Dec 1, 2025December 2025 monthly summary for decentraland/unity-explorer focused on shipping the Social Emotes System and stabilizing cross-client social interactions. Delivered a feature-rich avatar emotes experience with an Emotes Wheel accessible via 3D context menu, synchronized animations across clients, and contextual UX (target user name, updated tooltips). Implemented robust audio mapping for emotes (including nullable/result handling) and refined loading/playing logic to improve responsiveness. Reduced log noise in the emote subsystem to streamline debugging and performance. Added comprehensive data flow support (DTOs) and protocol adjustments to enable directed and non-directed emotes, ensuring state coherence across clients. A critical fix prevents avatars from rotating when sitting by validating initiator data, improving visual stability in social interactions. Addressed high-severity issues in audio mapping for multiple outcomes and further reduced runtime logging. Commit activity centered on enabling social interactions, improving reliability, and optimizing performance, with notable changes in emote replication, outcome handling, and UI/UX improvements.
