Hi there, does anyone know if it is possible to replace the Bukkit ItemStack with a self constructed ItemStack? For example I have a CustomItemStack class that extends the Bukkit ItemStack class and overrides getMaxStacksize(). But when I give the player the CustomItemStack (add it to inventory) it is replaced by the Bukkit Item Stack. Is it possible, thru NMS hacking or Protocols to pass thru my own item stack and have that getMaxStacksize() method carry thru? Thanks in advance for any help!
