setCollideWorldBounds not working

Phaser 3
1

Hi, i’m practicing my coding skill in Javascript and Phaser3. For this i try to do a space shooter. I would like an enemy ship not to leave the screen (update section. it’s in the condition " if (this.score > 50) ". I try to use the fonction setCollideWorldBounds. My program keeps telling me that setCollideWorldBounds is not a function and i don’t understand why.

What is strange is that the function setCollideWorldBounds works with my player.

Someone can help me please ?

(sorry for my bad english)

setCollideWorldBounds works on a body, not an entire group.
