I want to make a Mod that adds Platinum the Game.
There are a few things I wanna know:
Q. How do I make Platinum "Mineable" only with a Diamond Pick?
Q. How do I make Crafting Recipes for things like: Platinum Pick, Axe, Shovel, Hoe,
Sword, Armor, and a Platinum Block?
Q. I wanna make a Platinum Tool last 2x longer than ANY Diamond Tool? (Including Armor)
Q. How do I set a certain amount of Time it takes to Mine the Platinum Ore?
Q. I want to make a Platinum Pick mine everything 2x faster than a Diamond Pick

I have the Textures for everything already.
Will someone answer those questions for me though?
