Adds a config setting to change the temperature at which rain and snow switch for a biome.
Minecraft lowers the temperature of a biome as the y-level goes above y=80, which means colder biomes like tiagas can start snowing once they reach a certain y-level because their adjusted temperature is low enough. This mod gives you a setting that can change the temperature value that is checked for whether snow or rain should be used.
The formula to get this value is:
snowTemperature = baseBiomeTemperature - (targetHeight - snowLevel) / 800
Where:
baseBiomeTemperature: value from thebiome.jsonfile (or wiki) for the biomes base temperaturetargetHeight: y-level that you want the biome to start snowing atsnowLevel: y = 80
Put the snowTemperature value you calculate into config/snowaltitude-common.toml
