我试图弄清你的问题，但不幸的是，我无法做到，可能是因为自动翻译没有发挥作用。让我确认一下以下几点。
你是否打算更换附件（行李的内容）在运行时完成？
如果是这样，你能告诉我们你使用的是哪种运行时吗？
你说的 "元素图片"，是指行李箱内有多个Spine骨架吗？
I tried to figure out your problem, but unfortunately I couldn't, probably because the automatic translation didn't work. Let me make sure the following:
Do you plan to replace the attachment (the contents of luggage) to be done at runtime?
If so, could you tell us which runtime you are using?
By "split element pieces", do you mean that there are multiple Spine skeletons inside the luggage?
