Just Enough IDs is a simple mod that allows you to bypass the limits on the number of block, item, biome, potion, and enchantment identifiers in Minecraft. It uses the new chunk format of 1.13 in version 1.12, including the block state palette when saving chunks in NBT and an int array for biomes instead of a byte array.
When using JustEnoughIDs with other modifications, some incompatibilities may occur; however, if you encounter such a problem, please report it in our issue tracker. Unlike the NotEnoughIDs mod, removing JustEnoughIDs does not corrupt worlds created with its use.
It is very important to remember that removing JustEnoughIDs may damage your world. This is equivalent to loading a 1.13 world in version 1.12! JustEnoughIDs cannot load worlds created using NotEnoughIDs.
FAQ
1. Is the mod compatible with other mods?
Currently, JustEnoughIDs is incompatible with The Lost Cities mod, but future versions may be compatible. Some mods may require additional support due to the specifics of the biome array operation in version 1.12. If you experience issues with biome rendering or command functionality, please report them in the JEID section on the F3 screen.
2. Will my old worlds work with JEID?
Yes, your old worlds will work. The chunks will be updated to the 1.13 format upon loading.
3. Can I convert my NEID worlds to JEID?
No, it is currently not possible to convert worlds created using NotEnoughIDs to JustEnoughIDs worlds. However, you can use both mods simultaneously. In this case, JEID will disable block and item limit fixes to allow NEID to work with them, but it will keep the biome limit fix to maintain compatibility with previous worlds and use any number of biomes.
4. Will this mod damage my world?
No, JustEnoughIDs is a correct implementation of NotEnoughIDs. Just because NotEnoughIDs was unable to implement a safe identifier limit extension system does not mean it is impossible. Mojang did this in version 1.13, and JustEnoughIDs simply ported the features of the 1.13 chunk format to version 1.12. Please do not consider this mod bad just because of issues related to NotEnoughIDs.
