I'm currently looking into adding a secondary 'Test' world for my server. Here's the idea: The test world would be a rather large flat smooth stone terrain in which players would be able to build/test certain structures for the main world. I have a few questions before I look more into this: 1. Would the 2 worlds effect each other in ANY way?(ie. Would players have 2 seperate inventories for each world?) My main world is a fully legit vanilla style world, I'd like to keep it that way. 2. I'd like the test world to be a flat terrain of pure smooth stone, how could I achieve this? 3. I'd like the test world to reset back to default/empty world every X hours/days to prevent people greifing, or staying/living in this world. Is this possible? 4. I'd like the test world to be in creative mode, with the main being in survival as it currently is. Possible? Thanks for all the help in advance. Please bear with me, I'm pretty new to running a server or anything like this. I hope you understand what I want. -Dan P.s: I'm sorry if this is posted in the wrong section/context. I was unsure on both the section and the title.
