I want to say when itemBalloonSword breaks to give new Itemstack itemDeflatedBalloonSword but have no idea how any help would be greatly appreciated.

It's a sword used to kill mobs I need to replace the item once it hits 0 durability or breaks

I got the same problem with another item. on certain events the item gets damaged and when the the durability is 0 i want to remove the item, but i have no idea how to do that

You can try to check if the sword is about to break(only 1 damage left to break) change the item.

Probably in onUpdate() method.

 

I think you cannot check if its breaks or hits 0. Although im not sure.

 

Is there something like getDurability and I can say if it's one to replace the item?

if(par1ItemStack.getItemDamage() == par1ItemStack.getMaxDamage() - 1){

//Replace item

}

 

This should do the trick.

Thank you so much I have been stuck on this for the last couple days

You should note that sometimes, durability reduces by two, such as when you break a block with the sword, you can overcome this by overriding onBlockDestroyed with the same code in ItemSword, but you replace the item once the durability hits getMaxDurability - 2 instead of damaging the ItemStack. Like so:

 

@Override
public boolean onBlockDestroyed(ItemStack stack, World world, Block block, int x, int y, int z, EntityLivingBase entity) {
    if ((double)block.getBlockHardness(world, x, y, z) != 0.0D)
    {
        if (stack.getItemDamage() == stack.getMaxDamage() - 2) {
              // replace item and return true
        }
        stack.damageItem(2, entity);
    }
    return true;
}

Yeah right, but then you should not use "==".

Use >= instead.

Sorry guys I'm kinda new to this I tried putting it directly in the ballonsword class and it did not work

Did it crash or just nothing happened

nothing happened no errors or crashes

I don't think I'm replacing the object correct how would I do that?
