this significantly reduces the size of schemas when state remaps are used (see pmmp/BedrockBlockUpgradeSchema@85b83b360e).
in addition, this will likely offer a substantial performance and memory saving when walls get flattened, which will eventually happen.
since PHP emits empty JSON objects as arrays, this makes it pretty annoying to work with the schemas in other languages. However, nullability is something most languages understand pretty easily.
This should continue to support old schemas.
due to technical limitations, this requires separating them back into two different block types. However, this isn't too egregious since it's just one flag, and actually simplifies some code.
closes#5478
the following things are currently not implemented:
- particle/sound effects when an entity extinguishes itself
- particle/sound effects when mixing different stuff in a cauldron
- powder snow cauldron
both of these things are contingent on #5169, but for the time being, the PR is functionally complete and I want to move on to something else without being stalled by the particle+sound problem (which I haven't yet decided how to solve).
Bedrock block entity updates don't directly trigger block rendering
updates. This is a problem when the block entity data affects the
block's appearance directly (e.g. cauldron water colour, flower pot
contents), because it means changing them won't directly result in a
client-side render update.
This hack allows tiles to spoof block updates without actually changing
the server-side block, keeping the internals and API clean of random
shitbox workarounds.
fixes#5174fixes#4944
the old impl prevented registering more than one meta -> state mapping since the legacy numeric ID map would throw an exception if attempting to map the same ID more than once.
these have working inventories, and their crafting menus will 'just work' once the items for the associated recipes have been implemented (maps, netherite).
