Hello,
could you please provide a simple example in the case that there are more than one NPC’s in a Unity3D scene, on how to invoke a specific narrative trigger included in the narrative design of one of the NPCs, using a script that is attached to a new/empty game object?

Thank you!

I downloaded it from asset store and installed it a couple of weeks ago.

Is this a new project?

I have been already working on a VR project using XRI toolkit 2.5.2

Add,

  • NarrativeDesignManager
  • NarrativeDesignTrigger components to your NPC.

There are two ways,
First we can call a trigger on ConvaiNPC or create a new script.
If you use the ConvaiNpc Method, it will affect all NPCs.

In ConvaiNPC or New Script, add this code to the Start method.

if (TryGetComponent(out NarrativeDesignTrigger narrativeDesignTrigger))
  {
    narrativeDesignTrigger.InvokeSelectedTrigger();
  }

You mean inside a publicly accesible function?

What do you mean

I prefer a new script so as not modify any code in the original scripts.

So, create a new Gameobject with a script like the following attached to it:

using Convai.Scripts.Narrative_Design;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Convai.Scripts.Utils;
using Convai.Scripts;

public class NarrativeDesignManualTrigger : MonoBehaviour
{
[Header(“AVATAR MEDIEVAL OUTLANDER DATA”)]
[Tooltip(“CONVai NPC”)]
public ConvaiNPC convaiNPC_MedievalOutlander;
//[Tooltip(“CONVai NPC GO for accessing the collider’s radius”)]
//public GameObject convaiNPC_MedievalOutlander_GO;

// Start is called before the first frame update
void Start()
{
    convaiNPC_MedievalOutlander = GetComponent<ConvaiNPC>();
}

public void WelcomeTrigger()
{
    ConvaiNPCManager.Instance.SetActiveConvaiNPC(convaiNPC_MedievalOutlander);

    if (convaiNPC_MedievalOutlander.TryGetComponent(out NarrativeDesignTrigger narrativeDesignTrigger))
    {            narrativeDesignTrigger.InvokeSelectedTrigger();
    }
}

}

Is this approach right?

It is important to have the avatar talking even if not directly having the user’s crosshair on it, as I understand that narrative trigger can be used to have the avatar acting/talking on a user’s event, e.g. approaching a specific game object.

Could you provide additional reousrces to the documentation (Adding Narrative Design to your Character | Documentation) for a more detailed information about invoking triggers from a script? An online video (YouTube) specifically on this aspect, would be really helpful!
