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.
in almost all cases where ItemTranslator is used, an Item already exists, so it doesn't make any sense to make ItemTranslator go and create another item instance just to pass to ItemSerializer.
this is a sucky solution but it works well enough for this scenario.
From my research it appears that while the client-side MovementInterpolator is active on the client and hasn't yet reached its target, any teleport sent during the lerp will get overridden by the lerp.
This appears to last 3-4 ticks (about 150-200 ms) which explains why this can be reproduced by stopping movement just before the ender pearl lands (human reaction times would make the reproduction unreliable otherwise).
Things to note:
- All entities are affected by this bug.
- MovePlayerPacket appears not to have the problem, but we can't use it because it doesn't work for non-players.
- MoveActorAbsolute and MoveActorDelta are both handled by the same code and will have the same lerping bug.
This is the cleanest solution I could come up with.
