Bone Rush - pyglet resource error

gummbum on 2018/10/31 03:11

Hello. Project https://pyweek.org/e/ThEdA_P22/

I started out getting errors with pyglet's resource module not allowing backslashes in its path elements. I surmise it's a peculiarity of Python on Windows. This was easily worked around by replacing in main.py and run_game.py all of the os.path.join() with "/".join().

But I hit an error I can't solve. Help would be appreciated. :)

I hope you are using the pyglet version 1.3.2

the latest version 1.4.* seems to have compatibility issues with cocos library.

gizmo_thunder on 2018/10/31 13:42:

Also it seems strange to me that you had to replace the os.path.join() with "/".join() not sure if its' a windows thing though.

gizmo_thunder on 2018/10/31 15:14:

Ok, turns out pyglet doesn't want to deal with the "\" which is what os.path.join() would throw on windows..

@ gummbum thank you for reporting and taking the effort to fix the problem. Please follow the below steps to get it work

replace line 199 in ccbreader.py to look like following:

font_name=lbl.FontName().decode('utf-8')[:20],

the pyglet resource thing is a known issue on windows.... last pyweek I patched a pyglet version but forgot to submit it as a pull request or bug report. Maybe this time I will.

gizmo_thunder on 2018/11/08 04:11:

Please please .. submit it. I didn't realise this was an issue. I've tried to get the big re-opened. Posted the sample code which produces the error.

Haven't heard any response back though.

Hi again I dig into my older pyweek files and I found the patched file. Its resource.py and I have pasted the patched file here: https://bpaste.net/show/720420eb5a91 Look for the two additional

        name = os.path.normpath(name)

call that I added at lines 418 and 434.

This should do the trick I think.

gummbum on 2018/11/10 06:11:

Apparently I needed both fixes, the ccreader.py mod and the pyglet mods. Thanks, guys. It runs now.

gizmo_thunder on 2018/11/10 11:11:

Yup.. one is a bug in pyglet the other in cocos for windows specifically.
