In Unity, which tool allows for manipulating an object's position, rotation, and scale?

The Transform Tool in Unity is specifically designed for manipulating an object's position, rotation, and scale within the Scene View. This tool provides three distinct modes, each corresponding to one of the three transformations: moving (position), rotating (rotation), and scaling (scale). By selecting an object and using the Transform Tool, users can easily adjust the object's parameters directly in the 3D environment, making it intuitive for artists and developers to position their objects precisely where needed in the scene.

In contrast, the Inspector is used to view and edit the properties of selected GameObjects, but it does not provide direct interaction in the 3D space for transformation. The Scene View is the visual environment where objects are placed, but it does not inherently provide the tools necessary for manipulation. The Hierarchy shows the organization of all GameObjects in the scene, allowing for selection and structure navigation but does not offer manipulation features on its own. Thus, the Transform Tool is essential for adjusting an object's position, rotation, and scale effectively.
