commandline on mac os x

zaanan

Hello, I am trying to start doom.wad using the following command in an applescript:

do shell script "/Applications/Games/Doomsday/Doomsday\\ Engine.app/Contents/MacOS/Doomsday\\ Engine -game jdoom -iwad /Applications/Games/Doomsday/wads/doom.wad"

All it does is open SnowBerry. What am I doing wrong?

1.9.0-beta5.1-universal-macosx on 10.5.8

BTW, the game runs beautifully! And SnowBerry is really nice, just want to run the game directly. Thanks in advance!

KuriKai

point to the deng binary inside the .app?

Hi KuriKai,

Do you refer to Doomsday.app? I have tried this:

do shell script "/Applications/Games/Doomsday/Doomsday\\ Engine.app/Contents/Doomsday.app/Contents/MacOS/Doomsday -game jdoom -iwad /Applications/Games/Doomsday/wads/doom.wad"

And I get this error:

DD_InitDGL: Loading of drOpenGL.bundle failed.
(null).

Any ideas? Thanks.

Some pointers:

• Doomsday expects a specific working directory upon launching. If it says the loading of a bundle has failed it means that the working directory was not correct and the plugin bundles could not be found.
• To see the command line used by Snowberry, select the profile to launch and press Option-P. (Or select "Preview command line" from the menu.)
• The -basedir option is important as well as it controls the location where Doomsday loads its resources (doomsday.pk3 in particular).

Here's an example command line that should work (when executed in /Applications/Doomsday Engine.app/Contents):

Doomsday.app/Contents/MacOS/Doomsday -game jDoom.bundle -iwad ~/IWADs/Doom.wad -file Doomsday.app/Contents/Resources/doomsday.pk3 jDoom.bundle/Contents/Resources/jDoom.pk3 -bd Doomsday.app/Contents/Resources/

(Naturally substitute the IWAD path with one that suits your setup.)

Thanks for the help skyjake. I can now run a specific wad from the command line. However, there are a few concerns - it creates a "savegame" directory in the working directory (Contents) instead of saving games in my runtime/savegame directory. And I had to reconfigure the graphics, mouse, etc. from scratch, so I am afraid it is saving those settings in an inappropriate place as well. I have tried adding the -savegame switch with variable path sdir:

set sdir to "$HOME/Library/Application Support/Doomsday Engine/runtime/savegame/doom1-ultimate"
... -basedir Doomsday.app/Contents/Resources/ -savedir \"" & sdir & "\" -sfxchan 16 ...

That just creates an Application directory at the same level as my ~/Library/Application Support directory, which tells me it's the spaces. But when I try

set sdir to "$HOME/Library/Application\\ Support/Doomsday\\ Engine/runtime/savegame/doom1-ultimate"

it does the same thing. Adding quoted forms, posix paths, etc. only make it save the game in Contents again, or not at all. Please advise.

I hate to keep asking questions on this board, but there is a complete dearth of Mac commandline instructions for the Doomsday engine. Thanks for your time.

Well, Doomsday was never intended to be started directly from the command line -- it has always been accompanied by a GUI launcher. Thus the command line options and the way it handles working directories are a bit complex.

You should use the -userdir option to define where the engine will save your config files, savegames, etc. For example:

-userdir \"/Users/jaakko/Library/Application Support/Doomsday Engine/runtime\"

Here's a shell script that can be run from anywhere. This is equivalent to what Snowberry does when it launches the game (modify to suit your system):

#!/bin/sh

pushd .
cd "/Applications/Doomsday Engine.app/Contents/MacOS"
"../Doomsday.app/Contents/MacOS/Doomsday" \
    -appdir ".." \
    -file }doomsday.pk3 \
    -basedir \"/Applications/Doomsday Engine.app/Contents/Doomsday.app/Contents/Resources\" \
    -userdir \"/Users/jaakko/Library/Application Support/Doomsday Engine/runtime\" \
    -file }../../../jDoom.bundle/Contents/Resources/jdoom.pk3 \
    -notexcomp \
    -wh 1024 768 \
    -wnd \
    -game jDoom.bundle \
    -iwad \"/Users/jaakko/IWADs/Doom.wad\"

popd

Hey, sorry - got quite busy with other things for a bit - tried your script and it works great, so thanks skyjake! I must say, OS X aliases suck when compared to linux or Windows app shortcuts - not being able to simply add commandline switches was a major shocker for me.

Any plans to build more commandline support into future versions? A simple switch method like "doomsday -plutonia" (like scummvm uses, for example) that could go into an applescript (instead of a shell script) would be awesome. Is there a way to sponsor a feature like this? I would be happy to donate, especially after your excellent help for this free app.

Thanks again!
