Unity 实现删除missing脚本组件

通过Resources.FindObjectsOfTypeAll查找所有GameObject，然后通过.hideFlags == HideFlags.None判断是否为存在于Hierarchy面板。（此为编辑器脚本）

详细代码：

/*******************************************************************************
* 版本声明：v1.0.0
* 类 名 称：DeleteMissingScripts
* 创建日期：8/10/2019 5:04:13 PM
* 作者名称：末零
* 功能描述：删除所有Miss的脚本
******************************************************************************/ 
using UnityEngine;
using UnityEditor; 
public class DeleteMissingScripts
{
    [MenuItem("MyTools/Delete Missing Scripts")]
    static void CleanupMissingScript()
    {
        GameObject[] pAllObjects = (GameObject[])Resources.FindObjectsOfTypeAll(typeof(GameObject));
 
        int r;
        int j;
        for (int i = 0; i < pAllObjects.Length; i++)
        {
            if (pAllObjects[i].hideFlags == HideFlags.None)//HideFlags.None 获取Hierarchy面板所有Object
            {
                var components = pAllObjects[i].GetComponents<Component>();
                var serializedObject = new SerializedObject(pAllObjects[i]);
                var prop = serializedObject.FindProperty("m_Component");
                r = 0;
 
                for (j = 0; j < components.Length; j++)
                {
                    if (components[j] == null)
                    {
                        prop.DeleteArrayElementAtIndex(j - r);
                        r++;
                    }
                } 
                serializedObject.ApplyModifiedProperties();
            }
        }
    }
}

补充：Unity中一键删除所有已失效的脚本

如下所示：

//删除所有Miss的脚本 
using UnityEngine;
using UnityEditor; 
public class DeleteMissingScripts
{
    [MenuItem("MyTools/Delete Missing Scripts")]
    static void CleanupMissingScript()
    {
        GameObject[] pAllObjects = (GameObject[])Resources.FindObjectsOfTypeAll(typeof(GameObject));
 
        int r;
        int j;
        for (int i = 0; i < pAllObjects.Length; i++)
        {
            if (pAllObjects[i].hideFlags == HideFlags.None)//HideFlags.None 获取Hierarchy面板所有Object
            {
                var components = pAllObjects[i].GetComponents<Component>();
                var serializedObject = new SerializedObject(pAllObjects[i]);
                var prop = serializedObject.FindProperty("m_Component");
                r = 0;
 
                for (j = 0; j < components.Length; j++)
                {
                    if (components[j] == null)
                    {
                        prop.DeleteArrayElementAtIndex(j - r);
                        r++;
                    }
                } 
                serializedObject.ApplyModifiedProperties();
            }
        }
    }
}

此为编辑器脚本

使用方法：

方法二：

using UnityEngine;
using UnityEditor; 
public class DeleteMissingScripts
{
    [MenuItem("Edit/Cleanup Missing Scripts")]
    static void CleanupMissingScripts()
    {
        for (int i = 0; i < Selection.gameObjects.Length; i++)
        {
            var gameObject = Selection.gameObjects[i];
 
            // We must use the GetComponents array to actually detect missing components
            var components = gameObject.GetComponents<Component>();
 
            // Create a serialized object so that we can edit the component list
            var serializedObject = new SerializedObject(gameObject);
            // Find the component list property
            var prop = serializedObject.FindProperty("m_Component");
 
            // Track how many components we've removed
            int r = 0;
 
            // Iterate over all components
            for (int j = 0; j < components.Length; j++)
            {
                // Check if the ref is null
                if (components[j] == null)
                {
                    // If so, remove from the serialized component array
                    prop.DeleteArrayElementAtIndex(j - r);
                    // Increment removed count
                    r++;
                }
            } 
            // Apply our changes to the game object
            serializedObject.ApplyModifiedProperties();
            EditorUtility.SetDirty(gameObject);
        }
    }
}
 

建议采取方法二

已知两种方法可能会出现某些错误，

方法二运行几次会自动修复（方法一未测试）

以上为个人经验，希望能给大家一个参考，也希望大家多多支持自由互联。如有错误或未考虑完全的地方，望不吝赐教。
