Question

在Unity中制作自定义EditorWindow时，我有多种类型的变量（枚举，bool，整数，字符串等）以及一个InputField。当然，当您输入值时，重启Unity时会忘记它们。所以为了解决这个问题，我创建了一个额外的类来保存这些值。

这适用于所有类型（bool，整数，字符串，枚举等），但我不知道如何为诸如InputField之类的统一组件保存赋值。

下面是我创建的代码，所有代码都有效，但是当我重新启动Unity时，我需要找到一种方法让工具不要忘记在inputField中从Hierarchy分配的对象。 < / p>

public class Tool : EditorWindow
{
    public InputField inputField;
    private bool myBool = true;
    private string myString = "Hello World";

    public void OnGUI()
    {
        inputField = (InputField)EditorGUILayout.ObjectField("Input Field", inputField, typeof(InputField), true);
        GetRestApiMain.myBool = EditorGUILayout.Toggle("Bool", GetRestApiMain.myBool );
        GetRestApiMain.myString = EditorGUILayout.TextField("Hello World", GetRestApiMain.myString);
    }
}

public class ToolReferences
{
    /* public static InputField inputField ?
     * {
     *     I don't know what to do here to save the InputField set by the user
     *     All the below works, and want to have the same for InputField
     *     whereby the assignment is not forgotten on restart.
     * } */

    public static bool myBool 
    {
        get
        {
#if UNITY_EDITOR
            return EditorPrefs.GetBool("Bool", false);
#else
            return false;
#endif
        }

        set
        {
#if UNITY_EDITOR
            EditorPrefs.SetBool("Bool", value);
#endif
        }
    }

    public static string myString 
    {
        get
        {
#if UNITY_EDITOR
            return EditorPrefs.GetString("Hello World", "");
#else
        return false;
#endif
        }
        set
        {
#if UNITY_EDITOR
            EditorPrefs.SetString("Hello World", value);
#endif
        }
    }
}

Answer 1

解决方案是在主类的OnGUI();中获取对象的InstanceID。然后将ID存储在另一个类的静态int中，而不是static InputField中。以下是工作代码。（感谢@ milan-egon-votrubec提供的InstanceID指针）

在将int设置为0之前，这不会删除您的分配，但是您可以替换它，并且它将在重新启动后保存。我敢肯定有更好的解决方案，但是目前，在多种场景下测试后，在单个场景中没有错误，此方法仍然有效。如果更改场景，除非使用预制件，否则它将丢失其分配。

ToolReferences类...

 // class ToolReferences
 public static int inputFieldId
    {
        get
        {
 #if UNITY_EDITOR
            return EditorPrefs.GetInt("inputFieldId", 0);
 #else
            return false;
 #endif
        }

        set
        {
 #if UNITY_EDITOR
            EditorPrefs.SetInt("inputFieldId", value);
 #endif
        }
    }

然后在工具类中...

 public class Tool : EditorWindow
 {
      public InputField inputField;
      // ...
      public void OnGUI()
      {
           inputField = (InputField)EditorGUILayout.ObjectField("Input Field", inputField, typeof(InputField), true);
           // if inputField has nothing currently assigned
           if (inputField == null)
           {
                // make sure we have and int stored
                if (ToolReferences.inputFieldId != 0)
                {
                     inputField = (InputField)EditorUtility.InstanceIDToObject(ToolReferences.inputFieldId);
                }
                else // ... prompt the user to assign one
           }
           // if we have an InputField assigned, store ID to int
           else if (inputField != null) ToolReferences.inputFieldId = inputField.GetInstanceID();
           }
       } 
 // ...
 }

Answer 2

您可以通过传入InputField实例将InputField InstanceID保存到EditorPrefs，然后反向检索它：

public static InputField GetInputField
{
  get
  {
    return EditorUtility.InstanceIDToObject(EditorPrefs.GetInt("InputFieldId"));
  }
  set
  {
    EditorPrefs.GetInt("InputFieldId", value.GetInstanceID());
  }
}

自定义Unity EditorWindow会忘记选定的GameObjects / Components
