pawn Код:

new Level[MAX_PLAYERS];

At the top of your mode...

Then you can do stuff like OnPlayerConnect

pawn Код:

Level[playerid] = 1;

Which will set the players level to 1 when they first join.

and when checking if a player has a certain level

if(Level[playerid] == 2){...}

etc...

It's pretty simple, thats the way i'd do a level system.
