AssetDatabase.GetTypeFromPathAndFileID

参数

返回

Type The object's type.

描述

Gets an object's type from an Asset path and a local file identifier.

The following script example shows how to get the types of a nested asset. A material asset is added to a scriptable object asset (in this case called DummyObject), and the types of these two assets are extracted by calling GetTypeFromPathAndFileID.

using UnityEngine;
using UnityEditor;

public class GetTypeFromPathAndFileIDExample
{

    // Create a menu item under the GameObject menu.
    [MenuItem("AssetDatabase/GetTypeFromPathAndFileIDExample")]
    static void GetNestedType()
    {
        // Create a simple material object.
        Material material = new Material(Shader.Find("Specular"));
        material.name = "My material";

        // Create an instance of a simple scriptable object
        DummyObject scriptableObject = ScriptableObject.CreateInstance<DummyObject>();
        scriptableObject.name = "My scriptable object";

        // Create the scriptable object asset
        AssetDatabase.CreateAsset(scriptableObject, "Assets/myScriptableObject.asset");

        // Add the material to the scriptable object asset
        AssetDatabase.AddObjectToAsset(material, scriptableObject);
        AssetDatabase.SaveAssets();

        // Get the path of the created asset
        string scriptableObjectPath = AssetDatabase.GetAssetPath(scriptableObject);

        // Get the GUID and the local file identifier of the scriptable object and the material.
        string materialGUID, scriptableObjectGUID;
        long materialFileID, scriptableObjectFileID;
        AssetDatabase.TryGetGUIDAndLocalFileIdentifier(scriptableObject, out scriptableObjectGUID, out scriptableObjectFileID);
        AssetDatabase.TryGetGUIDAndLocalFileIdentifier(material, out materialGUID, out materialFileID);

        // Print type, local file identifier and path of the two assets.
        // Notice that the nested assets has the same path as the parent but different local file identifier.
        Debug.Log(scriptableObject.name+" type: "+ AssetDatabase.GetTypeFromPathAndFileID(scriptableObjectPath, scriptableObjectFileID) + ", fileID: "+scriptableObjectFileID+", path: " + scriptableObjectPath);
        Debug.Log(material.name+" type: "+ AssetDatabase.GetTypeFromPathAndFileID(scriptableObjectPath, materialFileID) + ", fileID: " + materialFileID + ", path: " + scriptableObjectPath);
    }
}

public class DummyObject : ScriptableObject {
    public string objectName = "dummy";
}
