Thanks for the feedbacks!
I quickly checked and it seems to work with AnimBP, but I need to test it further.
I don’t have any plan to directly integrate it to Behavior Trees as it is quite different from BP, but you can still make bridges from BT to BP and then use any variable/condition in the dialogue branching.
Maybe things will be clearer when I release the update for executing the dialogue. Until now, I’ve only been working on the dialogue design, which is stored in a Dialogue object. It should be out soon, but it’s quite a bit of work too.
