Move and zoom target camera at the same time

Hi guys,
I found this awesome script for a target camera, but I want to add an iTween animation to it, where if a user presses a keyboard key, the camera moves to a new target position and zooms in at the same time. I figured out how to get it to move, but I can't get it to zoom in while its moving..

Here is the script

Code (CSharp):

1. using UnityEngine;
2.  
3. public class camera : MonoBehaviour
4. {
5.  
6.      public Transform target;
7.      public Vector3 targetOffset;
8. public Transform moveTarget;
9.  
10.      public float distance = 5.0f;
11.      public float maxDistance = 20;
12.      public float minDistance = .6f;
13.      public float xSpeed = 200.0f;
14.      public float ySpeed = 200.0f;
15.      public int yMinLimit = -80;
16.      public int yMaxLimit = 80;
17.      public int zoomRate = 40;
18.      public float panSpeed = 0.3f;
19.      public float zoomDampening = 5.0f;
20.      private float xDeg = 0.0f;
21.      private float yDeg = 0.0f;
22.      private float currentDistance;
23.  
24.      float distanceBetween;
25.      private float desiredDistance;
26.      private Quaternion currentRotation;
27.      private Quaternion desiredRotation;
28.      private Quaternion rotation;
29.      private Vector3 position;
30.      void Start() { Init(); }
31.      void OnEnable() { Init(); }
32.      public void Init()
33.      {
34.          //If there is no target, create a temporary target at 'distance' from the cameras current viewpoint
35.          if (!target)
36.          {
37.              GameObject go = new GameObject("Cam Target");
38.              go.transform.position = transform.position + (transform.forward * distance);
39.        
40.          }
41.          distance = Vector3.Distance(transform.position, target.position);
42.          currentDistance = distance;
43.          desiredDistance = distance;
44.          //be sure to grab the current rotations as starting points.
45.          position = transform.position;
46.          rotation = transform.rotation;
47.          currentRotation = transform.rotation;
48.          desiredRotation = transform.rotation;
49.          xDeg = Vector3.Angle(Vector3.right, transform.right);
50.          yDeg = Vector3.Angle(Vector3.up, transform.up);
51.      }
52.      /*
53.       * Camera logic on LateUpdate to only update after all character movement logic has been handled.
54.       */
55.      void LateUpdate()
56.      {
57.  
58.    
59.         //Camera Orbit
60.  
61.          if (Input.GetMouseButton(0))
62.          {
63.              xDeg += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
64.              yDeg -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
65.    
66.              //Clamp the vertical axis for the orbit
67.              yDeg = ClampAngle(yDeg, yMinLimit, yMaxLimit);
68.    
69.              desiredRotation = Quaternion.Euler(yDeg, xDeg, 0);
70.              currentRotation = transform.rotation;
71.              rotation = Quaternion.Lerp(currentRotation, desiredRotation, 2f);
72.              transform.rotation = rotation;
73.          }
74.  
75.  
76. //NEED SOLUTION HERE!
77.          // Press B to move camera target AND zoom in on the target - how ?
78.  
79.              if (Input.GetKeyUp(KeyCode.B)) {
80.               iTween.MoveTo(target.gameObject,moveTarget.position,0.8f);        
81.  
82.             }
83.  
84.  
85.    
86.          // affect the desired Zoom distance if we roll the scrollwheel
87.  
88.          desiredDistance -= Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * zoomRate * Mathf.Abs(desiredDistance);
89.          //clamp the zoom min/max
90.          desiredDistance = Mathf.Clamp(desiredDistance, minDistance, maxDistance);
91.          // For smoothing of the zoom, lerp distance
92.          currentDistance = Mathf.Lerp(currentDistance, desiredDistance, Time.deltaTime * zoomDampening);
93.          // calculate position based on the new currentDistance
94.          position = target.position - (rotation * Vector3.forward * currentDistance + targetOffset);
95.          transform.position = position;
96.  
97.    
98.      }
99.      private static float ClampAngle(float angle, float min, float max)
100.      {
101.          if (angle < -360)
102.              angle += 360;
103.          if (angle > 360)
104.              angle -= 360;
105.          return Mathf.Clamp(angle, min, max);
106.      }
107. }

Will appreciate all the help I can get, thanks.

 

Go to your camera component. You know that "Field of View" property? Mess with the Field of View slider a little bit: this changes how much the camera is zoomed in. You can use a coroutine to zoom. You'll also need your variables to play a role in this process (such as zoomRate). Alternatively, you could manipulate the camera so that it actually moves towards to object to zoom in. I prefer using the FoV property.

For having movement and zooming at the same time, you could use async to run two methods at the same time: see this.
