The Inspector is used to view and edit the properties and settings of Game Objects, Assets, and other preferences and settings in the Editor.
When you select a GameObject in the Hierarchy or Scene View, the Inspector will show the Properties of all Components and Materials on that object and allow you to edit them. The image above shows the inspector with the default 3D camera GameObject selected. In addition to the object’s position, rotation and scale values, all the properties of the camera are available to edit.
