this spectactularly stupid bug could also have been addressed using a [^\/] in place of the . in the pattern, but I thought it made sense to make it impossible for this to happen again by making sure the regex only sees the file name.
fixes#5129
this doesn't match the 1.16+ behaviour yet, but it at least recognizes walls that are already in the post-1.16 way and doesn't break them if not interacted with.
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.
