ECWolf - Wolfenstein 3D source port for mods

tpo1990

@ExarKunIv Maybe you have downloaded @cyperghost scriptmodule before the patch was added.

Uninstall and if it still compiles without the patch, then go to /home/pi/RetroPie-Setup/scriptmodules/ports/ and delete the ecwolf.sh file, then download @cyperghost scriptmodule again and reinstall.

@cyperghost @tpo1990 ok i see whats going on. when i ran the wget that cyperghost just posted it worked fine but it put the new ecwolf in the /home/pi dir not the setup script folders

so when i ran the .sh again it was the old version.

i did not know that i needed to manual copy it in the the setup folder, which for me is no big deal

but thanks for letting that it was just on my end. :)

@cyperghost ok that worked, i did see the patch was applied but i did get a error about the shareware games or something

just letting you know.

@ExarKunIv Well I really can't help you. The demo version are downloaded through an downloadAndExtract script introduced by helpers.sh
For me this works fine and it did so in my tests, it's the exact same command as @tpo1990 used in his 1st version of the script.

I guess it's a corrupt download of the demo files, try to obtain the files by manual and check if you can unzip them.
Or can you give the output if you use file wolf3d14.zip and file soddemo.zip

cyperghost

@tpo1990 I'm on long vacation now so I can't login to git now. But you've said there is a problem in downloading source file.

It's still available, you can get the ecwolf-ecwolf-5065aaefe055.zip by using this link and it's the same link still in the scriptmodule .... I would stick to one version as long as possible if there is no reason to change. Every history commit can be downloaded as long as the resporitory is available.
Did you receive an error message?

http://maniacsvault.net/ecwolf/files/ecwolf/1.x/

These versions are all outdated, March 2019 is the newest one

You can still obtain a proper url from newest zip or tar file by "test-extracting" the archive and then read out root path. But as I said I'm on vacation now and I can't directly test on the RPi. But as far as I see the scriptmodule works ... You can of course fork on your github and use the gitpull command then you've control of the version.

EDIT: I rather think I've removed one dependencie by accident and therefore the compiling will not work on your mashine if you build this up on a fresh install. This usecase I've never tried out to admit.

ExarKunIv

@cyperghost yeah not sure either.

i uninstalled it and deleted the wolf3d folder and reinstalled it, this time it worked just fine. not sure what that was all about.

tpo1990

@cyperghost Enjoy your vacation. I will try again with the link you gave me and see if i can sort it out in the scriptmodule that will soon get uploaded to my git repo.

I agree in that there is no reason to change the version as long as it works. I will look into which dependencie that was removed.

cyperghost

@tpo1990 Yes I'll enjoy my vacation for sure ;) Thank you.

About errors... they are stored to $HOME/RetroPie-Setups/logs from there use an log viewer or gunzip the file you're interested then you'll see if there is any. Maybe you can create a new patch for upcoming versions, you've hast to add the btn_esc and the btn_pause - line to the source code but as I said I saw no massive development in the newest code but it's up to you.
I'm looking forward into your PR for RetroPie

@ExarKunIv Yes seems like a broken download that makes the demos not being extractable. I think I will later write a menu tool, that automatically rescans for new added games, in the some logic as the installer does and maybe a "export" feature to make games directly accessable to ports section. If you want to add new games you've to check the files in ports/wolf3d and copy or change the Wolfenstein 3D (demo).ecwolf. Change the WL1 to WL6 or wl6 according the correct file extension of the full version. The .ecwolf files are called through Wolfenstein 3D*.sh files in ports section ... I think you will understand if you see the files. As I said I think I'll write a small tool that will do by automatic.

tpo1990

@cyperghost Good. I know of the logs folder. It is really great for finding out which part of the functions in the scriptmodule that does not work and also what the error says.

I just tried again and this time i got the scriptmodule working with the same url for the nightly build we originally used and it works great along with your patch. I'm thinking that it was just some small typo in the code with downloading the nightly build.

I also tried adding the Astrostein mod again with copying the existing wolf3d .ecwolf file and changing it into loading the astrostein .pk3 file along with a Astrostein.sh runcommand file. This is triggered by the --file command.

The mod works. I think this approach works good and i really think that most of the RetroPie users will be able to get it to work with other mods as well by following a how-to guide and if so, you could come up later with a selection menu that will add recognized mods or games to it, but for now this seems sufficient enough.

I will make the changes and update the scriptmodule very soon. I just need some more testing before making it into a PR.

cyperghost

@tpo1990 Just a suggestion for the demo files, I would put them into a dedicated directory named shareware or freeware therefore

function game_data_ecwolf() {
    if [[ -z $(ls "$romdir/ports/wolf3d") ]]; then
        mkRomDir "ports/wolf3d/shareware"
        cd "$__tmpdir"
        # Get shareware game data of Wolfenstein 3D and Spear of Destiny
        downloadAndExtract "http://maniacsvault.net/ecwolf/files/shareware/wolf3d14.zip" "$romdir/ports/wolf3d/shareware"
        downloadAndExtract "http://maniacsvault.net/ecwolf/files/shareware/soddemo.zip" "$romdir/ports/wolf3d/shareware"
    fi
}

Because the full version is always named wolf3d14 and then we have possibly a mix in one folder with only a difference in file exetension. All in all it really does not matter but I think it's much clearer so and people see instantly what versions they have installed.
In some kind we have to outbeat WOLF4SDL ;) - easy setup and tons of addons!
btw.: I was never able to get WOLF4SDL run the full version ...

tpo1990

@cyperghost That is a good idea in reducing the shareware(demo) versions to it's own subfolder in order to make any less confusing parts about the data files location.

For the sake of ECWolf i think it's biggest advantage is the capability to run mods, making the more superior Wolfenstein 3D source port. We can only do so much, since in the end it is up to Jools Wills and the folks behind RetroPie to accept the PR once it has been created.

Funny, i also never got Wolf4SDL to run the full version either even though i was trying to follow the official guide from the RetroPie wiki. ;-)

I will make the change for the shareware(demo) versions straight away in the scriptmodule and then test it out before uploading to my git repo. :-)

tpo1990

Big news. The ECWolf scriptmodule has been updated with a major revision to the code making it easier to locate the game data files of both shareware and registered versions of Wolfenstein 3D and Spear of Destiny episodes.

A keyboard escape fix patch has been added to make it much more easier to map your controller to the escape key for exiting the game. Mods can now be added in a much more structured way thanks to @cyperghost work. (You can find the mod instructions on the first post in the topic).

Run the Download again and update your ECWolf installation or uninstall first, then download and reinstall again.

The scriptmodule is not for testing anymore and is now recognized as a stable release. It might just see a PR soon for the RetroPie project. :-)

cyperghost

@tpo1990 It would be nice if you would include the patch also in your repro ;)
Why? If I delete my branch then the file is lost.

Please don't copy and paste the text, rather download the file and upload it again.
Why? With copy and paste you will likely lose line endings and then the patch will not work.

Therefore are PR are state of the art in software development ;) They are a history lookback in the code source.

Look at your code idents, in the codeblock

function sources_ecwolf() {
    downloadAndExtract "https://bitbucket.org/ecwolf/ecwolf/get/5065aaefe055.zip"
    mv ecwolf-ecwolf-5065aaefe055 ecwolf
}

you've setted 8 spaces instead of 4 ;)

Keep up the good work. Thank you for this jewel
Best wishes

cyperghost

@tpo1990
Thanks for merging ;) ... one little last thing....

wget -N -q https://raw.githubusercontent.com/tpo1990/ECWolf-RPI/master/ecwolf_keyboardpatch.diff

I removed the --show-progress switch (just for cosmetics) and more important... the download points to your repro. So you've 100% control of your future PRs

About the patch, I'm not sure if there is a better way to use the patch inside the scriptmodules but I recieved no answer as I asked for this :(

Next stop: Retrogaming of Wolfenstein 2D ;)

tpo1990

@cyperghost No problem. It has now been corrected in latest git.

Thanks to you the scriptmodule is much more refined. I noticed it also. Maybe we will receive a answer for a better way of applying the patch, otherwise it will still work fine as it is. Perhaps, when after creating the PR for RetroPie project someone could come up with a better way.

Now that is a title i have never tried out. I might as well try it out some time. :-)

Happy retrogaming ;-)

cyperghost

@tpo1990 I think we can use applyPatch
Instead of the patch -i -p0 command just use applyPatch
I think this could work...

apply Patch uses -f -p1 command

Difference between p1 und p0 is
- p0: ./src/wl_play.cpp
- p1: src/wl_play.cpp

So this may work out of the box! Maybe @mitu can say more to this - patchfile is here -- thank you.
The -i switch isn't needed here because helpers.sh redirects file output to patch command with patch -f -p1 <"$patch"

The reason for using the helpers functions is, that they give feedback to the processing with error codes. You can try out if this works and then I'm really out of my knowledge. I think that patches then are stored to RetroPie-Setup.

tpo1990

@cyperghost According to helpers.sh file, the function applyPatch is used for applying patches against upstream code and will apply a patch if it has not already been applied to the current folder.

This sounds like it could actually work, so meaning.

applyPatch -f -p1 ecwolf_keyboardpatch.diff

Let me try it out and get back to you.

cyperghost

@tpo1990 No... use only

applyPatch ecwolf_keyboardpatch.diff

please

The applyPatch function accepts just one argument - the patchfile itself

See here

tpo1990

@cyperghost I see. I am trying again.

Until now at this point it did apply the patch with the applyPatch so far so good.

Edit: Just tested it in game. It works. I can see the escape game key function in options.

cyperghost

@tpo1990 There should be now a (empty) file named ecwolf_keyboardpatch.diff.applied be inside the build folder.
(So the helpers function says)
You know $HOME/RetroPie-Setup/tmp/build/ecwolf/ecwolf (??)

Edit: Just tested it in game. It works. I can see the escape game key function in options.

Perfect! But if you see the messsage of a patched file you can break the process. It will work as usual. But consider this is testing ;)
