如何使用Unity进行360度观察物体？

1.新建js脚本，命名为RotateObserve，双击脚本进行编辑，代码如下

1. var target:Transform;
   
2. var distance = 10.0;
   
3. var xSpeed = 250.0;
   
4. var ySpeed = 120.0;
   
5. var yMinLimit = -20;
   
6. var yMaxLimit = 80;
   
7. var distanceMin = 3;
   
8. var distanceMax = 15;
   
9. var x = 0.0;
   
10. var y = 0.0;
    
11. //@script AddComponentMenu("Camera-Control/Mouse Orbit");
    
12. function Start () {
    
13.     var angles = transform.eulerAngles;
    
14.     x = angles.y;
    
15.     y = angles.x;
    
16.     // Make the rigid body not change rotation
    
17.     if (rigidbody)
    
18.         rigidbody.freezeRotation = true;
    
19. }
    
20. function LateUpdate () {
    
21.     if(Input.GetAxis("Fire1")==0)return;
    
22.     if (target) {
    
23.         x += Input.GetAxis("Mouse X") * xSpeed * distance* 0.02;
    
24.         y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
    
25.         var rotation = Quaternion.Euler(y, x, 0);
    
26.         distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel")*5, distanceMin, distanceMax);
    
27.         var hit : RaycastHit;
    
28.         if (Physics.Linecast (target.position, transform.position, hit)) {
    
29.             distance -= hit.distance;
    
30.         }
    
31.         var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
    
32.         transform.rotation = rotation;
    
33.         transform.position = position;
    
34.     }
    
35. }

2.将脚本拖曳至场景相机，将需要观察的物体拖曳至Transform下，运行即可。
