Re: sprites... Re: [pygame] Google Summer of Code 2010 is coming
Thank you for telling me. As far as possible I just wanted to use the old sprite code. What I thought I would do is try to build these as enhancements, rather than replacements, to the existing sprite system, so that they can be easily plugged in or out. In a few days, I will finish one of the modules as an example. Nikhil Murthy On Tue, Mar 2, 2010 at 12:50 PM, René Dudfield ren...@gmail.com wrote: Hi, just a note... Jason M. Marshall has recently been working on the sprite code. That doesn't stop you of course, just to note that he has been working on it.

About Me: Name: Nikhil Murthy E-mail address: murthynik...@yahoo.com, murthyn...@gmail.com Time Zone: IST (GMT+5:30) Preferred Language: English Other Time Commitments: None Pygame Experience: - Prototypes for 6 different games, one of which won a prize. http://www.gamecareerguide.com/features/581/results_from_game_design_.php?page=1 Programming Experience: - Summer internship with Dhruva, a Bangalore-based video game company. - An economic simulation for a professor of my college - The registration software of the Department of Controls of my college. About My Project: What I wish to do is improve the sprite and scene system of pygame. The aims I wish to achieve are: - Provide a highly flexible set of utilities for quickly making games with pygame. - Have every component be easy to remove and replace by a user written module. To do this, I will make modules for the following basic components of games: - Views: Parts of the screen which display different logical parts of the game - Game spaces: For collision detection. - Game states: To keep track of the state of running of the game so as to easily and reversibly alter state. - Images: To make resources more natural to deal with and provide a common base so that using a rabbyt back-end can be done without changing any game code. These are the components I always felt to be lacking in pygame, and that I feel will be of use in almost every game, so I would like to work on these. For each of these modules, I will: - Write and submit the implementation - Test against a number of unit tests and as a component of a small game. - Document every class and function. - Present the test game as an example of best practices with the module.

Taking up the ball, I think, it would be great to have another Google Summer of Code for Pygame. Since we had a good success with the last ones and all mentees did a great job so far, with lots of new stuff being contributed and quite some fun, it would be nice to participate again. I'll be definitely up for mentoring this year (with less time to spend, but even more motivation :-), though I personally would not want to have Pygame trying to apply as own organisation this year. We failed last year and Arc Riley from the PSF did a great job to manage anything for participating projects under the PSF umbrella. It is more likely that we will participate successfully with the PSF, especially since we would have more time to manage the student's work, which otherwise would have to be spent on administering. Anyways, volunteers, students, interested mentors, core devs and anyone else, get ready, fasten your seat belt and bring up your own ideas to have another great coding season. Interested students can find the ideas page for pygame as well as more information regarding the summer of code in the pygame wiki: http://pygame.org/wiki/gsoc2010ideas The ideas are only ideas, not guidelines to what will be accepted. If you have an own idea for Pygame, feel free to post it to the mailing list and let's discuss it. Regards Marcus
Re: [pygame] Unprintable characters
Clean slate. UniCode does not seem to be completely functional in SDL. As this thread from 2006 suggests ( http://old.nabble.com/Arrow-Keys,-and-keysym.unicode,-SDL-1.2.10-td5030718.html) you may need to do some platform-specific special handling of certain keyboard events. The SDL version used in Pygame may have changed in the last four years, but the behavior does not indicate so. Of course, there is still the possibility that I am a floundering UniCode noob. I'm sure one of the Pygame devs could clarify. Check this out. ##begin python## import unicodedata import pygame from pygame.locals import KEYDOWN pygame.init() pygame.display.set_mode((10,10)) while 1: for e in pygame.event.get(): if e.type == KEYDOWN: print 'key', e.key print 'unicode len', len(e.unicode) print 'unicode name', unicodedata.name(e.unicode, 'no name') print '--break--' ##end python## The following output is on a Compaq 6910p Windows XP laptop, Python 2.5.4, Pygame 1.9. I can't explain why Python's name lookup is failing on a carriage return, or why the two Intel platforms I have access to (Windows and Ubuntu) return an event.key that is greater than an 8-bit value for cursor keys. ##begin program output## key 32 unicode len 1 unicode name SPACE --break-- key 13 unicode len 1 unicode name no name --break-- key 273 unicode len 0 unicode name Traceback (most recent call last): File C:/tmp/unicode.py, line 11, in module print 'unicode name', unicodedata.name(e.unicode, 'no name') TypeError: need a single Unicode character as parameter ##end program output## A Ubuntu 8 Compaq desktop, Python 2.5.2, Pygame 1.7.1, produces the same results.

Re: [pygame] antialiased circles
gfxdraw is from pygame2, I assume? Thanks Rene, I'll give it a try. Pygame2 looks quite awesome. Is the 1.9 branch gonna keep being maintained when pygame2 is official? it breaks backwards compatibility, I guess, are you just going to keep it with a different name so they can be installed together?

They already use different names, (pygame -- package pygame, pygame2 -- package pygame2), so they can be installed at the same time without influencing each other.

No need to use pygame2 for gfxdraw, it's in pygame. yeah, pygame is still going. But might be renamed to pygame10... or pygame12 ;)
Re: [pygame] Code review for Pygame2 example
Hi, I tried your example and it doesn't work. Python exits abnormally and Windows 7 pops up with a message saying would you like to end the program Python or whatever. No traceback. Any ideas?

In retrospect, I should have created lots of independent examples, each demonstrating one function of Pygame2, but I chose instead to show them all at once. Here's the resulting example: http://pygame2examples.googlecode.com/files/pygame2alien.tar.gz. It's based on the oldalien.py example from the original Pygame, but I tried to abstract the graphics from the rest of the game. The result is a quagmire of poorly-applied design patterns; nevertheless, it runs and shows off several features of Pygame2.
