How do i create a sprite sheet animation by script without the UnityEditor classes

Hello guys,

I have this function that i use to create a sprite sheet animationClip at runtime. The problem is EditorCurveBinding, ObjectReferenceKeyframe, AnimationClipSettings and AnimationUtility are UnityEditor classes and cannot be used in the built version. i have searched all arount the web for a built version alternative but to no avail.

Does anyone have any idea about how to make this work for a built version?

Here is my function:

 public static AnimationClip CreateAnimationCLip(string name, int frameRate, bool isLooping, string spritesPath, bool isLegacy = false)
         {
             AnimationClip animationClip = new AnimationClip();
             animationClip.name = name;
             animationClip.frameRate = frameRate;
             animationClip.wrapMode = WrapMode.Loop;
             animationClip.legacy = isLegacy;
             EditorCurveBinding spriteBinding = new EditorCurveBinding();
             spriteBinding.type = typeof(SpriteRenderer);
             spriteBinding.path = "";
             spriteBinding.propertyName = "m_Sprite";
 
             Sprite[] idleSheet = Resources.LoadAll<Sprite>(spritesPath);
             ObjectReferenceKeyframe[] spriteKeyFrames = new ObjectReferenceKeyframe[idleSheet.Length];
             for (int i = 0; i < idleSheet.Length; i++)
             {
                 spriteKeyFrames[i] = new ObjectReferenceKeyframe();
                 spriteKeyFrames[i].time = i / animationClip.frameRate;
                 spriteKeyFrames[i].value = idleSheet[i];
             }
             AnimationClipSettings animClipSett = new AnimationClipSettings();
             animClipSett.loopTime = true;
             AnimationUtility.SetAnimationClipSettings(animationClip, animClipSett);
 
             AnimationUtility.SetObjectReferenceCurve(animationClip, spriteBinding, spriteKeyFrames);
 
             return animationClip;
         }
