Heyho 
i have a short question…
I try to modify the playername with the
"event.getTargetEntity().offer(Keys.DISPLAY_NAME, Text.of(TextColors.DARK_AQUA,“Testname”));"
The Transactionresult shows that the Transaction was successfull but the name did not changed…

Is there any way to change the name above the player beside scoreboards?
Thanks in advance 
Greetings Kyraja
