Networking in UE4

Here are a few things I’ve found:

https://wiki.unrealengine.com/Networking/Replication

https://docs.unrealengine.com/latest/INT/Programming/Gameplay/Framework/Networking/Replication/Implementation/DynamicArrays/index.html

I’m still trying to shake a stick at it, but heres a quote from one of the dev’s

Network documentation is lagging behind unfortunately, but we’re here to answer questions as best as we can.

That being said, launch your game this way in development

UE4Editor.exe <gamename> <mapname>?listen -game

If you are already in the game, use the console and type open <mapname>?listen

and you will see in the logs that it is setting up for a multiplayer game.

Clients then can type

UE4Editor.exe <gamename> <ipaddress> -game

or open <ipaddress> from the console

While we get our documentation in order, please check out http://wiki.beyondunreal.com, which has a great wealth of UE3 information that is still very relevant when it comes to networking. Learning about replication and remote procedure calls (RPCs) will be critical to getting your data back and forth between clients and servers. The syntax may be different, but the concepts are the same.
