Summary

This PR introduces a new play_theme block that allows users to play background music themes with customizable speed, volume, and playback modes. Theme audio files are now separated from sound effects in the configuration.

Key Changes

  • New Block Definition: Added play_theme block in blocks/sound.js with support for:

    • Theme selection via dropdown (populated from themeNames)
    • Variable assignment for theme instance tracking
    • Speed and volume controls with configurable ranges
    • Loop/Once mode selection
    • Async/Await execution mode
    • Mesh selection via dynamic dropdown extension
  • Code Generation: Implemented JavaScript code generator for play_theme block that:

    • Generates appropriate playSound() calls with theme-specific parameters
    • Supports async/await syntax based on user selection
    • Passes theme name, loop mode, volume, and playback rate to the runtime
  • Configuration Refactoring: Separated audio assets in config.js:

    • Created new themeNames export containing 6 theme tracks (bright, calm, electronic, game, medieval, metal)
    • Kept audioNames for sound effects
  • Toolbox Integration: Added play_theme block to the Sound category toolbox with default shadow blocks for speed and volume inputs

  • Localization: Added translations for the new block and tooltip across 9 languages (English, German, Spanish, French, Italian, Polish, Portuguese, Swedish)

  • Example Update: Updated my_place.flock example to use the new play_theme block instead of generic play_sound for background music

Implementation Details

  • The block follows the same pattern as the existing play_sound block with similar parameter structure
  • Theme names are mapped to dropdown options dynamically from the configuration
  • The generated code maintains consistency with existing sound playback patterns

Summary by CodeRabbit

  • New Features

    • Added a "Play Theme" block to play musical themes with configurable speed, volume, looping, and async options.
    • Improved audio selection: theme files separated from sound effects and audio filenames now show human-friendly labels.
  • Documentation

    • Added translations for the new Play Theme block in all supported languages.
    • Updated example project to demonstrate theme playback.

- Add themeNames export to config.js with the 6 theme-*.mp3 files
- Remove theme files from audioNames (play_sound now shows only SFX)
- Add play_theme block definition to blocks/sound.js
- Add play_theme code generator to generators/generators.js
- Add play_theme as first item in the Sound toolbox category
- Add translations for play_theme in all 8 locale files (es marked as ai)
- Update my_place.flock demo to use play_theme block

Poem

🐰 I hopped a new block into the glade,

A theme to play beneath the shade.
Tunes named bright, calm, game, and more,
I patched the names and opened the door.
🎶 Hop, click, play — behold the score!

17-88: LGTM!

The play_theme block definition correctly mirrors the play_sound block pattern with appropriate adaptations:

  • Uses THEME_NAME field populated from themeNames
  • Shares variableNamePrefix = "sound" for consistent variable numbering across sound blocks
  • Correctly attaches the dynamic_mesh_dropdown extension and block event handler

Consider improving dropdown readability by transforming theme filenames into user-friendly labels:

💡 Optional: Improve dropdown display names
 {
   type: "field_dropdown",
   name: "THEME_NAME",
   options: function () {
-    return themeNames.map((name) => [name, name]);
+    return themeNames.map((name) => {
+      // Transform "theme-bright.mp3" to "Bright"
+      const displayName = name
+        .replace(/^theme-/, "")
+        .replace(/\.mp3$/, "")
+        .replace(/^\w/, (c) => c.toUpperCase());
+      return [displayName, name];
+    });
   },
 },

- Add audioFileToLabel() to config.js: derives display names from SFX
  filenames (e.g. phaserDown1.mp3 → Phaser Down 1, laser1.mp3 → Laser 1)
- Add getThemeDisplayName() to config.js: looks up theme_*_option translation
  key with fallback capitalisation (e.g. theme-bright.mp3 → Bright)
- Update play_theme and play_sound blocks to use these helpers
- Add theme_bright/calm/electronic/game/medieval/metal_option to en.js
- Add same keys to es.js marked as // ai
