So, skeletons (and zombies? maybe?) go for shaded areas when the sun rises. Do they do this with enough predictability to make a trap out of an overhang?
I was thinking of making an overhang with a trapdoor(or a few trap doors) with a major fall, or water at the bottom to drown and collect.. The main question is if they would go to it enough for it to really matter?
I'm still relatively new to the game, (been playing a few months now) so I'm just now starting to play with mob traps, not really able to get to a real spawner right now though :-/
That's an interesting idea, the problem is most mobs stop moving after a little while and gradually despawn if they are more than 32 blocks away from a player, so not only would you only get one catch per night, it would only be from from a small area around you.
So you'd probably be better off using yourself as bait to lure them into a trap.
(or running around luring them into multiple traps.)
Or else using dispensers with water buckets to periodically flush them into the traps.
