I'm using windows 10, installed the mod, and found out the scripts don't work.

I want to make it snow in the plains biome, so I created a configuration file in the scripts folder and in the config file I typed:
plainsbiome = forbiomes("minecraft:plains")
plainsbiome.set("temperature", 0.1)
plainsbiome.set("enableSnow", true)
then I opeded minecraft and created a new world and no changes were made to the plains biome. I am using version 3.0 of the mod.

Okay. I'd love to help, but you've given me no information.

You typed forbiomes. The command is forBiomes.

Thank you
