I need help adapting new nbt

I read this thread https://forums.pmmp.io/threads/adapting-old-code-using-compoundtags-since-api-3-0-0-alpha12.5975/ that adapt old code to new code but i need help.

In his example he shows how to replace the old child tag compound to new.
Like this
unset($nbt->SomeTag);
should be replaced with
$nbt->removeTag("SomeTag");

But what if this one has more object or function?
unset($nbt->SomeTag); //
unset($nbt->SomeTag->hasMoreObject); //idk what shall i call this. Is this calling object to another object? Im a nub lol.
Shall i remove it with the last object like this?
$nbt->removeTag("hasMoreObject");

I need help lol

 

If you unset($nbt->sometag) then $nbt->sometag will deleted fully. You just need to delete the root of tag.
