Mẹo tạo Hiệu ứng Cát Rơi (Falling Sand) cực đẹp trong Scratch

Are you frustrated by the 300-clone limit causing lag in Scratch? Forget the old methods! In this video, Dare2Share will guide you on how to "hack" Scratch's limit to create a super-smooth physical falling sand effect at 60 FPS using techniques from real software engineers! We'll decode three incredibly interesting algorithms: 1️⃣ Matrix Transformation: Flattening a 2D space into a one-dimensional List. 2️⃣ Cellular Automata: Programming "survival thinking" for thousands of sand grains. 3️⃣ Data-Driven Rendering: The secret to creating stunningly beautiful "terrain" effects without complex variables. Don't forget the challenge at the end of the video! After coding, leave your project link in the comments for everyone to admire. 📂 VIDEO RESOURCES: 🔗 Download image/background music/source code files: https://olacity.org ⏳ Main content (Timestamps): 0:00 - Super Smooth Physical Sand Falling: What's the Secret? 1:10 - Scratch Memory Hack: Creating a 4800-cell Matrix Grid 1:40 - Gravity Skeleton & "Fall Through the Bottom" Error 2:20 - Collision Rules: Teaching Sand Grains How to Find Their Way 3:10 - Coin Toss: The Mystery of Random Perturbation 3:50 - Unlocking Graphics (Pen Extension) 4:30 - Creating Interactive Sandblasting Brushes with the Mouse 5:06 - Data-Driven Rendering: The Ultimate Trick for Creating Stratigraphic Layers 5:25 - This Week's Achievement & Challenge for You! 🔥 ABOUT THE DARE2SHARE CHANNEL: This YouTube channel specializes in sharing advanced programming knowledge, algorithms, and tutorials on creating games from scratch.
