Problem with damage armor

[ColdFox]

So I've this code

if (player.isBurning()) {
					itemstack0.damageItem(3, player);
					itemstack1.damageItem(4, player);
					itemstack2.damageItem(5, player);
					itemstack3.damageItem(5, player);
				}

 

in the onArmorTickUpdate of my helmet. It works fine until the damage reaches to 0, then a new item appears and continues to damage. When I remove the new item, and them try to shift-click, it doesn't go automatically for the armor slot. Can any one tell me why aren't the items being broke?

Try removing the item if the stack's damage equals its max damage value.

Already fixed it. I searched in the EntityPlayer class and found a solution.

player.inventory.damageArmor(int ammount);
