MelonLib
MelonLib is a library mod for the mods of MelonStudios. Alongside various utility tools, like StackPredicates, StatePredicates and the RenderMelon, there is also a built-in BlockDictionary.
Thats right: OreDictionary, but for blocks!
Anyone is allowed to use this for their mods; in fact, it is greatly recommended to make sure that the block dictionary system will be a second nature of 1.12.2.
