I'm Making A Unity Game and Adding Controller Support so I'm making a variable to add my controls class but I get an error

Question

I'm following a tutorial to add controller support to my game (This One) but when I save my script I get this error:

Assets\Scripts\PlayerMovement.cs(9,5): error CS0246: The type or namespace name 'PlayerControls' could not be found (are you missing a using directive or an assembly reference?)

Some how it even worked in another Unity project!?

using UnityEngine;
using UnityEngine.InputSystem;

public class PlayerMovement : MonoBehaviour
{

    public Rigidbody rb;

    InputMaster controls;

    public float Force = 2000f;
    public float leftrightForce = 500f;

    void Awake()
    {
        controls = new PlayerControls();

        controls.Gameplay.Move_Left.performed += Left();

        controls.Gameplay.Move_Right.performed += Right();
    }
    
    void FixedUpdate()
    {
        rb.AddForce(0, 0, Force * Time.deltaTime);   //Makes Cube Go Vroom-Vroom

        if (rb.position.y < -1.47)
        {
            FindObjectOfType<GameManager>().EndGame();
        }
    }

    void Left()
    {
        rb.AddForce(leftrightForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }

    void Right()
    {
        rb.AddForce(-leftrightForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }

    void OnEnable()
    {
        controls.Gameplay.Enable();
    }

    void OnDisable()
    {
        controls.Gameplay.Disable();
    }
}

If you know how to help please help!

Answer 1

instead of using ranndom.choice, maybe use pop and shuffle:

list_ = ["apple", "orange", "banana"]
new_list= list_[:]
random.shuffle (new_list)
for i in range(3):
    print(new_list.pop())

Answer 2

You can use random.sample with k=len(list_) to create a new list that has been shuffled:

>>> random.sample(list_, k=len(list_))
['banana', 'apple', 'orange']
