Unity AssetDatabase.FindAssets

Unity里的AssetDataBase简单介绍

UnityEditor：

提示：AssetDatabase.FindAssets

using UnityEngine;
using UnityEditor;
using System.IO;

/*
1.编译器代码：继承自Editor，只适用于Unity编辑器中执行代码
2.[MenuItem("......")] 用于修饰在编译器产生菜单
3.AssetDatabase：只适用于编译器操作资源
4.StreamingAssets：Unity特殊目录之一，该目录中文件不会被压缩，适合于移动端读取资源（只读）（PC端可写入）
5.Application.persistentDataPath: 可以在运行时进行读写，Unity外部目录（安装软件时才产生）
