HammerLib Mod (1.21.1, 1.20.1) – Useful Tools, Code for Mod Developers

HammerLib Mod (1.21.1, 1.20.1) is an essential tool for developing mods easily. Packed with a lot of utilities, this library provides nearly anything a modder would need, in one handy mod. It includes features like simple annotation-based content registration, block item registration, custom block entity rendering, old-styled language parsers, mod source checks, Java-based recipe registration, tag population, simplified networking, block harvesting wrappers, NBT serialization, TileEntity wrappers, and more.

Features:

• Simple, annotation-based content registration.
• For Blocks, HammerLib automagically registers BlockItem(s). If you want to disable BlockItem(s), let your block implement INoItemBlock, ICustomBlockItem, or ICreativeTabBlock, depending on what you want to achieve.
• For BlockEntity rendering, custom BlockEntityType constants may have additional @TileRenderer, pointing to an IBESR class.
• Old-styled language parsers in format of “key=value”, instead of JSONs (the file names and format is like in older game versions, but you need to call
• LanguageAdapter.registerMod(MOD_ID); inside your mod’s constructor for it to register.
• Mod Source checks, that allow you to check if the mod was downloaded from adware/malware sites, AND warn users about it.
• Java-based recipe registration with a simple RegisterRecipesEvent, that runs on HammerLib.EVENT_BUS, allowing you, as a developer, to register crafting recipes like before, with code.
• Java-based tag population, with BuildTagsEvent, that runs on HammerLib.EVENT_BUS.
• Vastly simplified networking, using Network class, and IPacket + INBTPacket to allow for flawless and intuitive packet code development.
• Wrappers for block harvesting, that has been moved over to tags – BlockHarvestAdapter
• Field-based NBT serialization, so that you don’t make a typo/forget to write serialization/deserialization code.
• Good old TileEntity wrappers, with TileSyncable and TileSyncableTickable, that allow synchronization of initial state, as well as registering properties that will be synchronized independently.
• ContainerAPI for BlockEntities, allowing to avoid MenuType<?> altogether (no need to register screen providers, menu types etc)
  ItemStack -> Color[] API, with TexturePixelGetter.getAllColors
• Annotation-based custom model loaders (@LoadUnbakedGeometry on IUnbakedGeometry), avoids using the geometry loader class by making a common wrapper.
• …And a whole lot more!
