我正在使用基于海龟的网格设置创建扫雷风格的游戏。我需要找到网格内最近的单元格并显示位于其下方的图标，无论是炸弹还是数字图标。我不想做到精确，我只需要单击鼠标即可找到网格中最近的单元格，即使单击不是直接在板上。目前，我的代码仅显示板上创建的最后一只海龟的图标，然后通过进一步的单击不执行任何其他操作。
我该怎么做才能让它识别真正最接近的点击并多次执行直到找到最后一个炸弹？

我相信您正在以错误的方式处理这个问题。您正在激活screen.onclick()并试图将其映射到乌龟上。相反，激活turtle.onclick()在单个海龟上，选择海龟时将其停用。那么你就不必去搜索有问题的海龟，也不必主动忽略已经被选中的海龟。
下面是我将您的代码从这个问题和您之前的问题修改为您可以运行的示例。我不得不猜测 Cell 类的定义：
from turtle import Turtle, Screen
import random
class Cell(Turtle):
def __init__(self, number):
super().__init__("question.gif")
self.__number = number
self.penup()
def number(self):
return self.__number
class Game:
def __init__(self, size):
registershapes()
self.__boardsize = size
self.__boardlist = []
self.__bombnum = 0
self.__probe = 0
self.__rnums = None
offset = (size - 1) * 17
for y in range(size):
for x in range(size):
t = Cell(x + y * size)
t.goto(x * 34 - offset, offset - y * 34)
t.onclick(lambda x, y, self=t: closure(self))
self.__boardlist.append(t)
def hideMines(self, num):
if num > self.__boardsize ** 2:
return False
self.__bombnum = num
self.__rnums = []
i = 0
while i < self.__bombnum:
currentnum = random.randrange(0, self.__boardsize ** 2 - 1)
if currentnum not in self.__rnums:
self.__rnums.append(currentnum)
i += 1
return True
def probe(self, closest):
closest.onclick(None)
if closest.number() in self.__rnums:
closest.shape("bomb.gif")
self.__bombnum -= 1
else:
closest.shape("0.gif")
self.__probe += 1
return (self.__probe, self.__bombnum)
def registershapes():
screen.register_shape('0.gif')
# ...
screen.register_shape('bomb.gif')
screen.register_shape('question.gif')
def closure(closest):
_, rem = mine.probe(closest)
if rem == 0:
over = screen.textinput("Text Input", "Would you like to play again? (Y)es or (N)o")
if over.upper() == 'Y':
main()
else:
screen.bye()
def main():
global mine
board = screen.numinput("Numeric Input", "Enter desired board size: ")
mine = Game(int(board))
nummine = screen.numinput("Numeric Input", "Enter desired number of mines: ")
mine.hideMines(int(nummine))
screen = Screen()
mine = None
main()
screen.mainloop()
