MULTIPLE TARGET CAMERA

Dear all,

I follow this video (

) trying to get my single camera to follow 4 objects but didn't succeed. The camera indeed sets the middle point between the 4 objects, but it cannot enlarge or widen the camera size to cover them, not even two objects as I have tried. I try to have something like this game (https://www.gamasutra.com/blogs/Nic...492/Single_Camera_System_for_Four_Players.php). It gives concept but did not show how he achieves it.

Below is the code I got from the youtube link. Thank you

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. [RequireComponent(typeof(Camera))]
6. public class multiTargetCamera : MonoBehaviour
7. {
8.     public List<Transform> targets;
9.  
10.     public Vector3 offset;
11.     public float smoothTime = .5f;
12.  
13.     public float minZoom = 40f;
14.     public float maxZoom = 10f;
15.     public float zoomLimiter = 50f;
16.  
17.     private Vector3 velocity;
18.     private Camera cam;
19.  
20.  
21.     private void Start()
22.     {
23.  
24.         cam = GetComponent<Camera>();
25.  
26.     }
27.  
28.     private void LateUpdate()
29.     {
30.  
31.         if (targets.Count == 0)
32.             return;
33.  
34.  
35.         move();
36.         zoom();
37.  
38.     }
39.  
40.     void zoom()
41.     {
42.  
43.         float newZoom = Mathf.Lerp(maxZoom, minZoom, getGreatestDistance() / zoomLimiter);
44.         cam.fieldOfView = Mathf.Lerp(cam.fieldOfView, newZoom, Time.deltaTime);
45.  
46.  
47.     }
48.  
49.  
50.     void move()
51.     {
52.  
53.         Vector3 centerPoint = getCenterPoint();
54.         Vector3 newPosition = centerPoint + offset;
55.         transform.position = Vector3.SmoothDamp(transform.position, newPosition, ref velocity, smoothTime);
56.  
57.     }
58.  
59.     float getGreatestDistance()
60.     {
61.  
62.         var bounds = new Bounds(targets[0].position, Vector3.zero);
63.         for (int i = 0; i < targets.Count; i++)
64.         {
65.  
66.             bounds.Encapsulate(targets[i].position);
67.  
68.  
69.         }
70.  
71.         return bounds.size.x;
72.  
73.     }
74.  
75.  
76.     Vector3 getCenterPoint()
77.     {
78.  
79.         if (targets.Count == 1)
80.         {
81.  
82.             return targets[0].position;
83.  
84.  
85.         }
86.  
87.         var bounds = new Bounds(targets[0].position, Vector3.zero);
88.         for (int i = 0; i < targets.Count; i++)
89.         {
90.  
91.  
92.             bounds.Encapsulate(targets[i].position);
93.  
94.         }
95.  
96.         return bounds.center;
97.  
98.  
99.     }
100.  
101.  
102. }
103.  

 

I know it' a bit old but, try to decrease Zoom Limiter to something like ten or twenty.
