Hello all! I’m working on a plugin for Unreal and I was wondering if there is a way have code execute when the save button is pressed in the blueprint editor? This would save me a lot of time as I would rather not create a new editor that does what blueprint does. Thank you! 
A quick search shows that this code gets executed:
File: Source\Editor\Kismet\Private\BlueprintEditor.cpp
Function: FBlueprintEditor::SaveAsset_Execute
I don’t see a way to hook into this event without changing the engine code. Maybe it’s possible through some other way
You can add a new button to the toolbar of the blueprint window using Toolbar Extenders. Let me know if you need help with this
