Check if group is out of bounds

[yougotashovel]

I'm trying to check if a whole group is outside of the visible bounds, so i can process it for cleaning up memory.

 

I've got my world bounds set to this:

var w = window.innerWidth, h = window.innerHeight;game.world.setBounds(0, 0, w, h);

I've tried a few things, but i guess what i'm looking for is something like "group.events.onOutOfBounds()" I realise this doesn't exist, but is there anything that would do the job?

 

Is it possible to check if a group is out of bounds, or do i have to check everything in the group individually?

 

Thanks
