When disassembling the UAV the game deletes its crew but doesn't delete the group, which remains empty in game forever since it doesn't have its isGroupDeletedWhenEmpty set. This is a bad practice as missions with UAVs and without special handling for this issue will end up with lots of empty useless groups.
Solution would be to set isGroupDeletedWhenEmpty flag to engine-created groups so they're cleaned up after emptying.
if(isNil"testeh") then {
testeh = player addEventHandler ["WeaponAssembled", {call assembledfunc}];
arr = [];
};
assembledfunc = {
params ["_unit", "_vehicle"];
arr pushBack group _vehicle;
};
onEachFrame {
hintSilent (arr apply {[str _x, format["isGroupDeletedWhenEmpty=%1", isGroupDeletedWhenEmpty _x], str units _x] joinString "\n"} joinString "\n\n");
};I wish we could control deletion of UAV units by the engine too.
Didn't check what exactly changed yet (is group deleted or has delete when empty flag set?) but I noticed that you can't get that empty group when vehicle is dissembled unless you put it into a variable. Lets expand Disassembled event handler to also include reference to the group that deleted units had?
The group has deletewhenempty flag set to true now. Make another ticket for that other thing with repro
Tested, looks fine. Won't bother with extending Disassembled event handler, not critical at all.
