1.21 NEWS - The data pack now supports minecraft 1.21 and the files are available for download! Older versions can be found on the "Older versions" link!

----------------------------------------------

WARNING! This data pack can sometimes be resource demanding (especially when large zones are being frozen, for example in new generated chunks), but it should work fine on most PCs. Try lowering your render distance and reducing your graphics if you encounter performance issues.

NOTE - If you encounter issues after some time with blocks/entities not freezing or blizzard not blowing, you'll need to reload the data pack in-game with /reload. This can happen when you teleport long distances by dying or changing dimensions.

Description:

Here's my second data pack! The Ice Apocalypse data pack is inspired of it's predecessor: The Solar Apocalypse. In this scenario, the planet earth has had its orbit modified and has gone out of the solar system, becoming a rogue planet. The world is becoming barren and frozen, temperature is rapidly dropping, the night is now eternal since there's no more sun, all mobs and plants are dying, most blocks are turning into snow or ice, and all water is freezing. You will have to go down in the depths of the world to survive thanks to the geothermal heat.

This data pack is intended to be even harder than The Solar Apocalypse.

Features:

Between layers 0 and 320:

- every entity and players will freeze to death
- all plants will die, trees will only have their frozen trunk remaining
- surface blocks (dirt, sand, gravel, etc.) will turn into snow
- all blocks not made of stone, deepslate or its variants will turn into packed ice
- all water will freeze into ice, including rivers, oceans and their contents
- all lava and magma blocks will turn into obsidian
- all non-solid blocks (stairs, slabs, door, trapdoors, furniture, etc.) will turn into air

Other features:

- the night is eternal, there is no safe period to explore the surface
- a deadly blizzard blows the surface of the world
- deepslate layers (between -64 and 0) are the only safe place to survive with the geothermal heat of the world, entities and blocks are not affected by the extreme cold at those layers
- other dimensions are also safe to explore, the data pack only affects overworld
- the data pack works for singleplayer and multiplayer (it may run slower depending of the number of players and the type of server, but it should work fine in most servers without a lot of players)

How it works:

- layers 0 to 320 aren't safe, all deadly effects take place there
- layers -64 to 0 are safe, no block or entity is affected there
- to explore the layers between 0 and 320 without dying of extreme cold, you will have to hold torches in your main hand or offhand but be sure to bring several of them as they have a limited durability, every torch lasts 20 seconds, and a stack lasts 1280 seconds (approx. 20 minutes), only torches work (for now), other light sources do not protect from extreme cold
- ores and ore blocks do not freeze so they can be harvested (ex: copper veins or gold blocks in monuments)
- all loot chests between layers 0 and 320 (dungeons, buried treasures, villages etc.) still remain so they can be looted, but once they're emptied they turn into packed ice
- suspicious sand and gravel between layers 0 and 320 remain as well so they can be brushed to get the new 1.20 stuff
- spawners between layers 0 and 320 also remain
- due to all surface blocks turning into snow, dirt and sand become a valuable resource since there's almost none of them naturally below layer 0, don't forget to gather them as much as possible as with other resources like plants, wood and food
- mobs being between layers 0 and 320 stop taking freezing damage if they stay near a player (8 blocks or less) holding a torch in their main hand or offhand
- beacons can be placed at any layer since they don't freeze, beacon pyramids can be made anywhere as well

How to install:

To start The Ice Apocalypse, just drop the .zip file in your world's data pack folder and type "/reload". Be sure to backup your saves before as the data pack does irreversible damage to your world!

Planned features:

- adding progressive apocalypse stages to let some time for players to gather resources before everything freezes
- adding progressive freezing layers, with the freezing effects being less intense the deeper the layer (currently it is danger zone -> safe zone with no gradient)
- adding other usable light sources for exploring surface layers
- adding an uninstall function to remove remnants of the data pack when needed

Issues:

- chests in layers between 0 and 320 aren't affected by the data pack if there's items inside, this is intended to keep loot chests (dungeons, village chests, buried treasures, etc.) but not for player placed chests
