From Bukkit Objects

Players

Due to legacy reasons, WorldGuard uses its own internal player object called LocalPlayer. A Bukkit Player can be converted to a LocalPlayer using wrapPlayer(Player) on WorldGuardPlugin.

getWorldGuard().wrapPlayer(player);

Vectors

Many operations need WorldEdit vectors. Bukkit Locations can be converted to Vectors using methods on BukkitUtil.

BukkitUtil.toVector(location);
