Python弹球小游戏

以下是一个简单的Python弹球小游戏的代码示例。这个游戏使用了Pygame库来创建窗口和处理图像。

首先，确保安装了Pygame库：

pip install pygame

然后，可以使用以下代码来创建并运行游戏：

import pygame
import sys
 
# 初始化Pygame
pygame.init()
 
# 设置窗口大小
width, height = 800, 500
screen = pygame.display.set_mode((width, height))
 
# 设置游戏时钟
clock = pygame.time.Clock()
 
# 定义颜色常量
WHITE = (255, 255, 255)
 
# 定义球和球架的类
class Ball:
    def __init__(self, position, velocity, radius):
        self.position = position
        self.velocity = velocity
        self.radius = radius
        self.color = WHITE
 
    def move(self, time_passed):
        self.position[0] += self.velocity[0] * (time_passed / 1000.0)
        self.position[1] += self.velocity[1] * (time_passed / 1000.0)
 
    def draw(self, screen):
        pygame.draw.circle(screen, self.color, self.position, self.radius)
 
class Paddle:
    def __init__(self, position, width, height):
        self.position = position
        self.width = width
        self.height = height
        self.color = WHITE
        self.velocity = 5
 
    def move_left(self):
        self.position[0] -= self.velocity
 
    def move_right(self):
        self.position[0] += self.velocity
 
    def draw(self, screen):
        pygame.draw.rect(screen, self.color, (self.position[0], self.position[1], self.width, self.height))
 
# 实例化球和球架
ball = Ball([width / 2, height / 2], [3, -3], 10)
paddle = Paddle([width / 2 - 20, height - 20], 40, 10)
 
# 游戏循环标志
running = True
 
# 主游戏循环
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                paddle.move_left()
            elif event.key == pygame.K_RIGHT:
                paddle.move_right()
 
    # 更新游戏状态
    time_passed = clock.tick()
    ball.move(time_passed)
 
    # 判断球是否撞击球架
    if ball.position[1] + ball.radius > height - paddle.height and \
            ball.position[0] + ball.radius > paddle.position[0] and \
            ball.position[0] - ball.radius < paddle.position[0] + paddle.width:
        ball.velocity[1] = -ball.velocity[1]
 
    # 判断球是否撞击顶部或底部
    if ball.position[1] - ball.radius < 0 or ball.position[1] + ball.radius > height:
        ball.velocity[1] = -ball.velocity[1]
