I am trying to repair my weapon with a custom item and I thought I had it figured out but it is not working.  What I am I missing? I didn't copy over the whole class just the relevant bits, here is what I have so far:

 

ModItems.class:

public static final ToolMaterial metalLvl1 = EnumHelper.addToolMaterial(Reference.MODID + ":metalLvl1", 0, 120, 2.0F, 1.2F, 5);

public static void init() { 
		
		metalLvl1.setRepairItem(new ItemStack(ModItems.copperIngot, 1, 0));	
		swordCopper = new ItemWeapon(metalLvl1, "sword_copper");
		
	}

This works great for giving me the correct durability and damage for my weapon but the repairing does not work.

 

Here is the ItemWeapon.class:

public class ItemWeapon extends ItemSword{

	public ItemWeapon(ToolMaterial materialIn, String name) {
		super(materialIn);
		setUnlocalizedName(name);
		setRegistryName(name);
		this.setMaxStackSize(1);
	}
	
}

 

When is init called relative to your item constructors?

If you answer "I don't know" then you're doing everything wrong.

That was enough to help me figure it out. Thank you!
