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 I think it should be removed by forge, as it has been superseded by vanilla functionality.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
• This is now finally exposed to mods in a useful way. As it was mostly hidden from modders before, not eveyone may know what it is, so it will be explained later. Generates caves a

With the release of Forge 14.23.2.2638, a proper way to render items with GL was implemented. Using this system is much simpler than the old system, which required a TileEntity, and does not allow access to the ItemStack.

Using TileEntityItemStackRenderer

TileEntityItemStackRenderer allows you to render your item using public void renderByItem(ItemStack itemStackIn).
There is an overload that takes partialTicks as a parameter, but it is never called in vanilla.

In order to use a TEISR, the Item must first satisfy the condition that its model returns true for IBakedModel#isBuiltInRenderer. Once that returns true, the Item's TEISR will be accessed for rendering. If it does not have one, it will use the default TileEntityItemStackRenderer.instance. For an example IBakedModel to use, see below.

In this document, I use strings in the format "foo:bar" to represent ResourceLocations with domain foo and path bar. I also use [square brackets] for placeholders.

The Model Loading Process

Blocks

On startup and whenever the resources are reloaded (in ModelLoader#setupModelRegistry), Minecraft iterates through every registered Block (in ModelLoader#loadBlocks) and asks its custom IStateMapper (or DefaultStateMapper if none has been registered) to create a mapping between every valid IBlockState of the Block and the ModelResourceLocation for that state (with the domain and path pointing to a blockstates file and the variant to a variant within that file). It then attempts to load these models.

DefaultStateMapper looks for the blockstates file with the Block's registry name (i.e. assets/[modid]/blockstates/[name].json) and serialises each property and value of the IBlockState to create the variant name that the model is loaded from (e.g. "enabled=true,type=foobar"

Capabilities...a wondrous new system. That you've probably been forced into using. But let's not talk about that and get straight into the learning!

Terms and definitions

• Capability System - This entire system; what this primer is about. This system is named very literally for what it does.
  • Capability - the quality of being capable; capacity; ability
• Capable - having power and ability
