Python实现接糖果小游戏

介绍:

基于Pygame的糖果从屏幕顶部下落的游戏代码。这个游戏包括了一个可以左右移动的篮子来接住下落的糖果，接住糖果会增加得分。

代码:

import pygame
import random
import os# 初始化pygame和设置屏幕大小
pygame.init()
screen_width, screen_height = 800, 600
screen = pygame.display.set_mode((screen_width, screen_height))# 设置颜色
WHITE = (255, 255, 255)
RED = (255, 0, 0)
ORANGE = (255, 128, 0)
BLACK = (0, 0, 0)# 糖果和篮子的尺寸
candy_width, candy_height = 30, 30
basket_width, basket_height = 100, 50# 初始化篮子的位置
basket_x = screen_width // 2
basket_y = screen_height - basket_height# 糖果列表
candies = []# 初始化得分
score = 0# 最高得分
highest_score = 0# 设置游戏运行时间（毫秒）
game_duration = 30000# 难度和对应的下落速度
DIFFICULTIES = {'Easy': 10,'Medium': 20,'Hard': 30
}# 按钮的位置和大小
