Minecraft Load Custom Mod: Error.setTextureName(Ljava/lang/String;)

[Xour21]

Hey Guys hoping to get some help with this error I have, I've created my own custom mod (called Teuton Materials for reference) I have no problem when I run the mod in InteliJ (where I built it) but when I build it using Project Structure -> Artifacts and then put into my MC mods folder and launch I get the following error.

I can't find anything about this anywhere else and all the other similar bugs I found remain unanswered, can someone point me to a forum where this has been solved or try and help with this error.

setTextureName

is the deobfuscated (MCP) name of the method, which is only used in the development environment. In the normal client, it has an obfuscated (SRG) name instead.

 

You need to build your mod using the

build

Gradle task (either from the command line or IDEA's Gradle window), this compiles and reobfuscates the mod so it uses SRG names instead of MCP names. The built mod will be in the build/libs folder of your project.

[Xour21]

Ah that makes sense, got it working now, i'm going to go and kick myself in the head for not working that out, thanks for the help.

obfuscated (SRG) name instead.

 

Just to clarify, SRG and Obfuscated are not the same.

Obfuscated: af()

SRG: func_173982_a()

MCP: doSomething()

 

The obfuscated ("notch") names are what you'd find if you examined the vanilla jar manually.  The SRG names are run-time translations that Forge performs (Forge runs a class transformer on every vanilla class at priority 1000, most coremods run afterwards, but they can run first if they so desire).  MCP ("Minecraft Coder Pack") names are the ones you see in the development environment, if they are available (otherwise you'll see the SRG names).  SRG is intended as a "version agnostic" naming scheme so that mods do not depend on a specific version of Forge to run.

[Xour21]

OK that makes sense. Now say I wanted to transfer Obfuscated files from a friend's mod back into a version that is readable by inteliJ, how would I go about that?

[Draco18s]

"Slowly and painfully"

There might be a tool out there that will do it automatically, but you can do a find-replace-all in files and manually translate SRG names to MCP by looking them up in the mappings.

 

Those are stored at:

~\.gradle\caches\minecraft\net\minecraftforge\forge\1.7.10-10.13.2.1291\unpacked\conf

Where ~ is your user directory.  In that folder will be two csv files: fields.csv and methods.csv

[Choonster]

To get the source code from a built mod, you'll have to use BON or BON2 to deobfuscate the mod and then use a Java decompiler to decompile it into source code. I list some decompilers and explain how to use BON in this thread.

 

Keep in mind that most closed source licenses don't allow you to use the code in your own mod.

Cheers for the help guy's, been really good!
