "PlayersOnline" will just keep increasing each time (++) with each check
    for(new i; i < MAX_PLAYERS; i++) // do a loop of all player slots available (1, 2, 3 - 1000), if player slot 1 or 2 or 3 has a valid player connected (IsPlayerConnected) then increase "PlayersOnline" by 1 (++)
    {
        if(IsPlayerConnected(i)) // a check to see if player is online on that id
        {
            PlayersOnline++; // increase "PlayersOnline" by 1 if there is a online player on
            return PlayersOnline; // return "PlayersOnline" which tells the server how much players are on
        }
    }
    return PlayersOnline; // return "PlayersOnline" which stores the value of how much players are on
}
public OnPlayerConnect(playerid)
{
    GetPlayersOnServer(); // execute this function "OnPlayerConnect" so when a player logs in, it tries to detect how much players are on
    if(PlayersOnline == 1) // if online players = 1, then there is only 1 player online
    {
        SendClientMessage(playerid, -1, "Looks like the server is empty, except you."); // send a message
    }
    return 1;
}
