This mod is pretty simple, the only thing it does is randomize all block drops. This is the first version of this mod, the second version will be available shortly. This version randomizes block drops completely, every block can drop every other (not-blacklisted) drop. The second version maps every block to a specific drop, so a specific block will always drop a specific drop. Wood is unaffected to allow getting basic tools.
This can make for really cool skyblock, UHC, and survival challenges. It is compatible with other mods, however other mods might have issues with the way items are picked.
Mod authors can blacklist specific items or entire resource domains by sending "Randomod" an IMC message, like so:
(in init)
FMLInterModComms.sendMessage("Randomod", "blacklist", "minecraft"); //Will blacklist all vanilla items from being picked
FMLInterModComms.sendMessage("Randomod", "blacklist", new ItemStack(Blocks.STONE)); //Will blacklist stone and its variants from being picked
