[Python] 开发植物大战僵尸游戏

用python开发植物大战僵尸

早期的植物大战僵尸是由vc开发的，作者的想法是非常地有特色，所以今天我们来探讨下植物大战僵尸游戏的进入场景怎么开发。

我们首需要用到如下几个文件

首先介绍surface.py:

主菜单稍微有点小长，不过代码中标识了注释也不难理解，在文件中我加入了很多图片素材都是原班植物大战僵尸的素材，后面还加了音乐提升游戏的趣味性！

编译后如下：

接着开发initgame.py文件：

# -*- coding:utf-8 -*-import pygamefrom sys import exitfrom pygame.locals import *pygame.init()def eventinit(mosx,mosy,loadbar_width,loadbar_height):if mosx>80 and mosx<loadbar_width+80:if mosy>450 and mosy<loadbar_height+450:return Truereturn Falsedef inits(screen):bg = pygame.image.load('images/Logo.jpg').convert_alpha()logoword = pygame.image.load('images/LogoWord.jpg').convert_alpha()loadbar = pygame.image.load('images/interface/LoadBar.png').convert_alpha()loadbar_width,loadbar_height = loadbar.get_width(),loadbar.get_height()loadbar2 = pygame.image.load('images/interface/LoadBar11.png').convert_alpha()GameRun = 1Timer = 0flagblit = Falseflagclick = Falsepygame.display.flip()while GameRun:for event in pygame.event.get():if event.type == QUIT:exit()if event.type == KEYDOWN:if event.key == K_RETURN:GameRun = 0 #进入游戏pygame.time.delay(250)if event.type == MOUSEMOTION:mosx,mosy=event.posflagblit=eventinit(mosx,mosy,loadbar_width,loadbar_height)if event.type == MOUSEBUTTONDOWN:mosx,mosy=event.posflagclick=eventinit(mosx,mosy,loadbar_width,loadbar_height)screen.blit(bg,(0,0)) #logo壁纸screen.blit(logoword,(320,16))#中文壁纸#开始按钮系列if not flagblit:screen.blit(loadbar,(80,450)) #开始按钮图片1elif flagblit:screen.blit(loadbar2,(80,455))#开始按钮图片2if flagclick: #进入游戏GameRun = 0pygame.time.delay(250)#Timer+=1pygame.time.delay(10)pygame.display.update()

然后运行程序得到的结果为：

哈哈，是不是很精彩了，没错这就是程序和图片的魅力！

接着剖析loading.py:

# -*- coding:utf-8 -*-import pygame,osfrom sys import exitfrom pygame.locals import *pygame.init()def loading(screen,xpos_add_values):pygame.display.flip()gamerun = TrueFlagMeterEmpty = pygame.image.load('images/interface/FlagMeterEmpty.png').convert_alpha()FlagMeterFull = pygame.image.load('images/interface/FlagMeterFull.png').convert_alpha()FlagMeterParts1 = pygame.image.load('images/interface/FlagMeterParts1.png').convert_alpha()xpos,ypos=450-FlagMeterEmpty.get_width()//2,300-FlagMeterEmpty.get_height()//2xpos_width = 0Timer = 0Timer_loading_font = 0fo = pygame.font.Font('font/msyh.ttf',25)fontlist = ['. ','.. ','...']fl_i = 0while gamerun:for event in pygame.event.get():if event.type == QUIT:exit()screen.fill([0,0,0])#----------#进度条系列#----------#绘制空进度条载入中。。。screen.blit(FlagMeterEmpty,(xpos,ypos))pygame.draw.rect(screen, (255,255,100), (xpos+7,ypos+7,xpos_width,7))screen.blit(FlagMeterParts1,(xpos+7+xpos_width,ypos))myfont = fo.render("载入中%s"%(fontlist[fl_i]), True, (0, 200, 0))screen.blit(myfont,(450-myfont.get_width()//2,ypos+100))#载入字体Timer_loading_font+=1if Timer_loading_font == 5:Timer_loading_font=0fl_i += 1if fl_i==3:fl_i = 0if xpos_width<145:xpos_width += 5else:#绘制满进度screen.fill([0,0,0])screen.blit(FlagMeterFull,(xpos,ypos))#启动定时器Timer += xpos_add_valuesif Timer >= 30:gamerun = Falsepygame.time.delay(xpos_add_values)pygame.display.update()

上面的loading.py是载入游戏等待时显示的一个动画，可以看做是一个过载动画。

最后插入游戏中设计的场景代码

game.py

# -*- coding:utf-8 -*-import pygame,osfrom sys import exitfrom random import randint as r_ifrom pygame.locals import *pygame.init()import initgameimport loadingdef

button.get_width(),button.get_height()fo = pygame.font.Font('font/msyh.ttf',21)myfont = fo.render("暂 停", True, (0, 230, 0))myfont2 = fo.render("菜 单", True, (0, 230, 0))plantshadow =

敲击回车，运行游戏结果如下图：

我们看到僵尸的位置是随机的，这里我们用到了随机算法，让僵尸固定在一个区域随机生成。

结果是不是很有趣了，真正的完成了一个植物大战僵尸的场景。但是要完全开发一个植物大战僵尸还需要一定的时间呢，作者抽空完成！
