addBoneAnimation method

  1. @override
Future addBoneAnimation(
  1. ThermionEntity entity,
  2. BoneAnimationData animation, {
  3. int skinIndex = 0,
  4. double fadeInInSecs = 0.0,
  5. double fadeOutInSecs = 0.0,
  6. double maxDelta = 1.0,
})
override

Enqueues and plays the animation for the specified bone(s). By default, frame data is interpreted as being in parent bone space; a 45 degree around Y means the bone will rotate 45 degrees around the Y axis of the parent bone in its current orientation. (i.e NOT the parent bone's rest position!). Currently, only Space.ParentBone and Space.Model are supported; if you want to transform to another space, you will need to do so manually.

fadeInInSecs/fadeOutInSecs/maxDelta are used to cross-fade between the current active glTF animation ("animation1") and the animation you set via this method ("animation2"). The bone orientations will be linearly interpolated between animation1 and animation2; at time 0, the orientation will be 100% animation1, at time fadeInInSecs, the animation will be ((1 - maxDelta) * animation1) + (maxDelta * animation2). This will be applied in reverse after fadeOutInSecs.

Implementation

@override
Future addBoneAnimation(ThermionEntity entity, BoneAnimationData animation,
    {int skinIndex = 0,
    double fadeInInSecs = 0.0,
    double fadeOutInSecs = 0.0,
    double maxDelta = 1.0}) {
  // TODO: implement addBoneAnimation
  throw UnimplementedError();
