RandomLib

(This will likely be replaced later by a github repository)

RandomLibUtils.setup during FMLCommonSetupEvent to setup your config files.

<T extends ExtraData> RandomLibUtils.setup(ResourceLocation registryKey, Supplier<T> extra, Consumer<Map<String, RandomPool<T>>> afterDeserialization)

As an example, your config files will be generated in configs/oneblock/phases/ folder if registryKey = oneblock:phases.
extra is a supplier for an instance of an ExtraData implementation. This allows you to save more information about a random pool, in addition to the weighted items.

Once your config files are deserialized, they are saved in a map with their file name as a key but you likely would like to store them in a more convenient structure for your mod using the afterDeserialization consumer.

RandomLibUtils.registerCommand during FMLServerStartingEvent to setup a command to manage config files generated by RandomLib.

RandomLibUtils.registerCommand(FMLServerStartingEvent event, String commandname, ResourceLocation registryKey)
RandomLibUtils.registerCommand(FMLServerStartingEvent event, String commandname, ResourceLocation registryKey, ExtraDataCommand<? extends ExtraData> extraDataCommand)

RandomPool#getRandom()#generateAndReplace(ServerWorld, BlockPos)  to destroy block and generate an item from the random pool in the given world at the given position.

RandomPool#getRandom()#generate(ServerWorld, BlockPos)  to generate an item from the random pool in the given world at the given position.

RandomPool#getRandom()#vgenerate(RandomContainer, ServerWorld, BlockPos, ItemStack)  to generate an item from the random pool for an object implementing RandomContainer (likely a tile entity) in the given world at the given position and for the given held item (if any).
