The tnt:boom node doesn't actually need the on_construct and on_timer functions to remove the node after 0.4 seconds as the tnt_explode function already does this beforehand.
Liquids that are 'igniters', such as lava, will drop the torch without
a flame-extinguish sound, as the torch item will burn up after a few
seconds with a sound and smoke particles.
All other liquids cause a flame-extinguish sound.
Only register floatland biomes if mgv7 'biomerepeat' flag is false.
Simplify floatland biomes to coniferous forest and ocean.
Make 'mgv7_floatland_level' and 'mgv7_shadow_limit' parameters global
values for mods to use to register their own floatland biomes.
Previous times were chosen using statistical maths, but reports suggested
this was too long.
I tested by timing an ABM acting on 100 nodes, with interval and chance equal
to the old sapling ABM.
50 at 4m59s.
99 at 24m58s.
100 at 26m58s.
So choose a grow time between 5 and 25 min for tree and bush saplings.
If 'can grow' is false at grow time the timer is reset to 5 min.
This allows us to preserve mgv6 ore distribution while giving us the freedom
to alter ore distribution for other mapgens.
Other mapgens are larger scale and have 3D noise tunnels which make vertical
travel easier, so ores can be deeper.
Other mapgens have registered biomes which allows us to limit ores to certain
biomes.
It is useful for protection mods to know who owns an exploding
TNT block. This allows the blocks destroyed by the TNT to be
limited to the same ones the owner could destroy without using
TNT.
TNT placed within a protected area by the area owner, and later
ignited by another player will destroy within the protected area
nodes the igniter may not otherwise be able to interact with. Any
player could significantly increase the size of an explosion by
placing more TNT in an adjacent unprotected area if the original
TNT block was placed withing 1 node of such a boundary. This
feature sounds dangerous, but we are talking about TNT. Players
should use it carefully.
If backface culling is not specified for a tile in 'images' it is set to true.
Slabs already have backface culling due to being defined as nodeboxes (which
are then converted to meshnodes).
Really large books just waste hard drive space and the engine is not designed to
handle that much data in item metadata, this can cause strange things to happen.
No longer have 2 recipes for stairs, choose the one that matches the appearence
in inventory (stair rising toward the right).
Helps to reduce recipe count now that an increasing number of stairs are
being registered.
