Blueprint Dialogue System

No worries!

The file I mentioned (BP_DIalogueSample_PlayerController) implements the DialogueAware interface which has the DialogueOpened/Closed events. Those events pass along a reference to the dialogue UI, so you can keep it in a variable on your player controller. In the sample, I only use those events to set a flag of viewing an interface or not, but in your case, you’ll want to store a reference to the interface so that you can interact with it.
