Create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts.
thinking
The user wants me to create a fireworks display as a single-page web app. The requirements are: 1. Full-screen canvas 2. Clicks launch shells 3. Shells explode into particle bursts 4. Particles are affected by gravity 5. Particles fade out over time 6. Everything in one index.html file with inline CSS and JS 7. No external resources Let me create this step by step: - HTML structure with a full-screen canvas - CSS to make the canvas full-screen - JavaScript to handle: - Canvas setup - Mouse click events to launch shells - Shell physics (launching upward, then exploding) - Particle system for explosions - Gravity effect on particles - Fading effect on particles - Animation loop I'll write this as a complete, self-contained index.html file.
I'll create a self-contained fireworks display app with interactive shell launching, particle physics, and gravity effects.

The user asked me to create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts. I've just created the file, but let me verify it was created correctly and maybe test it or check if there are any issues. Actually, looking at my code, I should double-check a few things: 1. The canvas is full-screen - yes, I set it to window.innerWidth and window.innerHeight 2. Clicks launch shells - yes, I have a click event listener 3. Shells explode - yes, the Shell class has an explode() method 4. Gravity affects particles - yes, I set gravity = 0.05 in Particle class 5. Particles fade - yes, I'm using alpha based on life/maxLife 6. Everything is in one file - yes, CSS in style tag, JS in script tag 7. No external resources - yes, everything is inline The code looks good, but let me verify the file was created.
I've created a self-contained fireworks display app in `/workspace/index.html`. Here's what it includes: **Features:** - **Full-screen canvas** with dark background - **Click to launch** - Click anywhere to launch a firework shell from the bottom - **Mouse movement** - Lightly holding mouse down/moving creates trailing fireworks - **Touch support** - Works on mobile devices - **Auto-launch** - Random fireworks automatically launch every ~1-2 seconds **Physics & Effects:** - **Shell trajectory** - Shells arc upward with gravity, then explode at their peak - **Gravity** - Particles are affected by gravity (0.05 acceleration downward) - **Fade effect** - Particles fade out based on remaining life - **Trail effects** - Both shells and particles leave glowing trails - **Particle types** - Multiple explosion patterns (circular, double ring, chrysanthemum) - **Sparkle particles** - White sparkles mixed in for extra visual flair - **Screen fade** - Slight fade trail effect creates natural-looking persistence **Visual Details:** - 9 different color options (red, green, blue, yellow, magenta, cyan, orange, pink, purple) - Glow effects on shells and particles - Particle sizes vary for depth effect - Life spans vary for natural dissipation Open `index.html` in a browser to see the fireworks display!
