Question

我正在制作一个游戏项目，很有趣，我遇到一个为我的对话系统工作的单身人士的问题，当我用对话框系统加载场景时工作正常，但是如果我改变场景然后返回[Singleton]实例“ ConversationManager”已被破坏。返回null。

##
# configuration file for syslogd and aslmanager
##

? [= Sender firefox] ignore

# redirect com.apple.message.domain to /var/log/DiagnosticMessages
? [T com.apple.message.domain] store_dir /var/log/DiagnosticMessages exclude_asldb

# authpriv messages are root/admin readable
? [= Facility authpriv] access 0 80

# remoteauth critical, alert, and emergency messages are root/admin readable
? [= Facility remoteauth] [<= Level critical] access 0 80

# broadcast emergency messages
? [= Level emergency] broadcast

# save kernel [PID 0] and launchd [PID 1] messages
? [<= PID 1] store

# save everything from emergency to notice
? [<= Level notice] store

# save lpr info level and above
? [<= Level info] [= Facility lpr] store

# save all mail, ftp, local0, and local1 messages
? [= Facility mail] store
? [= Facility ftp] store
? [= Facility local0] store
? [= Facility local1] store

您需要确保不要破坏重物。您的逻辑有缺陷。向后看，下面不会在场景负载下破坏。如果要替换游戏对象，请确保它具有相同的值。

 void Awake()
    {
        //Check if instance already exists
        if (instance == null)

            //if not, set instance to this
            instance = this;

        //If instance already exists and it's not this:
        else if (instance != this)

            //Then destroy this. This enforces our singleton pattern, meaning there can only ever be one instance of a GameManager.
            Destroy(gameObject);    

        //Sets this to not be destroyed when reloading scene
        DontDestroyOnLoad(gameObject);
}

几乎没有什么老问题，但是最近在使用完全相同的Singleton脚本时遇到了同样的问题。

您不能在广告素材上使用[ExecuteInEditMode]属性实现该Singleton模式的类。

因此，请在您的类上删除该属性，然后将“编辑器”逻辑移至另一个非单一类。

单例实例“ ConversationManager”已被破坏。返回null
