I'm trying to create a web page that contains an A-Frame box that rotates 90 degrees when it's clicked. I've tried various things including using the aframe-event-set-component library. I can't quite seem to get it to work. I suspect I have a syntax problem but I cannot figure out my mistake.
Any help you can provide would be greatly appreciated.
The following is my code using the aframe-event-set-component.
Thanks in advance for your help.

Timothy,
If You wanna just rotate it, add the rotation attribute to the event:
event-set__1="_event: click; material.color:#ff0000;rotation:0 90 0"
On the other hand, i presume you want to have an animation, so You will have to either:
use the <a-animation> component, or use kevin's ngo animation-component: https://github.com/ngokevin/kframe/tree/master/components/animation
You'd need to declare an animation to 0 90 0, make a startEvent, and make the click emit that event:
<a-entity geometry="primitive: box" material="color: #FCB241"
event-set__1="_event: click; material.color:#ff0000;"
event-set__2="_event: mouseenter; material.color: #0000ff"
event-set__3="_event: mouseleave; material.color: #FCB241"
position="-1 0 -2"
animation__rotate="property: rotation; dir: forward; dur: 1000;
easing: easeInSine; loop: false; to: 0 90 0;
startEvents:click">
</a-entity>
The following plunk shows how to make it rotate on click with the animation component:
https://plnkr.co/edit/k9Jc5qEG0ckEovquEZi4?p=preview
If You don't want the animation, just replace Your event-set__1 with mine.
PERSONALLY i'd rather register my own component # AFRAME.registerComponent (name, definition), because I like to handle events by on own.

I am creating a scene in A-frame and I'm wondering how I can create something where when a function called myFunction() occurs, an animation will start. How can this be done? Current code:
<html>
<head>
<script src="https://aframe.io/releases/1.2.0/aframe.min.js"></script>
</head>
<body>
<a-scene>
<a-box position="-1 1.6 -5" animation="property: position; to: 1 8 -10; dur: 2000; easing: linear; loop: true" color="tomato"></a-box>
<a-plane position="0 0 -4" rotation="-90 0 0" width="4" height="4" color="#7BC8A4"></a-plane>
<a-sky color="#ECECEC"></a-sky>
</a-scene>
</body>
</html>
You would want to use the startEvents in the animation attribute
animation="startEvents: event-name; property: position; to: 1 8 -10; dur: 2000; easing: linear; loop: true"
add a class or id to your element so your function could identify the element you want to animate on command
<a-box class="class_name" position="-1 1.6 -5" animation="startEvents: event-name; property: position; to: 1 8 -10; dur: 2000; easing: linear; loop: true" color="tomato"></a-box>
emit the startEvent by its name in the function
function animateBox() {
document.querySelector('.class_name').emit('event-name');
}
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:

And finally, the a-scene defining the gravity:
<a-scene embedded antialias="false" physics="gravity: -9.8; debug: true">
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>
<a-entity static-body="shape: sphere; sphereRadius: 0.02;" sphere-collider="objects: .interactable" handModelStyle: lowPoly; super-hands hand-controls="hand: right"></a-entity>
I'm having an issue where I can't properly set the trigger event for an animation
I have a cursor
It should animate itself when it is pointed at a specific entity
The property-value pair of "startEvents: fusing" within the animation attribute doesn't work, as well as other variations like "fuse" and "fused"
My a-frame version is 0.9.2
<a-camera position="0 3 0"
wasd-controls
look-controls>
<!-- Cursor (NOTE: having issues with animation here)-->
<a-cursor fuse="true"
fuse-timeout="250"
position="0 0 -1"
geometry="primitive: ring;
radiusInner: 0.02;
radiusOuter: 0.03"
material="color: white;
shader: flat;
opacity: 0.5"
raycaster="objects: .clickable"
scale="1 1 1"
animation="startEvents: fusing;
property: scale;
from: 1 1 1;
to: 0.5 0.5 0.5;
dur: 500"
>
<a-circle radius="0.01"
color="white"
opacity="0.5"
material="shader:flat"></a-circle>
</a-cursor>
</a-camera>
<a-entity class="orb clickable"
id="orb0"
scale="1 1 1"
position="0 3 -6"> </a-entity>
The cursor needs to be a child object of a camera element, like this:
<a-camera>
<a-cursor animation="startEvents: fusing;...."></a-cursor>
</a-camera>
fusing should be working, also mouseleave will be helpful to change the cursor when you move it away from the object. Check it out in this fiddle.
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>

How do I add gradient to the sphere? Is there any way.

Hi I am using the master branch for aframe and the new text "component" seems to be going below the allocated height of the entity it resides in with some invisible stuff. Codepen here http://codepen.io/anon/pen/PWQXRP and try to move below the entity. Code here which was modified from the 360-image-gallery-boilerplate repo

new to aframe so have no clue what I am doing wrong
https://aframe.io/docs/master/components/text.html#scaling-geometry-to-fit-text
Scaling Geometry to Fit Text
To have the geometry automatically scale with the text, set the geometry component’s width and height properties to auto, and set the text component’s width as desired. In this example, the plane’s width will be set to 4 units, and its height will be set to match the actual height of the text:
<a-entity
geometry="primitive: plane; height: auto; width: auto"
material="color: blue"
text="width: 4; value: This text will be 4 units wide."></a-entity>
Note that if neither geometry nor text specify a width, the text width property will default to 1 unit (meter), and the geometry width property will then become 1 unit as well.
<a-entity
geometry="primitive: plane"
material="color: blue"
text="value: 1-wide\ndefault."></a-entity>
