I'm not sure how to explain what I'm having a problem with if you couldn't tell by the title, so I will just give an example. The following is in the Block class.

public void fallOn(Level p_152426_, BlockState p_152427_, BlockPos p_152428_, Entity p_152429_, float p_152430_)
{
  p_152429_.causeFallDamage(p_152430_, 1.0F, DamageSource.FALL);
}

All of the parameters are named starting with the letter 'p' then a sequence of numbers. I heard that there is a way to fix this, but I don't know how. Do you know?

That's because Forge works with decompiled code and since Minecraft obfuscates thier source code. The decompiled code does not have any information about the parameter names.

If you want parameter names you could use Parchment

Thank you so much! That was exactly what I was looking for. This is going to make my life so much easier.
