This happened when a block was set into the world with a direct update, when an entry for that block was already present in the changedBlocks map. This fixes the bug by removing the entry from the changedBlocks map to avoid sending outdated block updates in batches.
Chunks were used by tiles for a couple of things:
- 1. for coordinates - which can be gotten using bitshifts
- 2. setChanged() - which is unnecessary as seen in the previous commit
Removing this circular dependency was actually remarkably easy to do.
This allows the removal of lots of ugly code, and also exposes lots of similarities with how this update type was handled. This can be further improved in the future to more generically handle cases.
I realized in the process of changing this, that it might actually be simpler to treat to treat scheduled updates and neighbour updates as one and the same. They use the same mechanism for being saved on chunks (TileTicks),
and doing that would make updating only require one queue instead of two.

this is not technically correct behaviour, but this preserves the current behaviour.
save() calls saveChunks() which saves any chunks found to be modified. But chunk unloading does this anyway, so it's better to unload first and then trigger the save mechanism, to avoid saving chunks twice.
it appears that errors are occurring in the exception handler when handling corrupted regions, leaving regions in the provider index with incomplete location tables. This causes strange-looking errors later down the line.
This moves the region assignment to the end of the condition to avoid leaving incomplete/corrupted regions in the location table when errors occur.
This now removes logging from the level providers (for the most part) and replaces it with exception throws and catches. The implementation using the providers should catch these exceptions if they are thrown.
This code is no longer necessary, because entities are constructed with a Level instead of a Chunk since API 3.0.0-ALPHA4. This means that they will not get allocated in the wrong chunk at runtime after having been saved on the wrong chunk by something else (such as an older version of PM). They will instead be allocated in a chunk selected by bitshifting their coordinates.
This is necessary to be able to fix#1789 without causing entities affected by the infamous bitshift-on-floats bugs to inexplicably vanish.
So this came from a bugfix (795d6c8ddf1148dfe6de8ff5ef38a96aee6124fe) which fixed a memory leak related to entities getting kill()ed on chunk unload.
HOWEVER, me2016 did NOT realize that this code is actually entirely pointless and causes unexpected behaviour.
removeEntity() is used in 2 places in the core code:
1. in Entity->close() (so close() doesn't need to be called again, obviously)
2. in Entity->switchLevel() (which then causes the entirely unexpected behaviour of close()ing the entity on level change.
Conclusion: This code is pointless. This fixes the bugfix.
MOP doesn't make any sense anyway.
RayTraceResult is a container which represents the point at which a line hits a bounding box. No dependence on blocks or entities is wanted or needed.
MovingObjectPosition has API changes to allow it to wrap RayTraceResult, but nothing uses MOP anymore anyway.
This would allow modularisation of the pocketmine\\math namespace.
Fixes#1903Closes#1906, which, while a pretty solution, is very inefficient (see PR discussion). This is an optimization of microscopic proportions, but the point still stands.
This is a rather larger commit than I'm happy with, but oh well.
This kills off the enormously overcomplicated BlockIterator and replaces it with a VoxelRayTrace class containing ray tracing generator functions. These functions are independent of any Level. They yield Vector3 objects with current ray trace positions to allow implementations to handle the intercepted blocks in their own ways.
Living->getLineOfSight() now uses VoxelRayTrace instead of BlockIterator.
