Roundcraft

An open-source, kid-friendly Three.js mini game built by dads and kids. Roundcraft is a small round adventure world for learning coding together.

Run locally

python3 -m http.server 8000

Then open http://localhost:8000 in your browser.

Do not open index.html directly as a file. The game uses small JavaScript modules, so the browser needs a local server.

Project shape

• index.html: small page shell
• src/main.js: main game loop and world rules
• src/styles.css: screen and HUD styling
• src/sheep.js: sheep behavior
• src/tools.js: Pickaxe, Bow, and arrows
• src/audio.js: lava, pickaxe, bow, and dragon sounds

Controls

• W, A, S, D: move
• Mouse: look around
• Space: jump
• Q: switch between Pickaxe and Bow
• I: open or close the Backpack
• 1 to 8: use a Hotbar slot
• Hold left mouse button: mine lava crystals
• Hold left mouse button on volcano rock: dig a tunnel through the volcano
• Hold left mouse button on the wooden house: destroy it and collect wood
• With the Bow selected, left mouse shoots visible arrows at the Round Dragon
• Sheep walk on grass. Hit them with the Pickaxe or Bow to collect sheep meat.
• If fewer than two sheep are left, new sheep can appear after 30 seconds.

For families

This project is intentionally small and easy to change. The goal is not a perfect game engine. The goal is to build a first playable world together with kids and make it fun to learn by changing real code.
