Detailed Description

Spiral Walker.

Version

v.3 (2012-01-28)

Author

W. Minchin (MinchinWeb)

Since

MetaLibrary v.4

The SpiralWalker class allows you to define a starting point, and then 'walk' all the tiles in a spiral outward. It was originally used to find a build-able spot for my HQ in WmDOT, but is useful for many other things as well.

Note

SpiralWalker is designed to be a persistent class.
