RE: Lunar Lander on Asteroids. :-)

Clay,
        Lunar Lander does use the same landscape over and over again.
I had thought about hacking it and making a random landscape (too bad
there's not a pokey chip on LL, since there's not one, you would have to
write a random number generator).
Another option would be to have several landscapes prebuilt and just select
from one of them. (this would be real easy, just start a counter from the
time someone puts a coin in until the game starts, then just mask off the
high bits and use the number to select the terrain)
The only thing I don't know is how they do the collision detection (as well
as the height above landscape), they either calculate it from the map or
there is a table somewhere else in memory they use that matches the map. (If
they do it from another table, it could be a real pain to change the
landscape)

Let me know if you want me to start hacking through the code (I can do this
when I get board of working on my color space wars, and when I'm not doing
homework)

Haven't fired that up yet. Will be interesting to see though. ;-) I'm
pretty good at digging through Vector ROM data now, so I can colorize
everything on an object-by-object, line-by-line basis if need be. Hmmm.
Actually it'd be kinda fun to be able to use the Saucer from Asteroids
as your "lander"... *grin*

Does LL just use that one landscape for the while game? (The wheels are
turning again... ;-)
