Do you have this scene ready in any example, or would you need to prepare it? If you have something ready, it could be nice so I can compare how it works with my current implementation. It might be faster. But only if you already have something ready, no need to create something specific for me.
In any case, I'll be preparing a version to send to you anyway
Are you running multiple simultaneous conversations?
If Require Continue On Last Line is the only thing that shows the continue button, then it should only appear when the current conversation state doesn't link to any other valid nodes. So maybe something else is making the continue button appear.
Would it be possible for you to send a reproduction project to tony (at) pixelcrushers.com?
Thanks for sending the repro project. I sent you a patch. The change will also be in DS version 2.2.50. (It resets the SMSDialogueUI's shouldShowContinueButton bool when the UI closes.)
The patch you sent me worked perfectly. I'm glad that this change will be included in an update of the Dialogue System, and I hope it will help others as well.
