UdonSharp Ports

TL;DR: Five VRChat UdonSharp community packages ported to CVR WASM, each with source + notes on what survived the translation and what had to change. If you’re coming from UdonSharp, start with UdonSharp ↔ CVR WASM Mapping for the API-level reference, then read these for how the patterns look in practice.

Snippets

If you’re looking for quick pattern conversions rather than whole packages, see UdonSharp snippet ports — six short VRChat docs snippets (spinning cube, teleport, get players, cross-behaviour comms, …) side-by-side with their CVR WASM versions.

The packages

Package	Core mechanic	Ports cleanly?
AAChair	Chair that auto-fits the avatar	Partial — station removed, bone math replaced with height
OpenFlight	Winged flight with flap detection	Core only — flap flight depends on hand tracking
HnFClimbing	Grip-to-climb walls	Partial — hand transform approximated with viewpoint
PlayerPicker	Pick up and move other players	Rewired — CVR routes this via explicit messages
UdonChat	In-world chat with keyboard	Controller only — keyboard UI left as an exercise

What doesn’t translate, regardless of package

These Udon concepts have no direct CVR WASM equivalent, so any package that leans on them needs surgery:

• VRChat stations — no CVR WASM station API. Use CCK’s seat components wired by UnityEvent.
• Hand transforms / tracking data — VRCPlayerApi.GetTrackingData(LeftHand|RightHand) is not exposed. Fall back to the head viewpoint from Player.GetViewPoint(), or drive motion from CVRInput axes.
• Bone positions — VRCPlayerApi.GetBonePosition(HumanBodyBones.X) is not exposed. Use scalar Player.GetCurrentHeight() or skip the feature.
• UdonSynced fields — all sync in WASM is explicit. Replace with Networking.SendMessage + OnReceiveMessage.
• OnDeserialization / RequestSerialization — not a thing in WASM. Re-broadcast on state change.
• VRChat whitelists / download helpers — CVR uses world permissions (WebRequest, UdpConnection) with a different permission surface.

Running the ports

All port sources are served under /assets/examples/ports/<package>/. Drop the relevant .cs files into your CVR WASM Unity project’s Assets/ folder and wire the GameObject fields the page describes.
