I'm trying to get the cylinder to begin and pause rotating on mouse click but I can only get it to begin, not stop. I'm not sure what else would work? When I add the end condition it stops working all together. My question is, how can I get the begin and end conditions to be the same input?

I would threw the logic to a seperate a-frame component.
Having a setup like this:
<a-cylinder animation-controller
animation="resumeEvents: start; pauseEvents: pause">
</a-cylinder>
When clicked - switch a boolean, and depending on the value start or stop the animation:
<script src="https://aframe.io/releases/1.3.0/aframe.min.js"></script>
<script>
AFRAME.registerComponent("animation-controller", {
init: function() {
this.running = false
this.el.addEventListener("click", (e) => {
if (!this.running) {
this.el.emit("start") // animation not running - start it
} else {
this.el.emit("pause") // animation running - stop it
}
this.running = !this.running // flip the flag
})
}
})
</script>
<a-scene cursor="rayOrigin: mouse">
<a-cylinder animation-controller position="0 1 -3" color="red"
animation="property: rotation; to: 0 0 360; dur:1000; loop: true; resumeEvents: start; pauseEvents: pause">
</a-cylinder>

this.running = false
this.animComp = document.querySelector("a-animation")
this.el.addEventListener("click", (e) => {
if (!this.running) {
this.animComp.emit("start") // animation not running - start it
} else {
this.animComp.emit("stop") // animation running - stop it
}
this.running = !this.running // flip the flag
})
}
})
Simple - if the animation is running - start it. Otherwise stop it.
Fiddle here.
