I am trying to make a game client that is similar to one already made so I tried to decompile the program to see how they did it to give myself ideas. The issue is, when it was decompiled I found that it was fully obfuscated. Now, I've read up on this and have listed the possible methods that people have said work:

-Refactoring with an IDE (Which IDE offers the best refactoring features?)

-Deobfuscate with a program like JOB

-Attempt to read and interpret the javabyte code

I used jd-gui to decompile the code. A large amount of the classes are comprised mainly of code like this:

`// Byte code:
//   0: getstatic 171   com/Methodxe:Methodh    I
//   3: istore_3
//   4: aload_0`

What is the best way to go about this? This is a bit out of my knowledge zone with refactoring and interpreting bytecode so I will need tips on how to go about this.

    Trying to figure out how to write a game client by looking at the decompiled source to one is going to be like trying to write a novel in Russian by staring at an untranslated copy of *War and Peace*. That is, it's not going to be effective. –  Jul 24 '14 at 03:52
  • find someone at linkedin that has access to the source code and pay him some bribe :-) just kidding – Leo Jul 24 '14 at 03:57

    If this Java game client happens to be Minecraft, you might be interested in the [Minecraft Coder Pack](http://mcp.ocean-labs.de/page.php?4). Much of the reverse-engineering work has been done already by modders. – Wyzard Jul 24 '14 at 04:05

    There is no easy way to go about doing this. Obfuscation is good at making it hard work to reverse engineer large applications. – Stephen C Jul 24 '14 at 04:10

    Why not instead learn how to write a game from scratch? There are lots of good books on the subject available... – keshlam Jul 24 '14 at 04:41
