Spiders, they suck...


I built this Mob Farm accordingly to the tutorial, and it's pretty efficient ! There is still one problem though: Spiders! Since they can now climb wall, it's possible that they block the funnel ! Emptying 1 more ceiling block seems to correct this. --Yamitatsu 16:37, 17 January 2011 (UTC)


 * Thanks a lot for the feedback! I didn't really notice the lack of string production, and I certainly didn't connect spiders' new climbing ability to any issues with the farm. I added your image and solution to the main page. MrMatthew 19:16, 17 January 2011 (UTC)


 * You're welcome^^
 * Well, in fact, it didn't just stopped the string production, as you can see on the screenshot, many mobs were stuck behind the spider, so the whole process was stopped :/
 * I let it activated the whole afternoon with the small correction, and so far, no more interruption :) Filled a large chest with all the loots:) I'm thinking about making another 50x50 spawn room above the first one, this could maybe give a lil boost to the production^^


 * Anyway, thanks for the tutorial, well explained :) Though I had to make some schemes on OOo Calc to be sure not to do any mistake since English isn't my mother-tongue, lol^^

 * I've heard that a block of cacti in the right place can stop spiders clogging the trap, and with the new dispensers needing bows to make, yes, we do need that much string. --Nahere 01:00, 18 January 2011 (UTC)
 * Even by updating the funnel to properly funnel and kill spiders, the fact is that many won't even end up in the kill area, since they can just climb their way out of the canals to begin with. If you're looking to kill spiders, this is probably not the best way to go about it, so a spider-specific farm might be in order. Hmm, new challenge for me! MrMatthew 18:49, 18 January 2011 (UTC)
 * Yeah, not that much spiders, the fact is they can jump easily above the 2 blocks canals, maybe with 4 blocks it would prevent them from stay safe outta water^^. Though, sometimes when i go check through the glass along the funnel, i see 4 or 5 spiders in it, i guess that's because i come closer and they try to get me^^.

 * I was told that spiders cannot climb sandstone, so I'm planning to shut my farm down and put a line of sandstone around the inside of the canals. I'll let everyone know how that goes when I complete it. (EDIT: After checking the sandstone page, it does appear that spiders CAN climb sandstone. Hmm, back to the drawing board I guess...)

 * Well, it's kinda rare, but spider can still block the funnel, they seem to climb the wall on the side, i'll try to make it 4 blocks large and add a row of cacti on each side...

 * I'm pretty sure they can't climb soul sand (the small amount of invisible gap makes them fall, I think) --Thevdude 15:52, 26 January 2011 (UTC)

Notification System
At the end, it might help to make some wooden pressure planks that lead up to the surface with redstone and light up a torch or make a sound with the note blocks so that you know you've got items awaiting you... Eldonman101
 * On mine, I do have a redstone wire and torch system that spirals around my mining shaft (I was actually thinking about doing a tutorial on it) that let's me know when there are items. However, the rate that this machine kicks out items, it's almost always going to be on. Once you assure the machine is working, the need for a redstone alert system is a little unnecessary, but I urge you to make this farm your own! MrMatthew 18:56, 20 January 2011 (UTC)

Ladders vs Signs
Is there any benefit to using ladders vs signs for retaining the lava? I created a mob farm according to these plans and used signs... It seems to work fine. My reasoning was that the mobs might climb up the ladders a bit and then they would have a higher chance of their loot dropping into the lava when they died. Thoughts? --Samuraifalcon 20:45, 24 January 2011 (UTC)
 * I didn't think mobs could climb ladders. That would be the only difference, I just use ladders because I always have ladders on me when I'm mining. MrMatthew 17:10, 25 January 2011 (UTC)
 * I believe mobs have at least the mechanics to climb ladders, as recorded in the article on Ladders and the corresponding talk page.  Mobs may not have the A.I. to "climb" one or more ladders as a part of their pathfinding, but the mechanic of climbing exists for them if the mob moves next to the ladder, which would be likely here. Also, you make a valid point about already having ladders. Anyways, a minor difference but some may be interested :) --Samuraifalcon 19:45, 25 January 2011 (UTC)
