AssetDatabase.AddObjectToAsset

参数

描述

将objectToAdd添加到path处的现有资源。

请注意，您应该只将对象添加到“.asset”资源中，例如导入的模型或纹理对象将丢失其数据。

所有路径相对于项目文件夹。

注意：您不能添加游戏对象；请改用PrefabUtility。

using UnityEditor;

public class AddObjectToAssetPathExample
{
    [MenuItem("AssetDatabase/AddObjectToAssetPathExample")]
    static void AddObjectToPathExample()
    {
        // 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 dummyObject = ScriptableObject.CreateInstance<DummyObject>();
        dummyObject.name = "My scriptable asset";

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

        // Get the path of the scriptable object asset
        string dummyObjectPath = AssetDatabase.GetAssetPath(dummyObject);

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

        // Serializing the changes in memory to disk
        AssetDatabase.SaveAssets();

        // Print the path of the created asset
        Debug.Log(AssetDatabase.GetAssetPath(dummyObject));
    }
}

// The DummyObject class used in the example above
public class DummyObject : ScriptableObject
{
    public string objectName = "dummy";
}

参数

描述

将objectToAdd添加到由assetObject标识的现有资源。

注意：在调用 AddObjectToAsset 之前，如果objectToAdd已存在于磁盘上，将会生成错误（例如，尝试将“MyMaterial”添加到现有资源）：“由于材质'MyMaterial'已经是'Assets/MyMaterial.mat'处的资源，因此无法将其添加到资源文件中！”

注意：您必须将内存中的更改序列化到磁盘。
这是因为必须将内存中修改过的资源保存到磁盘。
如果未执行此操作，将会产生不一致的结果警告，因为对资源的内存修改将会丢失。
