Application.streamingAssetsPath和WebGL构建 [英] Application.streamingAssetsPath and WebGL build

问题描述

在我正在处理的项目中，StreamingAssets目录中有两个json文件.处理这些脚本的脚本在Standalone PC版本中可以完美运行，而在WebGL版本中则完全不起作用.

In a project I'm working on I have two json files in the StreamingAssets directory. The script that handles them works perfectly in a Standalone PC build but doesn't work at all in a WebGL one.

我收到找不到文件！"消息根据脚本:

I'm getting the "Cannot find file!" message according to the script:

    else if (!File.Exists (filePath))
    {
        Debug.LogError ("Cannot find file!"); 
    }

我得到了使用Unity网站上的脚本API所描述的WWW类的答案，该地址位于以下地址: https://docs.unity3d.com/ScriptReference/Application-streamingAssetsPath.html

I was given the answer to use the WWW class as described in the scripting API on Unity Technologies site at this address: https://docs.unity3d.com/ScriptReference/Application-streamingAssetsPath.html

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "MyFile");
    public string result = "";
    IEnumerator Example() {
        if (filePath.Contains("://")) {
            WWW www = new WWW(filePath);
            yield return www;
            result = www.text;
        } else
            result = System.IO.File.ReadAllText(filePath);
    }
}

我很乐意这样做，但是我在编码方面太新了，我需要一些解释.我现在的第一个问题是:这行中的我的文件" 字符串是什么

I would gladly do that but I'm too new at coding and I need some explanations. The first question I have for now is: what is this "my file" string in the line

    public string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "MyFile");

我应该在那写什么?是网址吗?如果是网址，该网址是什么?

What am I supposed to write there? Is it a url? And if it is a url, the url of what?

如果有人可以握住我的手，并引导我了解这一点，我将不胜感激！谢谢！

I would be very grateful is someone could hold my hand and guide me into understanding this! Thank you!

(这是我的第一个问题；我希望我没有犯错，因为我还不知道这个地方的工作方式.)

(This is my first question here; I hope I haven't made mistakes as I don't know how this place works yet.)

推荐答案

我现在的第一个问题是:这个我的文件"字符串在哪里 线

The first question I have for now is: what is this "my file" string in the line

这应该是文件名，尽管它缺少扩展名.您应该添加.例如， .txt ， .jpg ， png ....

That's supposed to be the name of the file.Although, it is missing it's extension name. You should add that. For example, .txt, .jpg, png....

我应该在那里写什么?是网址吗?如果是网址， 的网址是什么?

What am I supposed to write there? Is it a url? And if it is a url, the url of what?

您只应该将扩展名写在"MyFile" 所在的文件名上.

You are just supposed to write the name of the file with the extension name where "MyFile" is.

示例使用:

在您的项目中，创建一个名为" StreamingAssets "的文件夹.

In your Project, you create a folder called "StreamingAssets".

假设您有一个名为"Anne.txt" 的文件，并且该文件位于"StreamingAssets" 中.文件夹，这应该是您的路径:

Let's say that you have a file named "Anne.txt", and the file is inside the "StreamingAssets". folder, this should be your path:

public string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "Anne.txt");

---

现在，我们将" Anne.txt "文件夹放置在名为" Data "的文件夹中，然后将其放置在" StreamingAssets "中>"文件夹，它应如下所示:" StreamingAssets/Data/Anne.txt ".

---

Now let's say that the "Anne.txt" folder is placed in a folder called "Data" which is then in the "StreamingAssets" folder, it should look like this: "StreamingAssets/Data/Anne.txt".

您的路径应为:

public string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "Data");
filePath = System.IO.Path.Combine(filePath , "Anne.txt");

就是这样.这里没什么复杂的.然后，将该路径字符串与WWW一起使用.

That's it. Nothing complicated here. You then use that path string with WWW.

另外，您的if (filePath.Contains("://"))应该是if (filePath.Contains ("://") || filePath.Contains (":///")).

编辑

如果要加载多个文件，我将该函数简化为该函数，以便将文件名作为参数.

If you have multiple files you want to load, I simplified that function into this so that it takes the file name as parameter.

IEnumerator loadStreamingAsset(string fileName)
{
    string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, fileName);

    string result;
    if (filePath.Contains("://") || filePath.Contains(":///"))
    {
        WWW www = new WWW(filePath);
        yield return www;
        result = www.text;
    }
    else
        result = System.IO.File.ReadAllText(filePath);
}

现在，假设您有3个文件，分别是" Anne.txt "，" AnotherAnne.txt "和" OtherAnne.txt " "放置在" StreamingAssets "文件夹中，则可以使用以下代码加载它们:

Now, let's say that you have 3 files called "Anne.txt", "AnotherAnne.txt" and "OtherAnne.txt" placed in the "StreamingAssets" folder, you can load them with the code below:

StartCoroutine(loadStreamingAsset("Anne.txt"));

StartCoroutine(loadStreamingAsset("AnotherAnne.txt"));

StartCoroutine(loadStreamingAsset("OtherAnne.txt"));
