Doomsday Engine

Still relevant?

Yep! Nothing's changed since then.

I'm suspecting this is a (Python) version conflict.

- Which Mac OS X version are you running?
- If you open a Terminal and type "python --version", what is printed?

I'm running Mac OS 10.4.11

"python -v" shows version 2.3 I think:

I have 10.4.11 on my PowerBook G4 with the same Python version and there it runs fine, so it must be something else...

A few more things to try:

- Rename your "Doomsday Engine" folder under "~/Library/Application Support" to "Doomsday Engine old". Maybe there's something wrong in there that's causing the issue.

- Try starting Doomsday Engine.app directly from the distribution disk image (not from your hard drive).

Well renaming the folder to "Doomsday Engine old" got me to a new point. Starting the engine from the disk image produces the same results.

First, I get this error from Doomsday Engine:

Error
Plugin Error
The loading of a plugin failed, while executing tab40_settings.init().
Reason:

File "sb/widget/list.pyo", line 741, in __updateItemCount
File "wx/_windows.pyo", line 2054, in SetItemCount

Then after clicking OK and waiting a long time I get this, 3 times in a row:

Error
Runtime Error

Exception:

Then the setup seems to proceed as normal, asking languages, which games I want to setup and telling me to locate my WAD file.

It freezes after I try to create a new profile, then works forever, then gives two more runtime errors. Repeat every time I try too set up a new profile.

The folders within the Doomsday Engine folder in Application Support are all empty except for "profiles."

I already reinstalled Python and Doomsday Engine.

Oh, when I renamed the folder to "Doomsday Engine old," a new folder, "Doomsday Engine" was created. I deleted Doomsday Engine old, and am now referring to the new Doomsday Engine folder for these reports.

This is looking awfully lot like a bug in wxPython, or some glitch particular to your system due to the fact that the version of wxPython distributed with Doomsday Engine.app is intended for Python 2.5.

What happens if you upgrade to Python 2.5? You can get the .dmg here: http://www.python.org/download/releases/2.5.4/

I installed Python 2.5 from that link and I get the exact same errors.

Am I missing some step in installing Python 2.5? Do I need to delete my other Python versions?

I'm out of ideas... As far as I can tell it appears to be some glitch specific to your system that wxPython doesn't like.

This could be verified by downloading wxPython from www.wxpython.org: the Mac OS X runtime for Python 2.5 (osx-unicode) and the osx-demos-docs packages. If the official wxPython demos fail to work then it's definitely a wxWidgets issue.

Just installed Python 2.5 again, and wxPython 2.5. I ran the wxPython app, and it seemed to work. A nice GUI screen came up. Same symptoms in Doomsday Engine though!

I guess don't worry about it, I found PrBoom and that works fine. I'll try Doomsday on my girlfriend's new Mac, and I'll report back here if anything doesn't work.

Thanks for helping out!
