问题描述

我正在尝试构建一个简单的 Connect Four 与 Python(2.7)

I am trying to build a simple game of Connect Four with Python(2.7)

我创建了一个板，它由一个简单的多维 Python 列表组成.
我的董事会列表如下所示:

I have created a board, that consists of a simple multidimensional Python list.
My Board list looks like this:

board = [
    [_,_,_,_,_,_,_,_,_,_],
    [_,_,_,_,_,_,_,_,_,_],
    [_,_,_,_,_,_,_,_,_,_],
    [_,_,_,_,_,_,_,_,_,_],
    [_,_,_,_,_,_,_,_,_,_],
    [_,_,_,_,_,_,_,_,_,_],
    [_,_,_,_,O,_,_,_,_,_],
    [_,_,_,_,X,_,_,_,_,_],
    [_,_,_,_,X,O,_,_,_,_],
    [_,_,_,_,X,O,_,_,_,_],
]

如果 X 是 Player1 而 O 是 Player2(或计算机).

Were X is Player1 and O is Player2 (or Computer).

现在，我为 GUI 创建了一些基本代码，如下所示:

Now, I have created some basic code for the GUI, like this:

# Connect 4 Game
import Tkinter

screen = Tkinter.Tk()
screen.title("My First Game")

#Create a board
board = Tkinter.Canvas(screen,width=500,height=500)
board.pack()

screen.mainloop()

问题:我怎样才能创建板的视觉表示，以便为每个列表，有一个矩形?另外，有没有办法检测，当一个矩形被点击并替换相应的列表值?

Question: How can i create a visual representation of the board, so that for every list, there is a rectangle? Also, is there a way to detect, when a rectangle is clicked and replace the corresponding list value?

推荐答案

我创建了一个标签板并根据点击的颜色为它们着色:

I created a board of labels and color them according to which is clicked:

import Tkinter as tk

board = [ [None]*10 for _ in range(10) ]

counter = 0

root = tk.Tk()

def on_click(i,j,event):
    global counter
    color = "red" if counter%2 else "black"
    event.widget.config(bg=color)
    board[i][j] = color
    counter += 1


for i,row in enumerate(board):
    for j,column in enumerate(row):
        L = tk.Label(root,text='    ',bg='grey')
        L.grid(row=i,column=j)
        L.bind('<Button-1>',lambda e,i=i,j=j: on_click(i,j,e))

root.mainloop()

这不会进行任何验证(例如，确保单击的元素位于底部).使用类而不是全局数据也会更好，但这对于感兴趣的编码人员来说是一个练习:).

This doesn't do any validation (to make sure that the element clicked is at the bottom for example). It would also be much better with classes instead of global data, but that's an exercise for the interested coder :).
