Relating to https://www.factorio.com/blog/post/fff-402. When using set_blueprint_entities, even without modifying anything, it forgets those wire connectiong going to external entities.

Code: Select all

script.on_event(defines.events.on_player_setup_blueprint, function(event)
	local item = event.record or event.stack
	item.set_blueprint_entities(item.get_blueprint_entities())
end)

Can we have the possibility to read and preserve those outgoing connections when using the cut tool?

Thanks for the report however when you do what you’re doing you are functionally deleting and re-creating the entire blueprint. The game has no way to know the entities you replaced the contents with are “the same”.

As for reading the external connections, that can likely be done through a new API, but would go into modding interface requests.
