Temperature (Actually well made)

introduction
finally some challenge without mods don't worry it's made by a good and experienced programmer so it will be worth it

description
this is a datapack that measures the player's temperature, you can warm up with a leather chestplate or fire, and you can cool down with a turtle helmet or drink or blue fire (lanterns, torches, furnaces, campfires) it also depends on which biome you are in, the temperature is also calculated accordingly, etc. I will give a little advice and that is that in the End it is winter in the Nether it is hot good luck

How to Install
1. install this datapack
2. use 1.21 version (if You want other versions tell me in comments)
3. go to world/datapacks (server) / C:\Users\"User_name"\AppData\Roaming\.minecraft\saves\"World_name"\datapacks (sigle player)
4. use /reload command
5. if it doesn't work: if you unzip it, be careful that it's a folder in the folder

Dev Mode
just use creative if you installed datapack correctly an admin menu pops up

I forgot to add a golden carrot to the photo, but it is simply the best because it gives immunity to temperature for a few seconds
