Keyframe (AnimationCurve) won't update!

Hello, I have the following 2 values:

Code (CSharp):

1. Vector3[] pos;
2. AnimationCurve curveY;

In the Start method I set 10 keys in the animation curve

Then in a for loop, I am trying to update update those keys with the new position

Code (CSharp):

1. for(int i=0; i<complexity; i++){
2.     curveY.keys[i].value = pos[i].y;
3.     Debug.Log(curveY.keys[i].value +", "+ pos[i].y);
4. }

However, the debug shows the pos is constantly changing, but the curveY never changes! It always stays at the exact same value that was set in at the beginning.

I even tried this way but it doesn't work either!

Code (CSharp):

1. for(int i=0; i<complexity; i++){
2.     curveY.keys[i] = new Keyframe(curveY.keys[i].time, pos[i].y);
3.     Debug.Log(curveY.keys[i].value +", "+ pos[i].y);
4. }

Any ideas?

Note that the array is "by value", i.e. getting keys returns a copy of all keys and setting keys copies them into the curve.

You can't just modify curve.keys[0] because that is not the key in the curve
get the whole array (copies by value), modify that, then set the whole array

 

Problem is there doesn't seem to be a way to set the array aside from creating a new animation curve.

However I found a solution that works, which involves having my own array of keys, modifying that, and then using the curve's built in function to adjust an existing key.

Code (CSharp):

1. keysY[i].value = pos[i].y;
2. curveY.MoveKey(i, keysY[i]);

 

except for curve.keys = myKeys ...?
