飞机大战之python代码实现

2023年5月4日13:47:26Python代码

以下代码中，我们使用Pygame库来实现游戏窗口的创建、图片的加载、事件的处理、元素的绘制等功能。在游戏循环中，不断地更新游戏元素的位置和状态，并且不断地绘制游戏画面，从而实现了飞机大战游戏的基本功能。

以下是一个简单的飞机大战Python游戏代码实现：

import pygame
import random
# 初始化Pygame
pygame.init()
# 设置游戏窗口大小
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))
# 设置游戏标题
pygame.display.set_caption("飞机大战")
# 加载背景图片
background = pygame.image.load("images/background.png")
# 加载游戏结束图片
game_over = pygame.image.load("images/gameover.png")
# 加载飞机图片
player_image = pygame.image.load("images/player.png")
# 加载敌机图片
enemy_image = pygame.image.load("images/enemy.png")
# 加载子弹图片
bullet_image = pygame.image.load("images/bullet.png")
# 设置字体
font = pygame.font.SysFont(None, 48)
# 定义函数：绘制分数
def draw_score(score):
    score_text = font.render("Score: " + str(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))
# 定义函数：绘制飞机
def draw_player(player_x, player_y):
    screen.blit(player_image, (player_x, player_y))
# 定义函数：绘制敌机
def draw_enemy(enemy_x, enemy_y):
    screen.blit(enemy_image, (enemy_x, enemy_y))
# 定义函数：绘制子弹
def draw_bullet(bullet_x, bullet_y):
    screen.blit(bullet_image, (bullet_x, bullet_y))
# 定义函数：检测子弹是否击中敌机
def check_collision(enemy_x, enemy_y, bullet_x, bullet_y):
    if bullet_x >= enemy_x and bullet_x <= enemy_x + 50 and bullet_y >= enemy_y and bullet_y <= enemy_y + 50:
        return True
    else:
        return False
# 设置游戏循环
def game_loop():
    # 初始化游戏
    player_x = 215
    player_y = 600
    player_speed = 5
    enemy_x = random.randint(0, 430)
    enemy_y = -50
    enemy_speed = 2
    bullet_x = 0
    bullet_y = 0
    bullet_speed = 10
    score = 0
    game_running = True
    while game_running:
        # 处理事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_running = False
            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
                elif event.key == pygame.K_SPACE:
                    bullet_x = player_x + 25
                    bullet_y = player_y - 25
        # 移动敌机
        enemy_y += enemy_speed
        # 移动子弹
        if bullet_y > 0:
            bullet_y -= bullet_speed
        # 检测子弹是否击中敌机
        if check_collision(enemy_x, enemy_y, bullet_x, bullet_y):
            enemy_x = random.randint(0, 430)
            enemy_y = -50
            bullet_x = 0
            bullet_y = 0
            score += 10
        # 绘制游戏元素
        screen.blit(background, (0, 0))
        draw_score(score)
        draw_player(player_x, player_y)
        draw_enemy(enemy_x, enemy_y)
        draw_bullet(bullet_x, bullet_y)
        # 判断游戏是否结束
        if enemy_y > screen_height:
            screen.blit(game_over, (100, 250))
            pygame.display.update()
            pygame.time.delay(2000)
            game_running = False
        # 更新游戏画面
        pygame.display.update()
    # 结束游戏
    pygame.quit()
# 开始游戏
game_loop()

上述代码实现了一个简单的飞机大战游戏，游戏主要包含以下需求：
