Native plants

This mod makes it so that saplings and plants can only grow in their native biomes. For example bamboo will only grow in bamboo jungle.

You can plant saplings for trees, but they don’t grow. When they try to grow a few seconds after planting, they will drop as if broken.

It can support both modded plants and saplings if they grow similarly to the vanilla saplings.

This mod can be configured via datapacks.

Halfway through making this mod, i found out that the mod Biome Growth Controls By Lothrazar exists. https://www.curseforge.com/minecraft/mc-mods/restricted-saplings

I could learn from the source code, for, for example the specific mechanics on cactus. If that mods gets an update, I would use that mod instead of this one.

Something I would like to add in the future is an item, that can be used to find out where a plant can grow.
