title: How to detect when a scene is loaded in A-Frame?
body: <p>Is there some event that is triggered when A-Frame is fully loaded? Right now I’ve managed to get my <code>document.querySelector(".a-enter-vr-button")</code> working, but only after placing it inside a <code>setTimeout</code> function, which seems a bit of a makeshift solution. So if anyone has any way of making a js script fire after A-Frame has fully loaded please let me know!</p>
