游戏代码

import pygame
import random
import sys

初始化pygame

pygame.init()

设置游戏窗口

WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("躲避方块 - 基础游戏示例")

确保中文能正常显示

pygame.font.init()
font = pygame.font.SysFont(["SimHei", "WenQuanYi Micro Hei", "Heiti TC"], 36)

颜色定义

WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)

玩家类

class Player:
def init(self):
self.width = 50
self.height = 50
self.x = WIDTH // 2 - self.width // 2
self.y = HEIGHT - self.height - 20
self.speed = 5
self.rect = pygame.Rect(self.x, self.y, self.width, self.height)

def move(self, keys):
if keys[pygame.K_LEFT] and self.x > 0:
self.x -= self.speed
if keys[pygame.K_RIGHT] and self.x < WIDTH - self.width:
self.x += self.speed
if keys[pygame.K_UP] and self.y > 0:
self.y -= self.speed
if keys[pygame.K_DOWN] and self.y < HEIGHT - self.height:
self.y += self.speed
self.rect.x = self.x
self.rect.y = self.y

def draw(self):
pygame.draw.rect(screen, GREEN, self.rect)

敌人类

class Enemy:
def init(self):
self.width = 40
self.height = 40
self.x = random.randint(0, WIDTH - self.width)
self.y = -self.height
self.speed = random.randint(3, 7)
self.rect = pygame.Rect(self.x, self.y, self.width, self.height)

def move(self):
self.y += self.speed
self.rect.y = self.y

def draw(self):
pygame.draw.rect(screen, RED, self.rect)

def is_off_screen(self):
return self.y > HEIGHT

def reset(self):
self.x = random.randint(0, WIDTH - self.width)
self.y = -self.height
self.speed = random.randint(3, 7)
self.rect.x = self.x
self.rect.y = self.y

游戏主类

class Game:
def init(self):
self.player = Player()
self.enemies = [Enemy() for _ in range(5)]
self.score = 0
self.game_over = False

def handle_events(self):
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_r and self.game_over:
self.init() # 重新开始游戏

def update(self):
if self.game_over:
return

移动玩家

keys = pygame.key.get_pressed()
self.player.move(keys)

移动敌人并检测碰撞

for enemy in self.enemies:
enemy.move()

敌人飞出屏幕或碰撞

if enemy.is_off_screen() or pygame.Rect.colliderect(self.player.rect, enemy.rect):
if pygame.Rect.colliderect(self.player.rect, enemy.rect):
self.game_over = True
else:
enemy.reset()
self.score += 1

def draw(self):
screen.fill(BLACK)

绘制玩家和敌人

self.player.draw()
for enemy in self.enemies:
enemy.draw()

绘制分数

score_text = font.render(f"分数: {self.score}", True, WHITE)
screen.blit(score_text, (10, 10))

游戏结束画面

if self.game_over:
game_over_text = font.render("游戏结束！按R键重新开始", True, WHITE)
text_rect = game_over_text.get_rect(center=(WIDTH//2, HEIGHT//2))
screen.blit(game_over_text, text_rect)

pygame.display.flip()

游戏主循环

def main():
clock = pygame.time.Clock()
game = Game()

while True:
game.handle_events()
game.update()
game.draw()
clock.tick(60) # 60 FPS

if name == "main":
main()
