unity-vrc-udon-sharp

/unity-vrc-udon-sharp

UdonSharp (C# to Udon Assembly) scripting skill for VRChat world development. Use this skill when writing, reviewing, or debugging UdonSharp C# code. Covers compile constraints (List<T>/async/await/try/catch/LINQ blocked), network sync (UdonSynced, RequestSerialization, FieldChangeCallback, NetworkCallable), persistence (PlayerData/PlayerObject), Dynamics (PhysBones, Contacts), Web Loading, VRAM management (texture lifecycle, Dispose vs Destroy), and event handling. SDK 3.7.1 - 3.10.2 coverage. Triggers on: UdonSharp, Udon, VRC SDK, UdonBehaviour, UdonSynced, NetworkCallable, VRCPlayerApi, SendCustomEvent, PlayerData, PhysBones, synced variables, VRChat world scripting, C# to Udon.

Agent Skills for VRChat UdonSharp

Skills, rules, and validation hooks that teach AI coding agents to generate correct UdonSharp code

About • Install • Structure • Skills • Rules • Hooks • Contributing • Disclaimer

About

VRChat world development with UdonSharp (C# → Udon Assembly) has strict compile constraints that differ significantly from standard C#. Features like List<T>, async/await, try/catch, LINQ, and lambdas cause compile errors.

This repository provides AI coding agents with the knowledge to generate correct UdonSharp code from the start.

Problem	Solution
AI generates `List<T>`, `async/await`, etc.	Rules + hooks auto-detect and warn
Sync variable bloat	Decision tree + data budget
Incorrect networking patterns	Pattern library + anti-patterns
SDK version feature differences	Version table with feature mapping
Late Joiner state inconsistency	Sync pattern selection framework

This is NOT:

A VRChat SDK or UdonSharp distribution
A Unity project (no executable code)
A replacement for official VRChat documentation
A guarantee of all AI behaviors

Issues: Bug reports and knowledge requests are welcome via GitHub Issues. PRs: Pull Requests are not accepted. See CONTRIBUTING.md for details.

Install

Migrating from fork/clone? — Since v1.0.0, this project is distributed as an npm package. You no longer need to fork or clone the repository. Simply run one of the install commands below inside your VRChat Unity project. If you previously cloned this repo, you can safely delete the cloned directory and switch to the npm-based install.
