TFC Seed Maker


There are 2 main reasons I'm making this:

  1. I wanted to be able to check one or more existing seeds for resoureces and/or make maps of those resources.
  2. I wanted to make a non-spoiling way to select a good seed. (aka be sure it has some decent resources within a reasonable radius of spawn, without knowing where to go look)

For info about the maps, including a color legend, see below.
