View source for Unification Initialisation

The [[Unification]] '''main''' function uses the [[gameTools]] 'gameStarter' function to handle the signon screen and all of the user interaction necessary to get things started.

  const char *initialLevel = gameStarter ( argc, argv,
                                "unification", getenv ( "UNI_DATADIR" ),
                                UNI,
                                78.0f/255.0f, 14.0f/255.0f, 99.0f/255.0f ) ;

Then we initialise the random number generator using the time-of-day clock so no two games are exactly the same:

  srand ( (unsigned int) time ( NULL ) ) ;

Finally, we call the 'init' functions for all of the game subsystems:

  initClock         () ; showGLerror ( "After initClock" ) ;
  initScreen        ( UNI ) ; showGLerror ( "After initScreen" ) ;
  initCamera        () ; showGLerror ( "After initCamera" ) ;
  initEvents        () ; showGLerror ( "After initEvents" ) ;
  initObjects       () ; showGLerror ( "After initObjects" ) ;
  initGraphics      () ; showGLerror ( "After initGraphics" ) ;
  initSky           () ; showGLerror ( "After initSky" ) ;
  initDatabase      ( initialLevel ) ; showGLerror ( "After initDatabase" ) ;
  initParticles     () ; showGLerror ( "After initParticles" ) ;

The '''showGLerror(...)''' function helps to track errors in each of the subsystems that might cause an OpenGL error - which in turn messes up shader compilation and loading.
