Yes, UNITY is limiting in the extreme! I now get that. Perhaps the choice to use the FREE "Personal Unity Game Engine" may not have been such a wise choice.
I have developed on multiple platforms and you take the strengths, not the least common denominator, of each platform when you develop and application. Then you port it to another platform and work through the issues of implementing the same or very similar functionality. These all in one development tools usually are limited to the least common denominator between all OS and that usually means slightly better than single active window DOS functionality. Yeah, I will take a very long break from EDCE. It is nowhere ready for prime time. I want fluid, fast flowing fully featured games and this is not even close to it, yet. Why does it use 37% of all processors just sitting IDLE???? (for instance, just the opening screen but everything is 37% or much more processor utilization (all processors) no matter what the game is or is not doing)
