CommandForge
You don’t learn to code by dragging blocks forever. Here you type a plain command —
set, move, repeat, define — and a real interpreter runs it
on your device and builds the block scene. Ten short labs, each graded against a goal. A wrong run just shows
you exactly what’s off. It’s the friendly step between drag-blocks and real code.
Loading the labs…
Meet the cast — the characters who teach this
-
Tacker The set command - a precise mole who places exactly ONE block at exactly ONE named spot (no more, no less); naming the exact place is how a build stays true -
Nimble Relative coordinates (~ and ^) - a fast squirrel who counts from where she stands, never from the far corner of the world; 'one step from here' beats a giant number every time -
Seeker Selectors (@kind[within=N]) - a long-eared dog who acts on EVERY thing that matches a description, all at once, instead of chasing them one by one -
Whendle The conditional (when...do) - a watchful meerkat who names the moment first and only lets the action fire WHEN the condition is true -
Rondo The loop (repeat N) - a steady woodpecker who does the same small move exactly as many times as you count, and trusts the count to carry him -
Namer define - a wise crow who bundles a whole sequence of steps into ONE new named move, so nobody ever has to list them all again
