Pygbag newbie here. Here's a main() that establishes socket connection to a server at localhost, port=2222. |

you need a websocket proxy in front of the echo service for the browser to connect to. Browsers are not allowed to connect plain desktop sockets. |

Hi Paul, I now have my code using websockets . However, I’m using a python virtual environment and I think this is causing a problem… When I open a webrowser localhost:8000#debug I get this… (See line with <<<<< *****) ['noodling', 'sys', 'asyncio', 'websockets', 'pygame'] Traceback (most recent call last): Any idea? Thanks, |

you don't need to use websockets in python, the emscripten "os" layer is already converting browser websocket to normal socket internally for python. here's an example connecting to irc ( with websockify as proxy ) https://github.com/pygame-web/showroom/blob/main/pygame-scripts/aio.sockets.html |

Sorry, I don't understand what to do with 'example connecting to irc...'. |

@tom-denesyk if you really don't know what to do i suggest you join pygame discord. Also i won't provide any support for asyncio socket/streams from stdlib because asyncio is not suitable for game loops, uasyncio maybe but only if i have time for that and if pyscript does not take on that before (and they should). The aio.sockets.html page ( read its python source ) is exactly connecting a python wasm client to a python server ( in that case it is https://github.com/pmp-p/uircd + websockify ) |

I was very happy to find pygbag, although I think I might need to do a lot of refactoring of my PyGame code. Getting rid of yaml, numpy, etc. imports is doable. But I have a main game loop with functions that are occasionally called, which run in their own nested game loops. These self-contained loops, which correspond to different rooms, run several steps until the loop is exited, at which point they pop back up to the main game loop level. Is there a way to insert async-and-await code across my game files which contain these nested game loop functions and still get pygbag to work? Or will I need to extract the logic in these nested game loop functions and put it all on the top game loop level (no nested loops) to get pygbag to work? Thanks! |

I had a feeling that was the case. :( Thanks for the quick reply and the reference! I'm gonna make it work! |

btw numpy is ok for 3.11 |

cool, I will try it in 3.11 and see if importing numpy doesn't error out. That would save me refactoring a good bit of code. |

Second question, while I'm here :) ... memory management... Are there optimization techniques I should use to avoid the memory error I get when I load a lot of pngs at the start of my game? Perhaps if I load this data right before I need it, and then clear it from memory afterwards using something like "with open()", I will be ok? |

To avoid eating memory use a 1024x600 screen resolution and resize your sprites accordingly. If you have too much sprites i don't know maybe use a cache but i'm not sure how and when sprites memory will be released ( if it is ). That would need testing . |

ok, I'll experiment. Thanks again! |

Update: I was able to refactor my PyGame code and incorporate pygbag. Thanks again for creating this pivotal library! "Digital Physics" the video game will be released on itch.io on Groundhog Day, February 2, and thanks to pygbag, people will be able to play it in the browser! I'll post the link when it is released. Thanks again! |

Ok, here's my "Digital Physics" game built with pygbag 0.5, python 3.10.8, pygame 2.1.2. I'm really happy with the deployment results, so thanks again! I look forward to seeing how future versions of the pygbag library evolve. https://digital-physics.itch.io/digital-physics Feel free to try the game out, offer feedback, and share it with people. Thanks again! |
