用Python实现智能乒乓球游戏！

本文提供了一个 Python 实现的乒乓球游戏代码，你只需要将代码复制并粘贴到编辑器中即可。

你好，亲爱的 Python 爱好者，今天我想分享一下如何在 Python 中编写一个带有自定义机器人 AI 的乒乓球游戏。我们的挑战是制作两个用户，第一个用户是你，第二个用户是精准度达到 100% 的AI机器人。

Step 1

导入 turtle 和 Screen

# Step 1 import set up turtle and Screen
import turtle
import random
s = turtle.Screen()
s.title(Pong)
s.bgcolor(black)
s.setup(width=600, height=400)

Step 2

创建一个球

# Step 2 Create ball
ball = turtle.Turtle()
ball.speed(0)
ball.shape(circle)
ball.color(white)
ball.penup()
ball.goto(0, 0)
ball.dx = 4
ball.dy = 4

Step 3

创建一个 AI 挡板

# Step 3 Create AI paddle
ai = turtle.Turtle()
ai.speed(0)
ai.shape(square)
ai.color(white)
ai.penup()
ai.goto(-250, 0)
ai.shapesize(stretch_wid=5, stretch_len=1)

Step 4

创建自己的挡板




    
# Step 4 Create a paddle For You
you = turtle.Turtle()
you.speed(0)
you.shape(square)
you.color(white)
you.penup()
you.goto(250, 0)
you.shapesize(stretch_wid=5, stretch_len=1)

Step 5

创建移动AI挡板的函数

# Step 5 Create Function to move AI paddle
def move_ai_paddle():
    y = ball.ycor()
    if y > 0:
        ai.sety(ai.ycor() + 2)
    else:
        ai.sety(ai.ycor() - 2)

Step 6

创建一个函数以移动你的挡板并用键盘控制它

# Step 6 Create a Function to move the your paddle with up and down key
def paddle2_up():
    y = you.ycor()
    y += 20
    you.sety(y)

def paddle2_down():
    y = you.ycor()
    y -= 20
    you.sety(y)
# Your Paddle control it with key
s.listen()
s.onkeypress(paddle2_up, Up)
s.onkeypress(paddle2_down, Down)
Step 7 使用 while 循环开始游戏
# Step 7 Start the game with a while loop
while True:
    s.update()
    
    # Move the ball
    ball.setx(ball.xcor() + ball.dx)
    ball.sety(ball.ycor() + ball.dy)
    
    # Check for collisions with the walls
    if ball.ycor() > 190 or ball.ycor() < -190:
        ball.dy *= -1
    
    # Move the robot paddle towards the ball
    if ball.ycor() > ai.ycor():
        ai.sety(ai.ycor() + 4)
    elif ball.ycor() < ai.ycor():
        ai.sety(ai.ycor() - 4)
    
           # Check for end game conditions
    if ball.xcor() > 300:
        turtle.textinput(Game End, You Loss Pong Game With AI!)
        break
    if ball.xcor() < -300:
        turtle.textinput(Game End, You Win Pong Game With AI!)
        break
    



    
    # Check for collisions with the robot paddle
    if (ball.xcor() < -240 and ball.xcor() > -250) and (ball.ycor() < ai.ycor() + 40 and ball.ycor() > ai.ycor() - 40):
        if random.random() < 0.9: # 90% chance of collision
            ball.dx *= -1
    
        # Check for collisions with the user paddle
    if (ball.xcor() > 240 and ball.xcor() < 250) and (ball.ycor() < you.ycor() + 40 and ball.ycor() > you.ycor() - 40):
        ball.dx *= -1

s.title(Pong)
s.bgcolor(black)
s.setup(width=600, height=400)

# Step 2 Create ball
ball = turtle.Turtle()
ball.speed(0)
ball.shape(circle)
ball.color(white)

ball.goto(0, 0)
ball.dx = 4
ball.dy = 4

# Step 3 Create AI paddle
ai = turtle.Turtle()
ai.speed(0)
ai.shape(square)
ai.color(white)
ai.penup()
ai.goto(-250, 0)
ai.shapesize(stretch_wid=5, stretch_len=1)

# Step 4 Create a paddle For You

you.speed(0)
you.shape(square)
you.color(white)
you.penup()

# Step 5 Create Function to move AI paddle
def move_ai_paddle():
    y = ball.ycor()
    if y > 0:
        ai.sety(ai.ycor() + 2)
    else:
        ai.sety(ai.ycor() - 2)

# Step 6 Create a Function to move the your paddle
def paddle2_up():
    y = you.ycor()
    y += 20
    you.sety(y)

def paddle2_down():
    y = you.ycor()
    y -= 20
    you.sety(y)
# Your Paddle control it with key
s.listen()
s.onkeypress(paddle2_up, Up)
s.onkeypress(paddle2_down, Down)

# Step 7 Start the game with a while loop
while True:
    s.update()
    
    # Move the ball
    ball.setx(ball.xcor() + ball.dx)
    ball.sety(ball.ycor() + ball.dy)
    
    # Check for collisions with the walls
    if ball.ycor() > 190 or ball.ycor() < -190:
        ball.dy *= -1
    
    # Move the robot paddle towards the ball
    if ball.ycor() > ai.ycor():
        ai.sety(ai.ycor() + 4)
    elif ball.ycor() < ai.ycor():
        ai.sety(ai.ycor() - 4)



    
    
           # Check for end game conditions
    if ball.xcor() > 300:
        turtle.textinput(Game End, You Loss Pong Game With AI!)
        break
    if ball.xcor() < -300:
        turtle.textinput(Game End, You Win Pong Game With AI!)
        break
    
    # Check for collisions with the robot paddle
    if (ball.xcor() < -240 and ball.xcor() > -250) and (ball.ycor() < ai.ycor() + 40 and ball.ycor() > ai.ycor() - 40):
        if random.random() < 0.9: # 90% chance of collision
            ball.dx *= -1
    
        # Check for collisions with the user paddle
    if (ball.xcor() > 240 and ball.xcor() < 250) and (ball.ycor() < you.ycor() + 40 and ball.ycor() > you.ycor() - 40):
        ball.dx *= -1
