Note: the instructions at this link are good but things have changed a bit for Forge 1.7: http://www.minecraftforge.net/wiki/Crafting_and_Smelting

Different types of mods require different types of code. One of the easiest type of mod to add is a crafting recipe. We will write one to turn some dirt into diamonds.

The code for this goes into the init function:

What this does:

• Create a new ItemStack called dirtStack with a single dirt block
• Create a new ItemStack called diamonds10 with 10 diamond blocks
• Add a new recipe to the game that will produce this stack of 10 diamonds, when you lay out the dirt in the shape specified: x in the shape is where the dirt blocks have to go.

We can also have shapeless recipes (where it doesn’t matter where you put blocks), which are even simpler to write:

GameRegistry.addShapelessRecipe(
new ItemStack(Items.diamond, 6), new ItemStack(Blocks.dirt));

This second one creates a stack of 6 diamonds from a single block of dirt.
