Rotating around and following an object

Hi guys,

I'm having a problem getting my camera to rotate around my player from a fixed distance whilst following the player. This is the code I'm using so far to follow the player. The only thing missing is the rotation which I can't seem to figure out - I've tried a few different solutions from Google but none seem to work for me. Any help would be appreciated, thanks!

Also I want to do this through code, and not by simply attaching the camera to the player.

Code (csharp):

1.  
2. void Start () {
3.         relativePosition = transform.position - Camera.main.transform.position;
4. }
5.  
6. void Update () {
7.         Camera.main.transform.LookAt(transform.position);
8.         Camera.main.transform.position = transform.position - relativePosition;
9. }
10.  

 

Just an update. I solved the problem by taking a look at the 3rd person camera script provided with Unity, here's the solution:

Code (csharp):

1.  
2. Camera.main.transform.position = transform.position;
3. Camera.main.transform.position += currentRotation * Vector3.back * 10;
4. Camera.main.transform.position += new Vector3(0f, 4f, 0f);
5. Camera.main.transform.LookAt (transform.position);
6.  

Thanks!
