When I first bought my Apple IIGS last year, the first thing I sit down
to do is to write a program on my IIGS. My first only language at that
time was ORCA/M, and I try to write a set of Super Hires routines, so
that I can write a game. Yes, I can write arcade game, I have write a
complete DOS 3.3 LISA-based game before, called Infiltrator, before the
game Infiltrator was ever developed.
So when I come to IIGS, I still want to write a game. The set of routines
I designed work fine, but it flickers a lot. The standard Apple II page
flipping technique does not work, so I use an offset memory to draw the
shapes, and quickly copy it to Super Hires. But it is very slow. My demo
only runs at 12.5 frames per second, not suitable for high speed arcade
game, in which more shapes will be added to the screen. I am very sad,
since my Infiltrator, running at 1 MHz, is about twice as fast.
But lately, from this user group, I have heard about something called
'stack-animation-technique', in which I am very interested. I have no
idea WHAT is it, HOW to implement it, and hope somebody will help me. I
need to know the basic technique, some sample source code in ORCA/M,
and some clear and good advice. Perhaps one day you can find a IIGS
game programmer in Singapore, if I can master the technique.
Another question occurs to me when I am designing my Super Hires routines.
It cannot be run under Finder. But under ORCA shell, it works well. Yes,
I have change the filetype to S16, and use the QUIT code. The memory of
my program is obtained from Memory Manager, and I have start and shut down
all the tools required for Memory Manager, and I have not use ANY other
tools... perhaps under the influence of FTA. I don't use tools.
Thanks for any advice or help. Have a nice day.
