Map Editor

[Hate_Theory]

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

I've got something close to what you want, but it doesn't have scrolling implemented and it uses BitBlt.. the maps are made in the program, but I'm sure that with minor adjustments, it could also be made to get put into text files.. See attached file:

Do you need help with just the editor?
Or also with implementing the map in the game?

How does the map in the game work?
What does the map contain?
How is the mapfile formatted?

Is each block 32x32? Or are there 32x32 blocks?
What is stored for each block?
