Unexplanable NullReferenceException Error
I am trying to make a 2D platformer and it is all working fine for now. However, I came across this random and mysterious error where I can't figure it out. Could someone explain to me why I have it and where is it causing it. I can't show the code since the error does not give the location. Here is the error:
NullReferenceException: Object reference not set to an instance of an object UnityEditor.Graphs.Edge.WakeUp () (at C:/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Edge.cs:114) UnityEditor.Graphs.Graph.DoWakeUpEdges (System.Collections.Generic.List`1[T] inEdges, System.Collections.Generic.List`1[T] ok, System.Collections.Generic.List`1[T] error, System.Boolean inEdgesUsedToBeValid) (at C:/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Graph.cs:387) UnityEditor.Graphs.Graph.WakeUpEdges (System.Boolean clearSlotEdges) (at C:/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Graph.cs:286) UnityEditor.Graphs.Graph.WakeUp (System.Boolean force) (at C:/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Graph.cs:272) UnityEditor.Graphs.Graph.WakeUp () (at C:/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Graph.cs:250) UnityEditor.Graphs.Graph.OnEnable () (at C:/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Graph.cs:245)
Hello! I also came across this problem and it was actually a serious problem. In the game menu I have the option to remove all sound effects via "Toggle". I have set a script for each new level to create one cloned enemy in more. In another script I store the data whether the sound effects in the game are on or off. I noticed that the cloned enemies still have a sound when "Toggle" is off, and I solved my problem like this:
using UnityEngine.UI;
using UnityEngine;
public class SoundEffectSaver: MonoBehavior
{
public Toggle toggleAudioChecker;
public Enemy [] _enemies;
public Crate [] _crates;
public void Start ()
{
toggleAudioChecker.isOn = PlayerPrefs.GetInt ("SaveBoolAudio")! = 0;
}
public void Update ()
{
_enemies = FindObjectsOfType <Enemy> ();
_crates = FindObjectsOfType <Crate> ();
PlayerPrefs.SetInt ("SaveBoolAudio", toggleAudioChecker.isOn? 1: 0);
int value;
value = toggleAudioChecker.isOn? 1: 0;
if (value == 1)
{
toggleAudioChecker.isOn = true;
GameObject.Find ("FlyFairy"). GetComponent <AudioSource> () .enabled = true;
foreach (Enemy enemy in _enemies)
{
enemy.GetComponent <AudioSource> () .enabled = true;
}
foreach (Crate crate in _crates)
{
crate.GetComponent <AudioSource> () .enabled = true;
}
}
else
{
toggleAudioChecker.isOn = false;
GameObject.Find ("FlyFairy"). GetComponent <AudioSource> () .enabled = false;
foreach (Enemy enemy in _enemies)
{
enemy.GetComponent <AudioSource> () .enabled = false;
}
foreach (Crate crate in _crates)
{
crate.GetComponent <AudioSource> () .enabled = false;
}
}
}
}
The original version was this:
using UnityEngine.UI;
using UnityEngine;
using UnityEngine.SceneManagement;
public class SoundEffectSaver: MonoBehavior
{
public Toggle toggleAudioChecker;
public void Start ()
{
toggleAudioChecker.isOn = PlayerPrefs.GetInt ("SaveBoolAudio")! = 0;
}
public void Update ()
{
PlayerPrefs.SetInt ("SaveBoolAudio", toggleAudioChecker.isOn? 1: 0);
int value;
value = toggleAudioChecker.isOn? 1: 0;
if (value == 1)
{
toggleAudioChecker.isOn = true;
GameObject.Find ("FlyFairy"). GetComponent <AudioSource> () .enabled = true;
if (SceneManager.GetActiveScene (). buildIndex> = 0 && GameObject.Find ("Monster") == true)

You came across "this" problem? How is your problem related to a null reference exception in Unity's internal editor Graph and Edge class? This doesn't seem to answer the question at all. You know this is a Q&A site, not a forum? The forum is over here, however I'm not sure your post would actually help anyone as your original code is horrible program$$anonymous$$g style and depends on countless hardcoded object names which is most likely the root cause of all your problems you may have had.
Hello! I am convinced that it will help many beginners like me. They should not put up with any problem, but look for a way to solve it. I succeeded and this annoying message no longer appears.
This seems to be an error inside of unity's assets You can't do anything about it but it shouldn't prevent the game from running fine.
