Cursor Effects
cursor-effects is a JavaScript library and effect engine designed to implement physics-based cursor trails and floating visual effects in web browsers. It provides a framework for adding interactive graphical overlays that follow the user pointer.
The system specializes in spawning particle trails, physics-based floating emojis, and pointer-tracking text strings. These animations utilize spring-based physics simulations to create organic reactions and dispersal patterns as the cursor moves.
The library manages the entire lifecycle of visual elements, from coordinate-based pointer tracking and DOM injection to the automatic removal of particles. Animation frames are updated via a request animation loop to ensure motion aligns with the browser's native refresh rate.
Features
- Cursor Animations - Replaces or augments the standard pointer with trailing particles, floating emojis, and dynamic shapes.
- Spring Physics - Simulates tension and damping to create organic, bouncy reactions to cursor movements.
- Cursor Effect Engines - Spawns emojis and shapes that react to cursor movement using springy physics and dispersal patterns.
- RequestAnimationFrame Loops - Uses the browser's native refresh rate to update animation frames and particle positions for smooth motion.
- JavaScript Animation Libraries - Provides a lightweight JavaScript library for creating high-performance particle trails and cursor animations.
- Particle Pool Managers - Manages the birth, movement, and automatic removal of particle effect instances based on their lifespan.
- Browser Visual Effects - Implements nostalgic and playful graphical elements and interactive overlays within the web browser.
- Pointer Coordinate Mappers - Maps real-time mouse coordinates to drive the position of active visual effects across the viewport.
- Cursor-Driven Visual Effects - Implements dynamic visual changes and effects that react in real-time to mouse coordinates.
- Dynamic Element Injection - Dynamically creates and appends temporary HTML elements to the page body to render trail particles.
- Floating Emoji Effects - Spawns physics-based emojis or characters that follow the mouse with springy dispersal patterns.
- Runtime Configuration Objects - Provides a centralized configuration object to dynamically update animation speed and colors at runtime.
- Trail Generation - Generates sequence-based trailing particles that follow the pointer with adjustable speed and lifespan.
- Interactive Web Animations - Adds visual flair through interactive animations that react dynamically to mouse movements.
- User Interface & Experience - Enhances the feel of web interfaces with interactive elements and motion that follow the user pointer.
- Pointer-Tracking Text - Provides custom colored text strings that dynamically track and render at the position of the user pointer.
- JavaScript 框架汇总 - Listed in the “JavaScript 项目” section of the Great Open Source Project awesome list.
