pygame.mouse.get_pos()不起作用(Python IDLE 3)

我正在尝试让python检测鼠标的位置。我的代码:

import pygames
pygame.init()
size = (700, 500)
screen = pygame.display.set_mode(size)
WHITE = (255,255,255)
screen.fill(WHITE)
pygame.mouse.set_pos([100,100]) #I didn't move my mouse so [0,100] should be the output
x_y = pygame.mouse.get_pos()
#I then run this program. Here is the output:
(0, 0)

我不知道出了什么问题。为什么坐标错了?

我不知道它为什么显示错误的坐标,但它似乎只发生在pygame窗口前面有另一个窗口(在本例中为IDLE窗口)。如果选择/聚焦pygame窗口并设置鼠标pos,pygame.mouse.get_pos()将返回正确的坐标。尝试在事件循环中设置鼠标位置(按 s 键):

import pygame

pygame.init()

size = (800, 500)
screen = pygame.display.set_mode(size)
pygame.mouse.set_pos([100,100])
WHITE = (255,255,255)
clock = pygame.time.Clock()

done = False
while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_s:
                pygame.mouse.set_pos([100,100])

    print(pygame.mouse.get_pos())
    screen.fill(WHITE)
    pygame.display.flip()
    clock.tick(30)

pygame.quit()

或者在命令行/终端中运行程序。
