MC 1.21.9 changed how some items and blocks are registered — 24 block
items (copper bars/chains/lanterns variants, potted azalea renames) and
additional blocks are now registered outside of Items.java/Blocks.java
field declarations, making the previous source-field-order-based palette
generation produce incorrect protocol IDs.
Regenerated ItemPalette1219.cs using server registries.json (1488 items,
up from 1464) and Palette1219.cs using blocks.json (1166 blocks with
correct state IDs). Added 37 new enum values to ItemType.cs (35 new +
DryShortGrass/DryTallGrass for backward compat) and 9 new values to
Material.cs.
Verified all item/block/entity identification against a 1.21.10 server.
Made-with: Cursor
- Palette1219.cs: 1053 blocks with new copper chests, copper golem
statues, copper torches, shelves, oxidized lightning rods, iron chain
- EntityPalette1219.cs: 153 entities (+copper_golem at 27, mannequin at 82)
- ItemPalette1219.cs: 1464 items (generated via gen_item_palette.py)
- EntityMetadataPalette1219.cs: 37 serializers (COMPOUND_TAG removed,
+CopperGolemState, WeatheringCopperState, ResolvableProfile)
- PacketPalette1219.cs: updated clientbound IDs for 4 new debug packets
and GameTestHighlightPos, plus config CodeOfConduct/AcceptCodeOfConduct
Also update gen_entity_metadata_palette.py FIELD_TO_ENUM with the three
new serializer type mappings.
Made-with: Cursor
- ItemPalette1216: 1415 items (generated from decompiled Items.java)
- EntityPalette1216: 151 entities (HappyGhast at index 56, all after +1)
- Palette1216: block states (DriedGhast 32 states at 13826-13857, all after +32)
- PacketPalette1216: clientbound +3 (Waypoint, ClearDialog, ShowDialog),
serverbound +2 (ChangeGameMode at 0x04 shifting all after, CustomClickAction at end),
config clientbound +2 (ClearDialog, ShowDialog),
config serverbound +1 (CustomClickAction)
- Version routing in Protocol18.cs, PacketType18Handler.cs, EntityMetadataPalette.cs
updated to select 1216 palettes for protocol >= 771
- EntityMetadataPalette reuses 1215 (EntityDataSerializers unchanged)
Made-with: Cursor
Add complete protocol 769 support for Minecraft 1.21.4:
- Version constants: Add 769 to supported versions, MC_1_21_4_Version constant,
and version string mappings (including 1.21.3 -> 768 compatibility)
- Item palette: 10 new items (Resin series + Eyeblossom), generated ItemPalette1214
- Entity palette: Remove CreakingTransient (149 entities, down from 150)
- Block palette: 10 new blocks with correct blockstate ID ranges from server data
- Packet palette: Serverbound packet ID reshuffling - PickItem split into
PickItemFromBlock/PickItemFromEntity, new PlayerLoaded packet inserted after
PlayerInput, subsequent IDs shifted accordingly. Clientbound unchanged.
- PlayerLoaded: Send empty PlayerLoaded packet after JoinGame processing (>= 1.21.4)
- EntityMetadata/DataComponents: Reuse 1.20.6 palettes (unchanged registries)
- Update all version guard checks from MC_1_21_2 to MC_1_21_4
Made-with: Cursor
* First implementation
* Improve chunk reading performance
* Fix indentation
* Remove debug information
* Update MultiBlockChange packet
* Move skip varint to a method
* Fix crash when not using block palette
* Fix DataTypes.cs not compiling on .NET 4.0
Binary (0b) values not handled so converted to Hexadecimal (0x)
* Use the 1.16 chunk parsing code for 1.15 too
Document the differences in padding and factor the code

Fix encoding issues with some languages such as Chinese
by forcing UTF-8 everywhere. Configuration files written
in ANSI/Latin-1 and other encodings will need conversion.
Implement palette generation and investigate palette changes between
versions. Turns out 1.13- has legacy IDs, 1.14 switches to entity
palette and 1.15 refreshes the whole palette just to insert Bee.
Also refactor entity handling code here and there.
Minecraft 1.14 is now fully supported.
- Implement NBT parsing to skip NBT field in chunk data
- Update lighting data format in Chunk Data parsing
- Move Chunk Data parsing into Protocol18Terrain.cs
- Improve PaletteGenerator to greatly reduce palette files sizes
- Re-Generate Palette113.cs to reduce its size (378 Kib -> 50 Kib)
- Generate Palette114.cs (57 Kib instead of 516 Kib with prev format)
- Update Material.cs and MaterialExtensions.cs for new block types
Special thanks to @TheSnoozer and @vkorn for their help!
- Implement global block Palette mechanism
- Add class generation tool from blocks.json
- Regenerate Material.cs and redefine solid blocks
- Migrate previous Material.cs into Palette112
- Generate Palette113 from MC 1.13.2 blocks.json
- Improve Block class to handle up to 65535 block states
- Adjust terrain parsing, small fixes in packets
- Remove unused snapshot-related protocol cases
