问题

我在探索如何创建一个基于文本的游戏，并且我正在尝试处理在房间之间移动的部分。我已经解决了这一部分，并且创建了一个非常详细的地图，你可以输入“go north”等命令。唯一的问题是，游戏非常枯燥，我想加入物品的概念。为了创建房间，我做了以下的代码：
```javascript
var rooms = {
   "room0": {
       "description": "这里是描述",
       "directions": {
           "direction": "新房间"
       },
       "items": {
           "item1": "物品1",
           "item2": "物品2"
       }
   }
}

因此，我想如果我创建一个名为“items”的单独元素，然后在房间中列出物品，就像我在“directions”中所做的一样。我编写了以下代码将物品添加到玩家的物品栏中：

function grabItem(item) {
   if (inventory.length < 12 && rooms[currentRoom].items[item] !== undefined) {
       inventory.append(item);
       
       //在此处插入代码以从房间中移除物品
   }
}

所以！重要的问题是，我可以使用什么方法来移除单个物品？

I&#39;m exploring how to create a text-based game, and I was tinkering around with moving between rooms. I have this part down and a very elaborate map created where you can type, &quot;go north&quot; etc. The only thing is that the game is very dry, and I wanted to incorporate items. To make the rooms I did this:
```javascript
     var rooms = {
        &quot;room0&quot;:{
               &quot;description&quot;: &quot;description here&quot;,
               &quot;directions&quot;:{
               &quot;direction&quot;: &quot;newRoom&quot;
               }
         }
     }

So, I was thinking if I made a separate element called "items" and then list the items in that room, the way I did with "directions". I wrote this code to add items to the player inventory:

     function grabItem(item){
        if(inventory.length < 12 && rooms[currentRoom].items[item] !== undefined) {
		    inventory.append(item);
		    
            //INSERT CODE HERE TO REMOVE THE ITEM FROM THE ROOM
	    }
      }

SO! The big question is, what method can I use to remove an individual item?

Sure, here's the translated code:

     function grabItem(item){
        if(inventory.length < 12 && rooms[currentRoom].items[item] !== undefined) {
            inventory.append(rooms[currentRoom].items[item]);

            rooms[currentRoom].items[item] = undefined;
        }
      }

     function grabItem(item){
        if(inventory.length < 12 && rooms[currentRoom].items[item] !== undefined) {
            inventory.append(rooms[currentRoom].items[item]);

            rooms[currentRoom].items[item] = undefined;
        }
      }
