WSC World Save Chunks

📜 Changelog — WSC v1.0.3

New Features

• Added new commands:
  • /wsc config opsPerTick <value> — dynamically adjust the per‑tick operation limit in‑game.
  • /wsc debug — displays a summary including snapshot count, current mode, work queue size, and reservation count.
• Enhanced /wsc repair reporting: now shows not only the number of differing chunks but also:
  • how many blocks were actually changed,
  • how many TileEntities were updated,
  • how many TileEntities were cleared.

Optimizations

• Unified section hashing: both snapshot creation and world comparison now use the same algorithm (BlockState.hashCode() per position), eliminating false differences.
• Fast empty‑air skip: sections consisting only of air are quickly validated without full scanning.
• TileEntity comparison simplified: only presence/absence is checked, avoiding false positives from dynamic NBT changes.
• Automatic cleanup on world exit: snapshots and reservations are cleared on ServerStoppedEvent, preventing infinite loading screens when re‑entering a world.

Improvements

• Chunk reservation system: each chunk in the queue is tagged with an owner to prevent conflicts in LAN/multiplayer scenarios.
• Action bar notifications: all messages now appear above the hotbar instead of cluttering the chat.
• Accurate statistics: repair and debug commands provide precise counts instead of rough estimates.

✨ In short:
v1.0.2 introduced repair and basic optimizations.
v1.0.3 perfects the system with unified hashing, zero false positives, new configuration and debug commands, and smoother multiplayer compatibility.

📜 Changelog — WSC v1.0.2

New Features

• Added /wsc repair command to fix all chunks that differ from their saved snapshots without removing them.
• Introduced localization support via JSON language files. Now messages are translated into multiple languages (English, Russian, Belarusian, Ukrainian, German, French, Spanish, Italian, Japanese, Polish, Portuguese).

Optimizations

• Snapshots are now stored per section (16×16×16) with block palettes and hashes, reducing memory usage.
• Hash-based comparison of sections allows fast detection of differences without scanning all blocks.
• Selective restoration: only blocks and TileEntities that differ are updated, instead of replacing entire chunks.
• Work queue with per-tick limit ensures heavy operations are spread across ticks, preventing lag spikes.
• Dimension-aware snapshot keys prevent collisions between worlds.

Improvements

• Added status command (/wsc status) to display current mode and snapshot count.
• Enhanced TileEntity handling: precise NBT restore and safe cleanup of unexpected TE.
• Better handling of chunk load/unload/watch events with deferred snapshot/restore tasks.

✨ In short:
v1.0.0 was a raw prototype that replaced whole chunks.
v1.0.2 is a polished, optimized release with section-based snapshots, selective repair, localization, and smoother performance.

🔄 Features in v1.0

1. Chunk Snapshot Recording

   • Use /wsc on to start recording.
   • Chunks are automatically saved when they load.

2. Automatic Restoration

   • Chunks are restored when they unload or when a player re-enters them.
   • Block states and TileEntities (e.g. chests, furnaces) are fully restored.

3. Manual Control

   • /wsc off restores all recorded chunks and disables recording.
   • /wsc off nsc disables recording but keeps all changes.

4. Multi-Dimension Support

   • Works across Overworld, Nether, and End.
   • Snapshots are dimension-aware to prevent cross-world conflicts.

5. Performance Optimizations

   • Only changed chunks are restored.
   • No forced chunk loading — works with already loaded chunks.

6. Safe TileEntity Handling

   • Restores NBT data and reinitializes block entities correctly.
   • Prevents visual glitches and inventory loss.
