So, I have recently been developing a survival server in which there is a custom world, and in which players go out into it in order to claim land and build houses, shops, and ect. The problem is, I am unable to find any land-claiming plugins that fit the vanilla-minecraft theme of my server. The type of plugin that I am interested in is one in which a player can craft an otherwise-unobtainable object, (Ex: a sponge) and within a certain radius of where that block is placed, is their claim.
I have looked at the Grief Protection plugin, but it doesn't fit what I am looking for my minecraft server. If you know about a plugin or could make one, I would appreciate it if you could give me some feedback.
