Prerequisites

Before we begin, make sure you have the following:

• SteamVR plugin installed in Unity (we’ll cover this in the next step)
• A SteamVR-compatible headset (e.g., HTC Vive, Oculus Rift, etc.)
• A decent computer that meets the system requirements for SteamVR

Installing the SteamVR Plugin

If you haven’t already, install the SteamVR plugin in Unity. Here’s how:

1. Open Unity Hub and create a new project or open an existing one.
2. In the Unity editor, navigate to Window > Package Manager.
3. In the Package Manager window, click the + icon at the top-right corner.

Configuring the SteamVR Plugin

Now that we have the plugin installed, let’s configure it:

2. In the XR Settings window, select SteamVR as the Target Device.
3. Under SteamVR Settings, make sure the following options are enabled:
• Enable SteamVR
• Use SteamVR Camera Rig
• Use SteamVR Tracking System

Setting Up the Camera Rig

The camera rig is crucial for a smooth VR experience. Here’s how to set it up:

1. In the Hierarchy panel, right-click and select SteamVR > Camera Rig.
2. Name the new camera rig “SteamVRCameraRig” (or any name you prefer).
3. Drag and drop the SteamVRCameraRig into the scene.
4. In the Inspector panel, set the Camera Type to SteamVR Camera.

Setting Up the Tracking System

The tracking system allows SteamVR to track the user’s head movements. Here’s how to set it up:

1. In the Hierarchy panel, right-click and select SteamVR > Tracking System.
2. Name the new tracking system “SteamVRTrackingSystem” (or any name you prefer).
3. Drag and drop the SteamVRTrackingSystem into the scene.
4. In the Inspector panel, set the Tracking System Type to SteamVR Tracking System.

Adding Controllers

Controllers are essential for interacting with the virtual environment. Here’s how to add them:

1. In the Hierarchy panel, right-click and select SteamVR > Controller (Left).
2. Name the new controller “SteamVRLeftController” (or any name you prefer).
3. Drag and drop the SteamVRLeftController into the scene.
4. Repeat the process for the right controller.

Configuring the Scene

Now that we have the plugin configured, let’s set up the scene:

1. Create a new scene or open an existing one.
2. Add a SteamVR Camera Rig to the scene (we created this earlier).
3. Add a SteamVR Tracking System to the scene (we created this earlier).
4. Add the SteamVRLeftController and SteamVRRightController to the scene (we created these earlier).

Adding a VR-Ready Character

A VR-ready character is essential for a immersive experience. Here’s how to add one:

1. Create a new game object or use an existing one.
2. Add a SteamVRCharacterController component to the game object.
3. Configure the character controller as desired (e.g., set the movement speed, etc.).

Building and Running the Scene

Now that we have the scene set up, let’s build and run it:

1. Go to File > Build Settings.
2. In the Build Settings window, select the SteamVR target.
3. Click Build to build the scene.
4. Open the built scene in SteamVR.
5. Put on your VR headset and enjoy the experience!
