How do I make interact 3 same objects together

So let's say you have an item "box" which is a sprite.

You have 3 "box" in your layout.

Those "box" are overlapping each other, and I would like to make them interacting to each other this way :

If a box is overlapping another box on the left, it goes 1 pixel on the right

If a box is overlapping another box on the right, it goes 1 pixel on the left

Currently, I have this :

"box" is overlapping "box" at offset -1, 0 : Set X to Self.X+1

"box" is overlapping "box" at offset 1, 0 : Set X to Self.X-1

Which is working fine for 2 item, but not 3 or more.

For each doesn't work either.

Any advice ?

For this I like to use a family with box in it. I'd name the family "otherbox".

for each box

--- box overlaps otherbox at offset (-1,0) : box set x to self.x+1

--- box overlaps otherbox at offset (1,0) : box set x to self.x-1

Ah ! working very well

Thank you so much
