This is all very interesting, except that we're fairly far away from our creation and we lack the ability to move around the scene. With traditional iOS devices we can accomplish this by accessing the accelerometer within the device:
Unity encapsulates all of the functionality of the accelerometer into the
Input class and we can use its attributes and methods to connect to the accelerometer and determine what is going on with our device.
- In the Project view create a new JavaScript script by selecting Create | JavaScript. This will create a new script named
NewBehaviourScript. - Double-clicking on this script will open the script in Unity's default editor Unitron. We will cover the other Unity-provided tools that can be used to develop scripts, MonoDevelop, when we deep dive into scripting.
- In the script window we simply enter the code for the script in the
Updatefunction:

Scripts must, generally, be attached to Game Objects to do anything useful. In our case we want to move the camera around so we need to attach this script to the camera. There are two ways to accomplish this in Unity. As with texturing, you could simply drag the script onto the camera.
- In the Hierarchy view select the Main Camera object.
- Then, in the Project view drag the script from the Project view onto either the Camera in the Inspector view or onto the object in the Hierarchy view.
The other way to accomplish this task is to select the Main Camera in the Hierarchy view and, subsequently, in the Unity menu bar select Component | Scripts | New Behaviour Script.
In either case you will find that Unity has added your script to the camera:
