I try to use this code to add a magazine when double click on a magazine in inventory :
[] spawn {
test_fnc_test = {
_idc = ctrlIDC (_this select 0);
_selectedIndex = _this select 1;
_unit = player;
_item = lbData [_idc, _selectedIndex];
if (_item isEqualTo "30Rnd_556x45_Stanag") then {
player removePrimaryWeaponItem "30Rnd_556x45_Stanag";
player addPrimaryWeaponItem "30Rnd_556x45_Stanag";
};
};
while {true} do {
waituntil {!(isnull (finddisplay 602))};
((findDisplay 602) displayCtrl 638) ctrlSetEventHandler ["LBDblClick", "_this call test_fnc_test"];
waituntil {isnull (finddisplay 602)};
};
};And the first time, I try, it's work. But when I retry (close inventory and reopen) >> Game Crash
But when I use "LBSelChanged" instead of "LBDblClick", it's works fine.
