moretrees/init.lua
Vanessa Ezekowitz 6da6bda95e made leaves depend on the trunks they spawn with to avoid decaying
rather than just any trunk being enough to stop just any leaves from decaying.
Re-tuned the leaf decay interval/chance values accordingly.  Changed a few
variables to avoid possible conflicts.  Added a setting to allow one to disable
the new leaf decay code.  Moved sapling growth code into its own file.  Minor
changes to comments here and there.  Got rid of simple trees list (made the
code do various checks in realtime instead, since it's just startup code
anyway).  Fixed messed-up crafting for jungle trees; condensed most of the
crafting code into main craft registry loop.  Mostly fixed broken aliases of
default jungletrees.

-- More trees! 2013-02-11
--
-- This mod adds more types of trees to the game
--
-- Some of the node definitions and textures came from cisoun's conifers mod
-- and bas080's jungle trees mod.
--
-- Brought together into one mod and made L-systems compatible by Vanessa
-- Ezekowitz.
--
-- Firs and Jungle tree axioms/rules by Vanessa Ezekowitz, with the
-- latter having been tweaked by RealBadAngel, most other axioms/rules written
-- by RealBadAngel.
--
-- License: WTFPL for all parts (code and textures, including those copied
-- from the jungletree and conifers mods) except the default jungle tree trunk
-- texture, which is CC-By-SA.
