Godot 4.2 to 4.3 SpineSlotNode SlotName logic changed due to Folder

I want to bring attention to the fact that Godot 4.3 has changed how it detects the Slots in the Spine file. Instead of just the Slot's name, the Slots under a Folder Group are now identified with the Folder Group's name in front (+ "/").

This confused me for a little while and required me to adjust code, but is this format necessary to keep going forward? I find it slightly unnecessary when the Slots need to be uniquely named from each other in the first place.

skarasuko Sorry for the confusion! Actually, it's not due to the version update for Godot, it's due to the change in slot name specification in Spine 4.2 starting with Spine 4.2.21:

Changed slot name uniqueness to the entire path rather than just the name. This affects findSlot at runtime.

This change was made to allow slots to be named more reasonably. For example, with the previous specification, it was not possible to name slots in the following way:

swords/fire
armor/fire

Previously, folder names were not used to determine whether a slot name was unique or not, so names like the one above were determined to be the same as another slot. So you had to name them like this:

swords/sword-fire
armor/armor-fire

It was redundant to have to repeat the same name in this way. So the specification has been changed to judge whether the name is unique or not, including the folder name. This format will be maintained in the future, so we would appreciate it if you could fix your code.
