I have an iron golem spawner farm. This is how it's set up:
(it extends about 30 blocks, this is just a model)
I want to redirect items to fill one column of chests at a time so that one column of chests does not get disproportionately filled, so that once the first column is full, it starts filling the second, then the third, and on and on.
How can I do this using hoppers? I've tried using water to push the items into one hopper and redirect the items from there, but it doesn't work well since the iron golems float on the water and items get burnt.
An idea I had is to make the hopper I circled in the screenshot below first check if the hopper north of it is full. If it is, then it starts filling up the hopper to the right. I'm not sure how to achieve this, though.
