Hello, Im currently working on an RPG that I plan on making online. I want the game to be completely customizable (like Playerworlds) but better in some ways. I was wondering how I would go about making a map editor. I see some people do it so that all it does is copy and past images together and it saves the whole level as an image, but, I want mine saved as a text file that has code for each block (32x32) on the map. I was just wondering on how this was done
