this information will allow us to correct for any bugs introduced by past versions.
however, we still need to propagate this information to permit actually using it when loading data.
to be consistent, these shouldn't be exposed in the API like this...
I'm not very happy with the whole 'type ID map' paradigm (particularly its lack of static analysis guarantees), but the most important thing right now is to get this stuff out of the API so that plugin devs don't try and abuse it. We're not going to change the whole system days before PM5 release.
this doesn't support editing the rear side of a sign, since the 1.12 format doesn't allow us to represent the rear text, and it would necessitate API breaks to support anyway.
However, we can quite trivially support APIs for the sign GUI, which plugins can use to enable editing signs. PocketMine-MP doesn't currently permit this, since it's currently an experimental feature in 1.20, but plugins can simply use Player->openSignEditor() to mimic it.
This is, however, a byproduct of the fact that APIs needed to be added in order to facilitate the use of OpenSignPacket in 1.19.80.
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.

This commit completely revamps the way that blocks are represented in memory at runtime.
Instead of being represented by legacy Mojang block IDs and metadata, which are dated, limited and unchangeable, we now use custom PM block IDs, which are generated from VanillaBlocks.
This means we have full control of how they are assigned, which opens the doors to finally addressing inconsistencies like glazed terracotta, stripped logs handling, etc.
To represent state, BlockDataReader and BlockDataWriter have been introduced, and are used by blocks with state information to pack said information into a binary form that can be stored on a chunk at runtime.
Conceptually it's pretty similar to legacy metadata, but the actual format shares no resemblance whatsoever to legacy metadata, and is fully controlled by PM.
This means that the 'state data' may change in serialization format at any time, so it should **NOT** be stored on disk or in a config.
In the future, this will be improved using more auto-generated code and attributes, instead of hand-baked decodeState() and encodeState(). For now, this opens the gateway to a significant expansion of features.
It's not ideal, but it's a big step forwards.
this commit provides a central place where all block data can go to be upgraded to the latest version (currently 1.19), irrespective of how old it is.
Previously I had issues during debugging, because it wasn't possible to just upgrade a block without deserializing it into a Block object, which isn't currently supported for many blocks.
This commit solves that problem by separating the upgrading from the deserialization.
