How can we make player bigger, like add-ons new feature

It's fantastic. If a player has a bigger body, it must be funny. Some servers has had this new feature..But they don't want to share their plugins. It seems that using DataPacket can make it but I can't find the Packet managing this feature.

PHP:

$entity->setDataProperty(Entity::DATA_SCALE, Entity::DATA_TYPE_FLOAT, $scale);

 

Wow....Thanks. Maybe I didn't find that code in PMMP code
