Not wasted, never wasted. You went through two tutorials, now apply that knowledge and experiment with the software a bit. Download the new version of unity and try to reimplement what you covered, try from memory and then use a different reference than the tutorial if you cannot; look for the official docs and built-in support, try googling for the problem and finding an answer on stackexchange, try asking on a IRC channel and build up a friendship there. That time was not wasted my friend, yes the code may be obsolete but you're more likely to understand the design choices of the new unity now you've seen the old one.
Thanks. I like your online presence, you're always so congenial, constructive and supportive, in any thread I've seen you in. I think I'm gonna stop trying to learn Unity3d for now, and focus on Blender instead (which is more difficult to learn; I can't understand why, as usually I pick up software very quickly). Due to realizing, in the past, I've always done much better at the design and art side of things rather than coding.
