So i tried to implement a script that changes level when you reach a certain goal in the previous one, but the level just wont load. here are the screenshots of what happens.
![alt text][1]
![alt text][2]
Also an error alert comes up saying that the there's a nullreferenceexption in my Soundmanager script, here's the script.
public class SoundManager : MonoBehaviour {
public static SoundManager Instance = null;
//inizializzatore per nuovo soundmanager
//inizializzatore variabili dei suoni
public AudioClip jump;
public AudioClip getCoin;
public AudioClip rockSmash;
public AudioClip mannyDies;
public AudioClip click;
public AudioClip NewGameClick;
public AudioClip EnemyDies;
public AudioClip win;
private AudioSource soundEffectAudio;
void Start () {
//per fare in modo che nessuno possa creare un nuovo suondmanager
if (Instance == null)
{
Instance = this;
}
else if (Instance != this)
{
Destroy(gameObject);
}
AudioSource theSource = GetComponent();
soundEffectAudio = theSource;
}
public void PlayOneShot(AudioClip clip)
{
soundEffectAudio.PlayOneShot(clip);
//says that the error is here!
}
}
I would be very thankful if you could help me

Unity 5 scene next level scene wont load properly

Can't drag variables between different scenes
Hi, I'm having an issue with SceneManager.LoadSceneAsync(scene, LoadSceneMode.Additive)
I have a "Player Scene" which contains my Player, along with any managers for score, inventory ect.
But, when a new scene gets loaded additively, all references to the Player are missing, and I cannot drag the references from the Player because it is in it's own separate scene.
Originally, I had a clone of the Player in each separate scene, and I could just assign the variables from that Player, but now I want the Player to be persistent between scenes, so I removed the Player from all scenes besides the "Player Scene", but now all other scenes have "Missing reference exceptions". What is the solution to this?
Any help is greatly appreciated! thanks.

Mob AI not immediately finding object it is looking for, and crashing when it eats food?
So I have a mob AI script that I am using on a slime model, but the problem is that I'm using Physics.OverlapSphere to find things eligible to eat, and it is picking up the terrain for most of its objects even though the terrain is only one thing, and it takes between 1-60 seconds to replace the gameobject that it has eaten with a new target, and sometimes it will crash due to its targeted food object being eaten by another slime. Any help on how to get it to not pick up the terrain as well as not crash when the food does not exist would be greatly appreciated.

if (Something != null) not good enough
Hello, it seems that I have been having a problem multiple times where I might have a GameObject variable called "Target" which may or may not exist, so I first check by doing:
if (Target != null){
//Something that requires Target to not be null will happen;
}
This is apparently not good enough though, because my game will randomly crash sometimes when apparently my check is ignored, and I get this error:
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

gameobject has been destroyed you are still trying to access it
im getting this message and im sure its because when my player gets hit he loses all his gems, the gems flash and then there destroyed, following this message i get an odd message about matrix stack full depth reached but i cant see how theyre related, any how im instantiating a prefab making it flash using materials for a couple seconds and then destroying themso my error is because the flashing is still happening after there destroyed but i am already checking if the gameobject is null can anybody give me a hand? here is half the code to make the gems flash
void coinFlash()
{
newCoins = GameObject.FindGameObjectsWithTag("newcoins");
if (newCoins != null)
{
for (var i = 0; i < newCoins.Length; i++)
{
//coinPrefab.GetComponent().sharedMaterial.color = new Color32(250, 250, 210, 0);
coinPrefab.GetComponent().sharedMaterial = goldtrans;

Destroying GameObject while in Inspector = MissingReferenceException
I have a behaviour that just acts as a data container that's on one of my models.
If I select that game object so that the script is displayed in the behaviour, and tweak the model import settings and click "Apply" I get an error (thrown repeatedly until I make the inspector focus on another object).
MissingReferenceException: The object of type 'MyComponent' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Now, my asset processor is updating a prefab, copying that component, and then calling DestroyImmediate, which I'm sure is why the error is being generated.
However, I can find no way to protect against this.
Perhaps some way to just clear the selected object so that the inspector isn't on it?

Each bullet forms clone of the last
Hi, firstly I am relatively new to unity and C# in general but I am trying to create a simple 3D ball rolling platform game with a turret that shoots the player.
Currently the turret will wake up once the player is within shooting range and continue to shoot cannonballs are regular intervals. However, each cannonball forms a clone of the last one fired so it shows this in the hierarchy;
cannonballs(clone)
cannonballs(clone)(clone)
cannonballs(clone)(clone)(clone)
cannonballs(clone)(clone)(clone)(clone)
etc.
http://imgur.com/OSFP8BE
I created a cannonball destroy script to remove the cannonball clones from the game after a set amount of time and attached this script to the cannonballs prefab as seen here;

Destroy(gameObject, DeathTime);

However, with this script in place a new error appears in the console each time the turret tries to shoot a cannonball;
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

As far as I understand, it appears to be destroying the prefab instead of the cannonball clones?? I am not sure what I am doing wrong here and any help would be greatly appreciated. I have tried incorporating the destroy game object into the main turretAI script and I have tried destroying the gameobject by name instead but I have had no luck and I am very confused.
Here is the main turretAI script;
public class TurretAI : MonoBehaviour
{
//floats
public float distance;
public float wakeRange;
public float LastShotTime = float.MinValue;
public float fireRate;
//turretspin
public float turretSpeed;
//booleans
public bool awake = false;
//references
public GameObject Cannonballs;
public Transform target;
public Animator anim;
public GameObject BulletSpawn;
void Awake()
{
anim = gameObject.GetComponent();
}
void Update()
{
anim.SetBool("Awake", awake);
RangeCheck();
if (awake)
{
{
//Rotate turret to look at player.
Vector3 relativePos = target.position - (transform.position);
Quaternion rotation = Quaternion.LookRotation(relativePos);
rotation.x = 0;
rotation.z = 0;
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * turretSpeed);
}
}
//fire rate
if (distance < wakeRange && Time.time > LastShotTime + (3.0f / fireRate))
{
LastShotTime = Time.time;
launchBullet();
}
}
void launchBullet()
{
Cannonballs = Instantiate(Cannonballs, BulletSpawn.transform.position, BulletSpawn.transform.rotation) as GameObject;
Cannonballs.GetComponent().AddForce(transform.forward * 500);
}
void RangeCheck()
{
distance = Vector3.Distance(transform.position, target.transform.position);
if (distance < wakeRange)
{
awake = true;
}
if (distance > wakeRange)
{
awake = false;

Unknown problem with MissingReferenceException
Ok, so my code is only this:
#pragma strict
var speed : float;
var rb : Rigidbody2D;
function Start () {
rb = GetComponent(Rigidbody2D);
}
function Update () {
rb.velocity.y = Input.GetAxis("Vertical") * speed;
}
My scene has only one sprite(with rigidbody2D) & the camera.
This is the error I get. What's going on?

Texture2D variable causes MissingReferenceException
I've suffered a MissReferenceException when using Texture2D. With below code,
public abstract class TestBase
{
protected readonly Texture2D texture;
public TestBase()
{
texture = new Texture2D(100, 100, TextureFormat.RGB24, false);
}
public abstract void UseTexture();
}
public class Test : TestBase
{
public Test () : base()
{
}
public override void UseTexture()
{
// others
texture.Resize(80, 80);
// others code
}
}
public class TestWindow : EditorWindow
{
private static TestBase base;
[MenuItem("Tools/Test")]
private static void Init()
{
// Initialization
}
public void OnGUI()
{
if (base == null)
{
base = new Test();
}
base.UseTexture();
}
public void OnDestroy()
{
// others
Resources.UnloadUnusedAssets;
}
}
we can get a Editor Window. With the steps below, I can get MissingReferenceException, and the "texture" will be "null".
1. The "TestWindow" will be opened automatically at Play Mode;
2. Exit Play Mode, the "TestWindow" will be closed automatically;
3. Open the window from the Menu, then the Exception occurs.
Someone told me that set the hideFlags of Texture2D to be "DontSave", such as:
public abstract class TestBase
{
...
public TestBase()
{
texture = new Texture2D(100, 100, TextureFormat.RGB24, false)
{
hideFlags = HideFlags.DontSave
};
}
...
}
The error is fixed. But I cannot actually get why.
Could someone explain it?
Thanks

Missing built in enum reference?
Hello,
I am trying to figure out why my build will not compile. I am getting the Error CS0246 saying I am missing an assembly or reference for 'NetworkDisconnection' which is a built in Unity enum. In the code I have the using UnityEngine and using System.Collections, which I know the 'NetworkDisconnection' enum is a part of. Any clue how to fix? This is the code that is throwing the error

MissingReferenceException on Inspector-assigned values after reloading scene
I have a level scene where gameplay takes place. In this scene, I have a canvas.
I also have a PlayerGUI (manager object) that has Inspector-assigned references to the canvas elements it needs to enable/disable depending on the gameplay state.
I enter the scene in gameplay and press the pause button to bring up the pause UI (PlayerGUI calls the SetActive(true) method on the GameObject reference to the panel of the pause UI).
I then reload the scene using SceneManager.LoadScene, and try to open the pause UI again. This time, I'm given an exception:
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
The exception points to this line:
PanelPauseMenu.SetActive(true);
I am almost certain this has to be a bug in Unity. When checking the Hierarchy during gameplay, PlayerGUI has a live reference to the correct element (the reference can be double clicked, and the live, correct UI element is highlighted).
Does anyone have any idea why this happens? Everything works fine the first time around, but completely fails if the level is loaded again -- it's like the references aren't updated when the level is reloaded, although they appear correct in the Inspector.

Can I check if this.gameObject was destroyed?
Here's a simple version of a coroutine that's running on one of my objects:
public IEnumerator PulseOnGround()
{
while (gameObject.activeInHierarchy)
{
//do stuff
yield return new WaitForFixedUpdate();
if (gameObject == null) yield break;
}
}
This throws a MissingReferenceException when the object is destroyed from another script. It appears that the script keeps running after it's destroyed, but I can't find a way to check if the gameObject still exists from within the script.
Is it possible to break this coroutine on destroy from within this script, without using StopCoroutine? Or do I need another script to keep track of whether this script is still alive and call StopCoroutine on any coroutines that might still be running?
I'm trying to do this without StopCoroutine because I don't have references to every coroutine that's running, and I would want all of them to stop on destroy anyway.

OnBecameInvisible() Throwing error when game stops
Hello, I tried and searched but did not found any solution to my problem. I call OnBecameInvisible() function from few different scripts. All of them are throwing errors. First one is this part of code:
void OnBecameInvisible(){
if (transform.position.x < Camera.main.transform.position.x) {
//do stuff
}
}
It says "Assertion failed on expression: 'go.IsActive() && go.GetTag() != 0'". This happens only when I exit play mode.
And there is another error on second line of this code:
void OnBecameInvisible(){
if (transform.position.x < playerTransform.position.x) {
//do stuff
}
}
It says: "MissingReferenceException: The object of type 'Transform' has been destroyed but you are still trying to access it." It happens whenever I exit the play mode. I had my Scene tab closed but nothing.
What should I do?

Assigned variable returns null?
I have what I believe to be a very straightforward script that effectively just enabled gameobjects in the scene when certain actions are completed. I'm running into an issue where when i try to enable them they will occasionally evaluate to null and I will hit a missing reference exception as if the object has been deleted - but if i look at the object in the inspector I can see that it is definitely assigned (its a public variable.)
stuff I've tried:
- I made sure there isn't another instance of this class in the scene that hasn't been initialized properly. there is only one instance, and I can see that its gameobjects are assigned as anticipated.
- Reassigning the game objects at runtime. I figured maybe something was weird about how they were assigned, so I tried assigning them manually at run time in the inspector but no joy, it still gives me a missing reference exception
- Manually enabling it before trying to reference it. I figured maybe something weird could be happening where its having trouble retrieving a disabled gameobject but that still gave me a missing reference exception.
I'll post the code thats enabling it below as well as what it looks like in the inspector but its really about as straightforward as it gets, maybe I'm missing something very simple though.
Things that might make this weird :
- This class and the objects its enabling are loaded into the scene via asset bundle. unity has historically had some weirdnesses associated with loading asset bundles so maybe theres a bug to do with that in play?
- the function gets called as the result of an event being fired elsewhere. I'm not sure why this would matter since it doesnt seem like its a problem with the wrong function being called/the wrong parameter being passed but ive had troubled with events and listeners before.
any help would be appreciated.

GameObject not in hierarchy missing reference to a script
I have a project in 5.5 beta that has a scene which has a ghost object. it does not show up in the editor hierarchy however if i double click the warning (missing script reference) the scene editor find an object called "GameDrawManager". which is not part of any prefabs nor is it part of the scene what so ever.
even after deleting all objects in the scene, at run time there would be an empty hierarchy yet it still gives me the warning. I can also click on the warning which takes me to said invisible object. which is only a transform and a missing behaviour.
i managed to get rid of it by creating a new scene and pasting all of the world objects to it

MissingReferenceException: The object of type 'Animator' has been destroyed but you are still trying to access it.
Hi all. I know many other have already asked this kind of question, but still I haven't found an answer which worked for me.
The issue is:
My game has 2 scenes so far: a **Main Menu** and a **Level 1**.
Normally, when my character dies in the game, she just respawns at the latest checkpoint.
But if I load Level 1 from the Main Menu, when she dies she respawns already dead with the Player Controller script disabled and I get this error:
*"MissingReferenceException: The object of type 'Animator' has been destroyed but you are still trying to access it."*
With "already dead" I mean that she gets stuck in the dead animation and the input doesn't work. I guess the input doesn't work because one of the scripts is disabled. And she gets stuck in the animation because the controller is destroyed.
But what confuses me is that this happens only when playing this level loaded from the Main Menu.
This is the code that runs when she dies:
**PLAYER CONTROLLER SCRIPT:**
public void Die() //death is called by a KillingObject event
{
m_bShootingAllowed = false; //to avoid spamming calls to this function
KillingObject.OnKill -= Die;
Instantiate (DieEffect, m_oTransform.position + DieEffectPosition, m_oTransform.rotation);
Debug.Log("Player is dead");
m_oTimer.Start(deathAnimationLength + mk_fTimeToRespawn, Respawn, false, deathAnimationLength, HidePlayerModel);
}
private void HidePlayerModel()
{
Debug.Log("hiding player model");
Renderer[] rs = GetComponentsInChildren();
foreach (Renderer r in rs)
r.enabled = false;
}
private void RestorePlayerModel()
{
Debug.Log("restoring player model");
Renderer[] rs = GetComponentsInChildren();
foreach (Renderer r in rs)
r.enabled = true;
}
private void Respawn()
{
Debug.Log("Player respawned");
Debug.Log (GameModule.GetInstance().GetCheckpointManager().GetRespawnPosition());
m_oTransform.position = GameModule.GetInstance().GetCheckpointManager().GetRespawnPosition ();
RestorePlayerModel();
OnRespawn (); //this is a delegate
KillingObject.OnKill += Die; //can die again
AllowShooting();
}
**PLAYER ANIMATION SCRIPT:**
void OnDie()
{
KillingObject.OnKill -= OnDie; //to avoid spamming calls to this function
_animator.Play("Death");
source.clip = deathSounds[Random.Range(0, deathSounds.Length)];
source.volume = .2f;
source.Play();
}
void OnRespawn()
{
KillingObject.OnKill += OnDie;
_animator.Play("Idle");
source.volume = 1f;
}
As you can see the player isn't destroyed on death, the model is disabled and enabled after a while (set by the Timer script).
The scene is loaded with a simple LoadScene();.
Thanks in advance for any help :(
