I have two application. One is written in C# and runs on my laptop (the client), and the other is written in c++ (it's an Unreal Engine 4 application) and runs on an Amazon Web Services instance (the server).
I have written both applications and thus have full control of them.
I'd like to direct user input on the client device to the application running on the server (UE4 application). I could obviously record user input events on the client, serialize them as JSON, transmit over the network, deserialize and map to what ever function I want within the UE4 application, but that is really cumbersome and in no way ideal, since UE4 already has built-in input event listeners...
Essentially, I want to control the UE4 application (running on the server) as if it were running locally (on my laptop, the client).
Does anyone here know how I can direct keyboard & mouse events from the client to the server application?
I solved this by writing an application that runs on the client and listens for the key down event. That key down event is then sent over the network via UDP to another application which runs on the server (as does my UE4 application). I then used the method described here to pass the incoming message to the target application which in my case, is UE4.
