切换到手册
public static T FindObjectOfType ();
public static T FindObjectOfType (bool includeInactive);
public static Object FindObjectOfType (Type type);
public static Object FindObjectOfType (Type type, bool includeInactive);

参数

type要查找的对象类型。

返回

T Object The first active loaded object that matches the specified type. It returns null if no Object matches the type.

描述

返回第一个类型为 type 的已加载的激活对象。

Object.FindObjectOfType will not return Assets (meshes, textures, prefabs, ...) or inactive objects. It will not return an object that has HideFlags.DontSave set.

Please note that this function is very slow. It is not recommended to use this function every frame. In most cases you can use the singleton pattern instead.
