1.20 NEWS - The data pack now supports minecraft 1.20 and the files are available for download! Other versions (1.19, 1.18, 1.17, etc.) can be found on the "Older versions" link!

I'll still keep updating it when minecraft 1.21 will come out and even after for future versions, I'll also plan to keep all older versions downloadable!

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

WARNING! This data pack can sometimes be resource demanding (especially for ocean evaporation and big forests burning), but it should work on most PCs. Try lowering your render distance and reducing your graphics if you encounter performance issues.

Optifine is needed to make the resource pack work (it uses a custom sky for the sun).

You can use the data pack without the resource pack and Optifine, but the sun will be normal-sized.

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

NOTE - If you encounter issues after some time with water not evaporating, fire not raining, blocks/entities not burning, 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:

My first data pack ever created! The Solar Apocalypse data pack is a remake of the old Solar Apocalyse mod that was on minecraft 1.2.5 and earlier. This data pack will make the sun huge and deadly! The world will burn, all mobs and plants will die, all flammable blocks will burn, ice and snow will melt, and water will evaporate!

Features:

If exposed to the sky:

- every entity and players will burn to death (unless they have fire resistance effect)
- all plants will die (including potted plants)
- any flammable blocks will burn (wood, planks, leaves, hay blocks, crafting tables, chest, doors, beds, etc...)
- grass and mycelium will turn into dirt
- podzol, farmland, dirt paths and rooted dirt will turn into coarse dirt
- snow, powder snow and ice will melt
- mud and its variants dry into clay/stone
- mossy blocks will lose their moss (ex: mossy cobble turning into normal cobble)
- all sources of water like rivers, lakes and oceans will evaporate (including waterlogged blocks)

Other features:

- the sun looks 5x bigger (the resource pack is required for this)
- it rains fire and lava all around the world
- blocks and entities have to be under a solid block to avoid burning or dying, so you will need to make your base underground or protect it with a solid unflammable roof
- warped and crimson materials/plants don't burn to sunlight, so they're safe to use on the surface
- nighttime is the only safe period to explore the surface
- other dimensions are 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 to install:

To start the Solar 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!

The resource pack goes into the resource pack folder of your minecraft installation.

Planned features:

- adding progressive apocalypse stages like the original mod did, to let some time for players to gather resources before everything burns
- adding an uninstall function to remove remnants of the data pack when needed
- making a version of the resource pack compatible with FabricSkyboxes format

Issues:

- the resource pack doesn't display stars at night
- large roofs made of glass or non-solid blocks prevent some blocks below from being destroyed
- some blocks and entities aren't affected by the data pack when they're close to height limit (4 blocks or less)
- water do not evaporate correctly when it's inside an open-sky deep hole
