alright, thanks. think I have everything sorta out now. wanted to set up a small creative server for me an my ffriends so we could work out our plans for a sky city we're building on a servival server. I want it above an ocean so if you fall while building out the floor you don't fall to your death where someone could then pick up ur stuff. but then if you make a mistake and have to break some blocks to fix it, they fall into the ocean and you can't really get them back. the server is servival as I mentioned so you have to take the time to gether everything nessesary for building, includding all the blocks ur gunna use. and since the city if gunna be huge and you gott build the ground to, that's a hardly imaginable amount of blocks. can't afford to loose tons of them in the ocean all the time. and the floor being smooth stone means if you break them they become cobble and you'd have to melt them down again. raods are cobble, so you gotta be paying attention when you build and really know what and where your building.
and on a creative server just for us we could screw around and screw up as much as we want/need cause of corse we got infinite supplys, no melting down. and can make as meny mistakes as we want/need. then once we got it all worked out and all know what we're doing and how to do it, we can do it right on the servival server.
so yes, this has been a BIG help to me, so thanks again
