Multiplayer 2.0 - Unreal Engine - full source code ?

I downloaded nuget package for C++ GSDK, but it doesn't seem to contain any source code beyond header.

That makes it quite hard to integrate with unreal custom builds, since unreal comes with it's own ssl, crypto and curl libraries which might be different than GSDK.

Would it be possible to provide source code library ? If it cloud be header only, it would be even better :).

I know this is not what you're looking for, it is the source code for a multiplayer server in Unity but maybe it will help.

I actually just ran through this. Here's my solution, hope it helps:

Unpack the nuget package into a ThirdParty folder in my project folder. This gives you access to the .dll and .lib files, as well as the gsdk.h header. You can use an app from the Windows Store for this.

In my .Build.cs file, I added:

if (Target.bWithServerCode) {
  bEnableExceptions = true;



You don't need the if, but since my client will be android, I want to avoid including or linking the GSDK on client code. Now you can use the GSDK in your server code:

  #include "gsdk.h"

void UMatchRoyaleGameInstance::Init() {

	try {
		Microsoft::Azure::Gaming::GSDK::registerHealthCallback([] { return true; });
	} catch (Microsoft::Azure::Gaming::GSDKInitializationException& e) {
		UE_LOG(LogTemp, Error, TEXT("GSDK Initialization failed: %s"), *FString(UTF8_TO_TCHAR(e.what())));

This will fail at runtime, unless you copy the files from ThirdParty\GSDK\lib\Windows\x64\Release\dynamic into your Binaries folder in your project path. When you package your game, you need to also copy the files next to your packaged binary. More info here.

Thanks for helping out! In addition, we do eventually plan to add in the GSDK functionality to our core SDK, which would make it a bit easier to pull into UE4. I don't have a timeline to share right now, but it's definitely something we've looked at.

I did all the steps above, and got the Playfab GSDK integration work on the local Plafab Environment (PlayFabVmAgent). It works absolutely fine, I can connect clients to . but when I deploy the same on Playfab server, I get the Server IP and port but somehow it dose not connect I have spent two days in just figuring out but still not clue.

Sorry for the delay! You might want to spin up a new thread to discuss this, as I don't think it's exactly related. In the meantime, there are a couple of things to check:

1. When you run the server locally, are you running inside the container?

2. What does status does the server instance report as in Game Manager?

When you do create a new thread, please include your title id so we can have a look.
