Weird function names


Recommended Posts

I'm new to forge modding (but decent at Java) and am following this tutorial to learn the basics (ie. adding blocks/items/gui). 

For some reason, many of the methods he uses have completely different (and odd) names with my 1.16.3 setup. For instance, where he wrote: 

  public void read(BlockState state, CompoundNBT tag) {
  counter = tag.getInt("counter");
  super.read(state, tag);

Through deduction and guessing based on inputs/returns of suggested functions (thx Intellij) I wrote:

public void func_230337_a_(BlockState p_230337_1_, CompoundNBT tag) {
    CompoundNBT invTag = tag.getCompound("inv");
    handler.ifPresent(h -> ((INBTSerializable<CompoundNBT>)h).deserializeNBT(invTag));
    super.func_230337_a_(p_230337_1_, tag);


It worked that time, but the further I go the harder it gets to guess all the names. Is it a version issue (1.14-1.16)? Or if it is a deliberate change Forge made is there a table somewhere to look up the equivalent names? Thanks in advance.

Of course, right after I post this I find that these are obfuscated names of course, and that this site can serve as a key. Feeling like, well, a little bit of a potato rn. I do wonder how he de-obfuscated his names in Intellij though, that'd make it much more convenient.

Oh well, I'll leave this up in case anyone needs it I guess, or if I'm making another blunder. Live and learn, I guess.

Those function names are called SRG names. They're the semi-reliable automated decompilation names (instead of a.a() you get Block.func_12345_c()). It is then up to the community to figure out what that function does and supply a human-readable name.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
