Game Loop

Definitions

The central loop in a game engine that continuously processes input, updates game state, and renders frames. Typically runs 30-60+ times per second, with fixed-timestep updates for physics and variable rendering.
In plain English: The heartbeat of every video game — a loop that checks what buttons you pressed, moves everything, and draws the screen, over and over, sixty times a second.
Example: "The game loop runs input, update, render every frame — if update takes too long, you drop frames."
