Well, I've been working on this for a while now. I originally drew the
very basics of the non-score part of the screen with the java tool I've
been working on. After getting a basic file to work with, I began
editing code. What I've got now is a scoreboard, and a playing field
that scrolls up and down depending on where the bouncing PF Ball is
located on the screen. I'm at a point now where I feel I can ask for
some feedback. Pushing the left fire button starts the PF Ball moving.
I'm curious to know if what I've made looks the same on a real 2600, so
if someone with a cuttle cart has some spare time it would be great if
you could try it out on the real system for me. What I notice so far is
that I have too much code upfront handling the ball bouncing/PF
scrolling. This causes the screen to jump up a scanline when the button
is pushed. I tried some of the techniques suggested for code
optimization listed on the dig. Specifically the JMP(indirect) code, but
I haven't had much luck and only seem to make the problem worse. So I
left that code out of this version.
What you'll see if you run the attached bin is the basics of a game
intended to be similar to the game Quiditch found in the Harry Potter
books. Some of you may remember that I announced that I'm working on
another game: KC-135. It's still on my list of things to do, but I found
that I needed to hone my skills on a simpler game before I go back to
that one. That's why I'm working on this Quiditch thing. Anyway, any
feedback anyone has to give would be greatly welcomed.
Thanks,
Aaron
