aframe Scene Running Content Scripts on the Scene


Example

The recommended way is to write a component, and attach it to the scene element.
The scene and its children will be initialized before this component.

AFRAME.registerComponent('do-something', {
  init: function () {
    var sceneEl = this.el;
  }
});
<a-scene do-something></a-scene>

If for some particular reason you prefer not to write a dedicated component you need to wait for the scene to finish initializing and attaching:

var scene = document.querySelector('a-scene');

if (scene.hasLoaded) {
  run();
} else {
  scene.addEventListener('loaded', run);
}

function run () {
  var entity = scene.querySelector('a-entity');
  entity.setAttribute('material', 'color', 'red');
}
