[1.6.4] How to modify existing mods?

[Hardy]

Hello.

I want to start public server with FTB modpack, and for that i want to modify some mods to add additional checks for griefing protection.

I have MCP and jd-gui installed.

The problem is: in decompiled mods, all minecraft functions called like func_digits (func_123456), and in MCP there is human-readable names.

As far as i can understand, i need custom SRG to decompile minecraft (obf2pkgmcp.srg) from there: https://github.com/agaricusb/MinecraftRemapping

The problem is that latest version there is 1.6.2, and i need 1.6.4.

 

How to do that?

 

And of course i don't want to redistribute those modified mods, i just want to set up grief-free server.

 

Thanks in advance.

best thing to try first is possibly see if they have a source avaliable or ask for one to be provided, if you tell them the circumstances they may be willing to help you in that respect or possibly set up an api for you to work with, but be careful cause modding somebodies mod without their permission and using it on a public server may make some people grumpy even if it is for a good cause

 

that aside all else fails and you still want to decompile and and work with it anyway im not quite sure how to deobfuscate it

best thing to do with that is you cant find a program to help or people telling you how is to place print in statements and see how and when the code runns possibly, if you see any methods that look familiar try comparing them to vanilla classes they might be the deobfuscated verion of them in those classes maybe?
