Getting turning direction for character without using Input

Found the answer, here it is if anyone is interested:

 function Start () {
     lastFrameAngle = actorParent.eulerAngles.y;
 }
     
     
 function CalculateDirection(){    //running it on Update
     var currentFrameAngle : float = actorParent.eulerAngles.y;
     angleDifference = currentFrameAngle - lastFrameAngle;
  
     lastFrameAngle = currentFrameAngle; 
 }
