pygame mouse.get_pos() not working

mouse, pygame, python

Solution

Pygame will constantly dispatch events while it's running. These need to be handled in some way or pygame will hang and not do anything. Simplest way to fix it is by adding this to your main loop:

...
    while True:
        for event in pygame.event.get():
            pass                                             
        print pygame.mouse.get_pos()
...

Problem

I can't get a very simple pygame script to work: ``` import pygame class MainWindow(object): def __init__(self): pygame.init() pygame.display.set_caption('Game') pygame.mouse.set_visible(True) # pygame.mouse.set_visible(False) # this doesn't work either! screen = pygame.display.set_mode((640,480), 0, 32) pygame.mixer.init() while True: print pygame.mouse.get_pos() pygame.mixer.quit() pygame.quit() MainWindow() ``` This just outputs (0,0) as I move the mouse around the window: ``` (0, 0) (0, 0) (0, 0) (0, 0) (0, 0) ``` Can anyone check this? Edit - fixed code: ``` import pygame class MainWindow(object): def __init__(self): pygame.init() pygame.display.set_caption('Game') pygame.mouse.set_visible(True) # pygame.mouse.set_visible(False) # this doesn't work either! screen = pygame.display.set_mode((640,480), 0, 32) pygame.mixer.init() while True: for event in pygame.event.get(): if event.type == pygame.MOUSEMOTION: print pygame.mouse.get_pos() pygame.mixer.quit() pygame.quit() MainWindow() ```
