Hello, folks. Is there any chance you share a faster or more elegant way to write the same result below? Code goal: at the mission starts, search once all named markers and remove all found markers that aren't area markers (rectangles and ellipses), saving the result in a list for further purposes. Pretty sure even the first code line below could be smarter/complete. // Search through all markers on the map with the prefix "mark_" and append them in a list: _areaMarkersOnly = allMapMarkers select {_x find "mark_" isEqualTo 0}; // result example: ["mark_1", "mark_garbage", "mark_2"] but unfortunately including markers with unwanted shapes. { // forEach in _areaMarkersOnly: // It will be needed to identify what will be deleted later: _index = _areaMarkersOnly find _x; // If the marker (_x) is NOT rectangle and is NOT ellipse, so... if ( (markerShape _x != "RECTANGLE") AND (markerShape _x != "ELLIPSE") ) then { // delete this marker from my list: _areaMarkersOnly deleteAt _index; }; } forEach _areaMarkersOnly; SOLVED! Below, you see the code that works for me after the community advice: _acceptableShapes = ["RECTANGLE", "ELLIPSE"]; _prefix = "mark_"; if ( !_debug ) then { // Selecting only relevant markers: _areaMarkersOnly = allMapMarkers select { (_x find _prefix == 0) AND {(markerShape _x) in _acceptableShapes} }; } else { // For debugging purporses, the way to select the relevant markers here it is slightly different. Now selecting all markers shapes: _areaMarkersOnly = allMapMarkers select { _x find _prefix == 0 }; { // forEach _areaMarkersOnly: // _x index in the list, need it to delete _x from the list: _markerIndex = _areaMarkersOnly find _x; // if the marker has no the shapes acceptables, do it: if ( !((markerShape _x) in _acceptableShapes) ) then { // delete the marker from the list: _possibleMinefields deleteAt _markerIndex; // delete the marker from the map: deleteMarker _x; // and print this messages: systemChat format ["DEBUG > Marker '%1' has NO a rectangle or ellipse shape to be considered a area marker.", _x]; }; } forEach _areaMarkersOnly; };
