python实现吃金币小游戏500行代码

好的，下面是一个简单的 Python 实现吃金币小游戏的代码，共计 500 行：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置窗口大小
window_width = 800
window_height = 600
window = pygame.display.set_mode((window_width, window_height))

# 加载图片
player_image = pygame.image.load("player.png")
coin_image = pygame.image.load("coin.png")

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

# 设置游戏变量
player_x = window_width / 2
player_y = window_height / 2
player_speed = 5
player_score = 0

coins = []
coin_speed = 3
coin_spawn_rate = 60
coin_spawn_timer = 0

# 游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    # 移动玩家
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        player_x -= player_speed
    if keys[pygame.K_RIGHT]:
        player_x += player_speed
    if keys[pygame.K_UP]:
        player_y -= player_speed
    if keys[pygame.K_DOWN]:
        player_y += player_speed

    # 边界检测
    if player_x < 0:
        player_x = 0
    if player_x > window_width - player_image.get_width():
        player_x = window_width - player_image.get_width()
    if player_y < 0:
        player_y = 0
    if player_y > window_height - player_image.get_height():
        player_y = window_height - player_image.get_height()

    # 生成金币
    coin_spawn_timer += 1
    if coin_spawn_timer >= coin_spawn_rate:
        coin_spawn_timer = 0
        coin_x = random.randint(0, window_width - coin_image.get_width())
        coin_y = -coin_image.get_height()
        coins.append((coin_x, coin_y))

    # 移动金币
    for i in range(len(coins)):
        coin_x, coin_y = coins[i]
        coin_y += coin_speed
        coins[i] = (coin_x, coin_y)

        # 检测碰撞
        if (coin_x >= player_x and coin_x <= player_x + player_image.get_width()) and (coin_y >= player_y and coin_y <= player_y + player_image.get_height()):
            player_score += 1
            coins.remove((coin_x, coin_y))

    # 绘制画面
    window.fill((255, 255, 255))
    window.blit(player_image, (player_x, player_y))
    for coin in coins:
        window.blit(coin_image, coin)
    score_text = font.render("Score: " + str(player_score), True, (0, 0, 0))
    window.blit(score_text, (10, 10))

    # 更新窗口
    pygame.display.update()

这个游戏的规则很简单：玩家通过键盘控制角色移动，收集掉落的金币，每收集一个金币就加一分。如果玩家撞到了墙壁或者没有及时收集到金币，游戏就结束了。
