Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Getting the tag of an object with Gaze/Raycast

Not sure if this is just a Unity specific issue I need help with or a Hololens issue. Basically , I can't find a way to check the tag of an object with my Gaze/Raycast. Here's some logic -

        Vector3 headPosition = Camera.main.transform.position;
        Vector3 gazeDirection = Camera.main.transform.forward;

        RaycastHit hitInfo;

if(Physics.Raycast(headPosition, gazeDirection, out hitInfo, 30.0f,
spatialMappingManager.LayerMask))
{
if (hitInfo.collider.gameObject.tag == "Interactable")
{
MenuHolder.gameObject.SetActive(true);
MenuHolder.position = hitInfo.point;
}
}

For some reason it does not compare the tag and the if statement is never executed. I got rid of the if statement, and the logic is executed. I made sure my object is tagged Interactable but it still doesn't work for some reason. I may be asking in the wrong forum since this could just be Unity related. Is there any other way for me get object info from a Raycast? Before I was using a trigger zone where the cursor was and I would put a Rigidbody on the object I wanted to get info from, but the world anchor component doesn't like it when an object has a Rigidbody. Pretty stuck on this.

    Try using "Physics.DefaultRaycastLayers" instead of "spatialMappingManager.LayerMask".

  • Just for the records: The physical layer of the raycast has to match the physical layer of the game object. Otherwise the game object is ignored by the raycast.
