Maintain legacy UniRx codebases by applying Observable sequences, ReactiveProperty patterns, and MainThreadDispatcher integration. This Skill provides actionable patterns for Unity 2019–2021 LTS projects, covering UI event handling, coroutine synchronization, and best practices for evolving reactive code without immediate migration pressure.

Observable sequences and ReactiveProperty enable reactive data binding in Unity. Use ReactiveProperty for state management, compose Observables for event chains, and coordinate with MainThreadDispatcher to ensure UI updates execute safely on the main thread in large codebases.

MessageBroker in UniRx enables publish-subscribe patterns for decoupled event communication across your game logic. Combined with Observable sequences, it supports scalable event distribution while maintaining thread safety through proper MainThreadDispatcher coordination.

Plan R3 adoption by first documenting UniRx usage patterns—Observable transformations, ReactiveCommand, and dispatcher patterns. This Skill covers migration considerations and provides guidance to transition legacy reactive codebases toward modern approaches while maintaining stability.

UniRx integrates directly with MVVM by using ReactiveProperty for view model state, ReactiveCommand for user interactions, and MessageBroker for cross-ViewModel communication. This Skill provides MVVM-specific guidance and code samples for maintaining large reactive Unity projects.

UniRx requires explicit MainThreadDispatcher usage to safely update UI from background Observables. Large event chains can become difficult to debug; this Skill covers synchronization patterns, best practices to prevent common pitfalls, and when to simplify complex Observable compositions.
