-- More trees! 2013-04-07
|
|
--
|
|
-- 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.
