Unity Asset DataBase Editor

本篇文章纪录和Asset DataBase相关，可以通过脚本方式控制。

Importing an Asset

using UnityEngine;
using UnityEditor;

public class ImportAsset {
    [MenuItem ("AssetDatabase/ImportExample")]
    static void ImportExample ()
    {
        AssetDatabase.ImportAsset("Assets/Textures/texture.jpg", ImportAssetOptions.Default);
    }
}

ImportAssetOptions选项：
Default 默认导入选项。
ForceUpdate 由用户发起的资源导入。
ForceSynchronousImport 同步导入所有资源。
ImportRecursive 导入文件夹时，也要导入其中的所有内容。
DontDownloadFromCacheServer 强制完全重新导入，但不从缓存服务器下载资源。
ForceUncompressedImport 强制资源以版本工具的未压缩形式导入。

Loading an Asset

using UnityEngine;
using UnityEditor;

public class ImportAsset {
    [MenuItem ("AssetDatabase/LoadAssetExample")]
    static void ImportExample ()
    {
        Texture2D t = AssetDatabase.LoadAssetAtPath("Assets/Textures/texture.jpg", typeof(Texture2D)) as Texture2D;
    }
}

有关AssetDataBase的文件操作

public class AssetDatabaseIOExample {
    [MenuItem ("AssetDatabase/FileOperationsExample")]
    static void Example ()
    {
        string ret;
        
        // 创建
        Material material = new Material (Shader.Find("Specular"));
        AssetDatabase.CreateAsset(material, "Assets/MyMaterial.mat");
        if(AssetDatabase.Contains(material))
            Debug.Log("Material asset created");
        
        // 重命名
        ret = AssetDatabase.RenameAsset("Assets/MyMaterial.mat", "MyMaterialNew");
        if(ret == "")
            Debug.Log("Material asset renamed to MyMaterialNew");
        else
            Debug.Log(ret);
        
        // 创建文件夹
        ret = AssetDatabase.CreateFolder("Assets", "NewFolder");
        if(AssetDatabase.GUIDToAssetPath(ret) != "")
            Debug.Log("Folder asset created");
        else
            Debug.Log("Couldn't find the GUID for the path");
        
        // 移动
        ret = AssetDatabase.MoveAsset(AssetDatabase.GetAssetPath(material), "Assets/NewFolder/MyMaterialNew.mat");
        if(ret == "")
            Debug.Log("Material asset moved to NewFolder/MyMaterialNew.mat");
        else
            Debug.Log(ret);
        
        // 复制
        if(AssetDatabase.CopyAsset(AssetDatabase.GetAssetPath(material), "Assets/MyMaterialNew.mat"))
            Debug.Log("Material asset copied as Assets/MyMaterialNew.mat");
        else
            Debug.Log("Couldn't copy the material");
        // 手动刷新数据库以通知更改
        AssetDatabase.Refresh();
        Material MaterialCopy = AssetDatabase.LoadAssetAtPath("Assets/MyMaterialNew.mat", typeof(Material)) as Material;
        
        // 移到垃圾箱
        if(AssetDatabase.MoveAssetToTrash(AssetDatabase.GetAssetPath(MaterialCopy)))
            Debug.Log("MaterialCopy asset moved to trash");
        
        // 删除
        if(AssetDatabase.DeleteAsset(AssetDatabase.GetAssetPath(material)))
            Debug.Log("Material asset deleted");
        if(AssetDatabase.DeleteAsset("Assets/NewFolder"))
            Debug.Log("NewFolder deleted");
        
        // 进行所有更改后刷新 AssetDatabase
        AssetDatabase.Refresh();
    }
}
