Unity Inspector 给组件自动关联引用

通过声明的变量名称,主动关联引用.  
使用这个关联引用两种方式

1.  给你组件继承 MonoAutoQuote 点击组件inspector 按钮执行
2.  给你组件类添加\[AAutoQuote\] 特性 通过Plateface/SetSelectGameRef 执行

\[AAutoQuote\]public class MonoAutoQuote : MonoBehaviour ,IAutoQuote\{\}  
public interface IAutoQuote \{ \}  
public class AAutoQuote : Attribute \{\}

using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEditor;using System.Reflection;

//\[CanEditMultipleObjects\]  
\[CustomEditor(typeof(MonoAutoQuote), true)\]public class AutoQuoteEditor : Editor  
\{  
public override void OnInspectorGUI()  
\{  
base.OnInspectorGUI();

if (GUILayout.Button("关联子节点引用"))  
\{  
Component c = target as Component;  
if (c != null)  
AutioQuoteMenu.SetRef(c, c.gameObject);  
\}

\}  
\}  
public class AutioQuoteMenu  
\{  
\[MenuItem("Plateface/SetSelectGameRef %&A")\]  
public static void SetRef()  
\{  
GameObject o = Selection.activeGameObject;  
if (o != null)  
\{  
Component\[\] cAry = o.GetComponents();  
foreach (var c in cAry)  
\{  
System.Type componentType = c.GetType();  
if ((typeof(MonoBehaviour).IsAssignableFrom(componentType)) || IsHasAttribute(componentType))  
\{  
SetRef(c, o);  
\}  
\}  
\}  
\}

public static void SetRef(Component c, GameObject o)  
\{  
System.Type t = c.GetType();  
var infoList = t.GetFields(BindingFlags.Public | BindingFlags.Instance);  
System.Text.StringBuilder sb = new System.Text.StringBuilder();  
string name = string.Empty;  
foreach (var item in infoList)  
\{  
var fieldType = item.FieldType;

if ((typeof(MonoBehaviour).IsAssignableFrom(fieldType)))  
\{  
if (item.Name.StartsWith("m"))  
\{  
name = item.Name.Substring(1);  
Transform tr = o.transform.Find(name);  
if (tr == null)  
\{  
Debug.LogError(name + "引用没找到");  
continue;  
\}

Component com = tr.GetComponent(fieldType);  
item.SetValue(c, com);  
\}  
\}  
\}  
\}

public static bool IsHasAttribute(System.Type type)  
\{  
System.Object\[\] oList = type.GetCustomAttributes(typeof(AAutoQuote), false);  
foreach (var item in oList)  
\{  
if ((item as AAutoQuote) != null)  
return true;  
\}

return false;  
\}  
\}
