我的代码绘制网格并设置X和Os。我的问题是它在屏幕的右上角完成了所有操作。我想找到一种方法来做到这一切,但中心。问题是我希望它尽可能美观。一切正常,除了职位外,我完全没有问题。我无法找到将我的电路板设置在屏幕中央的命令。

答案 0 :(得分:0)
由于这个问题是关于电路板的中心问题,我在下面的示例代码中删除了除了电路板图之外的所有内容。关键是要在零点附近进行数学运算,因此井字板中线对的位置之间只有它们的符号真正不同:
from turtle import Turtle, Screen
def tttDrawLineFromEnd(pen, orientation, lineLength):
pen.setheading(orientation)
pen.down()
pen.forward(lineLength)
def tttDrawGrid(pen, cellSize):
for sign in (-1, 1):
pen.up()
pen.goto(-3 * cellSize / 2, sign * cellSize / 2)
tttDrawLineFromEnd(pen, 0, 3 * cellSize)
for sign in (-1, 1):
pen.up()
pen.goto(sign * cellSize / 2, -3 * cellSize / 2)
tttDrawLineFromEnd(pen, 90, 3 * cellSize)
def ttt(cellSize):
marker = Turtle(visible=False)
marker.width(3)
marker.color('purple')
tttDrawGrid(marker, cellSize)
ttt(100)
screen = Screen()
screen.exitonclick()
我使用乌龟编程时使用的一个技巧是在我创建乌龟之后,我打电话给turtle.dot()
在屏幕的正中心显示一个可见的位置,所以我知道我是否正在绘制我所期望的位置。然后我在最终代码中删除了这个调试帮助。
