常州手游开发培训-U3D监听Hierachy视图变化
对于初学者来说，不知道监听Hierarchy视图中创建或删除变化的事件也是可以理解的，为此下面给大家介绍下Unity中监听Hierachy视图的两种方法。
一、是EditorWindow.OnHierarchyChang这种要创建一个窗口，而且这个窗口关闭了就失效了，不管那么多来看常州网站开发培训实现代码：
using UnityEngine;
using System.Collections;
using UnityEditor;
public class HierachyChange : EditorWindow ｛
[MenuItem("Tools/HierachyChangeWindow")]
static void AddWindow()
｛
Rect wr = new Rect(0, 0, 500, 500);
HierachyChange window = (HierachyChange)EditorWindow.GetWindowWithRect(typeof(HierachyChange), wr, true, "widow name");
window.Show();
｝
void OnHierarchyChange()
｛
Debug.Log("当Hierarchy视图中的任何对象发生改变时调用一次,改变后保存当前场景还会调用一次");
｝
｝
该脚本要放在Editor文件夹下。
二、是雨松MOMO的一篇文章http://www.xuanyusong.com/archives/3053 中看到的。将他的代码贴出来，大家可以看看：
下面是常州企业培训子类他实现了上面的虚函数。
//这个是基类
using System;
using System.Collections;
using System.Reflection;
using UnityEditor;
using UnityEngine;
[InitializeOnLoad]
public class EditorMonoBehaviour
｛
static EditorMonoBehaviour()
｛
var type = Types.GetType("UnityEditor.EditorAssemblies", "UnityEditor.dll");
var method = type.GetMethod("SubclassesOf", BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Instance, null, new Type[] ｛ typeof(Type) ｝, null);
var e = method.Invoke(null, new object[] ｛ typeof(EditorMonoBehaviour) ｝) as IEnumerable;
foreach (Type editorMonoBehaviourClass in e)
｛
method = editorMonoBehaviourClass.BaseType.GetMethod("OnEditorMonoBehaviour", BindingFlags.NonPublic | BindingFlags.Instance);
if (method != null)
｛
method.Invoke(System.Activator.CreateInstance(editorMonoBehaviourClass), new object[0]);
｝
｝
｝
private void OnEditorMonoBehaviour()
｛
EditorApplication.update += Update;
EditorApplication.hierarchyWindowChanged += OnHierarchyWindowChanged;
EditorApplication.hierarchyWindowItemOnGUI += HierarchyWindowItemOnGUI;
EditorApplication.projectWindowChanged += OnProjectWindowChanged;
EditorApplication.projectWindowItemOnGUI += ProjectWindowItemOnGUI;
EditorApplication.modifierKeysChanged += OnModifierKeysChanged;
// globalEventHandler
EditorApplication.CallbackFunction function = () => OnGlobalEventHandler(Event.current);
FieldInfo info = typeof(EditorApplication).GetField("globalEventHandler", BindingFlags.Static | BindingFlags.Instance | BindingFlags.NonPublic);
EditorApplication.CallbackFunction functions = (EditorApplication.CallbackFunction)info.GetValue(null);
functions += function;
info.SetValue(null, (object)functions);
EditorApplication.searchChanged += OnSearchChanged;
EditorApplication.playmodeStateChanged += () => ｛
if (EditorApplication.isPaused)
｛
OnPlaymodeStateChanged(PlayModeState.Paused);
｝
if (EditorApplication.isPlaying)
｛
OnPlaymodeStateChanged(PlayModeState.Playing);
｝
if (EditorApplication.isPlayingOrWillChangePlaymode)
｛
OnPlaymodeStateChanged(PlayModeState.PlayingOrWillChangePlaymode);
｝
｝;
｝
public virtual void Update()
｛
｝
public virtual void OnHierarchyWindowChanged()
｛
｝
public virtual void HierarchyWindowItemOnGUI(int instanceID, Rect selectionRect)
｛
｝
public virtual void OnProjectWindowChanged()
｛
｝
public virtual void ProjectWindowItemOnGUI(string guid, Rect selectionRect)
｛
｝
public virtual void OnModifierKeysChanged()
｛
｝
public virtual void OnGlobalEventHandler(Event e)
｛
｝
public virtual void OnSearchChanged()
｛
｝
public virtual void OnPlaymodeStateChanged(PlayModeState playModeState)
｛
｝
public enum PlayModeState
｛
Playing,
Paused,
Stop,
PlayingOrWillChangePlaymode
｝
｝
下面是常州企业培训子类他实现了上面的虚函数。
using UnityEditor;
using UnityEngine;
public class NewBehaviourScript : EditorMonoBehaviour
｛
public override void Update()
｛
//Debug.Log ("每一帧回调一次");
｝
public override void OnPlaymodeStateChanged(PlayModeState playModeState)
｛
//Debug.Log ("游戏运行模式发生改变， 点击 运行游戏 或者暂停游戏或者 帧运行游戏 按钮时触发: " + playModeState);
｝
public override void OnGlobalEventHandler(Event e)
｛
//Debug.Log ("全局事件回调: " + e);
｝
public override void HierarchyWindowItemOnGUI(int instanceID, Rect selectionRect)
｛
// Debug.Log (string.Format ("｛0｝ : ｛1｝ - ｛2｝", EditorUtility.InstanceIDToObject (instanceID), instanceID, selectionRect));
｝
public override void OnHierarchyWindowChanged()
｛
Debug.Log("层次视图发生变化");
｝
public override void OnModifierKeysChanged()
｛
// Debug.Log ("当触发键盘事件");
｝
public override void OnProjectWindowChanged()
｛
// Debug.Log ("当资源视图发生变化");
｝
public override void ProjectWindowItemOnGUI(string guid, Rect selectionRect)
｛
//根据常州软件技术培训GUID得到资源的准确路径
//Debug.Log (string.Format ("｛0｝ : ｛1｝ - ｛2｝", AssetDatabase.GUIDToAssetPath (guid), guid, selectionRect));
｝
｝
把这两个类放在Editor文件夹里就行了。
