Curious how to make an XP farm to grind all those levels or repair your tools?  Curious what the game mechanics are behind making an iron farm?  Trying to find those slime chunks?  Regardless of what knowledge you are looking for, we are here to try to help!  Anything that can be figured out via “in-game” knowledge is fair game on the 77th, and we want you to benefit from what we’ve learned.

All the information below pertains to Bedrock version of Minecraft.  Java is slightly different and not everything translates between the versions.  These are brief tutorials and information about each subject.  More links to information may be in each section.

• What is a chunk?
  • A chunk in the game is 16 blocks wide, 16 blocks long, and from bedrock to build limit.  The game does a number of things within these chunks.  From Limiting redstone, loading what can and can’t spawn, and what can be loaded to you.  Chunks can be quite useful when trying to make sure the entire part of a redstone machine is activated (as if you walk away only part may work and break your machine).  There is also a 1 in 10 chance of a chunk allowing slimes to spawn under lv 40.
  • Figure out what the borders of a chunk are can be done two ways:
    • If cords are enabled, take the number of the X or Z value, and divide by 16.  This will be one corner.  Then either search the opposite corner until you find another number also divisible by 16, or
• Slime chunks
  • Slime chunks are a little different from the Java version.  In Java, they are completely random and depend on knowledge of the seed.  In Bedrock, they decided to make the slime chunks the same regardless of what seed you are playing on.  That means that if you knew your cords, or were about to guess how close to 0,0 you are, then you could figure out what slime chunks are around you, regardless what world you are part of.
    • To figure out where a slime chunk is the old fashion way is to hop into a creative flat world, go to an area where you see slimes spawning, and then make note of the cords.  Then use the chunk formula to figure out your borders.  This denotes the is that slime will spawn in each world.
    • There are some sites that already have done this via the math of the game.  One simple version is at depressed-pho.github.io/slime-finder-pe.  You can also use this downloadable document with cords & a map of an area near 0,0.
  • The simplest way to make use of a slime chunk is to clear out from bedrock to LV 40, as well as a few blocks around the chunk.  Then make platforms at least 2 blocks high, going up to LV 40.  Some designs use water to push the slimes off, but the slimes will move and eventually sump off the platforms.  Also, be sure to light up (usually done with jack-o-lanterns) so other mobs don’t also spawn.  Then you can use a number of killing methods (most often water pushing into cacti) to kill and collect the slimeballs.
  • So long as you are within spawning distance (128 blocks?) the slime will spawn and be active.  Also, remember to get better rates to light up surrounding caves.
• Mob caps & Spawning

    For natural spawns, there are certain limitations.  There is a 200 mob cap for all loaded chunks, and certain distances (as shown in the image) where mobs can naturally spawn.

  • Unnatural spawns (such as Mob Spawners, iron Golumns, etc) and excluded mobs (name mobs, mobs moved between dimensions, etc) do not count toward this mob cap.
• Red Stone Logic
  • There are some basic redstone features that are useful to everyone.  This image includes some of the most basic ones.
