I’ve been using this for some while now so thought I’d post the link, so those of you that haven’t already taken advantage of it can do so. It’s a standalone tile map editor that is stupidly easy to use and thanks to Nick Gravelyn’s excellent TiledLib library, stupidly easy to incorporate into your XNA projects.
Whilst it’s nice to develop your own range of development tools, I’m a big believer in making life easy for yourself where you can! Sure I could write my own tile engine in XNA or Winforms, but I couldn’t do it this well and it would take me an age…time that could be better spent on other areas of my projects.
Anyway check out Tiled and Nick’s superb library, they’re both really rather good! 🙂
