The plugin logic I want to talk about is simple. Npc is created with Citizens. Adds support for Griefprevention or any similar plugin. Farms (cactus, sugarcane...) made by the players are stored virtually in the area where the npc is located. 1. Collected items can be sold automatically. 2.Mobs from spawners die automatically and items store npc 3.Stocks are added with the help of the plugin gui 4.Cosmetics are added. Players can edit npc with citizen Plugin advantages do not drop any item, the lag problem caused by the differences is solved. Easier for players Unfortunately, I have little knowledge of plugins. I am trying to code myself. Anyone who wants can take this idea and code the plugin.
