[Networking] Mobile-Cross-Platform Multiplayer

Hey guys,

I did a really simple setup for a mobile game with multiplayer support, however I cannot play in the Editor (PIE) and connect to that server using the my phone (I tried with listen server and dedicated server). If I however do the Mobile preview and try to connect via the launched app on my phone (Android), I can join. Is it possible to have a cross-platform game (between iOS and Android) while having a dedicated server running on Windows (or Linux, I don’t really care, at least some sort of dedicated server)? (I’m pretty sure it’s “possible”, but with an non-enormous amount of work to do?)

When trying to connect on a Windows-Server with my Android-Phone, I get this log:

LogNet: NotifyAcceptingConnection: Server AISMap accept
LogNet: Open AISMap 11/15/14 17:50:13 
LogNet: Added client connection.  Remote address = :55172

Thanks in advance!

I’m having the same issue.

UserId Invalid might be the issue, make sure your mobile and PC use same Online Subsystem, also check mobile log, in android you can do that via logcat

Thanks for the info, I’ve got this log:

LogLinker: Can't find file for asset '/Game/Maps/UEDPIE_1_Example_Map' while loading NULL. LogLinker:Warning: Can't find file '/Game/Maps/UEDPIE_1_Example_Map' LogUObjectGlobals:Warning: Failed to load '/Game/Maps/UEDPIE_1_Example_Map': Can't find file '/Game/Maps/UEDPIE_1_Example_Map'

Looks like PIE have mangled the map name (added a prefix ‘UEDPIE_1_’) so client on my phone failed to load the map.

Did you bake it for the specific device

6

Depends on the game and how many players you got playing at once.

Hello, I really like to make an android multiplayer game.

I am not sure what online sub system shall I use? Could you throw some light on it?

Appreciated!

8

Most android games use google or Facebook

9

You could create your own sub system to that’s also Optional

10

I am sorry, I know that using steam, you can copy and paste rows of code to the engine.ini and the sub system work. But for android, how to write these code? I cannot find a sample on the ue4 doc.

Thank you,

Here’s a sample

12

But I don’t think your gonna get the results your expecting especially since the steam subsystem are designed for pc

13

I don’t think the steam subsystem works with android devices

14

You wanna download android developer to get there subsystem

How much c++ coding do you know
