update method

AnimationMixer update(num deltaTime)

Advance the time and update apply the animation

This is usually done in the render loop, passing clock.getDelta scaled by the mixer's timeScale.

Implementation

AnimationMixer update(num deltaTime) {
  deltaTime *= timeScale;

  final actions = _actions,
      nActions = _nActiveActions,
      time = this.time += deltaTime,
      timeDirection = deltaTime.toDouble().sign,
      accuIndex = _accuIndex ^= 1;

  // run active actions

  for (int i = 0; i != nActions; ++i) {
    final action = actions[i];
    action.update(time, deltaTime, timeDirection, accuIndex);
  }

  // update scene graph

  final bindings = this.bindings;
  final nBindings = _nActiveBindings;

  for (int i = 0; i != nBindings; ++i) {
    final binding = bindings[i];
    binding.apply(accuIndex);
  }

  return this;
}
