Question Trying to manipulate animation clips's Keyframes using scripts.

Hi everyone,
I have some simple animations for a 2D project. My intention with my animation clip is to take my current GameObject and translate it up / sideways / etc. The tricky part where I couldn't find a solution : how to make this translation happen relative to the GameObject's current position?

For example, if I have an object with anchoredPosition.y=20, I want to move it to 30 = (anchoredPosition.y + 10).

Here's some code I wrote after digging around. It produces the desired effect for editing the animation clip, based on manual testing by changing Animator parameters in the Animator editor/inspector.

However, after these script edits, the Animator component seems to be ignoring my calls to SetBool. Previously, I used the SetBool call to change states, which will then play the clip that I am editing in my script.

After adding the below code, SetBool and GetBool on my animator returns True in logs, but my Animator inspector page still shows False.

Code (CSharp):

1.  
2. Animator anim = GetComponent<Animator>();
3. // Iterate over clips, looking for the clips I want to edit by name string.
4. foreach (AnimationClip clip in anim.runtimeAnimatorController.animationClips)
5. {
6.   Keyframe[] keys = new Keyframe[2];
7.   AnimationCurve curve;
8.   if (clip.name == nameOfClipToModify)
9.     {
10.        // Set up a new curve for AnchorPos.y with my desired relative values.
11.        keys[0] = new Keyframe(0.0f, relativeStart);
12.        keys[1] = new Keyframe(0.6f, relativeEnd);
13.        curve = new AnimationCurve(keys);
14.        // clip.legacy = true;  Setting this did not matter
15.        clip.SetCurve("", typeof(RectTransform), "m_AnchoredPosition.y", curve);
16.     }
17. }
18.  

If I omit this code, SetBool works and triggers the animation clip (although with absolute parameters for anchor position).

Let me know what I can do (or if there's an easier way to make animations move relative to an existing position). Thanks
