I have this code in a block:

 

    @Override
    public void harvestBlock(World worldIn, EntityPlayer player, BlockPos pos, IBlockState state, @Nullable TileEntity te, @Nullable ItemStack stack) {
        if(stack != null) {
            Item i = stack.getItem();
            if(i instanceof ItemTool) {
                stack.damageItem(2, player);
            }
            else if(i instanceof ItemHoe) {
                stack.damageItem(1, player);
            }
        }
    }

 

While in survival mode, breaking the block with a hoe does not result in the item taking damage. When trying to debug, the item sustains the damage, this method returns, and as far as I can tell, no longer has the damage. Any other tool only takes 1 damage (???). I can't figure out what part of vanilla is overriding this effect.

 

I know for a fact that this worked fine in 1.7.10, but I would need to go back and check 1.10 and 1.11

The ItemHoe setBlock() method also calls stack.damageItem(1, player) so you're doing same as vanilla use should do. I'm sure you know how to trace the code as well or better than me, but seems like standard stuff would prevent the damage: if the max damage is less than zero, if the NBT tag has unbreakable boolean set true, if the unbreakable enchantment is in effect, if player is in creative mode.

 

One thing though -- what material is your hoe? The ToolMaterial affects much of these fields.

The stack itself takes the damage, at the end of the above function, the stack has the desired 1 damage. When it returns (back to the InteractionManager) it does not.

The type of hoe didn't matter. I tried wooden, iron, and diamond.

Were you messing around with the BreakEvent or block harvest event and somehow canceling the damage?

Nope.

 

Looks like I can use removedByPlayer instead and that correctly deals damage to the item.
