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
| 程序文件 | 功能 |
|---|---|
| game.py | 在游戏中就运行的文件 |
| initgame.py | 游戏主菜单选择关卡等 |
| loading.py | 游戏载入等待缓存 |
| surface.py | 游戏入口点击这里 |
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 pygame
from sys import exit
from 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 True
return False
def 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 = 1
Timer = 0
flagblit = False
flagclick = False
pygame.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.pos
flagblit=eventinit(mosx,mosy,loadbar_width,loadbar_height)
if event.type == MOUSEBUTTONDOWN:
mosx,mosy=event.pos
flagclick=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1
elif flagblit:
screen.blit(loadbar2,(80,455))#开始按钮图片2
if flagclick: #进入游戏
GameRun = 0
pygame.time.delay(250)
#Timer+=1
pygame.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,os
from sys import exit
from pygame.locals import *
pygame.init()
def loading(screen,xpos_add_values):
pygame.display.flip()
gamerun = True
FlagMeterEmpty = 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()//2
xpos_width = 0
Timer = 0
Timer_loading_font = 0
fo = pygame.font.Font('font/msyh.ttf',25)
fontlist = [
'. ','.. ','...'
]
fl_i = 0
while 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+=1
if Timer_loading_font == 5:
Timer_loading_font=0
fl_i += 1
if fl_i==3:
fl_i = 0
if xpos_width<145:
xpos_width += 5
else:
#绘制满进度
screen.fill([0,0,0])
screen.blit(FlagMeterFull,(xpos,ypos))
#启动定时器
Timer += xpos_add_values
if Timer >= 30:
gamerun = False
pygame.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

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！
