This is the Vanilla TargetBar, it displays The Name of the NPC Target and its HP Value, that i know.

 

Question: Is there a way or lets say Value that a i can give a Zombie in the "entityclasses.xml" that i can reference in the "TargetBar" so it's Text is also displayed?

 

for example when looking at the Zombie Arlene:

 

Arlene

100/100 HP
