Video games have been around for a few decades now and have seen tremendous growth over the years. The evolution of technology has allowed for more advanced and complex games to be developed, making it an industry worth billions of dollars. One crucial aspect of video games that is often overlooked by players is the gameloop. The gameloop is the heartbeat of video games and is responsible for the smooth flow of gameplay. In this article, we will take a deep dive into the world of gameloops and help you understand why it is so important.

Have you ever played a video game that felt off or unresponsive? If you have, then chances are the game’s gameloop was not up to par. A good gameloop can make or break a game, and in this article, we will show you why.


The gameloop one is the core process of a video game. It is the backbone that makes everything run smoothly and ensures that the player’s experience is as seamless as possible. Simply put, the gameloop is the code that runs repeatedly during the game’s runtime. It updates the game state, processes player input, and renders the graphics. The gameloop is essential to any video game as it is responsible for keeping the game running at a consistent frame rate.

The Components of a Gameloop

A game loop has two main components: the update loop and the render loop. The update loop is responsible for updating the game’s state, while the render loop is responsible for rendering the graphics. The update loop runs at a fixed time step, which is usually 60 times per second. The render loop, on the other hand, runs as fast as possible, which means that it is not tied to a fixed time step.

The Update Loop

The update loop is the most critical component of a game loop as it is responsible for updating the game’s state. The game’s state includes all the variables that define the game, such as the player’s health, position, and score. The update loop runs at a fixed time step to ensure that the game state is updated consistently, which makes the game run smoothly.

The update loop typically performs the following tasks:

  • Process player input: The update loop checks for any input from the player and updates the game state accordingly. For example, if the player presses the jump button, the update loop updates the player’s position to simulate a jump.
  • Update game logic: The update loop runs any game logic that needs to be updated, such as enemy movement or collisions.
  • Update game physics: The update loop updates the game’s physics, such as gravity and collisions, to ensure that the game behaves as expected.

The Render Loop

The render loop is responsible for rendering the graphics of the game. The render loop runs as fast as possible and is not tied to a fixed time step. The render loop typically performs the following tasks:

  • Draw the game objects: The render loop draws all the game objects on the screen, such as the player, enemies, and environment.
  • Apply visual effects: The render loop applies any visual effects, such as lighting or particle effects, to make the game look more visually appealing.
  • Display the game on the screen: The render loop displays the game on the screen, which the player sees and interacts with.
Why a Good Gameloop is Important

A good game loop is essential for any video game. It ensures that the game runs smoothly and responds to the player’s input in real time. A bad game loop can result in a game that feels unresponsive, laggy, or inconsistent. This can lead to a frustrating experience for the player
