What problem does it solve? Adding audio and video to a Decentraland scene involves choosing between AudioSource, AudioStream, and VideoPlayer, wiring video textures onto meshes, handling retriggering pitfalls with LWW-CRDT dedup, and sourcing legal audio files — this Skill guides that entire workflow with verified API patterns. ## Core Features & Use Cases - Component Selection Guidance: Decision flow for choosing AudioSource (local spatial sound effects), AudioStream (radio/live URL streams), or VideoPlayer (video on planes or GLTF nodes). - Free Audio Catalog: A reference catalog of 50 downloadable Decentraland audio clips with curl-ready URLs covering music, ambience, interactions, sound effects, and game mechanics. - Reliable Playback Patterns: Verified helpers like AudioSource.playSound for retriggering, audioEventsSystem/videoEventsSystem for state callbacks, and finish-detection via the playing flag flip. - Use Case: A creator building a nightclub scene can add looping dance music, a door-open sound on click, and an HLS live video stream on a screen — all with correct spatial settings and event monitoring. ## Quick Start Ask the assistant to add background music and a clickable sound effect to your Decentraland scene using the audio-video skill.
