Help with some code (mouse directional targeting)

SO im trying to have a target follow a mouse around my player
Similar to this:

i even tried to copy his code, my issue is i cannot get the target to rotate around the player, its sorta stuck rotating somewhere else and then when i move my player the target starts to move across the screen really fast.

my code:

Code (CSharp):

1.     private float Radius = .24f;
2.     private float angle;
3.     private Vector3 v3pos;
4.    
5.     void FixedUpdate () {
6.         GameObject player = GameObject.Find("Player1");
7.        
8.         v3pos = Input.mousePosition;
9.         v3pos.z = (player.transform.position.z - Camera.main.transform.position.z);
10.         v3pos = Camera.main.ScreenToWorldPoint(v3pos);
11.         v3pos = v3pos - player.transform.position;
12.  
13.         angle = Mathf.Atan2(v3pos.y, v3pos.x) * Mathf.Rad2Deg;
14.  
15.         if (angle < 0.0f) angle += 360.0f;
16.         transform.localEulerAngles = new Vector3(0,0, angle);
17.  
18.         float xpos = Mathf.Cos(Mathf.Deg2Rad * angle) * Radius;
19.         float ypos = Mathf.Sin(Mathf.Deg2Rad * angle) * Radius;
20.  
21.         transform.localPosition = new Vector3(player.transform.position.x + xpos * 2, player.transform.position.y + ypos * 2, 0);
22.  
23.     }

 

I figured it out just now, it was the final tranform.localposition i changed it to transform.position and now it works.

EDIT: well it sorta works, it ever so slightly moves the target a little off while my character is moving, its barely noticeable tho.
