安装后将文件从Resources/StreamingAssets复制到Application.persistentDataPath [英] Copy files from Resources/StreamingAssets to Application.persistentDataPath upon installation

问题描述

我有一个txt文件，其中包含游戏中我的地图的数据.问题是该文件存储在Application.persistentDataPath中，因此即使从我的android设备(创建的地图创建者)，我也可以对其进行更改，因此如何将我在PC上创建的txt文件包含在基本地图中，并使其显示在persistentDataPath中安装应用程序时我的Android设备是什么?

I have txt file which contains data for my maps in game. Problem is that file is stored in Application.persistentDataPath so I can change it even from my android device (created map creator) so how can I include txt file which I created on my PC with basic maps and make it appear in persistentDataPath on my android device when I install application?

推荐答案

您可以将文件从Editor文件夹放入Resources文件夹，然后使用Resources API进行读取.

You can put the file in the Resources folder from the Editor folder then read with the Resources API.

TextAsset txtAsset = (TextAsset)Resources.Load("textfile", typeof(TextAsset));
string tileFile = txtAsset.text;

您可以使用

You can check if this is the first time the app is running with this. After that you can copy the loaded data to the Application.persistentDataPath directory.

众所周知，资源"文件夹会增加加载时间.我建议您不要使用它，但这是一个值得了解的选项.

The Resources folder is known to increase loading times. I suggest you don't use it but it's an option that's worth knowing.

将文件放在 StreamingAssets 文件夹中，然后使用WWW或UnityWebRequest API和Application.streamingAssetsPath作为路径读取文件，然后将其复制到Application.persistentDataPath.

Put the file in StreamingAssets folder then read it with the WWW or UnityWebRequest API and Application.streamingAssetsPath as the path then copy it to Application.persistentDataPath.

从StreamingAssets加载:

IEnumerator ReadFromStreamingAssets()
{
    string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "MyFile");
    string result = "";
    if (filePath.Contains("://") || filePath.Contains(":///"))
    {
        UnityEngine.Networking.UnityWebRequest www = UnityEngine.Networking.UnityWebRequest.Get(filePath);
        yield return www.SendWebRequest();
        result = www.downloadHandler.text;
    }
    else
        result = System.IO.File.ReadAllText(filePath);
}

然后将其保存到persistentDataPath:

then save it to persistentDataPath:

File.WriteAllText(Application.persistentDataPath + "data/MyFile.txt", result);
