title: A-Frame: how to animate objects on scene with scenario
body: <p>Let's speak about 3D movies or smth like that. Ok, I know how to animate properties with <code>&lt;a-animation&gt;</code>. I also tried <a href="https://github.com/ngokevin/kframe" rel="nofollow noreferrer"><code>aframe-animation-component</code></a> based on animejs. I love animejs. It have useful <code>anime.timeline()</code>. You can just set frames of this and animate much objects as you want. But it have very serious trouble: it isn't able animate complex attributes like <code>position</code> or <code>scale</code> or another serialized component. This trouble I've described <a href="https://github.com/juliangarnier/anime/issues/211" rel="nofollow noreferrer">here</a>. Animejs's timeline is perfect for DOM, but very hard to use with A-Frame.
  I also found <a href="https://threejs.org/examples/#webgl_animation_keyframes_json" rel="nofollow noreferrer">this example</a> for three.js. May be I can generate same animation for my A-Frame scene? Looking for any suggestions about scene's keyframes or timelines.</p>
