For demonstration purposes it's enough that it has 1-dimensional position. The game loop allows the game to run smoothly regardless of a user's input, or lack thereof. The central component of any game, from a programming standpoint, is the game loop. Game Loop pattern ensures that game time progresses in equal speed in all different hardware setups. It drives input process, internal status update, rendering, AI and all the other processes. Game loop is the main process of all the game rendering threads. This pattern is used in every game engine. This pattern decouples progression of game time from user input and processor speed.

It tracks the passage of time to control the rate of gameplay.

Each turn of the loop, it processes user input without blocking, updates the game state, and renders the game. A game loop runs continuously during gameplay.
