OK so, where to start:
1) I loaded into arma op using dayz commander and added the map tool (@John C-5).
2) In game I've put all my objects on the map and when I finished I've saved it.
3) So into my documents find the mission file and then I've got 2 files.
4) I used the .sqf, I went into it deleted the things I didn't need (at the top) and added the if {server] to the top. I then create a new folder in my dayz_server.sqf called it maps. I put the buildings file in there. I then closed the if statement at the bottom of the buildings file. Then I went into my server _functions file ( in dayz_server.sqf) I went to the very bottom and added an execute line for the file I added in.
( I didn't have any MAP_ etc I was all land )
When I join the server it starts but when im loading into the game, the server fails to authenticate. Please can anybody help ?? I've done this thread of the top of my head ( I did it yesterday ) so its can the most accurate.. I can upload the files if needed just ask ;) / Thanks
Example of my 'objects'
_vehicle_0 = objNull;
if (true) then { _this = createVehicle ["Land_A_GeneralStore_01", [7105.5522, 7802.2627, -0.99499023], [], 0, "CAN_COLLIDE"];
_vehicle_0 = _this;
_this setDir -102.32523; _this setPos [7105.5522, 7802.2627, -0.99499023];
};
