Hello, I am working on Narrative Design in Convai and trying to implement it in Unity. I want to evoke a trigger that activates when a specific ‘event’ occurs, not just when entering a certain space. However, I can’t figure out how to do this. How can I achieve this? I apologize if my writing is unclear, as I’m not very good at English. Thank you.

Im sure documentation had somthing similar to the three types of triggers it talked about.  
But if you arent able to work with that then u can use a similar solution i posted to my problem and u can alter it such that when that certain `event` occurs, there should be a prompt sent to the NPC and you can alter the narrative design part of the NPC from playground such that when that specific prompt is being recieved by the NPC, it should behave to however you want the NPC tobehave when that event occurs

It is up to you to customize this.

The basic logic is to call the Invoke SelectedTrigger function of narrativeDesignTrigger when an event occurs.

Thank you. I want to evoke a trigger when a specific event occurs. In that case, should I add the method to the script of that event?

I tried it as you suggested, but I encountered the following error.

“The type or namespace name ‘NarrativeDesignTrigger’ could not be found (are you missing a using directive or an assembly reference?)”

In fact, I had previously tried the same method because the Convai documentation provided a similar code, but I got the same error back then, which is why I ended up asking for help here 😦 How can I resolve this?

The type or namespace name ‘Features’ does not exist in the namespace ‘Convai.Scripts.Runtime’ (are you missing an assembly reference?)

This time, this error has occured. I’m so sorry for asking so many questions.😥
