Unity编辑器（Editor）的问题全解以及使用

最近写了一个Unity优化工具，主要是搜索某一个文件夹中所有的场景和预设。如果是场景的话，就遍历场景中的所有对象，观察对象身上是否绑定了AudioListener组件，如果有的话移除该组件并保存场景。如果是预设的话，就遍历预设中的所有对象，观察预设中的对象是否绑定AudioListener组件，如果有的话移除该组件。

脚本如下：

增加：过滤非指定资源的执行（动画代码修改：）

2，Unity编辑器不用实例化Prefab获取，删除，更新组件：

3，根据对象名字，标签或者类型查找某一个文件夹中所有对象的路径

4，游戏运行的时候对场景中对象的修改，通过代码控制保存的方法

5，脚本自动定位选择Hierarchy或Project下的对象

6，Unity编辑器扩展（自动保存当前打开的场景）

https://blog.csdn.net/crazyape/article/details/78803549

7，移除某个对象身上绑定的组件：

DestroyImmediate(audios[i].GetComponent<AudioListener>());

为了安全起见，我们移除的时候要添加一个参数：

对于Prefab身上的组件我们不能用DestroyImmediate(audios[i].GetComponent<AudioListener>());

方法，会报错。用DestroyImmediate(audios[i].GetComponent<AudioListener>(), true);方法
