己解决【 _items = items player;_wanted = [ "ACE_personalAidKitItem", "ACE_salineIVItem", "ACE_bloodIVItem", "ACE_bananaItem" ];
if ( _wanted findIf { _x in _items } > -1 ) then {
player addaction ["Eat Food","eat.sqf"]; player addaction ["Drink","drink.sqf"];
};】

不过在编辑器里的查找出来的类名后面会带item. 必须把这个给删掉，测试了好久才发现问题出在这里，在此特别感谢吧主的指点

_items = items player;_recipe = [ ["item1", 5], ["item2", 3], ["item3", 98]];_crafting_allowed = true;{ _item = _x#0; _wanted_num = _x#1; _num = {_x isEqualTo _item} count _items; if (_num < _wanted_num) then { _crafting_allowed = false };} count recipe;if ( _crafting_allowed ) then {// script};
