Many standard C# features (`List<T>`, `async/await`, `try/catch`, LINQ, generics) **silently fail or refuse to compile** in code that runs in the Udon runtime. Editor-evaluated field initializers are a separate context: they can use some ordinary C# features to generate a final value that Udon can hold. Networking is even more treacherous: modifying a synced variable without ownership produces no error — it just does nothing. Forgetting `RequestSerialization` means your state changes never leave your machine. Standard single-player local testing gives zero signal about these networking bugs because there is only one player.\n\nEvery rule in this skill exists because UdonSharp's default behavior is to **fail silently**. Read the Rules before generating any code.\n\n## Before Writing Network Code\n\nFour architectural decisions that must be made before choosing sync modes or writing any synced variable. Changing them mid-implementation typically requires a full rewrite:\n\n- **Who owns this state?** One owner writes; all others read. If two players can both write (e.g., a shared toggle), you need an ownership transfer protocol — writes without ownership are silently discarded.\n- **When does ownership transfer?** On grab? Interact? Game event? `OnPlayerLeft`? `Networking.SetOwner` is **locally immediate** on the calling client — `Networking.IsOwner(gameObject)` is `true` synchronously after the call, and writing `[UdonSynced]` fields plus `RequestSerialization()` immediately afterwards is safe under an `IsOwner` guard. Concurrent `SetOwner` calls from multiple clients are resolved by network arrival order — there is no client-side arbitration, so accept that the loser's write is overwritten.\n- **What do late joiners see?** State set only by one-time events (`SendCustomNetworkEvent`) is invisible to late joiners. Late-joiner-visible state must live in `[UdonSynced]` variables, which are delivered automatically via `OnDeserialization`; no manual `RequestSerialization()` on join is needed.\n- **What if the owner leaves mid-session?** VRChat automatically transfers ownership to a remaining player (selection rule is not publicly documented), and `OnOwnershipTransferred` fires on all clients. Synced variables are preserved, so state is not frozen; decide upfront whether to keep the current value, reset to a known default, or re-apply/re-broadcast derived state in `OnOwnershipTransferred`.\n\n## Context Preservation\n\nFor complex synced systems, ownership-sensitive refactors, or work resumed after compaction/handoff, consider loading `references/context-preservation.md`.\nIt provides a lightweight task-context note for source of truth, transport, sync mode, storage, ownership, late-joiner behavior, and validation rationale.\nThis is optional guidance for complex work, not a step for small mechanical edits.\nKeep private data and raw transcripts out of any note.\n\nFor VRChat SDK Build Panel validation alerts, red/yellow/white warnings, or\nAuto Fix side effects that involve world scene setup rather than UdonSharp\ncompiler constraints, use `unity-vrc-world-sdk-3` and read\n`references/build-validation.md`.\n\n## Core Principles\n\n1. **Constraints First** — For Udon runtime code, assume standard C# features are blocked until verified. Treat Editor-evaluated field initializers separately and require a final Udon-supported value. Check `udonsharp-constraints.md` before using any API.\n2. **Ownership Before Mutation** — Only the owner of an object can modify its synced variables. Always `SetOwner` → modify → `RequestSerialization`.\n3. **Late Joiner Correctness** — State must be correct for players who join after events have occurred. Design for re-serialization, not just live updates.\n4. **Sync Minimization** — Every synced variable costs bandwidth (see data budget in `udonsharp-sync-selection.md`). Derive what you can locally; sync only the source of truth.\n5. **Event-Driven, Not Polling** — Use `OnDeserialization`, `[FieldChangeCallback]`, and `SendCustomEvent` instead of checking state in `Update()` **for state-change reactions; for hot-path or periodic work, see [Event Dispatch & Cross-Behaviour Call Cost Tiers](references/patterns-performance.md#event-dispatch--cross-behaviour-call-cost-tiers)**.\n\n**Synced arrays: always apply them from `OnDeserialization()`**. Array element\nchanges do not provide a reliable `FieldChangeCallback` signal, and the same\nguidance applies to same-length changes, array reassignments, and length\nchanges. Have the owner call the same idempotent apply method immediately after\nmutation, then request Manual serialization once. If a revision guard protects a\nhistorical one-shot side effect, a late joiner's first `OnDeserialization()`\nreceives the current revision and may otherwise replay that effect. Baseline the\nfirst received revision without the side effect, but run durable `ApplyValues()`\nbefore the baseline check; only later revisions should trigger the one-shot.\nRevision is not ordering or stale-packet protection.\n\n## SDK 3.10.4 event receiver arguments\n\nSDK 3.10.5 is the active and verified target for this Skill.\nSDK 3.10.4: `UdonSharpBehaviour` implements `IUdonEventReceiver` directly.\nAn API that requires a receiver can therefore receive `this` directly:\n\n```csharp\nVRCStringDownloader.LoadUrl(dataUrl, this);\n```\n\nThe receiver argument is still required; only the explicit `(IUdonEventReceiver)` cast is unnecessary on the active SDK. Keep any pre-3.10.4 cast in the historical migration reference only. This follows the [official SDK 3.10.4 release notes](https://creators.vrchat.com/releases/release-3-10-4/) and the SDK source declaration.\n\n### Public fields: Inspector visibility is not persistence policy\n\n`[HideInInspector]` only hides a public field from the Inspector; Unity still serializes it. Use `[HideInInspector] public` when Editor-time DI, baking, or autowiring must persist the value into a Scene/Prefab. Use `[System.NonSerialized] public` for a runtime-only value that another UdonBehaviour must access through direct access or `SetProgramVariable`. When `[HideInInspector]` is intentional, leave a comment explaining why the value must be persisted.\n\n### Editor-evaluated field initializers\n\nField initializers are evaluated as ordinary C# on the Unity/Editor side to produce initial data for the compiled Udon program; their expressions do not run in the Udon runtime. A `Random.Range` call in an initializer is evaluated in the Editor and stored as a baked default, not runtime randomness. LINQ, lambdas, or a same-behaviour static helper that uses `List<T>` can therefore generate an array initializer even though the same code is unavailable from `Start()`, `Interact()`, or another Udon runtime method. The final field type and value must be supported by Udon. Keep generation independent of scene, player, and runtime state, and do not call main-thread-only Unity APIs because field initializers and constructors can run on a loading thread. See `references/constraints.md` for both supported forms and their boundaries.\n\nUse `Start()` or a lazy-init guard only for local or per-client randomness. For shared per-object or per-session seed/state, the owner generates it and stores it in a `[UdonSynced]` field; with Manual sync, establish ownership before writing and then call `RequestSerialization()`. Receivers may apply derived state in `OnDeserialization()` when needed, but that callback is not required for the field synchronization itself, and late joiners receive the current synced state.\n\n## Common Mistakes (NEVER List)\n\nThese Udon runtime and Unity serialization constraints cause either **compile-time failures** or **silent data errors**. Check this list before writing UdonSharp code or serialized initial values.\n\n| # | NEVER do this | Why it fails silently | Use instead |\n|---|---------------|----------------------|-------------|\n| 1 | Use `List<T>`, `Dictionary<T,K>`, or any generic collection in Udon runtime code | Compile error — blocked by Udon compiler | `T[]` arrays, `DataList`, `DataDictionary` (`DataDictionary.EnsureCapacity` / custom capacities require SDK 3.10.4+); Editor-evaluated field generation is the limited exception above |\n| 2 | Use `async`/`await`, `System.Threading`, or coroutines | Udon is single-threaded; these features do not exist | `SendCustomEventDelayedSeconds()` |\n| 3 | Modify `[UdonSynced]` fields without owning the object | Change appears local but is **silently reverted** on next deserialization | `Networking.SetOwner()` before modify, then `RequestSerialization()` |\n| 4 | Forget `RequestSerialization()` after modifying synced fields (Manual sync) | State changes never leave the local client — no error, no warning | Always call `RequestSerialization()` after modifying `[UdonSynced]` fields |\n| 5 | Use `try`/`catch`/`finally`/`throw` | Compile error — exception handling is blocked | Defensive null checks + early return |\n| 6 | Access `Networking.LocalPlayer` in field initializers | Editor-side initial value generation has no player or Udon runtime state | Initialize in `Start()` or use lazy-init guard |\n| 7 | Use `static` fields for per-instance state | Static fields are shared across all instances on the same client and are not synced | Instance fields with `[UdonSynced]` if sync is needed |\n| 8 | Call `RequestSerialization()` every frame in Manual sync | Floods the ~11 KB/s network budget, causing congestion for the entire world | Throttle to 1-10 Hz with change detection; check `Networking.IsClogged` |\n| 9 | Use LINQ (`.Where`, `.Select`, etc.) or lambda expressions in Udon runtime code | Compile error — not supported by Udon compiler | Manual `for` loops with named methods; Editor-evaluated field generation is the limited exception above |\n| 10 | Use `Button.onClick.AddListener()` | Not available in Udon — no runtime delegate support | Configure `SendCustomEvent` via Inspector OnClick |\n| 11 | Mix Continuous and Manual sync concerns on one behaviour | Wastes bandwidth (discrete values in Continuous) or loses control (redundant `RequestSerialization` in Continuous) | Separate behaviours: Continuous for position/rotation, Manual for discrete state |\n| 12 | Write to `[UdonSynced]` fields without an `IsOwner` guard | Non-owner writes are purely local and silently reverted on the next deserialization from the actual owner | `Networking.SetOwner` first if needed (locally immediate), then write under `IsOwner` and call `RequestSerialization()` |\n| 13 | Use `[NetworkCallable]` on an unsupported SDK below 3.8.1 (historical migration only) | Compile error — the attribute and parameterized network-event API are unavailable | Use the active SDK target, 3.10.5; for historical migration notes, use synced variables and react in `OnDeserialization`/`FieldChangeCallback` instead of pairing the","tagline":">-","category":"automation","tags":["agent-skill"],"author":"niaka3dayo","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"niaka3dayo/agent-skills-vrc-udon","creatorName":"niaka3dayo","creatorUrl":"https://github.com/niaka3dayo","sourceUrl":"https://github.com/niaka3dayo/agent-skills-vrc-udon/tree/dev/skills/unity-vrc-udon-sharp","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/niaka3dayo-unity-vrc-udon-sharp#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
