Resources.FindObjectsOfTypeAll

切换到手册
public static Object[] FindObjectsOfTypeAll (Type type);

参数

type 搜索时要匹配的类的类型。

返回

Object[] 对象数组,其类为 type 或派生自 type

描述

返回所有类型为 type 的对象的列表。

该函数可以返回任何类型的已加载的 Unity 对象,包括游戏对象、预制件、材质、网格、纹理等。此外,它还会列出内部内容,因此在处理返回的对象时要格外 小心。 与 Object.FindObjectsOfType 相反,该函数还会列出禁用的对象。

请注意,该函数的运行速度非常缓慢,不建议在每帧中使用。

public class ExampleScript : MonoBehaviour { // This script displays the number of allocated Unity objects by type. // This is useful for finding leaks. Knowing the type of object // (mesh, texture, sound clip, game object) that is getting leaked is // the first step. You could then print the names of all leaked assets of that type.
