openfodder's Issues

Shots have no sound in the game

Shots are silent in the game. Is it the normal working?

Is there any way to debug the executable in runtime?

Is there any way to debug the C++ code, or the executable file in Linux to see when what's happening?
I'd like to see in which files are being read, written so on?
In eg. Python it is possible to go line by line during runtime.

[windows] Get data from program directory

It would be great if OpenFodder could get its data from the directory it's in on Windows.

Currently, if i try to put the Campains/, Data/ and Save/ directories in the same path where OpenFodder.exe is, the program starts, but it only shows custom campaigns and then even cannot starts one of those custom levels (direct death).

The Windows setup i am using on this is XP based. But as the program runs up to the menu (with full action there), i don't think XP would be the cause of this.

Thanks in advance, and for all your work on this. 👍

Support for 3DO version

Describe the solution you'd like
Support for the 3DO version of Cannon Fodder

Additional context
Video of 3DO version

"SDLAudioP2" received signal SIGSEGV, Segmentation fault.

Describe the bug
I appear to have triggered some sound related crashes. Plus a crash on exit.

To Reproduce
I believe it's triggered by the launching of some of the bonus amiga levels - which don't appear to feature any music - then hitting ESC to go back to the main menu.
Do it enough times and it sometimes bombs the game or stops the music from playing.
If I click on the about screen or the cannon fodder 1/2 campaigns I don't seem to trigger it.

Expected behavior
You'd expect the main menu music to reset from the beginning when closing any of the campaigns/levels but you end up with silence. After it starts doing this you still don't get any music if you launch the cannon fodder 1 or 2 campaign.

Desktop (please complete the following information):

• OS: Debian Linux
• Version: Testing (Buster)

Additional context
I compiled a debug version of the game by changing the makefile:
CC = clang++ $(CXXFLAGS) -c -g -O0 -Wall -std=c++14 -ferror-limit=100 $(pathInc) $(Libs)

I've attached some logs with backtraces by using gdb OpenFodder:
openfodder1.log
openfodder2.log
openfodder_crash_on_exit.log

Hopefully those help. OpenFodder otherwise appears to be reliable and faithful to the original games. You can even shrink or increase the window size with the plus and minus keys - found that by accident!

Cheats

Would it be easy to add e.g. god mode just for fun?

Need help compiling and running game

I was surprised to find an Open project on Cannon Fodder, and more surprised still to see it past 1.0! Congratulations.

I can't seem to find any instructions (or discussion) about this game or how to compile it. When I run the .exe in VS2017, I get The program '[12304] OpenFodder.exe' has exited with code 1 (0x1)..

Here is the whole output, if that helps.

Compilation on linux + a couple of questions

Hello there,

First and foremost, thank you very much for creating this project! Cannon Fodder was one of my favorites back in the Amiga days, and probably one of the games I sunk the most time in during my youth, along with two other classics, Sensible Soccer and Chaos Engine. It's great to have it available again under a free software engine, along with a map editor!

I've been previously running OpenFodder on Windows, but I would like to know if it would be possible for you to provide compilation instructions for Linux. Currently there is no documentation specifying the required libraries and additional instructions for compilation, and I think it would be nice if these could be included in the readme or a separate file.

Secondly I would know if a universal Linux Snap/AppImage package could be provided for future stable builds.

Thirdly, and as a more impertinent request, since you've done such a great work with Cannon Fodder, any chance you can eventually give a similar treatment to Sensible World of Soccer? There's still a huge community playing the game online, mostly using shaky emulators with poor multiplayer capability, and an free software port for it would certainly be more than welcome!

That's it for today. Please continue the amazing work and a have a nice day!

to release 1.0

Both x86 and x64 built:
By CF1 stuff, Amiga version:

1. Missing Animation into Briefing Screen (helicopter landing)
2. Heroes and Squad writings into Hill Screen are like dos appearence instead original amiga appearence.
3. Soldiers animation into Hill Screen goes wrong (first soldiers don't get down from the footpath)
4. On Save Screen, the prompt cursor is corrupted (it shows another part of sprite sheets, seems some people sprites)
5. On Load Screen the writings don't have square red/green borders

By CF2 stuff, DOS version:

1. No sound (maybe a wrong my configuration?)
2. "Try Again" animation has half ufo sprite on the right of the writing
3. Briefing Screen on first missions (middle-east) don't have to have the ufo landing
4. Is there a somersaulted car on extreme right of level 1 (Map1)?!?

Support for DS4 controller via SDL

Hello
Any plans for Support for DS4 controller via SDL ?

Compilation on Raspberry Pi requires -fsigned-char

When compiling latest OpenFodder on a Raspberry Pi 2, I received a ton of errors regarding a "constant expression evaluates to 255 which cannot be narrowed to type 'int8' (aka 'signed char) [-Wc++11-narrowing].

I had to add -fsigned-char into the CC = line in the Makefile to get it to compile properly.

OpenFodder.exe only runs as Admin on Windows 7

Reduce requirement of Cannon Fodder 2 files

From Issue #32 from andrew-mcmahon

"I couldn't see any terminal output listing missing files when I ran the game so I was wondering why Cannon Fodder 2 wasn't showing up (I only copied CF_ENG.DAT to Dos2_CD)"

We should reduce the requirement from all files down to just CF_ENF.DAT, as it can use the Amiga music instead of the PC files, making all the PC files not necessarily required.

Cannon Fodder: German DOS floppy version support

I recently got my hands on the German DOS version of Cannon Fodder and noticed that it is not supported by OpenFodder.

The first floppy disk contains CF_GER.DAT, so I tried to rename that to CF_ENG.DAT and put it into a Data/Dos_CD subdirectory for a quick test. I also changed the MD5 hash in https://github.com/OpenFodder/openfodder/blob/master/Source/Versions_Files.hpp#L31. The game unfortunately didn't start, the output can be seen below.

1.5.3 segfault on OpenBSD

Describe the bug
OpenFodder 1.5.3 segfaults after clicking on Cannon Fodder from the main menu. GDB backtrace attached.
Additionally (though perhaps unrelated) Cannon Fodder 2 does not appear in the list despite having CF_ENG.DAT from CF2 in $HOME/.local/OpenFodder/Data/Dos2_CD

To Reproduce
Steps to reproduce the behavior:

1. Build OpenFodder 1.5.3
2. Launch it
3. Click on Cannon Fodder on main menu

Expected behavior
Game loads.

Desktop (please complete the following information):

• OS: OpenBSD
• Version 6.4-current

openfodder.log

Separated user and program directory

A make install routine which would install things into

• /usr/bin/openfodder
• /usr/share/openfodder

and store save games as well as game data in user writable standardized folders as specified by https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html would be great.

Libretro support?

Thank you very much for bringing back such a beautiful game for us!

Switching from JSON/INI to YAML as format for configuration/customization

Currently openfodder uses JSON for describing campaigns/mission and INI for configuration. I propose to switch to YAML as more human-friendly format.

Here example of campaign in YAML format:

---
Author: Sensible Software
Name: Cannon Fodder
Missions:
  - Name: THE SENSIBLE INITIATION
    Phases:
      - Aggression:
          - 0
          - 0
        MapName: mapm1
        Name: IT'S A JUNGLE OUT THERE
        Objectives:
          - KILL ALL ENEMY

Generating "Random Game" Level -> Another Window Opens -> Crashes To Desktop

I have a Windows 10 machine with (only) the GOG version of the 1st Cannon Fodder game installed. Running this in OpenFodder works.

Whenever (1) I click on OpenFodder's menu option to play a random game (not just a random level), (2) text appears to indicate all? steps of generating the 1st level of this game have been processed, then (3) an extra small window appears (it appears to be blank with a black background, but it only appears briefly); (4) this new window closes; & (5) OpenFodder crashes to desktop.

This is more of a question than a suggestion for feature, but you can take as such if you will: Is it possible to make a custom soldier names mod that perhaps from an ASCII text file with one name per linebreak?

To contribute some more, in the SNES version it's straight-up stored in text format, 6-characters long, A-Z (all caps), doesn't support numbers nor symbols, low caps results in a different text color (highlighted) with an "offset" to which character correspond to what ("o" becomes golden "K"), needs a space to fill the blank.

So a name like COOKS is perfectly fine, but Coffee, Max!me, BL0RB1, PIZZA are not

Helicopter intro not scrolling smoothly

Hi!

I am at last using my own built GNU/Linux version of OpenFodder. Its built against latest SDL 2.0.10, etc and works fine.

However, I have observed that the helicopter intro sequence is not smooth as in Amiga and RiscOS (RiscOS version runs natively on the Pi, BTW!).
The game originally synced video during this sequence to vsync, so it was ~50FPS, while OpenFodder seems to be doing about half-the-framerate, which in a modern display would be ~30FPS.
I am sure the solution would be to allow OpenFodder to render this sequence "as fast as possible", so SDL2 blocks on the rendering function: SDL_RenderPresent() is synchronous so it blocks if VSYNC is ON until VSYNC arrives.
DO NOT rely on SDL_Delay() for video speed control, because it will generate micro-stuttering in this smooth scrolling sequence: let the game sync to vsync, so video will be smooth no matter what exact physical display rate is.

How to create Track2.flv

The readme says "Extract Track2 from the CD and name it 'Track2.flv', placed in the Amiga_CD folder."

I wonder how to actually do this. What kind of file format is "flv" and how to create it? Could you please also provide a checksum of the resulting file?

Automatic script updates

Scripts are dynamic in a sense, we should have a mechanism which at least checks if the scripts are up to date, and possibly downloads them if not.

Random map completing level screen

After beating some random map it shows default ending screen.
Would be nice to replace it to regenerating another map instead.

PC Helicopter Intro broken with custom camera tile count

Describe the bug
The helicopter introduction screen is broken on PC data if you use --columns or --rows parameters

Expected behavior
Helicopter background renders correctly

Additional context
cGraphics_PC::Mission_Intro_Render_2
cGraphics_PC::sub_15B98

Both these functions are hardcoded for a screen surface of 320x200

We need a new home page for openfodder.com

Our homepage is terrible.

We need a real one!

Saves aren't working

I just played through 10 missions of Cannon Fodder 1, saving after every mission, and when I went to load there were no saves. Sure enough the C:\Users\Dan\Documents\OpenFodder\Saves folder is empty. :(

Portable variant of OpenFodder

Basically a version that doesn't need to need to be installed, just copied into a folder somewhere (or into a USB Stick) and run from there. Also with a configuration tool for setting up paths.

How to play normal 1 player game? (Original Amiga CF1 campaign)

Hi there!

I have just built latest GIT version of OpenFodder, but I dont seem to be able to play the original Amiga campaign (intro, then hill, then first level, etc...)
All I can see upon running the executable is a menu where I can select a level!
My original AMIGA data lives in ~/openfodder/Data/Amiga, as per instructions.

Thanks!

Some segfaults on OpenBSD (backtraces included)

Hello --

I would like to make a package of OpenFodder for OpenBSD. While the game compiles fine, it crashes while playing. There are two backtraces here, and I will explain both.

1. The openfodder-opening.txt backtrace is what happens if you let the opening cinematics play. After a second or two, the game crashes. If, however, you click to cancel the cinematic before the crash occurs, the game will successfully launch.

2. The openfodder-level2.txt backtrace is what happens once level 2 loads. Level 1 plays perfectly.

For completeness, I am using the GOG.com version of Cannon Fodder.

Let me know if you need anything more.

Prevent friendly teammates from using rockets/grenades when left alone

Remember that fun time when you left your teammates with a stash of 6 grenades + 4 rockets which you needed to win the mission - but they decide to fire them all at something relatively harmless and/or blow themselves up in the process?

I wouldn't mind seeing this as a option that could be toggled on or off.
Granted it was part of the charm of the game - perhaps it's heresy to even suggest the change - but it could get a little bit annoying at times.
A slightly iffy workaround was to load all/most of the munitions onto a single man but then you were stuffed if he took a rocket to the face.

openfodder fails to compile under Gentoo Linux

Just making sure... no sound from DOS (GOG version)

Just making sure I'm not crazy. Reading over the code, it seems like there's no mechanism for finding and playing the music from the DOS version of the game (I'm using the GOG version).

It's OK if no. The OpenBSD package can just tell the user to go find their own music assets and put them in the right place. I'm double checking to make sure I didn't miss anything.

Auto detect GOG installation

Instead of manually selecting where the game data is installed, open fodder can detect where they are installed.

Here is a C header that allows searching for GOG game installations from the windows registry, given the game id: https://github.com/cxong/find_steam_game

License?

Would like to see some package in Fedora (or any other Linux distribution). Therefore, this source needs a valid FLOSS license. We recommend to use GPLv3.

Cannon Fodder 2 detection

Hi!

I am unable to get CF2 to get detected, i have tried to put all data in the Dos2_CD directory and only CF_ENG.DAT. No difference.
Is there different versions of CF2?

Some things from the Game Boy Color that could be considered for (optional) enhancement.

I've been playing the GBC version and noticed a few things from the get-go that could be interesting to implement:

1. It's constantly in a 2-men cell mode. This has two pros and con: it's easier to manage, minimizes losses, doesn't have units limit (as long as there is recruits at the base, you can keep throwing them at'em), BUT you can't split the team.
2. Building capacity limit. In the GBC the buildings can't be destroyed really, you can throw a grenade to force everyone inside to come out, but it's two or three men that are in, meaning the building destruction is optional.
3. Because you can't see the whole map, the pause screen has a "Scan Radar" that shows blips of enemies that are within a wide area (presumably within 256 pixels from the player?). As a feature the scan radar could appear in a corner and not needing to pause to check, also diminishing the need of map checks.
4. When grenades are "required", there's a crate conveniently placed near the drop point (except in Mission 2 Phase 2 for unknown reasons). Perhaps this idea could be taken into account for a "map patch" that can be optionally applied before starting a campaign (or, alternatively, just have a "start with grenades" option)

Final phase of final mission (CF1) crashes

OpenFodder crashes at the beginning of the final phase of the final mission (Deathtasticelastic). The screen fades in, scrolls to the right, then crashes.

I've reloaded my latest save, F10 ended phase my way to the last phase twice, and every time it crashes.

This also happens if I skip straight to it with the -m 24 -p 6 parameters.

Does this engine require any custom royalty-free assets? Because I could make them...

Is your feature request related to a problem? Please describe.
This game/engine already uses the copyrighted assets from the original. Even without owning the original games.
Despite the demos being free, they ain't exactly in that "white" zone of legal usage.

Describe the solution you'd like
I want to volunteer to make royalty-free assets of all of the copyrighted material currently used in the engine, in order to remove any possibilities of Codemasters filing a suit for infringement.

Maybe even a few custom MIDIs, and some royalty-free (good) sound effects.

Describe alternatives you've considered
Just to make a new logo for this engine/game.
Or maybe a custom mission/map pack that comes with the engine/game. All of which are completely original, and free.

For the logo, I've considered a new Poppy, or some weapon, or something.

Additional context
What I'm aiming for here is the exact same thing FreeDoom achieved.
