PyGame wasm for everyone ( packager + test server )
"your_game_folder" must contains a main.py and its loop must be async aware eg :
import asyncio
import pygame
pygame.init()
pygame.display.set_mode((320, 240))
pygame.display.set_caption("TEST")
async def main():
count = 3
while True:
print(f"""
Hello[{count}] from Pygame
""")
pygame.display.update()
await asyncio.sleep(0) # very important, and keep it 0
if not count:
pygame.quit()
return
count = count - 1
asyncio.run( main() )
# do not add anything from here
# asyncio.run is non block on pygame-wasm
usage:
pip3 install pygbag --user --upgrade
pygbag your_game_folder
command help:
pygbag --help your_game_foldereg
user@pp /data/git/pygbag $ python3.8 -m pygbag --help test
*pygbag 0.0.9*
Serving python files from [/data/git/pygbag/test/build/web]
with no security/performance in mind, i'm just a test tool : don't rely on me
usage: __main__.py [-h] [--bind ADDRESS] [--directory DIRECTORY] [--app_name APP_NAME] [--cache CACHE] [--package PACKAGE] [--version VERSION] [--build] [--archive] [--main MAIN] [--icon ICON] [--cdn CDN]
[--template TEMPLATE] [--ssl SSL] [--port [PORT]]
optional arguments:
-h, --help show this help message and exit
--bind ADDRESS Specify alternate bind address [default: localhost]
--directory DIRECTORY
Specify alternative directory [default:/data/git/pygbag/test/build/web]
--app_name APP_NAME Specify user facing name of application[default:test]
--cache CACHE md5 based url cache directory
--package PACKAGE package name, better make it unique
--version VERSION package name, please make it unique
--build build only, do not run test server
--archive make build/web.zip archive for itch.io
--main MAIN Specify main script[default:main.py]
--icon ICON package name, please make it unique
--cdn CDN web site to cache locally [default:https://pygame-web.github.io/pygbag/]
--template TEMPLATE index.html template
--ssl SSL enable ssl with server.pem and key.pem
--port [PORT] Specify alternate port [default: 8000]
Now navigate to http://localhost:8000 with a modern Browser.
v8 based browsers are preferred ( chromium/brave/chrome ... ) because they set baseline restrictions on WebAssembly loading. using them while testing ensure proper operation on all browsers.
NOTES:
-
first load will be slower, because setting up local cache from cdn to avoid useless network transfer for getting pygame and cpython prebuilts.
-
each time changing code/template you must restart
pygbag your_game_folderbut cache is not destroyed. -
if you want to reset prebuilts cache, remove the build/web-cache folder in your_game_folder
