Colliding with only one object at a time

Heyo!

So, this may have been answered, but I cant find it...

Say I have a group of objects lined up together, tight side-by-side. If I happen to collide between them, it will hit 2 at once. How do I get it to collide with just one and ignore the one right next to it? Can I create some kind of calculation that it picks the object that has more of the player's collider touching that one and will ignore the one that has less?

thanks!
