Python Pygame實戰(zhàn)之塔防游戲的實現(xiàn)
更新時間：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模塊制作簡單的塔防小游戲，文中的示例代碼講解詳細，感興趣的小伙伴可以跟隨小編一起動手試一試
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
按照關(guān)卡，設(shè)計不同的塔防地圖（博主只設(shè)計了三關(guān)，有興趣的同學，學會之后，可以自己畫地圖），設(shè)置三種炮臺，每種炮臺發(fā)射不同的炮彈，每種炮彈對敵人殺傷力不一樣，每種
炮臺的價格也不一樣。玩家通過錢幣購買炮臺，并設(shè)有剪出炮臺的操作（有點類似植物大戰(zhàn)僵尸里的鏟子）。敵人成功抵達塔樓，游戲結(jié)束。
2、先上游戲效果圖
三、完整開發(fā)流程
1、項目主結(jié)構(gòu)
首先，先整理一下項目的主結(jié)構(gòu)，其實看一下主結(jié)構(gòu)，基本就清晰了
2、詳細配置
config.py
配置文件中，需要引入os模塊，并且配置打開游戲的屏幕大小，并將資源中引用到的圖片、音頻插入到合適的位置。
因為我們的迷宮游戲，需要劃開模塊。

'''屏幕大小'''
SCREENSIZE = (800, 600)

}3、定義敵人、塔樓、子彈的類
turrent.py 以炮塔類為例
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）
import pygame
from .arrow import Arrow
'''炮塔類'''
class Turret(pygame.sprite.Sprite):

self.image = pygame.image.load(self.imagepaths[turret_type])
self.rect = self.image.get_rect()
# 箭
self.arrow = Arrow(turret_type, cfg)
# 當前的位置
self.coord = 0, 0
self.position = 0, 0
self.rect.left, self.rect.top = self.position
self.reset()
'''射擊'''
def shot(self, position, angle=None):
arrow = None
if not self.is_cooling:
arrow = Arrow(self.turret_type, self.cfg)
arrow.reset(position, angle)
self.is_cooling = True
if self.is_cooling:
self.cool_time -= 1
if self.cool_time == 0:
self.reset()
return arrow
'''重置'''
def reset(self):
if self.turret_type == 0:
# 價格
self.price = 500
# 射箭的冷卻時間
self.cool_time = 30
# 是否在冷卻期
self.is_cooling = False
elif self.turret_type == 1:
self.price = 1000

main()四、游戲啟動方法
1、開發(fā)工具啟動
如果你配置了開發(fā)工具的環(huán)境VScode、sublimeText、notepad+、pycharm什么的，可以直接在工具中，運行游戲。
如果沒配置，可以使用命令啟動。
2、命令行啟動 gif
進入代碼根目錄，按住shift+鼠標右鍵，選擇 此處運行powershell，然后執(zhí)行代碼：python tower.py
即可 運行。
