python实现简单的飞机大战游戏
本文实例为大家分享了python实现飞机大战游戏的具体代码，供大家参考，具体内容如下
1、准备环境
下载python(这里建议不需要安装最新的，好像pygame还没有对3.8支持的包，我也没去试)，安装pygame模块。
进入cmd：
输入“pip install pygame”——>显示“successfully”安装成功。
2、代码块:
import sys#退出程序
import pygame
class Settings():
def __init__(self):
self.screen_width=480
self.screen_height=852
self.bg_color = (255,192,203)
self.hero_speed = 2#控制飞机移速
self.bullet_speed = 4
self.bullet_width = 4
self.bullet_height = 8
self.bullet_color = (0,0,128)#设置子弹属性
self.enemy_speed = 1

self.rect.centerx = hero.rect.centerx#子弹与飞机中心保持一致
self.rect.y =hero.rect.y#y坐标也保持一致
self.y = float(hero.rect.y)#减小误差
