AnimatedGroup.CrossFade?

[AGP]

Is there a way to transition gradually between one animation and another? Something along the lines of Unity's Animator.CrossFade (http://docs.unity3d.com/ScriptReference/Animator.CrossFade.html)? Because that's one of the main things that a rigged object can do that a vertex-animated one can't.

no, not officially. you can blend pose animations with each other and with a skeletal animation but you cannot blend skeletal animations.

but of course you can try to implement it yourself. chase's skeleton helper does skeleton pose interpolation, you can also try that.

Cool, I'll test this one and report back. Thanks.

I'm trying to interpolate between different animations, not SkeletonPoses. I don't even know how SkeletonHelper could help me with this, because all it sees is SkeletonPoses.

[raft]

each time you apply a skin animation, first a skeleton pose is calculated then it's applied to mesh

OK. In this case, I need two SkeletonPoses, and I need them before the character is animated. Where would I call animatedGroup.get(0).getSkeletonPose()?

[raft]

get two clones of SkeletonPose of the group. position each one according to your need. then interpolate them and apply the result to the original SkeletonPose.

The following isn't working.

   animatedGroup.animateSkin(0.04f, IDLE);
   animatedGroup.applyAnimation();
   idlePose = animatedGroup.get(0).getSkeletonPose().clone();
   idlePose.setToBindPose();//NOT SURE IF THIS IS NEEDED. JUST TRYING
   idlePose.updateTransforms();//NOT SURE IF THIS IS NEEDED. JUST TRYING
   animatedGroup.animateSkin(0.04f, WALKS);
   animatedGroup.applyAnimation();
   walkingPose = animatedGroup.get(0).getSkeletonPose().clone();
   walkingPose.setToBindPose();//NOT SURE IF THIS IS NEEDED. JUST TRYING
   walkingPose.updateTransforms();//NOT SURE IF THIS IS NEEDED. JUST TRYING

Then, in the game loop:

        SkeletonPose pose = SkeletonHelper.interpolateSkeletonPose(idlePose, walkingPose, skinFrame+=deltaTime);
        animatedGroup.setSkeletonPose(pose);
        pose.updateTransforms();
        animatedGroup.applySkeletonPose();
        if (skinFrame >= 1.00f)
      //SWITCH TO SECOND ANIMATION

What I get is the character in his static pose during the entire interpolation time (at the end of which, obviously, he switches to the second animation successfully). So, what should I be doing differently?

[raft]

SkeletonPose.clone does not copy the current pose (animation). it just creates a new SkeletonPose attached to same Skeleton. try somthing like:

Code Select Expand

SkeletonPose pose1 = animatedGroup.get(0).getSkeletonPose().clone();
SkeletonPose pose2 = animatedGroup.get(0).getSkeletonPose().clone();

SkinClipSequence clip = animatedGroup.getSkinClipSequence();
clip.getClip(someIndex).applyTo(time, pose1);
clip.getClip(someOtherIndex).applyTo(time, pose2);

SkeletonPose newPose = SkeletonHelper.interpolateSkeletonPose(pose1, pose2, weight);       
animatedGroup.setSkeletonPose(pose);

[AGP]

I had to add

Code Select Expand

pose.updateTransforms();

after setSkeletonPose() before it worked, but it finally did. Thanks a whole lot.
