I edited my code to show a full example.
You're placing the box at "-1 0 -1" regarding the camera. But the camera isn't moving. It's just rotating. So it's world position isn't changing at all.
either:
translate the coordinates to the camera local space of reference
get the camera direction vector, and add it to the camera
Direction option:

el.addEventListener('click', function() {
const acamera = document.querySelector('a-scene').camera.el.object3D
acamera.getWorldDirection(dir);
dir.multiplyScalar(-2);
dir.add(acamera.position)
el.setAttribute('animation', {

});

Since it's a rig with camera as child, the position should not be read on the camera object but on the camera parent object.
document.querySelector("a-scene").camera.el.parentNode.object3D.position

Good morning, how are you? I ask a question, Im making a game in AR of soccer penalties. I am using a-frame and ammo.js for physics.
I wanted to know how I can make a shot of the ball once the screen is touched, taking into account the position and the view of the camera.
I could use cannon.js but due to non-updated features of the library I had to migrate to ammo.js
I'm very busy and the ammo.js documentation lacks information about it. Any tip is welcome, thank you very much

I (a very amateur programmer) am trying to make an environment in A-frame where you point a cursor at different objects and it changes the displayed value on a thermometer: https://fst-retail-safety.glitch.me
The site never loads completely on the first try but reliably loads upon refresh. If I omit the cursor listener from the GLTF used for the environment, it also loads correctly. Any ideas on how to fix this? Perhaps the cursor is trying to fuse with the background object before it loads and it's causing an error? Many thanks for any help.

I've opened it up, and when something in the scene isn't loaded, there is a nice log in the console:
Uncaught TypeError: Cannot read property 'array' of undefined
at TextGeometry.computeBoundingSphere (index.js:96)
at P.raycast (three.js:8649)
(....)
No need to search for the array of undefined - the rest tells us that there is an issue with raycasting the text elements.
Since you only want to interact with certain things (which aren't text elements), you can specify which items should the cursor interact with:
<!-- let them share a common class -->
<a-box class="interactable></a-box>
<!-- raycaster setup -->
<a-entity
cursor="fuse: true; fuseTimeout: 100"
raycaster="objects: .interactable">
</a-entity>
Like i did in this remix
The problem:
I want to make a ball the user can throw. With my current implementation, physics work but I cannot lift the ball. However, if I delete the "dynamic-body" I can grab the ball exactly as I am supposed to, and move it around. Heck, I tried changing it to "static-body" and it still works. The problem seems to be whenever I mix grabbable and dynamic-body. I know it should be possible in an older version, as I was using this tutorial: https://www.youtube.com/watch?v=SKYfYd3pk4I
However, he is using progressive-controls which are not available in the newest super-hands package, I don't know if that changes anything. Is there anything I am doing wrong here?
Here are my snippits of code that could affect the result:

Thanks to this: https://github.com/bryik/aframe-ball-throw/blob/master/index.html
I found the culprit.
I needed to add the static-body to my hand-entities, so that collision could be detected. No idea why collision was detected without them before though.
Modified code:
<a-entity static-body="shape: sphere; sphereRadius: 0.02;" sphere-collider="objects: .interactable" handModelStyle: lowPoly; super-hands hand-controls="hand: left"></a-entity>

I'm using gaze buttons but when the click event is triggered, the function is executed two times. See code snippet below.

How could I prevent this situation of two times clicking on an object? It must be triggered just one time when it's clicked.
I've made a workaround to prevent this issue
var number = 0;
document.getElementsByTagName('a-sphere')[0].addEventListener('click', function(){
if(this.getAttribute('data-clicked') === null || this.getAttribute('data-clicked') === 'false') {
this.setAttribute('data-clicked', 'true');
alert('You\'ve clicked the sphere ' + (++number) + ' times.');
}
else {
this.setAttribute('data-clicked', 'false');
}
});

<a-scene>
<!-- this is my object that must execute a click event when looked -->
<a-sphere position="0 0 -7" color="red">
</a-sphere>
<!-- camera -->
<a-camera look-controls wasd-controls cursor="maxDistance: 30; fuse: true">
<!-- progress bar -->
<a-entity position="0 0 -3" geometry="primitive: ring; radiusOuter: 0.07;radiusInner: 0.05;" material="color: cyan; shader: flat"
cursor="maxDistance: 30; fuse: true">
<!--<a-cursor color="red"></a-cursor>-->
<a-animation begin="click" easing="ease-in" attribute="scale" fill="backwards" from="0.1 0.1 0.1" to="1 1 1" dur="150"></a-animation>
<a-animation begin="fusing" easing="ease-in" attribute="scale" fill="forwards" from="1 1 1" to="0.1 0.1 0.1" dur="1500"></a-animation>
</a-entity>
</a-camera>
</a-scene>
Of course this is not a good way of preventing the issue, but it's working.
I want to add gradient color to the sphere, currently I am setting the color:
<a-sphere position="1 1 0" color="#ef2d5e">
<a-animation attribute="rotation" to="0 360 0" dur="10000" easing="linear" repeat="indefinite">
</a-animation>
</a-sphere>
Demo
How do I add gradient to the sphere? Is there any way.
