Remove from group

[K1m]

How to remove items (sprites) from group, if I know only their coordinates. I did this:

my_group.forEach(function(item) {    if (item.x == 10 && item.y == 10) {        my_group.remove(item);    }});

and have error Cannot read property 'x' of undefined

When you loop copy 'item' into a local array. After the forEach loop run through the array and call 'remove' on each one.
