- When broadcasting a compileFinal'ed variable using publicVariable or its variants, the variable also becomes final on the other client(s) and/or the server. Also, compileFinal does not prevent event handlers from being removed or overwritten.
- Posted on May 27, 2017 - 11:58 (UTC)
- in Arma 3 v1.70.141838, compileFinal also works for profileNamespace and uiNamespace. But be careful with that.
- Posted on Oct 23, 2020 - 10:39 (UTC)
- Change with Arma 3 patch 2.00, compileFinal is now unable to store code type variables in profileNamespace!

Making a base class read only using HashMapObjects
Class_Dog = compileFinal createHashMapObject [ // Properties ["#type", "Dog"], ["owner", objNull], ["legs", 4], ["health", 100], ["vehicleclass", "Dog_Base_F"], ["vehicle", objNull], // Constructor ["#create", { params [["_owner", objNull], ["_vehicle", objNull]]; if ([_owner, _vehicle] findIf {isNull _x} != -1) exitWith {}; _self set ["owner", _owner]; _self set ["vehicle", _vehicle] }] ]; NewDog = createHashMapObject [ [["#base", Class_Dog]], [player_1, createVehicle [Class_Dog get "vehicleclass", [0,0,0], 0, [], "NONE"]] ]; NewDog set ["owner", player_2]; NewDog get "owner"; // returns player_2 Class_Dog set ["owner", player_1]; // Error: Read Only
