April 2026 monthly summary for developer work across two repos (decentraland/protocol and decentraland/unity-explorer). Focused on delivering real-time communications, robust data messaging, and enhanced LiveKit-based media experiences that drive collaboration and user engagement in scenes, while improving stability and maintainability through testing and refactors. Key features delivered: - decentraland/protocol: Implemented topic-based messaging in the Comms API with SubscribeToTopic, PublishData, ConsumeMessages RPCs and an UnsubscribeFromTopic method, enabling JSON payload exchange across scenes. Designed per-RPC response handling to avoid conflicts and documented wire-format semantics for cross-scene data flow. - decentraland/unity-explorer: Advanced LiveKit media streaming and data messaging. Enhancements include enriched participant metadata in GetActiveVideoStreams, automated audio track resolution, support for playing all audio tracks in a LiveKit room, improved active-speaker switching, and new data messaging capabilities exposed to scenes via CommsApiWrap (PublishData, SubscribeToTopic, ConsumeMessages) with rate limiting and a 16KB payload cap. Added JS bindings and documentation for scene integration. - Cross-repo alignment and quality: Expanded unit tests for CommsApiWrap, added data messaging tests, and updated documentation around LiveKit features and data channels. Major bugs fixed: - Stability and resilience of LiveKit playback: auto-recovery when a track dies, throttled empty-audio rescans, and prevention of audio disruption during video recovery; improved handling for late-joining participants and display-name resolution paths for cast/casting workflows. - Data path and integration fixes: robust, thread-safe buffering for network DataReceived events; cleanup paths on dispose; and wire-format alignment to support reliable topic-based messaging across scenes. Overall impact and accomplishments: - Significantly improved real-time collaboration capabilities with reliable, topic-based messaging and richer media experiences in scenes, reducing developer friction for scene authors and enabling more dynamic interactions. - Increased system resilience under dynamic participant changes (joins/leaves) and network conditions, while maintaining clean separation of concerns between CommsApi, LiveKit integration, and scene data channels. - Strengthened engineering practices with added tests and documentation, facilitating future feature work and maintainability. Technologies and skills demonstrated: - Protobuf RPC design and cross-scene data exchange (SubscribeToTopic, PublishData, ConsumeMessages, UnsubscribeFromTopic). - LiveKit integration in Unity, including metadata handling, multi-track audio playback, active speaker logic, and data channels. - Data channel design with per-topic rate limiting, payload caps, and thread-safe buffering. - API design for scene integrations, JS bindings, and robust testing and documentation.
