No collision possible but SelectionRaycast gives back hit.point

Hi,
So I solved how to create an Object via Raycast with Oculus.
What I wanted to do is create an object at the collision point between oculus touch controller and an object via a Selection Ray.

But now while playing objects are instantiated even though there cannot be a collision.
It is mid air. I tried the script again in a empty scene with only a plane.
But it also happen there.
Most of the time it creates the objects at the right positions.
I don't know if SelectionRaycast may calculates the wrong collision position (hit.point)

This is my code. Do you have a idea what could be wrong?

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3.  
4. public class drawingdots : MonoBehaviour
5. {
6.     [Tooltip("Transform for the dots.")]
7.     public Transform dot = null;
8.     [Tooltip("Tracking space of the OVRCameraRig.\nIf tracking space is not set, the scene will be searched.\nThis search is expensive.")]
9.     public Transform trackingSpace = null;
10.  
11.     public OVRInput.Controller activeController = OVRInput.Controller.None;
12.     private List<Vector3> PointList;
13.     RaycastHit hit;
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.         activeController = ControllerSelection.OVRInputHelpers.GetControllerForButton(OVRInput.Button.PrimaryIndexTrigger, activeController);
19.     }
20.  
21.     void Update()
22.     {
23.         activeController = ControllerSelection.OVRInputHelpers.GetControllerForButton(OVRInput.Button.Any, activeController);
24.         Ray ray = ControllerSelection.OVRInputHelpers.GetSelectionRay(activeController, trackingSpace);
25.  
26.         if (Physics.Raycast(ray, out hit))
27.         {
28.             Vector3 position = hit.point;
29.  
30.             Debug.Log("Button pushed: " + OVRInput.Get(OVRInput.Button.Any));
31.             if (OVRInput.Get(OVRInput.Button.Any))
32.             {
33.                 Instantiate(dot, position, Quaternion.identity);
34.                 Debug.Log("Particle Created");
35.             }
36.             Debug.Log("Position: " + position);
37.         }
38.         else
39.         {
40.             Debug.Log("No Collision");
41.         }
42.  
43.  
44. }

 

You can print hit gameobject name to the log to see what exactly ray have hitted.

 

Thank you! But now I know that the OVRPlayerController (Transform?)
It should not hit it.
I could not find any Colliders on OVRPlayerController.
It also does not move with the OVRCamera.
What can I do to solve this?
I look at some post with similar problems, but the solutions there did not work for me.

https://developer.oculus.com/documentation/unity/latest/concepts/unity-utilities-overview/
Here I see there should be character controller on the OVRPlayerController, it adds capsule collider. You can solve it using collision mask to exclude player layer or include only placeable surface layer. You must assign correct layers in inspector after that.

 

Thank you so much! I solved it

 

I got the following error.

The name 'ControllerSelection' does not exist in the current context.
