WorldGuard Polygon Generator is a plugin which allows you to easily create custom WorldGuard polygonal/cuboid regions, all with a few simple commands. The possible shapes include, but do not limit to: circles, ellipses, squares, rectangles, triangles, diamonds, squares, pentagons, hexagons and octagons. The commands are very flexible, allowing you to creates millions of different shape combinations.
These shapes represent regions which have been generated using WGPG. The regions have been illustrated using Dynmap and Dynmap-WorldGuard.
This plugin requires WorldGuard and WorldEdit.
