C# 无法在Unity中实例化行为

我是Unity 3D的新手（非常新，事实上不到8小时）

事实证明，我对统一的陌生感给我带来了一个相当奇怪的问题。考虑以下两个行为：

行为

CamCaptureDialogBehavior

：

using UnityEngine;
using System.Collections;

public class CamCaptureDialogBehavior : MonoBehaviour
{
        // 200x300 px window will apear in the center of the screen.
        private Rect windowRect = new Rect ((Screen.width - 200) / 2, (Screen.height - 300) / 2, 200, 300);
        // Only show it if needed.
        private bool show = false;

        public CamCaptureDialogBehavior ()
        {
        }
        // Use this for initialization
        void Start ()
        {

        }

        void OnGUI ()
        {
                if (show)
                        windowRect = GUI.Window (0, windowRect, DialogWindow, "Game Over");
        }

        void DialogWindow (int windowID)
        {
                float y = 20;
                GUI.Label (new Rect (5, y, windowRect.width, 20), "Title goes here");

                if (GUI.Button (new Rect (5, y, windowRect.width - 10, 20), "Ok")) {
                        Application.LoadLevel (0);
                        show = false;
                }
        }

        // To open the dialogue from outside of the script.
        public void Open ()
        {
                show = true;
        }
        // Update is called once per frame
        void Update ()
        {

        }
}

using UnityEngine;
using UnityEditor;
using System.Collections;

public class PictureButtonBehavior : MonoBehaviour
{
        private bool displayedGUI = false;
        private bool ShowThisGUI = false;

        void Start ()
        {
        }

        void Update ()
        {
                if (displayedGUI == true) {
                        Debug.Log (string.Format ("displayedGUI = {0}\r\n", displayedGUI));
                        displayedGUI = false;
                        ShowThisGUI = false;
                }
        }

        void OnGUI ()
        {
                if (ShowThisGUI) {
                        Debug.Log (string.Format ("ShowThisGUI = {0}\r\n", ShowThisGUI));
                        displayedGUI = true;
                        ShowThisGUI = false;
                        CamCaptureDialogBehavior ccdb = new CamCaptureDialogBehavior ();
                        if (ccdb != null) {
                                ccdb.enabled = true;
                                ccdb.Open ();
                        }
                }
        }

        public void OnClick ()
        {
                ShowThisGUI = true;
        }
}

行为：

PictureButtonBehavior

：

using UnityEngine;
using System.Collections;

public class CamCaptureDialogBehavior : MonoBehaviour
{
        // 200x300 px window will apear in the center of the screen.
        private Rect windowRect = new Rect ((Screen.width - 200) / 2, (Screen.height - 300) / 2, 200, 300);
        // Only show it if needed.
        private bool show = false;

        public CamCaptureDialogBehavior ()
        {
        }
        // Use this for initialization
        void Start ()
        {

        }

        void OnGUI ()
        {
                if (show)
                        windowRect = GUI.Window (0, windowRect, DialogWindow, "Game Over");
        }

        void DialogWindow (int windowID)
        {
                float y = 20;
                GUI.Label (new Rect (5, y, windowRect.width, 20), "Title goes here");

                if (GUI.Button (new Rect (5, y, windowRect.width - 10, 20), "Ok")) {
                        Application.LoadLevel (0);
                        show = false;
                }
        }

        // To open the dialogue from outside of the script.
        public void Open ()
        {
                show = true;
        }
        // Update is called once per frame
        void Update ()
        {

        }
}

using UnityEngine;
using UnityEditor;
using System.Collections;

public class PictureButtonBehavior : MonoBehaviour
{
        private bool displayedGUI = false;
        private bool ShowThisGUI = false;

        void Start ()
        {
        }

        void Update ()
        {
                if (displayedGUI == true) {
                        Debug.Log (string.Format ("displayedGUI = {0}\r\n", displayedGUI));
                        displayedGUI = false;
                        ShowThisGUI = false;
                }
        }

        void OnGUI ()
        {
                if (ShowThisGUI) {
                        Debug.Log (string.Format ("ShowThisGUI = {0}\r\n", ShowThisGUI));
                        displayedGUI = true;
                        ShowThisGUI = false;
                        CamCaptureDialogBehavior ccdb = new CamCaptureDialogBehavior ();
                        if (ccdb != null) {
                                ccdb.enabled = true;
                                ccdb.Open ();
                        }
                }
        }

        public void OnClick ()
        {
                ShowThisGUI = true;
        }
}

在

CamCaptureDialogBehavior ccdb=new CamCaptureDialogBehavior（），
ccdb
始终为
null

在Unity/Mono中有没有一种实例化类的方法

或者，我如何在
PictureButtonBehavior
中实例化
CamCaptureDialogBehavior
，并能够显示由
CamCaptureDialogBehavior
表示的对话框

您可以实例化附加了脚本的预置

GameObject g = Instantiate(prefab) as GameObject;

或者你可以将它们添加到已经存在的游戏对象中

gameObject.AddComponent<ScriptName>();

gameObject.AddComponent（）；


接下来你会问什么是预制件。这是一件非常简单的事情，但在统一中非常强大。关于如何制作一个

您可以通过选择资源>创建预置来创建预置，然后
将对象从场景拖动到“空”预设资源上
出现。只需将预制资源从项目视图拖动到
然后，“场景视图”将创建预置的实例

如果它源于单一行为，不要使用新的。使用initiate->我尝试使用initiate，但要使用initiate，首先需要有一个initiated值。它仍然返回空值。您可以使用资源。如果没有要克隆的实例，请加载：）我无法使其正常工作（我太新了：P），但感谢您为我指明了正确的资源。我已经解决了这个问题，但是动态创建寡妇。
