Tank tutorial issue: No MonoBehaviour scripts in the file...

Unity Engine
1

I’m doing the Tank tutorial:

I am at the point (time stamped in URL) where you take the C# assets code and drag it into the tank but I keep receiving the error "can’t add scrript behaviour AuthorityOnSpawnedObjectsIsCorrect. The script needs to derive from MonoBehaviour.

I keep reading the file name and public class need to match, which they do. This is also the default files from the tutorial provided. I see others having this issue but I have not had a case where it is solved yet.

Here is the file:

(File name is “TankMovement”)

I also tried changing it to “TankMovement.cs”

using UnityEngine;

public class TankMovement : MonoBehaviour
{
    public int m_PlayerNumber = 1;        
    public float m_Speed = 12f;           
    public float m_TurnSpeed = 180f;      
    public AudioSource m_MovementAudio;   
    public AudioClip m_EngineIdling;      
    public AudioClip m_EngineDriving;     
    public float m_PitchRange = 0.2f;

    /*
    private string m_MovementAxisName;    
    private string m_TurnAxisName;        
    private Rigidbody m_Rigidbody;        
    private float m_MovementInputValue;   
    private float m_TurnInputValue;       
    private float m_OriginalPitch;        


    private void Awake()
    {
        m_Rigidbody = GetComponent<Rigidbody>();
    }


    private void OnEnable ()
    {
        m_Rigidbody.isKinematic = false;
        m_MovementInputValue = 0f;
        m_TurnInputValue = 0f;
    }


    private void OnDisable ()
    {
        m_Rigidbody.isKinematic = true;
    }


    private void Start()
    {
        m_MovementAxisName = "Vertical" + m_PlayerNumber;
        m_TurnAxisName = "Horizontal" + m_PlayerNumber;

        m_OriginalPitch = m_MovementAudio.pitch;
    }
    */

    private void Update()
    {
        // Store the player's input and make sure the audio for the engine is playing.
    }


    private void EngineAudio()
    {
        // Play the correct audio clip based on whether or not the tank is moving and what audio is currently playing.
    }


    private void FixedUpdate()
    {
        // Move and turn the tank.
    }


    private void Move()
    {
        // Adjust the position of the tank based on the player's input.
    }


    private void Turn()
    {
        // Adjust the rotation of the tank based on the player's input.
    }
}

How can I have this working? I really want to finish this

Do you have any red compiler errors in your console? This will prevent new scripts from doing anything, including detecting monobehaviours.

If that’s not it, try creating a new script called TankMovement, copy & paste the code from your script that wasn’t working, then delete the script that wasn’t working.

If that still doesn’t do it, try the previous step again, but with a different filename for the script, and change the class name to match it.

Good luck!
