  • There are two really nice hotkeys to insert or delete array elements in the inspector. SHIFT + DEL will delete the selected element and CTRL + D will duplicate it. SHIFT is only needed for reference types like GameObject[].
  • If you are dealing with deep hierarchies you can hold down the ALT button when toggling expansion of an item, to recursively toggle the tree.
  • When you're using Debug.Log or related methods, provide the instance of the script so you can click the log output and have the relevant object selected in editor! Debug.Log("Test", this);
  • If you're placing objects in the screen and want them to "snap" into place (great for placing items on the ground) you can hold the Command key (Control on Windows) while dragging the object's axis (snap increments are defined in Edit->Snap Settings)
  • Importing classes in JavaScript. Tired of writing Debug.Log and SendMessageOptions.DontRequireReceiver? Did you know that static members of classess and enums can be imported just like importing namespaces. Simply add import UnityEngine.Debug; and import UnityEngine.SendMessageOptions and then you can write Log("my log string") and SendMessage("ApplyDamage",2.0,DontRequireReceiver);.
  • Deleting objects. Use Command + Backspace in the Scene, Hierarchy and Project views to remove objects. In the Scene and Hierarchy views this will just remove the selected instance of the object. In the Project view this will remove the selected object file and put it in your system Trash.
  • If you need some textures, like font textures, to not be affected by Texture.masterTextureLimit, disable Generate Mip Maps in the texture's import settings. On the down side, this can adversely affect clarity of rendering at smaller scales.
  • Boo has some handy built-in functions like shell(), join() and reversed(). And the cool part? They are available from JavaScript as well.
  • Every built-in component in the inspector has a small question mark in the right of it's heading. That's the quickest way to open the context-help for that component. It's your friend.
  • To remember which color means what on an axis in Unity, just remember the mnemonic: RGB = XYZ.
  • You can use keyboard shortcuts for Edit->Load Selection and Edit->Save Selection to speed up the selection of commonly used parts in your scene.
  • If you option-click an object in your hierarchy, the entire hierarchy within it will expand and unexpand.
  • You can write Editor scripts to greatly reduce project-specific tedium when making something with Unity. These are just as easy to write as regular scripts, and can save you a lot of hassle. See the Wizard Archive for some examples.
  • If you have the problem when importing models that Vector3.up points in the wrong direction (or for any of the other directions), make the game model in question the child of a blank game object, and orient it correctly in local space.
  • When assigning properties of components in the Inspector, you can click on the triangle to pop up a menu of choices. Type in the name of the thing you want and press enter to assign it. This can be a speedy alternative to using drag-and-drop.
  • When entering text in the Inspector view, you can press option-return to get a new line. This is useful for writing multiline things with GUIText objects.
  • If you only have one editor view and no game views in the Unity pane set up, the editor view will be automatically replaced with a game view when you enter play mode and back again when you press stop. This is a nice feature when you are working on a small monitor.
  • Use Tags to assign your own categories and attributes to game objects. Then scripts can refer to the tags. Example: if (contact.otherCollider.tag == "Enemy") or GameObject.FindWithTag ("Enemy")
  • If you want to move a file inside of a project use Unity's project view to move it and not the Finder. This way all references and import settings of the file will be maintained.

Note: Place your new tip at the top of the list, not at the bottom.
