Introduction

In this tutorial, we will guide You on how to add an AI character to your VR Chat world. Adding AI can enhance the interactivity and realism of your virtual environment. We will walk you through the step-by-step process of setting up and configuring a simple AI using the VR Chat Creator tool and Udon Sharp.

Setting Up VR Chat Creator Tool and Udon Sharp

Before we begin, you will need to have the VR Chat Creator tool and Udon Sharp installed on your computer. These tools are necessary for creating and scripting interactive elements in VR Chat. Make sure you have the latest versions of both tools.

Installing the Simple AI

To add an AI character to your VR Chat world, you will first need to download the Simple AI Package. We will provide a link in the description of this tutorial. Once you have downloaded the package, import it into your project by double-clicking on it or using the import function.

Placing the AI in Your World

After importing the Simple AI package, you need to Create an empty object in your scene. This object will serve as the container for your AI character. Place the Simple AI prefab into your scene and ensure that it is not clipping through the floor.

Configuring the AI's Movement

To enable the AI character to navigate through your world, open the Window menu and select AI. This will open the AI Navigation pane. In this pane, click on the Object button and toggle the option to enable navigation for the AI object. This will define the area within which the AI character will move.

Customizing the AI's Appearance

Now that the AI character is in the scene and set up for movement, we can customize its appearance. If you have a specific Avatar you want to use for the AI, go to the Assets menu, select the avatar, and drag it into the scene. Align the AI character and the avatar to make the customization process easier.

Setting Up the Walking Animation

By default, the Simple AI package comes with a basic walking animation. However, this animation may not be suitable for your AI character. To change the walking animation, you will need to download a new animation that matches the movement style you desire. We will provide a download link for a walking animation in the description of this tutorial. Once downloaded, Apply the walking animation to the AI character.

Adding Sitting Animation

In addition to walking, you may also want to add a sitting animation to your AI character. To do this, you will need to obtain a sitting animation and apply it to the AI character in the same way as the walking animation. Ensure that the AI character is positioned correctly and that the sitting animation is playing smoothly.

Testing the AI's Movements

To test the AI character's movements, click on the Play button in the Unity editor. The AI character should start walking within the defined navigation area. Ensure that the AI character is moving as expected and that it interacts with the environment appropriately.

Conclusion

Congratulations! You have successfully added an AI character to your VR Chat world. We have covered the step-by-step process of setting up the AI using the VR Chat Creator tool and Udon Sharp. Feel free to customize and experiment with different animations and configurations to create a unique interactive experience in your virtual world.
