Tell us about yourself!
It's strange that even though this instructable is over 8 months old, no one has pointed out that your code doesn't work. Your two GetComponent calls do not call anything. The second GetComponent is supposed to be GetComponent<charactercontroller>() but I can't figure out what the first GetComponent is supposed to be getting. I think the problem is the website may be stripping out whatever is between the <> characters. The code as-is just generates compiler errors in Unity 5 and doesn't do anything. It's a shame because the rest of the instructions are pretty solid and if the code worked it would be a really great primer on 2.5D in Unity.
