An attribute you can add to code to expose properties in UEFN. Tagging code with this attribute consists of adding an @attribute_name (in this case @editable) before a field identifier:
Verse
@editable
PropertyName : type = DefaultValueFor example, the string field GreetingMessage is an editable property with the default value "Hello, stranger":
Verse
expose_properties := class(creative_device):
@editable
GreetingMessage : string = "Hello, stranger"For more on how to use this, see Customize Your Device Properties in the Editor.
