[Solved] Instantiate Object on Raycast2D hit and rotate Instance

I want to move an instance of a gameObject along the outline of another gameobject. Its a 2D Project in Unity.
My current Code:

Code (CSharp):

1. Vector3 mousePosition = m_camera.ScreenToWorldPoint(Input.mousePosition);
2.     RaycastHit2D hit = Physics2D.Raycast(new Vector2(mousePosition.x, mousePosition.y), new Vector2(player.transform.position.x, player.transform.position.y));
3.     if (hit.collider != null &&  hit.collider.gameObject.tag == "Player") {
4.         if (!pointerInstance) {
5.             pointerInstance = Instantiate(ghostPointer, new Vector3(hit.point.x, hit.point.y, -1.1f), Quaternion.identity);
6.         } else if(pointerInstance) {
7.             pointerInstance.gameObject.transform.position = new Vector3(hit.point.x, hit.point.y, -1.1f);
8.             pointerInstance.gameObject.transform.eulerAngles = new Vector3(0f, 0f, hit.normal.x);
9.         }
10.  
11.     }

Unfortunately, the gameObject doesn't rotate towards the mouse and the position on the left side of the playerObject is also sometimes off. I tried to use Instantiate() with Quaternion.LookRotation(hit.normal), but no luck either.

Here a rough sketch of what I want to achieve:


Any help is appreciated. Thanks!

 

Thank you! In the meantime, I found a workaround but this information is definitely helpful for future projects.

I also learned that it's better to use Mathematical way instead of a physical way(Raycasting) because in raycasting you have to throw ray several time for checking hit point, it could make your game lag.
