Hey everyone,

 

I want to make a custom tool that loses durability when either, right-clicking a specific block, or breaking any block. (I can do basic block checks here) The main thing I'm struggling with is actually removing durability from the tool, and registering it correctly. I currently have a tool that extends ItemTool and have registered it. Just having trouble setting and removing durability.

 

(I know this is probably super wrong what I'm tying to do here) Bottom code crashes immediately when breaking a block, a null pointer on something called getStrVsBlock() .

 

Item Carving Tool:

public class ItemCarvingTool extends ItemToolBase {
    public ItemCarvingTool(String name, float attackDamageIn, float attackSpeedIn, ToolMaterial materialIn, Set<Block> effectiveBlocksIn) {
        super(name, attackDamageIn, attackSpeedIn, materialIn, effectiveBlocksIn);
        setMaxStackSize(1);
        setMaxDamage(15);
    }

    @Override
    public boolean onBlockDestroyed(ItemStack stack, World worldIn, IBlockState state, BlockPos pos, EntityLivingBase entityLiving) {
        stack.setItemDamage(stack.getItemDamage() - 1);
        return false;
    }
}

 

Item Tool Base:

public class ItemToolBase extends ItemTool {
    public ItemToolBase(String name, float attackDamageIn, float attackSpeedIn, ToolMaterial materialIn, Set<Block> effectiveBlocksIn) {
        super(attackDamageIn, attackSpeedIn, materialIn, effectiveBlocksIn);
        this.setUnlocalizedName(name);
        this.setRegistryName(new ResourceLocation(Reference.MODID, name));
    }
}

 

Register item:

public static final Item carving_tool = new ItemCarvingTool("carving_tool", 2.0f, 2.0f, Item.ToolMaterial.IRON, null);

To damage the itemstack, call ItemStack::damageItem instead. It automatically handles breaking when durability <= 0 & deals with statistics as well.

 

You also need to provide an empty Set<Block> instead of null when instantiating your ItemCarvingTool.

 

Ah, I see. Alright, gonna try that out

Awesome, it is working perfectly.
