What is the vrc-udon skill?

It is a specialized capability for Claude Code that provides patterns and best practices for scripting VRChat worlds using UdonSharp.

Can it help optimize world performance?

Yes, it includes anti-patterns and checklists to help minimize synced variables and prevent performance-draining polling in Update loops.

What languages and frameworks does it support?

It is designed specifically for UdonSharp, which allows developers to write C# scripts that compile into VRChat Udon assembly code.

Does it support late joiners?

Yes, it includes specific patterns for OnPlayerJoined events to ensure players who join an instance later receive the correct current state of the world.

How does it handle networking and synchronization?

It implements strict ownership models and RequestSerialization patterns to ensure data is synced correctly between the object owner and all other players in the instance.

Game Development

Streamlines VRChat world scripting by implementing optimized UdonSharp patterns for networking, synchronization, and player interactions.

About

This skill provides a comprehensive framework for developing VRChat worlds using UdonSharp, focusing on the complexities of the VRChat SDK's networking model. It helps developers manage object ownership, ensure state consistency for late-joining players, and optimize network bandwidth through efficient serialization. By enforcing best practices for event-driven communication and local versus global state management, it reduces common bugs related to synchronization and performance in social VR environments.

Key Features

Automated ownership transfer and synchronization patterns
Event-driven communication using SendCustomEvent and NetworkEvents
0 GitHub stars
Late-joiner state recovery and serialization handling
Network bandwidth optimization and variable syncing logic
Boilerplate generation for common UdonSharp behaviors

Use Cases

Optimizing network performance for high-capacity VRChat instances
Building interactive world elements like doors, buttons, or multi-user games
Synchronizing complex world states across multiple players in real-time
