Fireworks! — Pen Particle Explosion Showcase Create dazzling firework displays and explosive visuals with Scratch’s pen extension! This interactive demo blends physics, randomization, and clone mechanics to simulate hundreds of particles bursting from a single click. With gravity, resistance, and bounce detection, each firework feels alive—making it perfect for visual experiments! Features: Click-based particle launch with randomized velocity and direction Gravity + resistance simulation for realistic motion Edge and level collision detection for bouncy particles Clone-based rendering with dynamic pen size and color Optional sparkle sounds for extra pizazz ? Update Log v1.3 – July 2025 Added bounce-on-level collision physics Updated pen color sync with sprite effects Sparkle sounds now randomized on impact v1.2 – June 2025 Tweaked gravity and resistance constants for smoother motion Refactored particle creation into modular blocks Improved cleanup: clones auto-delete on inactivity v1.0 – May 2025 Initial launch: mouse-triggered fireworks with basic physics ?️ Pen stamping for trails and glow effects ? Particle motion using sine/cosine burst logic
