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
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 = img
self.img = self.ful_img
self.rect = rect
self.speed = speed
self.num = 0
def update(self, screen, press_keys): #键盘控制
if press_keys[K_a]:
self.rect.left -= self.speed
if self.rect.left <= 0:
self.rect.left = 0
if press_keys[K_d]:
self.rect.left += self.speed
if self.rect.right >= 250:
self.rect.right = 250
if press_keys[K_w]:
self.rect.top -= self.speed
if self.rect.top <= 0:
self.rect.top = 0
if press_keys[K_s]:
self.rect.top += self.speed
if self.rect.bottom >= 800:
self.rect.bottom = 800
self.num += 1
if self.num % 3 == 0:
self.num = 0
return [(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。
