Hello, i’m working on a multiplayer project and i wanted to implement Raknet features (especially Nat punchthrough) in my project.
I have found this plugin on git hub : GitHub - yujen/RN4UE4: RakNet plugin for Unreal Engine 4.
I have installed it but i don’t know how to use it? I thought that plugins were blueprint callable but I didn’t find how to activate Nat punchthrough in Blueprints.
Does someone know more about this plugin?
Hi tueurdudimanche:
I have create a sample project, but only Ping server/client in the project currently.

You can find usage in Ping.h/Ping.cpp
If I have free time, I will port RakNet’s NAT punchthrough sample 
Hello Yujen! Thank you for your answer, did you port NAT punchthrough sample? I don’t know how to port it into UE4 
I’ve also have a problem when i try to open your project example. It tells me :
"Running C:/Program Files/Epic Games/4.9/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project=“C:/Users/Nicolas/Desktop/RN4UE4_Sample-master (1)/RN4UE4_Sample-master/RN4UE4_Sample.uproject” -game -rocket -progress
Discovering modules, targets and source code for game…
ERROR: Couldn’t find module rules file for module ‘RakNet’.

I’ve also have a problem when i try to open your project example.
Hi nico77950,
The RN4UE4_Sample doesn’t contain RakNet plugin,
you can pull the source code from https://github.com/yujen/RN4UE4 to project Plugin folder.
In your case is “C:/Users/Nicolas/Desktop/RN4UE4_Sample-master/Plugin/”
did you port NAT punchthrough sample?
Currently I don’t port NAT punchthrough yet. Perhaps you want to try yourself.
You can find the sample from official repo NATCompleteClient and NATCompleteServer
May this post can help you.
