pygame.init()

#set up the window

• pygame.locals incluiye constantes como QUIT o K_ESCAPE

• Utilizamos sys.exit() para salir “suavemente” del programa

#set up the text
text = basicFont.render('Hello world!',True,WHITE,BLUE)
textRect = text.get_rect()
textRect.centerx = windowSurface.get_rect().centerx
textRect.centery = windowSurface.get_rect().centery

#draw the white background onto the surface
windowSurface.fill(WHITE)

#draw a green polygon onto the surface
pygame.draw.polygon(windowSurface,GREEN,((146,0),(291,106),(236,277)))

#draw some blue lies onto the surface
pygame.draw.line(windowSurface,BLUE,(60,60),(120,60),4)
pygame.draw.line(windowSurface,BLUE,(120,60),(60,120))
pygame.draw.line(windowSurface,BLUE,(60,120),(120,120),4)

#draw a blue circle onto the surface
pygame.draw.circle(windowSurface,BLUE,(300,50),20,0)

• Si no elimino pixArray, estará en estado bloqueado

• Elimino pixArray para poder manejar el objeto Surface a través del método

  blit ()

• El blit () solo modifica la memoria, pero para actualizar la pantalla debo

  dar display.update ()

• No olvides dar pygame.quit ()
