Premium Companion Features

Discover the engineering details behind Web Pets that make it the ultimate desktop accessory.

🎭

4 Movement Behaviors

Choose from standard horizontal meets, edge-to-edge cross-overs, lifelike dynamic random patrols, or bouncy retro diagonal bounces.

⚡

Fully Non-Blocking

Overlay container blocks 0% of clicks. Children settings map direct clicks to trigger heart emojis, while page clicks call the pets to run to the spot.

🛡️

Shadow DOM Isolation

Fully isolates HTML layouts inside separate Shadow Roots. Host websites' styles can never corrupt or leak into the pixel art sprites.

🔄

Dynamic Resize Scaling

Calculates paths using fractional ratios. Window resizing dynamically scales walking target coordinates on the fly.

Clean ES6 Engine API

Built with highly-structured, modular JavaScript. Swapping hardcoded profiles with database fetches is straightforward.

// Centralized profile structure ready for Google CWS and Firebase integrations const PET_CONFIGS = [ { petId: "neko-cat", spritePath: "assets/cat.gif", speed: 1.5, scale: 2.0, path: [[0.1, 0.8], [0.5, 0.8]] } ]; // Instantiates and begins tracking ticks on requestAnimationFrame const cat = new WebPet({ spriteUrl: chrome.runtime.getURL(PET_CONFIGS[0].spritePath), path: PET_CONFIGS[0].path });
