hierarchy and toolbar in unity3d



The Hierarchy contains every GameObject in the current Scene. Some of these are direct instances of asset files like 3D models, and others are instances of Prefabs, custom objects that will make up much of your game. You can select objects in the Hierarchy and drag one object onto another to make use of Parenting (see below). As objects are added and removed in the scene, they will appear and disappear from the Hierarchy as well.


Unity uses a concept called Parenting. To make any GameObject the child of another, drag the desired child onto the desired parent in the Hierarchy. A child will inherit the movement and rotation of its parent. You can use a parent object’s foldout arrow to show or hide its children as necessary.

The Scene View in unity3d:

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.

Scene View Navigation

See Scene View Navigation for full details on navigating the scene view. Here’s a brief overview of the essentials:

  • Hold the right mouse button to enter Flythrough mode. This turns your mouse and WASD keys (plus Q and E for up and down) into quick first-person view navigation.
  • Select any GameObject and press the F key. This will center the Scene View and pivot point on the selection.
  • Use the arrow keys to move around on the X/Z plane.
  • Hold Alt and click-drag to orbit the camera around the current pivot point.
  • Hold Alt and middle click-drag to drag the Scene View camera around.
  • Hold Alt and right click-drag to zoom the Scene View. This is the same as scrolling with your mouse wheel.
