Hey,.. Ehm I'm just creating a plugin that allows you to lock your chest, your doors, your beacon and,.. You know, everything has an inventory, but I had a flash right now, I explain. You can simply lock your chest by using a simple command and then add players to a "whitelist" this Player can destroy or place block on the top or the bottom of your chest, or simply open it (Player not whitelist cannot do that) But I wanted to add something like an hacking system (that you can enable or disable by the config) but the question is.. How can you "gain" hacking ability, for example, I have "locking ability" to 6 and a Player has "hacking ability" to 5, and cannot open or destroy your chest, but if his ability is 7 e can, now.. I Redo the question.. How do you wants your Player gain ability of hacking and looking? (two different ability that by the config you can use a unique one if you want, something like "hackLocking skills" I hope you like this idea, let me know here, I will appreciate your help and suggest. And also sorry for my bad English Thank You!!
