Anyone know much about the Animator Editor?

I’ve got an issue in 2.6 that is pretty critical to getting my game done, but it seems like nobody around knows anything about the animation editor:

Failing help with that - anyone got any suggestions for how I should author movement patterns for my side-scrolling shmup?

Why are you using 2.6 ? You’re a new member both here and on unity answers, why not use the newest version of the software ?

The main project I’m working on is using Unity 2.6 as performance isn’t good enough under 3 yet. I don’t want to have multiple versions of Unity knocking around so I’m sticking with the lowest common denominator.
