Pourquoi mon singleton est-il nul?

Question

J'essaie personnalisé NetworkManager mais il continue à donner

NullReferenceException

... dans la commande NetworkManager.singleton.StartHost();

le problème est à la ligne NetWorkManager.Singleton.StartHost(); dans le auj StartGame(); toujours revenir

... et je ne sais pas pourquoi ça arrive

Voici le code.

using UnityEngine; 
using UnityEngine.Networking; 
using System.Collections; 
using UnityEngine.UI; 

public class NetManager : NetworkManager { 

    public Transform Bombeiro, Cnen, Policial, Suspeito,IaTeamPlayer; 
    public string ServidorIP, NomeUsuario; 
    private GameObject WayPoint; 
    public int GrupoAvatar; 
    public bool IniciarServidor; 
    public GameObject Lacamera,menu; 
    private Transform IA; 
    private MandaRad recptor; 
    private SobeRampa CodigoSubida; 
    public GameObject[] BombeiroSpawnPoints; 
    public GameObject[] PolicialSpawnPoints; 
    public GameObject[] SuspeitoSpawnPoints; 
    public GameObject[] CnenSpawnPoints; 
    private GameObject[] pedestres; 
    GameObject spawnPos; 
    void Awake() 
    { 
     BombeiroSpawnPoints = GameObject.FindGameObjectsWithTag("spawnBombeiroTeam"); 
     PolicialSpawnPoints = GameObject.FindGameObjectsWithTag("spawnPolicialTeam"); 
     SuspeitoSpawnPoints = GameObject.FindGameObjectsWithTag ("spawnSuspeitoTeam"); 
     CnenSpawnPoints = GameObject.FindGameObjectsWithTag ("spawnCnemTeam"); 
    } 

    public void ServerIni (bool iniciar) 
    { 
     IniciarServidor = iniciar; 
    } 

    public void PegaCampoIP(GameObject IP) 
    { 
     if (IP.GetComponent<InputField>().text == "") 
      ServidorIP = IP.GetComponent<InputField>().placeholder.GetComponent<Text>().text; 
     else 
      ServidorIP = IP.GetComponent<InputField>().text; 
    } 

    public void PegaCampoNome(GameObject Nome) 
    { 
     if (Nome.GetComponent<InputField>().text == "") 
      NomeUsuario = Nome.GetComponent<InputField>().placeholder.GetComponent<Text>().text; 
     else 
      NomeUsuario = Nome.GetComponent<InputField>().text; 
    } 

    public void EscolherAvatar (int grupo) 
    { 

     if (GrupoAvatar == 0) 
     { 
      spawnPos = BombeiroSpawnPoints[Random.Range(0, BombeiroSpawnPoints.Length)]; 
      base.playerPrefab = Bombeiro.gameObject; 
      base.spawnPrefabs.RemoveAt(0); 
      base.spawnPrefabs.Add(spawnPos); 
     } 
     else if (GrupoAvatar == 1) 
     { 
      spawnPos = CnenSpawnPoints[Random.Range(0, CnenSpawnPoints.Length)]; 
      base.playerPrefab = Cnen.gameObject; 
      base.spawnPrefabs.RemoveAt(0); 
      base.spawnPrefabs.Add(spawnPos); 
     } 
     else if (GrupoAvatar == 2) 
     { 
      spawnPos = PolicialSpawnPoints[Random.Range(0, PolicialSpawnPoints.Length)]; 
      base.playerPrefab = Policial.gameObject; 
      base.spawnPrefabs.RemoveAt(0); 
      base.spawnPrefabs.Add(spawnPos); 
     } 
     else if (GrupoAvatar == 3) 
     { 
      spawnPos = SuspeitoSpawnPoints[Random.Range(0, SuspeitoSpawnPoints.Length)]; 
      base.playerPrefab = Suspeito.gameObject; 
      base.spawnPrefabs.RemoveAt(0); 
      base.spawnPrefabs.Add(spawnPos); 
     } 

     if (IniciarServidor) 
      StartGame(); 
     else 
      JoinGame(); 
    } 

    public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId) 
    { 
     GameObject player = (GameObject)Instantiate (base.playerPrefab, spawnPos.transform.position, spawnPos.transform.rotation); 
     NetworkServer.AddPlayerForConnection (conn, player, playerControllerId); 
    } 

    public void StartGame() 
    { 
     NetworkManager.singleton.StartHost(); 
    } 

    public void JoinGame() 
    { 
     NetworkManager.singleton.networkAddress = ServidorIP; 
     NetworkManager.singleton.StartClient(); 
    } 
} 

Il a été fait à l'unité 5 Alors, comment je peux résoudre ce ??

Answer 1

Je pense que vous n'avez peut-être pas initialisé NetworkManager.singleton? L'avez-vous déjà utilisé comme instance de NetworkManager?

Answer 2

Cela est dû au fait que vous remplacez la fonction Réveil. Il n'est pas marqué, mais j'ai trouvé que l'implémentation du Awake bloque l'assignation Unity standard du singleton.

, retirez votre Awake ou ne singleton = vous-même
