I noticed in the documentation for Matter Physics there is an overlap function.  
[https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Matter.MatterPhysics.html#overlap\_\_anchor](https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Matter.MatterPhysics.html#overlap__anchor)

however when I try:  
this.matter.overlap(shot, this.shieldBack)

I get `this.matter.overlap` is not a function. (within my scene object)

Make sure you are running phaser 3.22 or later. It sounds as though you might run an older version.

Tried 3.21, 3.22 and 3.23

also `Phaser.Physics.Matter.MatterPhysics.overlap()`  
Still no luck

There is definitely `this.matter.overlap()` in Phaser v3.23.0.

Ok, I tried 3.23 again and it’s working.  
I thought I flushed my browser cache, but I guess maybe it held on to 3.21.
