Tree Tweaker

Tree Tweaker is a CraftTweaker addon that allows you to add custom trees to world generation. The shape, height, leaves, logs, frequency, biome, and more can all be customized through zenscript. Trees can use modded blocks and be set to generate in modded biomes.

newtree.setMinHeight(INT);

set the minimum height of the tree. newtree.setMinHeight(5);

newtree.setExtraHeight(INT);

newtree.setGenFrequency(INT);

Used to control how often a tree generates, successfully spawning at a rate of 1 in N attempts newtree.setGenFrequency(5)

newtree.setGenAttempts(INT);

How many trees should try to spawn during a successful generation attempt. Can be used to make clusters of trees newtree.setGenAttempts(1)

newtree.extraThick=boolean;
