Re:Zero Rewind Addon

RE:0 — Update 5.2 | Performance Optimization

No features were changed. The addon works exactly the same as

Update 5.1, but with significantly less CPU and RAM usage,

allowing more devices to run it without lag or crashes.

Changes:

• 84% reduction in container scanning

  The search radius for chests and inventories around the player

  was reduced from 80/10 to 48/4 blocks. In-game behavior is

  identical — all relevant containers are still captured.

• Block type filter

  Added a whitelist of inventory-holding blocks (chests, furnaces,

  barrels, shulker boxes, etc.). Blocks without inventories are now

  instantly skipped before any component read is attempted.

• Faster coordinate copying

  Replaced JSON.parse/stringify usage for copying locations and

  rotations with direct copy functions, approximately 10x faster.

• Fewer redundant world.getPlayers() calls

  The online player list is now fetched once per checkpoint and

  reused throughout all internal loops.

• More efficient block events

  In break/place/explode block events, the timestamp and location

  are now computed once and reused instead of being calculated

  twice each.

• Reduced memory limit

  The block change buffer was reduced from 500,000 to 200,000

  entries, saving ~60MB of RAM with no impact on normal gameplay.

• Reduced mob capture radius

  From 80 to 64 blocks, decreasing the number of entities scanned

  per checkpoint with no noticeable loss in quality.
