Question

我正在使用python 3.4.3。在pygame事件中遇到一些麻烦。按下提到的键（向上，向下，向左或向右）后，99％的时间，程序没有反应。绑定一个（或多个）密钥似乎是解决这个问题的唯一方法，但即使这样也是不可靠的。

代码：

import pygame
pygame.init()

size = width, height = 1024, 768
screen = pygame.display.set_mode(size,pygame.FULLSCREEN)
g = pygame.image.load(
        'X:\\Projects\\Rogue\\Game Project\\src\\img\\Tiles\grass.JPG')
player = pygame.image.load('untitled.PNG')
pygame.display.set_caption('WINDOW_NAME')

run = True
def resolve(x,y):#x=32 y=20
    return (x*32, y*32)

def get_tiles():
    tiles = []
    for y in range(0,20):
        for x in range(0,32):
            tiles.append(resolve(x,y))
    return tiles

p = [5,5]

def draw_player(p):
    screen.blit(player, resolve(p[0],p[1]))

clock = pygame.time.Clock()

def move(direction):
    if direction == 'U':
        if p[1]-1 < 0:
            print('fail')
        else:
            p[1] = p[1] - 1
    elif direction == 'D':
        if p[1] + 1 > 20:
            print('fail')
        else:
            p[1] = p[1] + 1
    elif direction == 'L':
        if p[0] - 1 < 0:
            print('fail')
        else:
            p[0] = p[0] - 1
    elif direction == 'R':
        if p[0] + 1 > 32:
            print('fail')
        else:
            p[0] = p[0] + 1

def event_handler():
    for event in pygame.event.get():
        print('event:',event)
        if event.type == pygame.KEYDOWN or event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                quit()
            elif event.key == pygame.K_p:
                print('fish')
            elif event.key == pygame.K_UP:
                move('U')
            elif event.key == pygame.K_DOWN:
                move('D')
            elif event.key == pygame.K_LEFT:
                move('L')
            elif event.key == pygame.K_RIGHT:
                move('R')
            elif event.type == pygame.MOUSEBUTTONDOWN:
                print('a')
                print(pygame.display.get4_driver())
                for item in pygame.display.list_modes():
                    print(item)

def render(sprites):
    for item in sprites:
        screen.blit(g,item)

from random import randint

while run:
    #if len(pygame.event.get()) > 0:
    print(p)
    print(pygame.event.get())
    event_handler()
    render(get_tiles())
    draw_player(p)
    #screen.fill(255,255,255)#wipe to black
    pygame.display.flip()#screen updates all areas that have been blited
    clock.tick(30)#30 FPS for now

pygame.quit()

此外，pygame.quit()对我没有任何作用，因此逃脱的部分会立即杀死该程序。

摆脱print（pygame.event.get（））。摆脱事件循环中的or，因为您只是再次检查同一件事，所以它不会做任何事情，并且if语句检查鼠标按钮应该在if语句之外以检查击键。

pygame中的事件不起作用
