As the title implies, the items i have made has durability that shows, but it only takes durability the first time i use them. Not too sure why it only takes one off of the whole durability so i would like some guidance on this topic. Thanks in advance! ^^

Edit: I fixed it, looked into what setdamage did and realized that it actually didn't remove durability but actually just set the durability to a certain number.

Item#setDamage sets the ItemStack's damage to the specified amount. You call it with 1, so it sets the ItemStack's damage to 1.

 

The method you want is ItemStack#damageItem, which increments the ItemStack's damage by the specified amount. Calling with 1 will add 1 to the damage.

 

Side note: Don't use Item#setDamage directly, use ItemStack#setItemDamage when you want to set the ItemStack's damage instead.
