UdonSharp (Muni's version)

This is my maintained fork of Merlin's UdonSharp, based on the VRChat Worlds SDK integration. I'm trying to keep this repo updated because:

• VRChat doesn't seem to be adding support for Collections in their bundled UdonSharp.
• Merlin doesn't seem to be actively updating his upstream repo either.

My goal is feature parity with VRChat's shipped UdonSharp while also having:

• Collections support (e.g. List<T>, dictionaries, and related APIs where the compiler allows them).
• Access to non-UdonSharp Unity / VRChat types where appropriate for world development.

There are no formal releases here — I use this repo directly in my own projects. I'll try to fix bugs and keep things working when I can; if something breaks, open an issue on this repo. That said, this is a personal fork — use at your own risk, and please don't blame me if it breaks your project.

For problems with VRChat's bundled UdonSharp or the Worlds SDK itself, take it up with VRChat (support, feedback, Canny, etc.) — their public community repo for UdonSharp isn't kept up to date either.

Installation

Make a backup of your project first. If Unity mishandles importing packages like this, things can go badly wrong.

1. Close your Unity project.
2. Confirm your project is backed up.
3. Go to Packages/com.vrchat.worlds/Integrations and delete the UdonSharp folder and its UdonSharp.meta file (VRChat's bundled copy).
4. Download this repository (clone or "Download ZIP" from GitHub — use the full source, not random assets GitHub might list elsewhere).
5. Copy the Packages/com.merlin.UdonSharp folder from this repo into the Packages directory of your Unity project (merge/replace if you already had an older copy).
6. Open your project again. If everything imported cleanly, it should behave like before, with the updated compiler and features from this fork.
