How to change the top of head of a player

Hey, my question is so difficult and easy (difficult to explain and so easy when you understand what i say)
I think all have the reply.
How to change the top of head of player.
I mean where there are write the name of the player and his life
Do you understand what i mean

Sorry for my bad englisgh

 

Do you mean the nametag of players?

 

i want to change that

where there are writted the name of player i don't know the name of that xD

 

You can use this to get the current nametag of a player:

PHP:

 //Assuming $player is an instance of Player:
  $player->getNameTag(); 

You can set the nametag of a Player(or most Entities) with this:

PHP:

 $player->setNameTag("Blah Blah"); 

If you want to make a player's nametag blue, you could do this:

PHP:

 $name = $player->getNameTag();
  $player->setNameTag(TextFormat::AQUA . $name); 

PureChat allows you to set nametags and chat formats for players, so you may want to check it out.

 

It's called "nametag"
