填充蟒蛇中不寻常的形状

Question

我正在尝试用海龟制作迪士尼介绍，但是城堡的这一部分不想正确填充，我不明白为什么。

这是代码：

import turtle

t1 = turtle.Turtle()
t2 = turtle.Turtle()

background_color = "#1b3f9f"
castle_color = "#78b3d3"

def goto_168_64():
    t1.penup()
    t2.penup()
    t1.goto(168,64)
    t2.goto(-168,64)
    t1.pendown()
    t2.pendown()

def background():
    t1.hideturtle()
    t2.hideturtle()
    turtle.bgcolor(background_color)

def draw():
    goto_168_64()
    t1.fillcolor(castle_color)
    t2.fillcolor(castle_color)
    t1.begin_fill()
    t2.begin_fill()
    t1.goto(40,64)
    t2.goto(-40,64)
    t1.setheading(90)
    t2.setheading(90)
    for x in range(23):
        t1.forward(2)
        t2.forward(2)
        t1.left(4)
        t2.right(4)
    t1.setheading(180)
    t2.setheading(0)
    t1.forward(25)
    t2.forward(25)
    goto_168_64()
    t1.setheading(180)
    t2.setheading(0)
    for x in range(23):
        t1.forward(2)
        t2.forward(2)
        t1.right(4)
        t2.left(4)
    t1.setheading(90)
    t2.setheading(90)
    t1.forward(10)
    t2.forward(10)
    t1.setheading(180)
    t2.setheading(0)
    t1.forward(140)
    t2.forward(140)
    t1.penup()
    t2.penup()
    t1.goto(0,103)
    t2.goto(0,103)
    t1.pendown()
    t2.pendown()
    t1.goto(0,93)
    t2.goto(0,93)
    t1.end_fill()
    t2.end_fill()

background()
draw()
turtle.mainloop()

如果我们将其视为单个多边形，您可能可以用更少的一只乌龟和十几行代码来获得您想要的东西：

from turtle import Screen, Turtle

background_color = "#1b3f9f"
castle_color = "#78b3d3"

def draw():
    t1.penup()
    t1.goto(168, 64)
    t1.pendown()

    t1.begin_fill()

    t1.setheading(180)
    t1.forward(128)
    t1.setheading(90)

    for _ in range(23):
        t1.forward(2)
        t1.left(4)

    t1.setheading(180)
    t1.forward(11)

    for _ in range(23):
        t1.forward(2)
        t1.left(4)

    t1.setheading(180)
    t1.forward(128)
    t1.setheading(0)

    for _ in range(23):
        t1.forward(2)
        t1.left(4)

    t1.setheading(90)
    t1.forward(10)
    t1.setheading(0)
    t1.forward(264)
    t1.setheading(270)
    t1.forward(10)

    for _ in range(23):
        t1.forward(2)
        t1.left(4)

    t1.end_fill()

screen = Screen()
screen.bgcolor(background_color)

t1 = Turtle()
t1.hideturtle()
t1.fillcolor(castle_color)

draw()

screen.mainloop()

您可以通过使用变量 (或变量）用于相关绘图方向并在循环中重复一半代码。
