1 游戲介紹

《坦克大戰(zhàn)》是由日本南夢(mèng)宮Namco游戲公司開(kāi)發(fā)的一款平面射擊游戲，于1985年發(fā)售。游戲以坦克戰(zhàn)斗及保衛(wèi)基地為主題，屬于策略型聯(lián)機(jī)類(lèi)。

同時(shí)也是FC平臺(tái)上少有的內(nèi)建關(guān)卡編輯器的幾個(gè)游戲之一，玩家可自己創(chuàng)建獨(dú)特的關(guān)卡，并通過(guò)獲取一些道具使坦克和基地得到強(qiáng)化。

今天我們利用python實(shí)現(xiàn)簡(jiǎn)易版坦克大戰(zhàn)游戲。

3 開(kāi)發(fā)工具

3.1 環(huán)境配置

• Python版本：3.6.4

• 相關(guān)模塊：

• pygame模塊；

• 以及一些Python自帶的模塊。

3.2 Pygame介紹

簡(jiǎn)介

Pygame是一系列專(zhuān)門(mén)為編寫(xiě)電子游戲而設(shè)計(jì)的Python模塊(modules)。Pygame在已經(jīng)非常優(yōu)秀的SDL庫(kù)的基礎(chǔ)上增加了許多功能。這讓你能夠用Python語(yǔ)言編寫(xiě)出豐富多彩的游戲程序。

Pygame可移植性高，幾乎能在任何平臺(tái)和操作系統(tǒng)上運(yùn)行。

Pygame已經(jīng)被下載過(guò)數(shù)百萬(wàn)次。

Pygame免費(fèi)開(kāi)源。它在LGPL許可證(Lesser General Public License，GNU寬通用公共許可證)下發(fā)行。使用Pygame，你可以創(chuàng)造出免費(fèi)開(kāi)源，可共享，或者商業(yè)化的游戲。詳情請(qǐng)見(jiàn)LGPL許可證。

優(yōu)點(diǎn)

• 能夠輕松使用多核CPU(multi core CPUs) :如今雙核CPU很常用，8核CPU在桌面系統(tǒng)中也很便宜，而利用好多核系統(tǒng)，能讓你在你的游戲中實(shí)現(xiàn)更多東西。特定的pygame函數(shù)能夠釋放令人生畏的python GIL(全局解釋器鎖),這幾乎是你用C語(yǔ)言才能做的事。

• 核心函數(shù)用最優(yōu)化的C語(yǔ)言或匯編語(yǔ)言編寫(xiě):C語(yǔ)言代碼通常比Python代碼運(yùn)行速度快10-20倍。而匯編語(yǔ)言編寫(xiě)的代碼(assembly code)比Python甚至快到100多倍。

• 安裝便捷:一般僅需包管理程序或二進(jìn)制系統(tǒng)程序便能安裝。

• 真正地可移植:支持Linux (主要發(fā)行版), Windows (95, 98, ME, 2000, XP, Vista, 64-bit Windows,), Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX等操作系統(tǒng).也能支持AmigaOS, Dreamcast, Atari, AIX, OSF/Tru64, RISC OS, SymbianOS and OS/2，但是還沒(méi)有受到官方認(rèn)可。你也可以在手持設(shè)備,游戲控制臺(tái)， One Laptop Per Child (OLPC) computer項(xiàng)目的電腦等設(shè)備中使用pygame.

• 用法簡(jiǎn)單:無(wú)論是小孩子還是大人都能學(xué)會(huì)用pygame來(lái)制作射擊類(lèi)游戲。

• 很多Pygame游戲已發(fā)行:其中包括很多游戲大賽入圍作品、非常受歡迎的開(kāi)源可分享的游戲。

• 由你來(lái)控制主循環(huán):由你來(lái)調(diào)用pygame的函數(shù)，pygame的函數(shù)并不需要調(diào)用你的函數(shù)。當(dāng)你同時(shí)還在使用其他庫(kù)來(lái)編寫(xiě)各種各種的程序時(shí)，這能夠?yàn)槟闾峁O大的掌控權(quán)。

• 不需要GUI就能使用所有函數(shù):僅在命令行中，你就可以使用pygame的某些函數(shù)來(lái)處理圖片，獲取游戲桿輸入，播放音樂(lè)……

• 對(duì)bug反應(yīng)迅速:很多bug在被上報(bào)的1小時(shí)內(nèi)就能被我們修復(fù)。雖然有時(shí)候我們確實(shí)會(huì)卡在某一個(gè)bug上很久，但大多數(shù)時(shí)候我們都是很不錯(cuò)的bug修復(fù)者。如今bug的上報(bào)已經(jīng)很少了，因?yàn)樵S多bug早已被我們修復(fù)。

• 代碼量少:pygame并沒(méi)有數(shù)以萬(wàn)計(jì)的也許你永遠(yuǎn)用不到的冗雜代碼。pygame的核心代碼一直保持著簡(jiǎn)潔特點(diǎn)，其他附加物諸如GUI庫(kù)等，都是在核心代碼之外單獨(dú)設(shè)計(jì)研發(fā)的。

• 模塊化:你可以單獨(dú)使用pygame的某個(gè)模塊。想要換著使用一個(gè)別的聲音處理庫(kù)？沒(méi)問(wèn)題。pygame的很多核心模塊支持獨(dú)立初始化與使用。

最小開(kāi)發(fā)框架

import pygame,sys #sys是python的標(biāo)準(zhǔn)庫(kù)，提供Python運(yùn)行時(shí)環(huán)境變量的操控

pygame.init()  #內(nèi)部各功能模塊進(jìn)行初始化創(chuàng)建及變量設(shè)置，默認(rèn)調(diào)用
size = width,height = 800,600  #設(shè)置游戲窗口大小，分別是寬度和高度
screen = pygame.display.set_mode(size)  #初始化顯示窗口
pygame.display.set_caption("小游戲程序")  #設(shè)置顯示窗口的標(biāo)題內(nèi)容，是一個(gè)字符串類(lèi)型
while True:  #無(wú)限循環(huán)，直到Python運(yùn)行時(shí)退出結(jié)束
    for event in pygame.event.get():  #從Pygame的事件隊(duì)列中取出事件，并從隊(duì)列中刪除該事件
        if event.type == pygame.QUIT:  #獲得事件類(lèi)型，并逐類(lèi)響應(yīng)
            sys.exit()   #用于退出結(jié)束游戲并退出          
    pygame.display.update()  #對(duì)顯示窗口進(jìn)行更新，默認(rèn)窗口全部重繪
