The name Flip and Horizontal does not exsist in the current context. pls help

How can I fix that they are existing?

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

public class PlayerController : MonoBehaviour {

public float WallDownForce;
public float speed;
public float jumpForce;
private float moveInput;

private Rigidbody2D rb;

private bool facingRight;

private bool isGrounded;
public Transform groundCheck;
public float checkRadius;
public LayerMask whatIsGround;

private bool onWall;
public Transform wallCheck;
public float WallCheckRadius;
public LayerMask whatIsWall;

private int extraJumps;
public int extraJumpsValue;

// Start is called before the first frame update
void Start() {
extraJumps = extraJumpsValue;
rb = GetComponent();
facingRight = true;
}

void FixedUpdate() {

Flip(Horizontal);

onWall = Physics2D.OverlapCircle(wallCheck.position, WallCheckRadius, whatIsWall);
isGrounded = Physics2D.OverlapCircle(groundCheck.position, checkRadius, whatIsGround);
moveInput = Input.GetAxis(“Horizontal”);
rb.velocity = new Vector2(moveInput * speed, rb.velocity.y);
}
void Update(){

if(isGrounded == true){
extraJumps = 1;
}
if(onWall == true){
extraJumps = 1;
}
if(Input.GetKeyDown(KeyCode.Space) && extraJumps > 0){
rb.velocity = Vector2.up * jumpForce;
extraJumps–;
}else if(Input.GetKeyDown(KeyCode.UpArrow) && extraJumps == 0 && isGrounded == true){
rb.velocity = Vector2.up * jumpForce;

if(Input.GetKeyDown(KeyCode.Space) && extraJumps > 0){
rb.velocity = Vector2.up * jumpForce;
extraJumps–;
}else if(Input.GetKeyDown(KeyCode.UpArrow) && extraJumps == 0 && onWall == true){
rb.velocity = Vector2.down * WallDownForce;
}
}
void Flip(float Horizontal)
{

if (Horizontal > 0 && !facingRight || Horizontal < 0 && facingRight)
{
facingRight = !facingRight;

Vector3 theScale = transform.localScale;

theScale.x *= -1;

transform.localScale = theScale;
}

}
}
}

Also, copy & paste the actual error, including line number.

Check your parenthesis. This is almost always caused by having too many and in the wrong place.

I believe it’s this line, Horizontal is not defined

Flip(Horizontal);

Try Flip(0);

and go from there. But please use code tags, I’m not sure but I believe Flip is improperly defined inside another method.

Yes. He’s defined it inside of the Update() method. Below is the code with the function moved outside of it.
