我试图让我的角色一次向一个方向移动，它已经有效了......有点儿。字符的向上和向下运动是错误的 - 它要求用户持有 W / S / ↓ / ↑ 让玩家向上/向下移动。
我不知道为什么会发生这种情况，因为角色的左右运动工作正常 - 也就是说，角色会随着用户输入按下ONCE按钮移动（ A / D / ← / →）。请注意，这是Python 2.7。

上面的代码会发生什么，玩家会点击“玩游戏”按钮，游戏窗口会打开，玩家将控制一个绿色方块并向左，向右，向上和向下移动。
当玩家左右移动时，他们只需按 A 或 D 或←或→ ONCE让方块向左/向右移动。上下方向的情况不一样。只要用户提供输入，字符就会移动，即键 W 或 S 或↓或↑需要保持广场向所述方向移动。我怎样才能解决这个问题？

您的event.type==KEYUP:条件似乎是错误的：
设置正确后，您正在设置false上下移动...
检查此代码：
查看最近两篇if-else语句中的评论
elif event.type == KEYUP:
if event.key == K_ESCAPE:
pygame.quit()
sys.exit()
elif event.key == K_LEFT or event.key == ord('a'):
moveLEFT = True
moveRIGHT = False
moveUP = False
moveDOWN = False
elif event.key == K_RIGHT or event.key == ord('d'):
moveRIGHT = True
moveLEFT = False
moveUP = False
moveDOWN = False
elif event.key == K_UP or event.key == ord ('w'):
moveUP = True
moveLEFT = False
moveUP = False ##This line is faulty moveRIGHT=FALSE should be used instead
moveDOWN = False
elif event.key == K_DOWN or event.key == ord('s'):
moveDOWN = True
moveLEFT = False
moveUP = False
moveDOWN = False ##This line is faulty moveRIGHT=FALSE should be used instead
作为建议：
您可以在您认为错误的代码部分中使用打印语句
然后跟踪打印的记录，看看哪些东西工作正常，哪些不合适
这将让你对这个bug有一个公平的认识

看起来您复制代码以进行连续移动并尝试对其进行调整。如果您想在按下按钮后立即移动，请让您的KEYDOWN事件直接改变玩家的位置。
如果你想为动作制作动画，事情会变得更复杂：你必须有两种状态：移动和站立。站立时，您会侦听KEYDOWN事件，然后触发所需方向的移动（如果有）。如果移动，你会忽略KEYDOWN事件（或者如果你想要真正提高它们，可以将它们存储起来），并在到达目标方格后再次切换到站立状态。
此外，如果你想支持两种传输模式（按键或按住键），你将不得不添加额外的逻辑...也许检查pygame.key.get_pressed（），看看你是否应该从移动到转移，或者继续移动另一个方格。
