I found a slime chunk right inside my straight mine so I dug out a 16x16x3 chunk at level 19 and coordinates 71 19 -120. I have lit up the room light levels are above 10 everywhere and there are no other mobs spawning inside.

I have been waiting for about an hour afk with the game active at around 32 blocks away (coordinates are 90 11 -125) in order to get some slimes to spawn but still not even one.

  • Confirmed slime chunk with - http://chunkbase.com/apps/slime-finder#-1729309068124591226

  • The height level is below 40

  • Several nights have passed

  • Player position is around 32 blocks away from the center of the slime chunk (coordinates of center 7 19 7)

  • Playing on 1.12.1 without any mods
  • There isn't a huge stack of monsters around the slime chunk (there is a ravine right above it but its lit up)
  • I searched for questions like this but they were mostly either related to a different problem that I have already solved or from 2+ years ago.

What could be causing this issue?

  • What do you mean with "7 19 7"? If it's coordinates, it's far away. If it's chunk section numbers, you're above maximum build height. May 7, 2018 at 11:04
  • I don't know if 3 blocks height is enough for slimes. Have you confirmed that that works somewhere else? May 7, 2018 at 11:06
  • What's the current moon phase? Slime spawning rates depend on that. May 7, 2018 at 11:07
  • The moon phase has cycled a few times from full to new. 7 19 7 is the chunk coordinates this means the center of the chunk. They are only provided to show what i mean by center of chunk. The coordinates provided above are the global coordinates at which I stay to see if slimes will spawn. How can I check if 3 blocks high is enough for slimes ? May 7, 2018 at 11:17
  • A 3 block gap is tall enough for slimes to spawn. My slime farms always have a 3 block gap between platforms. Can you upload the map so we can look at specifics? I am currently recreating your world to try to reproduce the problem.

The coordinates you give are only about 21 blocks apart. Assuming that you have given the center of your farm (71,19,-120) and the location you are standing (90,11,-1225) you may not be far enough away.
