How to check if my ball stopped rolling?

I want to check when my ball stopped rolling (moving) for more then 5 seconds and then execute some code. I'm working on an android game and sometimes the ball gets stuck, the ball should be moving constantly so I want to check if it's moving and if it's not I need to respawn it.

What is the best way to do this?

Put this as a C# script component onto your ball gameobject.

    public class MyBall : MonoBehaviour{
       private Transform _myTransform = null;
       private Vector3 _lastPosition = null;

       private void Awake(){
          _myTransform = transform;
          _lastPosition  = _myTransform.position;
       }

       private void Update(){
          if(_lastPosition == _myTransform.position){
             Debug.Log("Did not move");
          }else{
             Debug.Log("Moved");
          }
          _lastPosition = _myTransform.position;
       }
    }

You can create a simple counter for count 5 seconds and check the gameObject.getComponent.velocity.magnitude;

And create a if and check this magnitude is smaller than your wanted level

Each time Update is called, you could check the magnitude of the object's velocity. If it's lower than a small amount (say 0.1 or something depending on your game's scale), add Time.deltaTime to a member variable, otherwise, set that variable to 0. If that variable is ever over 5, you know your object has been not moving (or close) for 5 seconds. Then execute your code.
