Techman88 | 2x2 multi-floor mob elevator to turn a mob drop farm into an XP farm Minecraft 1.13 @techman8817 | Uploaded 5 years ago | Updated 15 hours ago
1.13 bubble columns are an easy way to elevate mobs, to drop on a collection system, so you could AFK at y=192 and have a mob farm from 64 to 90 or so. But there's another thing, you can also have a switch so you can optionally use it for XP.

This will probably be seen as trivial in the future, but I want to publish the video anyway. Grian and Mumbojumbo and Loxy Bee have made videos on this kind of system, but they are for individual players, not mobs.

I also made a 3x2 version.

Easy way to make big holes to bedrock for slime farm etc (1.13.2 and maybe Spigot)

$Quartz Quarry / variable timer TNT duper flying machine (tested Minecraft 1.13.2) A machine to clear large areas of netherrack and leave the quartz exposed to be mined by the player, in such a way to be mined easily. Explodes about 63 blocks in the y direction with the time reverse version. Excavates a parabolic shape using TNT launched with variable timings, a bit like a tunnel bore. Uses a variable analog timer. Made in 1.13.2 using optifine. Works in 1.14.2 as well, but since netherrack drops 100% of items in that version, the item entity lag can be very significant (getting over 1000 entities in 1.14.2 vs ~300 in 1.13.2). 1.12 works with some modifications, see below for details. Downloads: Time reverse version, shown at end, better for lava removal: https://mega.nz/#!hwRgCYiZ!PXVLTWjH8MHNOddvkVbKaozQ2j_6uspMxu8uf7YSL8Q First version: https://mega.nz/#!JtJCgAoJ!_BYD2rS9W6ks4aukr4cNE7R1DDC61QYl34lo4x-D3Ng Swiss cheese simple version: https://mega.nz/#!ZsQ02SKA!s0_pOH5PdFV1Bw490TYEn02gh_48MGD Z_aZ842ZQg 1.12 version. NOTE: this isnt working right on carpet mod, at least version 19_05_02, but is working in single player. Occasionally the TNT wont launch or the TNT will dupe randomly(in that carpet version): https://mega.nz/#!x8wijSKI!IAempmvpoSH-EyNorzmwIka59qXKqNyEpZgfrN6kJLc More technical notes: TNT duper gave a 100% consistent y velocity, so a quick launch was not an issue. Y position 1 tick after dupe was always 0.1600000038743 blocks above initial position. Lands on trapdoor 12 gameticks after launch, so 68 game ticks of TNT fuse to work with after landing on trapdoor. Analog timer uses 14 or 15 different delays, multiplied by 4 gameticks, so 0..60 gameticks is roughly the range. Analog timer could be improved but I got tired of working on it. Got something started at least, uses an adder instead of subtractor. https://imgur.com/a/7bbnPE4 Might be possible to integrate a tunnel bore in front, and a variable timing flying machine. But I dont think this is worth the effort, especially since flying machines dont seem to get the granularity required to make a nice parabolic shape. Command to remove TNT before exploding: /execute as @e[type=tnt,nbt={Fuse:1s}] run kill @s$

$Gold Crafting system for Zombie Pigman Farm, with tutorial Helps craft gold nuggets to gold ingots, with a rate limiter, and designed to work in the nether. A lot easier than breaking chests to craft. Done by a request. The 3-high version shown will help craft a stack of gold ingots every 1.37 seconds (84 droppers, 5 items per second). This is probably fast enough. You would pre-sort the items and put only gold nuggets into this. World DL https://mega.nz/#!RhYlWQZb!aRt1yZyd7lWwzwAsAzK2KOw rLBdV-mpwyBMsvYo4k Autohotkey script. This uses 1928x1080 resolution with default GUI scale, and only works with crafting table with crafting book open. If you use different settings you would need to change the cursor position for the destination items. It works by shift clicking the crafting book recipe then shift clicking the destination items, then moving the cursor back to the original position to easily re-craft. I have to lift up ctrl and alt between crafting each one. Id rather people just use tweakaroo though, because it doesnt depend on cursor position. ;crafting ^!d:: ; Hotkey: ctrl-alt-D if(WinActive(Minecraft 1.13.2)) { MouseGetPos x, y ; back up original mouse position SetMouseDelay, 200, Play SetDefaultMouseSpeed, 0 ; Mouse movements much quicker. Minecraft seems to be fine with this. Send +{Click} ; Shift click Send +{Click, 1449, 377} ; MouseMove %x%, %y% ; move mouse back to original position } Return$
