Problem A: Mob spawner is too high and mobs stop walking. Solution A: Add water flushing capability to push mobs into canals. Create a 30 second hopper timer to flush mobs before they despawn. (done) Problem B: The hopper timer will open the dispenser and pour the water, but does not recover the water into the bucket. Solution B: ??? Does anyone know how I can create another circuit to tell the dispensers to recover the water right away? This circuit should be shorter than the 30 second hopper timer. The longer the water flows, the less time mobs can spawn. I have searched and searched for tutorials on this issue and cannot find any that specifically address it. Thanks for any help! I am a redstone beginner, but am eager to learn.
Thank you @bighatscoutguy for the tip you gave me today. This is me in front of my too-tall mob spawner. I was always more than 32 blocks away so mobs would not walk and fall into the water canals. I made a hopper clock to open water dispensers and release water onto the spawning platforms. But the dispensers would not retract the water for the duration of the hopper clock cycle. (96 items = about 1 minute, 20 seconds) And that meant that no mobs could spawn in that time. So, @bighatscoutguy showed me a way to make a horseshoe of repeaters that delays a signal. This gave me the ability to activate the dispensers a second time, so they would retract the water 6 seconds after it started to flow. Unfortunately, the hopper signal was still keeping the dispensers activated and they would not recover the water until the next hopper cycle. So I found a mechanism called a moved-block pulse limiter. When I placed the pulse limiter between the hopper clock and the water dispensers, it made the turn-on signal very short. When the piston activates, it cuts off the redstone signal. And then the horseshoe delayed signal could turn off the dispensers 6 seconds later. So, now I have a flushing mob spawner. It gives about 1 minute and 13 seconds to spawn mobs, and then it flushes them into the water canals. I could add more time to spawn mobs by adding more items to the hopper clock. So thanks again @bighatscoutguy! I hope this works as intended.
