Which Unity tool is used to manage the flow of animations over time?

The Animator Window is the primary tool in Unity for managing the flow of animations over time. It provides a visual interface where artists can create, visualize, and fine-tune animation sequences. Inside this window, you can arrange different animations, control the transitions between them, and set parameters that dictate when certain animations play or how they blend together. It allows for a more dynamic approach to animation, enabling the animator to visualize how an object will move throughout a scene and to easily adjust timing and sequences to get the desired performance.

The other options serve different functions within Unity. The Animation Curve is a tool used to interpolate values over time, but it doesn't manage the animation states or transitions as a whole. The Scene View is primarily for laying out and visualizing the game world rather than managing animations directly. The Inspector Panel is useful for adjusting properties of game objects but doesn't specifically focus on the flow of animations over time like the Animator Window does. Hence, the Animator Window stands out as the correct choice for managing animations within Unity.
