前言

我们都知道在Unity的工程中,ProjectIt contains all the resources of our project.When we click the right mouse button, a menu will pop up：

If we want to expand these content, how should we expand?？
Here I make some summaries.

Project视图

We create a new script to controlProject的拓展：


In fact, we carefully found thisProject's view is actually the same as our topAssetsThe pop-up content of the menu bar is consistent,所以我们对ProjectExpansion of content isAssetsExpand the menu bar.结合前面第一节We know that we only need to change the root directory..

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
public class TestProject : MonoBehaviour
{
    
    [MenuItem("Assets/Test1")]
    static void Test1() 
    {
    
    }
}

Here we will not introduce more details.,可以看第一节
If we need to click on the custombuttonWhen can be achieved：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
public class TestProject : MonoBehaviour
{
    
    [MenuItem("Assets/Test1")]
    static void Test1() 
    {
    
        //EditorApplication.projectWindowItemOnGUIWhen is open the option is invoked
        EditorApplication.projectWindowItemOnGUI += (guid, rect) =>
        {
    
            ///Capture parameter list
            ///1.Unique identifier for the file 2.
            ///用GUI绘制一个按钮
            GUI.Button(new Rect(100, 100, 100, 100),"Test1");
        };
    }
    //The following is the time to load is called,Both are based on demand
    [InitializeOnLoadMethod]
    static void InitializeOnload() 
    {
    
        EditorApplication.projectWindowItemOnGUI += (guid, rect) =>
        {
    
            ///Capture parameter list
            ///1.Unique identifier for the file 2.
            ///用GUI绘制一个按钮
            GUI.Button(new Rect(100, 100, 100, 100), "Test1");
        };
    }
}

效果如下：

If we want a delete button to appear after the script is clicked,Then delete the corresponding prefab:

So what should such a function do?？具体如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
public class TestProject : MonoBehaviour
{
    
    [MenuItem("Assets/Test1")]
    static void Test1()
    {
    
        
    }
    //The following is the time to load is called,Both are based on demand
    [InitializeOnLoadMethod]
    static void InitializeOnload()
    {
    
        EditorApplication.projectWindowItemOnGUI += (guid, rect) =>
        {
    

            if(Selection.activeObject != null) 
            {
    
                //Get the currently selected objectguid
                string m_guid = AssetDatabase.AssetPathToGUID(AssetDatabase.GetAssetPath(Selection.activeObject));
                if (m_guid == guid) 
                {
    
                    rect.x = rect.width - 100;
                    rect.width = 100;
                    if (GUI.Button(rect, "Test1")) 
                    {
    
                        //删除
                        AssetDatabase.DeleteAsset(AssetDatabase.GetAssetPath(Selection.activeObject));
                        Debug.Log("删除当前对象" + AssetDatabase.GetAssetPath(Selection.activeObject));
                    }

                }
            }
            /Capture parameter list
            /1.Unique identifier for the file 2.
            /用GUI绘制一个按钮
            //GUI.Button(new Rect(100, 100, 100, 100), "Test1");
        };
    }
}

Project事件监听

新建一个脚本TestProjectEventto control event listeners

Here we no longer inheritUnity中的MonoBehaviour类,instead inheritUnityEditor.AssetModificationProcessora class like this

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TestProjectEvent : UnityEditor.AssetModificationProcessor
{
    
}

1. 监听文件创建

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TestProjectEvent : UnityEditor.AssetModificationProcessor
{
    
    //Called before the resource is created
    public static void OnWillCreateAsset(string path) 
    {
    
        //pathIs a path we are going to create the resources
        Debug.LogFormat("创建资源{0}",path);
    }
}

Let's drag a picture to try the effect：

2. Monitoring file save

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TestProjectEvent : UnityEditor.AssetModificationProcessor
{
    
   [InitializeOnLoadMethod]
   static void InitOnLoad()
   {
    
       //resource change call
       EditorApplication.projectChanged += () =>
       {
    
           Debug.Log("资源发生了改变");
       };
   }
}
