Prevent bouncing balls from overlapping

Hey Danny, this is something that have been bugging me for years.. now I’m using bouncing balls as units for a game I’m making but the problem is, when deploying too many units at the time, even with event “if unit overlapping unit, make them bounce”, and using loop, there still some units that get cluttered on top of each other… is there a more cleaver way to force them to not overlap? Thanks
