Camera glitches into wall

Hey together, i need help. To prevent that my camera moves into a mesh i use physics.linecast. Basically it works, but as you can see in the attached video the linecast glitches into the collider if i move or stop in the right position/camera angle.

Any idea how i can solve this?

Code (CSharp):

1.            
2. if (Physics.Linecast(new Vector3(transform.position.x, transform.position.y, transform.position.z),                                                           camHitPoint.transform.position, out hit))
3.             {
4.                 camHitPoint.transform.position = Vector3.Lerp(camHitPoint.transform.position, hit.point, (15 *                                                                                                           Time.deltaTime));
5.             }
6.             else
7.             {
8.                 camHitPoint.transform.localPosition = Vector3.Lerp(camHitPoint.transform.localPosition, camStartPos,                                                                                                   (10*Time.deltaTime));
9.             }

this is what i use to prevent camera clipping:

Code (CSharp):

1. Ray ray = new Ray(target.position, transform.position-target.position);
2.         RaycastHit hit;
3.         Debug.DrawRay(ray.origin, ray.direction*distance);
4.         LayerMask mask = LayerMask.NameToLayer("Level");
5.         if(Physics.Raycast(ray, out hit, preferedDistance, 1<<mask.value))
6.         {
7.                     float currentDistance = Vector3.Distance(hit.point, target.position);
8.                 if(currentDistance < preferedDistance)
9.                     distance = currentDistance - 0.1f;
10.  
11.         }
12.         else
13.             distance = preferedDistance;
14.            
15.        
16.         if(distance <= 0)
17.             distance = 0.1f;

 

First, thank you.

Which layer do you ignore? And were do you set the cam position?

 

it only casts again everything in de layer "Level".
it's for a 3rd controller, so the camera is set by a mouseorbit script around the player.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class MouseOrbit : MonoBehaviour
5. {
6.  
7.     public Transform target;
8.     public static float distance = 2.0f;
9.     private float preferedDistance;
10.  
11.     public float xSpeed = 250.0f;
12.     public float ySpeed = 120.0f;
13.  
14.     public int yMinLimit = -20;
15.     public int yMaxLimit = 80;
16.  
17.     private float x = 0.0f;
18.     private float y = 0.0f;
19.  
20.     void Start ()
21.     {
22.         preferedDistance = distance;
23.         Vector3 angles = transform.eulerAngles;
24.         x = angles.y;
25.         y = angles.x;
26.  
27.            if (rigidbody)
28.             rigidbody.freezeRotation = true;
29.     }
30.  
31.     void LateUpdate ()
32.     {
33.         if(target)
34.         {
35.             x += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
36.             y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
37.            
38.              y = ClampAngle(y, yMinLimit, yMaxLimit);
39.                  
40.             Quaternion rotation = Quaternion.Euler(y, x, 0);
41.             Vector3 position = rotation * new Vector3(0.0f, 0.0f, -distance) + target.position;
42.          
43.             transform.rotation = rotation;
44.             transform.position = position;
45.         }
46.         Ray ray = new Ray(target.position, transform.position-target.position);
47.         RaycastHit hit;
48.         Debug.DrawRay(ray.origin, ray.direction*distance);
49.         LayerMask mask = LayerMask.NameToLayer("Level");
50.         if(Physics.Raycast(ray, out hit, preferedDistance, 1<<mask.value))
51.         {
52.  
53.                 float currentDistance = Vector3.Distance(hit.point, target.position);
54.                 if(currentDistance < preferedDistance)
55.                     distance = currentDistance - 0.1f;
56.         }
57.         else
58.             distance = preferedDistance;
59.          
60.      
61.         if(distance <= 0)
62.             distance = 0.1f;
63.     }
64.  
65.     static float ClampAngle (float angle, float min, float max)
66.     {
67.         if (angle < -360)
68.             angle += 360;
69.         if (angle > 360)
70.             angle -= 360;
71.         return Mathf.Clamp (angle, min, max);
72.     }
73. }
74.  

 

So, took me a while to figure it out but now it works very smooth, thank you very much my friend!

 

no problem, glad it works for you.
