10 classic games

[lordmauve]

The Raspberry Pi foundation would like a collection of 10 example games written with Pygame Zero to form the basis of course material. These games need to be licensed for possible commercial use by the Raspberry Pi foundation as well as CC-BY-SA, under which they will be included in the Pygame Zero distribution.

The games need to be written as clearly as possible, with plenty of docstrings and comments, so that the way they work is obvious. However any working implementations of games would be gratefully received, and can be improved afterwards.

Below is a suggested list of games that could be created as example games, as well as the contributors who have made an offer to complete these games. This list is not exhaustive, but large, open-ended game projects are much less suitable than simple reimplementations of classic games.

• Snake - @lordmauve Merged
• Pong - @IvanMesic Merged
• Breakout - @tjg
• Space Invaders - @jrmhaig
• Flappy Bird
• Asteroids - @Avaren Merged
• Joust
• Lunar Lander - @timboe Merged
• Defender
• Minesweeper - @MiniGirlGeek Merged
• Robotron
• Tetris - @drobban
• Memory/Tile game - @holdenweb Merged

I can contribute the version of breakout I've been using to teach at my Club. It'll need some brushing up, but most of it's already there. The original version was done by our team at the Dojo, but I've more or less rewritten it all since then.

Would like to start working on Pong. Let me know if you are interested.

@drobban, I already started working on Pong game.

Well, is tetris taken? If not, I would like to work on it.

@drobban - Great! I've put you down for that. Be aware that Tetris clones have been the subject of copyright suits:

I suspect we'd be Ok if we just make it look a bit different and avoid calling it Tetris.

I'd love to have a go at making minesweeper if that's OK?

I came here to say I was having a bit of a look at Lunar Lander and had some questions but have just been tweeted by Nathan to say he hasn't started on Space Invaders yet so I may have a go with that instead.

Regarding Lunar Lander, it requires the ability to rotate an actor but there doesn't appear to be that feature implemented, or I have looked in the wrong place. Has anyone given any thought yet about the best way to do this?

Edit; And I've just looked at the pull requests and the one for issue #3 is about rotation and the comment about anchors is exactly the problem I encountered from my experiments.

Hey,
Having had a quiet Sunday, I've also had a play around with a basic Lunar Lander.
Will post when it's a bit more polished

Well, here is a start at Space Invaders. Nothing too earth shattering yet - more of a declaration of intent (and making it available for pull requests).

Nice work all. I'm going to check all these out as soon as I get a chance.

Hi, pushed to https://github.com/timboe/pi_lander
As mentioned above, no rotation yet in pygame so have included some entry-level trig in degrees and rendered exclusively with draw commands, but this works well for vector-style.
Cheers,
Tim.

Found some time to get started.
Not near finished yet.
Look at it just as an progress report: https://bitbucket.org/drobban/tetra_puzzle/commits/branch/master

Still quite a few things to do but it is in a playable state:

https://github.com/jrmhaig/rpi_projects/tree/master/SpaceInvaders

Now it is at a point where it can actually be played I will probably not be adding to it so frequently. Pull requests are welcome. It needs barriers, mystery ships, better levels (rather than just speeding up), high scores, ... :-)

Minesweeper is now playable and has a setup screen, it should be completely finished soon :)

https://github.com/MiniGirlGeek/PyGame-Zero

run pgzrun setup_screen.py to play

I've merged some of these implementations into the repo just so they can be in for the 1.1 release, which I've just cut. These were

• @MiniGirlGeek - this is great! I didn't want to include the menu and subprocess stuff, so I just dropped that and took the basic implementation
• @timboe - merged with only a small deprecation fix
• @holdenweb - merged, but I replaced your face with a playing card image I hastily drew

I did this in the most clumsy and hasty way possible, by snapshotting the Github repos. I linked to the original Github repos in the commit messages, but I forgot to ensure there were README files so that people can track the upstream development. I will try to do this for 1.1.1!

I haven't looked through all the other games yet. I wanted to get a release done today so I can get the results of the Europython sprint out to users, so I took a few things I could grab quickly.

I've added win and lose messages, and the grid reveals all mines when you lose and tells you if you mis-flagged a mine

I believe that I have something that could be used as an example game.

@lordmauve - https://bitbucket.org/drobban/tetra_puzzle
Perhaps you want to take look before I try to push it to the project.

Made a pull-request for my contribution.

@lordmauve I'll pick up robotron 👍

[tartley]

Wireframe mag has an implementation of Phoenix that is creative commons, that can probably be used: https://github.com/Wireframe-Magazine/Wireframe-26

[lordmauve]

Thanks @tartley. I think Raspberry Pi have whatever they need now. They've been producing Wireframe for a year with Pygame Zero code samples in each; also Eben's book has gone to print. I think we can close this.
