Hey! I’m not sure I understood what you meant. This is a free plugin, so you can use it however you’d like:)
But if you’re asking about expanding your own inventory system using this plugin, that might be a bit complicated and would probably require some changes.
However, I do plan to add a weapon system soon, so you’ll be able to use it with weapons.
