Interactive LLM Powered NPCs: Revolutionizing Game Interactions
Interactive LLM Powered NPCs is an innovative open-source project that transforms how players interact with non-player characters (NPCs) in video games. Instead of static interactions, this project allows players to engage in realistic, meaningful conversations with NPCs using their microphone.
Overview
The core idea of this project is to allow players to speak directly to NPCs in any game. By incorporating advanced technologies, Interactive LLM Powered NPCs synchronizes lip movements using SadTalker, employs facial recognition to identify distinct characters, and uses vector stores to grant NPCs expansive memory capacity. Pre-conversation files further adjust dialogue styles to match each NPC's unique personality and background. Additionally, a webcam can capture and interpret the player's facial expressions, making interactions even more immersive.
Targeted primarily at popular open-world games like Cyberpunk 2077, Assassin's Creed, and GTA 5, this tool fills a significant void by enabling conversations with any NPC. It aims to enhance the player's gaming experience without any need for modifications to the game's original source code. Instead, it integrates seamlessly by replacing existing facial pixels with generated animations, creating the illusion of natural dialogue.
How It Works
Here's a simplified breakdown of the Interactive LLM Powered NPCs functionality:
- Microphone Input: Players speak through their microphone, and their speech is transcribed into text.
- Facial Recognition: The system utilizes facial recognition to discern which NPC the player is addressing.
- Character Identification: For background NPCs, unique personalities and names are created, while side characters are given access to particular traits and knowledge.
- Large Language Model (LLM) Integration: The model generates responses based on transcribed text, using a vast store of character and world data.
- Pre-Conversation Files: These ensure NPCs maintain authentic dialogue by using pre-existing lines that reflect their speaking style, stored in a pre-conversation.json file.
- Facial Animation and Speech Generation: The response from the LLM is converted into speech, with a corresponding animation video generated to reflect the NPC's face.
- Game Integration: The audio and video are incorporated into the game by overlaying the generated face animation onto the game’s visuals.
- Emotion Recognition: Utilizing a webcam, the system recognizes player emotions, allowing NPCs to adjust their responses to enhance interactivity.
These components enable conversations even during non-visual game moments, such as while on horseback or in combat, without interruptions.
