I've had a look inside the "LastStandSetup.lua" found in the SteamApps/lua folders. I noted that essentially, the Last Stand and subsequent Challenges, are in fact written as if by the way of a modder- that is to say, everything in there is handled from event handlers. Neat. I've took it upon myself (after being unable to find anything on the forum under User Interfaces), to have a shot at achieving the following: STEP 1: Create a button that slots in alongside the initial game UI. Like so: STEP 2: Once the button is clicked, execute the code to join the server's I.P Address. And thats it! basically! I haven't looked at any of the multiplayer code, but I've been diving into the UI stuff, would I be right in assuming it is not without the realm of possibility to use the following event: OnPostUIDraw To create some kind of button to achieve this? Watch this thread for more progress as it happens-
