# Introduction

"Because of you, I am willing to be a better person and don't want to be your burden, so I work hard,

Just to prove that I'm good enough for you. " - "listening"

Hello, hello! I'm kimiko~

I have written a confession copy before: Tuttle draws many source code projects of villain, love and villain love! And children's shoes, remember

Yeah? If you don't remember, you can go to Kangkang again. The link is as follows:

If I have time today, I want to upgrade the project of villain launching love. Want to learn - follow Xiaobian

Make a noise~

# text

Before drawing, it is also necessary to understand the basic operation. The operation can be divided into three categories: motion operation, setting operation and global control

Operation. I didn't know what was mentioned in that small project before. Let's do it again.

1) Brush movement operation

 turtle.forward(distance) turtle.fd(distance)
Moves distance pixels in the direction of the current brush

turtle.backward(distance)

turtle.back(distance)

turtle.bk(distance)

Moves distance pixels in the opposite direction of the current brush

turtle.right(degree)

turtle.rt(degree)

Rotate degree ° clockwise

turtle.left(degree)

turtle.lt(degree)

Rotate degree ° counterclockwise

turtle.th(angle)

Set the brush direction to angle

Standard mode: 0 - east 90 - North 180 - West 270 - South

Sign mode 0 - North 90 - east 180 - South 270 - West

turtle.pendown()

turtle.down()

turtle.pd()

Write

turtle.penup()

turtle.up()

turtle.pu()

write

turtle.goto(x,y)

turtle.steps(x,y)

turtle.setposition(x,y)

Move the brush to coordinates x, y
turtle.home()Move the brush to the coordinate origin

2) Brush setting operation

 turtle.fillcolor(colorstring) The fill color of the drawing turtle.color(color1, color2) Set pencolor = Color1 and fillcolor = color2 at the same time turtle.filling() Returns whether it is currently filled turtle.begin_fill() Ready to start filling the drawing turtle.end_fill() Filling is completed; turtle.hideturtle() Hide arrow display; turtle.showturtle() Do not draw graphics when moving. Lift the pen for drawing in another place

3) Global operation

 turtle.clear() Clear the turtle window, but the position and status of the turtle will not change turtle.reset() Clear the window and reset the turtle state to the initial state turtle.undo() Undo the last turtle action turtle.isvisible() Returns whether the current turtle is visible stamp() Copy current drawing turtle.write(s[,font=("font-name",font_size,"font_type")]) Write text, s is the text content, font is the font parameter, which is the font name, size and type respectively; Font is optional, and the parameter of font is also optional

1) Effect display (video display at the end of the article)

1.1 interface countdown——

1.2Interface text——

1.3 result display——

2) The code display steps are as follows

2.1 draw villains and launch love

```def draw_people(x, y):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.pensize(2)
turtle.color('black')
turtle.circle(35, 360)
turtle.penup()
turtle.pensize(3)
turtle.fd(45)
turtle.fd(20)
turtle.fd(35)
turtle.pendown()
turtle.circle(4, 360)
turtle.penup()
turtle.goto(x, y)
turtle.pensize(2)
turtle.fd(20)
turtle.fd(20)
turtle.pendown()
turtle.circle(5, 180)
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.fd(20)
turtle.fd(35)
turtle.fd(10)
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.fd(40)
turtle.fd(35)
turtle.fd(10)
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.fd(60)
turtle.fd(60)
turtle.bk(60)
turtle.fd(30)
turtle.fd(35)
turtle.penup()```

2.2 draw an arrow through the heart

```def draw_heart(size):
turtle.color('red', 'pink')
turtle.pensize(2)
turtle.pendown()
turtle.begin_fill()
turtle.fd(size)
turtle.circle(size * -3.745, 45)
turtle.circle(size * -1.431, 165)
turtle.left(120)
turtle.circle(size * -1.431, 165)
turtle.circle(size * -3.745, 45)
turtle.fd(size)
turtle.end_fill()

# Draw arrow feather
def draw_feather(size):
angle = 30  # Inclination of arrow
feather_num = size // 6 # number of feathers
feather_length = size // 3 # feather length
feather_gap = size // 10 # feather spacing
for i in range(feather_num):
draw_line(feather_gap, angle + 180, False)  # Arrow handle, no turning back
draw_line(feather_length, angle + 145, True)  # Wings, turn back
draw_line(feather_length, angle + 145, False)
draw_line(feather_num * feather_gap, angle, False)
draw_line(feather_length, angle + 145 + 180, False)
for i in range(feather_num):
draw_line(feather_gap, angle + 180, False)  # Arrow handle, no turning back
draw_line(feather_length, angle - 145, True)  # Wings, turn back
draw_line(feather_length, angle - 145, False)
draw_line(feather_num * feather_gap, angle, False)
draw_line(feather_length, angle - 145 + 180, False)

# Draw an arrow through the heart. At last, the head of the arrow is not drawn. It is replaced by a turtle
def arrow_heart(x, y, size):
go_start(x, y, False)
draw_heart(size * 1.15)
turtle.penup()
turtle.fd(size * 2.2)
draw_heart(size)
turtle.penup()
turtle.fd(size * 2.2)
turtle.color('black')
draw_feather(size)
turtle.pensize(4)
turtle.pendown()
turtle.fd(size * 2)
turtle.penup()
turtle.fd(size * 5.7)
turtle.color('black')
turtle.pensize(4)
turtle.pendown()
turtle.fd(size * 1.2)```

2.3 display countdown 3-1

```def draw_0(i):
turtle.speed(0)
turtle.penup()
turtle.hideturtle()  # Hide arrow display
turtle.goto(-50, -100)
turtle.color('red')
write = turtle.write(i, font=('Song typeface', 200, 'normal'))
time.sleep(1)```

2.4 show cute and accept

```def draw_1():
turtle.penup()
turtle.hideturtle()  # Hide arrow display
turtle.goto(-250, 0)
turtle.color('red')
write = turtle.write('Cute, take it', font=('Song typeface', 60, 'normal'))
time.sleep(2)```

2.5 display ❤ Qinghuan in the world ❤

```def draw_3():
turtle.penup()
turtle.hideturtle()  # Hide arrow display
turtle.goto(-220, 50)
turtle.color('red')
write = turtle.write('❤human world', font=('Song typeface', 60, 'normal'))
turtle.penup()
turtle.goto(0, -50)
write = turtle.write('Qinghuan❤', font=('Song typeface', 60, 'normal'))
time.sleep(2)```

2.6 display an arrow through the heart and text wood ❤ Fans

```def draw_4():
turtle.speed(10)
turtle.penup()
turtle.goto(-210, -200)
turtle.color('blue')
turtle.pendown()
turtle.write('Muzi      Fans', font=('wisdom', 50, 'normal'))
turtle.speed(1)
turtle.penup()
turtle.color("red")
turtle.goto(-31, -200)
turtle.write('❤', font=('wisdom', 50, 'normal'))
arrow_heart(20, -60, 51)
turtle.showturtle()```
