Unity编辑器

这篇文章主要总结一下最近工作时写的一些编辑器，总结了三种常用的编辑器编写方式：

• Inspector Editor
• EditorWindow
• ScriptableWizard

Inspector Editor

利用CustomEditor特性挂接Script来实现Inspector界面显示

首先我们给出对应的Script代码，主要是为了提供Inspector面板的参数而用

public class SampleEditorScript : MonoBehaviour
{
    public int sliderNum = 0;
    public int intNum = 0;
    public float floatNum = 0f;
    public string str = "";
    public Vector2 pos = Vector2.zero;
}

之后写对应的Editor文件

// 脚本为前面编写的数据脚本
[CustomEditor(typeof(SampleEditorScript))]
// [CanEditMultipleObjects] 多对象编辑
public class SampleEditor : Editor
{
    SerializedProperty sliderNum;
    SerializedProperty intNum;
    SerializedProperty floatNum;
    SerializedProperty str;
    SerializedProperty pos;

    void OnEnable()
    {
        // 将值传给对应的SerializedProperty
        sliderNum = serializedObject.FindProperty("sliderNum");
        intNum = serializedObject.FindProperty("intNum");
        floatNum = serializedObject.FindProperty("floatNum");
        str = serializedObject.FindProperty("str");
        pos = serializedObject.FindProperty("pos");
    }

    /// <summary>
    /// 绘制Inspector窗口
    /// </summary>
    public override void OnInspectorGUI()
    {
        // 每次绘制insperctor面板的时候都应该更新一下serializedObjectd的数据
        serializedObject.Update();

        // 除PropertyField函数外，正常函数也封装了传入SerializedProperty的用法
        EditorGUILayout.IntSlider(sliderNum, 0, 100, new GUIContent("Slider"));
        ProgressBar(sliderNum.intValue / 100.0f, "Slider Num");

        // PropertyField好处为自动识别类型
        EditorGUILayout.PropertyField(intNum, new GUIContent("Int Num"));
        EditorGUILayout.PropertyField(floatNum, new GUIContent("Float Num"));
        EditorGUILayout.PropertyField(str, new GUIContent("string"));
        EditorGUILayout.PropertyField(pos, new GUIContent("Vector2"));

        // 将数据更改应用于serializedObject
        serializedObject.ApplyModifiedProperties();
    }

    /// <summary>
    /// 绘制Scene窗口
    /// </summary>
    void OnSceneGUI()
    {
        // 绘制的线为红色
        Handles.color = Color.red;
        // 在点(0,0,0)到(1,1,1)画一条红线
        Handles.DrawLine(Vector3.zero, Vector3.one);
    }

    /// <summary>
    /// 自定义进度条
    /// </summary>
    /// <param name="value">进度条值</param>
    /// <param name="label">进度条名字</param>
    void ProgressBar(float value, string label)
    {
        // 为文本框绘制一个进度条
        Rect rect = GUILayoutUtility.GetRect(18, 18, "TextField");
        EditorGUI.ProgressBar(rect, value, label);
        EditorGUILayout.Space();
    }
}

EditorWindow

创建一个编辑器视窗，视窗可以内嵌到Unity编辑器中

public class SampleEditorWindow : EditorWindow
{
    private int intNum = 0;
    private float floatNum = 0f;
    private string str = "";
    private Vector2 SVPos;

    /// <summary>
    /// 菜单栏响应函数
    /// </summary>
    [MenuItem("EditorTools/SampleEditorWindow")]
    static void Init()
    {
        // 初始化窗口并显示
        SampleEditorWindow window = (SampleEditorWindow)GetWindow(typeof(SampleEditorWindow));
        window.Show();
    }

    /// <summary>
    /// 界面绘制函数
    /// </summary>
	  void OnGUI()
	  {
        // 绘制可用EditorGUILayout、GUILayout所提供的函数等

        // 竖直排版
        EditorGUILayout.BeginHorizontal();
        // 滑动组件
        SVPos = EditorGUILayout.BeginScrollView(SVPos);
        // int输入框
        intNum = EditorGUILayout.IntField("Int Num", intNum);
        // float输入框
        floatNum = EditorGUILayout.FloatField("Float Num", floatNum);
        // string输入框
        str = EditorGUILayout.TextField("string", str);
        // 等等...
        EditorGUILayout.EndScrollView();
        EditorGUILayout.EndHorizontal();
    }
}

ScriptableWizard

创建一个编辑器导航视窗

public class SampleScriptableWizard : ScriptableWizard
{
    public int intNum = 0;
    public float floatNum = 0f;
    public string str = "";

    [MenuItem("EditorTools/SampleScriptableWizard")]
    static void Init()
    {
        ScriptableWizard.DisplayWizard<SampleScriptableWizard>("Wizard界面", "Wizard按钮", "Wizard另一个按钮");
    }

    /// <summary>
    /// 界面的刷新
    /// </summary>
    void OnWizardUpdate()
    {
        helpString = "这是一条提示语句";
    }

	  /// <summary>
	  /// 按钮执行功能
	  /// </summary>
    void OnWizardCreate()
    {
        Debug.Log("点击按钮");
    }

    void OnWizardOtherButton()
    {
        Debug.Log("点击另一个按钮");
    }
}
