audio-video

Create an entity with AudioSource (playing: false), then call AudioSource.playSound(entity, clipUrl) inside a pointerEventsSystem.onPointerDown callback. Use playSound rather than mutating getMutable().playing, because repeated identical writes can be deduplicated by the LWW-CRDT and silently ignored.

AudioSource plays local audio files (mp3, ogg, wav) and is spatial by default, making it suited for sound effects. AudioStream plays audio from an external URL like a radio stream, is non-spatial by default, and suits continuous background music or live broadcasts.

Create an entity with MeshRenderer.setPlane, add a VideoPlayer component with the video src, then apply Material.Texture.Video({ videoPlayerEntity }) via Material.setBasicMaterial or setPbrMaterial. For curved screens on GLTF models, use GltfNodeModifiers to swap the material.

No, AudioSource only works with local file paths such as assets/Audio/clip.mp3. Download external audio into the scene's assets/Audio/ folder first with curl, then reference the local path in audioClipUrl.

Hand-mutating getMutable().playing = true can be swallowed by LWW-CRDT deduplication when values are unchanged, so later clicks do nothing. Use AudioSource.playSound(entity, clipUrl), which writes the full component and reliably retriggers from position 0 every call.

The limit depends on each player's quality setting: 1 on Low, 5 on Medium, and 10 on High. Treat 1 as the only safe floor and avoid playing multiple videos at once unless explicitly required.
