This is the link to the
Assembling the campaign.Technical issues. thread.
And he haven't cracked anything relating how FMB works, he just posted some instructions (not full description of it anyway) regarding how a campaign must be made.
Things I've personally already knew, it's enough to have a look at the way MG's IL2 CoD original campaigns are made (and that's how he learned what he posted in there too). That's how I've transformed your missions into a proper IL2 CoD campaign (I just did a fast and dirty work of it, haven't tried to do it in the proper way, as I don't have time for that. A proper implementation of a campaign will need modifications of the mission files, adding screenshots and intermediate descriptions for all missions, and also scripting).
I don't understand what do you mean by what do I think.. If you ask me if I know how to make missions, or a proper campaign, or make C# scripting.. the answer is yes, I do. I am working in real-life as a lead designer/senior producer/project-manager in a game developing company, and I know programming too (I've finished an IT university).
