So if I had a pipe that starts from a chest that has dirt and cobble, and ends with a golden pipe between 2 barrels, 1 with dirt and 1 with cobble in em, it'd be 50% chance to hit the right barrel and rest of the time throw the item out of the pipe?You'd want to use clay pipes not gold pipes since they will try to input into the barrel's inventorys and if that fails move it along the pipe, while gold pipes will pop the item out of the pipe if it fails to insert and isn't guaranteed to try to put the right items into the barrel either.
