Creating a Smart NPC from Scratch

Creating a smart Non-Player Character (NPC) from scratch allows for an interactive and engaging gaming experience. By utilizing chat GPT, the NPC can answer and respond to the questions asked by the player. This article will guide You through the step-by-step process of creating a smart NPC using chat GPT technology.

To start the process, visit confai.com and sign up for an account. Creating an account will enable you to design and customize the behavior of your AI.

Designing the AI Character

Once you have created an account, access the dashboard and select "Create New Character." Here, you will have the opportunity to name your AI character and choose its voice. You can also write the backstory for your character manually, or save time by using chat GPT to generate a backstory based on a provided prompt.

Using Chat GPT to Write the Backstory

To save time, use chat GPT to generate the backstory for your AI character. Simply provide the prompt and let chat GPT generate a suitable backstory. Copy the generated text and paste it into the character's backstory field. Additionally, customize the name of your character based on the generated text.

Installing the conf AI Plugin in Unreal Engine

To integrate the smart NPC into your game, navigate to the Unreal Engine Marketplace and search for "conf AI". Download and install the conf AI plugin compatible with your Unreal Engine version. Activate the conf AI plugin in your project by going to "Edit" and selecting "Plugins". Restart the editor to ensure the plugin is enabled.

Enabling Voice Chat with the AI

To enable voice chat with the AI, make a configuration change in the project files. Access the content drawer, right-click, and select "Show in Explorer". Locate the project's config folder and open the "DefaultEngine.ini" file. Add the necessary lines of code provided in the article. Save the file and restart your project for the changes to take effect.

Setting Up the Player Character

To establish the player character as the conf AI base player, open the player character blueprint and go to "Class Settings". Change the parent class to "conf AI base player". Save the changes to the blueprint.

Adding a Meta Human to the Project

A meta human will serve as the visual representation of your NPC in the game. Quickly add a meta human to your project by selecting "Quickly Add to Project" and navigating to "Meta Humans". Choose a suitable meta human and enable any missing plugins during the addition process. Restart the editor to ensure the plugins are activated.

Resolving Warning Messages in the Meta Human Blueprint

After adding the meta human to your project, you may encounter warning messages in the blueprint. Resolve these warnings by modifying the blueprint. Look for instances of the warning and replace them with the appropriate function or asset. Repeat this process for all warning instances.

Compiling and Configuring the Meta Human

Configure the meta human blueprint settings to ensure compatibility with the conf AI system. Change the parent class to "conf AI based character" in the class settings. Set the animation classes for the meta human's face and body to the appropriate conf AI animation classes. Compile the blueprint and save the changes.

Configuring the API Key and Character ID

To establish a connection between your project and the online conf AI account, configure the API key and character ID. Go to "Edit" and select "Project Settings". Scroll down to find the "conf AI" plugin and enter your API key. Obtain the API key from your conf AI online account. Copy and paste the character ID of your AI character into the corresponding field. Save the settings.

Testing the AI

After configuring all the necessary settings, you can now test the AI. Initiate voice chat by pressing and holding the designated button and ask your AI character questions. Engage in conversation and witness the AI's ability to respond and Interact.
