小游戏

import pygame
import sys
import random

初始化pygame

pygame.init()

确保中文正常显示

pygame.font.init()
font = pygame.font.SysFont(['SimHei', 'WenQuanYi Micro Hei', 'Heiti TC'], 30)

游戏窗口设置

WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("躲避方块")

颜色定义

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

玩家设置

player_size = 50
player_pos = [WIDTH // 2 - player_size // 2, HEIGHT - player_size * 2]
player_speed = 10

敌人设置

enemy_size = 50
enemy_pos = [random.randint(0, WIDTH - enemy_size), 0]
enemy_list = [enemy_pos]
enemy_speed = 5

游戏变量

score = 0
game_over = False
clock = pygame.time.Clock()

生成敌人

def drop_enemies():
delay = random.random()
if len(enemy_list) < 10 and delay < 0.1:
x_pos = random.randint(0, WIDTH - enemy_size)
y_pos = 0
enemy_list.append([x_pos, y_pos])

绘制敌人

def draw_enemies(enemy_list):
for enemy_pos in enemy_list:
pygame.draw.rect(screen, RED, (enemy_pos[0], enemy_pos[1], enemy_size, enemy_size))

更新敌人位置

def update_enemies_position(enemy_list, score):
for idx, enemy_pos in enumerate(enemy_list):
enemy_pos[1] += enemy_speed + score // 10 # 随着分数增加，敌人速度加快
if enemy_pos[1] >= HEIGHT:
enemy_list.pop(idx)
score += 1
return score

检测碰撞

def detect_collision(player_pos, enemy_pos):
p_x, p_y = player_pos
e_x, e_y = enemy_pos

if (e_x >= p_x and e_x < (p_x + player_size)) or (p_x >= e_x and p_x < (e_x + enemy_size)):
    if (e_y >= p_y and e_y < (p_y + player_size)) or (p_y >= e_y and p_y < (e_y + enemy_size)):
        return True
return False

检查所有碰撞

def check_collisions(player_pos, enemy_list):
for enemy_pos in enemy_list:
if detect_collision(player_pos, enemy_pos):
return True
return False

游戏主循环

while not game_over:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()

    # 键盘控制
    if event.type == pygame.KEYDOWN:
        x = player_pos[0]
        if event.key == pygame.K_LEFT and x > 0:
            x -= player_speed
        if event.key == pygame.K_RIGHT and x < WIDTH - player_size:
            x += player_speed
        player_pos[0] = x

screen.fill(WHITE)

# 更新游戏状态
drop_enemies()
score = update_enemies_position(enemy_list, score)
game_over = check_collisions(player_pos, enemy_list)

# 绘制游戏元素
pygame.draw.rect(screen, BLUE, (player_pos[0], player_pos[1], player_size, player_size))
draw_enemies(enemy_list)

# 显示分数
text = font.render(f"分数: {score}", True, BLACK)
screen.blit(text, [10, 10])

# 显示控制提示
controls = font.render("方向键左右移动", True, BLACK)
screen.blit(controls, [WIDTH - 250, 10])

pygame.display.update()
clock.tick(30)  # 控制游戏帧率

游戏结束画面

screen.fill(WHITE)
text = font.render(f"游戏结束! 最终分数: {score}", True, BLACK)
text_rect = text.get_rect(center=(WIDTH//2, HEIGHT//2))
screen.blit(text, text_rect)

restart_text = font.render("按 R 键重新开始，按 Q 键退出", True, BLACK)
restart_rect = restart_text.get_rect(center=(WIDTH//2, HEIGHT//2 + 50))
screen.blit(restart_text, restart_rect)

pygame.display.update()

等待用户操作

while True:
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:
# 重置游戏状态
player_pos = [WIDTH // 2 - player_size // 2, HEIGHT - player_size * 2]
enemy_list = [enemy_pos]
score = 0
game_over = False
# 重新进入游戏主循环
exec(open("avoidance_game.py").read())
if event.key == pygame.K_q:
pygame.quit()
sys.exit()
