Crash on Unreal Engine 4.19 #8

Closed NuLL3rr0r closed 6 years ago

NuLL3rr0r commented 6 years ago

We are using the latest GitHub code on 4.19 branch (at the moment preview 6) and it works fine for us with all the plugins working. But only adding ImGui plugin to the Plugins folder will crash our game upon hitting the play button on both Windows and Linux.

Here is the call stack and crash log and the failed assert from engine code: https://pastebin.com/xRvTsGGS

Hey, I’ve just tried to build it with 4.19 (preview 6) and I don’t have any problems - I tried Windows but you mentioned equal problems on Windows and Linux.

I’m not exactly sure what is the exact problem that you have, but I checked the link that you provided and I don’t see anything in that call stack that would point to ImGui. It crashes during Slate widget paint, so I would expect to see a SImGuiWidget somewhere in that list, but I don’t.

However, you have a few messages about libUE4Editor-ImGui-Linux-DebugGame.so being “missing or built with a different engine version”.

NuLL3rr0r commented 6 years ago

OK, thank you! Then I'll try to reproduce the issue with a new empty project to see if it crashes. We have RTTI and Exceptions enabled in our project and many more settings and libraries integrated into our project. In my estimation, I should spend some quality time and test things one step at the time, to see if it happens because of UnrealImGui or not. It may take some time. But, I'll report back.

I tracked down part of the issue and it was due to FMOD plugin and the way it had to be initialized in our project in order to make it work in a packaged game. I removed FMOD from our project and re-added UnrealImGui to see if it works.

Here is how we load UnrealImGui in our Build.cs:

    public void LoadImGuiPlugin(ReadOnlyTargetRules Target)
    {
        String basePath = Path.Combine(this.PluginsPath, "ImGui");
        String imGuiPrivatePath = Path.Combine(basePath, "Source", "ImGui", "Private");
        String imGuiPublicPath = Path.Combine(basePath, "Source", "ImGui", "Public");

        this.PublicDependencyModuleNames.Add("ImGui");

        this.PrivateIncludePaths.AddRange(
           new string[] {
               imGuiPrivatePath
           });

        this.PublicIncludePaths.AddRange(
           new string[] {
               imGuiPublicPath
           });

        Console.WriteLine(String.Format("ImGui base path: {0}",
                                        basePath));
        Console.WriteLine(String.Format("ImGui private path: {0}",
                                        imGuiPrivatePath));
        Console.WriteLine(String.Format("ImGui public path: {0}",
                                        imGuiPublicPath));
    }

Here is the crash log from when I hit the play button in PIE mode:

I just added UnrealImGui using the C# function in the build system. No C++ code yet and it crashes. Obviously, removing UnrealImGui fixes the issue for us.

Hi, I'm a bit confused. Is this a crash in FMOD then? I see some FMOD logs and nothing related to ImGui, so it is hard for me to tell how it is connected with your problem.

However, there is one thing in your Build.cs file that seems suspicious to me. Why do you need to include ImGui paths? Public paths ("ImGui/Public" and "ThirdParty/ImGuiLibrary/Include") are already added to the ImGui module’s public include paths and should be automatically included in all modules that depend on it. Private paths should be not needed outside of the ImGui module.

There is some information in ‘How to use it’ section, but in short the only line that really needs to be added to Build.cs file is this: PrivateDependencyModuleNames.Add("ImGui");

Does removing part where you include paths, solve your problem?

Thanks for the response. Well, I totally disabled FMOD initialization that caused the original crash in our game (though I wasn't able to remove FMOD from our project since there is code that relies on it). Those FMOD logs are related to the master bank of the FMOD asset and I believe they are not indicating any errors.

Regarding Build.cs file. Well, I did load all our plugins using the same method. So, I used the same approach for UnrealImGui. But, I'll try your suggestion and report back.

Thank you!

Thanks. I was just confused that FMOD logs are still there.

Coming back to ImGui. Since I cannot reproduce that crash myself and I don't see anything that would explicitly pointing to ImGui module, it is hard for me to speculate. However, since this seems to be connected with Slate RHI resource management it would be good to check whether ImGui module is not doing anything stupid.

So, if using suggestion from the post above doesn't help I would suggest removing implementations from FImGuiModule::StartupModule() and FImGuiModule::ShutdownModule() functions in ImGui/Private/ImGuiModule.cpp. Once you do that ImGui plugin should stay as inactive as possible - it won't create module manager and therefore should never create any resources nor widgets. There will be still a few cvars (but those shouldn’t be a problem) and whatever is created by Dear ImGui implementation. If that will stop the crash, then I can try to defer textures loading in FImGuiModuleManager.

One more thing, just to make sure. I suppose that the loading phase is left to be PreDefault, isn't it? And that the module is not loaded explicitly by the game code (but since you said that there is no C++ code then I assume that this is true).

I couldn't reproduce this in neither 4.19 (Preview 6), 4.19.0 nor 4.19.2. So, whatever this is I think it must be something different than the engine version alone. I'm labeling this issue as an invalid one, to avoid confusion.

However, I'm interested whether this thread can be closed and whether you had a chance to test what we discussed above and/or still have this problem?

NuLL3rr0r commented 6 years ago

Sorry, I've been very busy with AI in our game and postponed the UI for now. So, I was not able to track down the issue. But, I'll try to run another test to see if it still exists.

NuLL3rr0r commented 6 years ago

OK, I cloned the master branch again and put it in our Plugins directory. Then I did load and enabled it using LoadImGuiPlugin I've mentioned before. The editor and game started successfully. I tried ImGui.ShowDemo and ImGui.InputEnabled console commands and viola it worked.

It was definitely an issue on our side. We spent sometime stabilizing our source code during the last few weeks and it seemed to automagically fixed the issue for us.

Thank you so much for your time!

Thanks. I'm happy that it works for you.
