游戏-飞机大战 (微信版)

飞机大战 (微信版)

使用python的pygame模块制作

学习游戏中的碰撞检测, 音效等

体会面向对象编程的思想

在此感谢小甲鱼老师提供的教学视频

1. 游戏界面如图:

2. 游戏的基本设定

我方飞机有三次机会, 每次被敌方飞机撞毁时, 新诞生的飞机会有3秒的安全期(无敌状态)

每隔30秒会有一个随机的道具补给,分为两种道具, 全屏炸弹和双倍子弹

我方初始有3个全屏炸弹, 上限也为3个, 功能是炸毁屏幕中所有敌方飞机

双倍子弹, 功能是使我方飞机一次射出两颗子弹, 持续19秒

我方飞机子弹射程不是全屏, 大概是屏幕长度的80%

敌方飞机有大中小3种, 速度分别为高中低3种速度

消灭小飞机需要1发子弹, 中飞机需要8发子弹, 大飞机需要2发子弹

每消灭一架小飞机得1000分, 中飞机得6000分, 大飞机10000分

游戏根据分数来逐步提高难度, 难度提高表现为, 敌方飞机数量增加, 敌方飞机速度加快

游戏分为4个等级

初始等级为1, 为 0分-50000分

等级2为 50000分-300000分

等级3为 300000分-600000分

等级4为 600000分-1000000分

游戏为中型敌机和大型敌机增加了血槽显示, 可以直观知道敌机还有多少生命

游戏结束时显示历史最高分数 (存放在record.txt中)
