About this project
What does World Evils add?
World Evils
Terraria's Corruption, Crimson and Hallow in Minecraft! (Its not exactly the same)
Your world gets one of the two evils. Which one is decided by the seed and you don't get to choose. every world is a Corruption world or a Crimson world, never both. You'll
find out which the first time you open the right chest in a nether
fortress.
Inside there are seeds. Plant one somewhere you don't mind losing, or in your friend's base to troll them :)
It spreads!
it spreads slowly. You'll plant it, nothing much will happen, and you'll forget about it.
Then you come back from mining and your whole garden is purple and thorny.
It takes almost every block, including artificial ones.
It also keeps going while you're not looking. Walking away doesn't pause it.
(There's a page in the options menu if you'd rather it went easier on your
hardware. Cap it, let it throttle itself, or switch that off entirely.)
What lives out there
Things that used to be something else, mostly. (Almost) Anything standing on infected
ground long enough transforms into whatever the infection has a use for.
There are altars in the caves, the only place evil gear can be made. And you may find other floating things, just be careful how many you break in a row.
Bring a fishing rod at some point, there's good fishies on infected waters ;)
The Hallow
Every world has it, and its seeds aren't in
the nether. Look in ominous trial chambers instead.
Plant it and you get the opposite of everything above. Light blue grass, trees that
can't pick a colour, water that went completely magenta, and crystals in the caves
doing your torch's job for you.
It's also where the mod stops being nice about it. What lives in the Hallow hits
harder than anything in the Corruption or the Crimson, and it expects you to turn
up in gear you took off them first. Wandering in wearing iron is a decision you get
to make once.
It's got two big ones of its own. One of them you can set off completely by
accident, so watch what you swing at.
By default all three keep to their own blocks and won't eat each other's. There's a
switch in the options if you'd rather they fought about it.
Requires Fabric API, Satin and GeckoLib, and Melody if you want music.
All music is a cover of its terraria counterpart, in piano. Credits to Re-Logic and its peak music.
If you use Xaero's minimap, everything in here has an icon for it.
