InstanceBehavior - How does it work?

[JulianEgbert]

In the InstanceBehavior we have the functions create_instance(), update_scene() and maybe_update_scene() which are all public (visible). To my undestanding this node is primarily used within the editor and not during runtime. Therefore connections to this node shouldn't be possible?! Maybe I also just don't understand this Behavior because we haven't used it before...

Documentation is present in the README and I see the point of copying stuff with this. I don't see yet, how I can trigger the update_scene method though. Maybe the code needs better comments in order to understand what it does?

Indeed, it does not have runtime any significance or API. You would select the behavior, hover its connection menu, and press the special instantiate button at the menu's top.

[JulianEgbert]

But how do you call the other functions? There is only one button. Or are they called automatically?

[tom95]

Yes, they are all called by various callbacks :)

create_instance when the button in the menu is pressed.
maybe_update when the scene is saved.
update when from maybe_update, if the saved scene is our scene.
