control ctrlMapScreenToWorld [x, y]
Parameters:
control: Control - map control

You can get the screen coordinates by the UI Event Handlers onMouseButtonDown, onMouseButtonUp, onMouseButtonClick, onMouseButtonDblClick. The return Array is in 2D, you can use it with all set-position commands. _x = returnArray select 0; _y = returnArray select 1;

The command parameters are screen position coordinates, which may not equate to the map control's coordinates. A map control's screen coordinates and size can be found use the ctrlPosition command. This is an issue when using the Arma 3 in-game map, which is not fullscreen (all previous titles used full screen map controls, so map control coords did equate to screen coords).

This example creates a RscMapControl and hints you the [x,y] position where you clicked. 0 spawn { disableSerialization; _map = findDisplay 46 createDisplay "RscCredits" ctrlCreate ["RscMapControl", -1]; _map ctrlSetPosition [0,0,1,1]; _map ctrlCommit 0;
_map ctrlAddEventHandler ["mouseButtonDown", { _ctrl = _this select 0; _x = _this select 2; _y = _this select 3;
_pos = _ctrl ctrlMapScreenToWorld [_x, _y]; hint format ["pos: %1", _pos]; }]; };
