3.5 Example

Here is an example that implements all that we learned in this chapter. It will check for two different types of keystrokes: the KEYUP (a key is let go of) and the KEYDOWN (a key is pressed). However, because pygame.KEYDOWN is blocked, the application won't be able to detect a key being pressed. It will only print "Up up up!" when the key is let go of.


import pygame
pygame.init()
 
flag = pygame.locals.RESIZABLE
window = pygame.display.set_mode((500, 400), flag)
 
pygame.event.set_blocked(pygame.KEYDOWN)
 
run = True
while run:
  for event in pygame.event.get():
    if event.type == pygame.QUIT:
      # if event is QUIT
			run = False
    if event.type == pygame.KEYUP:
      # if event is KEYUP
      print(“Up up up!”)
    If event.type == pygame.KEYDOWN:
      # this will never happen because KEYDOWN is blocked
      print(“Down down down!”)
 
pygame.quit()
