The sandbox: try it without an account

The sandbox opens the Hello World game in the online editor. Nothing to install, no account: you change the code, click ▶ Test, and the game runs in your browser with your changes.

1. Open the sandbox.
2. On the left, open src/Scene/HelloScene.php.
3. Replace 'HELLO WORLD!' with your own text, or change the speed (90 * $dt).
4. Click ▶ Test: the game starts on the right. The arrow keys move the text, Space plays a sound.

Your files are saved as you type, for this browser only, for 30 days. Start over goes back to the original game.

You can start from any game on the site: /bac-a-sable/<game-name> (for example /bac-a-sable/pong).

What next?

To keep your game, publish it and make it grow: create it with your GitHub account, then follow the hello world tutorial to understand every line.

The sandbox's PHP runs in your browser (WebAssembly), never on the server.
