这是我玩蛇游戏的代码。我在队列模块方面遇到了问题，因为每当我试图输入它不会输入的东西时，如果我去检查队列大小，它会在每次勾选时更新自己，如果它是空的，但一旦其中有东西就会停止。
我只能向左移动(其他方向不允许我移动(，当我向左移动后按下某个东西时，它会停在原地，我必须终止程序。
我想知道我的代码是否有问题(可能(，但如果是这样的话，为什么它让我向左移动，而不是任何其他方向。任何帮助都将不胜感激此外，如何使帧速率更平滑？
我认为这是因为您正在消耗第一个if Q.get() == "left"上的队列，所以elif Q.get() == "right"正在处理队列中的下一个项目，而这个项目通常只是空的。
在测试之前，将从队列中提取的项目放入本地变量中
next_command = Q.get()
if next_command == "left" and direction != "right":
x1_change = -snakeblock
y1_change = 0
direction = "left"
elif next_command == "right" and direction != "left":
x1_change = snakeblock
y1_change = 0
direction = "right"
elif next_command == "up" and direction != "down":
