A Merry Monumental Multiplayer Moment!

**Vrosivs Avgvstvs Rakvs** · April 03, 2018, 05:35 PM

Greetings everyone! We just had a groundbreaking thing happen! After much trial and error and a fair amount of frustration we made RTR8 multiplayer work! It was a wild ride, and after many stressful moments we figured out the very specific failsafe way of making it work. And the result was the first ever RTR8 multiplayer battle – a small one but a very significant one as well! We’ll be posting more info on multiplayer when we release the next RTR8 version, v4.0. Oh, by the way, the release date for RTR8 4.0 is April 29^th

Here’s some screenshots

are you using phalanxman's stat system? losses (even on the winner's side) seem pretty high

We are not.

Yes well done. I remember back in 2007 when I managed something similar. I don't recall if it was RTR or RS.

It did involve a number of attempts and a few pints of Japanese beer (I was staying in in the Honda owned hotel in Swindon while I was working on a nearby client site).

Thank you, everyone!

I completely understand the beer part, haha

We tried to make it work a year ago, too, but it all flopped for a reason not entirely known to us, as the checksum was behaving seemingly random and wild. We picked it up again a few days ago and experimented and brainstormed a fair amount, and BHL 20 had an idea that just might work and it did. The damn map.rwm file was messing with the game's checksum just enough for it to show a mismatch although apparently everything was at it should be and the versions we had running were identical to the last file. Even our map.rwm files were completely identical yet still the checksum didn't want to behave. One of the prerequisites for making mod multiplayer possible, as we found out, is to ALWAYS erase the map.rwm file before AND after attempting to play multiplayer battles. We will release an in-depth guide and explanation once we release at the end of the month. We will also be setting up a discord server for the community to meet and play

And, of course, both the base game's checksum and the mod's checksum has to match for all the players, so even the slightest modifications to the vanilla files can render the mod multiplayer unplayable, apparently. Luckily, the checksum doesn't take into account the saves and preferences folders, as the experiments seemingly show; and the launch commands can differ, too, though this should be straightforward, we did try virtually everything. The first time ahowl11 and I ran the same launch commands, the second time I added a few and it ran fine again. It was a wild ride, haha.
But I digress. More on all this at the end of the month, we want to make sure about everything regarding this.
