I have an automatic anvil replacement system using redstone. An observer detects when the existing anvil breaks, and then the ceiling opens up allowing one anvil to fall down.
The replacement anvils fall from the ceiling which is about 20 blocks high. From that height, the anvils almost always end up chipped after they fall.
I want to add some redstone near the bottom that will stop an anvil from taking damage after it falls 20 blocks.
I have tried a dispenser that shoots out water as the anvil gets close, but it seems that water doesn't break an anvil's fall.
I also had pistons that pop out of the wall one by one, but it takes way too much time for an anvil to reach the floor.
Find a way to stop an anvil from taking damage when it hits the floor using a redstone contraption.
