以下是一个简单的桌球游戏的示例代码：
import pygame
import random
# 初始化pygame
pygame.init()
# 设置屏幕大小和标题
screen_width = 800
screen_height = 500
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption('Desktop Billiards')
# 定义颜色常量
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
# 定义球和杆的类
class Ball:
def __init__(self, x, y, radius, color, velocity=(0, 0)):
self.x = x
self.y = y
self.radius = radius
self.color = color
self.velocity = velocity
def move(self):
self.x += self.velocity[0]
self.y += self.velocity[1]
def draw(self, screen):
pygame.draw.circle(screen, self.color, (int(self.x), int(self.y)), self.radius)
class CueStick:
def __init__(self, x, y, length, color):
self.x = x
self.y = y
self.length = length
self.color = color
self.angle = 0
def set_angle(self, event):
if event.type == pygame.MOUSEMOTION:
self.angle = pygame.math.Vector2(event.pos[0], event.pos[1]).angle_to((self.x, self.y))
def draw(self, screen):
pygame.draw.line(screen, self.color, (self.x, self.y), (self.x + self.length * math.cos(self.angle), self.y + self.length * math.sin(self.angle)), 5)
# 实例化球和杆
ball = Ball(screen_width / 2, screen_height / 2, 10, WHITE, (5, -5))
cue_stick = CueStick(screen_width / 2, screen_height - 20, 50, RED)
# 游戏循环
running = True
clock = pygame.time.Clock()
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
cue_stick.set_angle(event)
# 移动球
ball.move()
# 检测球是否撞击墙壁
if ball.x - ball.radius > screen_width or ball.x + ball.radius < 0:
ball.velocity[0] = -ball.velocity[0]
if ball.y - ball.radius > screen_height or ball.y + ball.radius < 0:
ball.velocity[1] = -ball.velocity[1]
# 清除屏幕
screen.fill(BLACK)
# 绘制球和杆
ball.draw(screen)
cue_stick.draw(screen)
# 更新屏幕显示
pygame.display.flip()
# 控制游戏帧率
clock.tick(60)
# 退出pygame
pygame.quit()
这段代码创建了一个简单的桌球游戏，你可以通过鼠标移动杆来控制球的方向。球会以固定的速度移动，并在碰到屏幕边缘时反弹。这个例子提供了桌球游戏的基本元素，但没有包括分数追踪、玩家输胜判断或者玩家控制的更多复杂性。
