Title: Mob Grinder
Post by: Thorin on May 22, 2012, 10:49:11 AM
Mob Grinder - where it is?

It takes _way_ too long to level up by just wandering around since mobs don't spawn during the day.  Although I suppose I could just go underground and not light it up enough...  Everything's better in a mine, it seems.

We don't have a lvl grinder that I know of (IE weakens mobs to kill for XP) but there is a loot grinder near the spawn city bridge where you can collect lots of mob drops.

Best place to lvl grind is here:
http://mc.tomasu.org/#/-25/64/-375/max/0/0

Bring a bow and plenty of arrows and go to town. You can snipe from the tower and you only have to worry about spiders. I've gone up at least 5 levels in one night there.

Err, what's the diff between a level grinder and a loot grinder?  Does the loot grinder kill them all the way?

I'm thinking of digging out a room, putting a raised dais in the middle, and only lighting it with redstone torches.  That oughta get all the monsters to spawn next to me, hey?  Maybe a dais is bad, maybe I need a three-block tower.

If mobs are killed by environmental damage they drop no experience orbs

If you put a hit on them after environmental damage they will drop xp

I don't know if you want to trap yourself, you could go into the nether and follow the murder brick road to the stronghold and fight all the Blazes you want lol

Yes, a basic grinder just kills the mobs due to environment damage then collects the loot in a spot... You just stand their and fill up on arrows meat etc.
An XP grinder hurts the mobs then lets you kill them usually though a small opening in one or two shots, allowing you to collect XP.

Ah yes, I suppose the loot grinder is for collecting arrows and bones (seriously, what use is there for rotten flesh what with everyone having a wheat farm?).

Here's my thought for a level grinder:

11x11x4 underground room, no torches
one side has a door in it
behind the door is a hallway one block wide, three blocks wide, full of torches (so no spawn
in the hallway is a pressure plate that opens the door
Go stand on the pressure plate, wait for mobs to spawn, battle them one or two at a time in the hallway, if you get too hurt back up off the pressure plate and they should stop coming.

Although I suppose once they're on your side of the door they're stepping on the pressure plate.

I guess another way to do it is have the hallway, have a single fence instead of the door, and then you can attack them over the fence without them overrunning you.  Hmm, although creepers will destroy that.  Maybe there needs to be water.

Damn, brain juices are flowing again!

Post by: Mr. Analog on May 22, 2012, 12:47:29 PM
Why not make it taller so some mobs take fall damage? (they can spawn in the air)

You could also build it so that there's a wall with a gap at the bottom and attack the enemies' feet or a ladder to a high vantage point made from slabs where you can snipe with arrows.

Title: Re: Mob Grinder
Post by: Thorin on May 22, 2012, 02:56:49 PM
But dogs don't need food once you've tamed them, do you?  I guess to breed them...

And I dunno know about you but I don't leave home without an entire stack of bread.  Even after 8 hours of Minecrafting, I still have some left.  Maybe I should trade you some bread, since I have two separate wheat fields now :)

They can get hurt, and will need food eventually if they are protecting you.

Correct, if you are using them for combat they lose health (indicated by their tail angle) and you can heal them with food... They can eat raw food just fine. As you pointed out it can also be used for breeding.

I did not know about them taking damage during combat and the tail angle indicating what they're at health-wise.  Good thing that even though I saw no use for the rotten flesh, I still hoarded it obsessively like everything else in the game :)

That's the one I used for the XP farm.
Title: Re: Mob Grinder
Post by: Thorin on May 31, 2012, 10:45:53 AM
So I found a skelly spawner a couple blocks underground yesterday, east of Frontier Station.  I built the water elevator / drop trap XP farm out of it.  Because it was so close to the surface, the elevator and drop stick out of the ground: http://mc.tomasu.org/#/120/64/655/max/0/0.

The easiest way to get to it is to go to Frontier Station, then on the south side of said station there is a path and a door leading to an underground passage: http://mc.tomasu.org/#/61/64/707/max/0/0.  There's a sign, so if you turn on Major POIs on the map you should see it.  The underground passage is about 120 blocks, and leads to the spawner as well as a room hollowed out for storage and a bigger room hollowed out for an enchanting table (future plans!).

Man, it's easy to get bonemeal and arrows now!  And if you're starting off in Spawn City, just get to the above-ground Pineview Station (a short walk from the underground Pineview Station, hidden behind Lucky's tower: http://mc.tomasu.org/#/-2/64/191/max/0/0), then take the C line to Southern Junction Station (http://mc.tomasu.org/#/-34/64/571/max/0/0), then the D line to Frontier Station.

Oh, and I plan to make it all much prettier :)

Wow, 28 levels worth of experience orbs takes two and a half minutes to absorb?!

So I'm a numbers guy, so here's some numbers.  You went from just under level 7 (121xp) to three bars over level 35 (2,319xp). 2,319xp - 121xp = 2,198xp.  Those three bars are probably 20xp, so I'm rounding that up to 22x.  2,198xp + 22xp = 2,220xp.  Skellies are worth 5xp each.  2,220xp / 5xp/skelly = 444 skeletons killed!  You probably averaged 500 arrows and 800 bones!

Not bad for an hour and a half idling and having to brew a potion (of healing II) before that.

Still, it showcases how hard it'll be to get all the way up to level 50.
Title: Re: Mob Grinder
Post by: Tom on May 31, 2012, 12:33:56 PM
One thing to note, I think that grinder may be causing lag occasionally. Something about it seems to cause the minecraft server to get stuck somewhere. So if you find yourself disconnected when idling at a grinder, its because the server was restarted. fyi.
Title: Re: Mob Grinder
Post by: Thorin on May 31, 2012, 01:03:22 PM
k, and mine's not under water so if I get spawned up top I won't have to panic :)  Too bad if it really is the grinder causing lag.

What ever it is, it doesn't always happen. It could just be a weird random quirk. server gets stuck using 20-80% cpu or so, and nothing but a full shutdown and startup of the minecraft server settles it.

If its on login, the server itself has to connect to minecraft.net to authenticate you, after you authenticate. It's annoying. Usually that's why it times out before the actual map loads.

The general feeling I get from other forums is that large grinders tend to cause lag, however other do not..

Some people are indicating that it is flowing fluids like lava and water that create the lag, others say it is the number of mobs spawning dieing and spawning again...

hard to say really..

On a related note I removed the source blocks from my lava tower and it is taking mindcraft DAYS for it to dissipate... not sure if this is contributing or not.

You do, I left my character logged in for several hours last night, and it was STILL going down slowly.... Didn't leave it over night, but I think I am going to need it.

Also noticed last night when going around portals that I almost completely lagged out going through one portal in particular. I plan on looking at that closer next time I am on.

I collected some and planted them near my house when I first got started, feel free to prune them (just be sure to replant). In the past I have created massive amounts of sugar cane, at one point the entire beach in front of the area with my tall buildings was all sugar cane...

Title: Re: Mob Grinder
Post by: Thorin on June 02, 2012, 01:26:29 PM
lol

It works good :)  You were in before I changed it, there's a couple of blocks of glass so you can see the skellies better and I'm replacing all the cobble with stone brick and there's a three-layer wheat farm just up a ladder now.  I tried replacing the sides of the drop trap with glass so you could see the skellies falling from outside, but then they lit on fire from the sunlight, so that didn't work.  Wasted a couple stacks of glass panes on that :(

A diamond helmet with Protection IV _and_ Respiration III is an awesome item!  Might want to only wear it when you're building in water, though, so it lasts longer.

I see you have TooManyItems installed, but what are the icons at the top left?  And why does the Diamond Helmet have "310" next to it?

Oh, and what's causing your bow to get damaged?
Title: Re: Mob Grinder
Post by: Mr. Analog on June 02, 2012, 01:34:19 PM
Yeah, it's pretty badass that's for sure! I got to build a storage locker for it (diving suit lol)

I can't wait to see the changes on the grinder :)

Icons on the top left (from left to right, only works if you are a mod in SMP):
-Creative Mode Toggle
-Downpour Toggle (rain/snow)
-Set-time: Sunrise
-Set-time: Midday
-Set-time: Evening
-Set-time: Midnight

TooManyItems makes the item code visible for every item so you can easily differentiate between similar looking things (also so you know the code if you want to use the /give command)

/give Thorin 310 64

64 diamond helmets!

My Mob Grinder had to be built on top of a huge open cavern, so yeah I've built walls to hold you in, and to look over, but if you jump up on the retaining wall, there is the potential for these ghosts to push you off.

I'll post the position soon.  I want to clean it up a bit so I don't have to really show you how to get to it.  Right now it is just a bunch of random cut tunnels I made while parting it out and together.  Really can get lost (even I did a few times) with my sudden ending or winding tunnels.
Title: Re: Mob Grinder
Post by: Melbosa on July 04, 2012, 06:06:43 PM
OK Mob Grinder is here: http://mc.tomasu.org/#/-1778/64/-152/max/0/0

Look for the Doors right next too the Portal in the Stone Brick section right there.  Follow the signs down from there and you will get there very easily.

WARNING!  The game has a clipping problem when so many of these mobs fill the final spot, so you might not want to try and just sit there and wait for massive pill up, as you may not be able to push your way through the GHOST ZOMBIES to get to the actual ones to kill.

You can get about 4 lvl every 3 mins or so, at least at the lower lvls.
Title: Re: Mob Grinder
Post by: Thorin on July 13, 2012, 11:31:32 AM
Mob Grinder Math!

Mob spawners spawn 4 mobs every 10 to 40 seconds (every 25 seconds average).

1.2.5
- top level is 50, which takes 4,625xp
- 4,625xp / 5xp/mob = 925 mobs
- at the Skelly Farm, this will take 232 spawnings (232 * 4 = 928 mobs); 232 spawnings will take 39 to 155 minutes (97 minutes average)
- at the Double-Zomb Farm, this will take 116 spawnings (116 * (4*2) = 928 mobs); 116 spawnings will take 20 to 78 minutes (49 minutes average)

1.3
- top level is 30, which takes 825xp
- 825xp / 5xp/mob = 165 mobs
- at the Skelly Farm, this will take 42 spawnings (42 * 4 = 168 mobs); 42 spawnings will take 7 to 28 minutes (18 minutes average)
- at the Double-Zomb Farm, this will take 21 spawnings (21 * (4*2) = 168 mobs); 21 spawnings will take 4 to 14 minutes (9 minutes average)

So...  If you can wait with enchanting for three more weeks, I recommend it; it'll be 5 to 6 times as fast once 1.3 comes out.
Title: Re: Mob Grinder
Post by: Thorin on September 01, 2013, 09:19:24 PM
I was exploring and I found two zombie spawners and a skeleton spawner, all close enough to each other to activate at the same time!  I spent this weekend trying to build an xp farm out of them, and finally succeeded..  My skelly xp farm takes about 15 minutes to go from level 0 to 30, this new one takes about 7 minutes.  I've put in an enchantment table, and nicknamed it the "super xp farm".

So how do you get there?  The easiest way is though the nether.  Get to the main spawn chamber and head south (I've marked the path with stone bricks).  About 90 blocks south you'll get to two sets of double doors; the ones to the left are to all my other portals, the ones to the right are to the super xp farm.  Go right and just follow the passage about twenty blocks, then it turns; keep following the passage until you get to a portal marked "Super XP Farm".  This portal will pop you right into the main chamber, and as soon as you appear the spawners will start spawning.

Careful with zombie spawners every hit on a zombie has a chance of spawning another zombie

Will they spawn if the light levels are too high?

Speaking of zombies, the skelli farm get zombies coming up from the "basement", so you'd best make sure that set of doors is closed. This potentially means the skelli farm could be made to be a bit faster, by making sure things are lit up better, and all paths around the farm are blocked off.

I've killed over 500 zombies from those spawners already and haven't had any problems with zombies spawning outside the kill zone. What I've noticed is that zombies have one to two hit points more than skeletons - I drop them 22 blocks which should leave them with one hit point and be one hit killable and the skeletons are, but the zombies take two punches before they drop.

The zombies at the skelly farm are spontaneously spawning in caves around it. They don't affect the spawn rate of the skeletons.

Anyway, this XP farm is quick. If you let it sit for ten minutes to load up on zombies and skellies, you will be level 45 by the time you finally clear them all out. And it's decked out with a lava disposal, enchanting table, and full library.

Maybe I'll build a Tele-Portal to it.

Location of the Super XP Farm should now show up on the overviewer.  Above-ground entrance (turn on signs to find it): http://mc.tomasu.org/#/-139/64/1372/-1/0/0.  Cave view (turn on signs to make it obvious): http://mc.tomasu.org/#/-220/64/1401/-1/0/2.  Portal in the nether (yes, turn on signs to find it easier): http://mc.tomasu.org/#/33/64/110/max/1/0.

Well, once the overviewer updates you'll see this stuff, anyway.

I didn't realize just how close I was to my hotel, I'd wandered all over further south and at some point must've turned north.

I might have to build a track from there to my new base, in the nether.
Title: Re: Mob Grinder
Post by: Thorin on September 10, 2013, 12:54:27 PM
Umm, follow the stone brick road already laid out in the nether, since your new base already connects to my stone brick hallways there.  No need to build extra paths.

Your new base's portal in the nether: http://mc.tomasu.org/#/220/64/-10/max/1/0
The super XP farm's portal in the nether: http://mc.tomasu.org/#/27/64/119/max/1/0
The path in between: http://mc.tomasu.org/#/126/64/40/-2/1/0

Really, it should be simple for you to get there.

The problem is the distance, not that a path doesn't exist. :P I'm lazy. get in a cart, press button, arrive a minute or two later at destination. much better for my rsi ;)

Oh, I missed the keyword "track", my mind read that as "path" or "hallway".  Well, don't mess up my beautiful hallways please :)

I suspect I'll have to build it over or under the paths. Because there are often branches on both sides.

I built a portal right in the killing chamber at the super XP farm. What I've noticed is that if I step into the nether, the number of mobs in the killing chamber is remembered. This means that I can use the portal to enter the nether, then travel back to my hotel portal and get back to my hotel, and when I come back to the super XP farm tomorrow I don't have to wait for it to load up.

It's kinda neat stepping in from the nether and having 50 or so mobs waiting for me already.

Also, I'm trying to get Silk Touch in a book so I can put it on shears and absolutely no luck yet (and I've done 25 books already, thanks Tom for them).

Hm, I've lost waiting mobs in the skelli grinder by going to the nether. I wonder if its that portal doing something strange.

I think there is a relationship between distances and unloading even in different dimensions.
Title: Re: Mob Grinder
Post by: Tom on September 12, 2013, 03:17:40 PM
It was my understanding that once you teleport out of range of a chunk (including across dimensions), the chunks you were in are unloaded, and any mobs in those chunks are deleted.

Well it could be how close the portal is.  However, I've gone from the kill room through the portal then used /home to go to my hotel, then logged off, and the same mobs were still there the next day.  So I dunno why, but I've shown up and had 50+ mobs waiting for me.  If I walk away far enough without switching dimensions, they're gone when I get back.
