WASM: RuntimeError: pygame.PixelArray is not available

[coppermouse]

Versions:

• pygame-ce 2.1.4.dev1 (SDL 2.24.2, Python 3.11.2)

Background:
I am using https://github.com/pygame-web/pygbag to run a game in browser.

I got a RuntimeError: pygame.PixelArray is not available error when I try to call PixelArray().

I open a discussion on pygbag making a suggestion to make PixelArray available. I thought this was closer to pygbag than pygame-ce.

After some discussion I was told the issue was on pygame-ce / pygame wasm port

pygame-web/pygbag#103 (reply in thread)

Issue:

pygame.PixelArray does not seem to be available when in wasm port.

To replicate error message try run these two commands in the "wasm-port." ( I run them through pygbag session )

import pygame
pygame.PixelArray(pygame.Surface((1,1)))

I was given this link to test: https://pygame-web.github.io/showroom/python.html?-i
(but I think it might use based on pygame (not pygame-ce))

I of course have tested this locally with pygbag and looking at the output it seems to be using
pygame-ce 2.1.4.dev1 (SDL 2.24.2, Python 3.11.2)

Even though the pygbag-version is most likely not relevant because it out of your scope I still inform you that I use pygbag==0.7.1

I responded in the linked pygbag issue. If you've only tried import pygame.PixelArray, it's going to give an error, even locally. That's not the correct import. Try import pygame.pixelarray

On this version:

• pygame-ce 2.1.4.dev1 (SDL 2.24.2, Python 3.11.2)
  (not sure what WASM port version)

and with this code:

print("===========")
print("import pygame...")
import pygame
print("...done")
print("import pygame.pixelarray...")
import pygame.pixelarray
print("...done")

I get this output:

===========
import pygame...
...done
import pygame.pixelarray...
181: FIXME dependency table for manually built modules
1202: want='pygame.pixelarray' found : False
PKG NOT FOUND : want='pygame.pixelarray', resume=<function <module> at 0xf1b920>, ex=ModuleNotFoundError("No module named 'pygame.pixelarray'")

just to be clear, this is in a browser through pygbag

Why are you using a dev version of pygame-ce? Try using the most recent version (2.3.0)

I am using pygbag 0.7.1 :)

I do not think I am in control what version of pygame-ce it is using

@pmp-p I don't think this is a pygame-ce problem. Pygbag is using an out-of-date dev version compiled from source. printing pygame.__dict__ in pygbag reveals that pixelarray was not compiled into the version being used

[coppermouse]

Maybe. I do not know :)

I was told it was a bug in wasm pygame port and it should be reported here.

Thanks for the hint, i'll try on a fresh build as soon as i have some time

By reading the comments I have to trust that the issue is not in pygame-ce and therefore I close this issue.

[pmp-p]

2.3.1.dev1 does not seem to have a working pygame.PixelArray, so I would not close until pinpointed

edit/ seems that pygame.pixelarray is not in inittab ( or in multiphase init i don't know yet).

[pmp-p]

found the problem.

Question : is this module usefull or not whitout numpy ?
