Reason: in a future port to GDExtension, that class won't be available.
This may also apply to Map and HashMap.
Note: the issues in streams were not hit so far because they are in
multi-block load/save functions. We've been loading and saving blocks
one by one at the moment.
- Made a bunch of changes to comply with Godot 4 API
- Use Godot's Vector3i and add the missing stuff with helper functions
- Transvoxel uses custom attributes API, the old way would not work
- Wrap MeshOptimizer in a unique namespace (see build script why)
- Added clang-format file for the module as some rules now differ
- Prevent thirdparty code and lookup tables from being clang-formatted
- Very likely full of runtime bugs that need fixing
With this mode enabled, editing anywhere becomes possible.
All edited blocks are loaded at once when the stream is assigned.
The generator is used on the fly to fill the gaps, instead of being
pre-emptively cached only nearby the viewer to allow editing.
Editing is still on the main thread, so this can cause stalls if
the generator is complex. There is also no controlled limit on how
much data gets loaded, so if edited data is larger than RAM, it will
not be playable. The feature is already quite usable, but more work
may be done for wider viability.
- VoxelGenerator no longer inherit VoxelStream
- VoxelStream is now more focused on files
- Nodes have separate stream and generator properties
- Generators use 2 dedicated threads instead of sharing a single one with streams
- TODO Image.lock() is problematic for multithreading
- TODO Voxel graph can cause RWLock contention if edited while it runs
- TODO Saving generator output no longer works, need to put it back
- Added a global file locker so threads can synchronize when accessing files
- Added mutexes to serialize access to file streams (i.e to call in series)
- VoxelStream API now expects implementations to be thread-safe
- Did some logic/data separation in RegionFile in case we need an
in-memory implementation, however I might just use SQLite in the
future instead
