Changing enum state via another script

Question

Hello,

I've been struggling in these forum / answers for an answer to this for a couple of hours now but nothing seems to work for me for some reason. Even though some answer sound logical, I can't make it work.

Here's my code, which based of some other answer, should work:

Separate Script for the enum

 public enum CharacterState
 {
     Walking,
     Dialog,
     Combat
 }

CharController Script

 public class mCharWorld : MonoBehaviour
 {
 
 public CharacterState CharState;

 void Start()
 {
     CharState = CharacterState.Walking;
 }

 void Update()
 {
     if (CharState == CharacterState.Walking)
     {
          debug.log("Something");
     }
 }

 }

In Another Script

 public mCharWorld mCharScript;

 public void InitializeDialog()
 {
     mCharScript.CharState = CharacterState.Dialog;
 }

This last script only throw the classic exception "NullReferenceException: Object reference not set to an instance of an object".

Not sure how it can be null at this point as it would work for any other type of variable.

A bit of help would be appreaciated.

Best regards,

Stupid mistake: It was just not initialized when I though it was done. For those who would get something similar:

 mCharWorld mCharScript;

 void Start(){
      mCharScript = GameObject.Find("MainChar").GetComponent<mCharWorld>();
 }

 void WhatEver(){
     mCharScript.CharState = CharacterState.Dialog;
 }

EDIT: You can also obviously make the variable "public" and attach it in the editor for more performance depending on your needs.
