I had an idea for a mob trap the other day, which would use occasional water streams to push mobs off edges.
Here's some pictures:
It's 21x21 if you include walls, 19x19 if you don't.
The floors are 3 blocks tall; 2 for the spawning space and 1 for the floor. This allows you to have more floors than some of the traditional mob traps which require 4 blocks, where the water streams are down a block.
You could set this up to a long clock with a short monostable circuit or a pulse limiter to a short burst of water every so often. Alternatively, you could just have it as a manual button press, though that prevents it from being truly automatic.
Can you elaborate on this. I don't understand how it works. Does the mobs spawn in those platforms covered with water (it'll be empty I'm sure and it'll periodically flush the mobs down) or do they have another platform to spawn in and fall in the platform with water?
Seems like the pads are for spawning mobs, and periodically water will be unleashed as to push the mobs off of the platform, as to overcome the new limitations of mobs ceasing to move after you're a certain distance away. Interesting idea, I want to see how it turns out.
It would only decrease the rate if the water was flowing for a long time; it would only be a short 'burst' of water every once in a while.
And they can't jump, as I said the floors are only 3 blocks; 1 for the floor, 2 empty for spawning.
Eventually I'll build a full version, but it would require me to find a flat map with the top covered in a few blocks of water, so to prevent mobs from spawning outside of the trap.
A 'burst' of water wouldn't probably be enough to fully push them off the ledge. Even if they do get close they have a chance to move further away from the edge.
I haven't checked if they changed the spawn rate for 1.0.0 but a mob has a chance to spawn every 1/20 of a second or 20 mobs every second. Let's say you leave the spawning pads available for 3 seconds and open the water for 1 second a total of 4 seconds. In those 3 seconds let's say they spawn 100%, so that's 60 mobs. When you open the water, you basically prevent another 20 mobs from spawning. That's 33.3% reduced in spawning rates if you leave the pads empty for a full 4 seconds.
Not to mention that there's a cap of 70 mobs and every time they're not getting killed will waste space for another mob from spawning.
That's the most resource efficient one I've found and you may only need 2 or 3 levels for it to be as effective as a water-based trap (if not more effective)

Thoughts?

Essentially I'm going for something relatively simple to build, yet effective.
Are there any mob traps/towers that are still very effective, though with low resource requirements?
