UDK Multiplayer Issue: Can't connect to server on own computer

This was an annoying issue that I couldn't solve last time, I was trying to run 2 instances of UDK on my own machine for easier multiplayer testing, and I couldn't connect. I was following this:

and getting this when I tried to join using "connect 127.0.0.1"

Log: Pending connect to '127.0.0.1/UDKFrontEndMap?Name=Player?Team=255' failed; Duplicate UID

I'm running with steam subsystem enabled (which is currently the default) and as a result I wondered if this had anything to do with it, after a google around I found that steam does indeed do an authentication check, which fails when I'm connecting to myself (hence the duplicate UID message).

To fix this find the UDKGame.ini and change the following values to false:

[Engine.AccessControl]
bAuthenticateClients=True
bAuthenticateServer=True
bAuthenticateListenHost=True

This should clear it right up ^_^

One foot in the wagon 2 : Back in the habit

In the last few months I started working for reals ! I'm not a proper ickle software developer ^_^ Shame the project I'm currently working on is soul sucking >.<

To keep my loss-of-soul to a minimum I've been writing a Windows / WinPhone 7 game all about Math !



This has kept me busy but I've started to get an itch for the UDK again. I've decided to split my time 80/20 between my Math game and continuing to learn the UDK. Yesterday I downloaded the latest UDK and started having a tinker again. I remembered more than I expected and still have my old projects incase I've forgotten anything.

First step will be to go over all the stuff I could do before, here's to something resembling progress !
