< in wiki?

Seems like when I post code in the cookbook with a < (less-than sign),
it gets replaced by &lt;, and then remains &lt; in the entry. Is there
something I can do about this?

RE: < in wiki?

Sounds like the problem is that the POST action on the initial submit
translates all html special characters to their "safe" equivalents, and then
when the wiki article is called for display it replaces all ampersand
characters with its safe equivalent again, ie: "<" --> "&lt;" --> "&amp;lt;"

Err... Not sure how this information will actually help (or even if it's
correct!), but I've definitely encountered that situation before (even with
my own stuff, as a result of being htmlspecialchar nazi).

Geometry engine

Hey guys,

Last night I posted to the cookbook my geometry engine. It uses
Numeric as suggested a few weeks ago to combine math to whatever
degree possible. It's still not as fast as I would like it, and the
part that checks for collision between round and polygonal objects is
still very ugly. I'd like to hear any advice or criticism you have.

Known defects:

- a function that simply says "yes, these things overlap" would be nice
- missing poly-poly collisions
- Still not fast enough!
- Could be documented better
- littered with commented-out print statements, which are the proof
that I was debugging the crap out of this thing

Thanks,

Ethan

Thanks for submitting it. There's probably some overlap with Alex's recent 
euclid module?

I cleaned most (if not all) of those out of the code when I also edited it for 
readability:

- wrapped the code so it was a reasonable width (if the code is wider
  than the textarea box then it'll push out the width of the resultant
  page too much, and will also be harder for casual reading)
- put a space after the comment chars (as per PEP 8)
  http://www.python.org/dev/peps/pep-0008/

(I perform these edits for all submissions to the CookBook that need them)

To some extent. Euclid supplies more geometric primitives, but what I
posted does more in the way of collision detection. Computing
collision between two polygons by computing distances between line
segments is kind of hacky.

I saw, thanks.

flip() and opengl

  | What does the flip() function do exactly, in OpenGL mode?

flip() toggles the buffer but on _some_ OS's it also _waits_ until the
screen is being displayed.

On windows, the _max_ fps I can get is 75 because thats
what my monitor operates at and opengl's flip() waits until the
monitor is displaying the buffer i just flipped to.

On unix, the same code can get 200+ because it doesnt wait for
the montior to display (but my monitor still works at only 75 fps,
so those extra updates dont get me anything). (Except maybe glitches
if I flip mid frame.)

Check out page 22 of the red book, "The Refresh that Pauses".

weird refresh error

hi all

I am getting a refresh error on linux (tried couple of machines) and on 
a windows machine with Nvidia card. I run my app and it is ok but if 
another windows overlap the pygame window, after that the area that was 
overlapped does not refresh anymore. Up to tomorrow I thought this was 
something to do with linux as on my windows machines runs fine, but 
yesterday I tested it on a friends laptop and I got the same error.

I am using pygame + pyOpenGL.

sounds familiar to anyone?

thanks!

It's not an error ;)

You will need to redraw the part of the window that was covered. There is a 
specific event you can receive that tells you when you need to perform this 
action.
