I keep getting a "zero divisor" error when trying to select from an array after using the find command. The basic situation is; 16 people each with their own individual waypoints. When the units reach the waypoint, the following is executed: For units in group 1: nul = [this,1] execVM 'law\setRotation.sqf'; For units in group 2: nul = [this,2] execVM 'law\setRotation.sqf'; setRotation.sqf contains the following: params [["_subject", objNull],["_typeCode", 0]]; if (_typeCode == 0) then { //Insert Code to generate error report here }; if (_typeCode == 1) then { _unitsAlpha = [ pak_mainyu1_2, pak_mainyu1_3, pak_mainyu1_4, pak_mainyu1_5, pak_mainyu1_6, pak_mainyu1_7, pak_mainyu1_1, pak_mainyu1_8 ]; _positionInQueue = _unitsAlpha find _subject; _bearingsBriefing_alpha = [ 271.587, 250.801, 225.084, 202.869, 172.511, 147.108, 26.615, 20.786 ]; _bearingFrom = _bearingsBriefing_alpha select _positionInQueue; _startPos = getPosAtl _subject; _watchTarget = [_startPos,3,_bearingFrom] call BIS_fnc_relPos; _watchTarget set [2,1.8]; _subject doWatch _watchTarget; }; if (_typeCode == 2) then { _unitsBravo = [ pak_mainyu2_2, pak_mainyu2_3, pak_mainyu2_4, pak_mainyu2_5, pak_mainyu2_6, pak_mainyu2_7, pak_mainyu2_1, pak_mainyu2_8 ]; _positionInQueue = _unitsBravo find _subject; _bearingsBriefing_bravo = [ 271.587, 250.801, 225.084, 202.869, 172.511, 147.108, 26.615, 20.786 ]; _bearingFrom = _bearingsBriefing_bravo select _positionInQueue; _startPos = getPosAtl _subject; _watchTarget = [_startPos,3,_bearingFrom] call BIS_fnc_relPos; _watchTarget set [2,1.8]; _subject doWatch _watchTarget; }; What i can't figure out is why it's trying to select a value that's out of range. There are 8 units in each group, a matching set of 8 names in the _unitsX arrays, and 8 entries within the bearing array. Should be a simple case of 1 - obtain unit name from waypoint completion 2 - find name within array 3 - select corresponding bearing from the bearing array I ran a separate test to go through the same process 1 by 1 which passed without error, so I'm guessing it's to do with some of these waypoints being completed at the same time: _testGroup = [ pak_mainyu2_1, pak_mainyu2_2, pak_mainyu2_3, pak_mainyu2_4, pak_mainyu2_5, pak_mainyu2_6, pak_mainyu2_7, pak_mainyu2_8 ]; { player sideChat (format ["Subject: %1",_x]); _subject = _x; _unitsBravo = [ pak_mainyu2_2, pak_mainyu2_3, pak_mainyu2_4, pak_mainyu2_5, pak_mainyu2_6, pak_mainyu2_7, pak_mainyu2_1, pak_mainyu2_8 ]; _positionInQueue = _unitsBravo find _subject; player sideChat (format ["PosInQ: %1",_positionInQueue]); _bearingsBriefing_bravo = [ 271.587, 250.801, 225.084, 202.869, 172.511, 147.108, 26.615, 20.786 ]; //player sideChat (format ["Subject: %1, Position: %2",_subject,_positionInQueue]); _bearingFrom = _bearingsBriefing_bravo select _positionInQueue; player sideChat (format ["BearingFrom: %1",_bearingFrom]); _startPos = getPosAtl _subject; _watchTarget = [_startPos,3,_bearingFrom] call BIS_fnc_relPos; _watchTarget set [2,1.8]; _subject doWatch _watchTarget; sleep 3; } forEach _testGroup; Maybe there's something to do with using local variable handles that I'm not understanding here.
