Idfix Mod 1.13.1/1.12.2 for Minecraft


About Idfix Mod:

There are two mods in this post. They both attempt to resolves ID conflicts for blocks and items for mods, but in different way.

Idfix overrides Id values at the very core of Minecraft objects, in constructors, which, while effective, may have undesired effects: a mod would request to create a block with an Id of, say, 500, and created block would get Id of 4095, because Idfix overrides it to prevent a conflict. Most mods can handle this situation just fine, but some break in most unimaginable ways. Another disadvantage of Idfix is that it overrides the whole configuration system: you have the idfix.txt file with actual block/item Ids, and whatever is written in mods configuration becomes almost irrelevant.
The mechanism of Idfix mod is taken directly from ID Resolver by ShaRose.

Idfix Minus is the new iteration of the Idfix mod. It overrides the (broken) Minecraft Forge Id resolving algorithm. With Idfix Minus, all fixes to block and item Id conflicts go directly to mods config files. Its called Idfix Minus because after the conflicts are resolved, you can remove Idfix Minus mod, and things will keep working. The downside of Idfix Minus is that it doesnt fix conflicts for mods that dont use forge configuration module. The good news is that I have not been able to find one.

Idfix Minus creates a list of all items/blocks Ids named idfixminus.txt. The existence of this global file is what allows to fix the not working Forge ID resolving algorithm. When all Ids are esolved and written into mods configuration files, you can remove both the Idfix Minus mod and idfixminus.txt file. But, if at later point you want to add another mod to your set, you have to have both Idfix Minus mod and the idfixminus.txt present. So its a good idea to keep the latter forever. In case idfixminus.txt is lost, you can regenerate the file by running minecraft with Idfix Minus installed: do that before adding new mods.

If you dont know which version you want, get Idfix Minus.
In any case, dont install both.
