Question Problem when I using AnimationTrack and My Custom TransformTrack

Hi,
I was create a custom timeline track which can modify transform like position and rotation, When I used it indivisually, It worked perfectly.



But if I add an animation by using "AnimationTrack", "TransformTrack" will not work anymore.



BTW, AnimationClip contains a root motion, if I remove it, "TransformTrack" could work again. I wonder if I can find a way to disable the root motion of "AnimationTrack" can solve the problem.


Here is my code:

Code (CSharp):

1. public class TransformMixerBehaviour : PlayableBehaviour
2.     {
3.         public override void ProcessFrame(Playable playable, FrameData info, object playerData)
4.         {
5.             var trans = playerData as Transform;
6.  
7.             if (!trans)
8.                 return;
9.  
10.             bool setData = false;
11.             Vector3 position = Vector3.zero;
12.             Vector3 eulerAngles = Vector3.zero;
13.  
14.             int inputCount = playable.GetInputCount();
15.             for (int i = 0; i < inputCount; i++)
16.             {
17.                 float inputWeight = playable.GetInputWeight(i);
18.                 if (inputWeight > 0f)
19.                 {
20.                     setData = true;
21.  
22.                     var inputPlayable = (ScriptPlayable<TransformBehaviour>)playable.GetInput(i);
23.                     var transformBehaviour = inputPlayable.GetBehaviour();
24.  
25.                     position += transformBehaviour.position * inputWeight;
26.                     eulerAngles += transformBehaviour.eulerAngles * inputWeight;
27.                 }
28.             }
29.  
30.             if (setData)
31.             {
32.                 trans.localPosition = position;
33.                 trans.localEulerAngles = eulerAngles;
34.             }
35.         }
36.     }

How can I make the TransformTrack works and keep the root motion of AnimationClip

If anyone know the answer, please please help me.

 

The problem you have is that both tracks update the same transform every frame.
If you want both tracks to work simulataniuosly you would have to modifiy both, that they dont do it!

 

man i just find my trouble is same with you.

 

Hi guys, I found a way to solve this.
1.add a MonoBehaviour script to the animated Gameobject
2.Here is the script (It's little hacky..):

Code (CSharp):

1.     [ExecuteInEditMode]
2.     public class RootMotionController : MonoBehaviour
3.     {
4.         private Animator _anim;
5.  
6.         private void Start()
7.         {
8.         }
9.  
10.         //This function will block the root motion
11.         private void OnAnimatorMove()
12.         {
13.             if (null == _anim)
14.             {
15.                 _anim = GetComponent<Animator>();
16.             }
17.  
18.             if (null != _anim)
19.             {
20.                 //if you want use root motion here
21.                 _anim.ApplyBuiltinRootMotion();
22.             }
23.         }
24.     }

Now you can control the transform but keep the animation root motion.

But I still can't get over it why Unity doesn't add a toggle "Enabled Root Motion" on the Animator Component.

 

Hi , I want this animation to play in timeline like an animator .




Here is my anim clip.
