In this tutorial I go over several different ways you can connect a widget blueprint to a blueprint actor.

Chapters:

• 00:00 Intro
• 00:35 Set Up Widget Blueprint and Actor Blueprint.
• 08:27 Connect via a Event Dispatch.
• 13:45 Direct Communication.
• 16:42 Interface.

I use a simple example of how to connect a button from a widget to turn off a light in a separate blueprint. I cover how to use an event dispatch and cast. Direct communications and also how to use an Interface. Whilst I use an example of turning a light on and off with a widget button. The same principles can be used to various functionality and many other actions (e.g. open a door, set off an explosion, trigger an event etc…)

In the tutorial I do mention about creating comments, but forgot to say how. To do this you simply can select a node or nodes and Press C to comment them.
