Deobfuscating minecraft

[Craftist]

Hello everyone!

 

I'm not perfect in English, so try to understand me.

(П.с. если что, я русский)

 

What's the problem:

I wanna make mechanism like furnace (3 slots, 1 input, 1 fuel slot and 1 output), I was trying to do this by watching at Minecraft's furnace code, but...

There was functions like func_149930_e.

Could you tell me what does it mean? Maybe, this is secret Mojang language?

No.

 

I guess, in Mojang variables and functions named properly.

 

So how to deobfuscate Minecraft function and variable names?

when coding minecraft im sure that in mojang they use normal language with understandable words, but because they dont give the source code away the community has to work with it, an awsome dude made MCP which takes most of the code and translates it into something readable..

there are still stuff that are not translated yet and its being worked on as we speak im sure and more gets translated with the versions..

to my knowledge you cannot do anything to get the real meaning of these funcs other than keep following them to see what in they do in the end.....

 

about the furnace code, where is the code that is obfuscated? what version of forge/minecraft do you use?

It's in BlockFurnace class.

I'm using recommended 1.7.10 build. And the same Minecraft.

[shadowfacts]

In the

minecraft

block of the

build.gradle

file, specify the

mappings

property to be the latest MCP mappings for your version. You can find the latest MCP mappings here.

 

Edit: Stop using 1.7.10, it's ancient

It's in BlockFurnace class.

I'm using recommended 1.7.10 build. And the same Minecraft.

dont forget that you can always download the latest and look at that code but i dont know if it'll work...

between the 1.7.10 and 1.10.2 versions they did deobfuscated the furnace and that's how it looks in 1.10.2 (although again i dont think it'll work on 1.7.10)

and yes, 1.7.10 is ancient..

Oh, then, I'll use Forge 1.10.2.
