Adding State Machine Behaviour via Script C#

Unity Engine
1

How do I add a Behaviour to a State Machine?
I am using this:

AnimatorState newState = new AnimatorState();
newState.AddStateMachineBehaviour<StateScript>();

StateScript is my behavior script file.

Howerver I am getting this error:

AddAssetToSameFile failed because the other asset j is not persistent

Anyone knows why and how to solve it?

Thanks.

Did you ever figure this out ? same issue…
I assume its in editor script so the new state is not added to the parent asset as a permanent object, did you figure out how to ?

yeah exactly, newState is not persisted, normally you would add an AnimatorState into a controller which is persisted

take a look at this example

after adding an animator state you can add your state machine behaviour

Thanks.
Yeah figured it out… Need to use Animator.runTimeAnimatorControllor, then from there get the Asset from AssetDatabase, and can edit that.
UnityEditor.Animations.AnimatorController AnimContr = AssetDatabase.LoadAssetAtPath(AssetDatabase.GetAssetPath(MyAnimator.runtimeAnimatorController));
