I'm looking for a plugin that when you place a block, only you can break it. But only admins could break any block. Example: Bob places a block. Tom comes out of no where, and breaks Bob's block. Bob's block breaks, but respawns. But remember, admins can break. Thanks for your time .
Queepo you do have a point there but he could combine it with the residence plugin http://forums.bukkit.org/threads/se...ection-system-buy-sell-land-iconomy-617.9358/ so only the creator of the residence would be allowed to build within the area. Oh but that would make unbreakable blocks unneeded if you can just protect the area with residence so Sotera try it out I use it and it works really well.
Keeping track of who placed a block for every block would generate a huge amount of data, and probably end up quickly bringing the server to its knees. Get worldguard or Towny, and learn how to use it.
