M3Editor – ARMA 3 Map Editor

With lack of a simple editor in ARMA 3 to add map content and needing to start creating new stuff in ARMA 3, I decided to make a 3D Editor to make it easier to aid in map content editing.

The editor supports saving/opening files directly from Windows, it will export map content in multiple formats including ARMA 3’s Terrain Editor.

Download from A3Launcher.

UPDATE

Here is some code to grab the relative positions for all objects placed.

M3E_fnc_getCenter = {
 private ['_objects', '_asl', '_ax', '_ay', '_az', '_xs', '_xc', '_xz', '_ys', '_yc', '_yz', '_zs', '_zc', '_zz'];
 _objects = [_this, 0, [], [[]]] call BIS_fnc_param;
 _asl = [_this, 1, false, [true]] call BIS_fnc_param;
 _ax = [];
 _ay = [];
 _az = [];
 {
 private ['_position'];
 _position = if (_asl) then {getPosASL _x} else {getPosATL _x};
 _ax pushBack (_position select 0);
 _ay pushBack (_position select 1);
 _az pushBack (_position select 2);
 } foreach _objects;
 _xs = 0;
 _xc = {_xs = _xs + _x; true} count _ax;
 _xz = _xs / _xc;
 
 _ys = 0;
 _yc = {_ys = _ys + _x; true} count _ay;
 _yz = _ys / _yc;
 
 _zs = 0;
 _zc = {_zs = _zs + _x; true} count _az;
 _zz = _zs / _zc;
 
 [_xz, _yz, _zz]
};
 
M3E_fnc_getRelPositions = {
 private ['_objects'];
 _objects = [_this, 0, [], [[]]] call BIS_fnc_param;
 _center = [_objects] call M3E_fnc_getCenter;
 _center set [2, 0];
 _arr = [];
 _str = '';
 {
 private ['_relpos'];
 _relpos = [getPos _x, _center] call M3E_fnc_subArr;
 _line = [typeOf _x, _relpos, getDir _x];
 _str = _str + (str _line) + (toString [10]);
 _arr pushBack _line;
 } foreach _objects;
 copyToClipboard _str;
_str
};
 
[M3E_insertedObjects] call M3E_fnc_getRelPositions;

UPDATE

Made this HTML/JS tool to convert CFG to SQF the editor can open: https://dl.dropboxusercontent.com/u/135243/M3Editor-Cfg2Sqf/convert.htm

  1. Hey, do you have an old version on m3editor available? 0.18 crashes after like 20 minutes without fail. I don’t remember this happening on the version that appended “_project” to the filename when you saved. I think I remember getting that version from epochmod.com but the link doesn’t work anymore.

  2. Tried disabling BE but it still crashes. I also dont get the option to unblock the .dll files. Just keeps crashing. Any help?

  3. I’m unable to save a project, I’ve tried saving to clipboard etc…. but it just crashes my game. Suggestions?

  4. Hi, since the steam update i can’t seem to save my projects. I get an error about a .dll file. Where can i find it and what do i do with it?

  5. Your new update, I cant wait to load it. Just something has changed since I installed it last. I put the @m3editor into client, still have the key file on the server, but you have dll folder and another folder. Where do I place them again, or if its changed? Sorry I looked everywhere even the video again. I am not exactly sure where I place them again.

    Thanks

    P.s love your work, you allowed me to do many custom bases. Custom map loading and I want this update.
