Matt can you expand on this for me, sorry im really new at this.

here the code that ive written. this is my main function, all i want it to
do right now is start witha black screen fade the yaroze scene logo in,
leave it for a few seconds and fade to black, then after that just show the
logo as normal. ( the last bit would be where a title screen or something
would go i guess.

im just trying to understandhow all this stuff works. as you will seee im
still just learing the structure of all this stuff, it hasnt quite clicked
yet, VSyncs, DrawSyncs etc are still playing with my head a bit.

thanks

greg

void main (void)
{
 int vsync = 0;       // vertical screen sync
 int BufferIndex;      // buffer index
 int frame;

 Initialise();

 InitSprite((u_long *)YAROZE_SCENE_ADD);

 BufferIndex = GsGetActiveBuff();  // Returns either 1 or 0,

 GameState = RUNNING;

 while(GameState)      // Check that we are still playing the game
 {
  switch(GameState)
 {
   case RUNNING:       // The Normal GamePlay


   break;

   case TITLESCREEN:       // The TitleScreen

   for(frame=0;frame<=60; frame++)
   {
       sprite.r -= 1;
    sprite.g -= 1;
    sprite.b -= 1;
    VSync(0);
         }
  GameState = RUNNING;
     break;

   case PAUSE:       // Pause Command
  break;

   case GAMEOVER:       // GameOver
     break;


  }



   DealWithPad();

   GsSetWorkBase((PACKET*)packetArea[BufferIndex]);

   GsClearOt(0, 0, &WorldOT[BufferIndex]); //clear out the present OT ready
for drawing

  // now lets set up the image
  GsSortFastSprite(&sprite,&WorldOT[BufferIndex],0);
  // register the sprite in the ordering table


   DrawSync(0);
   vsync = VSync(1);
   VSync(0);  // get the vertical sync interval

   FntPrint("HSYNC: %d\n", vsync);

   ResetGraph(1);

   GsSwapDispBuff();
   GsSortClear(0, 0, 0, &WorldOT[BufferIndex]);
   GsDrawOt(&WorldOT[BufferIndex]); // draw the current off screen buffer to
the screen

   BufferIndex = BufferIndex^1; // change side to 1 or 0
   FntFlush(-1); // print all font calls
 }
 ResetGraph(0);
}
