如何使用代码更新统一资产文件

Question

我想通过GUI操作在调试和发布之间切换环境。

一些第三方SDK配置需要在.asset文件中更改。我使用 AssetDatabase

[MenuItem("TEST/Switch Environment/Switch to Dev")]
public static void Switch2Dev()
{

    object []data = AssetDatabase.LoadAllAssetsAtPath ("./Assets/_ThirdParty/Photon/PhotonUnityNetworking/Resources/PhotonServerSettings.asset");

    if (data == null || data.Length == 0) {
        Debug.Log ("cannot read content from PhotonServerSettings.asset");
        return;
    }
    Photon.Pun.ServerSettings settings = data [0] as Photon.Pun.ServerSettings;

    settings.AppSettings.Server = "10.10.10.10";
    settings.AppSettings.Port = 4530;
    settings.AppSettings.Protocol = ExitGames.Client.Photon.ConnectionProtocol.Tcp;
    AssetDatabase.SaveAssets ();
}

和.asset文件的内容：

%YAML 1.1
%TAG !u! tag:unity3d.com,2011:
--- !u!114 &11400000
MonoBehaviour:
  m_ObjectHideFlags: 0
  m_PrefabParentObject: {fileID: 0}

  m_EditorHideFlags: 0
  m_Script: {fileID: 11500000, guid: 9f3758f8f58fdef43803eb9be1df0608, type: 3}

  - ReceivePosition

  - ReceiveDressUpCommand
  - ReceiveLoadDressUpCommand
  - ReceiveSendLoginCommand
  - ReceiveSetActiveMyself
  DisableAutoOpenWizard: 1
  ShowSettings: 1

当我单击切换到开发按钮时，内容无法成功更新。我还尝试添加以下代码：

EditorUtility.SetDirty(data[0]);

也无法成功更新。如果无法使用此方法，我将使用StreamWriter和StreamReader更新txt文件。...

[编辑版本]它根本无法工作。

[MenuItem("TEST/Switch Environment/Switch to Prod")]
public static void Switch2Prod()
{
    UnityEngine.Object []data = AssetDatabase.LoadAllAssetsAtPath("./Assets/_ThirdParty/Photon/PhotonUnityNetworking/Resources/PhotonServerSettings.asset");

    if (data == null || data.Length == 0) {
        GVRChat.Log ("cannot read content from PhotonServerSettings.asset");
        return;
    }
    EditorUtility.SetDirty(data[0]);
    Photon.Pun.ServerSettings settings = data [0] as Photon.Pun.ServerSettings;
    settings.AppSettings.Server = "2.2.2.2";
    settings.AppSettings.Port = 4530;
    settings.AppSettings.Protocol = ExitGames.Client.Photon.ConnectionProtocol.Tcp;

    AssetDatabase.SaveAssets ();
    AssetDatabase.Refresh ();
}
