Need to rotate object at a constant rate

Hi all, I'm wanting to rotate a object through x number of degrees ( where x entered by user ) on the Y axis & as the title says at a constant rate.
What happens is the rotation starts off slow but increases as the value of the variable " turn" increases. I know this must have something to do with Time.deltatime but I'm not sure how to get round it.
I know ( well hope ) this is probably quite basic stuff for some of you experienced unity users but this is quite new to me.
Any is help appreciated, thanks.

Code (csharp):

1.  
2. public class planepilot : MonoBehaviour {
3.  public float speed;
4.  private string speedtext = "10" ;
5.  public int ATCspeed = 10;
6.  public int newSpeed ;
7.  private string headingtext = "0" ;
8.  public int ATCheading = 0;
9.  public int newHeading;
10.  public float turn ;
11.  public bool turncomplete = false ;
12.  void Start () {
13.  Debug.Log ("plane script added to :: " + gameObject.name);
14.  speed = 80.0f;
15.  }
16.  
17.  // Update is called once per frame
18.  void Update () {
19.  
20.  
21.  transform.position += transform.forward * Time.deltaTime * ATCspeed;
22.  if (Input.GetKey (KeyCode.Return)) {
23.  ATCspeed = newSpeed; ATCheading = newHeading ;
24.  }
25.  
26.  //***************** changes heading ***************
27.  
28.  if ((transform.eulerAngles.y) < ATCheading) { turncomplete = false;
29.  
30.  turn = transform.eulerAngles.y; turn = turn + 0.02f ;
31.  
32.  
33.  
34.  transform.Rotate (0.0f, turn* Time.deltaTime, 0.0f); Debug.Log(" eulerangles.y = " + (transform.eulerAngles.y) + ( " :: TURN  : " + turn ) +
35.   ( "  / ATC heading : " + ATCheading ) );
36.  
37.  }
38.  
39.  if (turncomplete == false) {
40.  if ((transform.eulerAngles.y) > ATCheading ) {
41.  transform.eulerAngles = new Vector3 (0.0f, ATCheading, 0.0f);
42.  turncomplete = true;
43.  }
44.  
45.  }
46.  
47.    }
48.  
49.  

 

The function is not taking an absolute angle, but a rotation angle, so you should have an angle (0.02f ?) multiplied by Time.deltaTime, and not add the current angle to it.
Unless I am a really bad reader of the documentation's example, which is of cource possible.
http://docs.unity3d.com/ScriptReference/Transform.Rotate.html

Hope it helps anyway.

 

If you want to turn it constantly, you musn't change 'turn'. It will then always add turn*Time.deltaTime to your current rotation.

 

Thanks guys I'm now using

Code (csharp):

1.  
2. transform.Rotate(Vector3.up*10* Time.deltaTime);
3.  

Which has solved that problem.
