The Scene View is your interactive sandbox. You will use the Scene View to select and position environments, the player, the camera, enemies, and all other GameObjects. Maneuvering and manipulating objects within the Scene View are some of the most important functions in Unity, so it’s important to be able to do them quickly. To this end, Unity provides keystrokes for the most common operations.
See Scene View Navigation for full details on navigating the scene view. Here’s a brief overview of the essentials:
You might also find use in the Hand Tool (shortcut: Q), especially if you are using a one-button mouse. With the Hand tool selected:
Click-drag to drag the camera around.
Hold Alt and click-drag to orbit the camera around the current pivot point.
Hold Alt and right click-drag to zoom the Scene View. On Mac you can also hold Control and click-drag instead.
In the upper-right corner of the Scene View is the Scene Gizmo. This displays the Scene Camera’s current orientation, and allows you to quickly modify the viewing angle.
Each of the coloured “arms” of the gizmo represents a geometric axis. You can click on any of the arms to set the camera to an orthographic (i.e. perspective-free) view looking along the corresponding axis. You can click on the text underneath the gizmo to switch between the normal perspective view and an isometric view. While in isometric mode, you can right-click drag to orbit, and Alt + middle-click drag to pan.
Note that the Scene Gizmo will be hidden when the view is in 2D mode, since the view is always directly at the XY plane.
See Positioning Game Objects for full details on positioning GameObjects in the scene. Here’s a brief overview of the essentials:
When building your games, you’ll place lots of different objects in your game world. To do this use the Transform Tools in the Toolbar to Translate, Rotate, and Scale individual GameObjects. Each has a corresponding Gizmo that appears around the selected GameObject in the Scene View. You can use the mouse and manipulate any Gizmo axis to alter the Transform Component of the GameObject, or you can type values directly into the number fields of the Transform Component in the Inspector.
The Rect Tool can be found in the Toolbar next to the Transform tools and allows you to view and edit the Rect handles on 2D and 3D objects.
For 2D objects (sprites) you can hold down shift to scale uniformly. If you scale non-uniformly along axis that don’t match the local axes for the object, it will be scaled along the closest axes it can. For 3D objects you can now also use rect handles; Rect handles are shown for different planes depending on what angle the object is viewed from.
The control bar lets you choose various options for the scene view. You can switch on or off the audio, lighting and 2D mode and also control how objects, image effects and gizmos will be displayed. See the View Modes section for further details.
