Hello plugin makers. I have been looking around here and seen some very nice plugins, Some I have used and others that looked like fun things but a bit over powered. Anyhow I am looking for a plugin that I suppose is probably a command line that is run when there is no one on the server as this plugin will cause a MASSIVE amount of lag. I need a plugin that when you run the command will change every block of one type into another type. For instance turns all grass into netherrack. Configurable so you can change the block to change from and too. So you could do.... Leaf block into air block Gold into stone ect ect. This would be for use with plugins like boarder gaurd/world gaurd ect. The idea is when 1.8 hit we will be generating a new map, setting the bounderies with worldgaurd or similer, then removing all grass and leaf blocks. Were going for a apocolyptic landscape that supports no life (animal wise) and players go out build up towns/cities and start to take our world back from the nether invasion. Thanks in advance A though occurs, getting the server to do it all at once might be a bit much for any server, so maybe theres a way for it to do it chuck by chunk. ?
