Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

How it works...

When specifying UPROPERTY, we can indicate where we want that value to be available inside the Unreal editor.

Visible* prefixes indicate that the value is viewable in the Details panel for the indicated object. The value won't be editable, however.

This doesn't mean that the variable is a const qualifier; however, native code can change the value, for instance.

Edit* prefixes indicate that the property can be altered within the Details panels inside the editor.

InstanceOnly as a suffix indicates that the property will only be displayed in the Details panels for instances of your class that have been placed into the game. They won't be visible in the Class Defaults section of the Blueprint editor, for example.
