Wow! Each one of those titles looks great!

 

May I beg and ask that you finish Frenzy first? It is one of my all-time favorites and your mock up looks incredible!

Nice!

Thanks, guys

cool your doing Battlezone!!! Is it going to be a XM game??

It would have to be for the extra memory. I have the screen set up as a line buffer from the bottom of the score area down. I have a line drawing routine that is a bit slow ATM.

 

Thanks!

Looking forward to seeing Battlezone in action! Keep up the great work!

I have a line drawing routine that is a bit slow ATM.

 

The line routine is still on my list of things to help you out with. I was looking at it again the other day.

One line drawing algorithm I learned from T.A. Goldthorpe

 

dx = x1 - x0
dy = y1 - y0
qx = abs(dy) // note the reversal
qy = abs(dx)
q = min( qx, qy )
cx = x0
cy = y0
do
 plot( cx, cy )
 qx = qx - q
 if ( qx < 0 )
   qx = qx + abs(dy)
   cx = cx + sgn(dx)
 endif
 qy = qy - q
 if ( qy < 0 )
   qy = qy + abs(dx)
   cy = cy + sgn(dy)
 endif
while ( cx != x1 && cy != y1 )
plot( cx, cy )

 

Note: this is from memory / off the top of my head. I remember the basic idea, but have to work out the details anew each time I want to use it. Another line drawing algorithm I created myself was recursive binary subdivision.

Thanks, Eric - I'll give that routine a try.
