如何将图像附加到氩气中的参考系，以便它随相机移动到用户将手机移动到的任何位置

Question

How do I attach an image to the reference frame in argon so that it moves with the camera based wherever the user points the phone? Basically, I want it to be like a HUD, and in my case, it will just be a still image that I've designed in photoshop that I want to work like a map key.

I've tried the following based on some A-Frame documentation, but it doesn't seem to be working. It doesn't seem to alter the application at all. I put this within my ar-scene.

<ar-camera>
      <a-entity>

        <a-image src="#imgKey" width="4" height="2" scale="1 1 1" position="0 0 0">
        </a-image>

      </a-entity>
</ar-camera>

Any ideas?

Here is the code that worked. Simply put this within the ar-scene. It was a positioning issue:

 <a-entity position="0 0 5">

      <ar-camera>

          <a-image src="#imgKey" width="4" height="2" scale="1 1 1" position="0 0 -5"></a-image>

      </ar-camera>

  </a-entity>
