[Unity, C#, VR] My shot at extending Unity’s own XR Interactions Toolkit capabilities.

After finishing the project for my thesis which is aimed at people with visual impairments I wanted to create an actual game. I decided to once again use Unity’s XR Interaction Toolkit. I started with a character controller which I found to be lacking a lot of functionalities people know from VR games. With help of some tutorials and original source code I created this package. It is still unfinished in a lot of aspects, but it can be imported in Package Manager via git link.

Update 10/02/2024: The XR Interaction Toolkit has changed a lot since this package was created. It now contains features like tunneling vignette and climbing.

Features

1. Movement methods (Locomotion Providers) based on scripts provided in XR Interaction Toolkit (which doesn’t contain all functionalities I wanted).
   • Continuous Movement and Turn with vignette effect (using built-in post process) to help with motion sickness,
   • Snap Turn with blinking (fading screen to black as custom Renderer Feature),
   • Teleportation with blinking and rotation change (rotate the joystick on a controller do determine your final rotation),
   • Climbing,
   • Custom Gravity with floating collider, that allows walking on stairs.
2. Player avatar:
   • based on Rigidbody (for use with Physics) with Capsule Collider which follows player’s height in playspace,
   • Sphere Collider for head (to prevent camera clipping through objects) with support for leaning - player can lean over small obstacles for a certain distance from body.

Potential further development

• extended interactions,
• hands with poses.
