How to add End Poem ?

When you kill the ender dragon and go back to the original world, the game will show End Poem.
I saw this feature in some MCPE servers, how can use this feature ?

 

I think this packet has to do with it. I'm not sure whether and how you can change the text or not, but here's the packet anyway: https://github.com/pmmp/PocketMine-...e/network/mcpe/protocol/ShowCreditsPacket.php

 

I think the packet is not for this feature...
Nothing happened.

 

Could you please send the code you used for this?

 

PHP:

$packet = new ShowCreditsPacket();
$packet->playerEid = $player->getId();
$packet->status = (int)1;
$player->dataPacket($packet);


 

The packet can't display End Poem.
I saw some servers use End Poem to show their server rules.

 

I know, but ShowCreditsPacket can't display End Poem... So sad.
