python游戏之飞机大战

简单的飞机大战

如下图所示，这就是我自己做的飞机大战，图片都是自己画的（系统自己的画图工具），声音是在网上下载的。参考了哔哩哔哩一个视频的逻辑，然后自己就想做，于是就做了一个简单的飞机大战，代码也是我自己想出来的，（废了我一上午的时间）.

简单的说一下过程

这是我的结构

因为是随意做的，所以说所有的代码都放在了一个文件Plane.py
有 1 个纯音乐（网上下载的）， 1 个我方飞机的图片， 1张我方飞机的子弹，1张敌方飞机的图片和1张敌方飞机的子弹

实现功能有

• 用户通过键盘控制我方飞机，按空格发射子弹
• 敌方飞机在指定的范围内自由移动，随机发射子弹
• 可以设置敌方飞机发射子弹的速度，
• 也可以设置我方的子弹速度和移动速度

主要思路

• 就是设计4个类，对着4个类进行一些逻辑操作
• 飞机与子弹的关系
  如图：
  

import pygame
import random
import time
from pygame.locals import *

# 设置屏幕大小
WIDTH = 800
HEIGT = 1000

# 飞机的图片和对应的大小
PLANE_IMG = "myplane.png"
PLANE_IMG_WIDTH = 96
PLANE_IMG_HEIGHT = 104

# 初始化 我方飞机的位置
PLANE_X = int((WIDTH - PLANE_IMG_WIDTH) / 2)
PLANE_Y = HEIGT - PLANE_IMG_HEIGHT

# 设置我方飞机子弹的图片，他对应的高度和宽度
MY_PLANE_BULLET = "myBullet.png"
MY_PLANE_BULLET_WIDTH = 19
MY_PLANE_BULLET_HEIGHT = 29

# 敌方飞机的图片和敌方飞机的图片大小
# 这样方便后期修改
ENEMY_PLANE = "enemy.png"
ENEMY_PLANE_WIDTH = 100
ENEMY_PLANE_HEIGHT = 105

# 敌方飞机的子弹和敌方飞机的图片
ENEMY_PLANE_BULLET = "enemyBullet.png"

# 设置我方子弹速度
MY_PLANE_BULLET_SPEED = 5

# 设置敌方子弹速度
ENEMY_PLANE_BULLET_SPEED = 3

# 设置敌方的难度
ENEMY_PLANE_MOVE_SPEED = 5
# 设置我方的移动速度
MY_PLANE_MOVE_SPEED = 40
