python - 检测 pygame 中的用户事件

Question

我有以下代码，我尝试在 pygame 中对用户事件使用react:

import pygame
from pygame.locals import *
from pygame.time import set_timer
from sys import exit

def timerFunc():
    print "Timer CallBack"

pygame.init()

screen = pygame.display.set_mode((640,480),0,32)
set_timer(USEREVENT+1, 1000)

while True:
    pressed_keys = pygame.key.get_pressed()

    if pressed_keys[K_SPACE]:
        exit()

    for event in pygame.event.get():
        print event
        if event == QUIT:
            exit()
        if event == USEREVENT+1:
            timerFunc()

不幸的是，timerFunc() 没有被执行，事件由 set_timer() 函数传播，因为在输出中我得到:

<Event(25-UserEvent {'code': 0})

您需要使用event.type属性:

for event in pygame.event.get():
    print event
    if event.type == QUIT:
        exit()
    if event.type == USEREVENT+1:
        timerFunc()
