AI NPCs in the Metaverse
What is NPC?
A non-player character (NPC) or a non-playable character is a character in a computer game that does not receive input from a human player. An NPC operates according to a set of instructions or rules that are programmed by the game developer. These instructions or rules specify the behavior, reaction, and interaction of the NPC with the game environment and other characters. Traditional NPCs tend to repeat the same actions and dialogues every time, and they may engage with the player character or other NPCs in various ways. NPCs can play different roles in games that enhance the player experience throughout the gameplay.
Generative AI is a type of artificial intelligence technology that can create new content, such as text, images, code, or other types of data, based on the data it has learned. Generative AI uses machine learning techniques, such as neural networks and deep learning, to analyze patterns and relationships in large datasets and then generate new outputs that are similar or related to the original data. Generative AI can be used to create AI NPCs that can generate natural language texts for various game scenarios and characters, based on a given input or context. By using generative AI, game developers can create more realistic and immersive experiences that leverage natural language interactions with characters. Generative AI can also enable game users to explore new genres and narratives that are not limited by predefined scripts or rules.
AI NPC is a newly added term to non-player characters (NPCs) in games that use artificial intelligence (AI) to generate natural language interactions with players. AI NPC is a novel and emerging technology that aims to enhance the realism and immersion of games by creating lifelike and dynamic conversations with game characters. AI NPC works by using large language models (LLMs) to generate natural language texts based on a given input or context. LLMs are neural networks that can learn from large amounts of text data and produce coherent and relevant texts for various tasks and domains. To implement AI NPC using LLMs some input or context for the LLM to generate texts for the characters are needed. The input or context can be a prompt, a question, a keyword, a dialogue history, or any other information that guides the LLM to produce texts that are relevant and appropriate for the game scenario and character. It can also be customizable by fine-tuning it on specific data sets or adding some rules or constraints to control the output of the LLM. By using AI NPCs can create more engaging and personalized metaverse experiences, as well as explore new genres and narratives that leverage natural language interactions.
