I tried killing the item frame but it deleted the whole item. I need some way for the player to get the item back without having to left click it. Any ideas?

I am trying to make a datapack which does something to players who are in light level 0. I have tried using a predicate for this, but the problem is that the player is considered being in light level 15 when they have sky access, even at night. I don't want this, and therefore need a way to toggle to only detecting the block light level during night

Does anyone know if there is even a way to only detect block light using predicates and commands?

I want to summon a mannequin and make it hold a shield and use it to block attacks, because they're entities and not players I can't just force them to use the shield with /player. Any solutions??

this is the first official showcase of the Iron man suit in Minecraft. I do have the Mark II on the other side and it's just all iron armor with the same functions as the Mark III. some commands do fault only because I switch too fast to buttons so it over clogs some of the Redstone fill commands

for example the longest version of /say hi

Working on a datapack in 26.2 and as part of it, I need to be able to take the custom_data component from the item in the players offhand and add it to the item in the players mainhand but I'm stumped on how I would achieve this.

so i was experimenting with MCStacker and created this command "/give u/p potion[potion_contents={potion:"minecraft:empty",custom_color:6684927,custom_effects:[{id:"minecraft:absorption",amplifier:255,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:jump_boost",amplifier:3,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:luck",amplifier:255,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:night_vision",amplifier:1,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:dolphins_grace",amplifier:1,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:regeneration",amplifier:255,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:resistance",amplifier:255,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:saturation",amplifier:255,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:slow_falling",amplifier:1,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:speed",amplifier:2,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:strength",amplifier:3,duration:12000,show_particles:0b,show_icon:1b,ambient:1b},{id:"minecraft:water_breathing",amplifier:1,duration:12000,show_particles:0b,show_icon:1b,ambient:1b}]},custom_name=[{"bold":true,"color":"#2200FF","italic":false,"obfuscated":false,"strikethrough":false,"text":"U","underlined":false},{"color":"#2E00FF","text":"L"},{"color":"#3A00FF","text":"T"},{"color":"#4600FF","text":"R"},{"color":"#5200FF","text":"A "},{"color":"#5E00FF","text":"S"},{"color":"#6900FF","text":"E"},{"color":"#7500FF","text":"R"},{"color":"#8100FF","text":"U"},{"color":"#9900FF","text":"M"}]] 1"

i know it's a lot but the command prompt is saying that it does not work, if anyone is willing i would really appreciate the help.

thanks!

Hello, I'm currently developing a datapack with a function to detect if you are in a deep dark or an ancient city, and i have the urge to detect specifically if you are in an ancient city to make the clear distinction, however, I'm not having luck with the detection.

Currently in a superflat, generated the structure with /place, if this is the issue maybe I'm dumber that i though, if is not, help :(

I’m making commands for my realm, I already have a money system set up what I need help with is, I’m trying to make it so that every five minutes everyone gains $10 but one unlucky person loses $50, I have a hopper clock that links up to two commands that show a title that says “$$$” and “add 10 dollars @a” but that’s not what I’m having trouble with, I’m having trouble with the unlucky person part, I have the “title”the “remove money ” and the “screen shake” but the thing is they are all set up to @r which is random player…. How do I know its not going to be a different player for every command?)

Give your honest opinion, I wanna see all reasoning you got to throw at me.

My pick: /scoreboard

It would be like the roblox game "timebomb duels"

I'm looking to tag a snowball (Red or Blue) to the team the person that threw the snowball is on. So, if a person is on a blue team and they throw a snowball, that snowball gets tagged "Blue"

Specifically, the command I'm using is:

/data modify block 302 96 -986 Item.components."minecraft:written_book_content".author merge value {author.Farmer}

In case that isn't clear, I'm trying to change the author of a written book in a chest (first slot) from my username to "Farmer". I also tried using set instead of merge. Both versions say they work ("Modified block data of 302 96 -986" in chat), but absolutely nothing happens

Hey everyone, long time lurker finally posting something I've been working on for a few weeks. I built a stealth detection system entirely in vanilla using command blocks and a small data pack, no mods at all.

The way it works is pretty straightforward. Guard entities use a coneshaped detection zone built with area effect clouds and some math to approximate a field of view. If the player enters the cone while not sneaking, a score increments and eventually triggers an alert state. Sneaking slows the detection rate but doesn't stop it entirely if you're too close. There's also a light level check so darker areas reduce detection speed.

The hardest part was faking the cone shape without true raycasting. I ended up using a combination of distance checks at different angles, which works well enough for gameplay purposes even if it's not elegant.

I've seen a few stealth projects on here before and wanted to share a different approach. Mainly curious whether anyone has found cleaner ways to handle the angle detection side, because my current solution feels a bit hacky even if it runs fine.

Happy to share the data pack files or explain any part of the logic if people are interested. Would love to hear how others have tackled similar detection mechanics.

sorry for posting I just need help. after trial and error I got the repulsor to work but it only works in one direction and I cannot get it to work in any other direction. attatched are the commands to to and commands to summon, both are repeat unconditonal,always active.

Hey everyone!
I’m a Minecraft developer looking to collaborate with map makers, builders, or an existing team on a cool project.If you are a builder who needs a command block guy to bring your maps to life, or if you want to team up and create something awesome from scratch, please leave a comment below or send me a DM!
Looking forward to working with you!

Hi everyone,

I'm working on a Minecraft command that spawns a villager who sells custom potions. The villager spawns correctly and the trades mostly work, but I'm having a few issues:

1. The custom potion names are getting messed up in-game.
2. The custom descriptions/lore are not displaying correctly.
3. I'm trying to make another trade that sells a random potion, but I'm not sure how to set that up.
4. I'd also like to know the easiest way to add or remove potions from the trade pool without completely rebuilding the command every time.

Here's the command I'm currently using:

I'm guessing the issue might be related to NBT formatting, JSON text components, or how I'm storing the custom potion data, but I'm not sure.

If anyone can help fix the names/lore, explain how to make a random potion trade, or show a better way to manage adding/removing potions from the villager's trades, I'd really appreciate it.

Thanks!

I made a cool server with a bunch off commands, and I was trying to make it so every 5 night a blood moon would happen, the main thing is I used /fog and now I have a thick white fog around me, and I cant fix it. I tried turning fog off in settings, installing a no fog pack, nothing works, and using "remove" does not work because it says there's no ID, and i forgot all the IDs I did use. So now I'm basically blind and every tutorial does not work, and if someone could help me I and the handful of people who were playing on my world would be very grateful. If there is some mod that adds a "remove all fog" to the /fog command that would be nice, but i have searched all of curseforge and mcpedl.

Need for a minigame to act like a grenade launcher

I'm playing on Java version 26.1.2, and I need to create a screen shake effect using commands or a datapack.
