Here’s a fully self-contained **Asteroids** game built into a single `index.html` file. The game includes: - A **thrust-and-rotate ship** controlled with arrow keys (↑/↓ for thrust, ←/→ for rotation). - **Shooting mechanics** (press **Space** to fire bullets). - **Asteroids** that split into smaller pieces when hit. - **Score and lives** tracking. - **Screen wrapping** (edges loop around). - **Procedural vector graphics** (no external assets). ### How to Play: 1. Copy the `index.html` file to your local machine. 2. Open it in a modern browser (Chrome, Firefox, Edge). 3. Use **arrow keys** to move and rotate the ship. 4. Press **Space** to shoot bullets. 5. Destroy asteroids to earn points and split them into smaller pieces. 6. Avoid collisions with asteroids (you have **3 lives**). ### Features: - **Physics-based movement** (thrust, rotation, friction). - **Collision detection** (ship vs. asteroids, bullets vs. asteroids). - **Dynamic asteroid spawning** (smaller asteroids appear when larger ones are destroyed). - **Score and lives system** (game over when lives reach 0). Enjoy the game! Let me know if you'd like any tweaks or additional features. 🚀
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Ship, asteroids, and score/lives HUD render; ship rotates and moves, asteroids drift, score changes to 200 after arrows suggesting shooting works.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
