So, I'm thinking that in order to get this thing moving properly, I want to do the main portion of it as a func_rotating_door centered on the center axis, and then parent the individual gondolas to the wheel. However, I'm trying to figure out how to set up the gondolas so that they rotate as well- so that they remain level as they go 'round. I'm thinking that they ought to be func_rotating_doors too, but I stink at math so I can't figure out whether or not they ought to be at the same speed (but opposite direction) or something else. Alternately I was thinking I could do this with some physics objects, but I don't know if that'd get even more complicated. And just to keep this all aboveboard, this is part of a map I'll be working on for Team Interrobang's prophunt map contest.
