-- More trees! 2013-01-20

|
|
-- 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.
|
|
--
|
|
-- Conifers and Jungle tree axioms/rules by Vanessa Ezekowitz, with the
|
|
-- latter having been tweaked by RealBadAngel, most others written by
|
|
-- RealBadAngel.

|
|
-- local test = perlin1:get2d({x=pos.x, y=pos.z})
|
|
-- if smooth and (test > 0.73 or (test > 0.43 and math.random(0,29) > (0.73 - test) * 100 )) then
|
|
-- in_biome = true
|
|
-- elseif not smooth and test > 0.53 then
|
|
-- in_biome = true
|

-- end
