Weird function names

[NotAPotato]

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: 

@Override
	public void read(BlockState state, CompoundNBT tag) {
	itemHandler.deserializeNBT(tag.getCompound("inv"));
	energyStorage.deserializeNBT(tag.getCompound("energy"));
	counter = tag.getInt("counter");
	super.read(state, tag);
	}

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

@Override
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.

You should set the mappings in your build.gradle:

mappings channel: 'snapshot', version: '20201028-1.16.3'

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.
