Hi, I am currently trying to create a plugin that can be used to instantiate worlds per player or group of players, kinda like the World of Warcraft instance system. I am trying to make it so that you can select a region with WorldEdit and then create a separate world out of that selection, which will be used as the "template world" and copied over if a player starts the instance. The problem I have is that somehow the copied world is always full of void chunks. I am using a custom WorldCreator to make new chunks void, but I dont know if this will make existing chunks void too? I am using the WorldCreator.copy(World) function and then a copy of the WorldBorders trim task to trim out the chunks. Does anyone have an idea how to make this work or how to copy and trim a world in general? Thanks in Advance!
