Why cmdblock

From / to sorcery

First lesson: give yourself a diamond. Lesson forty: a wave-survival arena with classes and a leaderboard.

Same command. Two editions.

Flip your edition once — the tools, sandbox, and command library show the syntax that works on your platform.

BEDROCK
/effect @a speed 30 1
JAVA
/effect give @a speed 30 1
BEDROCK
/title @a title Welcome

# give yourself a diamond sword
/give @s diamond_sword 1

Open & free, always

Every lesson, tool, and command — free. Your progress exports any time.

What makes it different

Not a wiki. A place where things run.

Live sandbox

Watch commands run

Type any command and cmdblock executes it in a real simulated world — inventories, mobs, scoreboards, weather, and Steve and Alex reacting to what you do.

Open the sandbox
Real outcomes

Build things you'll play

Every course ends in something real — a teleporter network, a custom boss fight, a wave-survival arena with a leaderboard. You don't memorize commands. You ship a build.

Bedrock & Java

Two editions, one toolkit

Flip your edition once and the tools, sandbox, and command library adapt. /effect @s speed on Bedrock, /effect give @s speed on Java — cmdblock shows the one that works on your platform.

From the test world

When the chain just won't trigger

We've all been there. cmdblock is the answer when /execute is fighting you.

CMDBLOCK TEST WORLD
test world · replay
<Thankdapro> try /execute as @a run say test
<mossy_stone7> hmm that isnt working how do i do it
<Gravastar_> did you set the first block to repeat
<mossy_stone7> yeah still not triggering the chain
<Thankdapro> dont ask me, learn from cmdblock.org
<mossy_stone7> isnt that the one with java and bedrock together
<Thankdapro> yeah explains both so you dont get stuck like this
