How to add a cape to the player?

Hi!, I would like to know if there is a way to add a layer to the player, for example that when executing the command: "/cape" a cape was added to the player, and that it was created, and not necessarily of the Minecon, there is a way to do it?

 

You can use

PHP:

/** @var Player $player */
/** @var string $capeData */
$skin = $player->getSkin();
$player->setSkin(new Skin($skin->getSkinId(), $skin->getSkinData(), $capeData, $skin->getGeometryName(), $skin->getGeometryData()));


 

Thanks!, then I must define the string $capeData, or no?

 

Yes.

 

I need some help with the capes too. Could anyone give me a random working cape png?

thanks but it's too late
I used the method of patar and saved the cape in a file
