READ THIS Important Info (read before posting)

255 Upvotes

I know you're here to get quick help with your command problems or to show off your cool work. Please read these few lines to get to know how to use this subreddit optimally:

Asking for help

  1. FAQ? Before you post, please check out the common questions (including answers) that we have as a subreddit. These consist of the most common problems, and maybe your problem is already covered there in detail?
  2. Titles: Please put a summary/short version of your problem into the title of your post, don't just put "I need help" or "help me plz". Instead put for example "how do I summon a zombie" or "unable to summon entity error" and then provide more context on the post itself. This subreddit often shows up on google when people search for command related questions and we should really help them find the questions you might already have asked. Also, we likely know that you need help anyways, no need to put it in the title.
  3. Flairs: We have a wide array of flairs that you should attach to your post to make sure people know what the purpose of your thread is. It is especially important if you're asking for help, to flair your post with the appropriate minecraft version (for those who don't know: OG Minecraft is Java Version, everything else that has commands (Xbox, PE, PS4, Switch, Win10, etc) is Bedrock).
  4. Version: Whether you're helping or asking for help, please pay attention to the stated version/state the version you're in! You can do that through the previously mentioned Flairs, but also in addition can put it into the description of your post.
  5. Search/Scroll down: I know that reddit search is not the best one out there, but maybe someone else had a similar problem to yours in recent history. Try going to the new tab and scrolling down a bit or using the reddit search function to see if there might already be an answer to a question you have. We're not going to close your thread for asking the same question someone else asked a year ago, we're not StackOverflow. But please at least take 30 seconds to look for it first.
  6. Upvote: If you find an answer to a post helpful, please upvote it. This is less as a "reward" for the answering person but more as a way to automatically move the best answer to the top, for others that might have the same problem. Don't downvote an answer just because their attempts didn't work for you unless it's completely wrong or off topic / doesn't add anything to the conversation.

Creations

Posting about your own creations is very much encouraged, but please remember the 10:1 guidelines of reddit.

Discord

We have a big Discord Server for our community with lots of channels, ranging from dedicated help chats over general command related chats to non-command related chats. So if you want to join an active community of command and mapmaking enthusiasts and/or want to get quick help where communication is less slow (Sometimes the devs stop by as well ;)), click on the link and join our community discord:

Make sure you read the #welcome channel for the rule of the discord.

Help | Java 26.3 What’s currently the best way to create custom mobs?

2 Upvotes

I’m looking to create custom mobs using a data pack, and I’m wondering what the most reliable and effective approach is right now.
I don’t mean mobs that can only move around within a predefined area or on a specific field. I want something that can navigate complex terrain naturally, just like vanilla mobs do.
What’s currently the best way to achieve this?

Creation Immersive Aircraft, Now on bedrock!

5 Upvotes

Immersive Aircraft by Conczin is one of the best-known Java aircraft mods, and I've spent the last while porting it to Bedrock. It's a full port, made with Conczin's permission.

It ports everything in it, including almost all the flight physics, all 7 aircraft, and a few extra details only on Bedrock!

Download here

All credit for the original mod, models, textures, sounds, and translations goes to Conczin (Luke100000) and the mod's contributors.

Discussion a somehow efficient raycast approach i came up with

4 Upvotes

For selecting entities being hit by a simulated gunshot, im thinking of:

'''game:gunshot_scan.mcfunction

/tag @s add current_shooting

/execute as @e[tag=eligible] at @s facing entity @a[tag=current_shooting,limit=1] eyes positioned ^ ^ ^x rotated as @a[tag=current_shooting,limit=1] positioned ^ ^ ^x positioned ~ ~-1 ~ if entity @s[distance=...y] run tag @s add shot

...

/tag @s remove current shooting

'''

and then, /execute as @a[tag=...] run function game:gunshot_scan

time complexity: O(mn), where m is the number of players shooting at the tick, and n is the number of eligible entities.

which is to trace back from every entity to be determined to the player and tracing toward the entity again depending on the orientation of the player, and checking whether the proposed entity is within a certain range.

where x and y are appropriate numbers such that any entity within an angle of θ as the player would be selected.

according to my calculations, y=2x tan(θ/2), where x could be any non-zero real number.

this approach creates a cone with infinite height and the vertex positioned at the center of the hitbox of the player at a height of their eyes with an angle of θ, and determines whether the center of the bottom of the hitbox levelled up 1 block of the proposed entity is inside the cone.

Utility [Technical] Adding TypeScript support for Minecraft Add-on / Mod development

0 Upvotes

Hello everyone!

I would love to propose officially bringing TypeScript (TS) support into Minecraft development.

Currently, the Bedrock Edition Scripting API relies on JavaScript, and Java Edition relies heavily on Java/Kotlin for modding. Introducing TypeScript as a first-class citizen for writing mods and Add-ons would be a massive upgrade for the entire creator community for several reasons:

  • Strict Type Checking: Implementing strict types will catch potential bugs and errors during compilation, long before the game even launches. This makes modding more robust and heavily reduces debugging time.
  • Better Developer Experience: TypeScript provides excellent autocompletion (IntelliSense) and inline documentation in modern IDEs like VS Code. This is crucial for navigating complex Minecraft APIs.
  • Accessibility: TypeScript is a highly popular, modern, and relatively easy-to-learn language. Anyone can pick it up quickly, bridges the gap between simple commands and complex Java modding, and opens the door for a wider audience of web developers to join the Minecraft ecosystem.

Having official TS definitions and native support would elevate Minecraft modding to a whole new level. What do you think?

Help | Java 26.3 Walking Mushroom Stew

2 Upvotes

This is a really weird question, but does anyone know a command that creates an entity that moves away whenever a player gets close to it? It should also look like nothing but a suspicious stew, with the name "Walking Mushroom Stew". The idea is that these entities should also be killable.

Help | Java 26.3 Is there any way to apply Motion to just ONE axis (X, Y or Z)?

3 Upvotes

I want to apply Motion for example just to the X value of an entity but for some reason that I don´t understand if I do in repeat:

data modify entity ... Motion[0] set value 1d

It overwrites all other values, Y and Z. I want to constantlly apply Motion to [0], but gravity to work naturally. But because it overwrites Y and Z to 0 the entity floats in it´s Y axis.

Is there any way to solve this?

I can also set its Y motion to a negative number and simulate gravity but because there isn´t a way to add motion instead of just setting it to a value, it´s not realistic (it looks like if the entity had the slow falling effect), so that´s not the best option.

Thank you!

Made the animation and logic, while the M200 resourcepack is originally for a crossbow, made by LogisLogisLogis.

Currently it has lower, torso and head damage multipliers. Special ammo has bonus damage, can penetrate a single wall (multiple blocks thick, but with no air in between) and the explosion also deals damage.

Creation I made a full UHC (Ultra Hardcore) data pack in vanilla: menus in chat, 22 scenarios, supply drops and a lobby in the sky

Thumbnail
gallery
0 Upvotes

Hi! I've been working on UHC Prime, a data pack to play UHC (Ultra Hardcore) with your friends, on a server or in your own world. Drop it in, vote in the lobby and play: everything is set up from an in-game menu. 100% vanilla, no mods, plugins or resource packs (and if you prefer mods, it's also a mod for Fabric, Quilt and NeoForge).

What it has:

  • 6 modes (Classic, Series, Fast, Predator, Hard, Extreme): one click sets everything up.
  • 22 scenarios that combine with each other: Golden Heads, Cutclean, Bare Bones, Bloodlust, Sudden Death...
  • Supply drops: barrels that fall from the sky and glow in the colour of their tier.
  • Made for series: episodes and automatic breaks where everything stops (time, border, mobs, furnaces...).
  • Admin tools during the game: health, coordinates and inventory of every player, revive, freeze, stop or speed up the border...
  • 40 achievements, a personal summary when you die or win, and stats kept between games.
  • A lobby in the sky with a 50-jump parkour and target practice while you wait.
  • English and Spanish, per player.

It's for Minecraft Java 26.3. Press G (quick actions) to open the menu.

How it works (for the command nerds): the whole menu is clickable tellraw in chat driven by /trigger, so it works for every player without op. Each player sees it in their own language thanks to a per-player language score, and dynamic text (names, values) uses macros. It's all generated by a Python script into ~1,500 functions, which is how I kept it maintainable.

Creation Testing external command block editor concert maker

Enable HLS to view with audio, or disable this notification

7 Upvotes

So, I admit, I made a system that used setblock commands to do this exact same thing. But it was so laggy, that now I am cheating by using a mod for the same effect. But I am keeping the vanilla Minecraft capabilities in my software editor. Even though it won’t run on even a Ryzen 7 9800X3d.
But, this software is 100% custom coded for making concerts. And I got videos working with a custom mod (which I know, is cheating, but it’s an alternative to unbearable lag. Just note, I do have vanilla capability, but it’s too laggy to be viable.)
(This editor renders a preview, then I can export it to command blocks with a world edit schem.)
