Oh here is the updated one:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if (PRESSED(KEY_AIM))
    {
        if (IsPlayerInAnyVehicle(playerid))
        {
            AddVehicleComponent(GetPlayerVehicleID(playerid), 1010);
            new currentveh;
            new Float:angle;
            currentveh = GetPlayerVehicleID(playerid);
            GetVehicleZAngle(currentveh, angle);
            SetVehicleZAngle(currentveh, angle);
            SendClientMessage(playerid, 0xFFFFFFFF, "Your vehicle has been flipped.");
        }
    }
    return 1;
}

And remove the * from

pawn Код:

KEY_AIM*                            (128)
