[Pysdl-devel] New PyAliens??

[Pete S. <pe...@vi...>]

well i was sitting around today, and i thought i'd try to
clean up David Clark's Excellent little PyAliens Demo.
I suppose it's an excellent demo, because it is Sam Lantiga's
standard SDL demo program for C.

Anyways, for better or worse i went and redid the PyAliens
that David Clark did. My goal was to make it a lot simpler
to follow, be more python-like, and most of all make an
actual good demo/sample for pysdl.

Well, here it is. perhaps it will get rolled into pyaliens 1.2?
I'm happy with the results, and anyone with small grasp of 
programming should be able to look at this new pyaliens and
follow along with ease.

As an added bonus, the python code is now about 30% smaller
and now runs well over the needed 50 fps to keep up with the
fps delay. (whereas my nt4-p300 was running well under 50fps
before this)

anyways, i've attached the whole thing. my main desire was
to see some code that actually could 'show off' what python
does. all the current demos and samples are pretty rough looking
and don't really show much benefit of Python over C. Hopefully
something like this can get rolled into the official pysdl
release. i'm motivated enough to clean up all the current
samples/demos and really make them shine.

anyways, i'll definitely hear anyone's suggestions. if
someone knows of another small demo like this that would be
beneficial to add the the pysdl samples let me know!

This is really excellent. The version I did was just a hacked-up,
half-C half-python experiment, but Pete's code is really very
good. It's certainly worthy of inclusion in a pysdl/demos directory,
if Mark chooses to include one. Mark?

One suggested change: On lines 224 and 228, the explosion sound is
played on channel 0, the same channel as the shot sound. As a result,
explosions quickly followed by shots are truncated. If these two lines
are changed to "audio.play(1, Snd.explode, 0, -1)" so that the
explosions play on channel 1, the two effects can overlap. 

By the way Pete, I love your docstrings :)
