It's happy dance time.

pygame 2 is out.

It looks like we're 20 years old.





ps. we have a present for you coming shortly.

Saturday April 18th to Tuesday April 21st, 2020
Starts at 3:00 AM CEST *

Join us for Ludum Dare 46, our first event of 2020!

For the next two months, I'd like to try to focus on pygame 2 critical issues.

Backwards compatibility issues people are reporting with the pygame 2 dev releases.

So there's a feature freeze on anything not related to these issues. One issue at a time until the two months are up or we are done.

 

The first issue is: "SDL 2: Per Pixel Alpha error".

Over the next weeks we have plenty of game jams that people from the pygame communities take part in.

Alakajam is first starting on September 20th. "Alakajam! is a young community gathering game development enthusiasts from all backgrounds. We host a series of informal events, that give you a chance to both make games and get people to play them. Alakajam! competitions, taking place over a week-end, three times a year. Start/end times are suited to European timezones."

Then the must-use-python PyWeek challenge "Invites entrants to write a game in one week from scratch either as an individual or in a team. Is intended to be challenging and fun. Will hopefully increase the public body of python game tools, code and expertise. Will let a lot of people actually finish a game, and may inspire new projects (with ready made teams!)." PyWeek runs from Sept. 22, 2019 to Sept. 29, 2019, and theme voting is already on.

Finally, Ludum Dare is an event where you create a game from scratch in a weekend based on a theme. Saturday October 5th to Tuesday October 8th, 2019. Starts at 12:00 AM CEST *. Ludumdare is the oldest online game jam, and has the largest number of participants. There is a Jam (72h, less restrictive rules), and a compo (48h more rules). The Jam now lets people submit paper board games, and even things like crafts that aren't games at all!

Want to join in as part of a team? The pygame community game (stuntcat) is also taking part, by creating a new mini game for some of these game jams. Drop into the discord chat #communitygame channel and say hi ( https://discord.gg/r8yreB6.

Also, how about inviting women and non-binary people to make the game with you?

If you want to join in online, come into our 'Discord' #contributing channel https://discord.gg/r8yreB6. If you're at EuroPython you can find information about the sprints on their website.

Whilst we focus like a shark-lazer on pygame 2, here is a bonus pygame 1.9.6 with a couple of small regression bug fixes.

- mp3 via smpeg was missing in manylinux builds.
- mixer thread deadlock issue when controlling it from different threads.
- pygame.version.vernum now has major, minor, and patch attributes.

TLDR; Some highlights.

Every single source file has been heavily modified and moved in this release. Initial (source code only) support for SDL2 has been merged in. We also support compiling with SDL1 in the same code base, so the migration to pygame 2 is easier. pygame 2 will be released with SDL2 being the default backend when some remaining issues are ironed out. The 1.9.x releases will continue with SDL1 until then. Also, the C API of pygame is undergoing a transformation with lots of cleanups. Then there have been plenty of other cleanups all throughout the python code as well. There's still lots to clean up, but things should be significantly easier for people to contribute (👋 hello and thanks new contributors!). The documentation has been improved with better examples links, search functionality, and improved navigation. Support for older Macs, and newer Macs has been improved. The mask, midi, draw, and math modules have gotten lots of polish with rough edges removed.

Thanks

A very special thanks to the people who have volunteered commits to pygame since the last release. In alphabetical order...

Quite a few new people have helped out with this release 🤗

An equally special thanks to everyone else who has contributed in other ways. Thanks to claudeb, imallet, and deshipu for moderating the discord chat to keep it friendly. Thanks to the twitter folk, and the stackoverflow Q&A people. Thanks to everyone who puts their game up on the pygame website for others to look at. Thanks to people making tutorials and sharing articles & books they've written. Thanks to the r/pygame mods and community. Thanks to pyladies groups for running fun sessions, and for making things better. Thanks to the teachers providing feedback, and for doing something fun with their students. Thanks to Debian, Raspberrypi, Arch, Fedora, and all the other community groups. 🖤

🐱‍🏍 stuntcat is our open source mini-game we worked on in order to drive pygame 2 development forward. We wanted to make a real mini-game and try to release it for sale on as many platforms as possible. So that other people can look at the source code and distribute their game on more platforms too.

We only had 4 days... but during that time more than 14 people got involved. We learnt a lot during this. The compilation instructions for pygame 2 were improved so that more people could build development versions. We automated the installer generation for Windows, Mac, and pypi on github (so other projects can copy this base-code and do it too). Gif animation saving was started (because when you release your game you want a gif right?). Missing features and areas where documentation could be improved were identified (animated sprites, and scenes anyone?). Fixes to pymunk (a great 2D physics engine) were made so distributing physics games to end users is now easier. There's also an example of using the tile map loader (PyTMX) with the physics engine. More than a month after the game jam finished we are working on issues discovered during the making of 🐱‍🏍 stuntcat.

We want to make distributing pygame apps easier for people. You made your game, now you want to share it with your friends or even sell it right? The first place we made a release was on itch.io, a platform for selling games and apps. There we uploaded the Mac, Windows, and source for people to download with a pay-what-you-feel option.

Next step is to release the game on Steam (another popular games platform). For the next step we need to raise $100 for the Steam App fee. We also have to make the game better! It's already a pretty fun mini game, but requires more mini games and more polish. We also need to make pygame 2 pre-release binaries so that we can actually publish on Steam.

Thanks to the makers of stuntcat: bitcraft, blubberquark, Bottersnake, claudeb, illume, Kuba | ThePolish, TJWhale, hfoxp, xeno, M, CaptHurls, dlon, dirk0, viblo, and kleines filmröllchen.

---

day 0: $0 of $100 raised for Steam app fee.
day 1: $5 of $100
day 2: $57 of $100
day 3: $100 of $113.20
day 14: $107 of $113.20
day 20: $127 of $113.20
If you ever wanted to support pygame development financially and you can afford it, this is how you can by purchasing stuntcat on itch.io for $2 or what ever you feel. update: we raised enough to make a steam release. Thanks to everyone who chipped in!
