Obtaining data

file name	info	how to get	schema
blockStates.json	Contains the global block palette for a Minecraft version. Contains all of the possible block states. The index of a Block State instance here is the paletted ID, which can be used to idenfify this block state instead of a string.	bedrock-extractor ("BlockStates.json" file)
steve.json	Skin data for clients connecting to BE servers, for default Steve character	bedrock-protocol (capture from proxy)
blockMappings.json	Output of bedrock-extractor
language.json	Translation keys and their English string values.	extract-minecraft-lang (run for new version, then copy the JSON file to minecraft-data)

Updating protocol data

• To update bedrock protocol data, open data/bedrock/latest (or replace "latest" with some older version) and update the proto.yml and types.yml files.
• Go to tools/js, run npm install then npm run build to update the protodef JSON files

To update to a new protocol version:

• Copy data/bedrock/latest files into the old version's folder.
• Open data/bedrock/latest and update the proto.yml and types.yml files and update the !version part at the top
• Go to tools/js, run npm install then npm run build to update the protodef JSON files

then run npm test to test validity
