AI NPC

This guide shows how to create AI-driven NPCs using the NAREON system. We'll set up a personality profile, manage states, and generate dialogue.

1. Extending NAREONAgent

Create a script, for example MyPersonalityNPC.cs:

using UnityEngine;
using NAREON;
using System.Collections.Generic;

public class MyPersonalityNPC : NAREONAgent
{
    void Start()
    {
        var profile = new PersonalityProfile
        {
            Name = "Aria the Bard",
            CoreTraits = new[] { "Cheerful", "Brave", "Curious" },
            MoodThresholds = new Dictionary<Mood, float>
            {
                { Mood.Happy, 0.8f },
                { Mood.Anxious, 0.2f }
            },
            Ideals = new[] { "Protect the weak", "Seek adventure" },
            Flaws  = new[] { "Impulsive", "Over-trusting" }
        };

        SetupPersonality(profile);
        // Optional: LoadBehaviorTree("Assets/BehaviorTrees/BardBehavior.asset");
        RunAI();
    }

    public string RespondToPlayer(string playerPrompt)
    {
        // This calls NAREONAI.SendConversationPrompt internally,
        // which uses the configured AI model (OpenAI/Claude/Llama).
        return GenerateDialogue(playerPrompt);
    }
}

1. SetupPersonality(...) sets custom traits, ideals, or moods.

2. GenerateDialogue(...) requests an AI-generated response (assuming you called NAREONAI.ConfigureOpenAI(...) or similar earlier).

2. Dialogue Example

A simple interaction script:

csharpCopyusing UnityEngine;

public class NPCDialogueTrigger : MonoBehaviour
{
    public MyPersonalityNPC npc;

    public void PlayerTalks()
    {
        string playerText = "Hello Aria, any stories to share?";
        string npcReply = npc.RespondToPlayer(playerText);
        Debug.Log($"[NPC]: {npcReply}");
    }
}

Attach NPCDialogueTrigger to an in-game object, reference the MyPersonalityNPC component in the Inspector, and call PlayerTalks() via a button or event.

3. Combining with Behavior Trees

If you have a custom Behavior Tree solution, you can:

• Load the asset in Start() with LoadBehaviorTree(path).

• The NPC might adapt its state or dialogue based on mood, trait checks, or triggers.
