Saplings can dynamically generate different trees, based on the biome they are grown in, declared in data files.
Description
Ever played with a mod, such as Terralith or William Wythers' Overhauled Overworld, that add custom trees to world gen that you can't grow?
With Treeplacer you can create a custom datapack that allows you to change saplings to grow into whatever tree your heart desires!
Features include:
Change a sapling's tree for all biomes,
Change a sapling's tree based on biome,
Change a sapling's tree based on the block it is grown on.
Define a 2x2 tree that uses the rules above on all saplings, even mushrooms!
To get started take a look at the wiki on github.
