[pygame] PixelArray versus Surfarray + Numeric/NumPy
Hi everyone! I'm a hobby programmer and new to pygame. This is my first post to the list. I've been reading different docs and the the list archives to understand how best to move forward with experiments in image blending. The Surfarray tutorial on the docs page is excellent, but a little outdated. This seems to be a transitional period where the documentation and support for NumPy have not arrived and the pre-built Windows binaries for NumPy and Numeric don't support the latest python. As an alternative, can I just use pygame.PixelArray for all of my realtime blending needs? Is it too slow? If not, could anyone point me to some documentation on setting up a Windows build environment that will work for compiling pygame, python, and numpy together? Thanks very much for your help! Jordan
[pygame] Re: PixelArray versus Surfarray + Numeric/NumPy
Hello again. I may have posted prematurely. It seems that the easiest thing for me to do is to just set up a Python2.4 + Numeric dev environment and wait for the incompatibilities to sort themselves out. I still welcome any of your suggestions too my previous questions. Thanks again. On Mon, Jan 5, 2009 at 12:31 PM, Jordan Applewhite < jordan.applewh...@gmail.com> wrote: > Hi everyone!

Re: [pygame] Re: PixelArray versus Surfarray + Numeric/NumPy
Marcus: Thanks for illuminating the difference between PixelArray and Surfarray. I'm trying to learn how use additive blending effectively, so I think I can use either module. Patrick & Lenard: Ok, I understand now that I should just use numpy. After I looked in the arraydemo.py example I could see that the the changes needed to use numpy were not very significant. Also, I'm finding this tutorial: http://www.scipy.org/Tentative_NumPy_Tutorial#head-b43db272311d8133ab8ba29b6e8ff921da5e792d to be very helpful. It seems like numpy would make it fun and easy to dynamically operate on tile maps, in addition to pixel surfaces.

[pygame] Adding __eq__ method to pygame Event class at runtime
Hi! I thought it would be nice to add an __eq__ method to the pygame.event.Event class at runtime. This would let me use == (rich comparison operator) on events in the manner of if pygame.event.wait() == trigger_event: pass I tried to do this with setattr like so (please pardon the one-liner): setattr( pygame.event.Event.__class__, '__eq__', lambda self, other: self.type == other.type ) I've tried several variations on this idea, but the attribute seems to be off-limits. I keep getting errors like "TypeError: can't set attributes of built-in/extension type 'builtin_function_or_method'". I notice that calling pygame.event.Event.__class__ lists it as a "builtin function or method.", but I'm not sure why this means I can't create the method. Could someone please point me in the right direction? Thanks, and I'm sorry if this is more about python than pygame. I'm hoping it passes the relevance threshold:)

I'm afraid I don't have the skills to offer a patch. Oh well, there are lots of other ways to accomplish what I need. Thanks for the quick answer!

Re: [pygame] Adding __eq__ method to pygame Event class at runtime
Lenard, your patch was enjoyable to read. I guess I should be looking at the chapter "Extending and Embedding the Python Interpreter". Thanks again, you guys are great.

Re: [pygame] App Store
I've also been dreaming of a pygame distribution platform. I imagined something Steam-like that had social features like a friends list, a minimal chat client, reddit or digg-like user rating system to rank 'hotness', and the ability to invite people to multiplayer games. Also, since it seems like most pygames are FOSS, you could do neat things like p2p distribution and some kind of integrated support for mods or accepting patches. I know I went overboard seeing as all you're talking about is a package manager, but it seemed like an appropriate time to pipe up with this idea soup I've been simmering for awhile:) On Wed, May 13, 2009 at 6:44 PM, Yanom Mobis wrote: > how bout some sort of "Pygame Deployment System" like this: > > Pygame, SDL, and common libraries are built into the PDS. > > The user selects the game to download from a Tkinter interface. > > The game will be downloaded from a server.
