解决 unity 生成 android apk read Resources

TextAsset t = (TextAsset)Resources.Load("skill2");
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(t.text.ToString().Trim());

        XmlElement n = (XmlElement)xmlDoc.SelectSingleNode("/datas/data[@skillID='1002']");
        if (n != null)
        {
            print("+++++++++++++++++++++++++++++++++++++++++++++++++");
            data += n.GetAttribute("skillID");

解决 unity 生成 android apk read Resources

试了很多方法都找不到 unity 的目录，，最后没有办法了，放在 Resources 目录里。。。

发觉只能读不能写，，汗，，，白费了，又重新找。。。。

找到了 android 工程模板了。。。。

Unity\Editor\Data\PlaybackEngines\androidplayer\

就像 web 模板一样

把它复制出来，导入eclipse

好了，只能拼 android 基础了。。。。

做好放在

解决了，，，下面说下步骤

test.txt 路径如图

void readFile(string file)
    {
        path = "jar:file://" + Application.dataPath + "!/assets/" + file;

        if (File.Exists(path))
        {
            stringToEdit = "yes";
        }
        else
        {
            stringToEdit = "no";

            WWW www = new WWW(path);
            while (!www.isDone) { }

            stringToEdit += " " + www.text;

        }
    }

不知道为什么 File.Exists(path)会检测不到文件，，，不过能读取就可以了

说下

Application.persistentDataPath 是指向 android /data/data/xxx.xxx.xxx/files/

Application.dataPath 是指向 /data/app/xxx.xxx.xxx.apk

汗：http://game.ceeger.com/Manual/StreamingAssets.html 这是unity圣典翻译好了，写得很详细了，，，
难怪会检测不到文件..现在还在解决解包问题
然后复制到 Application.persistentDataPath

/*
 * 没有测试过
ICSharpCode.SharpZipLib.Zip.FastZip zip = new ICSharpCode.SharpZipLib.Zip.FastZip();
zip.CreateZip("C:\\foo.zip", "C:\\待压缩的文件夹", true, ""); //第三个参数表示是否压缩子文件夹
zip.ExtractZip("C:\\foo.zip", "C:\\压缩后存放的文件夹", "");
如果我们只想压缩目录中的一个或部分文件，或者我们只想解压文件中的一个或部分文件，怎么办呢？那就得把最后一个参数用上，它是字符串类型的正则表达式，比如只压缩 ini 文件用："^.*(.ini)$"。
