The animator controller isn't letting me do anything

Basically it isn’t letting me add animations to the animator or add it to a character even when in the script attached to the character has a public variable for the animator, whats going on???

Right-click in the Animator window and select New State.

Select the new state and click the “Motion” field in the inspector to select a motion clip.

Animat!OR! = Mecanim , Animat!ION! = Legacy Animations.

What you are probably aiming for is the legacy system, where you need the Animation Component.
