What does the Hierarchy window display in Unity?

The Hierarchy window in Unity is essential for displaying the structure of the GameObjects that are present in the current scene. This organization allows artists and developers to see how GameObjects are nested and related to one another, making it easier to manage complex scenes. Each GameObject can be dragged and dropped into different positions within this hierarchy, enabling the rearrangement of the scene's structure easily.

While visual properties of GameObjects are relevant and can be adjusted in the Inspector window, they are not shown in the Hierarchy. Similarly, game physics settings are typically maintained within the project's physics settings and related components of GameObjects rather than the Hierarchy. Also, user interface elements for the game, such as buttons and text, would appear as GameObjects in the hierarchy but are not exclusively what the Hierarchy displays. This comprehensive view of GameObjects and their relationships is pivotal for efficient scene management and development in Unity.
