Python Pygame實(shí)戰(zhàn)之塔防游戲的實(shí)現(xiàn)
更新時(shí)間：2022年03月17日 10:54:39 作者：LexSaints
這篇文章主要介紹了如何利用Python中的Pygame模塊制作簡(jiǎn)單的塔防小游戲，文中的示例代碼講解詳細(xì)，感興趣的小伙伴可以跟隨小編一起動(dòng)手試一試
一、環(huán)境要求
windows系統(tǒng)，python3.6+
安裝模塊
pip install pyqt5 pip install pygame
二、游戲介紹
1、游戲目標(biāo)
按照關(guān)卡，設(shè)計(jì)不同的塔防地圖（博主只設(shè)計(jì)了三關(guān)，有興趣的同學(xué)，學(xué)會(huì)之后，可以自己畫(huà)地圖），設(shè)置三種炮臺(tái)，每種炮臺(tái)發(fā)射不同的炮彈，每種炮彈對(duì)敵人殺傷力不一樣，每種
炮臺(tái)的價(jià)格也不一樣。玩家通過(guò)錢(qián)幣購(gòu)買(mǎi)炮臺(tái)，并設(shè)有剪出炮臺(tái)的操作（有點(diǎn)類(lèi)似植物大戰(zhàn)僵尸里的鏟子）。敵人成功抵達(dá)塔樓，游戲結(jié)束。
2、先上游戲效果圖
三、完整開(kāi)發(fā)流程
1、項(xiàng)目主結(jié)構(gòu)
首先，先整理一下項(xiàng)目的主結(jié)構(gòu)，其實(shí)看一下主結(jié)構(gòu)，基本就清晰了
2、詳細(xì)配置
config.py
配置文件中，需要引入os模塊，并且配置打開(kāi)游戲的屏幕大小，并將資源中引用到的圖片、音頻插入到合適的位置。
因?yàn)槲覀兊拿詫m游戲，需要?jiǎng)濋_(kāi)模塊。

turrent.py 以炮塔類(lèi)為例
炮塔首先需要初始化，即init函數(shù)，另外需要有射擊屬性、以及重置屬性（即我們可以將已經(jīng)建好的炮塔刪除，然后重新添加）

如果你配置了開(kāi)發(fā)工具的環(huán)境VScode、sublimeText、notepad+、pycharm什么的，可以直接在工具中，運(yùn)行游戲。
如果沒(méi)配置，可以使用命令啟動(dòng)。
2、命令行啟動(dòng) gif
進(jìn)入代碼根目錄，按住shift+鼠標(biāo)右鍵，選擇 此處運(yùn)行powershell，然后執(zhí)行代碼：python tower.py
即可 運(yùn)行。
