Temperatures

The mod assigns a temperature to each biome, and that value shifts between day and night. Rain and snow change the temperature a player feels, and certain blocks can raise or lower it nearby. Temperature is split into four levels: normal, uncomfortable, and two extreme levels, burning and freezing. A player can only enter uncomfortable temperatures after gaining one level of cold or heat protection, and the extreme levels need a specialised protection named Icebreaker or Flamebreaker. Burning happens at once in the Nether, while freezing sets in when a player goes into water or cold regions.

Protection can come from potions, such as Fire Resistance, or from enchanted items like a Cold Resistant chestplate that grants the Cold Resistance effect. Enchantments and potion effects cannot be stacked together, following the Zelda model. Temperatures is intended as a block progression tool, keeping players out of specific biomes and dimensions until they have the right gear. The mod is open source under the GNU Lesser General Public License v3.0 only, and it runs on client and server with Forge.
