[Unity]游戏内查看BundleVersion版本号.

转载自StackOverFlow

基本原理是[InitializeOnLoad]
在每次有变动完毕之后会执行BundleVersionChecker
在BundleVersionChecker中会自动判断版本号是否变更,如果变更会把新的版本号写入cs文件.
从而实现在游戏中获取版本号.

我直接贴代码吧

using System.IO;using UnityEditor;using UnityEngine;[InitializeOnLoad]public class BundleVersionChecker{    /// <summary>    /// Class name to use when referencing from code.    /// </summary>    private const string ClassName = "CurrentBundleVersion";    // cs文件路径    private const string TargetCodeFile = "Assets/GameResources/Script/Config/" + ClassName + ".cs";    static BundleVersionChecker()    {        string bundleVersion = PlayerSettings.bundleVersion;        string lastVersion = CurrentBundleVersion.version;        if (lastVersion != bundleVersion)        {            Debug.Log("Found new bundle version " + bundleVersion + " replacing code from previous version " + lastVersion + " in file \"" + TargetCodeFile + "\"");            CreateNewBuildVersionClassFile(bundleVersion);        }    }    private static string CreateNewBuildVersionClassFile(string bundleVersion)    {        using (StreamWriter writer = new StreamWriter(TargetCodeFile, false))        {            try            {                string code = GenerateCode(bundleVersion);                writer.WriteLine("{0}", code);            }            catch (System.Exception ex)            {                string msg = " threw:\n" + ex.ToString();                Debug.LogError(msg);                EditorUtility.DisplayDialog("Error when trying to regenerate class", msg, "OK");            }        }        return TargetCodeFile;    }    /// <summary>    /// Regenerates (and replaces) the code for ClassName with new bundle version id.    /// </summary>    /// <returns>    /// Code to write to file.    /// </returns>    /// <param name='bundleVersion'>    /// New bundle version.    /// </param>    private static string GenerateCode(string bundleVersion)    {        string code = "public static class " + ClassName + "\n{\n";        code += System.String.Format("\tpublic static readonly string version = \"{0}\";", bundleVersion);        code += "\n}\n";        return code;    }}

// 另外一个文件public static class CurrentBundleVersion{    public static readonly string version = "0.8.5";}

实际调用

if (CurrentBundleVersion != "0.8.4"){    // do migration stuff}
