Main Loop

Definitions

1. The central infinite loop in a program — particularly game engines, GUI applications, and servers — that repeatedly polls for input, updates state, and renders output. In games this is the tick loop running at a target frame rate; in GUIs it's the event dispatch loop.

   In plain English: The endless cycle at the heart of a program that keeps checking for things to do, processes them, and shows the result, over and over until you quit.

   Example: "The main loop runs at 60 Hz: poll input, step physics, render, present, repeat."
