Python 如何使用我创建的网格中的w、a、s、d键确定玩家圆圈移动的位置

好的，我的最后一个项目是创建一个地下城爬虫，我在玩家移动的地方设置了一个网格，到目前为止，我正在完成GUI，然后将其余文件与攻击功能链接在一起。无论如何，我的问题是我的玩家圈不会在我创建的网格中移动，如果你不知道我的意思，下面是代码：

gui.py

try:
    from tkinter import *

except ImportError as err:
    print('a', err)

from player import *

class SimpleGUI:
    def __init__(self):
        self.window = Tk()
        self.window.title('Final Project')
        self.window.protocol('WM_DELETE_WINDOW',self.exit)
        self.canvas = Canvas(self.window,
                             width = 245,
                             height = 550,
                             bg = 'white')
        self.canvas.pack()

        self.player = Player()

        self.canvas.focus_set()
        self.canvas.bind('w', self.w_key)
        self.canvas.bind('a', self.a_key)
        self.canvas.bind('s', self.s_key)
        self.canvas.bind('d', self.d_key)


        self.running = True
        self.menu = Menu

        self.bt1 = Button(self.window,
                         text = 'Start',
                         command = self.menu)
        self.bt1.pack()




        self.mainloop()
        self.window.mainloop()

我不确定你的问题是什么。我复制了你的代码，当我运行你的项目时，红色的圆圈会随着wasd键适当移动。缺少适当的碰撞是问题吗？

这不是如何在tkinter中制作动画。您不应该用自己的while循环替换内置的

mainloop

要制作动画，请只绘制一次棋盘。然后，创建一个函数来更新电路板。最后，在之后定期调用该函数。这将允许您的UI响应，同时保持板的最新状态

换句话说，与此相反：

def mainloop():
    while self.running:
        ...
        self.canvas.after(30)
        self.canvas.update()

。。。你应该这样做：

def update_display():

    <update the display based on current information>

    if self.running:
        # update the screen again in 30 ms
        self.after(30, update_display)

def update_display（）：
如果自动运行：
#30毫秒后再次更新屏幕
self.after（30，更新显示）

对于“更新显示”部分，您可以使用canvas

move

和/或

coords

方法来移动椭圆。没有必要在每次迭代过程中删除并完全重新绘制——只需重新绘制已更改的内容即可。对玩家来说也是如此——画一次，然后再移动它

---

使用此体系结构，您的应用程序将执行得更好

对不起，我想让圆完全进入正方形，如果你把它一直移动到网格的右边，它会偏离几个像素。很抱歉搞混了问题是我需要圆正好进入网格上正方形的中间，只需编辑圆上的填充，将其从黑色改为白色，你就会更好地理解我的意思，而且，我需要找到一种方法，确保圆点只能进入黑色正方形，而不能进入其他任何地方，有什么好办法吗？@MylesTaft:你有没有试过简单地用一点数学来确保坐标按你想要的方式对齐？
