Rotate Script for AR Model

• This example uses an existing Unity project already set up with a static model through Vuforia.
• Create a new C# script asset in Unity.
• Name it Rotate.
• Open it in MonoDevelop to edit the code as shown below.
• Save the C# script.
• Compile (Run) the code within MonoDevelop.
• Drag & drop the C# script asset to the object in the Unity workspace so that it acquires the script.
• Run the game to see the object asset rotate at the speed set by the C# script.

using UnityEngine;
using System.Collections;

public class Rotate : MonoBehaviour {
    public int Speed;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        transform.Rotate (new Vector3 (0,Time.deltaTime*Speed,0));
    }
}

• The variable Speed is added so that it appears as an input in the Unity window under the object in which it is attached to.
• The transform method is used to rotate the object.
• Rotate uses 3 values, one for each vector direction, so the axis for rotation needs to be defined.
• A new vector is added within Rotate.
• The vector values are (x,y,z) and since the rotation is to be about the y-axis, the other 2 values are set to 0.
• The Time.deltaTime method is used to define at what speed the rotation about the y-axis will occur.
• It is multiplied by the variable Speed so that we can make the speed modification through the Unity object parameter outside of the script file.
