(Removed faulty comment by Mlacix. onMapSingleClick has to return a boolean at the end. That's all.)

''onMapSingleClick'' have some problem to run '''[[execVM]]''' command. The problem coused by the execVM itself, but there is a way to fix it. Here you can see two example.
Not working:
  onMapSingleClick "if (_alt) then {[_shift,_alt,_pos] execVM 'arty_menu.sqf'};";
  onMapSingleClick "if (_alt) then {_a = [_shift, _alt, _pos] execVM 'arty_menu.sqf'; };";
  _a = [_shift, _alt, _pos] execVM 'arty_menu.sqf'; //You can create it in and outside of the onMapSingleClick scope.
The difference is that if you want to use execVM in that scope, then you need to add it to a variable (global and local both work). This is an '''execVM''' issue, not an '''exec''' one. With *.SQS files it's working without any problem.

Define action performed when user clicks in map by executing command string. the string receives 3 (localised in scope) variables:
  • _pos: Array - Clicked position
  • _units: Array - Units which were selected (via function keys) before opening the map (may be non-functional in Arma)
  • _shift, _alt Boolean - Whether <Shift> or <Alt> were pressed when clicking on the map
When click is processed, code should ultimately return true back to the engine. If false is returned, default processing by the game engine is done. Return value of any other type (including Nothing) is an error. In such case default processing by the game engine is done, and error message may be displayed. The code is executed on every click, until the Command is
  • removed via onMapSingleClick "", or
  • replaced by onMapSingleClick "SomeOtherCommand(s)"


onMapSingleClick command
command: String
Return Value:


Example 1:
onMapSingleClick "'SoldierWB' createUnit [_pos, group player]; true;" ArmA: Creates a soldier unit at the position clicked.
Example 2:
onMapSingleClick "_grp1 move _pos; onMapSingleClick ''; true;" ArmA: Orders "_grp1" to move to position clicked. Disables further map-click actions.
Example 3:
onMapSingleClick """SoldierWB"" createUnit [_pos, group player]; true;" OFP: In OFP single quotes cannot be used for string definition, so two double-quotes have to be used instead.

See my Multiple OnMapSingleClick script to allow you to add multiple events to the onMapSingleClick event. Some minor editing of the scripts would be required to use them in Arma.
