支持自定义类型的预设

使用ObjectFactory类脚本一段代码，允许您创建自己的组件、触发游戏事件、随时间修改组件属性以及以您喜欢的任何方式响应用户输入。更多信息
请参阅术语表创建新的游戏对象Unity 场景中的基本对象，可以表示角色、道具、风景、相机、航路点等。游戏对象的功能由附加到它的组件定义。更多信息
请参阅术语表、组件和默认情况下支持和继承预设的资源。这ObjectFactory类会自动将默认预设应用于这些项目。

要默认支持和启用自定义类的预设，它们必须继承自以下内容之一：

预设检查器一个 Unity 窗口，显示有关当前选定游戏对象、资产或项目设置的信息，允许您检查和编辑值。更多信息
请参阅术语表window 创建类的临时实例，以便用户可以修改其值。因此，请确保你的类不会影响或依赖其他对象，例如静态值、项目资产或场景场景包含游戏的环境和菜单。将每个唯一的场景文件视为一个独特的关卡。在每个场景中，你放置你的环境、障碍物和装饰品，基本上是将你的游戏设计和构建成碎片。更多信息

示例：自定义编辑器窗口中的预设设置

以下一系列示例演示了如何将预设设置添加到简单的EditorWindow.创建自定义时EditorWindow类，其设置可以保存到预设中：

使用ScriptableObject以存储设置的副本。（可选）添加CustomEditor属性。预设系统处理此对象。
始终使用这个临时的ScriptableObjectInspector 以在 UI 中显示预设设置。这允许您的用户在您的EditorWindow就像编辑保存的预设一样。
公开预设按钮并使用您自己的按钮PresetSelectorReceiver实现以保持您的EditorWindow在“选择预设”窗口中选择预设时的设置是最新的。

以下示例演示了ScriptableObject在自定义窗口中保留和显示设置：

using UnityEngine;

// Temporary ScriptableObject used by the Preset system

public class MyWindowSettings : ScriptableObject
{
    [SerializeField]
    string m_SomeSettings;
    
    public void Init(MyEditorWindow window)
    {
        m_SomeSettings = window.someSettings;
    }
    
    public void ApplySettings(MyEditorWindow window)
    {
        window.someSettings = m_SomeSettings;
        window.Repaint();
    }
}

以下示例使用PresetSelectorReceiver更新ScriptableObject在自定义窗口中使用：

using UnityEditor.Presets;

// PresetSelector receiver to update the EditorWindow with the selected values.

public class MySettingsReceiver : PresetSelectorReceiver
{
    Preset initialValues;
    MyWindowSettings currentSettings;
    MyEditorWindow currentWindow;
    
    public void Init(MyWindowSettings settings, MyEditorWindow window)
    {
        currentWindow = window;
        currentSettings = settings;
        initialValues = new Preset(currentSettings);
    }
    
    public override void OnSelectionChanged(Preset selection)
    {
        if (selection != null)
        {
            // Apply the selection to the temporary settings
            selection.ApplyTo(currentSettings);
        }
        else
        {
            // None have been selected. Apply the Initial values back to the temporary selection.
            initialValues.ApplyTo(currentSettings);
        }
        
        // Apply the new temporary settings to our manager instance
        currentSettings.ApplySettings(currentWindow);
    }
    
    public override void OnSelectionClosed(Preset selection)
    {
        // Call selection change one last time to make sure you have the last selection values.
        OnSelectionChanged(selection);
        // Destroy the receiver here, so you don't need to keep a reference to it.
        DestroyImmediate(this);
    }
}

以下示例创建了一个EditorWindow使用临时 ScriptableObject Inspector 及其预设按钮显示自定义设置：

using UnityEngine;
using UnityEditor;
using UnityEditor.Presets;

public class MyEditorWindow : EditorWindow

{
    // get the Preset icon and a style to display it
    private static class Styles
    {
        public static GUIContent presetIcon = EditorGUIUtility.IconContent("Preset.Context");
        public static GUIStyle iconButton = new GUIStyle("IconButton");

    }

    Editor m_SettingsEditor;
    MyWindowSettings m_SerializedSettings;
    
    public string someSettings
    {
        get { return EditorPrefs.GetString("MyEditorWindow_SomeSettings"); }
        set { EditorPrefs.SetString("MyEditorWindow_SomeSettings", value); }
    }
   
    // Method to open the window
    [MenuItem("Window/MyEditorWindow")]
    static void OpenWindow()
    {
        GetWindow<MyEditorWindow>();
    }

    void OnEnable()
    {
        // Create your settings now and its associated Inspector
        // that allows to create only one custom Inspector for the settings in the window and the Preset.
        m_SerializedSettings = ScriptableObject.CreateInstance<MyWindowSettings>();
        m_SerializedSettings.Init(this);
        m_SerializedSettings.hideFlags = HideFlags.DontSave;
        m_SettingsEditor = Editor.CreateEditor(m_SerializedSettings);
        m_SettingsEditor.hideFlags = HideFlags.DontSave;
    }

    void OnDisable()
    {
        Object.DestroyImmediate(m_SerializedSettings);
        Object.DestroyImmediate(m_SettingsEditor);
    }

    void OnGUI()
    {
        EditorGUILayout.BeginHorizontal();
        EditorGUILayout.LabelField("My custom settings", EditorStyles.boldLabel);
        GUILayout.FlexibleSpace();
        // create the Preset button at the end of the "MyManager Settings" line.
        var buttonPosition = EditorGUILayout.GetControlRect(false, EditorGUIUtility.singleLineHeight, Styles.iconButton);

        if (EditorGUI.DropdownButton(buttonPosition, Styles.presetIcon, FocusType.Passive, Styles.iconButton))
        {
            // Create a receiver instance. This destroys itself when the window appears, so you don't need to keep a reference to it.
            var presetReceiver = ScriptableObject.CreateInstance<MySettingsReceiver>();
            presetReceiver.Init(m_SerializedSettings, this);
            // Show the PresetSelector modal window. The presetReceiver updates your data.
            PresetSelector.ShowSelector(m_SerializedSettings, null, true, presetReceiver);
        }
        EditorGUILayout.EndHorizontal();
        
        // Draw the settings default Inspector and catch any change made to it.
        EditorGUI.BeginChangeCheck();
        m_SettingsEditor.OnInspectorGUI();

        if (EditorGUI.EndChangeCheck())
        {
            // Apply changes made in the settings editor to our instance.
            m_SerializedSettings.ApplySettings(this);
        }
    }
}
