一、游戏简介

本游戏是通过python编写的小游戏，给初学者熟悉python编程语言抛砖引玉，希望有所帮助。
成型的效果图如下：

在这里插入图片描述

二、编写步骤

1.引入库

代码如下：

###### AUTHOR:破茧狂龙 ######
###### DATE:20201002 ######
###### DESCRIPTION:移动的木板 ######
import pygame
from pygame.locals import *
import sys
import time
import random

2.初始化

代码如下：

pygame.init()
BLACK = (0, 0, 0) # 黑色
WHITE = (255, 255, 255) # 白色
bg_color = (0,0,70)  # 背景颜色
red = (200, 0, 0)
green = (0, 200, 0)
bright_red = (255, 0, 0)
bright_green = (0, 255, 0)smallText = pygame.font.SysFont('SimHei', 20) #comicsansms
midlText = pygame.font.SysFont('SimHei', 50)barsize = [30, 10]
SCREEN_SIZE = [400, 500]  # 屏幕大小
BALL_SIZE = [15, 15]  # 球的尺寸
fontcolor = (255,255,255)  # 定义字体的颜色myimg = r"img\b1.jpg"
background = pygame.image.load(myimg) # 图片位置
background = pygame.transform.scale(background, SCREEN_SIZE)# ball 初始位置
ball_pos_x = SCREEN_SIZE[0] // 2 - BALL_SIZE[0] / 2
ball_pos_y = 0# ball 移动方向
ball_dir_y = 1  # 1:down
ball_pos = pygame.Rect(ball_pos_x, ball_pos_y, BALL_SIZE[0], BALL_SIZE[1])clock = pygame.time.Clock()  # 定时器
screen = pygame.display.set_mode(SCREEN_SIZE)
# 设置标题
pygame.display.set_caption('python小游戏-移动木板')
# 设置图标
image = pygame.image.load(myimg)
pygame.display.set_icon(image)

3.相关自定义函数

代码如下：

###### 自定义函数 ######
def button(msg, x, y, w, h, ic, ac, action=None):mouse = pygame.mouse.get_pos()click = pygame.mouse.get_pressed()if x + w > mouse[0] > x and y + h > mouse[1] > y:pygame.draw.rect(screen, ac, (x, y, w, h))if click[0] == 1 and action != None:action()else:pygame.draw.rect(screen, ic, (x, y, w, h))textSurf, textRect = text_objects(msg, smallText)textRect.center = ((x + (w / 2)), (y + (h / 2)))screen.blit(textSurf, textRect)def text_objects(text, font):textSurface = font.render(text, True, fontcolor)return textSurface, textSurface.get_rect()def quitgame():pygame.quit()quit()def message_diaplay(text):largeText = pygame.font.SysFont('SimHei', 115)TextSurf, TextRect = text_objects(text, largeText)TextRect.center = ((screen[0] / 2), (screen[1] / 2))screen.blit(TextSurf, TextRect)pygame.display.update()time.sleep(2)game_loop()

4.相关自定义函数

代码如下：
