Decrease memory usage 7x!
New features:
- Memory footprint is 7x smaller. Can reach 100 render distance on 32-bit compilation!
- Chunk generation is much faster (don't need to allocate so much space).
- Fix movement bug that was causing snapping-to-edges for the past month.
- No longer crashes when minimizing / alt-tabbing.
- Prioritize meshing existing chunks over new ones.
- Adding/destroying blocks will look good even while other chunks are queued up to be meshed.
- Prettier and scarier underwater tint.
- No more background pixels shining through terrain (unless looking through water.)
- Smoother mouse.
- Disable raw mouse input by default. (Can toggle with R.)
Technical details:
- Represent world using interval maps instead of arrays.
- Chunk meshing tiny bit slower because accessing arrays is O(1) but accessing interval maps is O(log(num intervals)).
- Starting window dimensions can now be anything, instead of only 800/600.
- Wake up threads with the proper amount of
cv.notify_one()instead of shotgunning withcv.notify_all(). - T-junctions are now fixed by filling in all pixels with max depth (1.0) except for ones where we drew a transparent pixel (e.g. leaves).
- Clean up old code by making variables/functions const and passing classes by reference.
Controls:
- F11 fullscreen
- R toggle mouse raw input
- T toggle t-junction fixing
- Mouse look around
- WASD move around
- Shift/space move up/down
- ESC quit
- N toggle noclip
- P cycle polygon mode
- [+ or numpad+] (press once or hold) increase render distance
- [- or numpad-] (press once or hold) decrease render distance (without unloading existing chunks)
- C toggle face culling
- Left-click destroy block
- Right-click place flowing water
- F3 enable debug overlay
- Scroll change block type (active block type visible in debug menu)
