sprites suck.

There are now sprites. kinda.

 

Except the drawing-list computations have obviously got a major error, because what should complete inside of 5 scanlines is taking more like 100 on (every other field?)

 

And I'm pretty sure the drawing is incorrect inside the kernel too, but the timing isn't tweaked yet so it looks all sketchy anyways.

 

Tonight I might get time to frell around with this properly.

 

(Looks like one of those bpl/bmi stupid things that mess with me. Screenshot didn't catch the sprite field no matter how many times I tried :-( but there's a black rect flickering around looking like a trapezoidy thing in the midst of the crazy rolling.)

Happy debugging! ;)

 

Indeed.

 

As my deadline looms, this drawing-list stuff is increasingly getting marked as "features for the 1.1 release" and some sketchier but easier to debug stuff getting pushed into its place. :-(

 

Imperfect code that mostly works is better than optimal code that mostly doesn't. Or something.

 

EDIT: To clarify, that is: If you don't have time to debug, rewrite it more simply and save a draft.
