Subject: Re: MM/JSW walking and jumping rules
1. Do lots of experiments to determine the jumping-rules in a
systematic manner (with heavy use of the pause-button).
I've been using video grabs for much the same thing. I have a series
of jump and move tests and each build had to perform the same.
2. Invert all the pixels in the player's sprite-page
Ah, I hadn't thought of that one. Thanks!
3. (Possibly) Study the game-engine disassemblies
This is the route I've decided to take. I've annotated a good quarter
of the jump routines from MM so far - I'll share the results once I've
finished (and I'll give the same treatment to JSW afterwards).
4. Check for conformance with quirky features:
I'm hoping that with a pretty straight port of the original code
it'll quite faithfully reproduce most of them without much extra
effort. Possibly!
Carl.
