这些是我编程的开端 :) 我从 Visual Basic 开始，现在我在做 C++。这适用于想知道如何制作 Minecraft Launcher 的任何人。
首先，您必须下载“游戏文件”，所有内容都有据可查HERE。然后你就可以开始思考如何开始游戏了。
您将需要访问权限和客户端令牌 我稍微改进了代码：
Imports System.IO
Imports System.Net
Imports System.Web.Script.Serialization ' Add Reference System.Web.Extensions
Module Program
Public Function Authenticate(ByRef username As String, ByRef password As String) As String
Dim UUID As String = Guid.NewGuid.ToString()
Dim Request As HttpWebRequest = DirectCast(WebRequest.Create("https://authserver.mojang.com/authenticate"), HttpWebRequest)
Request.ContentType = "application/json"
Request.Method = "POST"
Using Writer = New StreamWriter(Request.GetRequestStream())
Dim Json As String = ("{ 'agent': {'name': 'Minecraft', 'version': 1}, 'username': '" + username + "', 'password': '" + password + "', 'clientToken': '" + UUID + "', 'requestUser': true }").Replace("'", Chr(34))
Writer.Write(Json)
Writer.Flush()
Writer.Close()
Dim Response = DirectCast(Request.GetResponse(), HttpWebResponse)
Using Reader = New StreamReader(Response.GetResponseStream())
Return Reader.ReadToEnd()
End Using
End Using
End Function
Sub Main()
Dim Response As String = Authenticate("username", "password")
Dim Serializer As JavaScriptSerializer = New JavaScriptSerializer()
Dim Dictionary As Dictionary(Of String, Object) = Serializer.Deserialize(Of Dictionary(Of String, Object))(Response)
Dim AccessToken As String = Dictionary("accessToken")
Dim ClientToken As String = Dictionary("clientToken")
Console.WriteLine(AccessToken)
Console.WriteLine(ClientToken)
Console.Read()
End Sub
End Module
在此代码中，您将 HTTP POST 请求发送到 mojang 身份验证服务器，然后将响应解析为带有 JavaScriptSerializer 的 json。访问令牌和客户端令牌存储在AccessToken 和ClientToken 变量中。 Mojang 身份验证记录在HERE。然后我建议你从System.Diagnostics 创建Process 并像这样开始：
Public Sub LaunchMinecraft(ByRef AccessToken As String, ByRef ClientToken As String)
Dim Xmx As String = "4G"
Dim Xms As String = "2G"
Dim Title As String = "My Minecraft Instance"
Dim Version As String = "1.7.10"
Dim AssetIndex As String = "..." ' AssetIndex obtained from mojang server
Dim Username As String = "..." ' Minecraft username obtained from mojang server
Dim Libraries As String = "..." ' Paths to all libraries separated by ;
Dim JavaProcess As Process = New Process()
JavaProcess.StartInfo.UseShellExecute = False
JavaProcess.StartInfo.CreateNoWindow = False
JavaProcess.StartInfo.FileName = "..." ' Path to javaw.exe or java.exe
JavaProcess.StartInfo.Arguments = "-XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump" +
" -Xmx" + Xmx +
" -Xms" + Xms +
" -Djava.library.path=.//bin/natives" +
" -Dminecraft.client.jar=.//bin/modpack.jar" +
" -Dminecraft.applet.TargetDirectory=.//" +
" -cp .//bin/modpack.jar;" + Libraries + ";.//bin/minecraft.jar" +
" -XX:+UnlockExperimentalVMOptions" +
" -XX:+UseG1GC -XX:G1NewSizePercent=20" +
" -XX:G1ReservePercent=20" +
" -XX:MaxGCPauseMillis=50" +
" -XX:G1HeapRegionSize=16M" +
" net.minecraft.launchwrapper.Launch" +
" --gameDir .//" +
" --username " + Username +
" --assetsDir ..//..//..//cache/assets" +
" --assetIndex " + AssetIndex +
" --version " + Version +
" --uuid " + ClientToken +
" --accessToken " + AccessToken +
" --userProperties {}" +
" --userType mojang" +
" --tweakClass cpw.mods.fml.common.launcher.FMLTweaker" +
" --title " + Title
JavaProcess.Start()
End Sub
此代码未经测试，也有相对路径。这只是一个例子。请注意，这是针对修改后的我的世界。希望对您有所帮助！
