The are two parts that make up an Orx game. The code and the data configuration.
Of course, there's code. Orx is for C or C++ developers. Using code you (of course) develop your game. But, you can also use configuration data in config files.
Data Configuration (or config) is one or more text files containing sections with properties and values:
[ExampleObject] Graphic = ExampleGraphic Position = (320, 240, 0) Rotation = 45
These sections can be objects, sounds, textures, physics, timelines anything in the Orx subsystem.
You can do an amazing amount in the config with very little code needed. Config is there to help you as much as possible.
