重命名节点时调用功能？
非常简单的Q，当节点重命名时，如何调用功能？
我认为可能会调用_SET（）函数，但它不起作用用于重命名
pretty straight forward Q, How do I invoke a function when the node is renamed?
I thought maybe _set() function would be invoked but it doesn't work for renaming

从编辑器旁路设置
名称_SET（）。您可以使用_SET（）从代码设置name时进行拦截。另一个选项是连接
“重命名”信号（所有nodes都有它）。您可以在
_Init的情况下尽早连接，如果您希望在任何代码进行任何node的任何代码之前都可以更改其名称。但是，这仅在场景树内的
节点时触发。最后，一种检测
名称更改的方法，无论更改如何是聆听notification_path_changedNotification。您在
_notification默认情况下获得notification_path_changed，无需启用它或类似的东西。当
节点不在场景树中时，它甚至可以工作，我发现这令人惊讶。更令人惊讶的是，它在将
节点添加到场景树时不会触发，或将其删除（这些是notification_enter_tree和notification_exit_tree分别） ，尽管这些动作改变了节点的路径。因此，我相信notification_path_changed是错误的称呼，应该是“ notification_name_changed”。附录：在Godot 4上，它被更名为
notification_path_renamed。Setting the
namefrom the editor bypasses_set(). You can use_set()for intercepting when you set thenamefrom code.Another option is to connect the
"Renamed"signal (allNodes have it).You can connect as early as
_initif you want it to happen before whatever code is instancing theNodehas a chance to change its name.However, this one only triggers if the
Nodeis inside the scene tree.And, finally, a way to detect changes of
nameregardless of how the change happens is to listen for theNOTIFICATION_PATH_CHANGEDnotification.You get
NOTIFICATION_PATH_CHANGEDin_notificationby default, no need to enable it or anything like that.It even works when the
Nodeis not in the scene tree, which I find surprising.Even more surprising, it does not trigger when adding the
Nodeto the scene tree, or removing it (those would beNOTIFICATION_ENTER_TREEandNOTIFICATION_EXIT_TREErespectively), despite those actions changing the path the node. So I believeNOTIFICATION_PATH_CHANGEDis a misnomer, it should be "NOTIFICATION_NAME_CHANGED".Addendum: On Godot 4 it was renamed to
NOTIFICATION_PATH_RENAMED.
