Game Loop

The game loop is a fundamental programming pattern in game development that continuously updates the game state and renders graphics to create a real-time interactive experience. It typically involves three main phases: processing input, updating game logic (such as physics and AI), and rendering the output to the screen. This loop runs at a consistent frame rate to ensure smooth gameplay and responsiveness.

Also known as: Game Cycle, Main Loop, Render Loop, Update Loop, Game Engine Loop

Why learn Game Loop?

Developers should learn the game loop when building real-time interactive applications like video games, simulations, or graphical user interfaces that require continuous updates. It is essential for handling user input, managing game state changes, and synchronizing visual output, ensuring that games run smoothly across different hardware and platforms. Understanding this concept is crucial for optimizing performance and avoiding issues like lag or frame rate drops.
