Transform.eulerAngles

Description

The rotation as Euler angles in degrees.

The x, y, and z angles represent a rotation z degrees around the z axis, x degrees around the x axis, and y degrees around the y axis.

Only use this variable to read and set the angles to absolute values. Don't increment them, as it will fail when the angle exceeds 360 degrees. Use Transform.Rotate instead.

// Print the rotation around the global X Axis
print (transform.eulerAngles.x);
// Print the rotation around the global Y Axis
print (transform.eulerAngles.y);
// Print the rotation around the global Z Axis
print (transform.eulerAngles.z);

// Assign an absolute rotation using eulerAngles
var yRotation : float = 5.0;
function Update () {
    yRotation += Input.GetAxis("Horizontal");
    transform.eulerAngles = Vector3(10, yRotation, 0);

}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public float yRotation = 5.0F;
    void Update() {
        yRotation += Input.GetAxis("Horizontal");
        transform.eulerAngles = new Vector3(10, yRotation, 0);
    }
    void Example() {
        print(transform.eulerAngles.x);
        print(transform.eulerAngles.y);
        print(transform.eulerAngles.z);
    }
}

Do not set one of the eulerAngles axis separately (eg. eulerAngles.x = 10; ) since this will lead to drift and undesired rotations. When setting them to a new value set them all at once as shown above. Unity will convert the angles to and from the rotation stored in Transform.rotation.
