Use "export var
"
Example: export (String) var MemberType
If your scene inherit the script that contains export (String) var MemberType
, then yes this scene will have the option to change the value of this property inside the Inspector, too. (Just put the scene as a child node is not the same as extends its parent class, a script is also a class that extends the class of a node)
If you want a scene to be reused, save this scene. Later you can just load it and instance it, the options you exported will also be there.
