Re: [pygame] pygame for portable python

[René Dudfield]

Yeah cool.

I think it will give me a good push to finish off more tests as we change
towards py3k.

The sprite module is missing tests for a lot of the older sprite
functionality.  So that's the major one of the .py files I think.  Our build
scripts, and tests are the other major .py files.

If we start back porting some of the pgreloaded py3k stuff, then I think we
can have a pygame 1.9 prerelease for py3k within 4 weeks time(in time for
the course).  Remember, it only took Marcus a few days to port pgreloaded.


cheers,

Re: [pygame] PyConsole IN Pygame?

[René Dudfield]

Hi,

there are some consoles around... search on the pygame website.

An ipython based one would be awesome.  Note, that pygame has clipboard
support since 1.8, so would be good for selecting/copying text and such.
Also copying in image data from an editor(gimp) and pasting it into the
console - assigning it to replace in game graphics from the clipboard!

Would be great if we had a nice working implementation.


cheers,

Re: [pygame] Networking library

[Patrick Mullen]

Python2.6 comes with json.  Other than that, it is a small thing to include.

The library seems to be built around json, so removing it as a
dependency doesn't make much sense.

I took a look at this library when you announced it and thought it
looks good, but I haven't had a chance to really try it out.

The whiteboard example is very impressive!  It looks a lot easier to
start working with than twisted.

Re: [pygame] GSOC: Extending Camera support for PyGame to Mac OSX Updates!

[Nirav Patel]

A kalman filter is I think implementable in numpy without much
difficulty, and numpy is already a dependency.

It depends on what you are looking for, but searching Google Scholar
on a specific topic is a great way to learn about various algorithms.

Re: [pygame] move problems

[Zack Schilling]

Tuples are immutable. Strictly speaking, that means that their  
structure cannot change after definition. In practical use, tuples  
will contain ints, floats, or strings, all of which are also  
immutable. Since you can't change an int without "replacing" it, you  
can't change an int in a tuple without replacing the whole tuple.


tl;dr: You need to either recreate the tuple or use a list.

[pygame] Networking library

[Chris McCormick]

Hi All,

I posted this as a project page on the pygame website, but I'm not getting much
traction with my library, so I thought I'd post it here to see if anyone is
interested.

Basically it's a [hopefully] super-easy-to-use networking library that works
well with Pygame too. Included is a simple networked whiteboard demo written in
pure Pygame.



Have fun, and please let me know what you thik, or if you find bugs, or need 
help.

Best,

Chris.

[pygame] PyConsole IN Pygame?

[Campbell Barton]

Hi, have been writing basic console in blender3d's game engine but I
was thinking that anyone else trying to write an in-game console (like
in quake :) ) would have to do almost the same things.
There is just some differences when you are getting events directly,
and having to do a basic readline style line editor in python which
could be generic between blender3d or any other engine.

Requirements are that you can get events, render text and store the
console object between execution's.

I was wondering if anyone had written a python console in PyGame? or
could it be useful to port as a testcase?

Summary:

Nirav Patel has recently implemented camera support into pygame as  
a way to
interact with a game. However, this camera module is limited to the  
Linux
platform. The goal of my project is to extend this camera module to  
the Mac
OSX platform, and thus extending the portability of games written  
in pygame

that use a webcam as mean to interact with the player.

I will be using the OSX QiuckTime multimedia framework to work with  
the
camera. The camera module shall be implemented in C as a python  
extension.
It is my intension to fully port the capabilities of the existing  
camera
module. If there are any existing capabilities in the QT Isight  
framework,

that could be useful to have in the pygame module, I will make these
available by writhing a wrapper around them.

I will use pyobjc to experiment during the project. For the final  
code I

will use objc and C wrappers,since pyobjc is no longer used in
pygane.

When I am finished implementing the camera module for OSX, I will  
work on
optimizing the existing code, like optimizing the sbggr8_to_rgb  
function.
Ather this I will write documentation and a simple game to  
demonstrate the

capabilities.

I am planning to make a branch of my code available on github.com so
everybody who like can follow my daily work on the project.

Re: [pygame] pygame for portable python

[Andre Krause]

hi René,

first, i introduce them to k-turtle, a logo variant and the probably most
easiest way to get into programming. moving that turtle on-screen and drawing
simple geometric things is quite intuitive.

then, after 4 sessions ( 1 session per week) i switch to python using python
portable. python portable is fantastic: i can put it on a network drive, they
can put it on their usb-stick and do their homeworks where-ever they like and
dont have to install anything.

after some python basics (what is the interactive command line, how to print
hello, how to add some numbers, how to calculate a mean value over numbers etc)
i just start over with turtle using pythons turtle graphics. this is good - its
a recapitulation and they might get the idea that you can do same things with
different computer languages - so it doesnt really matter what language you
actually speak.

so - i understand your point that most modules are not yet python 3 ready,
but i only use pyturtle and pygame. and its a very basic total beginners course,
 so they wont encounter any great differences between 2.x and 3.0 in codebooks,
as i only teach very fundamentals like variables, loops etc. its a course for
university freshman.

ok, long writing, short message: i would need pygame for 3.0 in about 4-5 weeks.

thank you very much !
