All i need is a plugin that protects in a circular radius for my circular spawn that disables pvp inside the area maybe some simple flags, ignores world guard over it and that's all.
Yes it can. Read up on this: http://wiki.sk89q.com/wiki/WorldEdit/Selection Then claim the region with WorldGuard
You cannot CLAIM a region with //sel Sphere you can only claim a region with world guard with //sel cuboid and //sel poly. Can someone actually help?
Yes you can, it automatically detects that it is a circle region when you claim it and saves it like that. If that doesn't work for you then I don't know whats happening.
Can't claim spheres or cylinders, but polygons work fine. Since Minecraft is in blocks, spheres are nothing more than polygons with many sides. Select with sphere, then switch to polygon and WorldEdit will convert your sphere selection to a polygon automatically.
