I need help

Hello i am Programming a simple 2D game for mobile devices with 2 Joysticks one for the rotation for the char and the other one for the movement i made a simple script for the rotation. But every time i start the game there is some wierd looking black line on the Screen.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Movement : MonoBehaviour
{
public float moveSpeed = 5f;
public Joystick Joystickmovement;
public Rigidbody2D rb;
public Joystick Looking;
Vector2 Rotation;
Vector2 movement;
public Rigidbody2D Kamera;

// Update is called once per frame
void Update()
{
//Input
movement.x = Joystickmovement.Horizontal;
movement.y = Joystickmovement.Vertical;
Rotation.y = Looking.Horizontal;
Rotation.x = Looking.Vertical * -1;

}

void FixedUpdate()
{
//movement
rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);

//Rotation
Vector2 VirtualMouse = rb.position + Rotation;
Vector2 lookdir = VirtualMouse - rb.position;
float angle = Mathf.Atan2(lookdir.y, lookdir.x) * Mathf.Rad2Deg - 90f;
rb.rotation = angle;
Kamera.position = rb.position;
}
}

 

i think it is related because the render issue started when i implemented the Rotaiton

 

Have you tried disabling this script to see if it's really the culprit?

 

Yes the little line is not there if i disable the script
movement.x = Joystickmovement.Horizontal;
movement.y = Joystickmovement.Vertical;
Rotation.y = Looking.Horizontal;
Rotation.x = Looking.Vertical * -1;
this is the part where i get the input from the joysticks

//Rotation
Vector2 VirtualMouse = rb.position + Rotation;
Vector2 lookdir = VirtualMouse - rb.position;
float angle = Mathf.Atan2(lookdir.y, lookdir.x) * Mathf.Rad2Deg - 90f;
rb.rotation = angle;
this is the part where i first calculate a virtual mous to get the location from the joystick then i calculate the angel and then set the angel as the Rigidbody2D rotaiton -90°
