In the code over at
<http://kschnee.xepher.net/code/070530ShiningSeaSource.zip> there's one
file, "nixie.py", that might be useful. It's messy, but it's got code for
tasks like loading animation frames from a single character sheet (with
any size or padding) and the logic of animation sequences. "coral.py" is a
tile engine that changes the sprite locations based on the location of a
hypothetical camera.

Recently I tried reducing the size of the tiles I was using, and I found
that the character seemed to move more slowly. It was a pleasant surprise
to figure out that the character was covering ground at the same rate,
because the "world coordinates" of the character were unaffected by the
size of the graphics.

What I've tried to do is have what I call a "worldsim," the Model in MVC,
that tracks the game's characters and environment. I test that out in
plain text. Then I build a Display class (the View), and give it access to
the Model. The Controller part of MVC might be built into the View too.
The upshot is that I've then got an object that's the Model, that's
accessed by the View/Controller. Doing that means the graphics engine can
be replaced relatively easily. It can be awkward, though, since the Model
needs some way to send messages to the main class like "the player got
killed."
