MC 1.13 Worldgen

Overview of changes

  • net.minecraftforge.fml.common.IWorldGenerator -> net.minecraft.world.gen.feature.Feature
    • No longer needed. I think it should be removed by forge, as it has been superseded by vanilla functionality. See below.
  • net.minecraft.world.gen.feature.WorldGenerator -> net.minecraft.world.gen.feature.Feature
    • This would also be the most common replacement of Forge's IWorldGenerator. This should be the solution for anything smaller than a chunk.
    • Except the 8 blocks offset. This is not a thing anymore. Population now works just like any normal person would expect.
    • Position of features is controlled by instances of net.minecraft.world.gen.placement.BasePlacement instead of by the feature itself.
  • net.minecraft.world.gen.MapGenBase -> net.minecraft.world.gen.carver.IWorldCarver

1.13/1.14 update primer

This primer is licensed under CC0, do whatever you want.

BUT do note that this can be updated, so leave a link here so readers can see the updated information themselves.

1.13 and 1.14 are lumped together in this doc, you're on your own if you just want to go to 1.13 and not 1.14, for some reason.

1.15 stuff: https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e

Things in Advance

  • ResourceLocation now throw on non-snake-case names instead of silently lowercasing for you, so you probably should go and change all those string constants now. More precisely, domains must only contain alphanumeric lowercase, underscore (_), dash (-), or dot (.). Paths have the same restrictions, but can also contain forward slashes (/).
