YOUR THING
DRAG IT.✳SNAP IT.✳MAKE IT YOURS.✳GMG. LET’S BUILD.✳BUILD SOMETHING GREAT.
A LITTLE HEAD START

Skip the blank canvas.

Start with a kit. Change everything.
That’s kind of the point.

01 / DREAM IT

A tiny tweak.
Or a big idea.

Keybinds, gear, building, conditions, variables. Give your idea a place to start.

02 / BUILD IT

Connect blocks.
Connect the dots.

Real snapping blocks, nested logic and custom actions. Test in a safe, simulated playground.

03 / PLAY IT

Hit export.
Make it real.

Copy or download a userscript. Install it in Tampermonkey with the GMG loader, or export both in one file.

✳

You’ve got an idea.
Let’s give it some blocks.

FROM IDEA TO IN-GAME

Three steps. Endless ideas.

  1. Build your project.

    Choose a kit or start blank. Drag an event into the workspace, then snap actions underneath. Put reporters inside inputs and controls around stacks.

  2. Test and save.

    The block preview uses simulated data. Mod test lab runs a matching game client and server locally with an imported game pack. Save a project file to keep an editable backup.

  3. Export to Tampermonkey.

    Install Tampermonkey from its official website. Export “One-file mod”, create a new userscript, replace its contents, and save. Or install GMG Loader once and install your paired project script. Reload a supported game page.

Use exported mods only where the game or server owner permits them. A successful simulation does not guarantee a game version is compatible. One active GMG project per game tab.
TAKE IT INTO THE GAME

Your mod, ready to go.

No hosted code updates or account required. Your exported file contains your project. GMG’s watermark appears quietly at the bottom right.
SAVED ON THIS DEVICE

Your little universe.

No cloud sync in this edition. Download project backups before clearing browser storage.
READY-MADE. FULLY EDITABLE.

The client is your canvas.

These are real connected blocks. Change a hotkey, change an action, or rebuild a behavior. Your changes are included in project saves and userscript exports.

Adding sets keeps your existing key bindings. Each movement key includes press and release scripts. F8 pauses your mod; native controls then take over.

The library exposes player controls and game actions through blocks. Turn on Advanced for the complete imported client and simulation source.
