Create a full-screen flocking simulation of boids using separation, alignment, and cohesion, drawn as oriented triangles that steer smoothly and flee from the mouse cursor.
thinking
I need to create a full-screen flocking simulation (boids) with the following features: 1. Separation, alignment, and cohesion behaviors 2. Oriented triangles that steer smoothly 3. Flee from mouse cursor 4. Full-screen canvas 5. All in a single index.html file with inline CSS and JS Let me start by writing the HTML structure with embedded CSS and JavaScript.

The index.html file has been created with a complete boids flocking simulation. Let me verify it's all there and working. The file includes: 1. Full-screen canvas with responsive resizing 2. Boid class with separation, alignment, cohesion behaviors 3. Mouse flee behavior 4. Smooth steering and oriented triangles 5. Visual effects like trails, glow, and mouse pulse 6. Click to add new boids 7. Controls panel explaining the behaviors The simulation should be fully functional and self-contained with no external resources. Let me just check if there's anything else needed, but the requirements are all met.
I've created a complete boids flocking simulation in a single `index.html` file. The simulation includes: - **Core Behaviors**: Separation (avoid crowding), Alignment (match heading), Cohesion (move toward group center) - **Mouse Interaction**: Boids flee from your cursor with a pulsing danger zone effect - **Visuals**: Oriented triangles with gradient colors, glow effects, and smooth trailing motion - **Controls**: Click anywhere to add new boids; move cursor to scare them - **Responsive**: Full-screen canvas that adapts to window size The simulation runs at 60fps with 150 boids by default. All code is self-contained in one HTML file with inline CSS and JavaScript.

Perfect, the index.html file is present in the current directory. The task is complete - I've created a full-screen flocking simulation with all the requested features: 1. Separation, alignment, and cohesion behaviors 2. Oriented triangles that steer smoothly 3. Flee from mouse cursor 4. All in a single self-contained HTML file Let me just confirm there's nothing else needed and then finish.
The boids flocking simulation is complete. The `index.html` file is ready and contains: - 150 initial boids with smooth triangular appearance - Full separation/alignment/cohesion flocking logic - Mouse cursor avoidance with visual danger zone - Gradient colors, glow effects, and motion trails - Click-to-add-boid interaction - Responsive full-screen canvas To run, simply open `index.html` in a web browser.

The file looks complete. The HTML structure is there with proper styling, and the JavaScript contains the Vector class, Boid class with all behaviors (separation, alignment, cohesion, flee), and the animation loop. The task is complete - I've created a full-screen boids flocking simulation meeting all the requirements. Let me just summarize what was created: 1. A single self-contained index.html file 2. Full-screen canvas with responsive design 3. Boids with separation, alignment, and cohesion behaviors 4. Oriented triangles with smooth steering 5. Mouse cursor flee behavior with visual effects 6. Click-to-add-boid interaction 7. Beautiful visuals with gradients, glow, and trails Everything is in place. The task is complete.
The flocking simulation is complete. The `index.html` file contains a full-screen boids implementation with: - **Separation/Alignment/Cohesion**: The three core flocking rules with weighted forces - **Oriented Triangles**: Smoothly turning triangular boids with gradient colors and glow effects - **Mouse Flee**: Boids actively avoid the cursor with a pulsing danger zone visualization - **Interactive**: Click anywhere to add new boids; watch them flock dynamically - **Responsive**: Automatically adapts to window resizing The simulation is visually appealing with motion trails, color-coded boids, and a dark gradient background. All code is self-contained in a single HTML file with no external dependencies.

EVALUATION
Boids flock and animate continuously with a red cursor glow causing visible fleeing/scattering behavior.

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.
