Comment on Playing a sound in pygame by Wian Rifqi Dwi

Wian Rifqi Dwi — Fri, 20 Jul 2012 15:17:09 +0000

Sir, my name Wian..
Could I ask you some question?

This’s about playing the sound using Python with Pygame..
I’ve already did what you post here, I’ve changed the filename to my ‘real’ sound WAV name..
Using quote ‘gameover.wav’ inside the bracket after the pygame.mixer.Sound() & the variable name after try:

And the result it do nothing but the error appear because not using pygame.quit & sys.exit..

What should I do then, I’m a newbie..
Please guide me

Comment on Cairo with python Ctypes by Stu

I still need to try on ctypesgen in windows vs linux to see if thats the reason for the difference in ctypesgen.

Do you which .h files, it might be possible to just pass those to ctypesgen.

I noticed that M_PI is included from math.h an used in the tests, I’ve successfully replaced it with math.pi in testing.

The ctypesgen loader doesn’t seem to understand ubuntu style ld.so.conf files containing wildcards, so this is what I’ve been looking at, hopefully can get this working and upstream next.

Ok.
I use only ctypesgen SVN version, but last changes is from Feb.24.2012 http://code.google.com/p/ctypesgen/source/detail?r=141.
If you know more recent (young) version, send me link please.

Also I must warn about my hand additions – it is some necessary functions from other “.h” files, for work with PNG surface.

Hi Maxim,
Your Enlish is fine
I’ll have a look at the changes when I get a chance. The issue I was having on 64 bit ubuntu seems in ctypesgen svn.
Can you try regenerating cairo.py with svn ctypesgen, that should be the same as the when I generate it in ubuntu and ‘just work’.

The subversion ctypesgen.py is a bit simpler: ctypesgen.py cairo.h > cairo.py seems to be enough to get working bindings.

It’s probably an idea to not modify cairo.py, so that it can be regenerated without breaking anything.

Hi Stuart.
Thanks for bug reports and patches again, I will work under these.
Consider load Cairo library – I made some changes after ctypesgen was generated, first change is on 595 line of cairo.py, now it have _CAIRO_LIBRARY_ variable and may be used in users py file
(or test.py) as first line of code before import cairo “import os; os.environ['_CAIRO_LIBRARY_'] = ‘full_path_name_to_custom_cairo_library”.

Sorry for my English.

PyIrricht looks nice, I haven’t checked out game engines for while.

Cheers for adding setup.py and the other changes.

I did some testing in linux, but hit a bug in the ctypesgen generated code.

http://code.google.com/p/cairo-ctypes/issues/detail?id=5

I’ve got ctypesgen on linux here, let me know if there are any tests I can do to try and find the source of the bug.

Thank you for your reply.
I understand about classes, see my pyIrrlicht project, but should be noted that, Cairo purely functional (cairo-ctypes auto-generated, respectively), and object approach requires more time to develop and direct (individual) developer, but my main project pyIrrlicht.

I also use Cairo for rendering SVG in irrlicht_c.dll and I’m very important analogue of Cairo in Python, for study and testing.

Thanks for the tips on googlecode, I made some corrections.

Hi Maxim,
Your library looks useful, it’s slightly different to this one at the moment – yours provides the cairo C.

What I’m interested in is providing the pycairo API where you get classes for things like Context, Surface, ImageSurface etc.

This is achieved by importing a ctypes style binding then using metaclasses to bind the functions to classes using their names (e.g. a prefix of cairo_image_surface_ goes to ImageSurface).

I could save a lot of the nastier code by just building on your library.

I haven’t worked on this for a little while though so feel free to take the ideas/code. A pycairo compatible library might be useful for running pycairo style code on pypy for instance.
