Create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts.

The user wants a full-screen fireworks display with the following features: 1. Full-screen canvas 2. Clicks launch shells that explode 3. Particles are affected by gravity 4. Particles fade over time I need to create a single index.html file with: - HTML5 canvas element - CSS for full-screen styling - JavaScript for: - Canvas setup and resizing - Firework/Shell class that launches upward - Particle class for explosion effects - Gravity physics - Fading/fading out particles - Click event handling - Animation loop Let me create this complete, self-contained file.
I'll create a full-screen fireworks display with click-to-launch shells, gravity-affected particles, and fading effects. Let me build this complete single-page app.

I've created a complete fireworks display in a single index.html file. The app includes: 1. Full-screen canvas with a dark gradient background 2. Star field with twinkling effect 3. Shell class that launches rockets upward with trailing effect 4. Particle class for explosion effects with: - Gravity physics (particles fall down over time) - Fading/alpha decay - Trail effects - Air resistance 5. Click/touch handling to launch fireworks at target location 6. Auto-launch feature for demo purposes 7. All CSS and JS inline, no external dependencies The fireworks will: - Launch from bottom of screen when clicked - Travel to the click position - Explode into colorful particles - Particles are affected by gravity and fade out over time - Each explosion has 80-150 particles plus sparkle particles - Colors are randomly selected from a vibrantpalette
I've created a complete fireworks display in a single `index.html` file. Here's what it includes: **Features:** - **Full-screen canvas** with a dark night sky gradient background - **Twinkling stars** in the background for atmosphere - **Click-to-launch** - click anywhere to launch a firework shell to that position - **Touch support** for mobile devices **Physics & Effects:** - **Shells** launch upward with trailing sparks, slowing down as they rise - **Explosions** create 80-150 colorful particles per burst, plus white sparkles - **Gravity** pulls particles downward naturally - **Air resistance** gradually slows particle movement - **Fading** particles smoothly fade out over time - **Trails** each particle leaves a fading trail behind it **Colors:** - 11 vibrant firework colors randomly selected (red, green, blue, yellow, magenta, cyan, orange, pink, lime, white, purple) **Demo:** - Auto-launch feature occasionally fires random fireworks for demonstration Just open the file in a browser and click anywhere on the screen to launch fireworks!
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
Fireworks launch and explode with colorful gravity-affected particle bursts on click, wheel, and even key presses; drag alone barely triggers anything.

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.
