Question

我目前正在使用graphics.py，我正试图弄清楚如何将一堆线移动到一起。我写的程序绘制了一个线条网格，我不确定如何写一些东西，每隔X秒移动整个网格1,1秒。有没有办法将所有线合并在一起？或者，怎么会这样做呢？

from graphics import *
win = GraphWin("Thing",500,500)
win.setCoords(0.0, 0.0, 10.0, 10.0)
a = 0
slength = 1
while True:
    a = a + slength
    vgrid = Line(Point(a,0),Point(a,500))
    hgrid = Line(Point(0,a),Point(500,a))
    vgrid.draw(win)
    hgrid.draw(win)

你可以尝试将它们存储在一个类中，然后一起访问它们的位置。请记住，我对graphics.py库一无所知，但您应该可以执行win = GraphWin("Thing",500,500) win.setCoords(0.0, 0.0, 10.0, 10.0) class MyDrawing: def __init__(self): self.horizontals = [] self.verticals = [] a = 0 slength = 1 while True: a = a + slength self.verticals.append(Line(Point(a,0),Point(a,500))) self.horizontals.append(hgrid = Line(Point(0,a),Point(500,a))) for line in self.verticals: line.draw(win) for line in self.horizontals: line.draw(win) def move(self, x, y): for line in self.verticals: line.Point1 = Point(line.Point1.x + x, line.Point1.y + y) line.Point2 = Point(line.Point2.x + x, line.Point2.y + y) for line in self.horizontals: line.Point1 = Point(line.Point1.x + x, line.Point1.y + y) line.Point2 = Point(line.Point2.x + x, line.Point2.y + y)之类的操作。然后你应该能够做到：
