 Re: Crackers' Demo 5

Hi Mad! many thanks the detailed feedback! Well, I always with GFXs, though with less success than the experts happy

If you know the Juggler demo, in consist several full bitmaps, and just by changing the gfx map address in TED, could be easy to do full screen animation, though wasting the unchanged part.
I want to create a part that moves (rolls) the animation of a bitmap, but only a part of it, like 40x60 pixels. This is all it changes, and 5 full bitmaps in memory (90% of part unchanged) just look like a waste of disc space.
So it is 5 byte wide and 60 byte high part + the color map copy. 400 byte copy per frame is good enough, and in fact I should not change in every frame (would be too fast), so the double buffer with two bitmaps may also help.
