Summary

This pull request adds support for controlling and querying emote playback in the Unity wearable preview, including play, pause, seek, stop, and sound controls, as well as communication between Unity and JavaScript for these features. The changes introduce new methods in the emote animation controller, expose them through the JS bridge, and ensure proper state handling and cleanup.

Emote Playback Controls:

• Added methods to EmoteAnimationController for pausing, resuming, seeking (GoToEmote), enabling/disabling sound, and querying emote state (length, playing, paused, has sound). These allow for fine-grained control of emote playback. [1] [2] [3] [4]

• Updated PreviewController to expose these controls and state queries, delegating to EmoteAnimationController.

JS Bridge Integration:

• Exposed the new emote control and query methods to JavaScript via JSBridge, enabling JS to control emote playback and receive state updates from Unity.

• Implemented corresponding native calls and message handlers in JSBridge.jslib for communication between Unity and the browser, including posting emote state updates. [1] [2] [3]

Emote State Management and Cleanup:

• Improved emote cleanup by adding a ClearEmote method to both AvatarLoader and PreviewController, ensuring proper disposal and state reset when cleaning up emotes. [1] [2]

Other Adjustments:

• Prevented loading the "idle" emote as an embedded emote, ensuring it is treated as a null emote to avoid fallback to T-pose.

• Removed a debug log statement from the emote loading process for cleaner logs.
