Class GameLoop

java.lang.Object
base.GameLoop
Direct Known Subclasses:
MultiLevelGame
public class GameLoop extends Object
Main class starting any game, contains main(). Apart from that, this class manages all non-logical functionalities which should be hidden from a game designer like:
  • Setting up windows, panels, buttons, action callbacks, ...
  • Reading keyboard inputs
  • Redrawing game window if necessary
  • managing the game time and calling the appropriate GameObject or Playground methods periodically, at every time step of the game.
There will normally never be a need to modify this file, a designer/game programmer should always redefine the GameObject and Playground classes and implement new functionality there. To make a long story short
