我需要完成几项任务，我需要一些指导。
首先，我必须使用T命令，允许玩家获取他们所在的当前房间中的项目。每个房间的项目都在各自的Locale阵列中。通过使用itemPresent，它将获取player1当前房间最初设置的项目，并且整个游戏中的房间不会更新，而是在move（）方法中更新。我想使用roomData [2]以这种方式获取项目，但由于我无法从另一种方法中获取变量，因此我无法执行此操作。那么，我怎么能从当前房间拿走这件物品呢？
其次，我需要在拍摄后将物品从房间中取出，以便物品不能被拍两次。
第三，我必须将此项目添加到我尝试使用ArrayList设置的玩家库存中。我不确定如何设置代码，以便我可以获取刚刚找到的项目并将其添加到库存中。
感谢您的帮助!!
