If you need to parse member-variables into a text in Unreal Editor (for example, when editing some stats that are reflected in text) you can use StringParseTool header!
Create a derived from StringParseTool BP that has three pointers to the objects, which are derived classes from MyObjejct — set them to pointers you want and change Description: resulting string will be in DescriptionPreview field.
See Task, and 3 objects: ExampleObject1, ExampleObject2, ExampleObject3 Task points to!
