Unity編輯器擴充套件

1 在工程目錄下新建 Editor 資料夾

Editor資料夾內的資源都不會被打包出去（包括PC 移動端等 只會在unity的編輯器模式執行）

  //正常的新增選單欄

    [MenuItem("Tools/test")]

    static void Test()

    {

        Debug.Log("test");

}

如果要新增 選單欄的分割線

   [MenuItem("Tools/test1", false, 1)]

    static void Test1()

    {

        Debug.Log("test1");

    }

    [MenuItem("Tools/test2", false, 12)]

    static void Test2()

    {

        Debug.Log("test2");

    }

    [MenuItem("Tools/test3",false ,0),]

    static void Test3()

    {

        Debug.Log("test3");

}
 

第三個引數 priority  是1-1000  相當於層級 越小越靠上

相差大於11 就會出現 一條橫槓

要想在Gameobject 選單欄 新增子選單

 [MenuItem("GameObject/ My test",false,10)]

    static void Test()

    {

        Debug.Log("test2");

    }

2 指令碼的編輯器擴充套件

在Editor新建PlayerEditor指令碼

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

public class PlayerEditor   {

    //CONTEXT 固定寫法
    //PlayerHealth 指令碼名（元件名）
    //InitHealthAndSpeed 按鈕名稱
    [MenuItem("CONTEXT/PlayerHealth/InitHealthAndSpeed")]

  
    static void InitHealthAndSpeed()
    {
        Debug.Log("Init");
    }
	 
}
 

MenuCommand 用法

   //CONTEXT 固定寫法
    //PlayerHealth 指令碼名（元件）
    //InitHealthAndSpeed 按鈕名稱
    [MenuItem("CONTEXT/PlayerHealth/InitHealthAndSpeed")]

  
    static void InitHealthAndSpeed(MenuCommand menu) //MenuCommand 是當前正在操作的元件
    {
        Debug.Log(menu.context.name);
        Debug.Log("Init");
    }
	 
 

修改PlayerHealth中的引數

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

public class PlayerEditor   {

    //CONTEXT 固定寫法
    //PlayerHealth 指令碼名（元件）
    //InitHealthAndSpeed 按鈕名稱
    [MenuItem("CONTEXT/PlayerHealth/InitHealthAndSpeed")]

  
    static void InitHealthAndSpeed(MenuCommand menu) //MenuCommand 是當前正在操作的元件
    {
        Debug.Log(menu.context.name); 
        Debug.Log("Init");
        PlayerHealth ph = (PlayerHealth)menu.context;
        ph.name = "haha";
    }
	 
}

cube的名字就變成了haha

3 清空rigidbody元件

編寫程式碼

 [MenuItem("CONTEXT/Rigidbody/Clear")]
    static void ClearMassAdnGravity(MenuCommand cmd)
    {
        Rigidbody rigidbody = (Rigidbody)cmd.context;
        rigidbody.mass = 0;
        rigidbody.useGravity = false;
    }

4 刪除 所選擇的 gameobject【】

  [MenuItem("Tools/test2", false, 12)]
    static void Test2()
    {
        Debug.Log(Selection.activeObject.name);//是我們選擇的第一個遊戲物體
    }

Selection 是一個靜態的選擇類

    [MenuItem("Tools/test2", false, 12)]
    static void Test2()
    {
       // Debug.Log(Selection.activeObject.name);
        foreach (GameObject item in Selection.gameObjects)
        {
            Debug.Log(  item.name);
            Undo.DestroyObjectImmediate(item); //（能用 Ctrl+z 來撤銷}）））
            // GameObject.DestroyImmediate(item);  
        }

    }

5 新增快捷鍵

    //%=ctrl # =shift &=alt
    [MenuItem("Tools/test2  %q", false, 12)]
    static void Test2()
    {
       // Debug.Log(Selection.activeObject.name);
        foreach (GameObject item in Selection.gameObjects)
        {
            Debug.Log(  item.name);
            Undo.DestroyObjectImmediate(item);
            // GameObject.DestroyImmediate(item);  
        }

    }
    //%=ctrl # =shift &=alt
    [MenuItem("Tools/test3 _t" ,false ,0),]  //快捷鍵為T
    static void Test3()
    {
        Debug.Log("test3");
    }

只有選擇的有物體的時候才能被點選

    [MenuItem("GameObject/ My delete", true, 11)]
    static bool MyDeleteValidate()
    {
        if (Selection.gameObjects.Length>0)
        {
            return true;
        }
        else
        {
            return false;
        }
    }

    [MenuItem("GameObject/ My delete", false, 11)]
    static void Test3()
    {
        Debug.Log("test3");
    }

另一種方法

屬性也有一種

6 如何建立對話方塊

在Editor下建立EnemyChange 指令碼 整合至ScriptabkeWizard

using UnityEditor;

public class EnemyChange : ScriptableWizard {

    public int hp = 10;

	 
}

在Tools下新建方法

   [MenuItem("Tools/CreateWuzard")]
    static void CreateWuzard()
    {
        ScriptableWizard.DisplayWizard<EnemyChange>("統一修改敵人");
    }

可以吧兩個方法整合到一個方法裡

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

public class EnemyChange : ScriptableWizard {

    public int hp = 10;

    [MenuItem("Tools/CreateWuzard")]
    static void CreateWuzard()
    {
        ScriptableWizard.DisplayWizard<EnemyChange>("統一修改敵人","ChangeValue" );
    }
    //檢測 Create按鈕的點選
    public void OnWizardCreate()
    {

     GameObject[] games =     Selection.gameObjects;
        foreach (GameObject item in games)
        {
            item.GetComponent<PlayerHealth>().hp += hp;
        }


        Debug.Log("click");
    }

}

選擇多個一起修改變數

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

public class EnemyChange : ScriptableWizard {

    public int hp = 10;

    [MenuItem("Tools/CreateWuzard")]
    static void CreateWuzard()
    {
        ScriptableWizard.DisplayWizard<EnemyChange>("統一修改敵人","ChangeValue" ,"Other Button");
    }
    //檢測 Create按鈕的點選
    public void OnWizardCreate()
    {

     GameObject[] games =     Selection.gameObjects;
        foreach (GameObject item in games)
        {
            PlayerHealth playerHealth = item.GetComponent<PlayerHealth>();
            Undo.RecordObject(playerHealth, "change"); //更改之前摁下快門 可以撤銷 ctrl+z
            playerHealth. hp += hp; 
        } 
 ShowNotification(new GUIContent(games.Length+ "個遊戲物體的值被修改了"));
        Debug.Log("click");
    }
void OnWizardOtherButton()
{
//這個按鈕方法不會關閉 小視窗
}
void OnWizardUpdate()//當對話方塊彈出 和修改了欄位的值的時候呼叫
{
    errorString ="";
    helpString="";
    if(Selection.gameObjects.lenth>0){
    helpString+"您當前選擇了"+Selection.gameObjects.Lenght+"個敵人";
}
    else{
        errorString ="請至少選擇一個敵人"; //errorString  資訊報錯

         Debug.Log("update");
    }

void OnSelectionChange(){
OnWizardUpdate();
}


}
