Is this the correct way to have looping dialogue?

[AoF]

I want to have a "hub" that the conversation keeps going back to so that you can select new choices. I tried it the naive way, and the problem was that the NPC kept on saying the line that got you there over and over again. So instead, I created a child node that says nothing and only has a continue(), and now I have the conversations point back to that. Am I doing this the right way, or is there a better way?

That will work, but the better way is to tick the "hub" node's Group checkbox.

Ah, so the only thing that does is save me from writing Continue() in the sequence, right? I see that as better, I just want to make sure I'm not missing some other benefit if there is one.

[Tony Li]

That's correct.
