[Coco] Coco Digest, Vol 125, Issue 24

Wayne,

Do a google search on "javascript raycasting engine tutorial" (or just 
"raycasting tutorial") - there are plenty of examples out there on how 
these engines work, and many of them are quite clear in describing the 
mechanics. In the case of the javascript versions, you can even run the 
code in your browser, and as long as your computer was made in the last 
10 years or so, it should run it OK.

The trick with the CoCo, as always - is the memory and speed limitations 
imposed by the hardware. Various tricks and techniques (and corner 
cutting!) need to be done to get any real semblance of speed for a good 
game (that, and tons of hand adjusted and tweaked assembler).

What's amazing today is what can now be done with an interpreted 
language (javascript) in the browser. Take it up another notch with 
HTML5 and WebGL hardware acceleration - and be really amazed!

Now I find that more than one person on this list has written these kinds of programs in the past, be it on a coco or otherwise.
