unitydoorstop's Issues

Doorstop not working on first Steam Launch.

Hi, i'm still facing the issue #5 with Raft.

When opening the game through steam the first time, it does not load at all, i think it might be related, could we have a setting to toggle the double injection ? my code anyway checks if its already loaded.

Missing proxy.c and dllproxy.asm on master

Hi, I'm just sending this issue because these two files seem to be missing in the latest version of master, I had to revert to older versions to be able to build the library

"Step Over" bug

It's great that we can connect dnSpy without a patched mono.dll, but the "step over" bug still persists without it. Any chance to implement that fix into Doorstop?

Please add that Doorstop.dll must be netstandard2.0 and not net7.0 in the documentation

Hi, I didn't test with all dotnet versions, but when I compiled my Doorstop.dll (with my default net7.0) it crashes with the log below (pasting it here for future google searches), I tested multiple games.
After a few hours of trying, it occurred to me to try with netstandard2.0 and then it worked. So please add some indication to this in the installation instructions. Thanks.

Mono search paths - multiple overrides and replace full mono search path

Allow multiple directories for mono_dll_search_path_override and allow to remove the target_path_folder and root_dir.

Maybe something like this (inspired by AssemblySearchPaths in csproj):

mono_dll_search_paths=Z:\MostImportant;{override};{target};{root};D:\Fallback
mono_dll_search_paths=A:\TheOneAndOnly
mono_dll_search_paths=

quick overview of what is happening currently:

    if (has_override) {
        strcat(mono_search_path, override_dir_full);
        strcat(mono_search_path, PATH_SEP);
    }
    strcat(mono_search_path, target_path_folder);
    strcat(mono_search_path, PATH_SEP);
    strcat(mono_search_path, root_dir);

The "fallback" case is there to avoid when future updates of the game suddenly introduce their own versions of the assemblies.
The "one and only" or "nothing" cases would allow using dynamic AppDomain.CurrentDomain.AssemblyResolve to programmatically resolve everything. (These are theoretical ideas that were not tested, so might not work well with Unity mono)

output_log being written to C:\User\ouput_log.txt

Hi, on some system of my users or on my dedicated server running win server 2022, for some reasons the redirect output log redirects the output log to C:\User\output_log.

Any idea why this happens ? the doorstop dll is next to the game, works perfectly but for some reasons this happens.
Here's my full path in case it can help.

Not loading mono.dll IL2Cpp on Windows 2019?

Have a release zip include all archs and versions

As part of the ModTek release, I include all ARCH variants. To make debugging easier, I would also like to include the verbose variants in a subfolder ready just for copy/pasting.

Right now as part of the build process of ModTek, it has to download three zips from here, and it would need to download three more for the verbose variants.

It would be simpler to just have one zip with all variants.

Doorstop does not work on Valheim

Valheim is a 64bit Unity 2019.4.16 game.
With Doorstop_x64_3.0.2.2, the game just crashes immediately
With Doorstop_x64_3.1.0.0, the game starts, but the targetAssembly appears to not be running at all
I have tested with BepInEx (with the newer 3.1.0.0 dll) and the example Doorstop.dll (moved to the game folder per the path in doorstop_config.ini), doorstop_is_alive.txt did not appear
I have tested Doorstop as winhttp.dll and version.dll, neither worked
Doorstop itself appears to work, setting redirectOutputLog=true does result in an output_log.txt, just not the targetAssembly

Error message unreadable (Error invoking code)

I'm having problems debbuging an error message.

Info:
Game: Little witch in the woods
OS: Win 10
Visual Studio 2019 (used to build the entrypoint [release mode])

Steps to reproduce:

Using the Example entrypoint class in the README.
Placed winhttp.dll and .ini files in the game's root directory
Placed entrypoint in LWITW_Mods/net5.0/LWITW_ModLoader.dll
Changed ini file to reflect the entrypoint location.
Run the game and get this error:

(changed private information to ...)

As you can see, that error message is pretty much unreadable.

Note: not sure if this is worth anything, but the dll is not 4096 bytes in size, it's actually 5K, let me know if that is a problem

Any help?
Thank you

Version.dll missing.

I seem to be misunderstanding how Doorstep is supposed to work. The instruction all say to copy version.dll to the game folder, but I do not see version.dll in any release for Doorstep.

In addition, when I build Doorstep in VS 2019, no version.dll is created. A proxy.dll is created, but I do not know what to do with that file. Should it be renamed to version.dll?

Also, I had to change the pre-build event because the paths in the arguments to the powershell script seemed to be missing quotation marks. The following is what I changed it to to get it to build without error (note the quotes on the -File, -projectPath, and -templatePath arguments):

powershell.exe -ExecutionPolicy Bypass -NoProfile -NonInteractive -File "$(SolutionDir)\scripts\genproxy.ps1" -projectPath "$(ProjectDir)" -templatePath "$(SolutionDir)scripts" -arch $(PlatformArchitecture)

I don't know if this would cause my issue or not.

For reference I am trying to mod the game 7 Days 2 Die.

--doorstop-mono-debug-suspend true

Hi, I'm starting by game process with the additional command line args:
--doorstop-mono-debug-enabled true --doorstop-mono-debug-address "0.0.0.0:55555" --doorstop-mono-debug-suspend true

All works as expected, I'm able to connect to the port 55555 from dnSpy and the process is suspended, the only loaded module is mscorlib.dll. My question is, how do I exist the suspend state on UnityDoorstop from dnSpy ? For the debugger the process is already in a running state.. so even if I pause and start it will continue to be suspended.

Doorstop and a bizarre crash

Doorstop Version: 3.3.0.0
Game: Valheim (With unstripped unity files)

I am making a server mod for a few friends of mine, and for one of my friends the game just immediately crashes upon launch.

Originally i was thinking it was something with my mod, so i ended up building different versions of my loader dll targeting different versions of .NET. Nothing has worked so far and honestly I'm stumped. If i manually patch the files with dnSpy the game loads just fine with the mod.

Other things I've had them try before coming here.

• Install and reinstall .NET Framework 4
• Disable Windows Defender
• Disable UAC
• Checking file permissions
• Running steam and Valheim as admin

========== END OF STACKTRACE ===========

x86 version.dll doesn`t contain export address table. (Releases v2.8.0.0)

As the title says, and another mistake which is --doorstop-enabled in the wiki but it is --doorstop-enable in the code.

Debugging the assembly loaded by Doorstop

Is there a way to debug the assembly being loaded and executed by Doorstop 4? I have a game built with Unity 2021.3.2f1. I'm able to attach to and debug the game's assembly with dnSpy, though both dnSpy and Visual Studio fails to debug the assembly loaded by Doorstop because the symbols are not loaded.

Now that I know the game's assembly is obfuscated with ConfuserEx, though it is mainly string obfuscation, method renaming, and debugger detection. Even if it contains anti-debug, it should still be possible for me to debug since my assembly runs before Unity loads.

Doorstop still doesnt work on first launch

version: v4.0.0 release
platform: Windows
game: BattleTech
distribution: Steam

Issue;
Doorstop uses ENV variables to keep track if it already ran, but dynamically set ENV variables are copied by steam during a restart of the games process.

Steps to reproduce:

• make sure steam is not running
• launch BATTLETECH directly via BattleTech.exe (have steam not running)
• steam code detects that it needs to restart, that happens apparently after doorstop already ran
• the game restarts with env variables set from the previous run, that includes env variables set dynamically by doorstop
• thus doorstop thinks it doesnt need to run anymore

Workarounds not working:

• ignore_disable_switch does not work, because the ENV variable DOORSTOP_INITIALIZED is set too, and that leads to skipping of calling the entrypoint
• using a steam_appid.txt file so steam does not restart the game, however steamworks is broken and the game does not work properly (NRE etc..)
• Always use the steam launcher: There are wrappers / launchers that ignore that and run the exe directly, and users who run the exe directly too.

Fix ideas?

• Clear all dynamically set doorstop env variables if doorstop detects that it is in a new unmodified process, leading to doorstop to run again.

Reference for RogueTech Discord: #rogueticket-7596

Logs when using the ignore_disable_switch workaround:
log before restart
log after restart

Does it support unity 2020?

It seems unity 2020 x64 executable does not depend on winhttp.dll. Is it supported?

Would it be possible to use this to override the behaviour of the Unity editor (not for games built in Unity)?

I am trying to build something that needs to load before the Unity editor starts importing assets on launching a project. The gist is that I want to intercept any file system API calls which the Unity editor makes and capture some information when it does. I could override the calls to the file system API via reflection, but the editor does not seem to way to hook into the editor launch pipeline.

Unity does have an [InitializeOnLoad] functionality, but that only starts executing after the asset database refresh completes, so it does not work for my use case. I am wondering if I could use this to run code before the editor starts importing the project.

valheim linux dedicated server (valheim+ mod) - unable to stop server via ctrl+c/sigint

Hi,

I'm opening this issue on both doorstop and BepInEx as I'm not sure on which of these the actual problem is.
The regular Valheim server can be stopped via ctrl+c or by sending a sigint to the PID.
After installing the Valheim+ mod, which contains BepInEx and Doorstop, the server starts as usual but neither control+c on the console or sending a sigint works to gracefully stop the server.
Killing the server via sigterm/sigkill can leave the world data corrupted.

Let me know if you need any additional data, I'm happy to help where possible.

UnityDoorstop doesn't load when doorstop_config.ini is written in UTF-8 with BOM

Hi there,

Using C# targeting .NET 4.0 and 4.5 (tested separately), I used File.WriteAllText to write changes to my doorstop_config.ini.

With the following code, this writes as UTF-8 with BOM:

File.WriteAllText(path, contents, Encoding.UTF8);

And this broke UnityDoorstop. It just wouldn't load.

Changing the file write to UTF-8 without BOM (explicit) fixed it:

File.WriteAllText(path, contents, new UTF8Encoding(false));

UnityDoorstop 4.0.0-rc.7 not working on mac

Hello,

I'm trying to get UnityDoorstop 4 working on MacOS
Mac version: macOS Catalina 10.15.5
Zip: doorstop_macos_release_4.0.0-rc.7.zip
executable_name="Game.app"
target_assembly="Doorstop.dll"

Tried the entrypoint example to write file on .NET 5 with .netstandard 2.1 & .NET 6.
Works on Windows 11.

Error real mac:
dyld: could not load inserted library 'libdoorstop.dylib' because image not found
Error vm mac:
dyld: could not load inserted library ' ' because image not found

Result of echo "${doorstop_name}": libdoorstop.dylib

I'm not experienced with .sh files the only thing I was able to find is that the game is able to start by changing
export DYLD_INSERT_LIBRARIES="${doorstop_name}:${DYLD_INSERT_LIBRARIES}"
to:
export DYLD_INSERT_LIBRARIES="${doorstop_name}"

But it won't trigger the entrypoint or Mac can't write files with that script for some reason?

Suggestion: a signal/callback for when the game is loaded

Hi,

awesome project and a lifesaver. However, I needed to patch the game as soon as Assembly-CSharp.dll is loaded but before any of its code is called. I have a sort of ugly workaround and made a custom Doorstop.dll project for it: https://github.com/pardeike/Rimworld-Doorstop. It would be nice to have a second entry that is called as soon as the games code is loaded so I can refer and use its types in my doorstop project.

Cheers

Can't build "memcpy already defined"

I'm trying to build the solution with Visual Studio 2019, I receive the following error :

libvcruntime.lib(memcpy.obj) : error LNK2005: memcpy already defined in crt.obj
C:...\UnityDoorstop\Proxy\bin\x64\Debug\proxy.dll : fatal error LNK1169: one or more multiply defined symbols found

I can't figure out what is the issue, must be related to this in crt.h

extern void *memcpy(void *dst, const void *src, size_t n);
#pragma intrinsic(memcpy)

[question] Using self-compiled v4 Doorstop

Hey all, apologies for the noob question.

I'm trying to inject some basic code into the Unity game SkaterXL.

When I build the Doorstop project, I get build/windows/x86/release/doorstop.dll file. I renamed this file to winhttp.dll and copied it into the same directory as the game's executable, along with a doorstop_config.ini that looks like so:

# General options for Unity Doorstop
[General]
# Enable Doorstop?
enabled=true
# Path to the assembly to load and execute
# NOTE: The entrypoint must be of format `static void Doorstop.Entrypoint.Start()`
target_assembly=TestMod1.dll
# If true, Unity's output log is redirected to <current folder>\output_log.txt
redirect_output_log=false

TestMod1.dll is a compiled .NET 4.0 Project that contains the following code:

using System.IO;

namespace Doorstop
{
    class Entrypoint
    {
        public static void Start()
        {
            File.WriteAllText("doorstop_hello.log", "Hello from Unity!");
        }
    }
}

However, when I run SkaterXL.exe, I never get an outputted doorstop_hello.log file.

Is there anything apparent that's wrong about my setup here? I'm not positive where I'm going wrong. Any help would be appreciated. Thanks!

Doorstop 4 debugger does not work on Bug Fables, but it works after upgrading Mono to MonoBleedingEdge

This one is half a bug and half a question because I have a good suspicion of what is happening, but I would still like to have more clarifications if that is the case. Basically, I tried to debug the game assemblies without changing any runtime files using Doorstop 4 and the best I got was the game would invoke the crash handler as soon as I try to connect and the connection closes. I have not been able to maintain a connection until I used Unity's files to upgrade the runtime of the game to the newer one this version of Unity ships with which allowed me to debug seamlessly.

Bug Fables (steamdb: https://steamdb.info/app/1082710/ ) ships with Unity 2018.4.12f1 which means it should support the debugging feature the new Doorstop 4 advertise as the readme says it should work past Unity 2017. However, this game has an interesting quirk: it does not actually uses the new Mono (called MonoBleedingEdge) because the game was originally developed for Unity 5.5.4 which only offered the older .net 3.5 compatible Mono 2.x. The only reason the engine was upgraded was to add support for consoles, but due to the fear of anything breaking, Moonsprout Games decided to not upgrade to the new runtime despite the old one being deprecated in that version.

This has proven to be very difficult for me to deal with because after a bunch of tests and research, I found that the only way for me to debug the game assemblies while preserving the runtime is to either use a Windows vm (I primarily use Linux) to generate full pdb files (not protable ones) from recompiled sources JUST to convert them to mdb or to use the Unity's original tooling. The later in particular have not been working as well as simply using the Unity files to upgrade the game to MonoBleedingEdge which is not only more stable, but also more compatible. FYI, the reason I use recompiled sources over dnSpyEx is due to it being very inefficient to decompile large functions which this game has.

The reason I am bringing this up is because I am both reporting it as a bug and also wants clarifications on the matter. Does Doorstop 4 supports the older Mono Unity shipped with despite the fact the game is a version above 2017? If the answer is no, I might as well ask in general: am I better off to upgrade the runtime even if it risks altering the behavior of the game?

Doorstop on Linux logging to .config/mimeapps.list

Using Unix version of BepInEx 5 on Rhythm Doctor.

Whenever I launch Rhythm Doctor, doorstop seems to be logging to my .config/mimeapps.list file and it breaks all my default application handling! It adds the line Found UnityPlayer, hooking into it instead to the start of the file so my system can't parse the file.
It also makes a folder in the game directory called Found UnityPlayer, hooking into it instead in the game folder, with this file, minus the .txt extension.
profilerc.txt

It seems to be some error with how doorstop is trying to capture/redirect stdout, but for now I've compiled doorstop without logging to fix it.

Windows 11 issues

Unable to run on windows 11. No errors just goes into an infinite crash like there is some policy preventing doorstop from injecting the code.. Not sure how to resolve.. Any Assistance would be much appreciated.

[question] about ignoreDisableSwitch

Hello,

First of all, I am totally new to modding unity games and also to doorstop, just found about it a few days ago when checking out bepinex.

I would like to ask where I can get more information about ignoreDisableSwitch. Checking the config file and the DOORSTOP_DISABLE documentation I understand that this config would ignore an env var that disables Doorstop.

But I have some questions:

1. Why would I want to specifically disable it via an environment var? is there a known use case?
2. What are the risks of enabling ignoreDisableSwitch? as there is an alert that suggests it has some risks

I recently had an issue where a steam game was restarting just after it launched and disabling bepinex, changing this config in doorstop to true made it work, but I am clueless about why would I want it as false, or if there is a risk around using it as true.

Thanks in advance

Doorstop segmentation fault with Rust (Linux)

Hi I've tried to make Doorstop work with Rust (ds), on Windows all works but on Linux I always get a segmentation fault.
Host system is a Debian 11, I'm using the supplied start script with Doorstop for Linux.
The game uses engine version 2019.4.7f1 (e992b1a16e65).
Any help would be appreciated, thanks.

Hooks fail to run under RenderDoc/apitrace

When a game, Muck in this case, is run through RenderDoc or apitrace, doorstop's hooks fail to activate.
I confirmed that winhttp.dll loads in the game's process, but no environment variables from doorstop are created.
I built x64 VerboseRelease 3.4.1.0 and the resulting log is the same as a normal run except it just ends at "Hook installed!!", instead of continuing on with "Got mono_jit_init_version at XX" and so forth.

I can't get DoorStop to work on My Summer Car in Wine/Proton

So it does work under Windows, but on Linux and MacOS under Wine/Proton it completely fails to load. Any chance you can give me some guidance here?

UnityDoorstop can't work!

I find that UnityDoorstop can't work in sometime.
But I don't know why.
(This problem maybe cause as some optimization

My friend also has this problem.

I test the Example "Doorstop.dll". It's can't work too.
So I consider that it is the problem of UnityDoorstop.
