Add on_finished_sound for Bedrock Resource Pack Sounds and UI

Hello Minecraft Team,

I would like to suggest adding a new event called on_finished_sound for Minecraft Bedrock Resource Packs.

Currently, creators can play sounds, but there is no native way to detect when a sound has finished playing. This makes it difficult to synchronize animations, dialogues, UI, and other interactive elements without relying on timers or scripts.

An on_finished_sound event would allow creators to trigger actions automatically when a sound ends, making resource packs more reliable and flexible.

This would greatly improve:

• Dialogue systems

• Cutscenes and cinematics

• UI transitions and interactions

• Audio-driven animations

• Tutorials and story experiences

For example:

{
  "sound": "custom.narration",
  "on_finished_sound": "show_next_dialogue"
}

This feature would be especially useful for custom UI created with Bedrock Resource Packs, allowing interface elements such as buttons, menus, progress bars, or dialogue windows to appear, disappear, or update exactly when a sound finishes.

Adding this event would provide creators with precise audio synchronization while keeping resource packs simple and reducing the need for workarounds or scripting.

Thank you for considering this suggestion!
