Bouncing balls in a heptagon · minimax-m2.1
Show 20 numbered balls (1 to 20) dropping from the center of a heptagon that spins 360 degrees every 5 seconds. The balls are affected by gravity and friction, collide with each other, and bounce realistically off the rotating walls; show each ball's spin via the rotation of its number. Implement all collision detection yourself.

The user wants a physics simulation with: 1. 20 numbered balls (1-20) dropping from the center 2. A heptagon (7-sided polygon) that spins 360° every 5 seconds 3. Gravity and friction affecting the balls 4. Ball-to-ball collisions 5. Ball bouncing off the rotating walls 6. Each ball shows its number and rotates with the ball's spin Let me create a self-contained HTML file with canvas-based physics simulation. Key components: 1. Canvas setup 2. Heptagon rendering with rotation 3. Ball physics (position, velocity, angular velocity) 4. Gravity and friction 5. Collision detection: - Ball-to-ball collision - Ball-to-wall collision (with rotating walls) 6. Ball rendering with number rotation Let me implement this step by step.

I've created a complete physics simulation with: 1. **20 numbered balls (1-20)** that drop from the center 2. **A heptagon** (7-sided polygon) that spins 360° every 5 seconds 3. **Gravity** affecting all balls 4. **Friction** (both linear and angular) 5. **Ball-to-ball collisions** with realistic bounce 6. **Ball-to-wall collisions** with the rotating heptagon walls 7. **Each ball's spin** is shown via rotation of its number The implementation includes: - Custom collision detection for ball-to-ball (using distance checks and momentum conservation) - Custom collision detection for ball-to-wall (using line segment distance and handling rotating walls) - Proper physics with restitution (bounciness), gravity, and friction - Visual effects like gradients on balls and glowing heptagon walls - Depth sorting so balls draw in correct order The file is self-contained with all CSS and JavaScript inline, no external resources.
I've created a complete physics simulation with: - **20 numbered balls (1-20)** dropping from the center - **Spinning heptagon** (7 sides) rotating 360° every 5 seconds - **Gravity** pulling balls down - **Friction** (linear and angular) for realistic deceleration - **Ball-to-ball collisions** with momentum conservation and bounce - **Ball-to-wall collisions** accounting for the rotating walls' velocity - **Spin visualization** - each ball's number rotates with its angular velocity Key physics features: - Custom collision detection for both ball-ball and ball-wall interactions - Restitution (bounciness) on all collisions - Angular momentum transfer from wall rotation to ball spin - Multiple collision iterations for stability - Automatic containment check to keep balls inside the heptagon The heptagon has a glowing cyan border and the balls have a 3D gradient effect with gold borders. The simulation runs smoothly at 60fps with proper delta-time physics.

The file is created and ready. It's a self-contained HTML file with all CSS and JavaScript inline. The simulation should work when opened in a browser.
The file is ready at `/tmp/ws/index.html`. Open it in a browser to see the balls drop, collide, and bounce off the spinning heptagon walls while their numbers spin with each ball's rotation.
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
Heptagon spins with 20 numbered balls settling under gravity, showing rotation and pile-up along walls; input has minimal effect but simulation runs correctly.

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.
