Now that you have a player class, you can create and display a player. There's no way to move him around just yet, he'll just sit there on the screen, see the next article in this series to learn how to do that.
Creating a player is very easy, just call player = Player.new. Drawing the player is just as easy--just call player.draw(screen). However, the order in which you draw things is important, since everything you draw writes over the things you previously drew. If you were to draw the background last it would draw over everything else you've drawn since it takes up the whole screen. Construct the player before your main loop, near where you loaded the background image and, just after you draw your background image, display the player in your main loop.
def main_loop
screen = Screen.new [640, 480]
queue = EventQueue.new
clock = Clock.new
clock.target_framerate = 30
background = Surface['background.png']
player = Player.new
loop do
clock.tick
queue.each do|e|
return if e.is_a? QuitEvent
end
background.blit( screen, [0,0] )
player.draw( screen )
screen.update
end
ensure
Rubygame.quit
end
