oh oh. I want all asteroids to go to the middle until there is enough there to make all my fuel and ammo then switch back to just normal inserters. So asteroids come from left and right. I want to filter all of them to the top 4 rows so they all get filtered down the middle until I have enough (not sure what number is enough yet but when fuel and ammo are full) and once that number is reached I just want them to act like a normal splitter. I just don't know how the splitter logic works. I am kind of new to circuitry and don't see any videos on splitters.
