I’ve watched and read a lot of Minecraft loader/unloader video tutorials. Everything I’ve found is A to B with loading happening on one end and unloading on the other. I’m wondering if there is a way to have a single main line but with a loop at each end and both loading and unloading happening at each end. I’m trying to figure out a way to automate sending and receiving on the same line. For example, I’d like resource A to be loaded at X and unloaded at Y while the minecart is still at Y pick up resource B and unloade it back at X and then repeat the circuit continually regardless of there being resources in the chests at each end but if there are resources to be transported the minecart would stop and collect them and then transport them to the opposite end.
I could but I'd have to have a complete loop so that after the unloader it goes to the loader and then goes back on a different line. I'm trying to have the carts go back on the same line and that's what I'm having trouble figuring out is how to get them back on the main line.
