A simple and efficient interface for using a multi-level matrix of values.


CMapEditor is a simple and efficient interface for using a multi-level matrix of values. This can be easily used in games or any other program that requires a versatile map structure.


How to use CMapEditor:

#include "CMapEditor.h"

Include the .h file in your code. Keep also in mind that CMapEditor requires the <vector> header to be present on your machine.

To initialize a map just use:



CMapEditor *meEditor = new CMapEditor(WIDTH,HEIGHT,LEVELS);

To set a cell's value in the map, use:


You can also use advanced operations, such as region fill, or drag-like procedures:




CMapEditor also supports basic undo and redo operations. You can decide what is going to be undone by calling


before performing other operations. For example:


in this case, the SetMapValue() and the Fill() effects will be undone together. To perform undo and redo, just use:




Why did I write this class

Actually, the purpose of this class was for me to learn. And I did. As a matter of fact, class programming was a bizarre way of thinking about stuff before, therefore, I decided to start from the basics, and started learning about that. OK, I got the basics, but if you have any comments on how I programmed the class, please let me know. Secondly, I wanted to get familiar with Hungarian notation (all my other projects are big messes), so if you have comments also on that, let me know. And finally, I learned how to use vectors, which I didn't expect to use (actually, I didn't even know what thery were) and they seem to be pretty useful. Another reason for which I decided to write this class, is that I wanted to contribute something hopefully useful to CodeProject.


  • Last Update (15 Oct 2003)
    • I have fixed some memory leaks issues. Now the class destructor is correct.

Simple and elegant. And good formatting of the article. One thing--I get a "file corrupt" error when I try to download the source. Any ideas?

Keep up the good work!
