列出场景对象Lightmap属性

首先上效果图：

　　编辑器代码：

using UnityEngine;

using UnityEditor;

using System.Collections;

public class LightmapAnalysisEditor : EditorWindow

{

    private static EditorWindow window;

    [MenuItem("MyEditor/LightmapAnalysis &q")]

    private static void Execute()

    {

        if (window == null)

            window = (LightmapAnalysisEditor)GetWindow(typeof(LightmapAnalysisEditor));

        window.minSize = new Vector2(, );

        window.Show();

    }

    private void OnGUI()

    {

        if (GUILayout.Button("光照贴图比例精度", GUILayout.Height(50f)))

        {

            GameObject go = GameObject.Find("LightmapScaleInfo");

            if(go == null)

            {

                go = new GameObject("LightmapScaleInfo");

            }

            var comp = go.GetComponent<LightmapScaleAnalysis>();

            if(comp == null)

            {

                comp = go.AddComponent<LightmapScaleAnalysis>();

            }

            Selection.activeObject = go;

            EditorGUIUtility.PingObject(go);

        }

    }

}

　　脚本代码：

#if UNITY_EDITOR

using UnityEngine;

using UnityEditor;

using System.Linq;

using System.Collections;

using System.Collections.Generic;

[ExecuteInEditMode]

public class LightmapScaleAnalysis : MonoBehaviour

{

    public GameObject target = null;

    public Dictionary<GameObject, float> dic = new Dictionary<GameObject, float>();

    public void Parse()

    {

        dic.Clear();

        if (target == null)

        {

            dic.Clear();

            return;

        }

        Renderer[] lstRenderer = target.GetComponentsInChildren<Renderer>();

        foreach(var r in lstRenderer)

        {

            // 非LightmapStatic

            StaticEditorFlags flag = GameObjectUtility.GetStaticEditorFlags(r.gameObject);

            if ((flag & StaticEditorFlags.LightmapStatic) == )

                continue;

            SerializedObject so = new SerializedObject(r);

            if (dic.ContainsKey(r.gameObject) == false)

            {

                dic.Add(r.gameObject, so.FindProperty("m_ScaleInLightmap").floatValue);

            }

            // dic = dic.OrderBy(o => o.Value).ToDictionary(o => o.Key, o => o.Value);

            List<KeyValuePair<GameObject, float>> lst = new List<KeyValuePair<GameObject, float>>(dic);

            lst.Sort(delegate(KeyValuePair<GameObject, float> s1, KeyValuePair<GameObject, float> s2)

            {

                return s2.Value.CompareTo(s1.Value);

            });

            dic.Clear();

            foreach(var l in lst)

            {

                dic.Add(l.Key, l.Value);

            }

        }

    }

}

　　脚本检视窗口：

#if UNITY_EDITOR

using UnityEngine;

using UnityEditor;

using System.Collections;

[CustomEditor(typeof(LightmapScaleAnalysis))]

    }

    public override void OnInspectorGUI()

    {

        DrawDefaultInspector();

        var analysis = target as LightmapScaleAnalysis;

        GUILayout.BeginHorizontal();

        specialRange = EditorGUILayout.Slider(specialRange, 0f, 1f);

        specialColor = EditorGUILayout.ColorField(specialColor);

        GUILayout.EndHorizontal();

        GUILayout.BeginVertical();

        GUILayout.BeginHorizontal();

        if (GUILayout.Button("解析吧"))

        {

        }

        GUILayout.EndHorizontal();

        foreach (var pair in analysis.dic)

        {

            GUILayout.BeginHorizontal();

            GUI.color = pair.Value >= specialRange ? specialColor : Color.white;

            EditorGUILayout.ObjectField(pair.Key, typeof(GameObject));
