To be more precise about my issue, if I switch to SM mode, then go to the system view and create a new NPR race (say Russian Alliance) with as specie Human, then it seems I'm auto switched to this race, and they get a colony on the planet body I selected.
But then, it starts to not work as it worked in VB6. I can't switch back and forth between each race (mine and the various human NPR). When I exit and re-enter the system view, I can in fact only access my race.
I clearly remember in VB6 that I could switch from one race to another and add stuff to each of them, as I wanted. It seems it's either no more possible now ?
Untick 'Create as NPR'. If you leave that selected, you don't get to run that race.
What you are describing is running several Player races, even if you think of one of them as yours and the rest as NPRs.
I don't want to run them and I want them to be run by the computer, so they should be NPR race. What I want though, past the initial colony they can have, is to edit their assets and add colonies there and there in the Sol system, like a Russian colony on Mars, a Chinese one on Titan and such like.
This was doable in VB6, even for NPR, if you had access to the 'DB Designer password', which had elevated privileges compared to SM mode. Which I did (having access), you had to PM Steve because he prefered to not make it public. With this password, you could edit a NPR as if it was a player controlled race.
I guess it just means that the tools are not all there for now in C#. And hopefully Steve will still allow this kind of editing further down the road.
