[1.7.10] Can't get armor to break

[iWasHere]

I made an enchantment that goes on chest plates. It lets you fly but does heavy durability damage while you're flying. However, once the durability on the plate reaches zero, the plate can still be worn and used, and the player must either [A) throw it out of their inventory B) get hit] to have it finally break. It's really kind of annoying.

 

This is the code with the problem. Everything works just fine, but not getting the item to break/delete.

                if (ply.capabilities.isFlying) {
                    if (chestplate.getMaxDamage() == chestplate.getItemDamage()) {
                        --chestplate.stackSize;
                    } else {
                        chestplate.damageItem(1, ply);
                    }
                }

 

Does anyone have any ideas? Been stuck on this all day.

Thanks in advanced.
