How to rotate object based on cursor position

Questions & Answers
1

I want to create an AirStrike ability for a RTS game. Before the planes launch, I want to set the position and rotation of the “Strike Zone”. I have this code, where I can rotate the object, but not on the mouse position.

Here is the code:
public class AirStrikeAbility : MonoBehaviour
{
public float rotSpeed = 20;

public GameObject camera;
public bool mousePressed = false;

// Update is called once per frame
void Update()
{
    if (mousePressed == true)
    {
        camera.GetComponent<RTSCameraController>().enabled = false;
    }
}

private void OnMouseDown()
{
    mousePressed = true;
}

private void OnMouseDrag()
{
    float rotX = Input.GetAxis("Mouse Y") * rotSpeed * Mathf.Deg2Rad;
    transform.RotateAround(Vector3.up, -rotX);
}

private void OnMouseUp()
{
    mousePressed = false;
    camera.GetComponent<RTSCameraController>().enabled = true;
}

}
