CDX Game Development Library
Created by Dan Farley. Current Version by Bil Simser
CDX is a free GDK (Game Development Kit) which is comprised of a set of C++ wrapper classes for writing Windows games. It is built on top of Microsoft Windows and DirectX technology and offers simple to use C++ wrappers for all aspects of game development.
This includes things like sprites, tiles, scrollable maps, alpha blending and even 3D primitives (using Direct3D). CDX takes care of the low-level details of using DirectX, providing you with an easy to use toolkit for implementing your own games using simple yet flexible C++ classes. With only 2 dozen classes, CDX is a powerful tool yet easy to use and quick to learn.
CDX is released under the Perl Artistic License. Read it if you aren’t sure what you can or can’t do. The bottom line is that this is a kinder and gentler version of the GNU license — one that doesn’t infect your work if you care to borrow from CDX or package up pieces of it as part of a commercial product!
