MiniBench New to Minecraft commands? MiniBench Labs teach one idea at a time — and you learn by building it yourself, in a real pack. Each Lab sets a goal, walks you through the steps, and checks your work with a friendly nudge when you're close. Here's how a Lab works, and the full Track A lineup.

5 hands-on Labs, in order — each builds on the last. This is exactly what you'll find in the app; open them in MiniBench to actually do them.
Write a greeting with tellraw, then run it yourself with /function greet.
Open greet.mcfunction and find the tellraw line that shows a welcome message.
tellraw sends formatted text to a player. Bedrock uses the "rawtext" shape — an array of text parts.
Make sure the function has no errors before you run it.
Use tick.json so your function runs every tick, and gate it with a tag so it doesn't spam.
Open tick.json and confirm it lists the function that should run every tick.
tick.json's "values" array names the functions Minecraft runs on every game tick (20 times per second).
In tick.mcfunction, find the tag that stops the greeting from repeating.
The selector tag=!greeted matches only players who haven't been greeted yet; tag @s add greeted marks them afterwards.
Make sure tick.mcfunction has no errors.
Point commands at exactly who you mean with selectors: @p, @a, @e, @s.
Add a command that targets every player with @a.
@a = all players, @p = nearest, @s = the executor, @e = any entity. @a is great for broadcasts.
Add an @e selector that filters by type, e.g. @e[type=armor_stand].
Selector arguments narrow the match: type= by entity, r= by radius, c= by count.
Make sure the function has no errors.
Place and build with coordinates: absolute, relative ~, and local ^.
Use setblock with relative coordinates (~) to place a block near you.
~ means "relative to the executor": ~ ~1 ~ is one block up. Plain numbers are absolute world coordinates.
Use fill to place a region of blocks between two corners.
fill takes two coordinate triples — the opposite corners of the box to fill.
Summon an entity at a coordinate.
summon <entity> <x> <y> <z> spawns it; ~ ~ ~ spawns at the executor's feet.
Make sure the function has no errors.
Chain context with /execute as … at … run to run a command from each target's position.
Use /execute as @a at @s run … to run a command from every player's position.
as changes who "@s" is; at moves the execution origin there, so ~ ~ ~ follows them.
Open the 3D preview to confirm your build appears in the scene.
The preview follows your commands and shows the result — a quick visual check before you export.
Make sure the function has no errors.
Labs teach you commands as you write them. When you're ready to write your own, here's the editor in full.
