Ok. I am really confused why this didn't work. public boolean hasContainerItem(ItemStack stack) { if (stack.getItemDamage() < maxDamage){ return true; }else{ return false; } } Is it because I'm not using the original method? Or am I wrong there?

I fixed the second issue, I hope. I can now craft and it takes damage but when it reaches 0, my client crashes. I didn't really understand which ItemStack that I should use .copy() on. Sorry to bother you so much but I really want to learn this package net.be.mods.item; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; import net.be.mods.MainModBE; import net.minecraft.client.renderer.texture.IconRegister; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; public class toolJewelChisel extends Item { private ItemStack emptyItem = null; private static int maxDamage = 64; public toolJewelChisel(int id) { super(id); setMaxDamage(64); this.setMaxStackSize(1); this.setCreativeTab(MainModBE.BETab); this.setNoRepair(); } @Override public boolean hasContainerItem() { return true; } public void setEmptyItem(ItemStack ei) { this.emptyItem = ei; } public boolean doesContainerItemLeaveCraftingGrid(ItemStack par1ItemStack) { return false; } @Override public ItemStack getContainerItemStack(ItemStack stack) { int dmg = stack.getItemDamage(); if (dmg == maxDamage) { return null; } ItemStack tr = copyStack(stack, 1); tr.setItemDamage(dmg + 1); return tr; } public static ItemStack copyStack(ItemStack stack, int n) { return new ItemStack(stack.itemID, n, stack.getItemDamage()); } @SideOnly(Side.CLIENT) public void registerIcons(IconRegister iconRegister) { this.itemIcon = iconRegister.registerIcon(MainModBE.modid + ":" + this.getUnlocalizedName().substring(5)); } }

Thank you! But now there is a new problem... The item does not dissapear when used to 0, it has 0 uses left and I can still use it infinitly. I'm kind of new but I understand most of what is going on but this has me rendered helpless... Some help would be awesome:)

Hey! I have a problem when crafting with a damaged item. I have it so my chisel takes damage when it's undamaged but after it's damaged I can no longer use it for crafting.
