Pygame实战：多年后“魂斗罗”像素风归来 不止是经典与情怀@全体成员

导语
​​​​​​​​​​​​​​​​​​

不知道红白机上的《魂斗罗》是不是小伙伴儿们小时候的经典回忆呢？反正木木子那时候貌似是有

的，BUT 女孩子一般是不玩儿这类游戏的！！

（哎呀，木木子是不是偷偷保住了我年龄的秘密......)⛲⛲

​

魂斗罗是一款经典动作射击闯关类游戏，在当时的游戏市场上，可以说是一款相当有挑战难度的游戏。毕竟那时候消息闭塞，压根没有攻略之说，更何况那时年少，玩游戏图的是爽快，很多人也不会刻意去深度研究卡位、战斗技巧等，就是最基础的突突突、闪闪闪，于是就有了N种死亡经历。

今天木木子带大家来看看如何打造Python像素版本的经典游戏——魂斗罗叭！

像素风游戏类型之前也有几款的哈比如：《我的世界》、《坦克大战》、《超级马里奥》......可以

看文末的文章汇总哈！往期的资料素材等都在顾木子的主页左侧信息获取哈！

这边是一个简易版本的魂斗罗哈，有大佬自行优化一波！纯分享给大家娱乐。

大家都知道Python版本的游戏编写基本上都是Pygame游戏模块，今天就用的这个哈。

 游戏规则：上下左右大家熟悉的——ASDW键，K跳跃，J放枪子儿。

打完一个小兵一个大boss就闯关成功了。嗯哼——超简单，有手就玩的赢的游戏23333！

一、准备中

1）素材准备

像素风格任务人物形象（仅部分）

背景图展示：

主要人物素材：（部分图）

​

2）环境安装

这款简易版本的《魂斗罗游戏》木木子环境设置的是：Python3、Pycharm、Pygame部分自带的不说了哈。

模块安装：

pip install -i https://pypi.douban.com/simple/ +模块名

 
​​​​​​​​​​​​​​​​​​

二、正式敲代码

1）游戏敌方boss出场以及定义。

		if self.pos_i >= 6:

			self.game_settings.boss_jump_vel = -12.0#恢复跳跃开始的速度

		if self.player.rect.centerx > self.rect.x :#or self.x < self.mx:

			#self.game_settings.boom_end = True
			self.game_settings.boss_boom_end = True

2）玩家定义的子弹设置

import pygame
from pygame.sprite import Sprite 

class Bullet(Sprite):

	def __init__(self,game_settings,screen,player):
		super().__init__()
		self.game_settings = game_settings
		self.player = player
		self.screen = screen
		self.image = pygame.image.load('图片/bullet1.png')
		self.rect = self.image.get_rect()
		self.rect.left = player.rect.right-20#开始子弹默认往右射击
		if self.player.player_direction == -1:
			self.rect.right = player.rect.left+20
		self.rect.centery = player.rect.centery-15
		if self.player.player_down:
			self.rect.centery = player.rect.centery#调整子弹位置
		if self.player.player_up:
			self.rect.bottom = player.rect.top+20
		self.x = float(self.rect.x)
		self.y = float(self.rect.y)
		self.mx = self.x#mx为保存初始x的坐标
		self.my = self.y
		self.speed_factor = game_settings.bullet_speed_factor

	def update(self):
		if self.yself.mx or self.x == self.mx:#默认为右方向
			self.x += self.speed_factor
			self.rect.x = self.x

	def blit_bullet(self):
	
		self.screen.blit(self.image,self.rect)

3）主程序

'''
csdn:顾木子吖
'''
import pygame
import sys
from pygame.locals import *
from settings import Settings
from game_player import Game_Player 
import game_functions as gf
from pygame.sprite import Group
from game_stats import GameStats
from game_boss import Game_Boss
from button import Button

def run_game():
	bg = pygame.image.load("图片/map01.jpeg")
	game_settings = Settings()
	pos_x = 0#地图移动o
	
	pygame.init()
	screen = pygame.display.set_mode(
		(game_settings.screen_width,game_settings.screen_height))
	pygame.display.set_caption("经典像素风游戏——魂斗罗")
	stats = GameStats(game_settings)
	player = Game_Player(game_settings,screen)
	bullets = Group()
	boss = Group()
	enemys = Group()
	win_button = Button(game_settings,screen,"YOU WIN")
	gf.create_legion(game_settings,screen,enemys)
	gf.create_boss(game_settings,screen,player,boss)

	while True:
		pygame.mouse.set_visible(False)
		gf.check_events(game_settings,screen,player,bullets)
		gf.update_player(game_settings,stats,player,enemys)
		gf.update_bullet(game_settings,bullets,screen,enemys,boss)	
		gf.update_enemys(game_settings,enemys)	
		gf.update_boss(game_settings,boss)
		gf.update_screen(game_settings,bg,pos_x,screen,player,bullets,enemys,boss,win_button)
		
		if player.moving_right and player.center > player.screen_rect.centerx and game_settings.boss_appear == False:
			game_settings.screen_rolling = True
			pos_x -= 5#屏幕滚动速度
		else:
			game_settings.screen_rolling = False
run_game()

等等等等.......游戏代码太多了。

​三、效果展示

我的速度调的比较快哈，自己调慢点儿。

1)Part 1 初始化界面‍♀️

2）Part 2 打BOSS‍♂️

3）Part 3 胜利

总结

嘿！新一轮的小游戏就写到这里结束啦，如需完整的资料项目点下方链接哦~

我还得想想下一个写什么内容呢——苦思冥想中。你们玩儿，我先撤了。
