AnimationClip.SetCurve "localEulerAngles" not working

Question

Hello everyone.

I have another issue with the SetCurve function.

I'm trying to set a rotation curve along the Z axis.

Here is my line of code:

 clip.SetCurve("objectname", typeof(Transform), "localEulerAngles.z", rotZcurve);

The data I'm putting in the curve is defiantly not empty.

When I open the Animation editor (t$$anonymous$$s has not$$anonymous$$ng to do with mecanim),

I get the "Clean Up Leftover Curves" Button.

When I click it, I see all the Z rotation I'm trying to do....

Any ideas why unity t$$anonymous$$nk my Z rotation is empty?

Thanks!

Edit

Appearntly it has somt$$anonymous$$ng to do with EulerAngles.

As soon as a change to localRotation, the curve does appear.

The problem is, localRotation uses quaternions.

No matter what I tried to do, I always get the rotation jumping between -180,0 and 180....

Can anyone help me figure it out?

Figured it out.

Apparently, when setting a quaternion rotation, you need to provide the values for the vector4.

So here is what I did:

 var rotXcurve = new AnimationCurve();
 var rotYcurve = new AnimationCurve();
 var rotZcurve = new AnimationCurve();
 var rotWcurve = new AnimationCurve();

 var angle = Quaternion.Euler(0, 0, NeededRotation);

 rotXcurve.AddKey(Frame, angle.x);
 rotYcurve.AddKey(Frame, angle.y);
 rotZcurve.AddKey(Frame, angle.z);
 rotWcurve.AddKey(Frame, angle.w);

 clip.SetCurve(GO.name, typeof(Transform), "localRotation.x", rotXcurve);
 clip.SetCurve(GO.name, typeof(Transform), "localRotation.y", rotYcurve);
 clip.SetCurve(GO.name, typeof(Transform), "localRotation.z", rotZcurve);
 clip.SetCurve(GO.name, typeof(Transform), "localRotation.w", rotWcurve);

Hope t$$anonymous$$s will help anyone.

Instead, you can use the following property names to set the curve in euler angles like you were attempting to do originally.

localEulerAnglesRaw.x

localEulerAnglesRaw.y

localEulerAnglesRaw.z
