I have added a few things to Minecraft (all simple items. no machines yet)
2 new ores
The one on the left is called "Blood Ore" and it drops Blood Chunks when broken. Blood Ore can be broken with any pickaxe. The one on the right is called "Ebony Ore" and it drops an ebony ore block. Ebony Ore requires a diamond pickaxe to break.
I have added a few items as well
Ebony Ore can be smelted into Ebony Ingots. You get a significant amount of XP from smelting Ebony.
Ebony can currently only be crafted into a Pickaxe and a block (which can be crafted into 9 Ebony Ingots). The Ebony Block has a blast resistance of 100 and can only be broken with an Ebony Pickaxe.
Blood Chunks can be smelted into Drops of Blood. These are then used in a shapeless recipe with a glass bottle to make a Bottle of Blood. A bottle of blood will heal the player fully and fill the hunger bar.
Milk can be crafted into butter. Butter can be made into blocks which are extremely flammable(this series of pictures was over about 3 seconds) so don't let it catch on fire. You won't be able to put it out very easily.
Next is Cocoa Powder. This dandy ingredient can be made by putting cocoa beans into the furnace. You can combine it with butter and sugar on the crafting table to make a Chocolate Bar. Chocolate Bars will heal you 2 hearts.
Chocolate bars can be crafted into Chocolate Chunks which are going to be used as a crafting ingredient in later versions. Chocolate Bars can also be made into a Box of Chocolate which is a place-able block(be careful because they can burn up quickly, but they are much easier to put out than butter). A Box of Chocolate can be crafted back into 9 Chocolate Bars.
I think that's it for now. If i remember something, I'll be sure to edit my post to add it in.
I have decided to remove the foodstuffs and put them into their own mod and expand on the new ores and such that this mod will offer. I'm still unsure of a name and EbonyCraft is kind of already taken.
