onMapSingleClick EH expects a Boolean. If you are planning to return true and override default behaviour, make sure it is added last.

(ArmA3 1.22) Stack all codes into one PFH will be less demanding than separated calling within multiple PFH. E.g. { [(format [“%1”,_forEachIndex]),”onEachFrame”,_code,[_x]] call BIS_fnc_addStackedEventHandler; } forEach [var0…var100]; //pretty demanding [_id, ”onEachFrame”,{ {_x call _code} forEach [var0…var100]; }] call BIS_fnc_addStackedEventHandler; //faster

It is not possible to override default engine behavior with stacked event handlers. This is because BIS_fnc_executeStackedEventHandler, a function that is called inside BIS_fnc_addStackedEventHandler, always returns false.
