python - 我一直在 pygame 中开展一个项目，但即使没有出现错误，玩家的移动似乎也不起作用

问题描述

我需要准备好玩家的移动，我已经尝试从其他脚本中获取所需的代码，但即使没有出现错误，它似乎也无法正常工作，并且经过几次检查后代码似乎没问题。我正在使用的库是sys、pygame 和 glob。我正在关注本指南，但也对其进行了更改：https ://pythonprogramming.altervista.org/platform-game-in-detail-part-1/?doing_wp_cron=1603309265.4902870655059814453125

代码：

from pygame.locals import *
import pygame
import sys
import glob
map1 = """wwwwwwwwwwwwwwwwwwwwwwwwwwwww
w                           w
w                           w
w                           w
w                           w
w                           
w                           d
w            p               
w                           
w                           w
w                           w
w                           w
w                           w
w                           w
w                           w
wwwwwwwwwwwwwwwwwwwwwwwwwwwww"""

        elif (event.key == K_RIGHT):
            playerx += 5
        elif (event.key == K_UP):
            playery -= 5
        elif (event.key == K_DOWN):
            playery += 5






    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()




    pygame.display.update()
    clock.tick(120)

解决方案

只是你必须添加一个缩进块：

while True:
    tiles(map1)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

            DISPLAYSURF.blit(sprite, (playerx, playery))

        if event.type == KEYDOWN:
            if (event.key == K_LEFT):
                playerx -= 5
            elif (event.key == K_RIGHT):
                playerx += 5
            elif (event.key == K_UP):
                playery -= 5
            elif (event.key == K_DOWN):
                playery += 5
