There are a few key elements of this recipe:

• Animation Curves: You can add curves to your animations (multiple curves per animation clip) in the Import Settings, Animation tab. Curves assign arbitrary float values to the animation frames. If the name of the curve is the same as the name of a parameter in the Animator Controller, the value of the parameter will be set to the value of the curve in any given frame of the animation.
• Using curve values: We are using the ToIdle value set by the Animation Curves in the WalkForward, WalkLeft, and WalkRight animations to trigger the transition from Steering to Idle (when the ToIdle value is less than 0.5) or from Steering to ToIdle animation (when the ToIdle parameter is greater than 0.5). This allows us to control the state transitions in the Animator Controller depending on the poses in the animations.
