As you see, the line renderer behaves in a very strange way.
I want that the line renderer middle point be attached like to the mouse position.
I hope someone could show me the problem. Here is the code:

public class Bow : MonoBehaviour {

    public GameObject line;
    public float maxStretchDistance;
    float currentStretchDistance;
    Vector3 mousePosition;
    Vector3 bowDirection;
    Vector3 mousePositionInRelationToLineCenter;

    void Update() {
        mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition) + Vector3.forward * 10;
        mousePositionInRelationToLineCenter = mousePosition - line.transform.position;
    }

    void OnMouseDrag()
    {
        bowDirection = -(mousePosition - this.transform.position);
        bowDirection.Normalize();
        transform.right = bowDirection;
        line.GetComponent<LineRenderer>().SetPosition(1, mousePositionInRelationToLineCenter);
    }

    void OnMouseUp()
    {
        line.GetComponent<LineRenderer>().SetPosition(1, Vector3.zero);
    }

}

Thank you in advance

Without reading the code, it seems you have a frame issue. Is the string a child of the bow? Because the bow is rotating correctly, and the string is behaving as if the rotation angle is doubled.
