irongingot v1.6.4

Changelog - 2026-06-28

Item Physics

• Client-side prediction - items send initial velocity at spawn so the
  client interpolates movement smoothly. No more jittery teleport corrections
  during flight.

• No air drag - 0.98× multiplier removed (vanilla behavior: gravity only).
  Horizontal velocity holds until ground contact.

• Ground sync - items send final position + zero-velocity packet on
  touchdown so the client doesn't bounce with stale velocity.

• Distance culling - item spawn, teleport, despawn, and pickup broadcasts
  filtered to view_distance × 16 blocks (min 64), preventing send-queue
  floods.

Crafting

• Stair recipes - stone, stone_brick, brick, nether_brick, and sandstone
  stairs now craftable (6 blocks → 4 stairs), declared in the recipe book.

• Recipe book grid fix - auto-placing a recipe in the crafting table now
  returns existing grid items to inventory before clearing.

• Right-click output - right-click on a crafting output slot now picks up
  1 item instead of the full stack.

Combat

• Zombie reach - attack range reduced from 3.0 to 2.0 blocks.

• Armor damage - equipped armor loses 1 durability per hit (non-fall,
  non-drown, non-starve, non-cactus damage). Broken pieces are unequipped.

Block Interaction

• On-demand state registration - generated doors, chests, stairs,
  fences, and other interactive blocks now lazily register special-block
  state on first player interaction instead of at chunk-load time.

• Special block serialization - world.json saves only block-change-backed
  states; transient generated states excluded to reduce size and avoid stale
  data.

• Barrel placement - no longer overwrites existing special-block entries.

• Item throw - Q-drops use speed 0.5 / vertical offset 0.2 for flatter
  trajectories.

Performance

• 20 TPS default - tick_interval changed from 100000 to 50000 in
  server.conf.

• Disk sync interval - DISK_SYNC_BLOCKS_ON_INTERVAL enabled by default.
  Block changes save only on the periodic ~15s interval instead of every
  change, avoiding tick-loop stalls on large worlds.

• Terminal UI removed - plain timestamped stdout logging replaces the
  escape-code terminal panel.
