API Bridge 1.2.3 для Minecraft 1.21.11 (Fabric)

v1.2.3 — RLE Depth-Map + Sparse Inventory

Enhancements

• viewport_blocks now uses RLE compression — Previously 288 ints (144 flat [depth, blockId] pairs). Now consecutive identical rays are merged into runs: [[count, depth, blockId], ...]. Typical scene: ~40-60% fewer tokens vs. flat format. Empty state returns [].
• inventory.slots now sparse — Previously 41 fixed [item_id, count] entries (82 ints + JSON overhead). Now only non-empty slots are included, each as [slot_index, item_id, count]. Empty state returns []. Early-game saving: ~6-15 token vs 165.

v1.2.2 — Depth-Map with Surface Block IDs

Enhancements

• viewport_blocks now returns [depth, blockId] pairs — Previously a flat depth-only array (144 ints). Now each of the 144 rays produces two values: depth (1–32 = distance to nearest solid) and the numeric block ID of that surface block (0 if clear). Total 288 ints.
• AI can now distinguish stone vs. dirt vs. water at each ray without a separate API call.

Bug Fixes

• Fixed stride in viewport_blocks doc — Index formula corrected from depth * 288 to depth * 144 (each depth layer has 16×9 = 144 cells, not 288).
• viewport_entities no longer pads empty slots — Removed 16-slot fixed-size padding. Returns only actual visible entities (0–16 elements).

v1.2.1 — Registry Endpoints + Bug Fixes

New Features

• Registry Dump Endpoints — Two new runtime endpoints for resolving numeric IDs:

  • GET /api/registry/entities — Dumps id → "minecraft:name" from BuiltInRegistries.ENTITY_TYPE
  • GET /api/registry/items — Dumps id → "minecraft:name" from BuiltInRegistries.ITEM
  • AI agents can call these once per session for accurate ID lookup, eliminating hardcoded tables.

Bug Fixes

• world.time clamping — Observation now returns dayTime % 24000 (range 0–24000) as documented, instead of raw tick value. Fixes ObservationProvider.java:143.
• viewport_entities FOV filtering — Entities are now filtered by the player's actual field of view (frustum cone). Previously all entities within 48 blocks were included regardless of direction. Fixes ObservationProvider.java:363-371.
• Entity ID table in docs — Both OBSERVATION_SCHEMA.md and AI_AGENT_GUIDE.md entity type ID tables updated to match the real Minecraft 1.21.11 registry order (from BuiltInRegistries.ENTITY_TYPE).
• API.md doc updates — Added documentation for registry endpoints; updated viewport_entities description to clarify frustum filtering.
