No entity_type meta data in dropable_control in mobfactioneditor

[snipercup]

In the mobfactions_editor.gd in the _on_save_button_button_up function it will complain that the dropable_control has no meta data of entity_type.

To fix this:
Go to add_relation_type function and add this line:
var entity_type: String = "mob" if relation.has("mob") else "mobgroup" if relation.has("mobgroup") else ""

And this line:
dropable_textedit_instance.set_meta("entity_type", entity_type)

So it looks like this:

func add_relation_type(relation: Dictionary) -> HBoxContainer:
	var hbox = HBoxContainer.new()

	# Add the label
	var label_instance: Label = Label.new()
	label_instance.text = "Relation type:"
	hbox.add_child(label_instance)

	# Add the dropable text edit for the mob or mobgroup ID
	var entity_type: String = "mob" if relation.has("mob") else "mobgroup" if relation.has("mobgroup") else ""
	var dropable_textedit_instance: HBoxContainer = dropabletextedit.instantiate()
	dropable_textedit_instance.set_text(relation.get("mob", relation.get("mobgroup", "")))
	dropable_textedit_instance.set_meta("entity_type", entity_type)
	dropable_textedit_instance.set_meta("relation_type", relation.get("relation_type"))
	dropable_textedit_instance.myplaceholdertext = "Drop a mob or mobgroup from the left menu"
	set_drop_functions(dropable_textedit_instance)
	hbox.add_child(dropable_textedit_instance)
	return hbox
