(and what they do) In mostly alphabetical order:

• app.h:
  • defines the application class.
  • this class looks after windowing and input, and also holds a pointer to the current scene.
  • (effectively a state machine.)
• app.cpp:
  • contains implementation of the application class.
  • constructor opens window and sets input callbacks.
  • update function checks controls and updates the current scene.
  • render function resizes the viewport, clears the screen and renders the current scene.
• bsm.h
  • header file for ROBO_DONUT's Binary Static Mesh library
  • https://github.com/ml32/Binary-Static-Mesh
• game.h
  • defines the game class, which manages the state of the currently running game.
  • inherits from the abstract scene class.
• game.cpp
  • contains the game implementation, and a few lisp functions.
  • constructor sets up the camera and loads the default level
  • level is loaded from json file inside level directory containing the level assets.
• main.cpp
  • contains main function/entry point.
  • instantiates a new app object, and calls its mainloop function.
• model.h
  • provides a wrapper class around an OpenGL IBO and VBO.
  • loaded from a filename, provides a render function that binds the buffers and pushes the geometry.
• model.cpp
  • contains implementation of model class
• phys_obj.h
  • wrapper around a Bullet lib rigid body.
  • provides a render method that draws the attached model
• phys_obj.cpp
  • physObj implementation
• scene.h
  • abstract base class that all scenes inherit from
  • has pure virtual render and update methods
  • also defines a sceneInfo struct that contains key state etc. (passed from application class)
• util.h
  • declares utility functions used by other parts of the application
  • includes functions for creating bullet meshes/hulls from BSM files, and for extracting data from JSON objects (such as vectors/quaternions, or entire assemblies)
• util.cpp
  • implements the utility functions
• workshop.h
  • declares the workshop scene, which allows users to place parts and build robots.
  • inherits from scene: update/render functions are called from the application class.
• workshop.cpp
  • implements the workshop scene.
• world.h
  • declares a wrapper around a Bullet world
  • keeps a hold of all of the necessary components, cleans them up when it's destroyed.
• world.cpp
  • implements the world class and tag dictionary class
