Placement of object jittering when using ScreenPointToRay.

Hello, so im using a raycast from the main camera to the mouse position to determine the position of placing objects down (in this case a chest), but I get really bad jittering. I have deduced that it is most likely something to do with the raycast itself. I have Tried lerping, using fixedUpdate, LateUpdate and OnGui and it doesn't make any difference. The camera is not moving at all so I know its not the camera as well. I do get slight changes in position with the ray cast even though the mouse is still, not sure if it is related to this.

I have also isolated the code to simply raycast and set position based on this code:

Code (CSharp):

1.      
2.          
3.                     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
4.                     RaycastHit hit;
5.                     if (Physics.Raycast(ray, out hit))
6.                     {
7.                         //transform.LookAt(hit.point);
8.  
9.                         Debug.LogWarning("hit: " + hit.point + " hit ob: " + hit.collider.gameObject);
10.                         Vector3 dir = (hit.point - transform.position );
11.  
12.                         transform.rotation = Quaternion.LookRotation(dir,Vector3.up);
13.  
14.  
15.                     }

Here is what I am currently using to determine the head position.

Code (CSharp):

1.  
2. using UnityEngine;
3. using MLAPI;
4.  
5.  
6. public class LookRotation : NetworkBehaviour
7. {
8.     public bool freezeRotation;
9.     public GameObject mainBody;
10.     float xRotation;
11.     float yRotation;
12.     public float horizontalSpeed;
13.     public float verticalSpeed;
14.  
15.     void OnGUI()
16.     {
17.         if (IsLocalPlayer)
18.         {
19.             if(freezeRotation == false)
20.             {
21.                 if (transform.parent.GetComponent<ChangeCameraView>().isOverview == false)
22.                 {
23.                     float mouseX = Input.GetAxis("Mouse X") * horizontalSpeed;
24.                     float mouseY = Input.GetAxis("Mouse Y") * verticalSpeed;
25.  
26.                     yRotation += mouseX;
27.                     xRotation -= mouseY;
28.                     xRotation = Mathf.Clamp(xRotation, -90, 90);
29.  
30.                     mainBody.transform.eulerAngles = new Vector3(0, yRotation, 0);
31.                     transform.eulerAngles = new Vector3(xRotation, yRotation, 0.0f);
32.                 }
33.                 else
34.                 {
35.  
36.                     if (Input.GetMouseButton(2))
37.                     {
38.                         float mouseX = Input.GetAxis("Mouse X") * horizontalSpeed;
39.                         float mouseY = Input.GetAxis("Mouse Y") * verticalSpeed;
40.  
41.                         yRotation += mouseX;
42.                         xRotation -= mouseY;
43.                         xRotation = Mathf.Clamp(xRotation, -90, 90);
44.  
45.                         mainBody.transform.eulerAngles = new Vector3(0, yRotation, 0);
46.  
47.  
48.  
49.  
50.                     }
51.                     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
52.                     RaycastHit hit;
53.                     if (Physics.Raycast(ray, out hit))
54.                     {
55.  
56.                         Debug.LogWarning("hit: " + hit.point + " hit ob: " + hit.collider.gameObject);
57.                         Vector3 dir = (hit.point - transform.position );
58.  
59.                         transform.rotation = Quaternion.LookRotation(dir,Vector3.up);
60.  
61.  
62.                     }
63.                 }
64.             }
65.         }
66.     }
67. }
68.  

Here is the code to determine the position of the chest.

Code (CSharp):

1.    private void OnGUI()
2.     {
3.         RaycastHit hit;
4.  
5.         if (Physics.Raycast(transform.GetChild(0).transform.position, transform.GetChild(0).transform.forward, out hit, Mathf.Infinity))
6.         {
7.             if (placingItem == false)
8.             {
9.                 if (newTemplate)
10.                 {
11.  
12.                     if (newTemplate.GetComponent<SnapProperties>())
13.                     {
14.                         Vector3 gridSnap = new Vector3(Mathf.RoundToInt(hit.point.x / 2) * 2, Mathf.RoundToInt(hit.point.y / 2) * 2, Mathf.RoundToInt(hit.point.z / 2) * 2);
15.  
16.                         tempWorldPos = gridSnap + newTemplate.GetComponent<BuildingProperties>().templateOffset;
17.                     }
18.                     else
19.                     {
20.                         Debug.LogWarning("hit ob: " + hit.collider.gameObject);
21.                         tempWorldPos =  hit.point + newTemplate.GetComponent<BuildingProperties>().templateOffset;
22.  
23.                     }
24.  
25.                 }
26.                 else
27.                 {
28.  
29.                 }
30.                 if (Input.GetKeyDown(KeyCode.Delete))
31.                 {
32.                     Debug.LogWarning("detected : " + hit.collider.gameObject);
33.                     if (hit.collider.GetComponent<BuildingProperties>())
34.                     {
35.                         if (hit.collider.GetComponent<BuildingProperties>().readyToBuild)
36.                         {
37.                             Debug.LogWarning("deleting: " + hit.collider.gameObject);
38.  
39.                             DestroyItemServerRpc(hit.collider.GetComponent<NetworkObject>().NetworkObjectId);
40.  
41.                         }
42.                     }
43.                     if (hit.collider.transform.parent)
44.                     {
45.                         if (hit.collider.transform.parent.GetComponent<BuildingProperties>())
46.                         {
47.                             if (hit.collider.transform.parent.GetComponent<BuildingProperties>().readyToBuild)
48.                             {
49.                                 Debug.LogWarning("deleting: " + hit.collider.transform.parent.gameObject);
50.                                 DestroyItemServerRpc(hit.collider.transform.parent.GetComponent<NetworkObject>().NetworkObjectId);
51.  
52.                             }
53.                         }
54.                     }
55.  
56.                 }
57.             }
58.         }
59.     }

I hope you can point me in the right direction because im stumped. Any suggestions would be appreciated.

 

bumping because I still have this problem
