I always wondered about the "mechanism" how games display the movement of an object on screen. Just for my curiosity (I have little experience in programming), how does the code/engine of the game (for e.g. the old Pong game) define the object that needs to be displayed on screen? As a variable that has value for x, y position and a certain colour for the pixel?
