Hi Thomas! >I prefer this version, the ships now behave more realistic. You >also might be able to reduce the PF width a bit, aren't you? So the current choice is between 2 options: 1. Doing it with the PF, as shown in the quick hack. Pros: - No kernel cycles required Cons: - It'll probably be assymetric. The left part is eaten up by the HMOVE lines and when reducing the size, the stars come out on the far right edge. - It's eating a few pixels more than required. - The color of the cockpit, crosshair, stars is all the same. - I need to change the priority register. The stars are _always_ above the sprites then. 2. Doing an ANDing logic inside the kernel Pros: - No cockpit drawn (Hey, to me this'd be a "pro" :-)) - None of the Cons of the PF solution Cons: - Kernel cycles required (I don't know wether it's doable at all...) - The starfield is displayed on the whole screen, but the sprites would start disappearing earlier on the borders. Might look strange.
