This is the video. The error at the beginning is a NullReferenceException: Object reference not set to an instance of an object. The error that appears later occurs when I press the action key.

Will that affect the usage?

Is there any way to call a trigger? Also, if I want the trigger to initiate a conversation, how should the function be written, or what variables should I check?

Thank you!

Hello <@807630326666362931> 
,
Did you make any changes to the current Convai scripts?

I tried writing a function myself to call the trigger, and in the second picture, the photos send back the conversation between the user and the NPC, turning it into a dialogue. Previously, I also attempted to directly call InvokeSelectedTrigger within the NarrativeDesignTrigger class by passing in the trigger name.

No, just when you invoke the trigger (by any unity runtime), it would call it on the appropriate NPC, which has the trigger assigned. Won’t give any error, there are quite a few changes in doing so, you can wait till release, or if you want to do it yourself, you can reference the correct NPC

So currently, can triggers only be called using collision, or is there another method? Or can I directly pass the trigger name when calling, like in my function? Also, could you tell me where the variable that confirms the connection status is? I’d like to use it. Thank you!

You can use the npc to invoke it, like _currentnpc.invoketrigger but it would require exact name. Our design right now is scene specific as it makes more sense to narration to flow that way, but you can call it otherwise.

I can’t understand which connection or variable you want?

Sorry, I made a mistake. I don’t need that variable to check the connection status. So, does the trigger have a similar usage? This is what I used before in Inworld. Or, as you mentioned, using _currentnpc.invoketrigger. Do you have a more specific example? Thanks!

Hi, I’m just reading all this because I’m trying to do exactly the same!

<@807630326666362931> I also noticed that in the demo of NPC to NPC the characters start talking to one another without the player needing to talk first. Reading the scripts that control them could be useful.

Hello <@807630326666362931>, <@328311427980984322>
Please import “InitializeConversation.cs”
Then open NarrativeDesignTrigger, replace the InvokeSelectedTrigger method with this one.
public void InvokeSelectedTrigger()
{
if (convaiNPC != null && availableTriggers != null && selectedTriggerIndex >= 0 && selectedTriggerIndex < availableTriggers.Count)
{
string selectedTriggerName = availableTriggers[selectedTriggerIndex];
ConvaiNPCManager.Instance.SetActiveConvaiNPC(convaiNPC,false);
convaiNPC.TriggerEvent(selectedTriggerName);
Debug.Log($"Triggered {selectedTriggerName} on {convaiNPC.name}");
}
}
Finally, the SetActiveConvaiNPC method of ConvaiNPCManager.cs is replaced with this one.
public void SetActiveConvaiNPC(ConvaiNPC newActiveNPC, bool updateLastHitNPC = true)
{
if (activeConvaiNPC != newActiveNPC)
{
if (activeConvaiNPC != null)
// Deactivate the previous NPC
activeConvaiNPC.isCharacterActive = false;
activeConvaiNPC = newActiveNPC;
if(updateLastHitNPC)
_lastHitNpc = newActiveNPC;
if (newActiveNPC != null)
{
// Activate the new NPC
newActiveNPC.isCharacterActive = true;
Debug.Log($"Active NPC changed to {newActiveNPC.gameObject.name}");
}
OnActiveNPCChanged?.Invoke(newActiveNPC);
}
}

Hello <@1023671043287699568> thank you so much for the answer and the code! I’ve been adding everything and testing it. It works until this point:
Reply by hiimabiel | 2024-08-27 18:25:16
There seems to be an error with the return client.GetResponse(options);
method under the ConvaiGRPCAPI.cs script. I’m trying to make my NPC have a monologue and then react to when the player talks to him
