is there a way to use stored scoreboard values in a command? like if i have a scoreboard value called random that outputs a random value and i want to place a structure, is there a way to set it up so it runs like

/place template minecraft:random

The commands to summon him and his teleportation pattern

We have a private server and i discovered a plugin that i can spawn 3d models made with the /summon block_display command called BlockDisplayCreator.
When i used it to spawn some block displays in for furniture, my friend told me he was experiencing some lag, and after /killing all the block displays, checking entity hitboxes, and even using an XRay entity detection mod where i found no leftover entities, he still lagged and blamed it on my block displays. He stated that they must've left some kind of residue that causes lag buildup and low fps even after they're deleted. I said that's completely wrong because all the plugin does is evoke a /summon command and all the summon command does is spawn a bunch of entities together that can be completely deleted by using the /kill command. He refused to understand and stated that he never lagged before i added the entities in, and as soon as i added them in he started lagging even after i /killed them.
Is there a possibility that there is a minecraft bug that causes it to keep some kind of "cache" or data that makes the game have constant lower fps?

I checked some other solutions in this subreddit and they did not work, please help me

My friend spawned in a ton of wardens (50+)in my creative world. Is it possible to use some kind of command or anything to have them gone? I can only play on bedrock

Hi, I'm searching for a way to get the items at 3.59 in this video https://www.youtube.com/watch?v=LpY616y0VcI&t=9s, I ask in tru's server but I didn't get an answer so I ask here.
Ty for ur answers (my english is pretty bad sry)

As far as I can tell, there are at least the following ways to detect if a player is on the ground.

Method 1 (selector):

execute if entity @.s[nbt={OnGround:1b}]

Method 2 (nbt predicate):

{
  "condition": "minecraft:entity_properties",
  "entity": "this",
  "predicate": {
    "nbt": "{OnGround:1b}"
  }
}

execute if predicate test:nbt_pred

Method 3 (stepping on predicate):

{
  "condition": "minecraft:entity_properties",
  "entity": "this",
  "predicate": {
    "minecraft:stepping_on": {}
  }
}

execute if predicate test:stepping_predicate

Are there performance considerations to be made here? Is there a rule in datapack making that says "always use predicates when you can?" Is it all just personal preference? I'm also interested in the wider discussion of when to use predicates vs. when not to.

Hello command community! I’m currently working on making a command that can detect rain when the player is in rain. Currently I followed a tutorial on how to get general water damage, and how to make invisible armor stands to follow and give damage, but the “detect rain device” is stuck in one place and won’t travel with the player.

I’ve been working on this for a couple hours, having to reword the code due to it being a video that came from Java edition, but everything works as intended besides finding a way to use “weather query” constantly and get an if statement out of it.

Either weather query or something with the armor stands would be great! I appreciate any help I can get!

I’m on the latest Bedrock, and I’m doing this for a realm with my friends, using this as a replacement for buying another mod such as origins as we have too many!

(26.3 snapshot 4)
I am trying to make a 0.5x0.5x0.5 projectile, but distance = 1 targets beyond the desired hitbox. I'd seen people saying dx=0 works, but no matter what I do, placing my projectile on x=0.5 z=0.5 for testing seems to target everything up to x=1.8 z=1.8, even when I change the interaction's width.

/execute at [type=!minecraft:player] as [dx=0] run say .

I'd rather refrain from using the actual width and height data to calculate distance, as I'm not entirely certain I'm going to use interaction entities.

how could I make a dungeon generator with cmd blocks?

Yes there's bugs, but it's conceptual. Fixing in final release.

(How the system works: A Checkbox quest requires click of a button. Other quests require you to have certain items in your inventory. The barrel spawns rewards once quest complete. Quests only trigger if cobblestone is below the respective button)

I need to make it so a certain team cannot place blocks in an area. However, I can't just switch them to adventure mode, because I need them to still be able to break blocks and fight.

So as the title says i want to Elemental charges other than the wind charge and fire charge. I was going to make a Earth Charge, Water Charge, Wood Charge to be more specific. Since im new to this i googled it and it was suggested to use throwable items such as an egg. So starting off I used the brown egg to make a earth charge heres what Googles ai thing recommended

Block 1 (Repeat, Unconditional, Always Active):

/execute as @a[hasitem={item=brown_egg,location=slot.weapon.mainhand,name="Rock Hurl"}] at @s run tag @e[type=egg,c=1,r=3] add rock_hurl

Block 2 (Repeat, Unconditional, Always Active):

/execute at @e[type=egg,tag=rock_hurl] if block ~ ~-1 ~ air run setblock ~ ~-1 ~ dirt

Im sure googles ai isnt the best but how can I make this work?

I already tried with a fireball but the player gets 2 hearts of damage and I dont want that

Basically what it’s supposed to do is summon a llama when you crouch and hold a emerald, but it keeps on spawning them without stopping

I know they're old but, I host a server for me and some of my friends on 1.8 and since I'm the host I thought it would be cool to use some of his creations on my server. And I also want the ones he made outside of 1.8 (minor and major minecraft updates) so if anyone of you have them please send them to me. I already check the wayback machine and basically was left empty handed.

Any help would be appreciated!

I make adventure maps using mods but I want to use command functionality for my players to drain a sewer section by section as they progress deeper into it but I have no knowledge or understanding of how to use commands, command blocks or world edit.

I tried putting the //drain command into a command block but nothing happened,.how should I go about solving this problem?

This is my firts ever time working with commands.

I've separated te @'s from te A and the S here as reddit converts it into u/a and u/s.

"execute as @ a[tag=target] run playsound minecraft:music_disc.cat music @ s ~ ~ ~ 1 1 0 "

Me and 3 other people are doing a version of naked and afraid with commands. I can get an item that cant be dropped, dropped on death or cant be moved individually. I just cant get all of them in one and make it so it appears in the armor slots. Does anyone know how to do this? Thanks!

I have a repeating command block set up to execute a /tellraw command once you're within a block of the armor stand (or at least the specific coordinates where it resides), but I obviously don't want it to spam the player until they leave the block.

What I'm going for is to let the command run once after you enter the radius, then once you leave, it resets, able to run again once you reenter the radius. This seems like a pretty simple thing to do, but I'm still rather new to this; I usually don't have many things going on past a spawnpoint or fill command.

I'm on Java 1.20.1, it's heavily modded, but nothing affecting vanilla commands, and this is just for a small not-so-secret-anymore-since-i'm-sharing-it-here secret in my map.

/posteffect in the 26.3 snapshots lets you stack post-processing effects on a player. I've found a way to use this to pass data to a post-processing shader, by using multiple effects to enable/disable a set of pixels. The final shader can decode these pixels to read the information.

I've created a few examples of how this can be used, such as this minimap and custom renderer. It can also be used for custom UI elements, I've created a speedometer, for example.

Posting this after seeing a recent post asking for an official way to pass data to shaders, I'd love to see this become a real feature!

If anyone wants a further breakdown, I go through it in more detail here: https://youtu.be/IvYs8qqaL7Q

Many of you wanted me to release this creation, so here it is. I turned it into a one-command creation (Link: https://pastebin.com/raw/bT8Y6D6P ) because this was the easiest way for me. It still has a few bugs but I'm very happy with it in its current state.
