Reimplementation of Gothic 2 Notr

OpenGothic

Open source re-implementation of Gothic 2: Night of the Raven.

Motivation: The original Gothic 1 and Gothic 2 are still great games, but it's not easy to make them work on modern systems. The goal of this project is to make a feature complete Gothic game client compatible with the original game data and mods.

---

Work in progress

Development is focused on Gothic 2 and new features are not tested for Gothic 1 compatibility. While Gothic 1 is not officially supported pull requests that fix Gothic 1 — and general — bugs are welcome.

The original game has been replicated fully; you can complete both the main quest and the addon. Check out the bugtracker for a list of known issues.

OpenGothic is designed to utilize features of modern graphic hardware and api's like mesh shaders or ray tracing. While mesh-shader not mandatory, yet don't expect OpenGothic to run well on low-end or outdated graphic cards.

Prerequisites

Gothic 2: Night of the Raven is required as OpenGothic does not provide any built-in game assets or scripts.

Supported systems are:

• Windows (DX12, Vulkan)
• Linux (Vulkan)
• MacOS (Metal)

How to play

Windows

1. If not already done install Gothic. OpenGothic comes with auto-path detection if your Gothic files are in a common path.

   • "C:\Program Files (x86)\JoWooD\Gothic II"
   • "C:\Gothic II"
   • "C:\Program Files (x86)\Steam\steamapps\common\Gothic II"

2. Download OpenGothic and extract into a folder of your choice. Available options are:

   • A Pre-Release (recommended)
   • Alternatively a recent test build from CI

3. Run Gothic2Notr.exe.

   If nothing happens check log.txt and look for the line invalid gothic path. In this case OpenGothic fails to find your Gothic installation and you have to explicitly specify its location via -g paramter. Either you create a shortcut to Gothic2Notr.exe and change the target line in Properties to e.g.

   Gothic2Notr.exe -g "C:\Program Files (x86)\Steam\steamapps\common\Gothic II"

   or you can edit Gothic2Notr.bat and run this file instead.

Linux

1. If not already done install Gothic via Wine/Proton or copy the game files from a Windows installation.

2. You can download a build from CI and extract into a folder of your choice. Alternatively OpenGothic can be built manually. For Arch the AUR provides a 3rd party package.

3. Run Gothic2Notr.sh -g "~/PlayOnLinux's virtual drives/Gothic2_gog/drive_c/Gothic II" (example path, use path to your Gothic installation instead)

   You can edit Gothic2Notr.sh and change the line exec "$DIR/Gothic2Notr" "$@" to

   exec "$DIR/Gothic2Notr" "$@" -g "~/PlayOnLinux's virtual drives/Gothic2_gog/drive_c/Gothic II"

   to not have to enter path manually every time. Then run Gothic2Notr.sh without arguments to start.

MacOS

1. If not already done install Gothic. Instructions how to obtain the game files can be found here. OpenGothic comes with auto-path detection if your Gothic files are in "~/Library/Application Support/OpenGothic".

2. Download a build from Mac Source Ports and follow the installation instructions given there. Alternatively recent test builds are available from CI that can be extracted into a folder of your choice. You can compile a fresh build as well.

3. Run Gothic2Notr.sh

   If OpenGothic fails to find your Gothic files you have to explicitly specify its location via -g parameter. Change the line exec "$DIR/Gothic2Notr" "$@" to reflect your Gothic path e.g.

   exec "$DIR/Gothic2Notr" "$@" -g "~/PlayOnLinux's virtual drives/Gothic2_gog/drive_c/Gothic II"

---

Modifications

Mods can be installed as usual. Provide the modfile.ini to OpenGothic via -game: parameter to play. Example:

Gothic2Notr.exe -game:Karibik.ini

What's working?

Content mods (retexture/reworld/animations) that only rely on regular scripting and do not use memory hacking.

What's not?

• Ikarus/LeGo

There are ongoing efforts to support parts of it to make at least some popular mods like Chronicles of Myrtana playable. Progress can be tracked in the corresponding issue. An explanantion how Ikarus works is given here.

• Union (32 bit and Windows only, not possible)
• DX11 Renderer - same as Union, but don't worry - OpenGothic has nice graphics out of the box
• AST sdk
• Ninja

Video

Available Graphic options

Game menu in gothic is done by scripting. While orignal graphics settings do not apply to current-gen graphics, engine redefines meaning for some of tweakables:

• Settings -> Extended configuration
  • Cloud Shadows mapped to SSAO.
  • Radial Fog mapped to "Volumetric fog"
  • Reflections reused, for screen space reflections
• Settings -> Video settings
  • Internal rendering resolution, for 3D, can be altered here. UI and text is always rendered at full resolution.
• Application command line:
  • Ray tracing: setting affects only capable hardware, off by default for igpu's, add -rt 1 to enable

Rendering distance is not customizable.

opengothic's Issues

Case sensitiveness issue on linux

Hello.

First of all: Wow. This is an amazing project. Thank you for this.

I tried to compile and start the project on a linux machine.
After installing CMake 3.12 from a third party repo (kitware) and installing glslang-tools it built very smooth with only one warning so far. Nice.

After starting a new game, it turned out, that the player controls were'nt working. I debugged a bit and discovered that

std::unique_ptr<IniFile>                baseIniFile;
std::unique_ptr<IniFile>                iniFile;

couldn't be found. Therefore all control keys were unset.
The reason, why the files could'nt be found, was the following:
In my installation (German CDs: Gothic II Normal + Addon) the folder and ini file was named in different case:
"System/Gothic.INI" instead of "system/Gothic.ini".
After I renamed the folder and the file, the player controls has been working.

For a general solution, I digged myself down in the code and made the following observations:

1. I found pieces of code, that might be required to solve the problem in the following places:

• Game/utils/fileutil.h: exists
• Game/utils/fileext.h: hasExt, exchangeExt
• Game/gothic.h: caseInsensitiveSegment
• lib/MoltenTempest/Engine/utility/dir.h: scan

2. String conversions are done at various places and the usage seems to have been mixed up sometimes (I've seen so far: char*, std::string, std::u16string, unicode 8 conversion being used as std::wstring). That's just a subjective impression.

I want to offer you the following changes, but want to ask for your opinions beforehand:

• Implementation of dedicated String classes, that are inheriting from the std::string, std::wstring, etc. and implement support functions, that are required at different places (toUpper, toLower, indexOf, equals, replace, trim, conversion from string/wstring/u16string,u32string to each other string).
• Implementation of a path class, that would be an specialization of the upper listed String class, that handles often required functions: getFilename, getExtension, getFilenameWithExtention, isAbsolute, isRelative, dirUp or concatenation of paths.
• After that an explorer class might be useful, to search for files / directories recursively or not and case sensitive or not. This class might be implemented with std::expermimental::fs features that should be available at >= c++14.

What do you think about that approach ? Do you want to have it done that way ?
The way of not specializing the std::string and using more static support functions might be a good approach, too. It would look more like the std::string instead of yet another custom util string.

I'm curious about your opinions 👍

Allow user to use any work directory, to start the game

Right now game expect to find shaders, fonts at "./data/*" - need to detect self-directory for *.exe location.

Possible integer overflow in InventoryMenu::onTakeStuff

Miss this minor issue on code review:

void InventoryMenu::onTakeStuff() { 
  uint8_t itemCount = 0;
  auto& page = activePage();
  auto& sel = activePageSel();
  if(sel.sel >= page.size())
    return;
  auto& r = page[sel.sel];
  if(lootMode==LootMode::Normal) {
    ++takeCount;
    itemCount = pow(10,takeCount / 10);
    if(r.count() <= itemCount) {
      itemCount = r.count();   // <<----- HERE: uint8_t = size_t
      takeCount = 0;
    }
  }

While it's hard to meet this condition in real game, still should be fixed

Implement lock-picking minigame

Expendable items usage

1. Fix spell-scrolls usage: for now player can cast spell unlimited amount of times
2. Fix documents/books usage: notes disappear from inventory, after reading

Equipped items should be on separated stacks

Build failed on Linux with error: clearing an object of non-trivial type

Actual master code build fails on Linux with gcc version 9.2.1 (on Arch Linux). Build fails on file zCModelMeshLib.h with error:
error: ‘void* memset(void*, int, size_t)’ clearing an object of non-trivial type ‘ZMath::float3’ {aka ‘struct ZMath::t_vector<ZMath::t_float3, float, float, float>’}; use assignment or value-initialization instead [-Werror=class-memaccess] 37 | memset(&m_RootNodeTranslation, 0, sizeof(m_RootNodeTranslation));

Problem lies here:

memset(m_BBox, 0, sizeof(m_BBox));
memset(m_BBoxCollision, 0, sizeof(m_BBoxCollision));
memset(&m_RootNodeTranslation, 0, sizeof(m_RootNodeTranslation));

It's more warning than error because use of memset to init memory of non-trivial types probably sometimes can fail (not in this case since other builds works) but source code is compiled with -Werror option so warnings are treated like errors. Didn't checked whole source but probably there are more places to fail with similar errors.

PS: After removing -Werror option from CMakeLists.txt compilation ended successfully.

Aim of this project is not clear

Hey there,

this might be a noob question but I wanted to ask what's the goal of your project. This project got mentioned on reddit and worldofplayers and by REGoth devs and I'm unsure what to expect. You write DX11 can't be run with this "client-app" but you will provide some graphical features like shadows it seems. I wonder if this could compete with DX11 mod and if it would be as good or better performance-wise.

Here in short what I would expect of a reimplementation:

• better performance, so game could be run on modern hardware w/o bottlenecking
• graphical features like shadows, grass, HBAO, tesselation and so on
• cross-platform playability or at least smooth to be run on W10

Greets

Dialogs database detection

WorldScript::loadDialogOU still use acii path to dialogs file

Effects pipeline: finalize beliar-sword related fetures

1. lighting look wrong to me (MFX_BELIARSRAGE_FLASH)
2. explosion is not there (driven by MFX_BELIARSRAGE_TARGET)

Npc_CanSeeNpc returns wrong value, when npc sitting on a bench.

Seem like Npc_CanSeeNpc should use BIP01 rotation, to calculate eye-dir vector.
B_AssessTalk :

		if(Npc_CanSeeNpc(self,other))
		{
			AI_StartState(self,ZS_Talk,0,"");
		}
		else
		{
			if(Npc_IsInState(self,ZS_ObservePlayer))
			{
				AI_Standup(self);
			};
			AI_StartState(self,ZS_Talk,1,"");
		};

Remove from world characters with empty/invalid TA-list

1. Have to reproduce behavior of original G2
2. There 4 guards at the city gate, instead of two

Random Segmentation fault on Game save [linux]

If the game is saved, theres a ~25 % chance to get a segmentation fault.

File: MoltenTempest/Engine/gapi/vulkan/vframebufferlayout.cpp
On current master line 38

bool VFramebufferLayout::isCompatible(const VFramebufferLayout &other) const {
  if(this==&other)
    return true;
  if(attCount!=other.attCount) //SIGSEGV on game save
    return false;
  for(size_t i=0;i<attCount;++i)
    if(frm[i]!=other.frm[i])
      return false;
  return true;
  }

It can be reproduced with starting a game and saving it ~3-4 times.

Can't save the game [linux]

I tried to debug it some time now, but this seems to be a bit tricky.

So here are the infos I got:

• Terminal output says: "loading error: unable to open file"
• Inside the game, the text is displayed: "unable to write savegame file."
• A savefile is created with filename: save_slot_1.sav and it has 963,7 kB. It's located beneath the Gothic2Notr executable.
• One time I saw, he stopped in bool GameMenu::implUpdateSavThumb(GameMenu::Item& sel)
  while reading the SaveGameHeader. He wanted to read 4 but only read 0.
  The callstack looked like this was another thread.

Not easy to find, but it smells like a race condition, or ?
I'll continue searching, but maybe you already have an idea.

OpenAL crash on startup

Hi, I just found and want to try this awesome project! But I have a problem with launching the game.

I'm running the command

./Gothic2Notr.exe -g "D:\Steam\steamapps\common\Gothic II"

which immediately outputs

AL lib: (EE) WinMMOpenPlayback: waveOutOpen failed: 1

---crashlog(std::system_error(No device))---
GPU: ?
[no call frames available]

By googling that error, it looks like it comes from external lib OpenAL (winmm.c#L328). Some incompatibility with my sound card maybe? I don't know, but I tried two different Gothic II Notr versions, so it shouldn't be the problem. I'm using Windows 10.

"lost device!" on startup

I compiled OpenGothic on Linux and - after some fiddling with the files - I managed to get the game into a state where strace doesn't report any obvious file not found errors any more. However the game is now stuck with the following output:

no *.ini file in path - using default settnigs
no *.ini file in path - using default settnigs
GPU = GeForce GTX 960
Depth format = 6 Shadow format = 4
lost device!

I assume this has something to do with Vulkan, but I have no experience with it. I can only tell that other Vulkan games are running perfectly fine.

Is the game supposed to at least start on Linux, or is this expected?

It tries to open /home/swick/Games/Gothic 2 Gold/_work/Data/Scripts/_compiled/Fight.dat but it doesn't exist. FIGHT.DAT however does.

Detect Gothic minor version

In "Night of the Raven", there was a behavior change for AI-State scripts.

1. Need to detect ZEngine version expected by game scripts
2. If AI script missing {STATE}_Loop function:

• NOTR - endless ai-state
• Others - one-time ai-state

Tests cases: ZS_DEATH; ZS_GETMEAT

[Linux] Mouse Camera Move Only Goes Left to Right

This is to track the Linux issue I found where with the X11 improvements (Try/Tempest#8), the mouse camera only goes left and right, instead of along with up and down. You can assign that to me if you'd like, and I'll research what could be happening.

Crash with Gothic II (GOG)

When I try to start OpenGothic, the window opens and closes a second later. This is all what's written into crash.log:

---crashlog(ExceptionFilter)---
GPU:
0x00486ce2: CrashLog::dumpStack(char const*) in C:\open_gothic\bin\Gothic2Notr.exe

CMake install missing for Gothic2Notr binary and MoltenTempest shared object

Right now make install completely fails for a number of reasons:

1. an install macro for the Gothic2Notr binary is missing so the binary doesn't get installed at all
2. an install macro for libMoltenTempest.so is missing. Alternatively MoltenTempest can switch to building a static library instead.

Running directly from the build dir is also broken on linux. If you want to link MoltenTempest as a shared library, LD_LIBRARY_PATH has to be set to the CMAKE_LIBRARY_OUTPUT_DIRECTORY directory in a wrapper script (or you start linking it statically).

Another point is that you should not overwrite CMAKE_BINARY_DIR at all! The user chose the build dir for a reason. You can still support running from the build dir.

[Linux] Case sensitiveness while loading music

Some sound files can't be found on linux systems, due to case sensitiveness issues.
As the music filenames are coming from Deadalus Scripts, I guess, the engine should deal with that issue.

Example output:

unable to load sound: "nw_daystd_A0.sgt"
unable to load sound: "nw_dayfgt.sgt"
unable to load sound: "nw_daystd_A0.sgt"
unable to load sound: "nw_dayfgt.sgt"

Files exist here: Gothic II/_work/Data/Music/NewWorld/NW_DayStd_A0.sgt.

As a proposal, I made some changes that carry out the Gothic::nestedPath feature to the OpenGothic/utils/fileUitls part and enable the musicLoader to use the case sensitive file search, too.
I'll create a PR for that change, so that it can be discussed in there.

instanceDataHandle proper cleanup

Have to null all .instanceDataHandle references to C_Npc/C_Item, upon deleting

IceBlock spell not stunning main hero

Faster loot

1. If player hold action-button, the number of items to take has to be increased *10, for every 10 take action
2. Need to implement take *10, take *100 hotkeys

Lucia(from bandic camp) has a weapon in her foot

Most likely something wring with animation-skeletion.
Engine always use a "ZS_SWORD" bone-socket to emplace one-handled weapons. Somethings goes wrong...

Non english game text

For now game font menu.ttf/main.ttf have no support for non-english letters.
Workaround: replace font files

Cross-platform support?

I'm wondering if cross-platform support is planed for the future, in particular if this should run in Linux.

Thanks!

Add COW strings for script

Need to optimize string operations in AI-scripts:

if(Hlp_StrCmp(Npc_GetNearestWP(self),self.wp) == FALSE) <-- copy string on stack
{
  AI_GotoWP(self,self.wp);
};

Implement script-driven SVM module

script: https://github.com/GothicII/EnglishCleanedScripts/blob/700415d1eed914239ebc9cfdce615b4eccce2567/Content/Story/SVM.d

Seekers doesn't work

Dialog with them never starts automatically.

Finalize support for Rooms/Portals

Need to improve 'room' detection, so script api can work properly.
Offended api:

• Wld_AssignRoomToGuild
• Wld_GetPlayerPortalGuild
• Npc_GetPortalGuild

For now implementation of Npc_GetPortalGuild reduced to GIL_NONE or GIL_PUBLIC.
