python pygame 简单小游戏

最近学习了pygame，感觉十分有意思，花了一点时间制作了一个简单的小游戏

效果图

在这里插入图片描述
这是一个很简单的防守类小游戏
玩家可以使用wasd控制人物移动，并且鼠标控制人物旋转，发射元气弹消除敌人。敌人顺利到达城墙则玩家扣血，血量清零后游戏结束，反之坚持200秒则游戏胜利。

模块区

开头导入几个需要使用的模块和一个 Player类

import jieba
import os
import sys
import math
import random
import pygame
import datetime
from pygame.locals import *class Player(object):  #玩家 类def __init__(self, img, rect, speed):self.ful_img = imgself.img = self.ful_imgself.rect = rectself.speed = speedself.num = 0def update(self, screen, press_keys):  #键盘控制if press_keys[K_a]:self.rect.left -= self.speedif self.rect.left <= 0:self.rect.left = 0if press_keys[K_d]:self.rect.left += self.speedif self.rect.right >= 250:self.rect.right = 250if press_keys[K_w]:self.rect.top -= self.speedif self.rect.top <= 0:self.rect.top = 0if press_keys[K_s]:self.rect.top += self.speedif self.rect.bottom >= 800:self.rect.bottom = 800self.num += 1if self.num % 3 == 0:self.num = 0return [(self.rect.left + self.rect.right)/2, (self.rect.top + self.rect.bottom)/2], self.img

设置区

设置区包含了窗口设置区和基础设置区
基础设计区包含了游戏时间，玩家，城墙，元气弹，敌人等设计

游戏区

游戏区包含了游戏开始，进行，结束三个区块
布局了玩家，城墙，元气弹，以及怪物的生成。此外还有元气弹于怪物抵消，血量扣除，胜负判断等数个操作。
