Speaking of Neil.... here's a simple game demo with Neil running in
640x480x8bit. Neil is designed to be fast... so let me hear some frame
rates out there! Its not finished, but the simple game engine may be of
interest to some people...

2. Re: Neil demo
I get 49.7219 frames per second on my PII-300MHZ w/128MB RAM... does the video
card matter in this case? It's a Diamond 2000 3D (or somesuch thingie).
I got this screen-print when I moved the character off the right of the screen:

TEST RESULTS

My personal opinion is that the above mentioned diamond card probably has an
s-3 chip in it, which I have found to be very compatible but not very quick.
4. Re: Neil demo
Hi Everybody,
Thanks for trying out the game demo and I am *really* sorry about the
Causeway crash when scrolling to the right. Me and Causeway seem to have
a history together of not getting along... and I found the crash right
after I posted the code. I didn't have very many spinners active when I
tested it before, and then I copy/pasted the spinner sprites at the end of
test.lev to see if I could max the engine... arrrrrghhh.

The only "normal" mode in Neil is mode 19... its about as optimized as the
rest of it, but without bank-switching of VESA or the plane-switching of
ModeX. I'd like to see a benchmark of how Neil stacks up against other
gfx libs in mode 19. (oh, and Ralf - good use of the word "elaborate" 
I don't know if Einar wants this to be common knowledge, but he was using
the most recent ModeX incarnation for his new version of Hayes. The first
version of Hayes used Michael Bolin's ememcopy and mem_copy if I'm not
mistaken. He used something like command lists, where he put all the
actor sprites in a single chunk of memory and let ememcopy draw it all in
a single pass.
That is what I've based ModeX and Neil on for their command list methods.
The "execute_commands()" procedure runs all the sprite draw commands in a
single machine code call, so theres no Euphoria overhead. The commands
are kept each in their own memory space and strung together in a linked
list, so commands can be added or removed from the list with little
overhead.
Still to come in Neil: transparency and lighting effects, and the pixel
perfect collision detector.
Later,

isn't that when all of us find programming oversights? ;)

Hello,
Neil demo:
31.8748 fps
32.9546 fps
33.2819 fps
these are on a college lab computer so I don't know what its statistics
are.
Looking at this game demo has reminded me that you were wanting
some graphics for your game. I see that Noah was the only one
to supply any. I still can if you still want some.
I get the following causeway error too
(usually when I'm moving right):
