Game Loop

A game loop is a continuous loop that runs an Update() method and a Draw() method. Below is the simplest example of a game loop:

public void GameLoop {

   while (true)
   {
       Update();
       Draw();
   }

}

In practice game loops may have a lot more code. They may wait a certain amount of time between passes, do less processing on certain passes than others, contain exit logic, etc.

There are two main types of game loops:

Fixed Step - the loop processes equal intervals of game time Variable Step - the loop processes varying intervals of game time
