Prompt for this run
Build a playable Asteroids-style game on a canvas using procedural vector graphics. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Use Left/Right to rotate the ship, Up to thrust, and Space to fire. Show the controls. The ship retains momentum and wraps around every screen edge; asteroids also wrap. - Spawn moving large asteroids. A bullet hit splits a large asteroid into smaller pieces; hitting a smallest piece removes it. Hits increase the score. - Start with three lives. A ship-asteroid collision removes one life, respawns the ship, and briefly protects it from immediate repeated damage. - Clearing all asteroids starts another wave. Losing all lives shows Game Over and a Restart control that resets score, lives, and the arena. - Keep projectile lifetime bounded and prevent gameplay keys from scrolling the page. Verify: Test rotation, thrust, and firing near the initial spawn. Check that the ship changes heading, gains momentum, and emits moving projectiles. Sample the scene to inspect screen wrapping when an object crosses an edge.

The game is now running, and the following behaviors have been verified: ### **Verified Functionality:** 1. **Initial Setup:** - The game canvas is displayed with a ship (green triangle) and asteroids (procedural polygons). - Score (`0`) and lives (`3`) are correctly shown. - Controls are displayed at the bottom. 2. **Ship Rotation:** - Pressing **Left/Right arrow keys** rotates the ship as expected. 3. **Thrusting:** - Pressing **Up arrow** propels the ship in the direction it is facing, and it retains momentum. 4. **Firing:** - Pressing **Space** fires bullets from the ship's nose. 5. **Asteroid Behavior:** - Asteroids spawn at random positions and move across the screen. - Asteroids wrap around screen edges. 6. **Collision Detection:** - Bullets collide with asteroids, splitting them into smaller pieces. - Hitting the smallest asteroid removes it and increases the score. 7. **Ship-Asteroid Collision:** - Colliding with an asteroid reduces lives and resets the ship position. - The ship briefly turns yellow (invulnerable) after a collision. 8. **Game Over and Restart:** - Losing all lives triggers a "Game Over" screen with a **Restart** button. - Clicking **Restart** resets the game. --- ### **Unverified or Potential Issues:** 1. **Screen Wrapping for Bullets:** - Bullets wrap around screen edges, but this behavior was not explicitly tested for edge cases (e.g., firing near corners). 2. **Asteroid Splitting Logic:** - Asteroids split into smaller pieces, but the exact behavior of spawning fragments could be further tested. 3. **Score and Lives Update:** - Score increments when hitting asteroids, but the exact values were not manually verified beyond basic functionality. 4. **Invulnerability Timer:** - The ship turns yellow after a collision, but the exact duration of invulnerability was not explicitly tested. --- ### **Next Steps (if time permits):** - Test edge-case wrapping for bullets and asteroids. - Verify score increments for different asteroid sizes. - Confirm invulnerability timer duration. The core gameplay loop is functional, and the game meets the required specifications.
