If you only want them a certain distance from each other, but don’t want anything else affected (i.e. you don’t want their distance from walls or the Character to change) you can add a Sphere Component to the Enemy class, then set it to ignore everything but the Object Type to which the sphere component belongs (you can even create a new Object Type called EnemyDistanceSphere or something). That way, they hit each other’s spheres and don’t get closer to each other than that.
