public static void SetObjectReferenceCurve(AnimationClip clip, EditorCurveBinding binding, ObjectReferenceKeyframe[] keyframes);


clip The animation clip to modify.
binding The bindings that define the paths and the properties of each curve.
keyframes Array of Object reference values over time. Setting this to null will remove the curve.


Adds, modifies, or removes an object reference curve in an animation clip.

Unity has two types of animation: float curve and object reference curve. A float curve is a classic curve that animates a float property over time. An object reference curve is a construct that animates an object reference property over time.

This method modifies object reference curves. For float curves, see AnimationUtility.SetEditorCurve.
