I'm struggling to make my spider trap. I've looked at the linked guide, and studied the pictures, but I just cannot work out how to make the water to flow to collect all the string that is dropped.
I don't think I understand enough about how water flows to get this bit right :sad.gif: There seem to be some strange rules applied to water. For example, if you build a setup then add water, as opposed to building a setup with the water already flowing I seem to get different results!
Yeah water can be tricky... you could always message the guy that wrote that if you were really having problems. He said he might make a more detailed tutorial if there was interest.

the only reason i can see that this works is if you do wait there all night. If you don't then I don't see the monsters drowning because they will bob in the water. I have not tried this myself, but with surface ones for pig drowning they almost always bob out. The only reason they drown in yours is because you wait there and they are trying to attack you instead of swim out.
Also I'm curious if there is a creeper spawn block in dungeons?
Yes, you have to stay in the collection block so they will stay under water. no, there aren't creeper spawners.

I told you earlier that there are not creeper spawn blocks, but wanted to add that you can build a mob harvester in a dark cave and harvest creepers that way. i found a cave system that had a large room with several branches, and seemed to have a lot of monsters in it. I built a mob harvester in it, removed all the lights, and left my guy to idle in it all night. after about 10 hours i had a little more than 5 stacks (275) gunpowder, arrows, and feathers.
I've working on a spider trap and I've perfected it so that it gives string every time. It is done with slight modifications to the original zombie one.
Water blocks are placed in the same place except for the addition of 2 more. In the row behind glass, dig out two spaces on the right and two spaces on the left and plack spring blocks at the backs of them. Follow the video tutorial but with those slight changes. Dig 2 down in the fifth row and three down for the sixth and seventh and add a glass block.
Hey, I'm the guy that created the Spider Trap linked above. I've updated with a video showing the whole construction which can be found . Make sure you read the video description, it has two things of note I forgot to mention in the video and a link to the still image gallery of the original trap.
My original design was very similar to emck96's, however some of the string was being lost in stagnant water so I added the second flow in the back to resolve this.
The teal block represents a the only stagnant water block in the configuration. This row of blocks has no flow pulling items out of it and down to the collection point. The water blocks above and next to this row of blocks are all straight down flowing water. Any block at the bottom of a vertical column of water needs an empty air block beside it to produce a sideways water flow. This sideways water flow actually pulls items from the downflow water block next to it. Replacing this empty air block with a downwards flowing water block breaks the flow and leaves a stagnant block of water than can hold items there until they despawn.
This is the reason my trap uses two water flows, one for each of the waterfall columns, ensuring no stagnant water and no item despawns. It is definitely more work to build, but it maximizes efficiency.
^^ he's right. i tried building one like emck previously, but not all drops get swept out due to the water mechanics. jaqyl's design is the only one ive seen that will sweep all spider drops out.
As for the pig trap, you can use the same method as the rest for it to work; They're the same as the rest,
But they might be harder to drown.
So try to have a little water vortex in the pig trap.
Is switching to peaceful the only way to suppress spawns while you work? I tried encasing a spawner in cobblestone (3x3) but it didn't stop spawns outside it. It seemed from the videos like you were doing something with the torches, though. How far away from a spawner will monsters spawn, assuming there's space?
When I was working on my spider trap I just placed a cobble block on top of the spawner and put a torch on all four sides of the cobble. I think this still let one spider out every once in a long while but I'm not sure you can avoid that entirely. Keep in mind the original tap was built on a SMP server so the mob spawning rules may be a tad different there.
I'm thinking a cobble above and below the trap with torches on all four sides would be about as good as you can do. You probably want to make sure the rest of the room it is in is fully lit as well.

there can be some weird spawns where a monster can spawn more than 1 block away from the spawner... i had one side blocked off with cobblestone once, and couldn't figure out why a monster would spawn behind that wall. that's why i recommend to enclose yourself if you plan to afk for a while in the trap. i left my guy in it all night once, and at some point a monster spawned outside the trap (or something... maybe it came in from another path) and killed me... so i didn't get any drops, and lost everything i had accumulated up to that point.
anyway... usually if you throw down a torch on each of the 4 faces, it will keep them from spawning. when you dig out the floor, just leave the stone attached to those faces. then, right at the end you can destroy the blocks and torches at the same time. you have to be quick though, because monsters will spawn almost immediately. i would always build a path out to a side wall, and i would destroy 2 or 3 at once, run back, kill monsters, and when i got a clear moment i would go back in to destroy the last block/torch.
Here is my spider capable trap. I have 2 block wide trenches running down the side of my house since im still experimenting with traps. I'm abusing water column vacuum which is somewhat difficult to describe.
I wanted to have the simplest possible trap in a small space that could still do spiders. I ran into this problem as well originally with not being able to drown pigs. I wanted to do it without cactus or lava since I dont have either.
Drowning a spider.
My first implementation was this learners trap, two blocks wide in profile view here.

This was ok for everything minus spiders and pigs. Needless to say I got killed by a spider going to check my loot one time. Oops.
Then I tried this, with a hole poked into the side for loot. The 3x2 water section drowns spiders/pigs and the loot still falls down ok.

Solving the 2x2 water column, normally water going off a ledge down into a 2x2 pit only fills two squares with water and wont drown anything that well.

I temporarily put 2 springs up on the ledge pouring down into the 2x2 cavity filling the empty space, and when they were removed it was... filled! Not sure why this works, but it manages to suck everything down as well too.
Here is the ledge and the trenches that go together. There is a 2x2x1 dropoff before going to the 2x2x3 drowning area. Sorry it was difficult to get a better angle to show it all at once.
Loot collection. 1 extra spring is placed to direct the water down the 1 block exit. Seems to work well so far! I imagine this could be modified for a dungeon in some way. I was trying to go for compactness.
This thing kills everything except chickens (but I don't see any reason to build it on the surface, works alot better underground) and transports all the loot to a safe location where you can idle without getting killed.
It can also easily be modified to work with a monster-spawner.
If you are on a vanilla server, you have to earn everything you have using the current game mechanics, no items created out of thin air by mods/admins. That makes traps pretty much the only source of string on SMP.
String is the only legit way to get cloth blocks on SMP right now as you can't punch cloth off sheep. Also, people want to make bows and fishing poles even though they don't have a true "use" right now on SMP

just wanted to thank the OP for this this. Just started a new map and I found a skeleton spawner pretty close my spawn and just under where I made my first shelter. I've been running the trap for the past hour or so, and I already have 3.5 stacks of arrows. I think it's time to go creeper hunting. :biggrin.gif:

Here is why this design loses drops . . .

Don't hate on me cause I'm K.E.W.L

I will get a pic soon, maybe.
