Python 为什么我的形状不随canvas.move（）移动？

我是python的完全初学者。我正在尝试制作一个游戏，这是我第一次使用Tkinter和canvas等。如果可能的话，我希望得到一个尽可能简单的答案，但我很感激任何答案。所以问题是，当我运行我的代码时，我没有得到任何错误，但是canvas.move（）没有任何东西在移动。子弹和广场都没有。但当我将print语句放在canvas.move所在的位置时，它会打印出来，显示代码正在到达该点，但canvas.move只是没有发生。 我的代码很乱，但在这里

如果（count在这里，我通过创建类清理了您的代码。现在您可以使用类属性而不是全局变量。我认为您缺少的是
canvas.focus\u force（）
方法，因此您可以使用键绑定。在将键绑定到小部件而不是根Tk对象时，您需要调用此方法

将tkinter作为tk导入
类别项目符号：
''画在画布上的黑色矩形物体。它可以左右移动''
定义初始化（自我、画布、坐标）：
self.canvas=画布
self.figure=canvas.create_矩形（*coords，fill=“black”）
self.canvas.bind（“，self.move\u left）
self.canvas.bind（“，self.move\u right）
def向左移动（自身，事件）：
self.canvas.move（self.figure，-5,0）
def向右移动（自身、事件）：
self.canvas.move（self.figure，5,0）
类级别（tk.Frame）：
''一个继承的tk.框架，就像一个场景，可以创建和销毁多个级别。''
#将根Tk传递到框架中，并调用super（）继承所有Tk.frame属性
定义初始化（自，根）：
super（）。\uuuu init\uuuu（master=root）
self.pack（）
self.canvas=tk.canvas（self，宽度=400，高度=400）
self.canvas.pack（）
#这种关注力可能是您所缺少的，因为它是特定于小部件的键绑定所需要的。
self.canvas.focus_force（）
def创建_项目符号（自我、协调）：
#在级别的画布小部件内创建Bullet类的实例
b=项目符号（self.canvas，coords）
#别忘了打包你的小部件，否则你就不能使用它们了
root=tk.tk（）
#创建关卡
级别1=级别（根）
#在画布内创建项目符号实例
级别1.创建_项目符号（（100125100））
root.mainloop（）
你的代码看起来很痛苦，重新配置将是一场噩梦。你应该创建一个
类Bullet
并用键绑定之类的方法填充它，还可以创建一个级别类。然后编写一个简单的脚本来移动单个形状或图像。我甚至不知道该Bullet呈现为什么。我的建议是试着四处移动首先谢谢你的回答。我知道看到这样一堆乱七八糟的代码一定会很恼火，但我是一个完全的初学者。我不知道什么课程或它是如何工作的，但我会尝试。如果这有助于它更好地工作，我愿意重新开始。你需要从编写一个新程序开始——a——那就是尝试移动单个项目。一旦您能够做到这一点，请尝试将您学到的知识应用到代码中。
