Ok, what I'm trying to do is to create a mobile companion app that I can use as a controller for the PC Game.
I already have this working within UE4 (a build for the PC server and a build for the mobile apps), but the mobile app is 60 mb without any content at all, so I'm looking to replace it with something much more lightweight.
What I would basically need is to send control commands from the mobile app (movement axis, turn, jump...etc), which would then be interpreted inside UE4. Also I would need UE4 to send feedback events to the mobile app (like player killed), so C3 will interpret them and will display a splash screen saying you got killed, for example.
I already found a few plugins for UE4 that will allow me to create a server through UDP (which is what I have been told is the best solution for my problem), but I still need to find a client solution for UDP.
Thanks.
Ps: I ONLY need this to work in LAN.
