Hi @mazher @mocom,

I've used the example code from Physics.Raycast Unity Scripting API, counted the hits and added an UI to show me on the device if it's happening or not. I can confirm it works as expected.

code below:

public class Raycast : MonoBehaviour

{

    int count = 0;

     public Text scoreText;

    void Update()

    {

        // Bit shift the index of the layer(8) to get a bit mask

        int layerMask = 1 << 8;

        // This would cast rays only against colliders in layer 8.

        // But instead we want to collide against everything except layer 8. The ~ operator does this, it inverts a bitmask.

        layerMask = ~layerMask;

        RaycastHit hit;

        // Does the ray intersect any objects excluding the player layer

        if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, Mathf.Infinity, layerMask))

        {

            Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * hit.distance, Color.red);

            Debug.Log("Did Hit");

            count++;

            scoreText.text = count.ToString();

        }

        else

        {

            Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 1000, Color.white);

            Debug.Log("Did not Hit");

        }

    }

I've added the script to the ARCamera.

Tested on an Android Device.

Hope it helps.

Thank you.

Did you manage to get this working? I am having the same issue.

Hi, did you manage to find a solution to this?

I am facing the same problem. Raycast is not working with ARCamera.  

Note:  Raycast is working perfectly fine on Unity Editor but not working on device.

   Please advice me what to do I have already waisted a lot of time trying fixing this.

   RaycastHit hitInfo;

   int layerMask = 1 << 8;

   if (Physics.Raycast (arCamera.ScreenPointToRay ( Input.mousePosition), out hitInfo, Mathf.Infinity, layerMask)) {

     Debug.Log ("Physics.Raycast (ray, out hitInfo)");

    }

Hi,

have you checked this:

https://developer.vuforia.com/resources/dev-guide/unity-drag-ar-object-screen-your-finger

This is an example of how the Unity RaycastHit technique can be used with a Vuforia ARCamera, and this has been tested and verified that works. The ARCamera per-se should have no issue with raycasting... of course there other elements that might play a role, such as the Max picking distance of the raycast;

for example, you may want to use:

Physics.Raycast(ray, out hit, maxPickingDistance)

(and choose an appropriate value for the maxPickingDistance parameter),  instead of:

Physics.Raycast(ray, out hit)

I hope this helps.
