基本结构就是：

java命令 java参数 加载目录 加载lib文件 加载核心 启动参数

下面我们来一个一个解释：

java命令：这么说可能不太恰当，总之就是启动java的，如果你配置好了环境变量，那么可以直接使用"java"来代替，不过这样会有后台输出的（就是那个黑框框），如果觉得太难看，可以使用javaw。如果你不知道使用者有没有配置环境变量，那么推荐使用java文件的路径，一般在安装文件夹的bin文件夹里。里面会有java.exe和javaw.exe，用法和上面一样。不过这里有一点要注意= =，如果文件路径有空格，需要用双引号括起来，不然会提示找不到文件（如果不知道为什么= =，你还是先去普及一下基本知识吧）
例如：/usr/lib/jvm/java-8-oracle/bin/java

java参数：其实就是内存大小，这个就不需要解释了吧？（别问我最小内存是什么，自己百度去）
例如：-Xmx 1G

加载目录：这部分其实是和加载lib文件一起的，只不过分开讲更简明，主要内容就是 -Djava.library.path=你的MC版本文件路径-natives=natives文件夹的位置
例如： -Djava.library.path=/home/bluek404/.minecraft/versions/1.6.4/1.6.4-natives=4372492257234

加载lib文件：这个就略复杂了，需要涉及到读取json，如果你是易语言= =，那么慢慢翻去吧。如果是其他语言，一般都有例程的，就不需要我详细解释了。如果你需要手动解析= =，就是吧json文件里的那一堆字母换成文件路径就可以了
例如：-cp /home/bluek404/.minecraft/libraries/XXXXX;另一个lib文件;又是一个lib文件

加载核心：这个一般跟在加载lib的后面，其实就是吧minecraft.jar加载了，当然这个部分其实是和加载lib文件一起的，但是分开来讲就是为了防止混淆（虽然混起来也没什么问题），结构和加载lib文件是一样的
例如：/home/bluek404/.minecraft/versions/1.6.4/1.6.4.jar

启动参数：这个也是靠读取json得来的，一般就是json文件上面那一段，大概结构是这样的：net.minecraft.client.main.Main --用户名 --session token 正版账户的密匙（这一部分的获取可以看我发的帖子） -version 游戏版本 --gameDir .minecraft文件夹的位置 -assetsDir assets文件夹的位置 -更多的启动参数(这一部分可以从json文件里读取，一般是forge的参数)
例如：net.minecraft.client.main.Main --Bluek404 --session token a11b252ch5eh234fi283wr8:1fn3si3sks9jsiww32sh -version 1.6.4 --gameDir /home/bluek404./minecraft -assetsDir /home/bluek404./minecraft/assets/virtual/legacy


以上纯属个人见解，如有错误，欢迎指出

懒得看啊，太多，还有，顶一下。。。。。。

这贴不错我喜欢

其实本来不想写这么多的。。。但是一句半句怕解释不明白。。。

=A=斑竹求混脸熟

好吧，我看出来了，这是Bluek
= =

嘛=A=
                           

技术宅求混脸熟

求助能读JSON但启动不了{:10_501:}
读出的JSON

你打开CMD 然后运行这个看看有什么报错
记得吧前面的"C:\Program Files (x86)\Java\jre7\bin\javaw.exe"
替换成java

求大神怎么破

你应该少加载了个lib，貌似是lwjgl

感谢大神{:10_512:}

这个倒是搞定了，但是很明显，我在XP下会出现因为命令行过长而导致游戏无法运行的情况，WIN7到没有这问题，难道要用Json吗…………

这和json应该没关系= =
应该是系统限制了，java版本相同？

大大，那个session你说的那个帖子链接能发下？

顿时恍然大悟！C语言写启动器不是梦！

唯一不会的就是读取json.......我是学java的，求详细说明怎么读取json啊

这个必须赞一个

比较强哈

弱弱的问一句，json在哪啊

-cp后面填什么啊！！！

楼主不需要发基础整合！我直接启动器重新下了1.10.2和forge一点都不报错！也不麻烦
