Hello!

How do you check if an object is out of the world bound using Phaser3?

I am looking for this Phaser3 equivalent code:

block.checkWorldBounds = true;  
block.events.onOutOfBounds.add(lose, this)

> collideWorldBounds is for whether there’s a collision at all and onWorldBounds is for whether you want an event fired for it. Inside-or-outside isn’t really covered. You could use Rectangle.Contains() or maybe a special overlap collider. See [Arcade.Group#defaults](https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.Group.html#defaults__anchor).
