How to make HUD display

I want to know how to make a custom HUD on my server that will pop up a certain message on the display above the inventory. It will also have to contain the xyz coords of the player, and a random text.

Please help me. I am a noob at PHP and I don't know anything about how to code player events or anything like that. I am hoping to learn from the source code but it seems I cannot find something that would do the above.

Thanks.

 

Just use hud basic code :/

 

PHP:

/** @var Player $p*/
$p->sendPopup($p->x, $p->y, $p->z . "Text");

2nd method

PHP:

$p->sendTip($p->x, $p->y, $p->z . "text");


I advice you to use Tip because popup is cancelled when player switch items in inventory

 

You'll also need a task.
