Decreasing object size until a certain size over time?

Question

I want to decrease the size of an object in the y-axis slowly over time and until a certain scale. How can I do it? Thank you.

You should be able to set the local scale of the gameobject directly. So, a coroutine would do nicely do perform the task every frame, where it increasingly lowers the local scale.

E.g., something like this would work:

 IEnumerator shrinkObject(GameObject g, float scaleRate, float minScale)
 {
     float scale_y = g.transform.localScale.y;
     while(scale_y > minScale)    //    while the object is larger than desired
     {
         scale_y -= scaleRate * Time.deltaTime;    //    calculate the new scale relative to the rate
         Vector3 scale = g.transform.localScale;
         scale.y = scale_y;
         g.transform.localScale = scale;
         yield return null;    //    wait a frame
     }
     yield break;
 }

 public GameObject objectToScale;
 public float scaleSpeed;
 public float minSize;
 
     void Update()
     {
         if(objectToScale.transform.localScale.y <= minSize)
         {
                  objectToScale.transform.localScale = new Vector3(objectToScale.transform.localScale.x,objectToScale.transform.localScale.y + Time.deltaTime * scaleSpeed,objectToScale.transform.localScale.z)
         }
     }

You will have to do something close to that ^ some things might have to be changed (for example, if its a 2D game, it would use Vector2) Sorry for the short answer, have to go in a few mins. hope this helps you! Goodluck!
