hey does this work with / can this be updated to 1.7.3?
I was wondering this as well. I used this tool last night to verify that the boundaries of my slime farms were correct. Since the update, the tool doesn't work (even after deleting the Meta-Inf folder and re-installing) and my farms are no longer spawning slimes to boot.
I have been trying to find slimes for a while now so I could make sticky pistons and I got redirected here from the minecraft wiki. I used the online tool and found out there was an area in my strip mine that would spawn slimes, so I lit up the whole place, marked up the boundaries, and sat and waited. I had to keep placing torches in spots I had missed until no more mobs spawned though. So I waited for an hour and no slimes spawned. I went back and double checked my coordinates, but everything was correct.
I don't like to add mods, but this one is pretty tiny and unobtrusive so I figured what the hey, it's to double check my work. I have 1.7.3 and it seems to work fine, albeit there is this glitch(?) I guess where it makes monster sounds but doesn't show any monsters. This freaked me out at first running around because of "invisible" monsters. A spider managed to spawn in yet another place I missed and scared the crap out of me though once I figured the noises were just noises.
So with mod installed, I checked a third time and sure enough my work was spot on. Only problem is, no slimes will spawn :sad.gif: I am at the bottom of the map one layer above bedrock, the ceiling is 6 blocks up, I am 99% confident that there are enough torches nearby to prevent other mobs from spawning, and I have been waiting 24+ blocks away from the spawn area. What am I missing?
On a side note, it seems since 1.7 came out no neutral mobs have spawned for me either :sad.gif:
UPDATE: After waiting TWO hours, finally had a medium slime spawn lol. There must be some caves nearby or something that I don't know about where other mobs are spawning.
I cannot use it. What type of Java do I need to have? (I have the level.dat file but no matter what it still won't show the picture.

PLEASE RESPOND, i got the mod and it works but it does not display the seed number or if slimes can spawn there it shows everything else though, im on MP and on the newest version,please help i really want sticky pistons, thanks

This is a great program!
Do you know a seed that has many slime chunks next to each other? Would be cool.
Trial and error, mostly. Every seed has areas where two or more slime chunks could be found within the same 4x4 chunk grid. It's just a matter of finding the 'golden' seeds which have:
--an enriched area with 2, 3, or more slime chunks within 4 chunks of each other, close to spawn
--This enriched area is situated under dry land, or close to it, so you can build a proper base to support your slime ventures
If you already have a goodly settlement built on a map, and just want slime chunks to appear in your area, and you do not care if the edges of your explored area have chunk border issues, you can always use HexEdit or NBTEdit to 'change' your map's seed in the level.dat manually. (always save a backup of your level.dat file before editing - this is essential to not corrupt your world beyond recovery)
Use the web-based slimefinder app to screen your base's coordinates and general area. Enter a bunch of seeds, pick the one which has the most green slime chunks in the given area under your base. Enter that in your level.dat and reload the world.
Note your grass colour, biomes, and weather patterns will also change. Buildings, trees, terrain contours, etc. will remain the same in established chunks.
Or you could use the existing seed and the online app to pick an auspicious place to start a new settlement.

There's always a problem loading the stupid page.
Other than that, I support the idea for posting seeds with slime-spawning chunks directly below the spawn. I'll make a topic on that in fact. to anyone who posts in that. to anyone who is a
I used the tool and found an area in my mine that had 2 chunks corner to corner to each other.
I hollowed out about 30x30 space around each chunk at 11.6 and at 6.6 to 10.6. The slimes dont seem to spawn in the rooms built at 11.6 but spawn in the bottom room at 6.6 but when they spawn after about 30 minutes, they just keep doing the bugged animation like they are falling through the roof over and over again until i go up and punch them.
Any reason why this is happening and why they are not spawning at 11.6? Every video i watch they have tons of slimes spawning back to back, in my farm its 1 maybe every 15-20 minutes
Minecraft apparently sometimes does something funky and the seed changes.
For example, my mate is running a white-listed server; after the 1.6 update we noticed that our weather changed but didn't think much of it until our previous snow areas started melting.
I found out because I got the seed information from him and tried running it through the online tool. No slimes, despite supposedly being in the right place. Since I remembered where I'd seen a slime before, I tried the mod version and that's when we found out that the seed had changed.
He went in and edited the seed back to what it was supposed to be, which fixed our weather having gone wonky (since the biomes were all different thanks to the seed change) and slimes started showing up where they were supposed to as well.
If you're using the tool and slimes aren't showing up where they're "supposed to", I'd suggest also making sure that the seed you think you're using (assuming you used a custom seed to generate your world) actually does match the seed you're playing in. It won't apply to everyone but it was a problem in our case.
1) What is the spawning time for slime? Do they share it with other hostile mobs?
2) If there are friendly/hostile mobs in chunks surrounding the one slimes spawn, do I have to go out and kill them all in order to allow more slimes to spawn in my farm? (SMP here)
3) Do slimes spawn on floor 15, providing that I leave 2 spaces between the floor and the ceiling? I couldn't do a 3-floor farm because of nearby lava deposit that extend all the way down to bedrock (even worse is the fact that one side of the farm is adjacent to that damn pool)
4) How far can I actually stay away from the farm and still allow them to spawn? Can you give the number both horizontally and vertically? Wiki says that the minimum distance is 24, but they start to despawn if noone's within 32 range blocks, while being more than 128 blocks away causes them to despawn immediately. Does it mean that if I want them to spawn whenever the timer kicks in, I should stay within 24-32 range away from the farm at all time?
I've reworked the old tool and made an online version accessible for everybody this time :wink.gif:
You can display quite a large area and locate clusters with that. Also, you can upload your level.dat to automatically determine your world seed for you.
Online Map Generator
As you can see, there are both large holes and clusters. This is absolutely random. Hope this explains why people are claiming they still get no slimes even though they made their room 10m bigger..
Note that the right screenshot is outdated, the tool will only display one coordinate, which is exactly the border (at whole number).
Seed!??!?
To make this work, you need to have access to your world file or its seed (as a number). If you do, just upload the level.dat using the form and the seed will be automatically parsed for you.
If you're on SMP, however, you need to use the ingame mod and log on to the server to find out the seeed your world's using.
Ingame Mod (1.7.x & 1.6.6)
This mod expands your F3 screen to show the world seed as well as whether or not slimes can spawn in your current chunk. You need to manually copy the .class file into your minecraft.jar (open with WinRAR or the like) and make sure to delete meta-inf folder if it's still in there.
If this doesn't help there are lots of tutorials out there, e.g. .
Finding the exact borders:
- with mod : look straight (!) down and watch the f3 text that says "Slimes: Yes" (or No). you need to place your cursor/camera so that it doesn't move if you rotate (it's easier than it sounds, just clarifying..). then move around and you can see the Slimes text changing as your cursor moves between the block
- without mod: do the same looking down thing and watch your X and Z coordinates while you move around. it will be at a whole number when crossing blocks. if that whole number is a multiple of 16, you're looking at a chunk border. do this for both x and z and you found a corner.
the multiples of 16 are displayed in the image of the online tool (the screenshot with 2 coordinates being displayed is outdated). make your area smaller if they don't show up.
Still no Slimes?
- without mod: double checked x,z coordinates?
- while standing on the spawning ground, your y coordinate must be 16.6 or less.
- room at least 2 high? :tongue.gif:
- one block above your ground, don't place anything except a few torches for lighting the room (you dont need it for slimes, just to prevent other mobs from spawning)
- don't play on peaceful!
- don't be closer than 24m to your room and don't go more than 128m away from it
- wait long enough (if your room is closed, you dont need to be around, just come back every once in a while, they won't despawn unless you walk far enough away (>128m)). obviously, don't pause the game
If you still don't get spawns after several hours (for a 16x16 room I'd say), check if other hostiles are spawning if you kill the light. It should take a slime approx. 10 times longer to spawn than other hostiles.
If no hostiles are spawning, your world's hostile spawning might be jammed by slimes. If you're alone / on SSP, walk 250m in any direction and go back. Hostiles should spawn again.
If none of this helps, report here.
Formula:
In case anyone is interested in the actual formula (in java):
xPosition and zPosition are chunk coordinates.
To sum it up, it generates a random number (0-9) that's always the same for the same chunk and world seed. if that number equals zero (10%), the chunk will spawn slimes. The constant numbers were picked randomly I guess.
You could also eliminate the Random stuff by looking up Java's Random algorithm.
I used the tool and found an area in my mine that had 2 chunks corner to corner to each other. I hollowed out about 30x30 space around each chunk at 11.6 and at 6.6 to 10.6. The slimes dont seem to spawn in the rooms built at 11.6 but spawn in the bottom room at 6.6 but when they spawn after about 30 minutes, they just keep doing the bugged animation like they are falling through the roof over and over again until i go up and punch them.Any reason why this is happening and why they are not spawning at 11.6? Every video i watch they have tons of slimes spawning back to back, in my farm its 1 maybe every 15-20 minutes
about the spawn rate:
it heavily depends on your world. if you build one 16x16 room in an otherwise natural world. I'd say you get maybe 1 slime every 15mins. But if you're alone in your world, lit up all caves as well as the surface (for night), and also flooded slime-friendly caves, you'll get insane numbers. probably one per sec or so, depending on how fast you can kill them.
about the animation:
i think it's a client side (smp only) bug. did you use any non-opaque blocks, like stairs, halfsteps, glass? did you check if there's space above your room, where slimes could spawn and get stuck?
maybe they can also get stuck in opaque blocks, if only parts of your ceiling are 2 high, or they spawn close to the wall.

1) there's no shared "spawning time" whatsoever. the game tries to spawn mobs every game tick (0.1s). if the difficulty is right and a certain limit hasn't been reached (slimes share limit etc with other hostiles), it goes through every chunk around every logged in player (128-144m in each direction) in a random order, picks a random spot and mob for every chunk and then tries to spawn a group of up to 4 mobs of that type around the spot.
so usually, you'll have a ton of the other hostile types spawning, because they aren't limited in y level, chunks and they don't have a (additional) 90% bailout like slimes do.
2) killing them won't really help as theyd just respawn. you have to light up the caves or flood them, shroom them whatever :smile.gif: but for smp this won't help as much since every logged in player would have to do this in their area.
3) they spawn on ground level 14 and below. your f3 coordinate must be 16.6 or below when standing on that ground.
4) You're right about the 24m, but wrong about the 32m thing. Slimes aren't affected by that (unlike other hostiles, maybe even every other mob ingame). So you need to be 24m-128m away. It's euclidian distance (meaning you have a 24m sphere around you, in which no mobs can spawn), so you can either go 24m in on direction, 17m diagonally etc.
I wouldn't rely on the exact numbers though because of rounding.

Odd, worked for me. maybe your problem was caused by other mods/texturepacks after updating?
Anyways, now that mcp is out, I "updated" the mod. Now shows 1.7.3 in F3 screen. Hope this fixes your problem too.

looks like you didn't install the mod at all. the f3 stuff you see comes with the original minecraft.
You can now select Random Seed to find seeds with clusters near 0,0 .
Also, you can now enter the text seed.
Awesome, I was getting a lot of questions about that. You rock.
