Hi! I am coding a plugin that is called Soul Trade. (it is being coded in spigot 1.13.2). The whole purpose of the plugin is that you can deposit player heads into a currency. And when I mean player heads I mean that I am using a mobhead plugin that drops player heads when killing mobs. The thing is that the player heads that I want to deposit is just not just basic ItemStack.player_heads, I want the plugin to be able to retrieve the player heads NBT tags from the players inventory and then set as some kind of variable to be able to remove the custom player head from the player inventory. Is this possible and how? Is there another or is my question way out of reach to understand? I hope if my question is understandable to help me because I am trying really hard to explain what I want my plugin to do. Please be kind with your explanation's if you want to help me because I am quite bad at spigot coding (I tried to learn it some years ago but to no avail, but now I have been giving it another chance).
