Now 651 is history I thought it may be of interest to go through how some of the parts work.

Let's start with the boring bit for today, the actual structure. To make testing it easier, and to be able to swap and change the order to make sure it felt right, I used a pretty simple yet modular approach,

//------------------------------------------------
// Demo classes
//------------------------------------------------
        private var logo:Logo;
        private var credits:Credits;
        private var twister:Twister;
        private var vectorBalls:VectorBalls;
        private var pimp:Pimp;
        private var showReel:ShowReel;
        private var water:Water;
        private var fin:Fin;
        
        private var sequenceOrder:Array=new Array("logo","twister","vectorBalls","pimp","credits","showReel","water","fin");
        private var sequenceOffset:int;

The sequenceOrder array kinda speaks for itself. The other part of the code is just as straight forward:

//---------------------------------------------------------------------------------------
        public function sequence():void{
            switch (sequenceOrder[sequenceOffset]){
                case "logo":
                    logo=new Logo();
                    break;    
                case "twister":
                    twister=new Twister();
                    break;    
                case "credits":
                    credits=new Credits();
                    break;    
                case "vectorBalls":
                    vectorBalls=new VectorBalls();
                    break;    
                case "pimp":
                    pimp=new Pimp();
                    break;    
                case "showReel":
                    showReel=new ShowReel();
                    break;    
                case "water":
                    water=new Water();
                    break;    
                case "fin":
                    fin=new Fin();
                    break;    
            }
        }

//---------------------------------------------------------------------------------------
        public function finished():void{
            if(++sequenceOffset==sequenceOrder.length){
//Finished            
            } else {
                sequence();
            }
        }

Each segment is totally independent, ie it has it's own init and housekeeping routines, there's no co-dependency at all. To start the demo the sequenceOffset var is set to 0 and then the sequence() method is called.
When a segment has finished, it calls it's houseKeeping() method to dispose of all the bitmaps and removes all the sprites from the stage, and then calls the finished() method ( Hence it being public ).

That's all there is to the underlying structure which runs the demo, it really doesn't get any more straight forward.

Squize.
