TODO: Flowing water to actually contain flow direction information\r
\r
-TODO: Remove duplicate lighting implementation from Map (leave\r
- VoxelManipulator, which is faster)\r
-\r
FEATURE: Create a system that allows a huge amount of different "map\r

\r
the other chunk making nasty straight walls when the other chunk\r
is generated. Fix it.\r
\r
+Mapgen v4 (not doing):\r
+* only_from_disk might not work anymore - check and fix it.\r
+* Make the generator to run in background and not blocking block\r
+ placement and transfer\r
+* Make chunks to be tiled vertically too\r
+* MAKE IT FASTER\r
+\r
Mapgen v3:\r
* Generate trees better\r
- Add a "trees_added" flag to sector, or something\r
* How 'bout making turbulence controlled so that for a given 2d position\r
it can be completely turned off, and is usually so. This way generation\r
can be sped up a lot.\r
+* Add a way to generate a block partly, so that trees are not added, like\r
+ the chunks in v2\r
+* Add mud "discretely", not by guessing from the noise\r
\r
Mapgen v4:\r
-* only_from_disk might not work anymore - check and fix it.\r
-* Make the generator to run in background and not blocking block\r
- placement and transfer\r
-* Make chunks to be tiled vertically too\r
+* This will be the final way.\r
+* Generate blocks in the same way as chunks, by copying a voxelmanipulator\r
+ from the map that is one block larger in all directions.\r

Misc. stuff:\r
