Solved How do I spawn a mob with code

How to spawn mob in the player position
-- With CustomName
-- Without showing the mob (size 0)

 

What's the point of spawning in a chicken if it's gonna be invisible..???

You first have to register the chicken entity
then do

PHP:

$entity->setDataFlag(Entity::DATA_FLAGS, Entity::DATA_FLAG_INVISIBLE, true);

to make the entity invisible.

Then do

PHP:

$entity->setNameTagAlwaysVisible(True);
$entity->setNameTag("CUSTOM NAME");


to make the entity have a custom name

 

PHP:

$entity = new Zombie($this->getLevel(), Zombie::createBaseNBT($position));
$entity->spawnToAll();
