Try this code, I did it fast ..

Code:

new Exp[MAX_PLAYERS]; //experience
new Lv[MAX_PLAYERS]; //level
forward LevelUp(playerid);

Ongamemodeinit :

Code:

SetTimer("LevelUp", 1000, false);

out of any callback :

Code:

public LevelUp(playerid)
{
if(LevelNext(playerid) >= Exp[playerid]) {
Exp[playerid] = 0;
Lv[playerid] ++;
SetPlayerScore(playerid, GetPlayerScore(playerid) + 1);      
}
}

Code:

stock LevelNext(playerid){
return (Lv[playerid] * 5);
}

Only to increase the experience: Exp[playerid] ++;

Do not promise anything eh
