Math Function Library - Custom Commands in Minecraft 1.12 emeraldfyr3 2017-05-14 | Exponents, logarithms, roots, random numbers, and more! 1.12 brings with it the new /function command, which allows Minecraft command scripting without command blocks. To make use of this wonderful addition, I wrote a library of math functions for scoreboard values that you can import and run in any world.**After you import the functions, be sure to run math:init to create the scoreboard objectives!**Math Functions:http://www.mediafire.com/file/ofk14vd1brodar7/math.zipWorld Download:http://www.mediafire.com/file/i1t3vtuakol2l2b/Math_Functions.zipIncluded Math Functions:divide_round: division that rounds the result to the nearest integerfactorial: factorial of the given numberlog: logarithm of the given base for the given numberpower: the given number raised to the given powerrandom: a random number in a specified range, up to 31 bitsroot: the nth root of the given numberround: round the given number to the nearest multiple of another number

Datapack Challenge: Detect Minecraft 1.13.2 with Functions emeraldfyr3 2020-12-26 | Challenge for Minecraft command experts: Can you detect 1.13.2 with a datapack? Read below for more details!GOAL:Create a function or datapack that sets a scoreboard value differently when loaded in 1.13.1 vs 1.13.2. For example, running a function in 1.13.1 will set the score of player "patch" in objective "mcversion" to 1 in 1.13.1, and 2 in 1.13.2.GUIDELINES:The solution will most likely require observing some in-game behavior that changed between 1.13.1 and 1.13.2. This may require running certain commands, summoning entities, and/or placing blocks.A perfect solution would only require commands, without using any entities or blocks. The next-best solution would use entities, but not require placing blocks. In addition, determining the version instantly is better than having some delay.See my Minecraft Version Detector datapack on GitHub for examples:github.com/emeraldfyr3/mc-versionMinecraft Version Detector Datapack Video:youtube.com/watch?v=zUJ4QgKk4zsHow to Block YouTube Ads:github.com/emeraldfyr3/block-yt-ads/blob/master/README.md
Minecraft Version Detector Datapack Minecraft Java 1.13-1.17 emeraldfyr3 2020-12-23 | Get the running version of Minecraft as scoreboard values. This datapack finds the version by testing for Minecraft features and bug fixes that were added over time.DOWNLOAD:github.com/emeraldfyr3/mc-version/archive/master.zipHOW TO USE:Put the datapack in your world's datapacks folder, and on world load the minecraft version will be stored in scoreboard values in the objective mcversion. The first number is "major", the second is "minor", and the third is "patch". For exampe, 1.16.4 would be major=1, minor=16, patch=4.All release versions from 1.13 to 1.17 are detected except 1.13.2, 1.15.1, and 1.16.1.GitHub Repo:github.com/emeraldfyr3/mc-versionHow to Block YouTube Ads:github.com/emeraldfyr3/block-yt-ads/blob/master/README.md

Command+Q Fix for Mac: Drop Stacks of Items emeraldfyr3 2020-08-29 | Anyone else switch from Windows and accidentally quit the game trying to drop a stack of items? Here's how to make Cmd+Q drop a stack of items just like Ctrl+Q in Windows:1. Open System Preferences2. Go to Keyboard ⟩ Shortcuts ⟩ App Shortcuts3. Click "+" to add a new shortcut4. Put "Quit java" as the Menu Title (NOTE: If your game is modded, make sure that the text matches the option to quit the game from your computer's menu bar -- it might not be "Quit java".)5. Click into the Keyboard Shortcut field and press Control and Q at the same time. Make sure to press Control, not Command.6. Click Add to save the shortcutThis works by switching the shortcut to quit the game to Control+Q instead of Command+Q. This also switches it for any other Java executables named "java". Now, pressing Command+Q in Minecraft will drop a stack without quitting the game.

0-Tick Loops with Chain Commands (Minecraft 17w16) No longer works! See description. emeraldfyr3 2017-04-22 | UPDATE: The next snapshot, 17w17a, added the UpdateLastExecution tag to command blocks. Now to enable loops, instead of cloning the blocks, just set that tag to 0 on all the blocks in the loop.The changes to Chain Command Blocks in 17w16 enable modification of the chain while it's executing, allowing for conditional branches within the same tick.

Silent, Compact Dual Edge Detector (Minecraft 1.9) emeraldfyr3 2016-03-06 | Use levers as buttons! This is a dual edge detector, which means it pulses every time the state of the input redstone is changed. This design is only 3x2x1, and it uses some strange redstone behavior to make a 0-tick pulse whenever the input state is changed. To increase the pulse length and/or negate the output, you can hook up the output a dropper pointing into a hopper and take a comparator output from either.

Improved Two-Way Bedrock Door [1.8.3] emeraldfyr3 2015-03-08 | Go up AND down through the ceiling of the Nether in 1.8.3. This design improved the concept I showed in my previous video so that it works anywhere in the Nether, so long as there is at least one bedrock at y=127 that has no extra bedrock below it.Previous video:youtube.com/watch?v=LiulUQyE3t8Sethbling's Slime Block Drawbridge:youtube.com/watch?v=R3Y9fse9hwA
Two-Way Bedrock Door + Tutorial [1.8.3] (Updated Version In Description) emeraldfyr3 2015-02-26 | UPDATED VERSION HERE: youtube.com/watch?v=Dy8E0JwzsQIA two-way door through the roof of the Nether, extra useful now that the bedrock-breaking bugs have been patched. It's basically a horse in a minecart on top of a triple-piston extender. A double- piston extender also works, but the player suffocates in the ceiling until they get off the horse, so I think the triple is better.If anyone can think of any way to improve this design (such as a replacement for the horse that can't suffocate to death) please do let me know!
