Building Game Maps: My Bookmarks
Via Twitter, @tjgillis asked his followers for any links on building game maps. I’m still planning to do a more in-depth article on programming game maps for browser based games but for now I’m sharing these bookmarks. This list is only about a few aspects of programming game maps so if you have any questions please leave a comment, I’ll be happy to answer it.
