Stages and XML:
The definition of a stage is stored in XML (eXtended Markup Language).
The use of XML allows for a very flexible definition of a stage -- we
can define different materials, models, positions, speeds, scales,
direction, textures and shaders for the various objects in the game.
The objects consist of bunnies, walls, enemies, goals, gametiles, and
bonus items. The use of XML allows us to easily extend our game to
include multiple stages.
Using an already existing library (libxml), we parse the XML tree into
structs containing the various objects and their properties. Upon the
construction of the stage, these structs are read and converted into
their graphic counterparts. After which, the gameplay can begin.
