Icesheet ice dungeons now have ice stairs.
Remove some now-unnecessary sandstone mapgen aliases, one
remains as it is required by the dungeon loot mod.
Re-arrange mapgen aliases to separate those needed for mgv6.
This schematic is used for sapling-grown large cacti, so should not
destroy the sand node below, as sand nodes are in short supply in
some situations.
Like trees, only force-place the node that replaces the sapling.
Previously, opening a trapdoor caused the side textures to flip.
Fix the incorrect textures.
Also add a texture transform to a tile of the open trapdoor, such
that the closed trapdoor sides use the lower part of the texture
and the open trapdoor sides use the higher part.
Clean up some codestyle issues.
In preparation for biome-defined: dungeon materials, cave liquids,
stone type, ores, decorations.
'_ocean' biomes now extend to y = -255 to be deeper than default
mgv5 oceans, and to create 'shallow underground biomes'.
Remove unnecessary biome lists for gravel and silver sand blob ores,
as those are already defined to only appear in default:stone.
Players can enter unlimited text into the field, causing lag and
potentially locking up clients. I have not found any negative effects
server side, other than the large storage needed to store the long
text.
The on_rotate function now checks the new param2 value to determine if a rotation is valid, rather than checking the rotation mode.
This is so screwdriver-like items with different rotation modes will not be able to rotate the bed into invalid orientations.
Alter 'large cactus' schematic to place another force-placed cactus node,
to replace the cactus seedling on growth.
Make schematic 5x7x5 to solve rotation, placement and protection check
issues.
Add a y-slice probability for height variation.
Growth time is tuned to not make this a faster way to obtain cactus nodes
compared to normal cactus farming.
Seedling texture by Extex101.
Use sapling/seedling description in protection intersection message in
'sapling_on_place' function.
Fixes most z-fighting caused by underwater nodeboxes.
Special tiles were for 'new style water' (lowered water level) which was
removed a few years ago.
