Look at the bow's source.

Fair enough.

Do something like

if(Minecraft.getMinecraft().thePlayer.inventory.hasItem(ItemStack))

{

Minecraft.getMinecraft.thePlayer.inventory.getItemstack(ItemStack).stackSize--;

}

I'm on mobile so the names aren't 100% accurate

Btw to make a new ItemStack do

ItemStack yourItemStack = new ItemStack(net.minecraft.src.Item.TNT;
