This is a mod powered by Mixin which enables localization of hardcoded texts.
It means replacing static in-code texts with language keys, so they can be translated with a language Resourcepack.

This mod:

Adds missing localization functionality to MC 1.12.2
Localizes hardcoded texts in many mods.
Includes lots of lang keys not originally included in Minecraft and many mods.
Bonus: Applies little QoL fixes in some mods (this is not the purpose of Localizator, but I just HAD to fix them).

On first run, all Mixins are disabled by default.
You can enable all Mixins if you want.
If a corresponding mod doesn't exist in your instance, its Mixin won't load and everything will run as expected.

(Minecraft) Sometimes Mod Developers and Modpack creators like to add "Novelty/Collectible Items" (Items with custom Name and Lore) to add some fun to the game.
Some of those items are placeable (Blocks, Paintings, Signs, Skulls). And if players place them, the items lose their NBT tags (Vanilla behaviour), turning into normal items.

FAQ:

Why did you change dependencies?
Originally, I depended on MixinBooter to load Mixins, and managed the access to other mods by myself.
The code for accessing other mods is extremely Mixin version-dependant, so if a new Mixin update releases, Localizator would most likely crash until I find a way to adapt the accessing code to the new Mixin version, and my response time would be long.

Fonnymunkey's FermiumBooter also manages the code for accessing other mods, and fonny is way more capable of adapting this code for future Mixins versions, resulting in very short response times.
So by depending on FermiumBooter, I can focus on my own Mixins, and leave the access code to a more experimented developer.

I hope you understand.
