ECWolf - Wolfenstein 3D source port for mods

cyperghost

@ExarKunIv Yes you have to edit Wolfensteins 3D emulator config file. It's located in /opt/retropie/configs/ports/wolf3d/emulators.cfg or in /opt/retropie/configs/ports/ecwolf/emulators.cfg and add a line

ecwolf = "pushd /home/pi/RetroPie/roms/ports/wolf3d; /opt/retropie/ports/ecwolf/ecwolf %ROM%; popd"
default = "ecwolf"

~~then you copy ecwolf.sh from github to /opt/retropie/ports/ecwolf and make it executable. I assume the binary of ecwolf is in same directory as the script file. Again! Make the script executable~~

then you copy Wolfenstein 3D.sh from github to /home/pi/RetroPie/roms/ports

That should do the trick so far....
File convention according this post

ExarKunIv

@cyperghost thank you, ill give it a go. not sure if i want a menu, or just have all the games listed in my ports.

right now im just getting my controls down good.

cyperghost

@ExarKunIv Well with the .ecwolf-method you can create a own system ;)
Of course you can set all parameters manually script files instead if you don't want a menu.

Everything is possible. If you don't want a menu you have to change the call from ecwolf.sh to ecwolf of course.

ExarKunIv

@cyperghost ok i got the files in and i was looking at the other post that you linked to.
i get what you said. the only thing that im lost on is that you have to setup up description files and you give the example of
Wolfenstein 3D - HighRes.ecwolf.
is that going to be a .sh file or something else

the rest you made it nice and clear

cyperghost

@ExarKunIv Well the .ecwolf format is setted up in two sections. Every thing over the wait command is considered as presetup, everything after wait is a postsetup

So Wolfenstein 3D.ecwolf with content

cd wolf3d_14
echo "Hello That Is Wolfenstein 3D`
sleep 5
ecwolf --data wl6
wait ?!
echo "This is the end"
sleep 5

Will do following

Changedir to wolf3d_14, base path is usually setted in your emulators.cfg (see pushd line)
Write Output (useless of course and just for fun)
Wait 5 Seconds (useless, too but I want to show how this works)
One command from ecwolf binary starting with double dashes, this commands just tells ecwolf to search for wl6 files to start Wolfenstein, wl1 would be the demo, sod is Spear of Destiny ...
Then the turning point ... the wait command ;)
again a message after ending the current game
a sleep command after ending the game

I hope I explained well. So all my .ecwolf files are in /home/pi/RetroPie/roms/ports/wolf3d, all vanilla wolf3d files (with Noah Arcs, Spear of Destiny and Wolf 3d itself) are in wolf3d_14 directory and then I've created a directory addons

ExarKunIv

@cyperghost oh i get it now.. i hope

.ecwolf is the file format

ok i think i get it enough for me to start playing around. if i come up with anymore dumb questions i will ask ;)

cyperghost

@ExarKunIv Yes .ecwolf is the file format for the graphical launcher and for the ecwolf.sh "translator" that relies next to the ecwolf binary.
You see all the commands are a bit differenct so I doubt that there will be a method to launch all pk3-modules with one file. Sometimes you load two pk3-files in one string (for music and highres graphics for example) so I think the .ecwolf-method is a nice compromise

ExarKunIv

@cyperghost works for me

cyperghost

@ExarKunIv Fine!
Remember with the dashes

You can also use this one

cd wolf3d_14
--data sod
--data wl6

This will result to load Wolfenstein 3D and not Spear of Destiny because last double dash command is used as cmd-line. We can deal with this so far.

@tpo1990 Are you still alive?

@cyperghost I've installed just now ECWolf on my home PC. I'm running Ubuntu 14.04 64-bits, plugged a Xbox360 controller through a wireless receiver, and opened ECWolf 1.3.3 (latest stable version, installed through DRDTeam's PPA).

It worked just like when I tested it on Windows a few weeks ago: I could access menus simply by pressing Start button, just like ESC key. And since RetroPie runs in Debian, which is where Ubuntu is based, then it's safe to say that it should work too.

I've done the same test in another controller too: a PS2 controller plugged through an USB adapter. However, to my surprise, Start didn't worked for accessing menus just like ESC key. In fact, neither of the buttons of my controller worked for going back to the menus.

The conclusion I could reach is: Start for accessing menus won't work for generic USB joysticks, but instead only for Xbox-like controllers. My guess is that the controller you've used is a generic one, and that's why you're having this problem.

Assuming my conclusion is right, you have three solutions for your problem:

Replace your generic USB controller for a Xbox-like one;
Use xboxdrv in order to emulate a Xbox360 controller from your generic USB joystick (you can use xboxdrv to map buttons to keys too, so you can simply map Start button to ESC key, as a workaround);
Edit ECWolf's source code manually, in order to implement a way of mapping start button to menus on your generic usb controller (some guys made it in ZDoom). Requires programming knowledge in C++.

Your conclusion is right.

I think if someone can step into the code and make some small changes to the code, that would be best.

cyperghost

@Solid-One @tpo1990
Okay done .... We can access main menu now. Assign a button key to ESCAPE GAME and you are fine

GOT TO POSTING 44

@BuZz Maybe interesting for you. ECwolf runs very good on Raspberry and outstands Wolf4SDL - I'm sure @tpo1990 can set a new PR now.

tpo1990

@cyperghost Hey sorry for not answering. I am still alive :-). I am on my on vacation and have had some house duties to complete.

That is some nice progress you have made there. I have not had the time to test it. I will test it very soon. According to your fork it looks very good. Did you send me a pull request to my github repository of ECWolf?

Still my hexen2 PR has not been merged with the RetroPie Project yet and that was months ago. I wonder if Jools Wills has his hands full with patching/updating the RetroPie Project.

Fine, I rather thought you gave up retrogaming.

ccording to your fork it looks very good. Did you send me a pull request to my github repository of ECWolf?

No I didn't send you a PR, I think it's better if you release the script module. Feel free to use the scripts and patchfile that I've created.

That is some nice progress you have made there. I have not had the time to test it.

I made some changes to .ecwolf interpreter.
With the ecwolf-files we are able to create a own system for ES and these give us back a kind of flexibility in usage.

PART 1 --- 1:1 interpretation of shell commands (as lines many as you like)
PART 2 --- ecwolf commands introduced by double dashes (only one line)
PART 3 --- last line as shell commands (only one line)

So for example

echo "We are starting Wolfenstein 3D without pak mods now ..."
sleep 5
cd wolf3d_14
echo "Next step is loading wolfenstein files"
--data wl6
echo "Thanks for playing...."

cyperghost

@tpo1990
I made some more tests
Even the both "Spear of Destiny" mission packs run fine
~~Just create both directories~~
~~* SOD2 for Spear of Destiny - Mission Pack 2 - Return to Danger~~
~~* SOD3 for Spear of Destiny - Mission Pack 3 - Ultimate Challenge~~

just use correct parameter set

--data sd2 for Spear of Destiny - Mission Pack 2 - Return to Danger
--data sd3 for Spear of Destiny - Mission Pack 3 - Ultimate Challenge

Works 100% with ecwolf :D

tpo1990

@cyperghost I would never give up on retrogaming, It is too big a part of my life now, just also need to take care of the vacation with my family :-)

Thanks that is very appreciated. I will take good use of it. I think once we have it all set i could create a pull request and see how it goes with the RetroPie project.

cyperghost

@tpo1990 I think it's a solid port of Wolfenstein and I wasn't aware that this can be converted to raspberry so elegant. So only thing I would suggest it to rahter download the whole package with wget and do ZIP extraction than to use hg. But that a thing that you decide on your own.

I would never give up on retrogaming, It is too big a part of my life now, just also need to take care of the vacation with my family :-)

Yes family first, then retropie projects... I was just a bit confused about your missing actions here. So enjoy your time.

Looking to the future and there may be a chance that ecwolf hopefully makes other great games useable (Rise of the triad, Corridor 7) and therefore a solid port should be considered ;)

As I said .... use the files from my git. The patch to setup the ESC key is a "must" in my opinion. Otherwise it's impossible to quit ecwolf without external keyboard or ssh command as long as you are in an active game (and furthermore, save, load features do also not work)

Consider also that different games use same savegame location and filenames so wolf3d1.4 in std. resolution can't load games from wolf3d1.4 in HQ mode and vice versa. Therefore I used the .ecwolf files. These do zip unzip jobs for the related savestates meanwhile.

So I uploaded all my ecwolf files to github.
They are avaiable here
But maybe it's easier instead of a line to line conversion to just handle this files as full grown scripts and make use of advanced shell commands... let me think about it.

tpo1990

@cyperghost I think so too. I might make some changes when i have created a pull request, since the scriptmodule must meet the demands of the RetroPie projects guidelines.

Rise of the Triad is already possible through @zerojay RetroPie extras. That game could also be enhanced further with the possibility of mods. I know for a fact that it is possible to get bots working as i have tried it on my windows PC with a special RotT edition. Corridor 7 could be interesting to get working thorugh ECWolf as well as Blake Stone.

I will probably test out your improvements later today, when i have the time. As always by working together we will make it possible. ;-)

I'm getting a few issues when trying to compile ECWolf on my RPi2.

The first issue is when the scriptmodule tries to clone ECWolf's repository via hg (Mercurial). It's strangely giving me the following error:

user@leomontenegro:~$ hg clone https://bitbucket.org/ecwolf/ecwolf
aborted: error: _ssl.c:510: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

I don't know if it's some kind of maintenance in Bitbucket, or if it's permanent due to some security changes related to SSL versions. My workaround for this is going to the ECWolf repository's Downloads section, and then clicking on the link Download repository. Luckily, this should give me the source code, so I can proceed with the other steps manually. However, with the "build_ecwolf" function not working, users trying to install ECWolf through this scriptmodule won't succeed on that task.

The second issue is about @cyperghost's patch for mapping ESC key to controller. After downloading source code via browser from bitbucket (since I got the SSL error above), I tried applying the patch. However, it gave me the following error:

user@leomontenegro:~/zxc/ecwolf-ecwolf-5065aaefe055$ patch -p0 -i wl_play_patch.diff
patching file ./src/wl_play.cpp
Hunk #1 FAILED at 73 (different line endings).
1 out of 1 hunk FAILED -- saving rejects to file ./src/wl_play.cpp.rej

I don't know if it's something strange in the patch itself, or if the guys on ECWolf's repository commited some changes that breaks the patch. But since the changes inside the patch are minimal, I simply edited wl_play.cpp and made the changes by myself. Hopefully, it should work.

cyperghost

@Solid-One no it's the file format of the cpp file or the patch file.

EDIT: USE INSTRUCTIONS IN NEXT POSTING ---> here
I rather think it's better to transform the patch file then to change the format of the source file.

Try dos2unix ./src/wl_play.cpp~~and if this does not work apply the same command to patchfile itself dos2unix wl_play_patch.diff ... how did you get the patch? By copy or paste or by wget command?~~

EDIT:
works like descriped!
The source code is written in windows style :(
I prepared the patch on unix system - therefore the mismatch but as long as there is no official PR I don't know if there is a difference between wget-zip download or hg git download :p
