Hi, I’m working on creating an application using Convai NPC. I noticed that I can activate functions through the start and end events in narrative design. However, I haven’t found anything about returning a value. Is it possible for the Convai NPC to return one or more values, allowing me to avoid a more hard-coded approach?

hello \<@1023671043287699568\> sure there it is:
Example: I ask the NPC to recommend a place for holidays, and it suggests “LocationVariable”. Right after, I want to trigger a function in the narrative design section end event and use the “LocationVariable” that the NPC returned. I was wondering if there’s a way to determine a variable directly, or if I need to work around the issue by parsing the strings in the NPC’s response.

\<@1023671043287699568\> Sorry if I’m being too pushy, but I need to know this to structure my next implementation at work. If you can, please respond ASAP.

Unfortunately, you have to find it, but if you want to update the variable dynamically you can check our Narrative Design Keys,
