[AK47317]

try this

pawn Код:

public OnPlayerDisconnect(playerid, reason)
{
    new playname[MAX_PLAYER_NAME];
    new userfile[128];
    new string[128];
    GetPlayerName(playerid, playname, sizeof(playname));
    format(string, sizeof(string), "%s.ini", playname);
    if(fexist(string))
    {
        new Float:pHealth, Float:pArmour;
        new INI:file = INI_Open(string);
        INI_WriteInt(file, "Level", GetPlayerScore(playerid));
        INI_WriteInt(file, "Money", GetPlayerMoney(playerid));
        INI_WriteInt(file, "Health", GetPlayerHealth(playerid, pHealth));
        INI_WriteInt(file, "Armour", GetPlayerArmour(playerid, pArmour));
        INI_WriteInt(file, "Skin", GetPlayerSkin(playerid));
        INI_Close(file);
    }
    return 1;
}

EDIT: why this

pawn Код:

INI_WriteInt(file, "Level", GetPlayerScore(playerid));

used GetPlayerScore? xD use AccInfo [ playerid ] [ ENUM ] ;
