**Reply by petroslouca | 2024-09-01 22:25:51** I attached the “NarrativeDesignTrigger” on each avatar and created a new game object. Then attached a script with the following function, thus when calling a public function passing to it the required parameters, i.e. I select the AVATAR index number from an array, set it as active and then select the required trigger index again from the hard-coded narrative designer trigger index, I have achieved a simple and efficient opearion as desired: public void AvatarNarrativeTrigger(ConvaiNPC NPCs, int TriggerIndex) { if (NPCs.TryGetComponent(out NarrativeDesignTrigger narrativeDesignTrigger)) {ConvaiNPCManager.Instance.SetActiveConvaiNPC(NPCs); NPCs.isCharacterActive= true; narrativeDesignTrigger.selectedTriggerIndex = TriggerIndex; narrativeDesignTrigger.InvokeSelectedTrigger(); } } ---

**Reply by petroslouca | 2024-09-01 22:33:52** In a strange way, the NPC talks but the text does not always appear on the chatbox! Is there something that should be enabled/triggered to ensure that the NPC’s text appears in the chatbox? ---

**Reply by petroslouca | 2024-09-01 22:34:35** This happens only when performing a narrative trigger. Using the Mic there is no issue. ---
