How to move an object from point to point?

Question

Unity

Here is my code how to make an object move back and forth indefinitely

public class MoveEnem : MonoBehaviour
{
    public Vector2 startPos;
    public Vector2 endPos;
    public float step;
    private float progress;
    void Start()
    {
        transform.position = startPos;
    }

   
    void Update()
    {
        transform.position = Vector2.Lerp(startPos, endPos, progress);
        progress += step;
        
        
    }
}

Answer 1

You need to loop progress. For example, you can do it like this:

transform.position = Vector2.Lerp(startPos, endPos, 0.5f+0.5f*Mathf.Sin(progress));
