python小游戏有积分和关卡代码

好的，我可以给你提供一个简单的Python打飞机游戏代码，其中包括了积分和关卡的实现。代码如下：

import pygame
import random

# 初始化游戏
pygame.init()

# 定义屏幕大小和帧率
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("打飞机")
clock = pygame.time.Clock()
FPS = 60

# 加载游戏资源
background = pygame.image.load("images/background.png").convert()
player_img = pygame.image.load("images/player.png").convert_alpha()
player_rect = player_img.get_rect()
enemy_img = pygame.image.load("images/enemy.png").convert_alpha()
bullet_img = pygame.image.load("images/bullet.png").convert_alpha()

# 定义玩家、敌机、子弹和得分
player_speed = 5
player_rect.left = (screen_width - player_rect.width) // 2
player_rect.top = screen_height - player_rect.height - 50
player_score = 0
enemies = []
bullets = []
max_enemy_speed = 5
max_enemies = 10
current_wave = 1

# 定义文字
font = pygame.font.SysFont("arial", 24)
score_text = font.render("得分：%d" % player_score, True, (255, 255, 255))
wave_text = font.render("波数：%d" % current_wave, True, (255, 255, 255))

# 定义游戏状态
running = True

# 定义游戏循环
while running:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                running = False
            elif event.key == pygame.K_SPACE:
                bullet_rect = bullet_img.get_rect()
                bullet_rect.left = player_rect.left + player_rect.width // 2 - bullet_rect.width // 2
                bullet_rect.top = player_rect.top - bullet_rect.height
                bullets.append(bullet_rect)

    # 处理玩家移动
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and player_rect.left > 0:
        player_rect.left -= player_speed
    elif keys[pygame.K_RIGHT] and player_rect.right < screen_width:
        player_rect.left += player_speed
    elif keys[pygame.K_UP] and player_rect.top > 0:
        player_rect.top -= player_speed
    elif keys[pygame.K_DOWN] and player_rect.bottom < screen_height:
        player_rect.top += player_speed

    # 处理敌机生成和移动
    if len(enemies) < max_enemies:
        enemy_rect = enemy_img.get_rect()
        enemy_rect.left = random.randint(0, screen_width - enemy_rect.width)
        enemy_rect.top = -enemy_rect.height
        enemy_speed = random.randint(1, max_enemy_speed)
        enemies.append((enemy_rect, enemy_speed))

    for i, (enemy_rect, enemy_speed) in enumerate(enemies):
        enemy_rect.top += enemy_speed
        if enemy_rect.top > screen_height:
            enemies.pop(i)

    # 处理子弹移动和碰撞检测
    for i, bullet_rect in enumerate(bullets):
        bullet_rect.top -= 10
        if bullet_rect.top < 0:
            bullets.pop(i)
            continue

        for j, (enemy_rect, enemy_speed) in enumerate(enemies):
            if bullet_rect.colliderect(enemy_rect):
                bullets.pop(i)
                enemies.pop(j)
                player_score += 10
                break

    # 处理关卡升级
    if player_score >= current_wave * 100:
        current_wave += 1
        max_enemy_speed += 1
        max_enemies += 2
        wave_text = font.render("波数：%d" % current_wave, True, (255, 255, 255))

    # 绘制游戏界面
    screen.blit(background, (0, 0))
    screen.blit(player_img, player_rect)
    for enemy_rect, _ in enemies:
        screen.blit(enemy_img, enemy_rect)
    for bullet_rect in bullets:
        screen.blit(bullet_img, bullet_rect)
    score_text = font.render("得分：%d" % player_score, True, (255, 255, 255))
    screen.blit(score_text, (10, 10))
    screen.blit(wave_text, (10, 40))
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(FPS)

# 退出游戏
pygame.quit()

在这个代码中，我们定义了一个`player_score`变量来存储玩家得分，每次击落敌机得分加10。在游戏循环中，我们使用`current_wave`变量来表示当前关卡，每过100分就升级一次关卡，同时增加敌机的数量和速度，提高游戏难度。我们还使用了`score_text`和`wave_text`两个变量来显示得分和关卡信息。
