Real Life Examples of Game Loops in Popular Video Games

📚 Quick Study Guide

• ⏱️ A game loop is the continuous execution cycle in a video game that updates the game state, processes input, and renders output.
• 🔄 The basic structure involves input handling, updating game logic, and rendering the scene.
• 🎮 Popular games like *Super Mario Odyssey*, *Minecraft*, and *Fortnite* all rely on efficient game loops.
• 📈 Optimization is crucial. Techniques like fixed time steps and frame rate capping are often used.
• 📐 Physics calculations, AI behavior, and user interactions are all managed within the game loop.
