This filters out over 200 invalid states which were previously considered just fine, including zero-width cakes, buttons with broken facing values, furnace/chest with crazy values, and more.
This breaks down the handling of tile creation even further.
- Introduced a static Tile::override() method to allow overriding the construction class for a specific type of chest. This applies to classes as opposed to save IDs, so you can override Chest::class with MyCustomChest::class and it will take effect for any Chest save ID.
- Removed MCPE stringy save ID constants from public Tile interface. These are now only used for creating saved tiles from a stored chunk, and saving them.
- Renamed Tile::registerTile() to register()
- Tile::create() and Tile::createFromItem() now accept a class parameter instead of a stringy save ID.
- Tile::create() and Tile::createFromItem() were changed to throw \InvalidArgumentException on unknown/unregistered tile types. They also now never return null, but always (except in exception cases) return an object which is an instanceof the base class specified.
this parameter was previously used to send blocks with a different set of flags, immediately, to players. However, the flags have been demonstrated useless and the direct sending is pointless now since packets are buffered now per session, so we might as well take advantage of the batched block update sending.
This is a major change to the way block metadata is handled within the PM core. This separates variant metadata (which really ought to be part of the ID) from state metadata, and in a couple of cases flattens separate states of blocks together.
The result of this is that invalid variants can be much more easily detected, and additionally state handling is much cleaner since meta is only needed at the serialize layer instead of throughout the code.
This now computes BBs relative to 0,0,0 and then offsets them as appropriate. This requires less boilerplate code and also furthers the goal of separating block types from instances.
This now removes the need for recursing around for structures comprised of multiple blocks. Instead, override getAffectedBlocks() to return all blocks that need to be deleted when the current block is deleted, and make sure that only one half of the block drops something. When a player breaks one of the blocks, all the blocks affected by that block will also be destroyed, creating particles and sounds where appropriate.
This fixes creative drops for double plants and beds.
getDrops() should now be overridden only for special cases. There are some non-trivial overrides left that are going to need some extra work to clean up.
