Camera Rotation Eludes me

Bare with me, I'm not aware of any package that could solve this issue.

Anyways, I have a camera that rotates around my player's X axis (hopefully X and Z at some point).
This is achieved with a rightclick + drag. However the camera follows the rotation of the object when it also rotates. This is not what I want. How do I fix this?

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class CameraController : MonoBehaviour
5. {
6.     public float rotationSpeed = 100.0F;
7.     public float zoomSpeed = 100.0F;
8.     private bool _isRotating;
9.  
10.     private GameObject playerShip;
11.     private Vector3 shipPos;
12.  
13.     void Start()
14.     {
15.         playerShip = GameObject.Find("Ship");
16.     }
17.  
18.  
19.     void Update()
20.     {
21.         shipPos = playerShip.transform.position;
22.         if (Input.GetMouseButtonDown(1))
23.         {
24.             rotating();
25.         }
26.  
27.         if(Input.GetMouseButtonUp(1))
28.         {
29.             notRotating();
30.         }
31.        
32.         if (_isRotating)
33.         {
34.             transform.RotateAround(shipPos, Vector3.up, Input.GetAxis("Mouse X") * rotationSpeed * Time.deltaTime);
35.            
36.  
37.         }
38.  
39.         transform.Translate(Vector3.forward * Input.GetAxis("Mouse ScrollWheel") * zoomSpeed * Time.deltaTime);
40.     }
41.  
42.     void rotating()
43.     {
44.         _isRotating = true;
45.     }
46.  
47.     void notRotating()
48.     {
49.         _isRotating = false;
50.     }
51. }

 

So you want the rotation to happen all the time? Just take away the condition that's restricting it to holding the mouse button. Remove all the "if" statements and whatever is in them, except this line.

Code (CSharp):

1. transform.RotateAround(shipPos, Vector3.up, Input.GetAxis("Mouse X") * rotationSpeed * Time.deltaTime);

 

No that is not exactly what I was looking for, I should have been more specific. I don't want the camera to spin when the player object spins.

I have now achieved it with this:

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class CameraController : MonoBehaviour
5. {
6.     public float rotationSpeed = 1.0F;
7.     public float zoomSpeed = 100.0F;
8.     private bool _isRotating;
9.  
10.     private GameObject playerShip;
11.     private Vector3 offsetX;
12.  
13.     void Start()
14.     {
15.         playerShip = GameObject.Find("Ship");
16.         offsetX = new Vector3(playerShip.transform.position.x, playerShip.transform.position.y + 1.5f, playerShip.transform.position.z - 6.0f);
17.     }
18.  
19.  
20.     void LateUpdate()
21.     {
22.         transform.LookAt(playerShip.transform.position);
23.         if (Input.GetMouseButtonDown(1))
24.         {
25.             rotating();
26.         }
27.  
28.         if(Input.GetMouseButtonUp(1))
29.         {
30.             notRotating();
31.         }
32.      
33.         if (_isRotating)
34.         {
35.             offsetX = Quaternion.AngleAxis(Input.GetAxis("Mouse X") * rotationSpeed * Time.deltaTime, Vector3.up) * offsetX;
36.             transform.position = playerShip.transform.position + offsetX;
37.             transform.LookAt(playerShip.transform.position);
38.         }
39.         transform.position = playerShip.transform.position + offsetX;
40.         transform.Translate(Vector3.forward * Input.GetAxis("Mouse ScrollWheel") * zoomSpeed * Time.deltaTime);
41.     }
42.  
43.     void rotating()
44.     {
45.         _isRotating = true;
46.     }
47.  
48.     void notRotating()
49.     {
50.         _isRotating = false;
51.     }
52. }
53.  

The issue is that the camera shakes violently, so I applied the smooth follow script. But now my zoom function does not work properly. I need to find a way to make the smooth follow adjust the distance based on what the zoom is set to.

EDIT/ Zoom was kind of solved with; mainCamera.fieldOfView -= Input.GetAxis("Mouse ScrollWheel") * zoomSpeed;

Now onto smoothing this out. It's very jerky, multiplying it by time.deltatime smooths it but makes it extremely slow. It's just as slow without multiplying it by zoom speed.

EDIT// http://answers.unity3d.com/questions/519570/help-me-with-smooth-zoom.html Helped with zoom, I wish I figured this all out before posting.

Thanks for stopping by.

 

Code (CSharp):

1. transform.position = Vector3.MoveTowards(transform.position, Vector3.forwatd * Input.GetAxis("Mouse ScrollWheel", zoomSpeed * Time.deltaTime)
