anchoredPosition in mechanim locks my axis

Question

Hello,

I have a UI Text object. I affect it in several ways:

I move it down with mechanim affecting its pivot
I scale is up and down several times using mechanim affecting it's scale

I shake it (move it inside unitSphere on y/x axis) with the below script

  void Update () 
     {
         ShakeStandBy ();
     }
 
     void ShakeStandBy()
     {
         if(shakeIntensity > 0)
         {
             transform.position = originalPosition + Random.insideUnitSphere * shakeIntensity;
             shakeIntensity -= shakeDecay;
         }
         else
         {
             transform.position = originalPosition;
         }
     }

"1.", "2." and "3." all work fine on their own.

Here's the problem: In "2." I also need to affect the anchoredPosition because by that time the text is moved with "1." and its pivot is modified, so to counter that I also affect anchoredPosition in my scaling animation which gives the desired effect - the text is scaled from its CENTER and remains in the desired location. If I were to counter this effect by affecting pivot instead, the scaling would not happen from the center but from the top (since I moved the Text DOWN).

As soon as I use anchoredPosition in my animation, the shake stops working on the y axis as if it's locked and only works on x axis. I don't even have to run that animation, it's sufficient to have a state in the animator with this animation (that affects anchoredPosition somehow) plugged in, and the shake won't work. If you unplug it, it's works normally again.

I tried rewriting the shake function with GetComponent().anchoredPosition but I get the same result. I spent the entire day trying various workarounds and nothing solves this issue.

Does anyone know why do I get such behaviour?

Thanks in advance.

Yup, mecanim just works this way, move your ShakeStadBy() call to LateUpdate instead of regular Update. I fixed my animation problems this way. And this maybe interesting: http://docs.unity3d.com/Manual/ExecutionOrder.html This is for 2) and 3).

For 1) and 2) you can also try using animation layers and play with override value.

You know what the funniest thing is? I have that picture of the execution order on my desktop for 3-4 months already. And I got so used to it being there that I stopped perceiving that it actually holds any kind of information and by the gods man did you save me a lot of further guesswork.

Thank you!

Still, It's very weird and uncomfortable that if I have ANY animation in mechanim affecting ANYTHING, that THING will be locked in place and I won't be able to manipulate it unless it's in LateUpdate and sometimes I even have to manually disable the animator so it doesn't snap the position/scale/whatever back to it's place as soon as the action in LateUpdate is finished. It looks like a bug. I mean if the animation is not playing at that moment, why the hell are its values (whatever it animates) locked in place?? This looks like a bug to me
