飞机大战游戏python代码

以下是一个简单的飞机大战游戏的 Python 代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 设置屏幕大小
SCREEN_WIDTH = 700
SCREEN_HEIGHT = 500
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

# 设置游戏标题
pygame.display.set_caption("飞机大战")

# 加载图片
player_img = pygame.image.load("player.png").convert()
enemy_img = pygame.image.load("enemy.png").convert()

# 设置字体
font = pygame.font.Font(None, 36)

# 游戏结束标志
game_over = False

# 玩家
player_x = 300
player_y = 400
player_speed = 5

# 敌人
enemies = []
enemy_speed = 3

# 得分
score = 0


# 生成敌人
def create_enemy():
    enemy_x = random.randint(0, SCREEN_WIDTH - enemy_img.get_width())
    enemy_y = -enemy_img.get_height()
    enemies.append([enemy_x, enemy_y])


# 更新敌人位置
def update_enemies():
    for i, enemy in enumerate(enemies):
        enemy[1] += enemy_speed
        if enemy[1] > SCREEN_HEIGHT:
            del enemies[i]


# 检查碰撞
def check_collision():
    global game_over, score
    for i, enemy in enumerate(enemies):
        if (player_x < enemy[0] + enemy_img.get_width() and
                player_x + player_img.get_width() > enemy[0] and
                player_y < enemy[1] + enemy_img.get_height() and
                player_y + player_img.get_height() > enemy[1]):
            game_over = True
            score_text = font.render("得分: {}".format(score), True, WHITE)
            screen.blit(score_text, [SCREEN_WIDTH // 2 - score_text.get_width() // 2, SCREEN_HEIGHT // 2 - score_text.get_height() // 2])
            pygame.display.flip()
            pygame.time.wait(3000)
            break


# 游戏循环
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                player_x -= player_speed
            elif event.key == pygame.K_RIGHT:
                player_x += player_speed

    # 更新玩家位置
    if player_x < 0:
        player_x = 0
    elif player_x > SCREEN_WIDTH - player_img.get_width():
        player_x = SCREEN_WIDTH - player_img.get_width()

    # 更新敌人位置
    if len(enemies) < 10:
        create_enemy()
    update_enemies()

    # 检查碰撞
    check_collision()

    # 绘制背景
    screen.fill(BLACK)

    # 绘制玩家
    screen.blit(player_img, [player_x, player_y])

    # 绘制敌人
    for enemy in enemies:
        screen.blit(enemy_img, enemy)

    # 显示得分
    score += len(enemies)
    score_text = font.render("得分: {}".format(score), True, WHITE)
    screen.blit(score_text, [10, 10])

    # 更新屏幕
    pygame.display.flip()

# 退出 Pygame
pygame.quit()

这个示例中，玩家可以使用左右键来移动飞机，敌人会从顶部随机位置出现并向下移动，玩家需要躲避敌人并尽可能地击败他们来获得更高的分数。当玩家与敌人发生碰撞时，游戏将结束，并显示最终得分。
