为什么我的按键动作不正常

Question

我正在创建一个基本游戏，但我的代码中存在键盘响应的问题当您单击"开始"时，立方体将一直沿着您按下的箭头键的方向移动，但我希望它能移动您用箭头键按下的任何方向，如果没有按下任何键，它就会停止有人能告诉我我的代码中有什么错误以及如何正确处理吗？

这是代码：

Answer 1

问题是在game((中使用了两个事件循环。必须将所有事件添加到同一事件循环中。

所以，

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

for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
smerx = 1
if event.key == pygame.K_LEFT:
smerx = -1
if event.key == pygame.K_DOWN:
smery = 1
if event.key == pygame.K_UP:
smery = -1
if event.key == pygame.K_ESCAPE:
koniec()

if event.type == pygame.KEYUP:
if event.key == pygame.K_RIGHT or event.key == pygame.K_LEFT:
smerx = 0
if event.key == pygame.K_DOWN or event.key == pygame.K_UP:
smery = 0

这个^将变成

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

if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
smerx = 1
if event.key == pygame.K_LEFT:
smerx = -1
if event.key == pygame.K_DOWN:
smery = 1
if event.key == pygame.K_UP:
smery = -1
if event.key == pygame.K_ESCAPE:
koniec()

if event.type == pygame.KEYUP:
if event.key == pygame.K_RIGHT or event.key == pygame.K_LEFT:
smerx = 0
if event.key == pygame.K_DOWN or event.key == pygame.K_UP:
smery = 0

所以，基本上，我在代码中犯了一个错误，在game((中使用了(2x表示(。下次我将使用(for(时，我将检查它下面的命令是否在的同一周期中感谢的回答：(
