In this tutorial, we will walk you through the process of integrating a chatbot into your Unity game using the Eden AI Unity Plugin for AI-powered conversation with non-player characters (NPCs). This integration will add a new layer of interaction, making your game more engaging and dynamic.
Founded in 2004, Unity stands as a prominent gaming company providing a robust game development engine, empowering developers to craft immersive games for diverse platforms, such as mobile devices, consoles, and PCs.
Elevating gameplay is achievable through Unity's capability to seamlessly integrate artificial intelligence (AI), facilitating intelligent behaviors, decision-making processes, and advanced functionalities in your games or applications.
Unity provides various avenues for AI integration. Notably, the Unity Eden AI Plugin seamlessly interfaces with the Eden AI API. This integration streamlines the incorporation of AI features, including AI chatbot functionality, into your Unity applications.
Integrating a non-player character (NPC) AI chatbot into Unity can offer several benefits, enhancing both the development process and the overall gaming experience. Here are some advantages of using a chatbot in Unity:
In summary, incorporating an AI chatbot into Unity adds a layer of interactivity, personalization, and immersion to the gaming experience, contributing to a more dynamic and enjoyable environment for players.
Here are some examples and use cases of chatbots in video games created with Unity:
Dungeon Rushers, a Unity-developed tactical RPG, employs a chat-like interface for in-game communication, enabling players to interact with AI NPCs through text-based conversations. These intelligent NPCs allow players to make decisions that significantly impact the storyline and influence the outcomes of their quests.
In the online survival game Rust, modders have created Unity-based chat systems featuring chatbot functionalities. These chatbots assist players by providing essential information about the game world, facilitating trading, and fostering a more interactive player community.
Plague Inc: Evolved, a strategy simulation game developed in Unity, presents an opportunity for implementing chatbots to drive interactive storytelling. By incorporating chatbot-driven characters, players can engage in dynamic conversations that directly influence the progression of their viral outbreak scenarios.
Astroneer, a space exploration game created with Unity, has the potential to implement chatbots to enhance player communication with in-game AI entities. This includes conversational interactions with intelligent robotic companions, offering guidance, and sharing information about planetary exploration.
Unity-based multiplayer games, such as a Tanks Multiplayer game, can leverage chatbots for team coordination and communication. Chatbots may assist players in strategizing, provide updates on enemy movements, and enhance the overall multiplayer experience through intelligent NPC interactions.
Unity-powered city-building simulations stand to benefit from chatbots simulating civic interactions. Players might engage in text-based conversations with AI-driven citizens, addressing concerns, making decisions, and managing the growth of their virtual cities through interactions with NPC AI chatbots.
In a Unity-created mystery adventure game, chatbots could serve as interactive companions or detectives, aiding players in solving puzzles, providing clues, and adding depth to the narrative through AI-powered conversation with NPCs.
Educational games developed in Unity can integrate chatbots to engage players in learning activities. These chatbots may act as virtual tutors, delivering instructional content, quizzes, and interactive learning experiences in a conversational format with intelligent NPCs.
A Unity-based 2D platformer featuring a branching narrative could leverage chatbots, allowing players to communicate with in-game characters. Conversations with these AI NPCs might significantly influence the storyline, creating a more personalized gaming experience.
These examples highlight the potential use of chatbots in Unity-created video games to enhance player interactions, storytelling, and gameplay dynamics. Unity's flexibility empowers developers to implement chatbot features tailored to the unique requirements of their games, providing a more immersive and intelligent gaming experience.
Ensure that you have a Unity project open and ready for integration. If you haven't installed the Eden AI plugin, follow these steps:
To get started with the Eden AI API, you need to sign up for an account on the Eden AI platform (receive free credits upon registration!).
Once registered, you will get an API key which you will need to use the Eden AI Unity Plugin. You can set it in your script or add a file auth.json to your user folder (path: ~/.edenai (Linux/Mac) or %USERPROFILE%/.edenai/ (Windows)) as follows:
Alternatively, you can pass the API key as a parameter when creating an instance of the EdenAIApi class. If the API key is not provided, it will attempt to read it from the auth.json file in your user folder.
Infuse life into your non-player characters (NPCs) by enabling them to express themselves through the incorporation of chatbot functionality. Utilizing the Eden AI plugin, you can effortlessly incorporate a diverse range of AI Chatbot APIs, including OpenAI, Google and Replicate into your Unity project (see the comprehensive list here).
This feature enables you to customize the model of the engine and behaviour of the assistant, allowing you to tailor the desired ambiance of your game.
Note: The chatbot is designed to provide responses in the same language as the incoming message. The language specification is handled automatically without the need for explicit instructions in the request. For instance, if you send a message in French, the chatbot will respond in French.
The SendChatRequest function returns a ChatResponse response object.
Access the response attributes as needed. For example:
Run your Unity project and test the chatbot functionality. Monitor the console for any potential errors or exceptions and make adjustments as necessary.
Congratulations! Your Unity project is now equipped with a chatbot using the Eden AI plugin. Experiment with optional parameters to fine-tune the chatbot's behavior and enhance the overall gaming experience for your players.
