的Minecraft啓動：在的java.library.path

Question

沒有LWJGL我想使用此代碼從我的Qt程序啓動的Minecraft：

params.append("java -Xmx1024M "); 
params.append("-Djava.library.path=" + QDir::toNativeSeparators("C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/org/lwjgl/lwjgl/lwjgl-platform/2.9.1/") + " "); 
params.append("-cp C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/java3d/vecmath/1.3.1/vecmath-1.3.1.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/net/sf/trove4j/trove4j/3.0.3/trove4j-3.0.3.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/ibm/icu/icu4j-core-mojang/51.2/icu4j-core-mojang-51.2.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/net/sf/jopt-simple/jopt-simple/4.5/jopt-simple-4.5.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/paulscode/codecjorbis/20101023/codecjorbis-20101023.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/paulscode/codecwav/20101023/codecwav-20101023.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/paulscode/libraryjavasound/20101123/libraryjavasound-20101123.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/paulscode/librarylwjglopenal/20100824/librarylwjglopenal-20100824.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/paulscode/soundsystem/20120107/soundsystem-20120107.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/io/netty/netty-all/4.0.10.Final/netty-all-4.0.10.Final.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/google/guava/guava/15.0/guava-15.0.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/org/apache/commons/commons-lang3/3.1/commons-lang3-3.1.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/commons-io/commons-io/2.4/commons-io-2.4.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/net/java/jinput/jinput/2.0.5/jinput-2.0.5.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/net/java/jutils/jutils/1.0.0/jutils-1.0.0.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/google/code/gson/gson/2.2.4/gson-2.2.4.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/com/mojang/authlib/1.2/authlib-1.2.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/org/apache/logging/log4j/log4j-api/2.0-beta9/log4j-api-2.0-beta9.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/org/apache/logging/log4j/log4j-core/2.0-beta9/log4j-core-2.0-beta9.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/org/lwjgl/lwjgl/lwjgl/2.9.1-nightly-20131120/lwjgl-2.9.1-nightly-20131120.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/org/lwjgl/lwjgl/lwjgl_util/2.9.1-nightly-20131120/lwjgl_util-2.9.1-nightly-20131120.jar;C:/Users/sercinci/AppData/Roaming/.minecraft/libraries/tv/twitch/twitch/5.12/twitch-5.12.jar;"); 
params.append(QDir::toNativeSeparators("C:/Users/sercinci/AppData/Roaming/.minecraft/versions/1.7.4/1.7.4.jar") + " "); 
params.append("net.minecraft.client.main.Main "); 
params.append("--username " + sUsername + " "); 
params.append("--version 1.7.4 "); 
params.append("--assetIndex 1.7.4 "); 
params.append("--assetsDir " + QDir::toNativeSeparators("C:/Users/sercinci/AppData/Roaming/.minecraft/assets") + " "); 
params.append("--userProperties {} "); 
params.append("--gameDir C:/Users/sercinci/AppData/Roaming/.minecraft "); 
params.append("--accessToken " + sLogID + ""); 

的響應是：No such file or directory。

使用直接在cmd中相同的代碼（在互聯網上和堆棧溢出過相同的發現）：

它說：

中的java.library.path沒有LWJGL

我試過用%appdata%路徑，1.7.4和1.7.10版本，並檢查所有的路徑和庫版本。我已經檢查了所有其他相關問題，但他們沒有解決我的問題。

謝謝你的幫助。

Answer 1

您必須找到正確版本的庫。默認的Minecraft啓動程序從minecraft網站更新庫，所以您使用的代碼可能不是最新的。要獲得正確的庫，請執行此操作。

• 打開默認啓動
• 創建一個新的配置文件
• 更改Java可執行文件的東西，將它

@echo off 
echo %* 
pause 

打印出所有的參數，如 .bat文件與此
• 「遊戲輸出」選項卡應顯示用於運行Java的所有參數

然後你可以通過它找到所有的庫。我建議使用自己的目錄（不是.minecraft）並使用自己的啓動器下載這些庫，這樣就不必一直重新檢查這些庫。

This是Mojang的下載資產和庫的API頁面，所以它可能會有所幫助。
