Question

我是pygame的新手，所以我的代码有点乱，但我希望你能帮助我。当我做一个精灵移动它工作正常，但如果我真的快速切换键，或者如果我按下跳转按钮放开，我的精灵停止移动。

import shelve

pygame.init()
shelfFile = shelve.open('save_game')

我认为问题在于，在某些地方，你写了y = +20而不是y += 20。如果您希望y增加20个单位，请执行y += 20，如果您希望将y设置为值20，请执行y = 20（与y = +20相同{1}}）。我不知道你要做什么，因为我没有你的png文件，我无法运行程序看看会发生什么。此外，如果它甚至是一个无意的错误，你对负面和代码的其他部分做了同样的事情。

这不是一个真正的错误，如果没有纠正它会起作用，但你也拼错了一些东西（如果它是故意的，请忽略它。）

sise应该是大小，高度应该是高度， cutseane应该是过场动画......

还有其他错误。如果所有这些都有效并且它们不仅仅是拼写错误，那么您可能正在使用我不知道的某些版本的python。

你的事件循环真的搞砸了，应该重组。不应在事件循环中调用keys = pygame.key.get_pressed()，而应在外部while循环中调用key.get_pressed。我有一个最小的例子来向您展示一种进行移动和事件处理的方法（仅使用事件循环且没有import sys import pygame pygame.init() screen = pygame.display.set_mode((700, 600)) clock = pygame.time.Clock() player = pygame.Surface((30, 30)) player.fill((120, 240, 90)) px = 100 py = 200 x_speed = 0 y_speed = 0 while True: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() sys.exit() elif event.type == pygame.KEYDOWN: # If player is on the ground, jump (in more advanced # games you need collision detection instead >= 480). if event.key == pygame.K_UP and py >= 480: y_speed = -20 elif event.key == pygame.K_RIGHT: x_speed = 10 elif event.key == pygame.K_LEFT: x_speed = -10 elif event.type == pygame.KEYUP: # If player is moving right, stop him. if event.key == pygame.K_RIGHT and x_speed > 0: x_speed = 0 # If player is moving left, stop him. elif event.key == pygame.K_LEFT and x_speed < 0: x_speed = 0 # Don't jump too high. if py <= 200: y_speed = 20 # Don't go below y = 480. if py >= 480: py = 480 # Move the player. px += x_speed py += y_speed # The Wall. if px <= 0: px = 0 if px >= 630: px = 630 screen.fill((50, 50, 50)) screen.blit(player, (px, py)) pygame.display.flip() clock.tick(30)）。

如果我按下一个键而另一个键太快，我的pygame精灵会停止移动
