Snake Rewind: Building a Retro Snake Game in C with Raylib

Currently Playing: Shine On: Adding a Bloom/Glow Shader [Snake Rewind Ep 7]

✨ In Episode 7 of *Snake Rewind* we dive into post processing and implement a glowing *bloom shader* to give our game a punchy cinematic look. We take inspiration from an article from https://learnopengl.com and implement it in Raylib using a multi pass blur pipeline. The result? Glowing food, radiant UI and a pixel perfect retro vibe. 🎮 What we cover: - Creating a brightness threshold pass - Applying multi pass Gaussian blur (horizontal and vertical passes) - Compositing blurred highlights with additive blending - Using multiple `RenderTexture2D` targets for clean post processing - Controlling bloom strength and softness This effect gives the game visual depth and polish while keeping the aesthetic crisp and retro. 📺 Full Snake Rewind Series Playlist: https://www.youtube.com/playlist?list=PLI7p1zrAYQeUb67kPtsyduLk1aJChzIQZ 📖 Companion Blog Post: https://letsreinventthewheel.github.io/blog/snake-rewind-ep7/ 🧠 Source code: https://github.com/letsreinventthewheel/snake-rewind Snake Rewind isn't just a remake. It is Snake with a twist: - 🐍 Clone snakes that retrace your path - ✨ Retro shaders: bloom, scanlines, chromasep - 🎮 Reactive UI, game feel, and juicy feedback - 🎧 Music and SFX polish (hopefully we can find free sounds) 💬 Got questions?
