Move entity

Hey. I want to boost a pig away like a snowball if a player interacts with the item id 1. I already tried something. But this only teleports the entity to a location and did not work like what I expected.

PHP:

public function interact(PlayerInteractEvent $event) {
if($event->getItem()->getId() == 1) {
//Don't really know how to create the entity :/
/*
Code to create it?!
*/
$entity->addMovement($x, $y, $z);
}
}

 

No idea?

 

You can try Living::knockBack()

 

If you are using addEntityPacket to spawn the entity, you can easily move her using the MoveEntityPacket

 

Can u give me an example?
