Support for UE5

[DervexDev]

I think it would be nice to have this plugin on Unreal Engine 5. Current version of Chroma SDK won't compile on latest version of engine obviously.

I'll look into that. When I tried the UE5 pre-releases the demos were enormous and the editor was laggy. I'll look into making the new version compatible.

To get the VS 2022 solution to generate make the following changes:

• UE4ChromaSDKRT\UE4ChromaSDKRT.uproject - Modules no longer supports "Type": "Developer"

{
    "FileVersion": 3,
    "EngineAssociation": "5.0",
    "Category": "",
    "Description": "",
    "Modules": [
        {
            "Name": "UE4ChromaSDKRT",
            "Type": "Runtime"
        }
    ]
}

• UE4ChromaSDKRT\Plugins\ChromaSDKPlugin\Source\ChromaSDKPlugin\ChromaSDKPlugin.Build.cs - Definitions changed to PrivateDefinitions and PublicDefinitions

  PrivateDefinitions.Add("CHECK_CHROMA_LIBRARY_SIGNATURE=1");
  PublicDefinitions.Add("CHECK_CHROMA_LIBRARY_SIGNATURE=1");

• Fix error - 'byte': ambiguous symbol - https://developercommunity.visualstudio.com/t/error-c2872-byte-ambiguous-symbol/93889

For this one, I need to enable showIncludes - https://docs.unrealengine.com/5.0/en-US/build-configuration-for-unreal-engine/

• Edit: %appdata%\Unreal Engine\UnrealBuildTool\BuildConfiguration.xml

<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
  <WindowsPlatform>
    <bShowIncludes>true</bShowIncludes>
  </WindowsPlatform>
</Configuration>

And then you can see in the output that rpcndr.h is included by including AllowWindowsPlatformTypes.h.

Although this looks more like a Windows SDK bug.

When UE5 support ?

[MinoDab492]

@tgraupmann You should submit that as a pull request, it would be great to have functional UE5 support without having to do so much work.

[tgraupmann]

I need to port one piece at a time until it all works. I haven't needed to support a shipping title in UE5 yet so I haven't prioritized this over my other tasks yet.

[tgraupmann]

I added extended keyboard and Unicode path support for UE4. The next step is to attempt the UE5 upgrade again. https://github.com/razerofficial/UE4_XDK_SampleApp/tree/SUPPORT_UNICODE

[tgraupmann]

I'll copy the repository to my username until the update works and then I'll post on razerofficial. https://github.com/tgraupmann/UE5_XDK_SampleApp

[tgraupmann]

Okay I have it working. https://github.com/razerofficial/UE5_XDK_SampleApp

The last struggle was std::byte collisions. I ended up just removing using namespace std; and just used std::wstring etc where I needed it. That was a fast fix and now the samples are up and running in UE5.

@tgraupmann added support for UE5 in this separate repo. Thanks!
