Introduction

In this article, we will explore the fascinating world of creating more Context over NPCs with programming your prompts. We'll Show you some tricks to get responses from NPCs that your game can use and react to. By adding components and logic to your prompts, we can Create more flexible and context-aware interactions with NPCs. This has the potential to make your game feel more immersive and interactive. So let's dive in and see what we can do!

Setting up the Project

Before we begin, let's set up the project. In this tutorial, we will be using the OpenAI Package, the Ready Player Me SDK, and Unity's third-person starter assets. If You're not familiar with these tools, don't worry - we will walk you through the installation and setup process step by step. By the end of this section, you'll have everything you need to start creating more engaging and dynamic NPCs in your game.

Creating the World Info Component

The first component we will create is called World Info. This component will hold important information about the game world, including the game story and the location. By providing this context to NPCs, they can respond to questions and events in a Meaningful way. We will walk you through the process of creating this component, setting up the necessary fields, and attaching it to your game objects. Additionally, we will discuss how to use the Text Area attribute to improve the visibility and usability of the World Info component in the Unity editor.

Adding NPC Information

In order to create more context-aware NPCs, we need to provide them with additional information. This includes attributes like name, occupation, talents, and personality. By giving NPCs these characteristics, they can tailor their responses to match their individual traits. For example, a taxi driver NPC might have knowledge about cars and driving, while a bank accountant NPC might have expertise in financial matters. We will show you how to create a new component called NPC Info and populate it with the necessary fields. Additionally, we will discuss the use of enumerators to ensure consistent and structured data entry for occupations, talents, and personality types.

Generating Prompts for the NPCs

Once we have set up the necessary components and provided NPC information, we can start generating prompts for the NPCs. These prompts will determine how the NPCs respond to specific questions or events. We will explore the use of the Chat GPT package to generate prompts Based on the provided context. By combining the prompts from World Info and NPC Info, we can create more dynamic and context-aware conversations. We will show you how to modify the existing scripts and create a new branch in GitHub to keep track of the changes. Additionally, we will discuss the importance of adjusting the temperature value and using appropriate phrases to indicate the end of a conversation.

Implementing Conversations

Now that we have generated our prompts, it's time to implement the conversations between the player and the NPCs. We will guide you through the process of creating a dialogue system that allows for seamless back-and-forth conversations. By using the Adventure and NPC prompts, we can simulate a conversation between two characters. We will show you how to handle user input, trigger NPC responses, and format the dialogue for easy readability. Additionally, we will discuss the concept of "context switching" and how it affects the flow of the conversation.

Ending the Conversation

In order to provide a more natural and immersive experience, we want to give the player the ability to end the conversation at any time. We will show you how to add a phrase to indicate the end of the conversation and trigger the corresponding action. By identifying specific keywords or phrases in the NPC's response, we can automatically close the dialogue panel and return to the game. We will walk you through the implementation of this feature and discuss the importance of testing and refining the conversation flow.

Advanced Prompts and Actions

To further enhance the interaction with NPCs, we can leverage the power of advanced prompts and actions. This allows us to program certain phrases or keywords to trigger specific events or behaviors in the game. For example, we can create a prompt that detects if the player asks about a certain topic and responds accordingly. We will discuss how to add these advanced prompts and actions to the dialogue system and explore the possibilities they offer for creating more dynamic and immersive gameplay experiences.

Testing and Experimentation

Throughout this tutorial, we encourage you to test and experiment with different prompts, actions, and dialogue flows. By iteratively refining and expanding the NPC's knowledge base, you can create more realistic and engaging conversations. We will provide tips and suggestions on how to test and iterate on your dialogue system, as well as highlight the importance of considering player feedback and incorporating improvements based on user experience.

Conclusion

In this article, we explored the world of creating context-aware NPCs through programming prompts. We discussed the importance of providing meaningful context to NPCs, generating prompts based on the provided context, and implementing dynamic conversations between the player and NPCs. We also explored advanced prompts and actions, as well as techniques for ending the conversation and testing and refining the dialogue system. By following the steps outlined in this tutorial, you can create more immersive and interactive gameplay experiences with your NPCs. We hope you found this article helpful and inspiring. Happy NPC programming!
