首先，第一步，游戏简单素材的准备。
其次，思路整理。
我们需要几个类，分别是玩家类，敌人类，炮弹类及地图类，开始游戏界面以及结束界面，血条等等。
开始coding。
主函数，new一个对象（java乱入emmm），声明一个对象。
# encoding : utf-8
# anthor : comi
from gameloop import *
from pygame import *
import pygame,sys,time
if __name__ == '__main__':
player = game() # 声明一个类对象
player.game_start('KEEP-GOING') # 调用开始函数
while player.playing: # 进入游戏运行
player.new() # 开始游戏
player.screen.fill(black)
player.game_start('GAME-OVER') # 游戏结束
time.sleep(1.5) # 可以不要
这里可以根据自己的需要进行更改相关代码
接下来 游戏的主循环
# encoding : utf-8
# author : comi
from setting import *
from pygame import *
from Sprite import *
import pygame,sys
vec = pygame.math.Vector2
class game: # 游戏类 包含循环等
def __init__(self): # 初始化

self.FpsClock = pygame.time.Clock() # 设置游戏的刷新率
self.playing = True # 进入游戏的状态
self.running = True # 游戏运行的状态
self.Waiting = True # 游戏等待的状态
self.Pblood = 100 # 玩家血量
self.Eblood = 100 # 敌人血量
self.player = Player() # 声明一个游戏玩家对象
self.enemy = Enemy() # 声明一个敌人对象
self.all_groups = pygame.sprite.Group() # 通过pygame自带的 group 来判断碰撞检测
self.player_groups = pygame.sprite.Group()
self.Map_groups = pygame.sprite.Group()

在主循环内实现了很多功能，文本窗口展示，血条展示，以及整个游戏循环的定义都是可以拿来借鉴的，我也是从油管主上学来的。
接下来，精灵类，包含玩家，敌人。子弹，地图四部分。

有想法的同学可以和我交流，欢迎大家留言。
最后，运行效果如下 ，双人操作 p1：w a s d space 开火 p2： 上 下左 右 p 开火
