Start isn't starting when I hit play.

Hi, I’m new in Unity and basically I followed a tutorial and it all worked but now suddenly I hit play and I’ve got a null exception error because Node script isn’t Starting.
Here I have a debug that isn’t showing in the console:

using UnityEngine;
using UnityEngine.EventSystems;

public class Node : MonoBehaviour
{

    public Color hoverColor;
    public Color notEnoughMoneyColor;
    public Vector3 positionOffset;

    [HideInInspector]
    public GameObject turret;
    [HideInInspector]
    public TurretBlueprint turretBlueprint;
    [HideInInspector]
    public int isUpgraded = 0;

    private Renderer rend;
    private Color startColor;

    BuildManager buildManager;

    void Start()
    {
        Debug.Log("Nodo Start()");
        rend = GetComponent<Renderer>();
        if (rend != null)
        {
            startColor = rend.material.color;
        }
        else
        {
            Debug.LogError("Renderer not found on Node.");
        }

        buildManager = BuildManager.instance;
        if (buildManager == null)
        {
            Debug.LogError("BuildManager instance not found in Node.");
        }
    }

Then I use the rend to change de colour of the node:

 public void OnMouseEnter()
{
     if (EventSystem.current.IsPointerOverGameObject())
         return;

     if (buildManager == null)
     {
         Debug.LogError("BuildManager instance is null in OnMouseEnter.");
         return;
     }

     if (!buildManager.CanBuild)
         return;

     if (buildManager.HasMoney)
     {
         rend.material.color = hoverColor;
     }
     else
     {
         rend.material.color = notEnoughMoneyColor;
     }

}

public void OnMouseExit()
{
     rend.material.color = startColor;
}

But when I hit play it says null reference and I don’t see the Debug in the Start in the console.
The error code when I pass the mouse over the nodes is:

NullReferenceException: Object reference not set to an instance of an object
Node.OnMouseExit () (at Assets/Scripts/Node.cs:188)
UnityEngine.SendMouseEvents:smile:oSendMouseEvents(Int32)
The buildManager is called nice, I have an Debug in the Awake and it’s in the console when I test.

Anyone knows what’s happening?

Edit: The script was disabled in the inspector and that’s why the start wasn’t called.

This is for the scripting forum, not the job system.

Since the error seems to be in Node.OnMouseExit, it appears like rend is not set. Are you sure that there exists a Renderer component on the same GameObject as your script is on?

nvm, was my fault, the script was disabled in the inspector and of course it wouldn’t never start. Thanks!
