Modding utils used in my mods, which I thought could be reused. Feel free to use in your own mods or fork/copy what you need.

Roughly accurate list of utils in this library. Categories correspond to packages in the source code.

• QualifiedNameArgumentType Argument type accepting qualified:resource_names

• ColorUtil Measure color distances, find closest dye/formatting color, mix and interpolate colors, and other miscellaneous color utils.
• ForgeUtil
  • futureNotNull Placeholder for Object Holder initializers
  • getSerializedCaps Extract capabilities NBT from ItemStack
• LogUtil Log once utils.
• ObfuscationReflectionUtil Failure tolerant reflection utils.

• Interpolator Very basic interpolation functions for animations.
• MathParser Very inefficient math parser with support for custom variables and functions.
• MathHighlighter Add syntax highlighting to the expressions parsed by MathParser.
• Vec3d and Vec3f Custom vector implementations with many rotation utils.

• JsonToNBTUtil Self documented name.
• NBTPath Navigate NBT using dot-separated paths. Can create intermediate nodes, and works similarly to IO paths.
• NBTPredicate Serializable NBT predicates, such as {Fireworks.Flight >= 3}. Supports lists and complex predicates, though it's not perfect.
• NBTCompareHelper Utils to compare NBT on specific paths.

• PacketBufferUtil read/write nullables, lists and maps.
• ClientPlayerPacket and ServerPlayerPacket Base class for packets carrying a player reference.
• DistributedPlayerPacket and ValidatedDistributedPlayerPacket Special client player packet, that is automatically relayed to other players (usually those tracking the player). The server can prevent this behaviour ofc.
• ServerWorldPacket Base class for packets carrying a world reference to the clients.

• NBTInheritingShapedRecipe Base recipe class that can specify (using upper case letters) items in the grid which are used as NBT sources for the crafting result.
• RecipeManagerHelper Utils to get registered recipes.

• AudioUtil Fading and cross-fading utils.
• PlayerTickableSound Base class for TickableSounds associated to a player.

• MutableComponentList List of MutableComponents that can broadcast formatting operations to all its elements. Convenient for text split in lines.
• TextUtil Aliases for TextComponent and TranslationComponent constructors, split text components into formattable lists on newlines (including translated text (on client)), and link creation utils.
• TooltipUtil Key hints in tooltips.

The following events are injected by this library's mixins. For reference purposes, the mixins that fire these events can be found in the endorh.lazulib.mixins package.

• CancelCapeRenderEvent Hide a player's cape conditionally.
• DisableElytraCheckEvent Conditionally tweak or skip the elytra speed check in servers for players.
• GenerateEndShipItemFrameEvent Modify the item frame containing the elytra in end ships. The handler for this event in Aerobatic Elytra exposes this event to datapacks through a loot table.
• PlayerTravelEvent Modify the movement physics of the player.
• RemotePlayerTravelEvent Modify the local movement physics extrapolation for remote players.
• PlayerTurnEvent Modify the logic controlling the player's rotation.
• RegisterTextureAtlasEvent Inject custom texture atlas into the ModelManager's AtlasSet.
• SetupRotationsRenderPlayerEvent Modify the rotations applied to the player's model.
