Re: Formula Nibble driving game

There are several type in programs in the Nibble magazine.

One is a track maker.  It reads in DATA statements and POKES to RAM,
then saves the tracks.

one is a bitmap maker.  it reads in data statements and pokes them to
RAM.  Bitmaps of grass, center dotted line, gauges, steering wheel.

One is a "screenshot" maker.  It draws the car, etc, and saves
the HGR screen on disk.  It makes two screenshots, one with
tire "squiggles" and one without.  The game updates one screen, flips
the softswitches to display it, and then updates the other screen,
flips the screen again.  Because two screens were drawn, one with
different tire features, it gives the appearance of the tire
'spinning'.

The screenshot maker produces nice green grass...  I don't know why you
get green/purple grass.  I do too.  I think I mistyped the bitmap for
the grass.

It is a very neat game.  The entire road area of the screen gets
updated each frame, byte by byte.  The posts get painted right over the
top.  You can paint anything over the screen (IE, ORA a bitmap to it)
after the road is drawn, and it will automatically be erased the next
frame.

I just found some other software I need to add 3-d vehicle to the game.
 I'll post my progress soon.
