Как сделать чтобы техника блокировалась как в арме 2?

нашёл вот такой файлик из a3_epoch_server.pbo 

 

private ["_vehicle","_value"];

_vehicle = _this select 0;
_player = _this select 2;

if (isNull _vehicle) exitWith {};

// Token check
if !([_player,_this select 3] call EPOCH_server_getPToken) exitWith {};
if (_player distance _vehicle > 20) exitWith {};

// Group access
_plyrUID = getPlayerUID _player;
_plyrGroup = _player getVariable["GROUP", ""];

_lockOwner = _plyrUID;
if (_plyrGroup != "") then {
_lockOwner = _plyrGroup;
};

_lockedOwner = "-1";
_vehSlot = _vehicle getVariable["VEHICLE_SLOT", "ABORT"];
_vehLockHiveKey = format["%1:%2", (call EPOCH_fn_InstanceID), _vehSlot];
if (_vehSlot != "ABORT") then {
_response = ["VehicleLock", _vehLockHiveKey] call EPOCH_fnc_server_hiveGETRANGE;
if ((_response select 0) == 1 && typeName(_response select 1) == "ARRAY" && !((_response select 1) isEqualTo[])) then {
_lockedOwner = _response select 1 select 0;
};
};

_isLocked = locked _vehicle in[2, 3];

// Lockout mech
if (!_isLocked || _lockedOwner == _lockOwner || _lockedOwner == "-1") then {

_value = _this select 1;

if (_value) then {
["VehicleLock", _vehLockHiveKey, EPOCH_vehicleLockTime, [_lockOwner]] call EPOCH_fnc_server_hiveSETEX;
};

if (local _vehicle) then {
_vehicle lock _value;
} else {
if (_value) then {
[["lockVehicle", _vehicle], (owner _vehicle)] call EPOCH_sendPublicVariableClient;
} else {
[["unlockVehicle", _vehicle], (owner _vehicle)] call EPOCH_sendPublicVariableClient;
};
};
};

 

думаю дело в нём, помогите пожалуйста разобраться новичку.
