Play animation on object in 4.3

Previously, I could access and object by saying object.animation.Play() but now after upgrading and creating an animation there is an ‘Animator’ in the inspector, not ‘animation’

So far I have only found out this alternative: Playing an Animation that is within a GameObject - Questions & Answers - Unity Discussions

But that seems like a hack. How do I do this properly?

Bump++ any help ? cant even animate the camera in unity4.3
