Ok, so I wasn't about to build a game (way too busy) but I did need to get this map importer working so I signed up just to force myself to get moving on it.
I'm using Monogame and wanting to lay down a good framework for myself to build games, but importing maps from spreadsheet data and whatnot is not cool. Especially when there are a few good editors out there. So I had a hunt around for the easiest way to do it. So many ways to skin a cat.
I found the Monogame Extended libraries and they were just what I was after. Naturally the documentation is a total crapshoot. I pieced it all together though, took me about a day of swearing and trial and error. I've got both orthometric and isometric maps working.
Anyway, I've just discovered I can't post images because of some stupid karma system.
What a waste of time this was.
