Finding the Dimensions of an Undeclared Object from the Eden editor

[Rand_em_x_y_z 0]

So, I'm trying to build a script that will display the dimensions of a certain object. It seems simple enough, however the catch here is that the object in question will not be declared into the mission and will be NULL.

So I implemented the following script for the given purpose but I am not getting the correct results. I'm getting 0 s' no matter what object I form reference to.

_objname = "I_MRAP_03_F";
_box = missionNamespace getVariable[_objname, objNull] ;

_box_dim = boundingBoxReal _box ;

_p1 = _box_dim select 0;
_p2 = _box_dim select 1;

//systemChat format["%1,%2,%3", _p1 select 0, _p1 select 1, _p1 select 2];


_maxW = abs ((_p2 select 0)- (_p1 select 0));
_maxL = abs ((_p2 select 1)- (_p1 select 1));
_maxH = abs ((_p2 select 2) - (_p1 select 2));

systemChat format["width: %1", _maxW];
systemChat format["length: %1", _maxL];
systemChat format["Hidth: %1", _maxH];

I'm guessing that because the object in question (in this case a HEMPT truck) is not declared into the mission itself, its dimensions will return all zeroes? Any suggestion on how to fix?

sizeOf "I_MRAP_03_F" will return 11.8862  // too big as usual

 

getNumber (configfile >> "CfgVehicles" >>"I_MRAP_03_F" >> "mapSize") will return 6.55  // far better. Similar to highest value of boundingBoxReal of the object.
